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(fā)生在謂語動詞之前
二）不定式�？嫉目键c：

3）不定式充當名詞功能---To see is to believe.
三)不定式的省略

+ do 表示動作的完整性，真實性；

" 感官動詞后面接形容詞而不是副詞：The cake tastes good; It feels comfortable.

三、need/want 后的-ing形式具有被動的意思。其中，want不太常用。

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 starving troops 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) 動名詞常考的點
1)動名詞做主語謂語動詞為單數(shù)
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．（MET 1992）
A．you to call B．you call C．you calling D．you're calling（Key：C your calling 也對）

5有些詞后加不定式和動名詞均可
remember, forget, try, stop, go on, cease, 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。

3 分詞：
現(xiàn)在分詞主動進行,過去分詞被動狀態(tài)
現(xiàn)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(fā)生)
2)完成形式：Not having made adequate preparations, they failed. (發(fā)生謂語動詞之前)
3)完成被動形式：Having been adapted, the seems perfect.( 發(fā)生謂語動詞之前且表示被動)
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(diào)正在被做)
這三種非謂語動詞，都可以構(gòu)成復合結(jié)構(gòu)，非謂語動詞所修飾的成分是這些非謂語動詞的邏輯主語。他們之間的一致關(guān)系--主動還是被動，往往就是考點。獨立主格結(jié)構(gòu)中，要注意的是分詞與他前面的邏輯主語之間的主動被動的關(guān)系。
二：虛擬語氣和情態(tài)動詞
情態(tài)動詞的基本用法及其區(qū)別
最近幾年高考試題中常常借助語境來考查情態(tài)動詞的基本用法及其區(qū)別，因此在平時學習時準確理解和掌握情態(tài)動詞的基本用法十分重要。情態(tài)動詞的用法復雜多變，在高考試題中，命題者常常利用語境和句子之間意義上的細微差別來考查學生對情態(tài)動詞的理解和掌握。對于情態(tài)動詞，除了要求考生能夠準確掌握它們的基本用法外，還要充分利用高考試題所設(shè)置的語境來分析句子之間所體現(xiàn)的特殊關(guān)系。下面就近幾年來高考試題中出現(xiàn)的情態(tài)動詞的考點進行歸納分析，以便同學們復習掌握。
一、用"情態(tài)動詞＋have ＋done"結(jié)構(gòu)表示對過去動作的推測，高考試題中常用過去時態(tài)或過去的時間狀語給以暗示。情態(tài)動詞的這一用法可以用 "對立統(tǒng)一"來概括。
1．當試題的前句和后句在動作和意義上相互補充說明，且整個句意在動作和時間上是一個整體時，我們可用"統(tǒng)一"關(guān)系來解決這樣的試題。常見的結(jié)構(gòu)有：
must have done：
