It was 3:21 a.m. when nine?year?old Glenn Kreamer awoke to the smell of burning. Except for the cracking(爆裂声) of flames somewhere below there was not a sound in the two?storey house at Baldwin, Long Island.
With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke?filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn.
The nine-year-old boy raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later,“acted with all the self?control of a trained adult.”
On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.
First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.
He could hear the fire engine coming up, but how would the firemen find his mother in the smoke?filled house where flames had almost swallowed up the ground floor?
Grasping firmly a ball of string from the garage, Glenn raced back into the
house and dashed upstairs to his mother's room. Tying one end of the string to her hand he ran back, laying out the string as he went, through the hall and back out into the garden.
Minutes later he was telling fire chief John Coughlan:“The string will lead
you to Mother.” Mrs Kreamer was carried to safety as the flames were breaking through her bedroom floor.
1.Why did Glenn run downstairs first?
A. He wanted to find out what was happening.
B. He was worried about his mother's safety.
C. He wanted to save his sister and his brother.
D. He went to see if his father had come back from work. 
2. How did Glenn help the firemen to save his mother?
A. By throwing water all over her and her bed.
B. By carrying her to safety with his brother.
C. By pushing and pulling at her.
D. By tying a string to her hand. 
3. Who called the fire brigade and ambulance service?
A. Glenn.       B. Glenn's father.       C. Glenn's sister.    D. Glenn's neighbor. 
4.What did Glenn do to protect himself?
A. He put a wet cloth around himself.   B. He threw water all over his head.
C. He hid himself in the bathroom.      D. He rushed out to the lawn. 
5. Glenn saved his family because ________ .

Section A (10 points)                                                     
Directions: Read the following passage. Complete the diagram by using the information from the passage. WRITE NO MORE THAN 3 WORDS for each answer.
Many students eat their breakfasts on the way to school or in the dinning-room. But some of them don’t really know how to eat well when eating out.
Here is some important advice. The first is to eat less fast food. The most obvious harm of eating too much fast food is weight gaining because of too much fat. Young people and adults are at risk of diseases related to weight.
Too much fast food can drag your body down. French fries, for example, were recently found to contain much more acryl amide(丙烯酰胺) than other food. This may cause cancer. Actually, deep fried food all contains acryl amide. So don’t eat it too often.
Soda is another thing you should watch out for. Cokes and other sodas contain a lot of sugar and can slow down a person’s calcium absorption, so it’s best to drink as little soda as possible.
Food in the dinning-room may not be as tasty as fast food, but it’s actually easier to make healthy choices. Human bodies need variety. You can have a meal that balances lean proteins, vitamins and complex carbohydrates(碳水化合物). In other words, a meal with fish or meat, vegetables and some bread or rice will provide you with most nutrients that the body needs.
Some snacks, on the other hand, will help keep you going until your next big meal. It is natural for teenagers, especially boys, to feel hungry during school time. Don’t forget to take some foods, like whole-grain biscuits or low-fat milk in your school bag.

Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.
Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?
Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine.
Ji(director Institute of Nanomedicine):
A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.
Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.
The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.
Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.
小题1:Which of the following shows the right relationship?
A.nanometer<millimeter<micrometer<meter

There are little cars that may some day take the place of today’s automobiles(汽车). If everyone drives such a little car in the future, there will be less pollution in the air, there will be more parking space in cities, and the streets will be less crowded. The space now for one car of the usual size can hold at least three such little cars.
The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour.
The cars of the future will be fine for going around the city, but they will not be useful for going far away. If the car is powered by electricity, it will have two batteries—one battery for the motor and the other for the horn (喇叭), signals (信号灯), etc. Little cars which are powered by gas will go 45 kilometers before needing to stop for more gas.
If big cars are still used along with the small ones, two sets of roads will be needed to set up in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the small, slower ones.
1. What’s the advantage (优势) of the small cars?
A. There won’t be so much pollution and the small cars won’t be so expensive as the big ones.
B. It will be safer to drive these small cars.
C. There will be more space for cars to park.
D. All of the above.
2. Two sets of roads are necessary in the future in order to      .

You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words.
Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(内部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.
Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you’re sitting— it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”
So, what lessons can we learn from this? “ Spend time with happy people— otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”
小题1: According to Hugo Critchley, ________.
A.emotions are as visible as facial expressions
B.we yawn more frequently when we have a cold
C.emotions are connected with states of internal responses
D.the change of blood pressure is not linked with the change of emotions.
小题2:The underlined word “synchronies” in Paragraph 4 means “_____”.
A.move slowlyB.change rapidlyC.relax temporarilyD.respond accordingly
小题3:From the passage we can learn ________.
A.sadness is as contagious as happiness
B.anger is less contagious than friendliness
C.surprise is more contagious than smile
D.surprise is the most contagious among emotions
小题4:Which of the following statements is true according to the passage?
A.Emotions have delicate influence on fellow humans.
B.Children like copying the actions of the fellow humans.
C.Scientists are still confused about contagious yawning
D.People tend to communicate more with body language.

Among various programmes, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style(风格). But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows.
Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as can be. For example, the show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.
Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality(质量) of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show’s main viewers are middleclass Americans. Most of these people have the time, money, and ability to deal with life’s tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to-21-year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show’s exploitation.
小题1: Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey are ____.
A.more interestingB.unusually popularC.more detailedD.more formal
小题2:Though the social problems Jerry Springer talks about appear unpleasant, people who watch the shows____.
A.remain interested in themB.are ready to face up to them
C.remain cold to themD.are willing to get away from them
小题3:Which of the following is likely to be a topic of the Oprah Winfrey show?
A.A new type of robot.B.Nation hatred.
C.Family income planning.D.Street accident.
小题4:We can learn from the passage that the two talk shows_____.
A.have become the only ones of its kind
B.exploit the weaknesses in human nature
C.appear at different times of the day
D.attract different people

Telecommuting(远程办公) will have major effects on the worlds of work and family life. However, its biggest effect will be in the area of individual freedom, responsibility and time management.
Work and workplaces will change greatly. Offices may become smaller, as fewer desks are needed. There will be greater need for high-speed Internet connections to link the office and the home, and even homes to other homes, as other employees also begin working at home. Hours spent in traffic jams, and fights for parking should diminish, as workers travel less.
Family life will also change. Both husbands and wives will be able to arrange their work around family commitments such as taking children to school, cooking, spare time activities, and so on. However, households(家人) will also have to set aside areas for work-particularly if more than one person is telecommuting.
However, although the ideas of more time at home and less time traveling are attractive, there are some drawbacks to telecommuting. People may feel that they cannot escape from work, work longer hours, or become less social. The quality of work may suffer because of fewer face-to-face interactions with other employees, and there may be delays if other workers are not immediately available. Telecommuters may also feel isolated. A major change will be in the way people think about work as a place or an institution. Instead, they will focus on the task or the product. Workers may feel less loyal to a company.
In conclusion, the effects are difficult to predict because they depend on the extent to which telecommuting becomes popular. At the same time, however, telecommuting could be the start of a major societal shift, possibly as big as the Industrial Revolution which created our present ideas of work.
64. This passage was mainly written to tell us _____.
A. about the advantages of telecommuting               
B. how telecommuting will change the world
C. that telecommuting will affect family life            D. how to telecommute in the future
65. What is Paragraph 4 mainly about?
A. The disadvantages of telecommuting.                  B. Setting aside areas for work.
C. The future of telecommuting.                             D. The employees’ focus on work.
66. With telecommuting in the future, which of the following will be reduced?
A. Working hours and family time.                         B. Face-to-face communication.
C. Spare time and individual freedom.                            D. Spending time with friends.
67. What can we infer from the passage?
A. Telecommuting will change the world completely.
B. There will be no traffic jams because of telecommuting.
C. Work efficiency will increase through telecommuting.
D. Telecommuting workers will likely change their jobs.

Eight in 10 Americans eat fast food at least once a month and half eat it every week according, to a Gallup Poll. Yet most people who eat fast food know it’s bad for them. So why do they keep eating it?
The answer is simple: the benefits of eating fast food outweigh the long-term implications for most people. However, once you read these reasons why all those trips to the drive through may be slowly killing you, you may just want to stop eating fast food after all.
1. Fast food makes you fat.
A 15-year study of over 3,000 people found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. You probably know this already. But here’s something you may not know.
2. Fast food is addictive.
The more you eat fast food, the more you crave it. One study found that fast food is “a potentially addictive substance that is most likely to create dependence in vulnerable populations.” If you eat fast food once a week or more, you may be addicted to it.
3. Fast food is affecting your kids.
According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Kids have an amazing ability to recall ads they’ve seen. Fast food marketers know this, and design ads accordingly. Research shows strong associations between increases in advertising for non-nutritious foods and rates of childhood obesity.
4. Fast food “burgers” don’t have much burger in them.
One study found that most fast food burgers are composed of about 50 percent water and the actual meat content is only 2.1 to 14.8 percent. So what makes up the rest of it, you ask? Chemical fillers and preservatives, mostly. That’s why we see read horror stories about burgers that don’t go bad.
5. Even “healthy” fast food isn’t that healthy.
Fast food restaurants are catering to consumer demands to produce healthier options. The problem is, their definition of “healthy” is quite lax. One of the healthiest dishes at Burger King, the Garden Fresh Salad Chicken Caesar with TENDERGRILL Chicken and dressing, still has almost 500 calories and 28 grams of fat, and nearly a day’s worth of sodium.
6. Fast food is inhumane to animals.
Okay, this one may not be a reason why fast is killing you, but it’s still a compelling reason to stop eating fast food. 9 billion animals were slaughtered in the US alone in 2012 and much of that meat is for your fast food burgers and chicken sandwiches. Large factory farms resemble more of a “business” than a “farm.” Animals suffer in crowded spaces where they rarely have access to the outdoors or sunlight. They are pumped full of antibiotics to combat disease, which runs rampant in these conditions. Livestock is one of the biggest sources of pollution and environmental negligence, according to the UN.
7. Fast food sodas are loaded with sugar.
High fructose corn syrup (HFCS) is the cheap sweetener most fast food restaurants use in their sodas, desserts, and many other products. Princeton University researchers linked HFCS consumption to obesity in an animal study. Rats given HFCS gained more weight and body fat than those given table sugar.
小题1:How many factors are mentioned which can account for the reason why fast food is slowly killing you?
A.Seven.B.Three.C.Four.D.Five.
小题2:According to the text, we know that_____.
A.many people keep eating fast food because they know nothing about the harm which fast food will bring them
B.fast food plays a key role in children’s growth
C.eating fast food is connected to weight gain and insulin resistance.
D.many fast food restaurants are can offer a good and healthy meal to consumer
小题3:What is the purpose of the passage?
A.To help us make right decisionsB.To advise us to stop eating fast food
C.To tell us how to keep fitD.To encourage us to be humane to animals
