Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
72. From paragraph 2 we know that _______.
A. animals are as clever as human beings
B. dogs are smarter than parrots and chimpanzees
C. chimpanzees have good word-learning skills
D. dogs have similar learning abilities as 3-year-old children
73. Both experiments show that_________.
A. Rico is smart enough to get all commands right
B. Rico can recognize different things including toys
C. Rico has developed the ability of learning mathematics
D. Rico won't forget the names of objects once recognizing them
74. Which of the following statements is true?
A. The purpose of the experiments is to show the border collie's mental abilities.
B. Rico has a better memory partly because of its proper early training.
C. The border collie is world-famous for recognizing objects.
D. Rico is born to understand its owner's commands.
75. What does the writer want to tell us in the last paragraph?
A. To train your dog.          B. To talk to your dog.
C. To be friendly to your dog.   D. To be careful with your dog.

With smart phones taking the world by Storm,a phone that Can only send and receive voice
calls and text messages may seem like a relic from a bygone age.Yet in East Africa,simple
phones like these are changing the face of the economy,thanks to the mobile money services that are spreading across the region.
Usilng the text-messaging function built into the GSM system(全球通)used by most cell
phone networks,these services allow people without a bank account or credit card to use their
phone as an electronic walletthat can be used to store.send or receive cash.
It works like this:you pay cash to your local agent who then tops up your mobile money
account using a secure form of text messaging.That money can be transferred(转账)to another
person by sending a message to their cell phone account.
For some the system is a lifeline.“If I didn,t have my mobile phone.1 would be very
poor,”says Neyasse Neemur,a mother of four children who lives in northern Kenya.“Now I
can sell fish.”
Neemur took up fishing in July last year,but making money from it was a little tricky,
especially as Turkana people do not usually eat fish.A truck from Ethiopia to Tanzania passes
through her village once a week,and she arranged to have the driver transport the fish several
hundred kilometres south to market in Kisumu.where relatives sell the fish.
“I get the money transfer immediately.”says Neemur.“Then I can pay for my children to go to school and for vegetables and beans,”she adds,“so I don’t need to eat fish.”
According to the Central Bank of Kenya,payments worth around l billion Kenyan shillings
($13 million)per day were transferred through Kenya,s mobile money systems in 2009,equalling
the country,s credit card transactions(业务).The bank expects mobile money transfers to overtake credit cards in 2010.
49.In Paragraph l,the author uses“simple phones”to________.
A.make a comparison    B.introduce a topic

In classrooms across the USA, students from different speech backgrounds give speeches in English. It is important to remember that the major goal of the speech is communication of ideas, not perfection of language skills. Therefore, as you listen to a speaker who is not fluent in the language, seek to understand what is being said by concentrating on the ideas of the message rather than on the specific words of the speaker. This may require a special kind of patience as well as the ability to take the perspective (视角) of the communicator. Perspective taking means that you can put yourself in the other person’s shoes. That is, you try to imagine what it would be like to give a speech in a foreign language to a group of native speakers of that language. Keep in mind that non-fluency is not linked to low intelligence or lack of education~ it is linked to experiences with the second language.
These guidelines can help you be a better listener in these situations.
1. Approach the speech with a positive attitude, and expect to understand.
2. Listen all the way through. Make special efforts to keep your mind from wandering in the middle of the speech. It may help to take notes.
3. Plan to give proper nonverbal (非语言的) feedback to prove your interest, patience, and support for the speaker.
4. Control your negative emotional responses. Let's face it, it is difficult to deal with linguistic barriers (语言障碍), and people often get disappointed or bored when there are language differences.
5. Do not laugh, even if the speakers do, at their language skills. Often they laugh nervously to relieve tension.
68. What is the main idea of this passage?
A. How to become a good listener.
B. How to become a good speaker.
C. We should take a positive attitude towards speech.
D. How to communicate with others
69. The underlined phrase "put yourself in the other person’s shoes" in the first paragraph means ____.
A. to know one's shoes is to know one's problem
B. try to wear the other person’s shoes
C. understand others by trying on their shoes
D. look at something from the point of others
70. What can we learn from the passage?
A. People should be strict with speakers speaking in a foreign language.
B. Taking notes helps keep your mind from wandering in listening to a speech.
C. Whenever the speaker is nervous, he laughs.
D. It's hard to concentrate when the speaker is not fluent.
71. What advice is given on listening to a speech?
A. Believing you can understand every word of the speech.
B. Showing your support for the speaker nonverbally.
C. Laughing when the speaker laughs at himself.
D. Commenting on the speech at times.

What does an astronaut eat in space? This is a question that will puzzle many, as people rarely think of that. In the early space-travel years, astronauts ate dehydrated (脱水的) foods that were eaten through straws (吸管). In today’s space-age, the food that they eat is totally different. They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety of foods in space. Some can be eaten in their natural form, like fruits, while some need to add water, like noodles. However, there are no refrigerators, so the food has to be prepared and eaten without being stored for a long time. When the astronauts are hungry, they simply eat the food by opening the food packages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which include breakfast, lunch and dinner. Sometimes they also eat snacks. The US space agency NASA has found out that an astronaut’s diet reduces by about 70% on a space mission, though he has a wide range of foods to choose from like nuts, chicken, beef, seafood, and candies. Drinks in the spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space foods that can be offered to astronauts when on space missions. 
45. Now astronauts eat ________ in space.
A. dehydrated (脱水的) foods           B. food as people do on Earth 
C. totally different                    D. food with a lot of water 
46. The food the astronauts prepared  ________ .
A. can’t be stored for a long time       B. can be put into refrigerators 
C. can be stored for a long time          D. can’t be kept in the food packages 
47. In space, astronauts ________ like people on Earth.
A. only have nuts, chicken and beef       B. onlyhave lunch for a day
C. only drink coffee, tea and lemonade    D. also eat three meals a day 
48. What are scientists experimenting and trying out?
A. Some very special snacks.             B. How astronauts can sleep well.
C. Different space foods for astronauts.     D. How to get some fruits for astronauts.

Science isn’t something mysterious, only for the few. Every one of us—whether a poet, worker, or physicist has to be able to think scientifically, and to understand some science, such as whether to smoke, what to eat, and what protection to use. Even for decisions that don’t depend on some scientific facts, science remains the proven set of best methods for getting exact information about the world.
Some people will end up as policy-makers in government or business. People such as these make decisions that affect the life of everyone, and most of them know no more about science than does the rest of the general public. Yet they are called upon to decide what to do about nuclear reactors(核反应堆), global warming, environmental toxins(环境霉素), expensive space programs, and biomedical research. It’s nonscientists, not scientists, who have the last word on whether the milk we drink can safely come from cows treated with medicine. To make such decisions wisely, the decision makers have to be drawn from a scientifically educated public.
Even if science is irrelevant(不相干的) to the lives of ordinary Americans, a strong scientific spirit is basic to our economy, educational system, and society. This requires lots of young people to become excited enough by science that they decide to become professional scientists. This also requires, to some degree, the support and understanding of the general public.
Scientists are not always able to communicate their findings in an easy-to-understand manner. Although the scientists should do a better job of explaining what they have discovered, members of the general public have to make efforts to understand what is being said.
46.What does the author mean by saying that “a strong scientific spirit is basic to the economy, educational system and society”?
A.School and society should encourage young people to become professional scientists.
B.The school should only teach lessons of economy and education·
C.A scientifically educated public is basic to the economy,educational system and society.
D.More scientists work in our economy, educational system and society.
47.The general public is required to _______.
A.support and understand the need of scientific education
B.check what the scientists are saying
C.give help to the policy-makers
D.become professional scientists
48.The main idea of this passage is _________.
A.policy—makers must be science professionals
B.science is not far from everyone’s life
C.science has nothing to do with ordinary Americans
D.science professionals make decisions that affect the life of everyone
49.According to the passage, who can decide whether the milk we drink can safely come from
cows treated with medicine?
A.Scientists      B.Young people      C.The public     D.Policy-makers

Shaping the Future of TV
Nobody can predict the future of TV with any certainty but some major figures in the industry have recently put forward their thoughts on what will shape TV of the future.
The shaping of a personalized television future is starting to take place, says Intel. The chip giant, who makes the processors found in most personal computers, states that by 2015 there will be just over 12 million devices using IPTV services that will be capable of connecting to over 500 billion hours of TV & video.
This supports the idea to make television a more social, personalized and readily accessible device available anywhere through IPTV services. As more and more people consume TV & video through various mediums, there is now a greater need to distribute and manage this content.
As such, companies like TV Genius are accepting this announcement made at Intel’s Developer Forum (IDF) in the USA by their chief technology officer, Justin Rattner.
With such a variety of content likely to become available, technology firms will need to assist in making personalized TV recommendations more readily accessible.
Mr. Rattner, speaking to the BBC said, “TV will remain at the centre of our lives and you will be able to watch what you want and where you want. We are talking about more than one TV-capable device for every man and woman on the planet. People are going to feel connected to the screen in ways they haven’t in the past.”
One way in which this will happen will also be assisted by a more united service of material combining including video content, internet content, broadcast content, and personal content.
This content will become much more accessible through remote devices like mobile phones using IPTV technology. This means that users will be able to watch their favorite programs away from the traditional media hub, the home.
63. The author uses the passage mainly to ________.
A. recommend a new type of TV          B. introduce a possible shape of future TV
C. describe the function of future TV   D. support the new type of TV
64. We know from the passage that the future TV might have major features like _______.
a. being capable of connecting to many more hours
b. changing the shape very easily        c. receiving programs at any place
d. displaying the advanced materials
e. using services accessing the Internet, video, radio, etc
A. a, b, c  B. c, d, e     C. a, c, e     D. b, c, e
65. The underlined word “this” in the third paragraph refers to __________.
A. Intel, the chip giant                  B. TV and video
C. readily accessible device            D. Widely used IPTV services
66. We can infer from the passage that _________.
A. the present TV will disappear in the near future
B. the future TV will have a beautiful look
C. people are developing the technology of TV very quickly
D. people will spend more time watching TV at home

      阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
A
Reading poems is not exactly an everyday activity for most people. In fact, many people never read a poem once they get out of high school.
It is worth reminding ourselves that this has not always been the case in America. In the nineteenth century, a usual American activity was to sit around the fireside in the evening and read poems aloud. It is true that there was no television at the time, nor movie theaters, nor World Wide Web, to provide diversion. However, poems were a source of pleasure, of self-education, of connection to other people or to the world beyond one’s own community. Reading them was a social act as well as an individual one, and perhaps even more social than individual. Writing poems to share with friends and relations was, like reading poems by the fireside, another way in which poetry has a place in everyday life.
How did things change? Why are most Americans no longer comfortable with poetry, and why do most people today think that a poem has nothing to tell them and that they can do well without poems?
There are, I believe, three culprits(肇事者):poets, teachers, and we ourselves. Of these, the least important is the third: the world surrounding the poem has betrayed us more than we have betrayed the poem. Early in the twentieth century, poetry in English headed into directions unfavorable to the reading of poetry. Readers decided that poems were not for the fireside or the easy chair at night, that they belonged where other difficult-to-read things belonged.
Poets failed the readers, so did teachers. They want their students to know something about the skills of a poem, they want their students to see that poems mean something. Yet what usually occurs when teachers push these concerns on their high school students is that young people decide poems are unpleasant crossword puzzles.
56.Reading poems is thought to be a social act in the nineteenth century because___________.
A.it built a link among people           B.it helped unite a community
C.it was a source of self-education     D.it was a source of pleasure
57. The underlined word “diversion”(in Paragraph 2) most probably means “________”.
A.concentration B.change         C.amusements   D.stories
58.According to the passage, what is the main cause of the great gap between readers and poetry?
A.Students are becoming less interested in poetry.
B.Students are poorly educated in high school.
C.TV and the Internet are more attractive than poetry.
D.Poems have become difficult to understand.
59.In the last paragraph, the writer questions_______.
A.the difficulty in studying poems       B.the way poems are taught in school
C.students’ wrong ideas about poetry        D.the techniques used in writing poems

On a good night when there is no Moon and the air is clear, only up to 4,000 or so stars can be seen by the unaided eye. From ancient times star – watchers have tried to bring some order into the sky by fitting the stars into patterns. The constellations (星座) to which names were given.
Observation of the night sky every few hours shows that in the northern hemisphere(半球) the stars appear to turn anticlockwise (逆时针方向) about a point near the Pole Star. As they turn, the stars keep the same positions in relation to each other, and in fact the appearance of the constellations has changed very little over the centuries. Like the Sun and Moon, the stars have a daily journey across the sky, rising upwards in the east and setting in the west – due to the Earth’s daily spin. The Circumpolar Stars, those near the Pole Star, are an exception to this; they are so close to the pole that they never disappear below the horizon (地平线) Although the stars always rise in the same places they do not do so at the same time every day. They rise about 4 minutes earlier each day since the Earth is progressing in its orbit around the Sun; in almost but not exactly a year they again rise and set at the same time. If a certain star is seen to rise in the east exactly when the Sun sets on a particular day, a few weeks later it will be seen well above the eastern horizon at sunset.
58.Which do you think is the best title of the passage above?
A.The Earth, the Moon and the Stars.       B.Motion of the Stars.
C.How to Watch the Stars.                       D.Appearance of the Stars.


 
59.Which of the following descriptions cannot be shown in the picture?

 
A.The Circumpolar stars never disappear below the horizon.
B.The relative position of the stars in a constellation remains more or less the same as they move.
C.Stars appear to turn about a point near the Pole Star.
D.Stars appear to turn anticlockwise in the northern hemisphere.
60.From the passage we can learn that __________.
A.scientists can observe only up to 4,000 stars on a clear night
B.every day the stars always rise in the same place at the same time
C.thousands of years later, people may have to rename the constellations as the positions of the stars in them have changed
D.since the earth spins from the west to the east every day, most stars rise in the east and set in the west
61.Where is the passage probably taken from?
A.A fashion magazine                             B.A newspaper advertisement.
C.A science textbook.                              D.A collection of science fiction stories.

C
It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic
variations(变异). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.
62. According to the text, DNA testing can NOT be used in _______ .
A. doing criminal investigations        B. deciding faraily law
C. clearmg wrongly accused people     D. telling twins apart
63. DNA samples are not popular with all the people because _______ .
A. the government in Britain establishes a criminal database
B. the US and Canada develop similar systems
C. DNA samples can be used to harm a person’s privacy
D. DNA testing is too expensive and dangerous now
64. Where will you most probably find this article?
A. In a guidebook.                   B. In a storybook.
C. In a science fiction.               D. In a scientific magazine.
65. Which is the best title for the passage?
A. Discovery of DNA testing by Jeffery  B. Practice of DNA testing in court
C. DNA testing in the present situation   D.Benefits and side effects of DNA testing
