二、重点句型

③ 辨析only if与if only
Only if 意为"只要，只有"，通常引导陈述语气的真实条件句，主句部分常为部分倒装语序
eg. Only if we link the disease to drinking water will we draw such a conclusion
If only 意为"但愿，要是······就好了"，常引导虚拟语气的条件句、感叹句
eg.If only I had another chance
2. It seemed that... 似乎······ （可改为简单句：sb./sth. seemed to do...）

3. neither...nor 连接两个并列主语。
① 当neither...nor连接两个名词或代词作主语时，谓语动词的数遵循"就近"原则，即谓
语动词的数要与nor后面的名词或代词保持一致。

4. have/get sth. Done
是"have/get 宾语 宾语补足语"的结构，意为"让某事被做，遭遇某事"，做事的主体是"别人"而非主语"自己"，此时sth.与动词do为被动关系，故用过去分词。
eg. I will have my new house decorated next month
5. Yet Copernicus' theory is now the basis on which all our ideas of the universe are built
句中on which all our ideas of the universe are built是"介词 关系代词"引导的定语从句， 修饰the basis
注：介词的确定要遵循"一先、二动、三意义"的原则。"一先"即根据先行词的某种习惯
搭配来确定介词；"二动"即根据定语从句中动词所需的某种习惯搭配来确定介词；"三
意义"即根据从句的意义来确定介词。
eg. The teacher for whom you are waiting is coming
