期末專題2--非謂語動詞
在句子中充當除謂語以外的句子成分的動詞形式叫做非謂語動詞。非謂語動詞分為三種形式：不定式，動名詞和分詞（分詞包括現在分詞和過去分詞）。
1）不定式
時態\語態 主動 被動
一般式 to do to be done
完成式 to have done to have been done
2）動名詞
時態\語態 主動 被動
一般式 doing being done
完成式 having done having been done
3）分詞
時態\語態 主動 被動
一般式 doing being done
完成式 having done having been done
否定形式： not +不定式， not + 動名詞， not + 現在分詞
一、不定式
（一）不定式的常考形式
1. 一般形式：He decided to work harder in order to catch up with the others.
被動形式：He preferred to be assigned some heavier work to do.
語法功能：表示與謂語動詞同步發生
2. 完成形式：He pretended not to have seen me.
被動形式：The book is said to have been translated into many languages.
語法功能：表示發生在謂語動詞之前
（二）不定式�？嫉目键c
1. 不定式做定語----將要發生
2. 不定式做狀語----目的
3. 不定式充當名詞功能---To see is to believe.
（三）不定式的省略
1. 感官動詞 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel
+ do 表示動作的完整性，真實性
+ doing 表示動作的連續性，進行性
I saw him work in the garden yesterday.
昨天我看見他在花園里干活了。（強調“我看見了”這個事實）
I saw him working in the garden yesterday.
昨天我見他正在花園里干活。（強調“我見他正干活”這個動作）
感官動詞后面接形容詞而不是副詞：The cake tastes good; It feels comfortable.
（2） help help sb do help sb to do help do help to do
（四）有些動詞后只跟不定式如
want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect, allow sb to do, cause sb to do , permit sb to do, enable sb to do, love to do, warn sb to do, be able to do
begin to do, start to do
（五） 有的時候to后面要接-ing形式
look forward to; be used to; be alternative to; be similarity/similar to.
二. 動名詞： 具有動作性特征的名詞
1）是名詞 seeing is believing
2）具有動詞性特征可以帶賓語 reading books is necessary
（一）動名詞的形式
一般形式：I don't like you smoking.
完成形式：I regret not having taken your advice.
被動形式：This question is far from being settled.
（二）動名詞�？嫉狞c
1. 動名詞做主語，謂語動詞為單數
2. 在動名詞和不定式中，做為介詞的賓語是動名詞
3. 動名詞的否定直接在其前加否定詞,通過代詞的賓格或所有格形式給出邏輯主語。
I would appreciate_______ back this afternoon．
A. you to call B. you call C. you calling D. you're calling（Key：C your calling 也對）
I regret not having taken your advice.
4. 有些詞后只能接動名詞
admit; appreciate; avoid; celebrate; consider; contemplate; delay; discontinue; dislike; enjoy; escape; excuse; explain; feel like; finish; forgive; can't help; imagine; keep; it means; mention; mind; miss; pardon; practice; prevent; report; suggest; understand...
另外還有一些接-ing形式的常用說法：
it's no good; it's no/little/hardly any/ use; it's not/hardly/scarcely use; it's worthwhile; spend money/time; there's no; there's nothing worse than; what's the use/point...
5. 有些詞后加不定式和動名詞均可
remember, forget, try, stop, go on, mean后面用不定式和-ing形式，意義截然不容。
I remembered to post the letters. （指未來/過去未來的動作）
I remembered posting/having posting the letters. （我記得這個動作）
forgot與remember的用法類似。
I regret to inform you that… 我很遺憾地通知你…
I regretted having left the firm after twenty years. 為了"二十年前的離開"而遺憾... ...
try to 努力 You really must try to overcome your shyness.
try –ing 試驗 Try practicing five hours a day.
I mean to go, but my father would not allow me to. [打算、想]我想去，但我父親不讓我去。
To raise wage means increasing purchasing power. [意味著]贈加工資意味著增加購買力。
prefer的用法：
我寧愿在這里等。
I prefer to wait here. （所以啊，你不介意的話，我就等下去。）
I prefer waiting here.（我正在這里等，我就喜歡這么做。）
I prefer swimming to cycling. （這個句子里面就不能用不定式了。）
（三）need/want 后的-ing形式具有被動的意思。其中，want不太常用。
He needs （a lot of） encouraging.
（四）分詞：
現在分詞主動進行，過去分詞被動狀態
現在分詞的形式
1. 一般式： Do you see the man talking to the dean（主任）? （與謂語動詞同步發生）
2. 完成形式：Not having made preparations, they failed. （發生謂語動詞之前）
3. 完成被動形式：Having been adapted, the script seems perfect.（ 發生謂語動詞之前且表示被動）
（四）過去分詞
1. 過去分詞表示被動：Fight no battle unprepared.
2. 過去分詞的進行形式：You'll find the topic being discussed everywhere. （強調正在被做）
這三種非謂語動詞，都可以構成復合結構，非謂語動詞所修飾的成分是這些非謂語動詞的邏輯主語。它們之間的一致關系--主動還是被動，往往就是考點。
非謂語動詞具有靈活多變的特點，大家在判斷使用何種非謂語動詞形式時，可遵循以下規律：
1. 對比時間：對照謂語動詞的時間，確定非謂語動詞的時態形式。
非謂語動詞的各種時態形式都是依據句子的謂語動詞的時態形式而變化的。一般情況下，如果非謂語動詞所表示的動作在謂語動詞所表示的動作之后發生，我們就用不定式的一般式；如果表示動作與謂語動詞所表示的動作同時進行，我們就用現在分詞的一般式或不定式的進行式；如果表示動作在謂語動詞所表示的動作之前發生，我們就用現在分詞、不定式或動名詞的完成式（特殊情況下，也可用動名詞的一般式）。
2. 辨明邏輯：從非謂語動詞與其邏輯主語的關系判斷非謂語動詞的語態
如果非謂語動詞的邏輯主語是非謂語動詞動作的發出者，即兩者之間存在主謂關系，就用非謂語動詞的主動式；如果邏輯主語是非謂語動詞動作的承受者，即兩者之間存在動賓關系，就用非謂語動詞的被動式。
3. 兩方面結合，判斷時態、語態混合形式
有些非謂語動詞的形式把時態和語態的變化融合在一起，這時，我們可以把上述兩方面結合起來判斷。在非謂語動詞的邏輯主語是非謂語動詞動作的承受者的情況下，a）如果非謂語動詞所表示的動作與謂語動詞所表示的動作同時發生，就用現在分詞的被動式；b）如果動作在謂語動詞所表示的動作之后發生，就用不定式的被動式；c）如果動作發生在謂語動詞所表示的動作之前，就用現在分詞、動名詞或不定式的完成被動式。

【試題答案】
一、選擇題：1-5 ADDCD 6-10 ACCAC 11-15 CCDCA 16-20 CDBBA
二、強化闖關
1. 去掉having。 過去分詞作后置定語，在本句中表被動概念。
2. Guiding→ Guided。過去分詞作原因狀語，相當于原因狀語從句Because he was guided... （因為受……引導）。
3. being→be。to be working 是動詞不定式的進行式, expect sb. to be doing..., 意為“期待某人正在干……”。
4. lost→losing�，F在分詞的否定式作原因狀語，相當于原因狀語從句Because he never lost...，注意現在分詞的否定式是在分詞的前面加not或never。
5. 去掉Having，worn中的w改為大寫。worn out為過去分詞作原因狀語，表示在謂語動詞所表示的動作之前已經存在的狀態，相當于原因狀語從句Because she was worn out...,wear sb. out 意為使某人筋疲力盡。
6. surprising→surprised。過去分詞作原因狀語，相當于原因狀語從句because they were surprised...。
7. knowing→known。過去分詞作后置定語，known as意為“被稱為……，作為……被人知道”。
8. taking→taken。過去分詞構成的獨立主格結構作條件狀語。Everything taken into consideration相當于條件狀語從句If everything is taken into consideration（假如把一切考慮在內的話）。
9. be前加to。由時間狀語by the end of this month以及動詞complete和句子的主語work的關系判斷，應用不定式的被動式作后置定語，表示將來的被動動作。
10. take 前加to。不定式作后置定語，表示將來要發生的動作。注意take place無被動形式，也不能用其過去分詞作定語、狀語等。
