His dream is to be a doctor. 五、作定語 不定式作表語表示具體動作或將來動作;動名詞作表語表示抽象的一般行為。 注意: 1) 其他系動詞如,look,appear等也可用于此句型。 c. It39。s easy (for me) to do that. 我做這事太容易了 b. It39。 有些動詞需用as 短語做補語,如regard, think believe, take, consider. We regard Tom as our best teacher. 我們認為湯姆是我們最好的老師。而C為現(xiàn)在完成時,發(fā)明為點動詞一般不用完成時,且此處也不強調對現(xiàn)在的影響,因此不選C。現(xiàn)在分詞表達主動,也表達正在進行,過去分詞表達被動。 Find 的特殊用法: Find 后可用分詞做賓補,或先加形式賓語,再加形容詞,最后加帶to 的動詞不定式。 c. The question is how to put it into practice. 問題是怎樣把它付諸實施。 d. I want you to talk to Tom. 我想讓你和湯姆談話。 I happen to know the answer to your question. 我碰巧知道你那道問題的答案。 3) 進行式:表示動作正在進行,與謂語動詞表示的動作同時發(fā)生。 2) 完成式:表示的動作發(fā)生在謂語動詞表示的動作之前。這一使動者我們稱之為邏輯主語,其形式如下: 時態(tài)主動形式被動形式一般式(not)to do(not)to be done完成式(not)to have done (not)to have been done進行式(not)to be doing?完成進行式(not)to have been doing?1) 一般式:一般現(xiàn)在時表示的動詞,有時與謂語動詞表示的動作同時發(fā)生,有時發(fā)生在謂語動詞的動作之后。 動詞不定式指由to 加上動詞原形(而且只能是動詞原形)所構成的一種非限定性動詞,但在有些情況下to可以省略。它被叫做不定式,是因為動詞不被限定,或者說不被詞形變化所局限。 動詞不定式及其短語還可以有自己的賓語、狀語,雖然動詞不定式在語法上沒有表面上的直接主語,但它表達的意義是動作,這一動作一定由使動者發(fā)出。ll see you again. 我希望再見到你。 He seems to have caught a cold. 他似乎感冒了。 不定式在句中的成分一、作賓語 1)動詞+ 不定式afford,aim,appear,agree,arrange,ask,be,decide,bother,care,choose,e,dare,demand,desire,determine,expect,elect,endeavor,hope,fail,happen,help,hesitate,learn,long,mean,manage,offer,ought,plan,prepare,pretend,promise,refuse,seem,tend,wait,wish.
