Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.www.examda.com
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays.
This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.Which of these sentences best describes the writer's point in Paragraph 1?

People used to think that wetlands were wasted land. Developers would drain them with ditches（水沟），fill them in with tons of soil，and build houses，schools，and parking areas on them.Then scientists began to realize the important role wetlands played in the environment.
Wetlands act like giant sponges（海绵） during storms.They soak up extra storm water and afterward release it slowly back into the water cycle.This helps prevent flooding. Towns where people have drained wetlands have found that in a big storm，their streets and homes are often flooded because there are no wetlands to soak up the excess water.
Wetlands also act as giant filters where pollutants are absorbed and dissolved over time.Though wetlands can become polluted from dumping，wastewater，and fertilizer runoff from farm fields，they are able to process some pollutants over time because of all the microorganisms and plants living there.
Wetlands are especially important for providing homes and breeding grounds to millions of birds，fish，and amphibians worldwide. Many wetlands have become national wildlife refuges（避难所），where you can go to take pictures and look at birds and animals.
The Everglades are a huge wetland that once covered more than four million acres of southern Florida. Sometimes called the “river of grass”，the Everglades are a shallow sheet of water that slowly flowed across a grassy plain. In the late 1800s people began draining parts of the Everglades for development. Roads were built and towns sprang up.The Everglades shrank to half its original size. Cities like Miami grew up where once there was a thriving wetland. Sewage and waste from the cities were pumped into the remaining wetlands. Over time scientists began to see the importance of the Everglades. Even with its smaller size，the Everglades filtered the pollutants coming from the cities，absorbing the worst of it like a sewage treatment plant. During storms the Everglades protected the cities from storm surge flooding. They also are just a great place to visit and see wildlife.The first paragraph is intended to tell us________.

ChiChi weighs only 13 pounds. “He’s so tiny，I can carry him with one hand，” says Mary Lane.“Most people see him and think he’s useless.”
But last October，ChiChi proved to be more than just a pretty face. Mary and her husband，Rick，were relaxing on the beach one afternoon while on vacation in North Carolina’s Outer Banks.As usual，ChiChi was lying on his blanket in his own little beach chair.
“We had our noses buried in books，”recalls Rick，“when suddenly the dog became extremely uneasy. His bark was different from anything we had heard before.And he would not let us ignore him.”
ChiChi ran back and forth in front of his chair as if to run down the beach.The Lanes sat up to see two elderly women in the ocean，about 100 yards down the beach and 10 feet off shore.One was on her back，her head under the waves.The other was struggling hard to keep her friend’s head above the surface.
The Lanes rushed across the sand and into the surf. Rick went to the woman in danger of drowning，while Mary held fast on to the other one and pulled her up on the beach.“Then I went back to help Rick，” Mary says.“The sand dropped off steeply，and a riptide(激流)was beating the woman under. She was completely helpless.”
Not getting well from recent knee surgery，the woman had been unable to turn over or push herself up.“Her friend had been in danger too，” Mary says.“The waves were pushing her around. There’s no way she could have held on much longer.”
The women hadn’t called out for help. “They were struggling so hard that there was no time for screaming，” Mary recalls.“But ChiChi had sensed their danger.”
Duty done，ChiChi was back in his chair，asleep，by the time the two women were on dry ground and the Lanes had returned to their blankets.Luckily，the women were fine，though shaken.They thanked the Lanes for saving their lives.

Researchers at the University of Kansas say that people can accurately judge 90 percent of a stranger's personality simply by looking at the person’s shoes．“Shoes convey useful information about their wearers，’’the authors wrote in the new study published in the Journal of Research in Personality．
Lead researcher Omri Gillath said the judgments were based on the style，cost，color and condition of someone’s shoes．In the study，63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants．Volunteers in the study were photographed in their most commonly worn shoes，and then filled out a personality questionnaire．
Some of the results were expected：People with higher incomes most commonly wore expensive shoes，and flashier shoes were typically worn by outgoing people．However，some of the more specific results are strange enough．For example，“practical and functional’’ shoes were generally worn by more “pleasant" people，while ankle boots were more linked with ‘‘aggressive’’ personalities．The strangest of all may be that those who wore ‘‘uncomfortable looking” shoes tend to have “calm” personalities．And if you have several pairs of new shoes or take extreme care of them，you may suffer from “attachment anxiety"，spending lots of time worrying about what other people think of your appearance．There was even a political calculation in the mix with more liberal(主张变革的)types wearing “shabbier and less expensive” shoes．
The researchers noted that some people will choose shoe styles to mask their actual personalities，but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities．What does this text mainly tell us?
| A．The richer you are , the more expensive shoes you will wear. |
| B．Shoes convey false information about the wearer． |
| C．People’s personalities can be judged by their shoes． |
| D．People know little about their personalities． |
Which of the results is beyond people’s expectations?
| A．Wealthy people often wear expensive shoes． |
| B．Pleasant people like wearing uncomfortable shoes． |
| C．Aggressive people are likely to wear ankle boots． |
| D．Flashier shoes are typically worn by outgoing people． |
People suffering from“attachment anxiety” tend to
| A．wear strange shoes |
| B．worry about their appearance |
| C．have a calm character |
| D．become a political leader |
The author wrote the text in order to
| A．inform us of a new study |
| B．introduce a research method |
| C．teach how to choose shoes |
| D．describe different personalities |

Pierre is a 25-year-old penguin at the California Academy of Sciences．Due to his old age，he was going bald，which made him feel too cold to swim in the pool．Therefore，biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool．
Unlike marine(海生的) mammals，which have a layer of blubber(鲸脂) to keep them warm，penguins depend on their waterproof feathers．Without them，Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water．
“He was cold：he would shake，”said Pam Schaller，a senior biologist．Schaller first tried a heat lamp to keep Pierre warm．Then she got another idea：if wetsuits keep humans warm in the cold Pacific，why not make one for Pierre?
Schaller designed the suit，which covered Pierre’s body and had small openings for his flippers．
“I would walk behind him and look at where there were any gaps．and cut and refit until it looked like it was extremely suitable．”she said．
One concern was that the other penguins would reject Pierre in his new suit，but in fact，they accepted his new look．He swam freely and got along with others well，although he was the only penguin with a black stomach．
Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers，but” certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable”．
Pierre will take off his suit after his new feathers grow back．Pierre felt too cold to swim in the pool because of____．
| A．not having a layer of blubber |
| B．having few feathers due to old age |
| C．having no wetsuit |
| D．others penguins rejecting him |
The idea of making a wetsuit for Pierre came from__________.
| A．total invention | B．the use of wetsuit on humans |
| C．the use of heat lamp | D．waterproof feathers． |
Schaller followed Pierre in order to see____________________．
| A．whether other penguins would reject him |
| B．if anywhere of wetsuit needed to be cut and refit |
| C．if the wetsuit kept warm |
| D．whether the wetsuit would keep the feathers from recovering |
The best title of the passage is____．
| A．Wetsuit for An old Penguin | B．Old Penguin Getting Bald |
| C．Unwilling to Swim | D．Strange Look of Pierre |
