152. When the technique known as gene-splicing was invented in the early 1970's, it was feared that scientists might inadvertently create an "Andromeda strain," a microbe never before seen on Earth that might escape from the laboratory and it would kill vast numbers of humans who would have no natural defenses against it. (A) it would kill vast numbers of humans who would have no natural defenses against it (B) it might kill vast numbers of humans with no natural defenses against it (C) kill vast numbers of humans who would have no natural defenses against it(虚拟语气没有错) (D) kill vast numbers of humans who have no natural defenses against them (E) kill vast numbers of humans with no natural defenses against them 1平行一级排除 A,B might escape ,,,,, and kill,,,, Choices A and B each violate parallel construction by introducing a new independent clause, it would kill... and it might kill... 2单复数 二级排除D,E a microbe ,, 对应单数 it 3虚拟语气 In addition, choices B, D, and E lack would and thus do not express the conditional 4修饰限定/非限定 who定语从句 非限定 with介词短语 限定性 (如果这里用with就意味着特指那些没有natural defenses against it 的人,也就是说有一些人是有natural defenses against it
由本题可见,OG还是要认真的看,这儿重复了多个前面讲过的错误,而在这儿就一笔带过,没有再仔细解释(比如限定和非限定修饰的区别)
