3、謂語動詞及非謂語動詞的方法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，連詞在決定句子結(jié)構(gòu)以及謂語動詞和非謂語動詞的使用中起著關(guān)鍵的作用。非謂語動詞使用條件個句子當(dāng)中，已經(jīng)存在一個主句（謂語動詞）,又沒有連詞的情況下, 還有別的動詞出現(xiàn)時。Some basic knowledge of the Infinitive.動詞不定時的形式肯定式：to do sth 否認式：not to do sth. 被動式：to be d

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

5、完成時 He is said _ (write) a novel last year. 4. 強調(diào)動作從過去某時開始，一直延續(xù)到現(xiàn)在，并可能持續(xù)下去時，用完成進行式 She is said _ (work) on the problem for many years. 不定式被動語態(tài)的用法 當(dāng)不定式的邏輯主語是不定式的承受者時，用被動語態(tài)It is an honor for me to be asked to speak here .She asked _ (send) to work in Tibet .The book is said _ (translate) into English.

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