             Scientists have long known that turtles,like many animals,find their way and direction at sea by sensing the invisible(无形的) lines of Earth's magnetic field(磁场) similar to how sailors use latitude(纬度)and longitude. But they didnt know

how turtles were able to return to the very spot where they were born.

              Now a study has the answer: Turtles also rely on Earths magnetic field to find their way home. That's because each part of the coastline has its own magnetic signature,which the animals remember and later use as an internal compass. It's not an easy way,though — the magnetic field turns slowly,and turtles have to change their nesting sites in response's pretty amazing how these creatures can find their way through this vast expanse of nothing/' said study co-author J. Roger Brothers.

              Turtles have a great range that surrounds all but the coldest waters of the world's oceans. Though they travel hundreds of miles out to sea,turtles seem to prefer coastal areas.

              Every year,thousands of volunteers walk along Florida's sandy beaches to count turtle's nesting sites,which provides scientists with a rich population data set. At the same time,researchers have been studying slight changes in Earths magnetic field along Florida's coasts to measure how the fields strength and other characters change over time. Brothers and his colleagues combined the citizen-science data on turtle nests and official data about the magnetic field to find how everything changed over time.

              Nathan Putman,a biologist with the National Oceanic and Atmospheric Administration's Southeast Fisheries Science Center,added,“Its really creative work,the type that makes you think, ‘Why didn’11 think of that?’ ”

              The results could also influence conservation ways for these endangered animals,said Brothers. The population of the animals has fallen due to pollution,and development in their nesting areas. Many conservationists surround turtles' nests with wire cages. Since these cages are usually metallic,the practice could affect the turtles,ability to find their way home.

32. Why does the author say “It's not an easy way”?

   A. Turtles always travel far away from home.

   B. Earth's magnetic field changes constantly.

   C. It's hard for turtles to feel the invisible lines.

   D. It takes turtles too much time to plan their route.

33. What is the main idea of Paragraph 4 ?

   A. How the data was collected.

   B. How important the research was.

   C. How the research was carried out.

   D. How meaningful the data is in modem life.

34. What does Nathan Putman think of the findings of Brothers and his team?

   A. There is still a long way to go.

   B. Their efforts are worthwhile and inspiring.

   C. They are the most important findings on turtles.

   D. The results may cause doubts from other scientists.

35. According to the last paragraph,why are some cages put around turtles’ nests?

   A. To expand their nesting areas.

   B. To help them rest comfortably.

   C. To guide them to their home.

   D. To prevent them from leaving.

              Some people believe that women are better drivers than men.1 ,others think that women make worse drivers. The idea that women make 2 driyers is a stereotype(刻板印象) . It comes from a time when women drove less than men,and 3 was seen as a man's responsibility,mere are certainly 4 views on this controversial questioji , 5 there a number of reasons why a woman, s prsonality makes her a more ccwipe纪咐(能胜任 的) driver.

              Firstly,women are more patient and polite towards other road 6 ,such as pedestrians and cyclists. In stressful situations they are more likely to stay 7 , and less likely to be involved in road rage (愤怒) ” incidents. Secondly,female drivers are more 8 so they take fewer risks,for example when overtaking. Thirdly,they are more responsible and 9  they tend not to drive when tired or after drinking alcohol.

              l0,many people argue that women cause accidents because they may react slowly because they 11  confidence. In addition,they are 12 disturbed,for example,by children in the car. Research also 13 that women find map reading more 14 than men,and can have problems with the difference between left and right. Despite the fact that women have more accidents,15 is often cheaper for them because the accidentslend to be minor. In particular,women have accidents when parking. This is because women often have 16 spatial(空间的;) ayareness. In contrast,men to 17  more serious accidents.

               To sum up,it can be seen that women make 18 drivers than men because of their 19 . This is generally 20 by the fact that women have fewer accidents and pay lower insurance than men. On balance,it is clear that women are less competitive and aggressive than men behind the wheel and therefore better drivers.
