C
Can you imagine a catfish bigger than a boy? There are more than 1,000 kinds of catfish;28 species are found in the United States' lakes and rivers. This huge family has some mighty strange members. Let's meet a few.
Walking catfish.Nature's feisty little catfish,found in southern Florida,has an extra lung for breathing on dry land. When its swimming hole dries up,the walking catfish waddles on stiff forward fins in search of another lake or stream.If an enemy attacks,the fish flares(展开)its top and front fins and leaps at the attacker to scare it off.
Armored catfish.This catfish has heavy,bony plates protecting its body. The shell makes the fish difficult to bone. To cook it,throw the fish whole into a fire. When it is done,break it open for eating.Some armored catfish are found in Florida,but the 100-pounders live in South America.
Rounding out the family of strange catfish are talking catfish,which make growing sound when you pull them from the water;climbing catfish,which move quickly up shore brush in search of food;electric catfish,which can deliver a mild shock;and blind catfish,which settle in the inky blackness of underwater caves.Blind catfish find food through taste buds in their eight whiskers(须).
Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water.The United States does not have catfish anywhere near the size of those in South America.But in some large U.S,rivers,blue and flathead catties do top 100 pounds.
Most of the catfish you are likely to catch will be much smaller,about frying pan size.When you catch one,remember that the top fins and the forward fins have poison glands(腺)at their bases. They can give you painful wounds (…)

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

D
The eruption of a volcano in the Canary Islands could trigger a “mega-tsunami”(巨大海啸)that would hit Atlantic coastlines with waves as high as 330 feet, scientists said on Wednesday. They said an eruption of the Cumbre Vieja volcano on La Palma, part of the Spanish island chain off West Africa, was likely to cause a massive chunk(大块)of rock to break off, crashing into the sea and kicking up huge walls of water higher than any other in recorded history. The tsunami would be capable of traveling huge distances at up to 500 miles an hour, the scientists said in a research paper to be published soon.
Simon Day, of the Benfield Greig Hazard Research Centre at the University College of London, said that as the volcano was not erupting at present, the short-term and medium-term risks were “negligible”. But Cumbre Vieja should be monitored closely for any signs of activity so that emergency services could plan an effective response, he said. “Eruptions of Cumbre Vieja occur at intervals of decades to a century or so and there may be a number of eruptions before its collapse(倒塌),” said Day, who cooperated on the research with Steven Ward of the University of California. “Although the year-to-year probability of a collapse is therefore low, the resulting tsunami would be a major disaster with indirect effects around the world.”
The effects would spread north, west and south of the Canaries, with the west Sahara bearing the worst of the wave’s energy. The energy released by the collapse would be equal to the electricity consumption of the entire United States in half a year.
Immediately after the landslide(山崩),a huge wave of water 93,000 feet high and tens of miles wide would form. As the landslide rocks moved deeper under water, a tsunami would develop. Within 10 minutes, the tsunami would have moved a distance of almost 155 miles. On the west Saharan shore, waves would probably reach heights of 330 feet.
Florida and the Caribbean, the final north Atlantic destinations to be affected by the tsunami, would have to brace themselves for 165-foot waves some eight to nine hours after the landslide. Wave heights toward Europe would be smaller, but substantial waves would hit the coasts of Britain, Spain Portugal and France. The research paper estimated water would penetrate several miles inland and that the devastation would cause trillions of dollars in damage.
76. What would be the result of a big chunk rock falling into the sea?
A. Waves would be very high.                                         B. The volcano would stop.
C. Walls of water would kick up a storm.                          D. An earthquake would take place.
77. The word “negligible”(Line 3, Paragraph 2) is closest in meaning to ______.
A. unimportant                    B. small                              C. predictable               D. avoidable
78. From the passage we may learn that the volcano erupts ______.
A. every year                                                                 B. every 5 to 9 years
C. every 10 to 100 years                                                        D. every 5 to 10 months
79. All of the following are true EXCEPT ______.
A future eruption of Cumbre Vieja volcano may experience a massive collapse
Waves generated by the landslide could even reach the coasts of the United States
The landslide-released energy is equal to half a year’s electricity consumption in the US
American scientists have managed to utilize the volcanic energy for civil purposes

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.

Here are two letters from our readers expressing their concern about school assessment (评价):
(l)
Students should be allowed to study without worrying about grades (学习成绩). Fortunately, most educators realize that students have different interests and abilities. However, grade-based assessment is still very common. Grades often hold back creativity. Competing for better grades causes many students to turn down opportunities to go in for music, drama and sports. Grades are also an unfair measure of a student’s ability. I do not demand, as some extremists do, that grades should no longer be recorded. However, I do believe that less importance should be placed on. grades. I hope that someday grades will become optional(可选择的) at Village High School.
Magdalena Smith, President
Drama Club
(2)
Let’s face the facts about grades. Grades perform three basic functions( 功能). First, grades get students to work at their highest level of competence  (能力 ). Second, they act as an encouragement for hard-working students and as a warming to those who are not. Finally, grades are an effective standard by which to measure students' achievement. Good grades help students to get jobs and to get into university.
I've spoken with a number of students who have jobs, and most of them say that they were hired mainly because of their grades. My grades helped me get a part-time job and will help me into university next year. I think grades are extremely important at Village High School.
Simon Harper, Member,
Science Club

A. insists grades should become optional in the near future

65. Magdalena Smith thinks it is important for       .
A. educators to assess the students by grades
B. educators to pay more attention to grades
C. students to compete for better grades
D. students to take part in music, drama, and sports
66. According to the letters, which of the following is TRUE about Village High School?
A. Grades are effective in every way.    
B. Grades hold back students' creativity. .

C
At present, in many American cities expecially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of a teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several years.
Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money—the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards.
Unruly students, especially in big cities, large classes and a lack of support from the public in terms of money and understanding have led many public school teachers to leave the profession.
As a result, many of the best students, who would have chosen teaching as their life career in the past, are going into other fields.
Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled.
Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But the change in a vast society like the United States is not easy. People’s attitudes have formed over many years, and sometimes change takes many years.
63.The underlined word “that” in Paragraph 1 refers to “      ”.
A.money             B.job
C.secretary          D.truck driver
64.What is the present situation of the teaching?
A.Teachers work harder and get underpaid.
B.Teahcers have no opportunities to work in other fields.
C.Teaching can attract best students to work as a teacher.
D.Teaching can provide rewards as well as high salaries.
65.Many public school teachers turn to other professions because        .
A.the government doesn’t finacially support them
B.they have to work longer hours than a lawyer
C.their students refuse to listen to them
D.they are not fairly treated
66.The author believes that change in teachers’ status in the United States       .
A.is not great     
B.is impossible
C.influences people’s attitude
D.needs time
