问题 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.

选项 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

答案 E

解析 根据未划线部分的an invading microbe及每个选项中都有的specially,可断定targeted分词短语修饰单数形式each,而不是复数形式all,由此可排除C、D;在A、B中,名词短语seeming unlimited number表明seeming和unlimited共同修饰number,即为“看上去的、不受限制的数量”。而E中,seemingly unlimited number则表明seemingly修饰形容词unlimited,unlimited修饰名词number,意为“看上去不受限制的数量”,显然,A、B中该名词短语的意思不符合逻辑,而E的表达清楚。另外,target是与at搭配,而不与to连用。
