18、一般现在时表将来的2种情况:
拟定或安排好的事情、一定要发生的动作:The train arrives at 10.
在时间状语从句、条件状语从句、让步状语从句中一般现在时表将来
19、过去即将要发生的动作:was/were about todo sth.
20、句子中出现过去时,才会使用过去完成时表过去的过去-一直延续到过去的动作
I was tired. I had been working sincedawn.
21、常用句型:
It is adj. for sb.to do sth.
It is adj. of sb. to do sth.(形容词评价某人)
22、经常接疑问词+不定式的动词:learn, ask, discuss, explain, know, remember, forget, understand, think, consider, decide.
如I have to learn how to study English.
23、主谓一致
the number of+复数名词作主语时,谓语动词用单数
a number of+复数名词时,谓语动词用复数
someplentyofa lot of,谓语动词根据所修饰的词而定
a quantity of谓语动词用单数;large quantities of谓语动词用复数
24、谓语动词就近一致:
either…or…/neither…nor…/not only…but also…谓语动词和靠近的主语一致(常考)
25、同位语从句
常跟同位语从句的名词或短语(常考):belief /doubt /hope /report /word /opinion /idea…使用举例:We have some doubt whether they can complete the task on time.
26、直接引语和间接引语
变间接引语要向前推一个时态!例:
He said,”I am sorry.”
He said that he was sorry.
27、定语从句who/whom的用法(介词+whom)例:
He is the man who lives next door.
I have many friends to whom I am going to send postcards.
28、定语从句that/which的用法,通常可以互换,但下列情况必须用that(改错常考):
先行词是all,much,few,little,something等不定代词时
先行词有the only,thesame,the very修饰时
主句是以which开头的特殊疑问句时
先行词既有物又有人时
先行词是序数词、形容词最高级时
29、as和which用法辨析,引导非限定性定语从句
as的先行词只能是句子,which的先行词可以是词。
30、表示一…就的引导词
as soonas/immediately/instantly/the moment/no sooner than/hardly
31、no sooner与hardly在句首时,要求句子倒装。
32、so that连用引导目的/结果状语从句
so adj./adv./many/few+that:There is so little time that…
such adj.+名词+that:Kathy is such a lovely girl that…
33、强调句型:It is/was被强调的部分that/who句子剩余部分,和定语从句的区别:
It was 8 when I left home.(定语从句)
34、"wish +宾语从句",表示不大 可能实现的愿望
表示现在的不能实现的愿望:主语+过去时;
表示过去的不能实现的愿望:主语+had done;
表示将来的不能实现的愿望:主语+would/could do
35、It was +时间段+before…."过了多久才……"
It was not long before…."不久,就……"
It will (not) be +时间段+before…."要过多久(不久)……才……"(before从句谓语动词要用一般时态)
36、as if/though+主语+did/had done…好像……(表示现在或将来的情况用过去时;表示过去的情况用过去完成时)[参考句型4]
[例句]
Our head teacher treats us as if we were her own children, so all the students in our class think highly of her.
37、as, though, although引导的让步状语从句。
[注意]although位于句首;though位于句首或句中;as位于句中=though。它的词序是把句中强调的形容词、副词、动词或名词放在连词前。
38、in case of…(+n.) "以防;万一";
in case that…"以防,万一……"(谓语动词用一般现在时态或should+动词原形)
