As they migrate（迁移) , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.
To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate. Many migrating birds do the same thing.
The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops. What's the main idea of the text?

They travel in groups, noses just inches away form GPS screen. Suddenly a boy shouts “I found it!”, grinning and walking away from the group.
The others focus on their screens. “Me. too!” shouts another a moment later, until all six kids are crowded around a tree, pulling out a plastic bottle painted to look like tree bark. It doesn’t seem like much from the outside, but everyone gathers around, eager to see what’s inside.
This is geocaching, a high-tech game played using coordinates (坐标) and global positioning systems to find hidden “treasures”.
It’s open to anyone—hiders or seekers—with a GPS and access to www.geocaching.com, where more than half a million users download and upload the coordinates of nearly 1 million hidden caches (储藏物) and write about their experiences in this worldwide hunt.
Although some adventures can take hours or even days, the contents inside the actual cache usually aren’t valuable—often just a book or a small trinket (小饰品).
But participants aren’t in it for the treasure. They say it’s a great way to exercise. Or it brings them to remote destinations or historical sites. Some consider it an extreme sport, looking for geocaches hidden in mountains or in other nearly inaccessible locations.
Jeffrey Howe, 41, sees it as an opportunity to take kids on adventures to unfamiliar places. The youths at the shelter mostly come form the city, but geocaching has taken them to parks, the suburbs, and, once, to a 498-meter-high mountain.
“Geocaching is a way to give kids the idea that there’s a whole world out there other than what they know from their home neighborhoods and video games,” he said.
How does it work? Log onto the Website and enter your zip code (邮编), then search for caches near your location. Although posted coordinates will take a GPS within about 4.5 meters of a cache, a good hide will require seekers to do a bit of hunting around. Caches can’t be buried underground, nor can they be hidden on private property (财产), in dangerous locations or in some national parks.
Posts written about the find—whether successful or unsuccessful—are an important part of the game, with users proudly recording the places to which they’ve traveled.

The British royal family is about to be slimmed down. The Queen plans to reduce the number of real royals, it was recently announced. However, there seems little sign of the monarchy (君主) disappearing completely.
Up till the 17th century, the British king or queen was believed to rule by “divine (神的) right”, which was the idea that God chose the king or queen to rule and that he or she was therefore above the law. However, this idea ended with the English Revolution, in which King Charles I was imprisoned and then beheaded (斩首) in 1649.
So what role does the British royal family have today?
Well, the Queen has important formal duties as Head of State, the Queen represents the UK on visits abroad and invites other world leaders to visit the UK. As Head of the Armed Forces: Only the Queen can declare when the UK is at war or when war is over. The Queen also has constitutional duties: She has to sign many government and Commonwealth (英联邦) documents everyday.
In addition, the royal family sends a great deal of its time traveling up and down the country in support of different charity projects.
But republicans in Britain do not believe there should be a royal family. Sometimes, the press and media criticize the royal family as well. One criticism is that British people should have to pay for the royal family through their taxes.
Today, the royal family works hard to be relevant(相关联的) in the modern world. The Queen Speech on television is less formal every Christmas, and is now available as a podcast (播客). In 2005, after graduating from university, Prince William spent time teaching English in Uruguay, the sort of work many young British people do at some time in their lives.
1. What can be concluded from the first two paragraphs?
A. The British King or Queen is now considered above the law.
B. The British King or Queen is no longer believed to rule by divine right.
C. The royal family played a less important role in Britain in the late 17th century than in nowadays.
D. The English Revolution put an end to the British royal family in 1649.
2. Which of the following is NOT among formal duties of the Queen?
A. Traveling around the UK.
B. Declaring when the UK is at war.
C. Inviting other leaders to visit the UK.
D. Signing Commonwealth documents every day.
3. With the example of Prince William in the last paragraph, the author intends to show _____.
A. Prince William is very popular in the UK
B. the royal family is trying to connect better with ordinary people
C. Prince William has made an effort to win young people’s admiration
D. many young British people do voluntary work
4. According to the article, British people __________.
A. are all in favor of the royal family
B. can talk to the Queen through a podcast
C. pay for the royal family through the taxes
D. criticize the royal family through media and press

Section B
Directions: Read the following four passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
The professor stood before his class of 30 senior molecular (分子) biology students, about to pass out the final exam. “I have been honored to be your instructor this semester, and I know how hard you have all worked to prepare for this test,” he said to them. “I am well aware of how much pressure you are under to keep your GPAs (平均成绩) up, and because I know your are all capable of understanding this material, I am prepared to offer an automatic “B” to anyone who would prefer not to take the final.”
The relief was audible as a number of students jumped up to thank the professor and left the class. The professor looked at the handful of students who remained, and offered again, “Any other takers? This is your last opportunity.” One more student decided to go.
There were seventeen students left. The professor closed the door and took attendance. Then he handed out the final exam.
There were two sentences typed on the paper: “Congratulations, you have just received an ‘A’ in this class. Keep believing in yourself!”
I never had a professor who gave a test like that. It’s a test that any teacher in any course could and should give. Students who don’t have confidence in what they’ve learned are “B” students at best.
The same is true for students of real life. The “A” students are those who believe in what they’re doing because they’ve learned from both successes and failures. They’ve absorbed life’s lessons, whether from formal education or the school of hard knocks, and become better people.
Don’t let the biggest limit be yourself.

D. he intended to tell the students about the importance of confidence
2. Which of the following statements is TRUE according to the passage?

C. There were no problems on the test paper for the students to work out.
D. The way the professor tested the students would be unsuitable for other subjects.
3. According to the author, the test given by the professor is ________.
A. funny B. instructive C. confusing D. inappropriate

If women are mercilessly exploited year after year, they have only themselves to blame because they tremble at the thought of being seen in public in clothes that are out of fashion; they are always taken advantage of by the designers and big stores. Clothes which have been worn only a few times have to be put aside because of the change of fashion. Women usually stand in front of a wardrobe full of clothes, announcing sadly that she has nothing to wear.
Changing fashions are nothing more than the international creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women , who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on.
No one can claim that fashion industry contributes anything really important to society. Fashion designers are rarely concerned with vital thing like warmth, comfort and durability（持久性）. They are only interested in outward appearance and they take advantage of the fact women will put up with any amount of discomfort, as long as they look right. There can hardly be a man who hasn’t at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or deliberately picking her way through deep snow in high-heeled shoes.
When comparing men and women in the matter of fashion, the conclusion to be drawn are obvious. Do the constantly changing fashions of women’s clothes, one wonders, reflect qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers. Do their unchanging styles of dress reflect basic qualities of stability and reliability? That is for you to decide.
