每天一句英语口语-不得不让步

每天一句英语口语:不得不让步

I saw that she was right, so I had to back down. 我知道她是对的，所以我不得不让步。 学习亮点: 首先是 back down

放弃;让步;打退堂鼓

He backed down after I saw his mistake. 在我拆穿他的大话后,他让步了。

I see he has backed down from the position he took last week. 我注意到他放弃了上星期的立场。

其次,今天恒星小编就还要跟大家来讲解下have to的用法.

have to 是一个比较特殊的情态习语，虽然也具有情态动词的功能，但却与其他的情态动词不同。它有人称、数和时态的变化，其否定式和疑问式的构成方式也与情态动词不一样。同学们在使用have to 时必须弄清它的真面目，否则容易出错。 一、have to 与其他情态动词一样也是后接动词原形，表示外界的强制作用，强调被迫性。含有不情愿的色彩，常译为“必须，不得不”。

二、have to 可用于多种时态，而且不同时态使用不同的形式：一般现在时中，主语为第三人称单数时用has to ; 一般过去时中，用 had to。 have to 还可以用在其他的情态动词之后。例如： I have to do some washing. 我必须洗洗衣服。

She has to look after her little sister. 她不得不照顾她的小妹妹。

I had to do my homework last night. 昨晚我不得不做作业。

I think he may have to help his Dad in the garden. 我想他可能不得不在花园里帮他爸爸。 三、have to 的否定式和疑问式一般要借用助动词do的适当形式构成。have to 的否定式是don’t have to; has to 的否定式是doesn’t have to; had to 的否定式是didn’t have to。have to的疑问式同样也借用助动词do的相应形式构成。例如：

He doesn’t have to do the homework now. 他没有必要现在做作业。

—Do I have to go there now? 我现在就得去那儿吗？

—Yes, you do. （No, you don’t have to.） 是的，你必须去。（不，你不必。）

We didn’t have to answer the question yesterday. 昨天我们没有必要回答这个问题。

注：情态习语是助动词、不定式或副词的组合。
