       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.

    A recent report on online education, made by SRI International for the Department of Education, has a serious academic (学术的) title, but a most interesting conclusion: “ Students in online learning conditions performed better than those receiving face-to-face instruction.”
    The report examined the research on online and traditional classroom teaching from 1996 to 2008. Some of it was in K-12 settings, but most of the studies were in colleges and adult continuing education programs.
    Over the 12 years, the report found 99 studies in which there were comparisons of online and classroom performance for the same courses. The result of the Department of Education’ s research showed that usually, students doing some or all of the course online would rank a little higher than the classroom students with little but meaningful difference.
    “The importance of the study lies in showing that online learning today is not just better than nothing — it actually tends to be better than traditional instruction.” said Barbara Means, the study’ s lead author and an educational psychologist at SRI International.
    This hardly means that we’ll be saying goodbye to classrooms. But the report does suggest that online education could be set to develop sharply over the next few years.
    Until fairly recently, online education totaled to little. That has really changed with the arrival of webbased video, instant (即时的) messaging and teamwork tools.
    The real promise of online education, experts say, is providing learning experiences that are more suitable for individual (个体的) students than is possible in classrooms. That allows more “learning by doing,” which many students find more attractive and useful.
    “We are at a turning point in online education,” said Philip R. Regier, the leader of Arizona State University’ s Online and Extended Campus program.
    The biggest near-term growth, Mr. Regier predicts, will be in continuing education programs.
    小题1:What do we know from the passage?
    Most of the studies were done in high schools.
    The report was based on more than 100 studies.
    The studies were carried out for more than 20 years.
    The difference between online and traditional teaching is not big.
    小题2:We can learn from the passage that __________.
    traditional education will come to an end
    traditional education is not popular any longer
    online education didn’ t develop rapidly until recently
    middle schools are facing the choice between online and traditional teaching
    小题3:Which is NOT the reason why many students prefer online learning?
    Online teaching is more suitable for individuals.
    Classroom teaching is not practical and useful.
    Students can learn by doing in online courses.
    Online teaching is more interesting.
    小题4:Which do you think is the best title for the passage?
    Study finds that online education beats the classroom
    Why is online education on the rise?
    A report on online education
    Classroom teaching is out

    People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe . In the late 1800s, the Turks made cigarettes popular.
    Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person’s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
    Nicotine can make new smokers feel dizzy(头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers’ risk of heart disease and stroke.
    Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.

    Will Nanfang University of Science and Technology in Shenzhen announce a new beginning for China’s higher education reform? It’s too early to answer. But its presence is challenging the Ministry of Education. Even without the approval of the ministry it seems that the school is determined to move forward and enroll(招收)50 students, so-called child prodigies(奇才), to begin classes on March l, 2011.On graduating in 2015, these students will receive a diploma unauthorized by the Ministry of Education-unlike the students of their age from the state-run universities.
    The school is committed to modeling itself on Hong Kong University of Science and Technology, but if the government will not approve the school, the situation could cause a lot of trouble for those 50 students if they want to do graduate studies at other higher learning institutions. Other schools could turn their applications down for their unauthorized diplomas.
    The difficulties, however, have not frightened students and their parents away. On Dec.18, 2010 more than 1,000 students and their parents visited Nanfang University of Science and Technology for interviews.
    Private investment marks the school out from other higher learning institutions in the nation. Not a penny comes from the government. So the government will have no voice in how the school will be run.
    The Ministry of Education has published a comprehensive plan for education reform and development between 2011 and 2020.The goal is to make China’s higher education internationally competitive. To accomplish this goal, the government should have the courage to let the educators who have big ideas try them out. The ministry should have applauded the independence the school in Shenzhen has shown and encouraged more to do likewise.
    Education reform in China has reached a new and crucial stage. Nanfang University of Science and Technology has a long way to go to prove itself competitive rather than a diploma mill.
    小题1: What will makes those 50 students different from others?
    A．They are all child prodigies.
    B．They will study much longer time.
    C．They are willing to challenge the Ministry of Education.
    D．They will receive an unauthorized diploma.
    小题2: Over 1,000 students and parents visited the school because            .
    A．they believe that the school will have a bright future
    B．they believe the government is sure to approve the school
    C．the school models itself on Hong Kong University successfully
    D．they will never do graduate studies at other higher learning institutions
    小题3:The trouble the students in the school may have is that            .
    A．the government will have no voice in the school
    B．they won’t receive any diploma when graduating from the school
    C．other schools are unlikely to accept their diploma from the school
    D．they will not learn how to be competitive
    小题4: What does the author think of Nanfang University of Science and Technology?
    A．It is another kind of diploma mill.
    B．It’s impossible for the school to be competitive.
    C．It will never get the approval from the Ministry of Education.
    D．Its independence from the government may benefit the education reform.
    小题5:What is the best title of the passage?
    A．University of New Style.B．China’s Education Reform.
    C．Modeling Hong Kong University.D．Authorized or Not?

    Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the mail carrier, brings mail to a large office building in Washington D.C. He is one of the 250 mail carriers in the United States.
    Mr. Leachim, who weighs two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, the parents’ names and what each child knows and needs to know. In addition(另外), he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification number. His computer brain puts the child’s voice and number together. He identifies the child without mistakes. Then he starts the lesson.
    Another advantage is that Mr. Leachim is flexible. If children need more time to do their lessons, they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off.

    Driving in a foreign country is always different in at least some ways from driving in your own country. Here are some general points regarding driving in New Zealand.
    l Visitors wishing to drive in New Zealand do not require an international driver’s license but are required to carry their local driver’s license whenever driving.
    l Vehicles drive on the left-hand side of the road as they do in Britain, Australia, and Japan. Most rental vehicles will have a sticker reminding you of this important fact.
    l When the traffic light is red, you must stop. There is no left turn rule as in North America.
    l New Zealand road rules follow international standards but please note that in New Zealand vehicles turning left must give way to traffic turning right.
    l In general, if you are turning left (where there are give-way signs or no signs), give way to vehicles that not turning. In all other situations, give way to vehicles crossing or coming from your right.
    l Seat belts must be worn at all times while driving in New Zealand. This stands for the driver and passengers. The driver is responsible for ensuring all passengers are wearing their seatbelts.
    l Do not drink alcohol before driving in New Zealand—drinking and driving laws are strictly enforced.
    l Speed limits are in kilometres per hour (kph), not miles per hour (mph).
    Speed conversion: 1 kph equals 0.621 mph; 1 mph equals 1.61 kph.
    l The speed limit on the open road is 100km/h. In towns and cities the speed limit is 50km/h. Be sure to obey all school crossing speed reductions as speed cameras operate regularly throughout New Zealand.
    For further information and up to date road conditions visit: http://www.transit.govt.nz
    小题1:What can be learned from the passage?
    A．A passenger’s not wearing the seat belt has little to do with the driver.
    B．There will be a reminder for drivers to remember to drive on the left side.
    C．Cars passing a school in towns should drive at a speed of less than 31 mph.
    D．A foreign driver is expected to have a driving license issued by New Zealand.
    小题2:Which of the following statements correctly explains road rules in New Zealand?
    A. In Figure 1, Car B must give way to Car A.
    B. In Figure 2, Car B must give way to Car A.
    C. In Figure 3, Car B must give way to Car A.
    D. In Figure 4, Car B must give way to Car A.

    An independent college claimed to have become the first school in England to make Chinese a compulsory (强制的) subject for its pupils.
    Richard Cairns, the headmaster of Brighton College, said the move aims to recognize the importance of China as the world’s fastest growing economy.
    Chinese will become one of the core subjects at the 1,200-pupil college from September. At present the school has only a “handful” of native Chinese students, but it hopes to attract more in the future.
    Mr Cairns, who made the announcement in his first week as head of the high-achieving college, said, “One of my key tasks is to make sure that the pupils at Brighton College are equipped for the realities of the 21st century, and one of those realities is that China has the fastest growing economy in the world.
    “China has replaced Britain as the world’s fourth-largest economy. We in Britain need to face up to this challenge, see it for the trading opportunity that it is, and ensure that our nation’s children are well-placed to thrive (茁壮成长) in this new global reality.
    “A better understanding of the language and culture of China will be hugely important to the advantage of the children of Brighton College.”
    Mr Cairns said he hoped the Chinese children already at the college would help and encourage their fellow pupils to learn their language.
    In order to lead the way, Mr Cairns, a historian from Oxford, plans to take part in the first Chinese class as a pupil. “I have agreed to join the first Chinese class as a pupil. I think it is the best way for me to show the pupils here how important I regard this new addition to our core subjects.”
    小题1:The passage mainly tells us ________.
    A．how to face up to new challenges in the 21st century
    B．the realities of the 21st century
    C．the fastest growing economy in the world
    D．about a school which will make all its pupils learn Chinese
    小题2:The college makes its students learn Chinese mainly because ________.
    A．Chinese is a language spoken by the largest population in the world
    B．it realizes the importance of China as the world’s fastest growing economy
    C．Chinese is the easiest language for the students
    D．there are many native Chinese students at the college
    小题3:What is Mr Cairns’ attitude towards the development of China?
    A．He sees it to be a threat.B．He thinks of it as a danger.
    C．He considers it to be an opportunity.D．He regards it as an encouragement.
    小题4:Which of the following statements is NOT true according to the passage?
    A．The Chinese students at the college have already helped their fellow students
    to learn Chinese.
    B．The school is the first in England to make Chinese a compulsory subject.
    C．Mr Cairns has just been made head of this high-achieving college.
    D．In Mr Cairns’ opinion, learning Chinese will be a great help to his students.
