二、让步状语从句
让步状语从句主要有六种结构,前三种比较简单,也没有考过,我们只做简单的介绍。后三种结构比较重要。
1.though, although引导的让步状语从句:
though和although的意思差不多,都是“尽管……”、“虽然……”的意思。区别在于though比较常用,而although多用于比较正式的场合,常放在句首,语气比though稍微重些。
如:
Though he is very old, yet he is quite strong.他虽然年纪很大了,但还很强壮。
Although it is raining, they’re still working in the field.虽然在下雨,但他们仍在地里干活。
2.even if (though) + 让步从句,+主句:
even if (though)即使
如We will make a trip even though the weather is bad.即使天气不好,我们也要去远足。
3.whether ……or …… + 让步从句,+主句:
whether……or……不管……都……
如Whether you believe it or not, it is true.信不信由你,这是真的。
4.no matter+疑问词(how/ what/ when /where /whether)+ 让步从句,+主句
no matter……不论……,不管……
    如No matter how big the storm is , we can meet it . 风暴再大我们也能顶得住。
5.疑问词+-ever+让步从句,+主句:
疑问词+-ever+让步从句,+从句 =  no matter+疑问词+让步从句,+主句。
如Whatever the terms used, the facts are plain enough.不管怎么说,事实再清楚不过了。
相当于:No matter what the terms used, the facts are plain enough.
6.被强调的形容词或副词 + as +让步状语从句,+主句:
这种句式意思是“尽管……”。和though, although引导的让步状语从句的意思一样,可以相互转换。
如Old as he is, he is quite strong.
相当于:Though he is very old, yet he is quite strong.

三、主语从句
英语中主语从句有三种类型(重点在第一,第三):
1.由连接代词(who/whoever/whom/what/whatever/which)或连接副词(when/where/why/how)引导的主语从句:
如:
Whatever he saw and heard on his trip gave him a very deep impression.旅途中的所见所闻给了他很深的印象。
When and where the new hospital will be built remains a mystery.这座新医院将在什么时间,什么地方建设还是一个未知数。
2.由连词that引导的主语从句:
如That you need more practice is quite obvious.毫无疑问你需要更多的练习。
相当于:It is quite obvious that you need more practice.
3.由whether--or引导的主语从句:
如Whether we will go or not remains undecided.我们是否去还没有决定。

四、宾语从句
1.由连接代词或连接副词引导的宾语从句:
如:
This is what I am eager to do. 这就是我想要做的。
Could you tell me where he lives?你能告诉我他住在哪里吗?
2.由连词if或whether引导的宾语从句:
Let me know whether (if) you can come (or not) tomorrow.让我知道你明天能否来。
3.同位语从句由that引导,前面的词多为news, fact, idea, plan, suggestion等抽象名词,这些词也叫先行词。
如The fact that he does so in so short period of time challenges explanation.
这么短时间内他就完成这件事这似乎有点不可思议。
