1.only引导的倒装句型:only +状语 (或状语从句)坐落句首时,语句部分倒装。
例句: Only by diligence and honesty can one succeed inlife. 只要勤勉、正派,一个人在生活中才干成功。
留意:但 only润饰主语时,不倒装。例句: Onlythat girl knew how to work out the problem. 只要那位女生知道怎样解那道题。
2.wish引导的虚拟语气:wish 后边的从句,当表明与现实相反的状况,或表明将来不太可能完成的期望时,其宾语从句的动词方式为:
(1)表明对现在状况的虚拟:从句动词用过去式或过去进行式表明,be 的过去式用were.
I wish I knew the answer to the question. 我期望知道这个问题的答案。(惋惜不知道。)
(2)表明对过去状况的虚拟:从句动词用had +过去分词。( 实际上现已糟蹋掉了。)
(3)表明对将来的片面期望:谓语动词方式为“would/ should/ could/ might +动词原形”。在这种情况下,主句的主语与从句的主语不能相同,由于主句的主语所期望的从句动作能否完成,取决于从句主语的情绪或志愿(非动作名词在外) 。
I wish it would stop raining. 期望雨能中止。
留意:若wish 后的宾语从句顶用 would,能够表明恳求,一般意味着说话人的不快或不满。
例句:I wish you would be quiet. 我期望你安静一些。
3.as…as…引导的比较级:
(1)“as +形容词或副词原级+as+被比较目标”结构。例句:He studies as hard as you.他像你相同学习尽力。

例句:He has made it clear that he will not give in. 他标明他不会屈从。
5.The+比较级,the+比较级表明“越……越……”。
例句:The more scared we are, the stronger the difficultywill become.咱们越惧怕困难,困难就会变得越强壮。
6. 宾语从句:一般疑问句做宾语,引进if或whether
例句: I want to know if he will join us in thediscussion?
7. 否定词前置倒装:scarcely…when…
例句: Scarcely had he arrived at home when it began torain.
