Grammar
What part does the underlined part
serve as in each sentence?
A tree has fallen across the road.
You are a student.
To find your way can be a problem.
Smoking is bad for you.
“How do you do?” is a greeting.
What she said is not yet known.
That we shall be late is certain.
It is certain that we shall be late.
We can see from these sentences that
a sentence serves as subject, so we call
it Subject Clause.
主语从句
• 主语从句是在复合句中充当主语的从句，通常放在主句
谓语动词之前或由形式主语it代替，而本身放在句子末
尾。
• How the book will sell depends on its author.
That he is the best student in the class is obvious.
引导主语从句的关联词有三类：
(1) 从属连词that。 如：That they were true sisters
was clear from the facial resemblance between
them.
很明显，她们确是亲姐妹，她们的脸型很相似。
(2) 从属连词whether。如：
Whether he’ll come here isn’t clear.
他是否会来这里还不清楚。
(3) 连接代词who, whom, whose, what, which,
whoever, whatever, whichever
连接副词 where, when, how, why。如：
What she did is not yet known. 她干了什么尚不清楚。
How this happened is not clear to anyone.
这事怎样发生的，谁也不清楚。
Whoever comes is welcome. 不论谁来都欢迎。

Notice :
What we need most

Agreement in subject clauses
在主语从句中，谓语一般用单数。
无论他说什么都不重要
。
Whatever he says is of no importance
无论谁说这话都不对。
Whoever says that is wrong．
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.
