假设你是某国际学校的学生会主席李华。针对你市血库告急的状况,你校将组织年满18周岁的学生进行无偿献血活动。请你根据以下提示,用英语写一封倡议书。

1. 鼓励无偿献血的原因(供不应求,献血后短时间内即可恢复) ;

2. 无偿献血需要注意的方面(保证身体健康,献血后适当补充营养) ;

3. 鼓励大家积极参加。

注意:1. 词数100左右(开头和结尾己给出,但不计入总词数) ;

2. 可适当增加细节,以使行文连贯。

Dear fellow students, 

                                                                                                                                                                                                                                                                      

                                                    Students' Union

One possible version:

Dear fellow students, 

            Lots of blood is needed every day in the hospitals of our city to cure people of certain diseases,and many are deadly ones.

However,onthewholethereisn’tenough blood available at present,so all the students above 18 should do something to help out. Besides,it has been proved by medical research that blood can be reproduced in a short time after the donation.

            When you decide to help,first you i should check to make sure you are healthy t without any forbidden diseases. After the I donation,you should eat something that!provides you with good nutrition.

            Join in and help those in need!

                                                  Students’ Union

             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.
