2.句型分析

(1)If you are looking for entertainment, stay at home and watch TV. 如果你正想找乐趣,就呆在家里看电视。

这是if 引导条件状语从句。意为“如果,假使”。例如:If you are ill. you must see the doctor. 如果你病了,就必须去看医生。

在if引导的条件状语从句或when引导的时间状语从句中,如果主句是将来时态,从句的谓语动词用一般现在时代替将来时。例如:Lucy will see a film, if she has a time. 如果Lucy有时间,她就去看电影。

(2)Be sure to see this exhibition at the Lido Gallery. 一定要看这次在Lido Gallery的展出。

[用法]be sure to do sth.用在祈使句中,不是表示判断,而是表示对对方的要求,意为“务必要”,“一定要”。例如:Be sure not to forget it!千万别忘记呀!

由be sure构成的句型有:

①be sure+of/about+动名词或名词,意为“确信……”;“对……有把握”。例如: He is sure of success. 他自信会成功的。

但是如果后面要接反身代词时,则只能用be sure of,即be sure of oneself,意为“有自信心”。例如:Joan will have an examination next week, but she is not sure of herself. 琼下周要参加一个考试,但她对自己没有十分把握。

②be sure+不定式,意为“必定”、“必然会”、“准会”。例如:It is sure to rain. 天一定会下雨。

③be sure+宾语从句,意为“确信某事一定会……”。例如:I’m not sure whether I’ve met him before. 我不能确定以前是否见到过他。

(3) For your next vacation, why not consider visiting Singapore? 你为什么不考虑到新加坡度下一次假呢?

  consider意为“考虑、细想”。其常用于下列句型:

①consider + 从句。例如:Li Lei began to consider how he could pass the exam. 李雷开始考虑如何通过这次考试。

  ②consider + doing sth 例如:I am considering changing my job. 我正考虑换个工作。

  ③consider + sth(名词)。例如:You should consider the matter very well. 你要好好考虑这件事。

(4)Not only do I feel good about helping other people, but I get to spending time doing what I love to do. 关于帮助别人,我不但感觉很好,而且我开始花时间做我喜欢做的事。

   not only … but also意为“不但……而且”,其中also可以省略。它的用法如下:

  ①它可以连接句子的主语、谓语、表语、宾语等,强调but also引出的内容。当用来连接主语时,谓语应与最近的主语保持一致。例如: I went to see not only him but also his brother. 我不仅是去看他,而且去看他的弟弟。 (连接宾语)

Not only the students but also their teacher likes football. 不仅学生们喜欢足球,老师也喜欢。(连接主语,谓语likes与teacher的人称和数保持一致)

She can not only sing but also dance. 她不但会唱歌而且会跳舞。(连接谓语)

  ②当Not only位于句首时,前一个分句倒装,即谓语或部分谓语提到主语前面。但连接并列主语时除外。例如:Not only did he come, but also he was very happy. 他不但来了,而且很高兴。

(5)Although tea wasn’t brought to the western world until 1610, ……。尽管西方世界直到1610年才有茶叶,……。

 although意为“虽然……,(但是)……”,用作从属连词,引导让步状语从句。although(虽然)与but(但是)不能同时用。另外在英语句子中,because与so,little, few与no都不能同时出现在一个句子中。例如:①Although he is very old, he still works hard. =He is very old, but he still works hard. 他虽然年纪很大,但是他仍然努力工作。

②Because Kate got up very late, she missed the train. = Kate got up very late, so she missed the train. 因为Kate起床很玩,所以她没赶上火车。

我们可以把这种用法简记为:用because不用so,用but不用though;有了few或little,句中也不出现no。

(6)Walles was so convincing that hundreds of people believed the story. Walles(说的)很确信,因此有数百人都相信这个故事。

so+形容词或副词+that ...引导结果状语从句。意思是“如此……以致于……”。例如:When the football fans saw Beckham, they got so excited that they cried out. 当球迷们看到贝克汉姆的时候,他们如此激动以致于大喊大叫。

   “so … that”结构可以用 “too…to”结构或者 “…enough to…”结构来替换,从而把一个复合句变成简单句。方法有:

①如果that从句是肯定的,一般用enough to 改写。如:

 The ice here is so thick that we can skate on it.

   →The ice here is thick enough to skate on.  

②如果that从句是否定的,一般用too…to结构改写。如:

David was so careless that he didn’t find the mistakes in his test paper.

→David was too careless to find the mistakes in his test paper.

当主句和从句的主语不一致时,要在不定式前加上逻辑主语for sb.。例如:

The problem is so hard that I can’t work it out.

→The problem is too hard for me to work out.
