复合句中容易犯错的句子

1 容易犯错的句子

1-1 我知道她住在哪里。

I know where does she live. ×

I know where she lives. √

宾语从句无论是表示陈述，还是表示疑问，都必须用陈述语序，即主语在前，动词在后。

1-2 他说他那时正在踢足球。

He said that he is playing soccer at that time. ×

**He said that he was playing soccer at that time. **√

当主句动词是一般现在时、现在完成时或一般将来时，宾语从句的动词可根据需要使用相应的任何一种时态。

I know /she is a teacher./she will come back in two days./she has just finished it./she went to Taiwan two days ago.

当主句动词是一般过去时，宾语从句的动词必须使用过去时态的相应形式。

He asked me /what I wanted./where I was going./when I would leave./why I had come here.

1-3 老师说地球是圆的。

The teacher said that the earth was round. ×

**The teacher said that the earth is round. **√

当宾语从句表示的是客观真理或客观规律、自然现象、格言，其动词不受主句动词的时态限制，习惯上使用一般现在时。

The teacher said the sun rises in the east and sets in the west.

老师说太阳从东方升起，西方落下。

The teacher **told usthe earth is **one of the sun’s planets.

老师告诉我们地球是太阳的一颗行星。

1-4 我认为你的答案不对。

I think your answer isn't right. ×

**I don't think your answer is right. **√

当宾语从句表示否定之意，且主句中主语是I，动词为think ， believe等时，习惯上是将否定移转，使主句成为否定式，而从句使用肯定式。

1-5 我认为你不是老师，是吗？

I don't think you are a teacher, do I? ×

I don't think you are a teacher, aren't you? ×

I don't think you are a teacher, are you? √

若附加疑问句中含有宾语从句，且主句是I think ，I believe等表示看法的用语，附加疑问部分的主、动词一般要与从句的主、动词一致。

1-6 他们正在谈论格林先生是否会讲中文 。

They are talking about if Mr. Green can speak Chinese. ×

They are talking about whether Mr. Green can speak Chinese. √

连词if或whether引导宾语从句时，一般可互换使用，但当作介词宾语时，只能用whether。

1-7 他一回来，我就会告诉他这个好消息。

I will tell him the good news as soon as he will come back. ×

I will tell him the good news as soon as he comes back. √

在由when， before，after，as soon as等引导的时间状语从句中，如果主句的动词是一般将来时，从句中的动词用一般现在时代替将来时。

1-8 - 他为什么没来上学？ - 因为他病了。

－Why didn't he come to school? －For he was ill. ×

－Why didn't he come to school? －Because he was ill. √

虽然for也可表示原因或理由，但回答why的问句只能用because来回答，表示直接的原因。

1-9 如果你不赶快的话，你上课要迟到了。

You’ll be late for class if you won’t hurry up. ×

**You’ll be late for class if you don’t hurry up. **√

在以if引导的条件状语从句中，如果主句的动词是一般将来时，从句往往用一般现在时代替将来时。

1-10 昨天当我的朋友来的时候，我正忙于做作业。

While my friend came yesterday, I was busy doing my homework. ×

When my friend came yesterday, I was busy doing my homework. √

while只可指一段时间，不可指时间点，所以在while从句中动词必须是延续性动词；而when主要指时间点，也可用来表示一段时间，所以when从句中的动词可以是延续性的；也可以是非延续性的。

1-11 他把功课写完，才去睡觉。

He went to bed until he finished his homework. ×

**He didn't go to bed until he finished his homework. **√

在含有until/till从句的复合句中，如果主句中的动词是非延续性动词，则用否定句式，表示这一动作直到何时才发生。

1-12 他太生气了，以至于说不出话来。

He was too angry that he couldn’t speak. ×

**He was so angry that he couldn’t speak. **√

He was too angry to speak. √

在"so+形容词或副词+that"句型中，so不能用very，too或其他程度副词替换。该句也可用“too,,,to”句型来表达。

1-13 我不知道他是否会来。

I don’t know if he comes. ×

**I don't know if he will come. **√

这里的if作“是否”解，相当于whether,引导宾语从句。由于主句是一般现在时，宾语从句表示的动作尚未发生，所以要用一般将来时。

1-14 这个房间比那个房间大得多。

This room is more bigger than that one. ×

This room is very bigger than that one. ×

**This room is much bigger than that one. **√

形容词或副词比较级前不能用very,更不能用more来修饰，可用much，even，a little等来修饰。
