8、t our village looks like C. how does our village look like D. how our village looks like 分析:考查名词性从句的语序.在名词性从句中,除了关联词要提到句首之外,一律要用陈述句语序。当关联词含疑问意义时,有的学生就会受习惯影响错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。本题句子的意思是:这些照片会告诉你我们村子是什么样。本题中根据引导词what要作介词like的宾语,而副词how不能作介词like的宾语,所以首先排除C、D,而A项是疑问句语序,故只能选B。 1.

A. if B.

11、 how C. whether D. why分析:本题句子的意思是:医生真正怀疑的是我母亲是否能很快从重病中恢复过来.whether引导的是表语从句. 在下列情况下，whether 不能被 if 所取代：1. 引导主语从句用whether， 如： Whether it is true remains a problem.2. 引导表语从句用whether， 如： The question is whether you should accept it.3.引导同位语从句用whether， 如：They had no idea whether they should go to the part
