第一节（共15小题；每小题2分，满分30分）
It was getting dark when Lisa was returning from teaching out in a small community. She’d been traveling the same route for over a year and there was seldom traffic on this highway.
Lisa remembered back to her previous experiences. In those days she was constantly picking up strangers on the road. Her family became greatly concerned about her safety, but she continued the practice until the day her sister told her that one of her friends had been shot by a hitchhiker (搭便车者). That was when the family heard the promise, “No more hitchhikers, I promise!”
When she thought back to these things, she suddenly noticed that a car was parked on the road ahead. Then she saw a man waving. He was in trouble, she thought. But suddenly she remembered the promise. She knew this road well and the chances of another car coming along to help were very little. Now as the man ran toward her car she shook with fear, and didn’t know if he was truly in need. She could not leave him here in this storm. The stranger explained that his car was broken. She knew she had to break the promise. She told him to get in. They drove for an hour into the next city and she took him to a telephone box. She waited until he had made a call. When he reported back to her that a family member would soon be there for him, she wished him well and left.
Tears fell on her cheeks as she drove away. It felt as though she had been holding her breath for an hour. “I hope they’ll understand why I had to break my promise.”
56. We can learn from the text that Lisa promised______.
A. not to pick up free riders on her way home
B. not to drive home alone when it was late
C. to help those whose cars were broken
D. to learn from the friend of her sister’s
57. Which of the following can best describe Lisa?
A. Careful and serious B. Faithful and clever
C. Kind and helpful D. Brave and patient
58. What was Lisa’s attitude toward her breaking the promise?
A. It was very serious.
B. It should be forgiven
C. She was too nervous to go home.
D. She felt regretful about her mistakes.
59. What would be the best title for the text?
A. Lisa’s adventureB. An unusual travel
C. Strangers’ kindness D. The broken promise

What would you do if you were lost in the dark forest at night? The first sensible lesson is that you shouldn’t bother trying to find your way in the dark at all, but just stay put until dawn. Because then you won’t trip over things? No, mainly because you’ll have an idea of direction. The sun rises in the east. But you will be amazed at how many people forget they know that. Apparently, the area underneath a holly bush provides a good makeshift shelter — they are thick, and evergreen. The next thing to do — or rather not to do — is panic, for the obvious reason that unless there is someone there to hear you scream, it will get you nowhere. Just try to think of nice, happy things.
There is always a point in films when a person who is lost in the desert or the snow, dehydrated(脱水的) and exhausted, comes across a set of their own footprints and realizes they have just walked in a huge, round circle. It is wrong to owe it to the unequal strengths or different lengths of your legs. Experiments prove that, without the sun or the moon (or landmarks) as a fixed guide, lots of small errors add up over time so the brain can’t correctly identify the “straight ahead” direction. To just get out of somewhere, pick a spot on the horizon and just head for it.
There are several ways to find directions in the dark, and by far the best is to establish north using the stars. Most people can identify the Plough, which is part of Ursa Major. It looks a lot like a saucepan. The Plough rotates through the sky, but let’s imagine the saucepan lying horizontally (水平地), with its handle on the left. You need to trace a line from the star at the right-hand base of the pan, through the star at the right-hand rim (边沿), and follow it upwards; the north star is roughly five times the distance between those two “pointer” stars. Then drop a vertical line from the North Star to the horizon and that’s north.
“Tonight is very cloudy and I can’t see the Plough.” Maybe luckily, it is quite windy. Keep in mind that almost all of our weather comes from a south-westerly direction. (This only works if you are in the British Isles). To find the direction, you can throw light bits of dried-out grass in the air and see which way they blow; or, if there are clouds and patches of clear sky, see which way they blow across the stars. You can also get an idea of direction from leggy plants. If they look as if they have been blown over, they will probably be pointing north-east. If they are simply leaning in one direction as they grow, there’s a good chance that is south (they will be reaching towards the sun). The last thing to do is to judge your direction and off you go.
68. What might be the best title of the passage ?
A. How to survive in the forest B. How to protect yourself in the forest
C. How to direct your way out of the wild D. What to do if you are lost
69. Which of the following pictures matches the description of the position of the north star?

70. Why will people often walk in a circle if they are lost in the desert or the snow?
A. Because without anything to refer to for directions, the brain will be confused by errors.
B. Because one of the legs is longer and stronger than the other.
C. Because the desert or the snow usually covers a large area for people to get across.
D. Because people usually feel dehydrated and exhausted in the desert or the snow.

A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth.
Until now, it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience — what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）.
But in the new study, researchers describe a method for improving this skill, along with experiments to prove it works.
The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence, so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
First they measured the fluid intelligence of four groups of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game, in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items, monitor ongoing performance, manage two tasks at the same time and connect related items to one another in space and time.
The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively. To make sure they were not just improving their test-taking skills, the researchers compared them with control groups that took the tests without the training.
The results, published Monday in The Proceedings of the National Academy of Sciences, were striking. Improvement in the trained groups was a lot greater. Moreover, the longer they trained, the higher their scores were. All performers, from the weakest to the strongest, showed significant improvement.
“Our results show you can increase your intelligence with proper training.” said Dr Jaeggi, a co-author of the paper. No one knows how long the gains will last after training stops, he added, and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.
64. The researchers thought the key to improving the intelligence was______.
A. memorizing telephone numbers B. improving working memory
C. training in concentration D. recalling a card
65. The following aspects of the training help increase intelligence Except_______.
A. ignoring irrelevant items B. monitoring ongoing performance
C. managing two tasks at the same time D. using previous experience
66. When the experiment was conducted, the researchers ______.
A. trained the four groups for the same period of time
B. only made comparisons between the four groups
C. compared the four groups with control groups D. trained the four groups together
67. By writing the article, the writer intends to_____.
A. inform the readers of a new study
B. call on people to be trained to increase intelligence
C. prove one’s born brainpower can be improved
D. tell people the improved intelligence will last forever

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。
IN a surprising discovery about where higher life can survive, scientists have found a shrimp-like creature and a jellyfish (水母) swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly (下腹部) of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.
“We were operating on the presumption (假定) that nothing’s there,” said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂热的) over it,” he said of the 7.5cm long, orange creature starring in their two-minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod (片脚类动物), which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh (苛刻的) environments. And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis-Evans, a scientist of the British Antarctic Survey called the finding intriguing (吸引人的). He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20cm-wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small of an area, she said.
Yet scientists were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t, Kim said.
So how do they survive? That’s the key question, Kim said.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything,” Kim said.

A. jellyfish B. mammal C. microbes D. shrimp-like creature
57. According to Kim, the shrimp-like creature ______.
A. swam great distances to Antarctic B. has always lived in the region

A. it marks NASA’s first Antarctic biological study
B. it proves there is marine life in the Antarctic
C. it could inspire further study of life in harsh environment
D. it shows that Lyssianasid amphipod is closely related to shrimp
59. The last three paragraphs suggest that ______.
A. researchers will look at the places the creatures came from
B. ice scientists will drill deeper to find more creature
C. scientists know very little about the planet they live on
D. further research will be done about what the creatures live on
