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 in 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 ravel 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 farmers decide when to spray their crops.

A. the little creatures can fly very fast
B. they have no regular migrating courses
C. the wind"s direction is hard to foresee
D. their flight is long and high above ground
4. We can learn form the text that _______________.

In a test that challenged participants to remember numbers, a young chimp performed better than
Japanese college students.
Here"s how the test worked. At Kyoto University in Japan, human students and chimpanzee
participants sat in front of a computer. Five numbers, ranging from 1 to 9, were combined with one
another and then, they appeared at random places on the screen.
The numbers stayed on the screen for less than a second. In the first test, for example, participants
saw the numbers for 650 milliseconds(about two-thirds of a second).
Then, each number disappeared and they saw a white square instead. Participants had to touch the
squares in numerical order, based on the numbers that had been there a moment before. In this test, the
students touched the boxes in the correct order about 80 percent of the time. A young chimp named
Ayumu performed equally well.
During a harder test, participants were only able to see the numbers for 210 milliseconds.
This time, students only succeeded in putting the boxes in the correct order about 40 percent of the
time. But Ayumu still could select the boxes in the fight order nearly 80 percent of the time.
Some people have what"s called a "photographic memory," which allows them to remember a
surprising number of details after just a quick glimpse of something. Ayumu"s memory might work in a
similar way says lead researcher Tetsuro Matsuzawa.
The chimp"s young age might have something to do with his impressive performance, too. In previous
tests, the Japanese researchers found that young chimps performed better than their mothers.
The scientists are interested to see whether Ayumu loses his strong memory as he grows older. They
already know that young children sometimes have sharp memories when offered something photographical, but they lose this ability over time.

| Japanese Students Suffer from Pressure Last April,15-year-old Rei Iwasaki stopped her piano and flute lessons and began to study every day of the week. Her parents paid to send her to a "cram school(灌输式教学模式的学校)."She wanted very much to pass her exams. In February she did pass an all-day, five-subject examination and entered the high school she hoped to enter. Thirteen-year-old Akio Yoshiwara wasn"t so lucky. Unable to take the pressure of the exams, he hanged himself in February. He left a suicide note which said, "I did my best in this dear life, but it"s no good." Suicides are now a common part of life among students in Japan. The cause is the incredible pressure of the "examination hell." Even a number of teachers are committing suicide each year. When some students broke windows in a school near Tokyo, the principal blamed himself and wrote the following note: "The incidents were due to the lack of appropriate measures by the principal and I apologize. I am very tired. The Japanese educational system is much different from the American system. It is perhaps the most regimented(严密组织的) school system in any of the industrialized nations. Boys and girls wear uniforms and go to school six days a week --- 240 days a year compared to 180 in the U.S. Ninety- five percent graduate from high school compared to seventy-five percent in the U.S. Students don"t ask questions in class but only listen respectfully to the teachers. And every few years students are tested to see which school they will enter next. There is stiff competition for the "best" schools. The result is a well-informed, disciplined student, ideal for factory and company work and excellent at learning specialized skills. But there is little fun in education, little creativity and the incredible pressure of "examination hell." 1. It"s because ______ that many Japanese students committed suicide. A. they didn"t do their best in their lives. B. they were sent to a "cram school". C. of the most regimented school. D. they were unable to take the pressure of the exams. 2. Why did the principal kill himself? Because__________ A. He thought it was his fault that some students broke the windows. B. He was very tired. C. He couldn"t stand the pressure of the "examination hell". D. He blamed himself and wrote a note. 3. Which of the following ideas agrees with the title of the passage. A. The Japanese students love to study under pressure. B. The Japanese students do well under pressure. C. The exams give the Japanese students much pressure. D. The exams make the Japanese students commit suicide each year. 4. Which of the following is Wrong? A. The American educational system is much different from the Japanese system. B. To enter a high school, a student must pass an all-day, five-subject examination. C. The Japanese graduates from high school are much less than the American graduates. D. In Japanese education, there is little creativity as well as little fun. | ||||||||||||||||||||||||||||||
| Educating girls quite possibly gets a higher rate of reward than any other investment (投资) available in the developing world. Women"s education may be an unusual field for economists (经济学家), but increasing women"s contribution to development is actually as much an economic as a social issue. And economics, with its focus on encouragement, provides all explanation for why so many girls fail to receive an education. Parents in low-income countries don"t invest willingly in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else"s family and bear children. Girls are thus seen as less valuable than boys and usually have to stay at home to do housework while their brothers are sent to school. An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on developing all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. Few will argue that educating women has great social benefits. But it has huge economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 percent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant influence on health practices, including family planning.
