动词不定式作定语或状语
不定式在句中可作主语、宾语、表语、定语、状语和宾补。高考侧重考查不定式作定语和状语的用法。
1. 不定式作定语
(1)不定式作定语通常要放在被修饰词的后面,往往表示将要发生的动作。
The weather will be sunny in the days to come.
未来几天将是晴天。
(2)中心词是序数词、形容词最高级、the last/the only/the next 或被这些词修饰时,用不定式作定语。
Zhang Jian is the first Chinese to swim across the Bohai Sea.
张健是第一个游过渤海的中国人。
He was the only one to finish the task on time.
他是唯一一个按时完成任务的人。
(3)抽象名词 time, way, reason, chance, courage, opportunity, ability 等后以及不定代词 something,
nothing, little 等后常用不定式作定语。
A subway is an effective way to solve traffic problems in a big city.
地铁是解决大城市交通问题的有效方法。
(4)“there be+主语+to do”和 have(有) sth. to do 结构中,不定式作后置定语。
There is nothing to worry about.
没什么可担心的。
He has a lot of work to do today.
今天他有大量的活要干。
2. 不定式作状语
(1)作目的状语。可位于句首或句末,其前可加 in order/so as,但 so as to 不可位于句首。
I got up early (in order) to catch the 6:30 train.
我早起是为了赶那趟六点半的火车。
(2)作原因状语。
I am glad to see you.
见到你很高兴。
He smiled to think of a clever plan.
想到了一个聪明的计划,他笑了。
(3)作结果状语,表示出人意料或不太好的结果,常与 only 连用;而现在分词作结果状语则表示自然而然的结果。
I hurried to the post office, only to find it closed.
我急忙赶到邮局,结果发现邮局关门了。
