并列连词either…or…用法(在线收听) |
either…or…主要用于表示选择,其意为“要么……要么……”“或者……或者……”,用于连接两个性质相同的词或短语。如: You can have either this one or that one. 你拿这个或那个都可以。
You must either go at once or wait till tomorrow. 你要么马上走,要么等到明天。
We can finish the work either this week or next week. 不是这星期就是下星期我们就可完成这项工作。
在具体使用not only…but also…时还应注意以下几点:
1. either…or…连接两个成分作主语时,谓语动词通常与其靠近的主语保持一致。如:
Either you or I am to go. 你或我必须有人去。
Either he or you are right. 要么他对,要么你对。
但在非正式文体中,有时也会一律用复数谓语。如:
If either David or Janet come, they will want a drink. 大卫或珍妮特来的话,是会要喝酒的。
2. either…or…除可连接两个词或短语外,有时也可连接两个句子。如:
Either you must improve your work or I shall dismiss you. 要么你改进工作,要么我就辞退你。
Either you'll leave this house or I'll call the police. 你要是不离开这座房子,我就叫警察来。
3. either…or…的否定式可以是not either…or…,也可以是neither…nor...。如:
He didn't either write or phone.=He neither wrote nor phoned. 他既没写信又没打电话。
注意,正如不能说either…not 一样(但可说not…either),英语习惯上也不说either…or…not,如不能说:Either he or his wife hasn't come. 可改为:Neither he nor his wife has come. |
