【语法探索--动词不定式作状语和定语】
【要义详析】
一、动词不定式在句中作状语, 主要用来修饰动词和形容词, 也可用来修饰副词。
在句中, 不定式可作目的状语、原因状语、结果状语、条件状语等, 可表示目的、原因及结果等。
1. 目的状语, 置于句首或句末, 置于句首时常表示强调。为加强语气, 常与in order或so as 组成短语。
*A group of young people got together to discuss this question.
一群年轻人聚在一起讨论这个问题。
*In order to help him, we would do everything we can.
为了帮助他, 我们将尽我们所能。
【名师点津】
不定式作目的状语
(1)置于句首时只用to do / in order to do。如用于表示否定, in order 或 so as不能省略, 用 in order not to do 或 so as not to do形式。
*I walked quietly so as not to disturb the baby.
我安静地走路, 以免打扰婴儿。
(2)不定式作目的状语时, 其动作通常迟于谓语动词的动作。
*I said that to encourage him.
我这么说是为了鼓励他。
(3)不定式作目的状语可转换为 so that / in order that 或 so. . . that . . . 引导的目的状语从句。
*He worked very hard to pass the exam.
→He worked so hard that he could pass the exam.
→He worked hard so that/in order that he could pass the exam.
他非常努力以便能通过考试。
2. 结果状语, 多见于“too. . . to”; “enough to. . . ”; only to do(表示意料之外的结果的发生); so/such. . . as to(意为“如此……以至于……”)结构句中。
* I’m too tired to do well. 我太累了做不好。
*He is old enough to go to school . 他到上学的年龄了。
*He rushed back, only to find the book missing.
他冲了回来, 却发现书不见了。
* She is so proud as to look down upon others.
她太骄傲了, 看不起别人。
3. 原因状语, 多见于“sb. +be+adj. +to do. . . ”结构句中。
*I was very sad to hear the news.
听到这个消息我很难过。
4. 独立动词不定式多用作插入语, 表示说话人的心理状态或对事情的看法。
*I’d like to stay healthy, but to be honest, I only eat food that tastes good.
我想保持健康, 但说实话, 我只吃味道好的食物。
【名师点津】
现在分词与不定式作结果状语的区别
(1)动词不定式作结果状语强调的是一种意想不到的结果。
*Anxiously, she took the dress out of the package and tried it on, only to find it didn’t fit.
(2)现在分词作结果状语强调的是一种顺承的, 必然造成的结果。
*His father passed away, leaving him a little money.
二、动词不定式用作定语
1. 名词前有first, last, next, only等词以及最高级修饰时, 其后要用动词不定式。
*She was the first woman to win the gold medal in the Olympic Games.
她是第一个在奥运会中赢得金牌的女性。
2. 动词不定式作定语常放在名词或不定代词后面作后置定语, 表示尚未发生的动作。
*Let us give him something to eat.
让我们给他一些吃的东西。
*We have much homework to do tonight.
今晚我们有很多作业要做。
3. 当名词与定语之间存在动宾关系时。
*I usually have a lot of meetings to attend.
我通常有很多会议要参加。
*She is a nice person to work with.
她是一个很好的合作伙伴。
4. 抽象名词attempt, ability, chance, desire, determination, decision, plan, way或不定代词something, nothing等后面常用不定式作后置定语。
*But Janis Adkins has the ability and desire to do useful work.
但是詹尼斯·阿德金斯有能力和愿望去做有用的工作。
5. 当名词与定语有同位关系时。
*We got the order to leave the city.
我们接到了离开这个城市的命令。
6. 当名词与定语之间存在主谓关系时。
*We must find a person to do the job.
我们必须找到一个人来做这项工作。
*We need someone to go and get a doctor.
我们需要有人去请医生。
【知识延伸】
动词不定式作主语, 表语和宾语
1. 不定式作主语, 表示具体的某次动作。若不定式结构比较复杂, 常用it 作形式主语, 真正的主语放在句子的后面。

做早操对我们的健康有益。
*It’s important for us to learn English well.
学好英语对我们来说很重要。
2. 不定式作表语, 表示将来的情况, 说明主语的内容。其主语常常是wish, idea, task, purpose, duty, job等表示意向、打算、计划的词。
*His dream is to be a doctor.
他的梦想是成为一名医生。
*My work is to clean the room every day.
我的工作是每天打扫房间。
3. 不定式作宾语, 常跟在某些动词后。不定式作宾语的动词的记忆口诀:
决心学会选计划, 拒绝答应想假装;
主动设法愿希望, 同意请求帮一帮;
准备威胁易声称, 渴望申请败踌躇。
其对应的动词分别为:
decide/determine, learn, choose, plan,
refuse, promise, want/attempt, pretend,
offer, manage, expect/wish/hope,
agree, ask/beg, help,
prepare, threaten, tend, claim,
desire/long, apply, fail, hesitate。
4. 若不定式结构比较复杂, 通常用 it 作形式宾语, 真正的宾语放在句子的后面, 该用法常见的动词有think, find, make, believe, consider, suppose, feel等。
*He can’t afford to buy the expensive car.
他买不起那辆昂贵的汽车。
*I think it useful to learn a foreign language.
我认为学习一门外语是有用的。
