which指物在从句中作主语,宾语或表语(作宾语时可以省略)
who指人在从句中作主语,宾语或表语
whom指人在从句中作宾语
whose指人或物在从句中作定语
as指人或物在从句中作主语,宾语或表语
but指人或物在从句中作主语,宾语或表语
注意:指物时,whose+名词=the+名词+of which或of which+the+名词
2、as的用法
(1)常用于下列结构:such…as; so…as;the same…as; as…as
注意:the same…as表示同一类,不同一个
the same…that表示同一个
(2)as与which的区别
a、位置不同
as可放在主句后,主句前或主句中间;which只能放在主句后。
b、as起连接作用,表达说话人的观点、看法,并指出主句内容的根据或出处,意为“正如,正像”。
Which相当于并列句,可以用and this来代替,意为“这一点,这件事”。
注意:as常用于下列结构:as we know/ as is known to all, as we all can see, as has been said before/above,
as might be excepted, as is often the case,一般不能用which代替as。
c、在从句中作主语时,which既可作系动词be的主语也可作实义动词的主语,而as只可作系动词be的主语。

不定式做主语:
1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的,经常的动作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (对等)
注:
1).不定式作主语时,谓语用单数
2).当主语较长,谓语较短时,常用it做形式主语,而将不定式放到谓语的后面。
it做形式主语,不定式放在谓语动词之后常用于下列结构中:
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名词+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
注意: probable和possible均可作表语,但possible可以用不定式作真实主语,而probable不能用不定式作真实主语。
It is probable for him to come to the meeting.(错)
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.

He looked just as he had looked ten years before. 他看起来还与十年前一样。
The question is whether they will be able to help us. 问题是他们是否能帮我们。

All this was over twenty years ago, but it's as if it was only yesterday.
这都是20多年前的事了,但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。如:
It looked as if it was going to rain. 看起来天要下雨了。
