which的用法有哪些？

1、定语从句用which情况：

1，非限定性定语从句

2.关系代词前有介词

3.关系代词后有插入语

如：

1、The

sun

heats

the

earth

,

which

makes

it

possible

for

plants

to

grow

.

2、The

bodies

on

which

the

forces

act

are

in

equilibrium．

3、Here

is

the

English

grammar

book

which,as

I

have

told

you

will

help

improve

your

English.

2：如果第二个问题问的这两个短语还是与定语从句有关的话，那

so后面都加形容词，that后面加句子，as后面加名词。如：The

biscuits

are

so

delicious

that

I

want

to

eat

more.

订攻斥纪俪慌筹苇船俩The

food

is

not

so

good

as

those

we

ate

in

Bill's

home.

so...as用于否定句，和as...as意思一样。后者肯定句否定句都能用。

希望能帮到您！
