一、 She used to be a history teacher.

【句型介绍】该句句意为"她过去是一名历史老师"。 used to do sth. 表过去经常做某事,暗示现在已不再如此,句中to后接动词原形。只能用于过去时态,并且可用于所有人称。其否定形式为used not to ... 疑问形式为Used you to ... ? Used he to ... ? 等。而在口语中或不太正式的书面语中,否定形式为didn't use to ...,疑问形式为Did you use to ... ? Did he use to ... ? 等。

He doesn't smoke these days, but he used to (somke). 他现在不抽烟,但是他以前抽。

【句式比较】 1. be used to do sth.,被动语态结构,意为"被用来做某事",句中to后接动词原形。

This machine can be used to produce juice. 这台机器可以用来做果汁。

2. be / get used to (doing) sth.,习惯于做某事,句中to为介词,后接名词、代词、动名词。

I'm not used to the noisy city life here. 我不习惯这儿喧嚣的城市生活。

Are you used to singing loudly in public places? 你习惯在公共场所高声唱歌吗?

【特别提醒】注意各句型中to后面的动词形式。

二、 what is worse

【句型介绍】 意思为"更糟糕的是",常作为插入语,强调后出现的情况比先出现的情况更糟糕,含有强烈的感情色彩,常可替换成worse than all /ever, to make the matter worse。

It was very dark outside, and what was worse, it began to rain. 外面很暗,而糟糕的是,天开始下雨了。

I started very late, and worse than all, I met with a traffic jam. 我出发得很迟,更糟糕的是,又遇到了交通阻塞。

【句式比较】 1. what's more,更何况,强调后出现的情况程度远远超过先出现的情况。

I'm not afraid of it, because I work hard, and what's more, many friends will help me. 这一点我并不害怕,因为我工作很努力,更何况许多朋友会帮我。

2. besides也有"更何况"之意,其用法与what's more相同。

I'm sure he will be fired, because he has been late so many times, and besides he has caused so much loss to our company. 我确信他肯定会被解雇,因为他迟到了这么多次,更何况他给我们公司造成了这么多损失。

【特别提醒】 通过语境区分各句型。

三、 We're having a family meeting.

【句型介绍】该句句意为"我们要开一个家庭会议", are having从结构上看是现在进行时态,但它表达的是将来时态。在口语中come, go, fly, leave, move, travel等表位置移动的动词常用现在进行时表示一般将来时态。

I'm leaving for Shanghai next Monday. 我下周一要去上海。

He's moving into a new house tomorrow. 他明天要搬进新房去。

【特别提醒】 注意这类动词在句子中的时态。
