我选A和A作者: netbanker 时间: 2009-11-28 03:25
1. A 不对， fat they think is。。。 they 是谁？B 2. D， A of which... there are 不对， which 指的是magnetic fields , 应该用exist作者: leadwest 时间: 2009-11-28 09:51
1. 选 B. B. wild animals have less total fat than （这里助动词do省略） livestock fed on grain and more of a kind of fat thought to be （less... and more...并列，共同作为have的宾语）（they thought代词they单独出现无指代，改为过去分词）
2. 选 A. of which 当中的which修饰system，无错误。整个句子是一个大的平行对称结构，Researchers have announced that.... and that.... 也就是announce了两件事情。这里是两个并列的that引导的宾语从句，因此and后面的that不可省略。作者: ulyssesangel 时间: 2009-11-28 15:19
2.以前说there be结构不对，是因为there be结构表示的是自然存在的东西，这里的磁场肯定是自然存在的东西，there be结构用在这里就合理了
