连接副词when，where，how，why等。

在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则不用否定形式,而将主句谓语动词think等变为否定形式;？（否定转移）

e.g. I don’t think you are right．

在think，believe，imagine，suppose，guess，hope等动词以及I’m afraid 等后，可用so代替一个肯定的宾语从句，还可用not代替一个否定的宾语从句：

e.g. ---Do you believe it will clear up?

---I believe so. / I don't believe so. (或I believe not.)

Where there is a will, there is a way.
