二、让步状语从句
让步状语从句重要有六种构造，前三种比较简朴，也没有考过，我们只做简朴的介绍。后三种构造比较重要。
1．though, although指导的让步状语从句：
though和although的意思差不多，都是“虽然……”、“固然……”的意思。区别在于though比较常用，而although多用于比较正式的场所，常放在句首，语气比though轻微重些。
如：
Though he is very old, yet he is quite strong.他固然年龄很年夜了，但还很结实。
Although it is raining, they’re still working in the field.固然鄙人雨，但他们仍在地里干活。
２．even if (though) +让步从句，+主句：
even if (though)即便
如We will make a trip even though the weather is bad.即便气候欠好，我们也要往郊游。
３．whether……or…… +让步从句，+主句：
whether……or……不论……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……,不论……
如No matter how big the storm is , we can meet it .风暴再年夜我们也能顶得祝
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.不论如何说，毕竟再清晰不外了。
相称于：No matter what the terms used, the facts are plain enough.
６．被夸张的描述词或副词 + as +让步状语从句，+主句：
这种句式意思是“虽然……”。和though, although指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.
相称于：Though he is very old, yet he is quite strong.
三、主语从句
英语中主语从句有三品种型（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）指导的主语从句：
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.这座新病院将在什么时候，什么中央培植照旧一个未知数。
2．由连词that指导的主语从句：
如That you need more practice is quite obvious.毫无疑问你需要更多的练习。
相称于：It is quite obvious that you need more practice.
3．由whether--or指导的主语从句：
如Whether we will go or not remains undecided.我们能否往还没有决议。
四、宾语从句
１．由连接代词或连接副词指导的宾语从句：
如：
This is what I am eager to do.这便是我想要做的。
Could you tell me where he lives？你能通知我他住在那边吗？
2．由连词if或whether指导的宾语从句：
Let me know whether (if) you can come (or not) tomorrow.让我晓得你本日可否来。
3．同位语从句由that指导，背面的词多为news, fact, idea, plan, suggestion等笼统名词，这些词也叫先行词。
如The fact that he does so in so short period of time challenges explanation.
这么短时候内他就完成这件事这好像有点不可思议。
