3、謂語(yǔ)動(dòng)詞及非謂語(yǔ)動(dòng)詞的方法She got off the bus, leaving her handbag on her seat.She got off the bus, but left her handbag on her seat.由此可見(jiàn)，連詞在決定句子結(jié)構(gòu)以及謂語(yǔ)動(dòng)詞和非謂語(yǔ)動(dòng)詞的使用中起著關(guān)鍵的作用。非謂語(yǔ)動(dòng)詞使用條件個(gè)句子當(dāng)中，已經(jīng)存在一個(gè)主句（謂語(yǔ)動(dòng)詞）,又沒(méi)有連詞的情況下, 還有別的動(dòng)詞出現(xiàn)時(shí)。Some basic knowledge of the Infinitive.動(dòng)詞不定時(shí)的形式肯定式：to do sth 否認(rèn)式：not to do sth. 被動(dòng)式：to be d

4、one 完成式：to have done 動(dòng)詞不定式的句法作用法動(dòng)詞不定式有副詞，形容詞和名詞的特征，因此在句中可作主語(yǔ)、賓語(yǔ)、賓語(yǔ)補(bǔ)足語(yǔ)、表語(yǔ)定語(yǔ)、狀語(yǔ)等成份。Step 2 the Usage of the Infinitive.不定式時(shí)態(tài)的用法不定式的動(dòng)作與謂語(yǔ)動(dòng)詞同時(shí)發(fā)生時(shí)，或之后發(fā)生 用一般時(shí)態(tài) 1) He wanted _ (see) you. 2) I hope _(see) you again. 2. 強(qiáng)調(diào)不定式的動(dòng)作正在進(jìn)行時(shí)，用進(jìn)行時(shí)態(tài)When I came in, he pretended_ （read) a book. 3. 強(qiáng)調(diào)不定式的動(dòng)作在謂語(yǔ)動(dòng)詞之前發(fā)生時(shí)，用不定式

6、 Step 3 不定時(shí)的句法功能不定式做主語(yǔ)時(shí)，可以直接放在謂語(yǔ)動(dòng)詞之前Not to get there in time is your fault.注：常用it做形式主語(yǔ)，將to do放在位于之后，使句子保持平衡。句型1：It + 謂語(yǔ) + to do句型2：Its + n. + to do句型3：It is adj. for/of sb. to do sth作表語(yǔ)時(shí) 主語(yǔ) + be + to do sth 主語(yǔ)多為 duty / wish / hope / idea / plan / ambition/ dream / work / job 等 名詞 My ambition is to b
