2014雅思语法讲义精选
一、名词性从句
概念：在一个英语句子当中，特定的成份必须用名词性结构来表示。名词性结构分为两种：名词和名词从句。名词从句就是语法功能相当于名词或名词短语的从句。简而言之,它是一种用从句来代替名词的句型。
考生常见问题: 缺乏“名词意识”.
1. (1). Save money is beneficial for one’s life after retirement. ( )
(2). There are more and more young criminals in the society has drawn the attention of media. ( )
2. Some people believe that mobile phones have taken the place of write letters. ( )
l 名词性从句重点句型
1. What从句
(写作) 通过打工，我们获得的不仅仅是工作经验。它同样能帮助我们把在学校里学到的东西运用到实践当中。
2. that 从句
(写作) 新东方能够培养出
3. 主语从句的变形
由连词that引导的主语从句，在实际使用中that从句一般由it做形式主语。
That practice makes perfect (熟能生巧) is known to us. (Rare)
It is known to us/widely accepted that practice makes perfect. (Common)
Tip: 在英语当中表示“据……”的句型一般都用It is + 过去分词 + that引导的主语从句(一般表示某种情况。)
据估计: It is estimated that …… 据报道: It is reported that …….
从图表当中我们可以看到: It could be noted from the graph that……
表示 “做……是重要/必要的”的时候, 主语从句必须用虚拟语气(should+动词原型).
It is important/essential/vital/necessary that sb/sth (should) do sth
在我看来,政府向老年人提供经济援助至关重要.
4. 由疑问词(how, when, where, whether, why, who)等引导的名词性从句
考生常见问题：
(写作) 很多人根本不明白存钱的目的何在.
Many people don’t know what is the purpose of save money. ( )
5. 宾语从句：
注意事项1：当主句的谓语是think, believe等时，如果后面跟的宾语从句要表示否定意思，则把谓语动词think, believe变成否定形式，宾语从句为肯定句形式。
例句： 我认为我们不应该允许大学生结婚。
I think we should not allow college students to get married. ( )
Tip2：It作形式宾语的情况。
有时可以用it来代替宾语从句作形式宾语，而将宾语从句放到句子后半部分。
(写作) 有些人认为我们花那么多钱在环保上面根本就是浪费时间。
Some people think that we spend so much money on environmental protection is simply waste of time. ( )
6. 表语从句：
什么是表语-跟在be动词后面的成份。如I am a student当中I是主语，am a student加在一起是谓语，而be动词am后面的a student就是表语。
考生常见问题:
(写作) The major reason why animals are facing the extinction is because people have paid little attention to the problem. ( )

二.定语从句
1.概念
用一个主谓结构完整的句子作定语(定语的两种形式adj+n/n+定语从句)，修饰前面的名词，代词，短语，甚至是整个句子的从句。简单来说就是把从句放在某个单词/词组/句子后面来对其进行修饰。
两个首先必须明确的概念： 先行词和关系词
Kung Fu Panda is the best cartoon movie (先行词) that/which (关系词) I have watched this year.
(阅读) There has been a significant increase in the number of women with dependent children who are in the paid workforce in Australia.
3.分类
定语从句可以分为限制性定语从句和非限制性定语从句两大类。
限制性定语从句： England was one of the first countries where scientists adopted and publicized Copernican ideas (哥白尼学说) with enthusiasm.
(阅读) One new keyboard included keys which produced letters which frequently occur together in English, like –ing and –th and –ed, so the word “thing” would take two strokes to write instead of five.
非限制性定语从句： Such expansion, which was to take the English language west to America and east to India, was supported by scientific developments such as the discovery of magnetism(磁力).
(阅读) It is very likely that the key board, which we have used for over a century, will soon be replaced by voice-activated computers which take dictation (听写) as we speak to them.
Tip: 在雅思阅读中，遇到__________________定语从句可以先忽略不看，先看句子的主干。
