Tiny transmitters(發(fā)射機(jī)) fixed on the backs of the blue-green bees have allowed scientists to follow the insects as they fly for miles in search of rare flowers.

Working in Panama,scientists caught 17 bees of the common species and fixed a 300 milligram radio light onto the back of each.The signals they sent out were used to follow their movements in and around the forest where they lived.

Professor Martin,from Princeton University,US,and the Max Planck Institute for Ornithology in Germany,said,“By following the radio signals,we discovered that male bees spent most of their time in small centre areas,but could take off and visit areas farther away.One male even crossed over the shipping lanes in the Panama Canal,flying at least 5km,and returned a few days later.”

Researchers have struggled to follow the movements of bees before,following bees marked with paint or using radar which doesn’t work well in forests.

“Carrying the transmitter could reduce the distance that the bees travel,but even if the flight distances we record are the shortest distances that these bees can fly,they are impressive,long-distance movements,” said Dr.Roland Kays,from New York State Museum,a co-author of the research published today in the on-line journal.“This result helps to explain how these bees’ pollination(授粉) can be so rare.” Pollination by bees and other insects is the key to the diversity and continued growth of flowers and trees in some forests.

The new study is the first to use radio transmitters to follow bees in a forest.Similar research may now be carried in temperate forests,where bees also play a vital role.

1.The main purpose of the passage is to___

A. call on people to protect the bees for the environment

B. explain why the bees fly far away in search of flowers

C. introduce a modern way to follow the bees to readers

D. encourage the public to support the scientists' research

2.What was the problem when researchers tried to follow the bees in the past?

A. It was quite difficult to mark the bees

B. The radar itself didn't work very well

C. The bees weren't easy to be recognized

D. Environmental limits were hard to solve

3.What Dr.Roland Kays said implied that____

A. he didn't expect bees could fly so long a distance

B. The transmitter didn't have any effects on bees at all

C. He wanted to know how far bees could travel badly

D. The record was in fact as exact as he had thought

4.Researchers follow the movements of bees mainly to___

A. learn how far they can fly at most

B. discover how they affect the plants

C. correct some wrong ideas about bees

D. get to know where they enjoy living

What are American high schools like? Well, I’m happy to tell you what I know.

When I started school here, it had already been a week since the school opened. At this school, freshmen usually go on a trip for about three days at the beginning of school. Unfortunately I missed that wonderful trip, which would have been the best time to get to know my classmates. I was really sad. I wished I’d known about it earlier.

Despite the disappointment, however, I gradually adapted to my new life and school.

There is a space in the basement of the teaching building where students chat and meet each other. As we do not always have the same classrooms and classmates, the school wants us to get to know each other there. Students usually come to school early, sit in that space and have fun. Around the space, there are many lockers for students to leave their books in, so that students do not have to carry a heavy schoolbag everywhere.

It really surprises me that we have almost no textbooks. We only have textbooks for World History and Algebra 2 and they are big and heavy, like bricks. For other classes, we only need binders (活頁(yè)夾) with paper in them. Without textbooks, students learn things freely and actively. For example, my humanities teacher just teaches us what is in her mind at the time. We never know what we will learn.

Another difference between American schools and Chinese schools is that American schools care about students’ morality more than their academic studies. For example, if you do not finish your homework, you will just be asked to do it later, but if you cheat or lie, you will get a warning or even be kicked out.

I think that most students here are good at schoolwork as well, but compared to Chinese students, they can make learning a more joyful experience. I think we should take the good points from our two different kinds of education to perfect our approach to studying.

1.What was the writer sad for?

A. He was late for school.

B. He missed the trip at the beginning of school.

C. He didn’t know anyone.

D. American students looked down upon him.

2.Why do students go to the basement of the teaching building?

A. To attend class. B. To share a classroom.

C. To have fun. D. To meet teachers.

3.How do teachers in the US teach the students?

A. However they want to.

B. They use bricks.

C. Some use textbooks; some teach freely.

D. They always teach as required.

4.According to the passage, in American high schools, ________.

A. you are likely to be kicked out if you cheat

B. you’ll be punished if you do not finish your homework

C. students are better at school work than Chinese students

D. students care much about the grades they get

Directions:Read the following three 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.

Friends and fellow citizens:I stand before you tonight under accusation of the unproven crime of having voted at the last presidential election, without having a lawful right to vote.It shall be my work this evening to prove to you that in thus voting, I not only committed no crime, but, instead, simply exercised my citizen's rights, guaranteed to me and all United States citizens by the National Constitution(憲法), beyond the power of any state to deny.
Our democratic-republican government is based on the idea of the natural right of every individual member to a voice and a vote in making and executing the laws.We declare the duty of government to be to secure the people in the enjoyment of their unchallengeable right.We throw to the winds the belief that government can give right.
‘All men are created equal, and gifted by their Creator with certain undeniable rights.Among these are life, liberty, and the pursuit of happiness.To secure these, governments are established among men, gaining their just powers from the agreement of the governed.’
Here is no shadow of government authority over rights, or exclusion of any class from their full and equal enjoyment.Here is pronounced the right of all men, and ‘therefore,’ as the Quaker minister said, ‘of all women,’ to a voice in the government.And here, in this first paragraph of the Declaration, is the declaration of the natural right of all to the vote; for how can ‘the agreement of the governed’ be given, if the right to vote be denied?
The introduction of the Federal(聯(lián)邦的) Constitution says: ‘We, the people of the United States, in order to form a more perfect union, establish justice, insure domestic peacefulness, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity(子嗣), do establish this Constitution for the United States of America.’
It was we, the people; not we, the white male citizens; not we, the male citizens; but we, the whole people, who formed the Union.And we formed it, not to give the blessings of liberty, but to secure them; not to the half of ourselves and the half of our posterity, but to the whole people - women as well as men.And it is absolute ridicule to talk to women of their enjoyment of the blessings of liberty while they are denied the use of the only means of securing them provided by this democratic-republican government - the vote.
1.The speaker was standing in front of the audience to ________.
A. accuse the government of having denied treating her unfairly
B. fight for the legal right to vote in the United States as a woman
C. share a recent victory on voting for the president of the States
D. guarantee that they could better understand the National Constitution
2.The expression ‘throw to the winds’ (Paragraph 2) is closest in meaning to ‘________’.
A. abandon
B. emphasize
C. shake
D. spread
3.Which of the following statements is true according to the speech?
A. The Quaker minister holds conflicting opinions on women’s right to vote.
B. Government authority has the right to bar some of the governed out of liberty.
C. The policy is undeniably adopted that all the governed in America have the equal rights.
D. There’s no way to the real agreement of the governed if women’s vote right is robbed.
4.It can be inferred from the speech that ________.
A. it’s more important to have liberty than have good wishes of it
B. the Federal Constitution comes from the National Constitution
C. it’s ridiculous that women enjoy liberty while their rights are not secured
D. racial and gender issues are among the major social problems of the USA
5.Which of the following might be the best title of the speech?
A. For the Sake of Liberty and Happiness
B. Vote on the Women’s Rights
C. In the Name of Equal Right to vote
D. Power of American Constitution

There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

I’ll never lose weight --- I come from a fat family

Wrong! While we can’t change the body type we are born with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.

I am fat because I burn calories slowly

Wrong! Fatness is not caused by a slow metabolism(新陳代謝). If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.

Exercise is boring

Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that’s fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set a distance or time challenge.

No pain, no gain.

Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but when your body adapts to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.

1.What does the author think about being fat?

A.It is the family genes that make people fat.

B.People are fat because they consume too little energy.

C.It is the consequence of people’s unbalanced lifestyle.

D.A diary of exercise can prevent people from becoming fat.

2.According to the author, how can we make exercise more interesting?

A.By taking varied exercise.

B.By choosing simple exercise.

C.By doing regular exercise.

D.By sticking to outdoor exercise.

3.What is the author’s opinion about “No pain, no gain” in exercising?

A.Exercise should be stopped if continuous pain is felt.

B.Keeping fit is essentially a painful experience.

C.Pain in exercise is a precondition for reaching your goal.

D.Getting used to pain leads to positive changes in your body.

4.What is the purpose of the passage?

A.To argue the importance of keeping fit.

B.To prove some medical facts about being fat and doing exercise.

C.To confirm what has long been believed about keeping fit.

D.To inform readers of some misunderstandings about fatness and exercise.
