问题
In the early part of the 20th century, physicians discovered that blood transfusions often failed because ______.
If a patient whose blood type is O needs blood transfusion, who can be the donor?
选项
A、Blood typea.
B、Blood typeb.
C、Blood type AB.
D、Blood type O.
答案
D
解析
文章讲到O型血的人是universal donors,但不是universal recipients。因为在第二段最后一句“Persons With blood type AB have no antibodies and can receive any of the four types of blood; thus blood types O and AB are called universal donors and universal recipents, respectively.”中respectively是“各自地,独立地”的意思。同时另一句“In type O blood, neither substance is present on the red cells, but the individual is capable of forming antibodies directed against red cells containing substance A or B.”其句意是:O型血的人红细胞中没有该物质,但个体的人能形成抗A或B型红细胞的抗体。所以,只有O型血的人能给O型人输血。
