Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seeming unlimited number of antibodies, each specifically targeted at an invading microbe or foreign substance.
40、Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seeming unlimited number of antibodies, each specifically targeted at an invading microbe or foreign substance. (A) seeming unlimited number of antibodies, each specifically targeted at (B) seeming unlimited number of antibodies, each targeted specifically to
(C) seeming unlimited number of antibodies, all specifically targeted at (D) seemingly unlimited number of antibodies, all of them targeted specifically to
(E) seemingly unlimited number of antibodies, each targeted specifically at
这题看了两三个CDer的总结,说排除CD选项是因为“all和后面的an invading microbe or foreign substance单复数不一致”,我觉得这个总结是错误的。
这里的target是participal分词,表被动,还原为主谓宾即为each is targeted specifically at...关于target用法求解牛津高阶,verb1:把...作为攻击/批评目标,The missiles were mainly targeted at the US. verb2:面向...The campaign is clearly targeted at the young.这里target at sth/sb的at后跟的是目标对象,用被动态是因为物不能自己瞄准,是靠人或其他什么来使它瞄准,故需要习语搭配at引出目标。个人理解,也可以记住target at这个习语,固定搭配。
但是在曼哈顿里面有一个栗子是
the usa comprises 50 states, each of which is united by a federal government 是错的,应该用all.因为the implication is that each state has its own federal government.
求问这两个不矛盾么?
