1.选择疑问句

 

含有or的问句称为选择疑问句。or之前的部分读升调,之后的部分读降调。这种疑问句不能简单地用Yes或No 来回答。选择疑问句把选择的余地缩小在数目有限的事物、行动等上面,可以有无限性的选择、3项选择以及两项选择。选择疑问句通常可以采用缩略形式,如:

 

Beef or lamb?  牛肉还是羔羊肉?

 

选择疑问句的例句如:

What would you like to drink?  你喜欢喝什么?(无限性选择)

 

Which/What would you prefer, tea or coffee?   茶和咖啡,你喜欢哪一种?(两项选择)

 

Would you like tea, coffee, or milk?   你喜欢茶、咖啡、还是牛奶?(3项选择)

 

How shall we go, by bus or by train?   我们怎么走?乘公共汽车还是坐火车?

 

Did you go there, or didn't you?   你去了那儿还是没有去?

 

Did you or didn't you go there?   你是去了还是没有去那儿?

 

2.一般现在时的单数第3人称形式(可参见 Lessons 47~48语法部分。)

 

词汇学习  Word study

I like lamb, too.  我也喜欢小羊肉。

Can I come, too?  我也来,行吗?

I, too, have been to Shanghai.  我也到过上海。

 

2.either  adv.

也,而且(一般用于否定句,位于句末,前面通常有逗号):

He doesn't like the house, and I don't like it, either.  他不喜欢这所房子,我也不喜欢。

If you do not go, I shall not go, either.  如果你不去,那么我也不去。
