考向预测
☆ ☆ ☆ ☆ ☆一 不定式作状语
不定式可以在句中作目的状语、结果状语、原因状语、条件状语等。
1. 不定式作目的状语表示目的，可译为“去、来、为了”等，其逻辑主语也是全句的主语。
2. 不定式作结果状语，多用于too…to, enough to do, only to do, so…as to, such as to等结构。
3. 不定式用于be+ adj+to do构成结果状语，不定式主动形式表示被动意义。易错点一：不定式作目的状语的错用
秘籍：分析句子结构和句意。不定式作目的状语时，其前可加in order或so as，可以置于句首。但so as
to不可置于句首。
易错提醒：to do不定式作目的状语位于句中时，不能用逗号。
（2024年浙江卷1月）However, if you’re shopping for one, buying extra ____ 5 6____
(benefit) from price reductions doesn’t make sense.
变式 1：_______(accept) as an Olympic event, a sport must be played in at least 75 countries on at least 4
continents.
变式 2：（2022 新高考 I 卷）The plan will extend protection to a significant number of areas that were
previously unprotected, bringing many of the existing protected areas for giant pandas under one authority
___________ (increase)effectiveness and reduce inconsistencies in management.
易错点二：不定式作结果状语错用
秘籍：不定式作结果状语时，表示“出乎意料、想不到”的结果，而分词作状语，表示“自然而然、可想
而知”的结果。
He hurried to the station, only ____________(tell) that the train had left.
变式1：He worked deep into the night, ________(prepare) a paper.
变式2：Would you be so kind as_____________ (carry) the luggage for me?
二 不定式作定语不定式作定语必须后置。同时注意以下几点：
1. 作定语的不定式与所修饰的名词之间往往有动宾关系，如果这个不定式是不及物动词，后面需加介
词。
2. 某些名词后只能跟不定式作定语，不接 of doing，常见名词有ability, attempt, desire, effort, failure,
promise tendency等。
易错点：不定式作定语
Fearful that he might have an intention (harm) her, Helen started to run.
变式1：As is known to us, Yang Liwei is the first Chinese astronaut (send) into space.
变式2：What is the best way for you (solve) this problem?
变式3：The airport (complete) next year will help promote tourism in this area.
三 不定式作补语
1. see，notice, let, make, hear, listen to, see, observe, watch, have, feel。(不定式作宾补省to，但在被动语态中
to应加上)
2. ask, allow, cause, help, invite, tell, persuade, expect, teach,order, persuade,want, warn等动词(只接to do
后作宾补) 。
3. 用于“with+名词+不定式”，表示一个主动的、将要发生的动作。省略with后构成的“名词/代词+不定
式” 构成独立主格结构。
4. be said类动词：be said/believed/reported/known to do类句型，可以转化为It is said that…。不定式根据语
境还可能用进行式、被动式或完成式。易错点：不定式作宾语补足语

them 41 (lift) out of the steamer basket without allowing them tearing or spilling any of their contents.
变式1：Modem methods of tracking polar bear populations have been employed only since the mid-1980s, and
are expensive __________ (perform) consistently over a large area.
变式2：Facebook is considering to make its website page (look) more beautiful.
四 不定式作主语
1.不定式作主语表具体行为，表特指(对比：动名词作主语表泛指，是抽象行为) 。
2.不定式作主语三情况：直接作主语；It作形式主语；wh-to do短语作主语(谓语用单数)。
3.常考句型It is+ adj. +of / for sb to do sth 结构；It takes sb. time to do sth.等。

变式1： On our way to the house, it was raining so hard that we couldn't help wondering how long it would take
__________ (get)there.
变式2：When and where to start the programs ____________(remain) unknown.五 不定式作宾语
1.只接to do作宾语的动词:妙记--mecarfipsd霉咖啡不是的
manage, expect, choose, afford/ agree/ attempt, refuse, fail, intend, plan/pretend/promise, seem,
decide/desire/determine
2.接to do/doing意义不同的动词：forget, remember/regret, go on, stop, can’t help, mean, try。
forget to do 忘记要去做某事（未做） remember to do 记得将要做某事（未做）
forget doing 忘记已经做过某事（已做） remember doing 记得已经做过某事（已做）

六 不定式作表语不定式作表语，表示主语的内容，如职业、职责或性质等，起解释说明作用，也可表示目的或愿望等。主
语有实义动词do,作表语的不定式可省to。
The purpose of this activity is (encourage) the students to speak English.
变式1：Anyhow my goal is _________(provide) humans with a life of high quality.
七 不定式的特殊用法
1. 不定式的省略感官动词和使役动词接不定式作宾补时省略to（注意被动语态中to应加上）；
2. 某些不定式与be连用，如to blame, to seek, to let等。
3. 省去to的不定式

do nothing but do sth 别无选择只好做某事 can’t help but do sth. 禁不住做某事
Why not do sth? 何不做某事？ prefer to do…rather than do sth宁愿做……而不愿做……
would rather do…than do…宁愿做……而不愿做……
4. 在一定的上下文中，为了避免重复，有时不定式可以省略，但通常保留不定式符号 to。注意，不定式
