1.Three teenagers ffered t d sme vluntary wrk during the schl wanted t paint a picture f the park near her hme.
Infinitive(不定式)
定义: 主要行为动词后面的动词都采用了”t+动词原形”的结构(有时可以不带t)。 (注:动词不定式没有人称和数的变化,在句子中不能做谓语。)
Presentatin
用法一: 不定式作宾语是及物动词后带t的不定式,表明意图、希望或决定的内容等。我们常见的动词+ t d sth. 的结构主要是动宾结构。 通常只能接不定式作宾语的动词有:agree (同意); ffer (提出); intend, plan (打算,计划); demand, ask (要求); prmise (答应); help (帮忙); prepare (准备); decide (决定); refuse (拒绝);dare (敢于); chse (选择); wish,hpe,want, expect (希望,想要); fail ;(不能;忘记); pretend (假装); manage (设法); determine (决心)。
为了便于记忆,我们可用以下口诀: 同意提出做计划, 要求答应来帮忙。 准备决定遭拒绝, 敢于选择有希望。 不能做到莫假装, 设法做成决心坚。eg. He agreed t help us. 他同意帮助我们。 My parents ffered t take us arund the teahuse. 我的父母主动提出带我们去参观茶馆。 We all hpe t see the great musician. 我们都希望见到那位伟大的音乐家。
特殊疑问词与不定式常连用作宾语,在功能上相当于一个宾语从句,但不能构成复合宾语。这些词为:knw, decide, ask, frget, get, remember, like, learn, think, tell, want, wish, advise, shw等。eg. I dn’t knw what t d. 我不知道该怎么办。 I haven’t decided hw t g there. 我还没决定怎样去那里。 The map can shw yu where t g. 这张地图可以告诉你往哪走。
Using verbs + t + infinitives:
Three teenagers ffered t d sme vluntary wrk during the schl hlidays.Cindy wanted t paint a picture f the park near her hme.
Sme verbs can have ther verbs after them. We usually use t befre the secnd verb. We call these secnd verbs infinitives.We can use verbs + t + infinitives in sentences.
An infinitive is the (base/ -ing/ -ed) frm f a verb.
Wrk ut the rule
chse hpe ffer wantdecide learn plan wish
We ften use t + infinitives after these verbs:
We can use questin wrds + t + infinitives after decide, knw, learn and remember.D yu knw hw t help disabled children?
Things t remember
1. I hpe _______(see) yu in my birthday party.2. D yu decide ________(cme) with me?3. She culdn't decide which restaurant _______(eat) at.4. D yu want ________(g) with me?5. Last summer I tk a curse n hw _______(make) dresses.6. He pretended _________(nt see) me when I passed by.
用所给词的适当形式填空:
Mark and his mther visited Vivien. Mark is telling his friends abut the visit. Cmplete his wrds with the crrect frms f the verbs in brackets.
We _______________(decide/ meet) Vivien tday. We _____________(want/ help) her in sme way. When we arrived, Vivien was very happy. She ____________(begin/ talk) t me abut her schl. She said, “I __________(like/ g) t schl, but I dn't have any friends. I feel lnely.”

wanted t help
began t talk
Mum gave her sme advice. Then Mum asked me t give Vivien her present, but I _____________(frget/ bring) it! Vivien said, “It's OK. I ___________(hpe/ see) yu again sn.”
frgt t bring
Using verbs + bjects + t + infinitives:
Annie taught Tim t sing beautiful sngs.We want them t be happy.
We can als use verbs + bjects + t + infinitives in sentences.
We can infinitives withut t after sme verbs, such as let and make.Mum made me g t bed early.
用法二: 许多动词可跟一个宾语 + t d…构成句子,句中的不定式作宾语补足语;否定形式为“动词+宾语+nt t d…”。eg. My bss tld me t type ut tw letters. 我的老板让我打两封信。 I didn't expect yu t arrive here s sn. 我没有料到你会来得这么快。 Please remind me nt t be late fr the meeting. 请提醒我开会不要迟到。
感官动词see, hear, ntice, bserve, watch, feel, listen t, lk at及使役动词make, have, let等后面常接不带t的动词不定式作宾语补足语,但这类动词用于被动结构(have不用于被动结构)时,则不定式要带t。eg. He saw her enter the rm. 我看见她进了房间。 I heard her lck the dr. 我听见她锁上了门。 A child was seen t enter the building. 有人看见一个孩子进入大楼。 She was ften heard t sing this sng. 经常听到她唱这首歌。
