【正文】 ______ . He always works hard.A learn B to learn C learned D learning四、 動(dòng)詞不定式的否定式。如：He wants to move to France and marry the girl. Help 可帶 to ,也可不帶to, help sb. (to) do sth. Why…/Why not… But 和 except 前是動(dòng)詞 do 時(shí)，后面出現(xiàn)的動(dòng)詞用不帶 to 的動(dòng)詞不定式。如：He was seen to enter the hall. He asked to be sent to work in Tibet.三、 省to 的動(dòng)詞不定式 情態(tài)動(dòng)詞（除ought 外，ought to） Would rather, had better. 感官動(dòng)詞 see, watch, look at, notice, observe, hear, listen to, smell, feel 等后作賓補(bǔ)，省略 to.注意：在被動(dòng)語態(tài)中 to 不能省略掉。如：He seems to be eating something.（4） 完成進(jìn)行時(shí)：表示動(dòng)作從過去某個(gè)時(shí)間開始，一直延續(xù)到現(xiàn)在，并有可能持續(xù)下去。如：He seems to know this. I hope to see you again. （2） 完成時(shí)：表示的動(dòng)作發(fā)生在謂語動(dòng)詞表示的動(dòng)作之前。 如：To see is to believe. （眼見為實(shí)） 獨(dú)立結(jié)構(gòu)。如：The question is how to put it into practice.My question is when to leave.His dream is to be a doctor.Her work is to look after the babies.注意：，對(duì)應(yīng)的謂語動(dòng)詞用單數(shù)。如：We were very excited to hear the news.I’m glad to see you.（4） 做條件狀語。He came to the school to see his son.（2） 作結(jié)果狀語，表事先沒有預(yù)料到的，要放在句子后面。以便如： I need a pen to write with . (I will wirte with the pen ) (我需要一直鋼筆寫字) I have a little baby to look after .(I must look after the little baby ) (我有一個(gè)嬰兒要照看)作狀語，表示目的、結(jié)果、原因等，有時(shí)還有一些固定搭配的不定式短語，如in order to , so as to, so…as to, such …as to, ….enough to, too…to等。如：I have a lot of work to do.（動(dòng)賓關(guān)系）He is looking for a room to live in.（動(dòng)狀關(guān)系）He is the first person to think of the idea.（主謂關(guān)系）He has got a chance to go abroad.（同位關(guān)系）注意：，不定式用主動(dòng)形式表被動(dòng)。如：They saw the boy fall off the tree. The boy was seen to fall off the tree. (3)help后面作賓語補(bǔ)足語的不定式可以帶to,也可以不帶to. I often help him （to）clean the room. I helped him (to) find his things. 作定語不定式作定語，修飾名詞或代詞，不定式和它所修飾的名詞之間有邏輯上的主謂關(guān)系、動(dòng)狀關(guān)系、同位關(guān)系或動(dòng)賓關(guān)系。Mary took him as her father. 瑪麗把他當(dāng)作自己的父親。注意：（1）有些動(dòng)詞需用 as 短語作補(bǔ)語，像regard, think, believe, take, consider。如：We consider Tom to be one of the best students in our class.The book is believed to be useful.（被動(dòng)語態(tài)） (3) There +不定式。如：I find it necessary to learn a foreign language. 作賓語補(bǔ)足語（1） 動(dòng)詞+賓語+不定式（to do ）。如：He managed to escape from the fire.I find it hard to get along with him.（it 作形式賓語）注：下列動(dòng)詞通常用不定式作賓語：want, try, hope, wish, need, forget, know, promise, refuse, help, decide, begin, start, learn, agree, choose, get等（2） 動(dòng)詞+疑問詞+to , “特殊疑問句+不定式”相當(dāng)于名詞，作賓語。 （2）當(dāng)不定式作主語的句子中又有一個(gè)不定式作表語時(shí)，不能用It is …to…的句型。往往用it 作形式主語，把不定式放在謂語后面。非謂語動(dòng)詞在句中充當(dāng)除謂語以外的句子成分的動(dòng)詞形式叫做非謂語動(dòng)詞。非謂語動(dòng)詞分為三種形式：不定式、動(dòng)名詞和分詞（分詞包括現(xiàn)在分詞和過去分詞）不定式一、 不定式的作用 作主語 不定式作主語時(shí)，謂語用單數(shù)。如：It took us two hours to finish the job.It is impossible for us to get there
