I do , too.(我也是）） I don’t either.(我也不）
I hope so.我希望如此。 I hope not.(我希望不会）
I think so.(我认为是这样） I don’t think so.(我不认为是这样）
同意或不同意的表达方式：
think的特殊用法——否定的转移
当主语是第一人称（I, we）,think表示“看
法”，其后接宾语从名时，若宾语从名要表示否定意义，在形式上应该否定前面的主名。
(主句中谓语动词用否定形式，从句谓语动词用肯定式）
I don't think you are good at music.
我不认为你很擅长音乐
I don't think it is going to rain.
我不认为天要下雨。
注意：谓语动词是hope时，宾语从句中的否定词不能转移。
I hope you weren't ill.
我希望你没有生病
作谓语动词时，否定前移现象.类似的词有：
suppose（假设，认为）
believe（相信，认为）
expect（期望，认为）
imagine（想象，猜想）
I don't suppose my friend can finish this work．
我猜想我的朋友不能完成这项工作。
Let's practice
I don't believe I get lost.
我不相信我迷路了。
Let's practice
She doesn't expect to go abroad.
她并不期待着出国。
Let's practice
注意：下列情况不出现否定转移：
1.当有情态助动词与think连用。
如：I can't think what you mean.
I don't imagine the story.
我没有想象这个故事。
Let's practice
2.当think 前有副词修饰时。
如：I really think the job isn't fit for you at all .
3.在think 后所接的宾语从句中，
如有no,nothing,never等否定词时。
如：I think Jenny is never late for school .
I think people will fly in cars.
In the future, fly in cars!
I think people will live on Mars.
In the future, live on Mars!
I think people will travel to the moon.
In the future, travel to the moon!
And we will have a better life!
A better life!
Yes, we will!
