地大《大学英语(3)》FAQ(六)

?1. 动名词

1.1 动名词由动词本相加词尾-ing构成。动名词是名词性的,它同时存在动词特点跟名词特点,在逻辑上表达的是一个举措或状况,在语法上表现的是名词特点。动名词的名词特点表现在可能用作主语、宾语等。

(1)Preparing for the Olympic Games is a huge undertaking. (preparing 作句子的主语)

(2)Without preparing a strong bid, a city will not win the competition to host the games.(preparing 作介词without的宾语)

2. 表达指令跟警告

2.1 用祈使句表达指令跟警告

祈使句多用于表达指令。在祈使句中利用不带to的动词不定式,表示频度的副词(如always, never等)一类的词,一般放在动词之前。

(1)Always take the stairs.

(2)Never go by car when you could walk.

最好利用Please could you …, If I were you , I’d…, Could you…, please如许的构造,让语气听起来比较缓跟。

(1)Open the door, please, could you?

(2)Please, could you open the door?

(3)Could you open the door, please?

2.2 用should表达指令跟警告

should 用于提出警告、倡议或是比较断定的看法。should表示“应当怎样”。

(1)You should look for exercise opportunities all the time.

(2)If you feel dizzy, you should stop.

(3)You should go to the less popular classes.

(4)You should do stretches before you start.

Should 的主语可能是人也可能是事物、变乱。

(1)If she trains hard, she’ll win the competition.

(2)If a country wins a lot of medals, the people will feel proud.

3.2 if 领导的从句在主句前时,需用逗号与主句隔开,如在主句之后,一般不必逗号。

(2)It will encourage huge economic growth if we win the bid.
