10.Are you at least 17years old?Do you weigh more than 110ponds?Do you consider yourself fairly healthy?
If you answered yes to all of these questions,you should be donating (捐贈(zèng)) blood every two months.In my survey of my schoolmates,I found that only 50percent of them have ever donated blood and that only 1out of 13of them donate regularly.The lack (缺少) of blood donors is a serious problem that requires immediate action.
According to the American Red Cross Web pages,in the United States alone someone receives a blood transfusion (輸血) once every three seconds.People who benefit frm donations include cancer patients as well as babies.The need for blood never takes a vacation and neither should donors.
Let me tell you about Brooke,a three-year-old girl with cancer.Brooke has spent about half of her life in the hospital receiving treatments.Her treatment will require about 500units of blood in total,of which only 250units have been replaced.She still needs the other half of the total amount to continue her treatment.If she does't receive this blood,she will not live to start kindergarten.
Examples like Brooke's ae becoming all too common these days,with only 1in 20Americans donating blood and this number keeps dropping each year.These facts are extremely worrying considering that nearly half of us here will need blood sometime in our lives.
You can now see the seriousness of the problem with the lack of blood donations.Fortunately,it isa problem that can be easily solved.Each and every one of you can be part of the solution.All you have to do is go to the nearest Red Cross and donate your blood.

解答 CBBA
1 C 細(xì)節(jié)題. 根據(jù)文章第二 段In my survey of my schoolmates,I found that only 50percent of them have ever donated blood and that only 1out of 13of them donate regularly. 可知作者在第二段主要是通過陳述自己的研究發(fā)現(xiàn)來解釋說明獻(xiàn)血者少這一問題.故選C.
2 B 細(xì)節(jié)題. 根據(jù)文章第三 段in the United States alone someone receives a blood transfusion (輸血) once every three seconds. 不難看出市場(chǎng)對(duì)血液的強(qiáng)烈需求,故選B.
3 B 細(xì)節(jié)題. 根據(jù)文章第四 段Her treatment will require about 500units of blood in total,of which only 250units have been replaced.She still needs the other half of the total amount to continue her treatment. 可知Book還需要250單位的血液,故選B.
4 A 主旨大意題. 通讀全文可知本文的目的是勸說人們義務(wù)獻(xiàn)血.故選A.
