IT'S a mystery that has puzzled scientists. Five years ago, researchers found an area in the Atlantic Ocean seabed, where a part of the Earth's outer layer, or crust（地壳）, is　 missing. A thick layer of dark green rock, which is usually found deep inside the planet, lies exposed.

The crust, mantle(地幔) and core（地核） are the main layers that make up the planet. The mantle rests between the crust and the core.

Last month, a team of 12 British scientists set off on a six-week trip to study the hole in the crust.

The hole is about 4,800 meters below sea level and is believed to be more than 48,000 meters long and more than 48,000 meters wide. Scientists think that there are other nearby gaps. "It is like a window into the interior (内部) of the Earth," says scientist　　 Bramley Murton, who is part of the research team.

The site where the hole is located is part of a ridge (山脉) of undersea volcanoes.　 There, two of the plates that make up the Earth's surface meet. The plates are always　　 moving. When the plates move away from each other, lava rushes up from the mantle to　　 fill the gap and form a new crust. But this did not happen in the area where the hole is located.

The hole is giving researchers a good opportunity to study what's below the Earth's　　 surface. The team will use a special robotic tool to film the area and get samples of the exposed mantle. They hope to study everything from the chemistry of the oceans to how the Earth's surface behaves under the sea.

1. What's the title for the passage?

A. How to study the earth.

B. The formation of the earth.

C. A hole in the earth.

D. Studying the inside of the earth.

2.For the main layers of the earth, which one is right?

A. crust, mantle, core　　　　 B. seabed, crust, mantle

C. seabed, mantle, core　　　 D. crust, seabed, core

3.How does the hole come into being?

A. It's because of a volcano eruption.

B. It's because of the plates movements

C. It's because lava rushes up from the mantle

D. It's not clear from the passage.

4.By studying the hole, the scientists want to do the following except____.

A. knowing what's below the Earth's surface

B. getting samples of the exposed mantle

C. getting the film of the hole

D. studying the chemistry of the oceans

Play is the basic business of childhood, and in recent years more and more research has shown the great importance of play in the development of a human being. From earliest  infancy （婴儿）, every child needs opportunity and the right material for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and assist play. To succeed in this, they must be good toys, which children will play with often and will come back to again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.

In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited(遗传的) abilities, is largely determined in the first three years of his life. So a baby's ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.

The next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws and construction toys; painting, scribbling(乱涂) and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others．

By the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys.

Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books and school become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed —to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.

1.The writer wants us to understand that a child_______.

A．cannot grow up without toys               B．matures（使成熟） through play

C．uses toys as friends                      D．has to be taught how to play

2.According to the passage, the abilities a child has inherited from his parents ________.

A．determine his character

B．will not change after the age of three

C．partly determine the standard he is likely to reach

D．to a large extent determine the choice of toys

3.The passage tells us that children are the most curious when they are about______.

A．two years old      B．one year old       C．six years old       D．four years old

4.The article is about_______.

A．the importance of play

B．the importance of books

C．the relationship between play and work

D．children’s speech development

Four habits of happy people

While the recent research has shown that about 60 percent of our baseline (基本) level of happiness is probably genetically determined, it means 40 percent is under our control. You can’t go back and get new genes.1.. Here are the good habits of happy people.

·Spend time outside. If you can clock 20 minutes a day outside, studies show you’ll not only maintain a better mood, but your mind will be more open and you’ll improve your working memory. 2..

·Exercise regularly. All exercise releases endorphins (脑内肽) in your brain, and if you work out regularly, this mood boosts（增强）even carries over to non-workout days.3.. Mood stays about the same on days they don’t.

4.. A study has confirmed that when people actively try to be happy, they raise their baseline moods, making them feel happier than those who do not try. In the study, two sets of participants listened to “happy” music. Those who actively tried to feel happier reported the highest level of positive mood afterwards.

·Care for others. 5.. Volunteer work is good for both mental and physical health. People of all ages who volunteer are happier and experience better physical health and less depression.

A. Exercise is easy to do.

B. Put effort into being happy.

C. People around you impact your mood.

D. Sunshine and fresh air make you feel good too.

E. But you can start a good morning over with a new attitude.

F. People who spend time every month helping others are happier.

G. On exercise days, people’s mood is significantly improved after exercising.

A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度） of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

1.Why do yellow taxis result in fewer accidents?

A. Because yellow signals a warning of danger.

B. Because yellow can be seen more easily.

C. Because drivers tend to he more careful in yellow taxis.

D. Because people act more quickly in yellow surroundings.

2.What’ s Prof Ho’s study based on?

A. Physical risks taxi passengers experience.

B. The economic effect of changing taxi color.

C. Personal reports from taxi drivers worldwide.

D. Data from Singapore's largest taxi company.

3.What do Prof Ho’s words in the last paragraph suggest?

A. School buses should be painted yellow.

B. Their findings are worth popularizing.

C. Their study will be furthered.

D. Yellow should be widely used in public transport,

4.What can be the best title for the text?

A. Safer to ride in yellow taxis　　 B. Caution: yellow taxis ahead

C. Why are yellow Taxis preferred?　　 D. How can colors help prevent accidents?

A tender woman, or an independent one, which one would you prefer? A recent research shows that most people would choose the latter.

While proudly reading my words on the report, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced towards my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”

Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quiet! How could I know that she meant that George Washington?

Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

1.What did the author’s classmates think about his report?

A.Controversial. B.Boring.

C.Ridiculous. D.Puzzling.

2.Why was the author confused about the task?

A.He was unfamiliar with American history.

B.He followed the advice and flipped a coin.

C.He forgot his teacher’s instruction.

D.He was new at the school.

3.The underlined word “burning” in Para. 3 probably means _______.

A.annoyed B.ashamed

C.ready D.eager

4.In the end, the author turned things around _______.

A.by redoing his task B.through his own efforts

C.with the help of his grandfather D.under the guidance of his headmaster

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize.

Kristy Vanmarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants（婴儿）are able to quantify substances（物质）—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food.

With the assistance of her team researchers, Vanmarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount.

“Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” Vanmarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.”

“This information further refutes（驳斥）the long-held idea that babies know nothing of the world,” Vanmarle said.

“Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” Vanmarle said.

In the future, Vanmarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study.

1. The quantifying ability refers to the ability to ________.

A. choose between different substances  B. describe the quantity of something

C. get much knowledge of the world    D. obtain math-related skills

2. What is mainly talked about in Paragraph 4?

A. The process of doing research.   B. The final choice of infants.

C. The scientific findings.         D. The observation of infants’ behavior.

3. Babies choose the larger amount of food ________.

A. through their natural abilities  B. with the help of parents

C. on personal preference           D. by saying numbers

4.We can learn from the text that ________.

A. some parents don’t care about their kids

B. scholars disagree on baby-training programs

C. little research has been done on infants

D. people used to think the world is known to babies

5.What’s the best title of the text?

A. Unique Quantifying Methods   B. Amazing Baby-training Ideas

C. Early Human Abilities         D. Breakthrough in Baby Studies

A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

Avoiding temptation (诱惑) is an effective method for maintaining self-control, which is called the "out of sight, out of mind" principle. One recent study, for instance, found office workers less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don't believe that one's willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower-at least to a point.

Willpower may also be made less vulnerable (脆弱) to being exhausted in the first place.

Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year's Eve is the worst possible approach. Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don't try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you'll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won't require making decisions at all.

1.From the studies in the passage we learn that ________.

A.people have unlimited self-control B.high motivation ensures one's success

C.too many temptations often lead to failure D.willpower is hardly completely exhausted

2.The underlined phrase "tap into" in Paragraph 3 most probably means ________.

A.put up with B.make up for

C.make use of D.keep away from

3.The author compares self—control to muscles ________.

A.to explain the benefits of practicing self-control

B.to show the significance of regular exercise

C.to argue that self-control can he easily used up

D.to prove the long-term effect of willpower

4.To develop a good habit, which of the following does the author prefer?

A."I will give up dessert and do exercise."

B."I will set three goals this new semester."

C."I will read an English novel every month."

D."I will keep myself from any temptation."
