从英语的句子结构上说，除了修饰名 词的定语和修饰动词的状语外，在千 变万化的句子中可归纳为五个基本句
式，一般地说，某些动词用在某一句
式中，下面把这些句型和常用的动词 进行归类。
简单句基本句型实例
1. She came．/ My head aches.
主语 ＋ 谓语
2. She likes English.
突破方法
做题三步曲：
步骤一：首先分清主句和从句。 步骤二：分析从句缺何种成分。 步骤三：根据分析，选择恰当的连接 词
Note: 连接词： that 与 what 的区别
What he said makes me happy.
That a new teacher will come is true . 请你归纳
为了避免主语冗长,句子头重脚轻,经常用it作 形式主语,主语从句放在后面作真正的主语. 例:
That we shall be late is certain. -- It’s certain that we shall be late.
Eg: 很肯定他会赢得比赛的。 ____is It certain that he will win the match.
和陈述句的语序相同。

四.主语从句
一.主语从句的位置.
1.句首，谓语动词之前。 What we need is your help. Whoever break the rule will be punished. 2.句末，前有it 做形式主语。 It is obvious that I am happy.
考点一：it 作形式主语
同位语从句与定语从句的区别
Do you know the fact that he stole the car ? （解释说明） Do you know the fact that they were talking about? （修饰限定） 试区分： • The news that our team won the game is true. • The news that you have heard isn’t true. • 1.同位语 • 2.定语从句
但谓语动词用单数还是复数，不可一概而论，而要 视句子的意义而定 What I need is money. What I need are books.
