Id rather go there. 不愿意。我想去那里。由于would rather表選擇，因 而后可接than，例如：I would rather work on a farm than in a factory.2. 連系動詞 連系動詞構(gòu)成系表結(jié)構(gòu)，說明主語的狀況、性質(zhì)、特征等情況及其與其它詞連用時所表達(dá)的特殊意義。連系動詞，本身有詞義，但不能單獨(dú)用作謂語，后邊必須跟表語（亦稱補(bǔ)語）構(gòu)成系表結(jié)構(gòu)。（1）狀態(tài)系動詞：用來表示主語狀態(tài)，只有be一詞，例如： He is an engineer. 他是一名工程師。（is與補(bǔ)足語一起說明主語的身份。）（2）持續(xù)系動詞：用來表示主語繼續(xù)或保持一種狀況或態(tài)度，主要有keep, remain, stay, lie, stand, 例如：He always keeps silent at meeting. 他開會時總保持沉默。 This matter remains a mystery. 此事仍是一個謎。（3）表像系動詞：用來表示“看起來像”這一概念，主要有seem, appear, look。例如：He looks tired. 他看起來很累。 He seems (to be) very happy. 他看起來很高興。（4）感官系動詞：感官系動詞主要有feel, smell, sound, taste。 例如： This kind of cloth feels very soft. 這種布手感很軟。 This flower smells very sweet. 這朵花聞起來很香。（5）變化系動詞：這些系動詞表示主語變成什么樣。變化系動詞主要有bee, grow, turn, fall, get, go, e, run. 例如：He became mad after that. 自那之后，他瘋了。 The bread went bad within a short time. 那面包沒多長時間就發(fā)霉了。（6）終止系動詞：表示主語已終止動作，主要有prove, turn out等，表達(dá)“證實(shí)”，“變成”之意。例如： The rumor proved false. 這謠言證實(shí)有假。His plan turned out a success. 他的計劃終于成功了。（turn out表終止性結(jié)果）3. 動詞的時態(tài) 動詞的時態(tài)一般分為現(xiàn)在時、過去時、將來時、完成時和進(jìn)行時等：（1）動詞時態(tài)的種類：1）一般現(xiàn)在時，一般過去時，一般將來時，過去將來時ask / asks，asked，shall/will ask，should/would ask 例如：He often gets up at 7 oclock.他常在七點(diǎn)起床。She got up at 6 oclock yesterday.她昨天在六點(diǎn)起床。Tom will get up at 8 oclock tomorrow.湯姆明天將會在八點(diǎn)起床。Mike said that he would e to see me soon.邁克說他不久將會來看我。2）現(xiàn)在進(jìn)行時，過去進(jìn)行時，將來進(jìn)行時am/is/are asking，was/were asking，shall/will be asking，should/would be asking 例如：He is doing homework now. 他現(xiàn)在正在做作業(yè)。She was reading a book at this time yesterday.她昨天這個時候正在讀書。He will be riding on a plane home at this time tomorrow.他明天這個時候?qū)⒄谧w機(jī)回家。3）現(xiàn)在完成時，過去完成時，將來完成時，過去將來完成時have/has asked，had asked，shall/will have asked，should/would have asked例如：So far, he has just finished writing a half of his position.到現(xiàn)在為止，他剛寫完了作文的一半。She had finished her task before we got to her office this morning.今天上午，我們到她辦公室之前她已經(jīng)完成了任務(wù)。He will have finished reading this English story by this time tomorrow.到明天此時他將會看完這本英語小說。She said that Mike would have learned Book 3 of Senior English by this time next year.她說到明年這個時候，邁克將會學(xué)完高中英語必修三。4）現(xiàn)在完成進(jìn)行時，過去完成進(jìn)行時，將來完成進(jìn)行時，過去將來完成進(jìn)行時have/has been asking，had been asking，shall/will have been asking，should/would have been asking例如：Since then, we have been learning American English.從那時以來，我們一直在學(xué)習(xí)美國英語。By 11 oclock last night, he had been learning to set up an internet station.到昨晚十一點(diǎn)以前，他一直在學(xué)習(xí)建網(wǎng)站。By 8 oclock tomorrow, I will have been working on writing a paper.明天八點(diǎn)前，我將一直在寫一篇論文。She said that she would have been working on this project by the end of next month.她說下個月底之前她將一直在做這項(xiàng)工程。（2）現(xiàn)在完成時與一般過去時的區(qū)別：1）現(xiàn)在完成時表示過去發(fā)生的動作或存在的狀況，但和現(xiàn)在有聯(lián)系，強(qiáng)調(diào)的是對現(xiàn)在造成的影響或結(jié)果，它不能同表示過去的時間狀語連用，漢譯英時可加“已經(jīng)”等詞。簡言之，利用過去，說明現(xiàn)在。例如：I have already seen the film directed by the world-famous director.
