2、es她认识的那些女孩是护士。(3) . he will marry as pretty a girl as he can find. 他要尽可能找漂亮的女孩结婚。(4) . here is no difficuit a problem as none of us can solve这个问题太难，我们无法解决。as引导的非限定性的定语从句与which的区别。1. 用来引导非限定性定语从句时，可以指代整个主句的内容，as和which可以换用he turned out to be very successful, which (as)was more than we could expected.他

3、竟然成功了，这一点我们没有预料到。he saw the play, as (which) he had hoped.他看了这出戏剧，这是他所盼望的事。2. as用来应当非限定性定语从句，只指代整个主句的 内容，从句可置于句首，句中，或句尾.as is known to all , edison invented the telephone 二edison inventd the telephone, as is known to all.=edison , as is known to all , invented the telephone众所周知，爱迪生发明了电话。3非限定性定语从句中的谓

4、语为被动式时，常用as作 主语。如：be said /known/announced/reported/discussed 等等。grammar, as has been said before , is not a set of dead rules.正如前面所说的，语法不是一套死规则。as is known to all, taiwan is a part of china. 众所周知，台湾是中国的一部分。4. as引导的非限定性定语从句，有“如、似、正如”的 含义。因此，下面的句式中多用as。as has been said above 女口上所说as anybody can see正如

5、人人都看到的那样as we had expected正如我们所预料的那样as seems likely 似乎可能as i remember (it) 女卩同往常一样as (it) appears正如看出的(1) things are not always as they appear事情并 不总像从外表看到的那样。(2) the work is making as much progress as can be expected .这项工作的进展很理想.5. which引导非限定性定语从 句，指代整个主句内容时，从句只能置于尾。the decision was postponed, which

6、 was exactly what he wanted 决议延期作出，这正是他所要求的。6. which引导的非限定性定语从句，指代主句中的一个 词(即先行词)，从句置于先行词之后，可在句中或句尾。the football match , which i watched yesterday , is very interesting .我昨天看的那场足球赛非常有趣。7. which引导的非限定性定语从句，指代整个主句的内 容，从句的谓语带有宾语，有待还带有宾语补足语。(1) after that things improved, which astonishedme后来事情有了进展，这使我很吃

7、惊。(2) water changes into steam, which is known to be a physical change水变成蒸气，这被认为是一种物理变化。8. which引导的非限定性定语从句，指代整个主句的 内容，从句的意思与主句相反，即从句维否定式或带有否定 前缀的形容词。(1) she was very patient towards the children , which her husband seldom was 她对孩子们很耐心，她丈夫却很少这样。(2)he can write a letter in english , which i cannot.他能

8、用英文写信，而我不能。(3) he has married again , which was unexpected. 他又结婚了，这是没有预料到的。practice：1. the british are not familiar with different cultures and other ways of doing things , is often the case a. as b. that c, so d. it2. sometimes the earthquake is so violent that it can destroy the whole city happene
