请判断下列句子是简单句、并列句还是复合句：

2.You help him and he helps you. 并列句
3.My suggestion is that we should study step
by step.
用it作形式主语的主语从句
如果主语从句太长，为了避免句子结构头重脚轻，可以用it作 形式主语，而把主语从句放在主句谓语部分之后。
It is a pity that you didn't go to see the film yesterday.
It is reported that China has sent another man-made satellite into orbit.
spend too much time online.
B 3.The first request that he made was to ask for freedom.
4. Do you have any idea where we will be sent?
B 5. Is this the company where your father works? B 6. This is the reason that he gave for his absence.
It 作形式宾语
it 不仅可以作形式主语，还可以作形式宾语，而把作真正 宾语的that从句放在句尾，特别是用在带复合宾语的句子 中。 I think it quite clear that he preferred coffee to tea.
I think it best that you should seek for a solution to the problem.
（that指代promise，又在从句中充当主语。）
I. Tell the function of the clauses in the following sentences说出下列从句的功能：A: Appositive（同位 语）; B: Attributive（定语）
1. His proposal that we go there on foot is acceptable. 2. Many teachers hold the view that teenagers should not
的内容：我们队取得了决赛胜利。）
The news that you told us is really encouraging.
（从句对“消息”加以限定：是你告诉我们的，而非 来自其他渠道。但消息是何内容却不得而知。）
二、同位语从句与定语从句的不同之处
2、引导词 区别：同位语从句中，that：无成分，用于 肯定句； 定语从句的that是关系代词，既指代先行词又须在从句 中充当成分。
