一、It's+籠統(tǒng)的時(shí)間time(about time/high time)+that clause……該做……。
分析:該句型常用來表達(dá)“是某人該做某事的時(shí)候了?!睆木渲^語動(dòng)詞用虛擬語氣did/should do。且should不省略。例如:It's time that we took/should do some mea-sures to settle the problem,是我們?cè)摬扇〈胧┙鉀Q那個(gè)問題的時(shí)候了。
二、It's+泛指的時(shí)間段+when clause
分析:該句型中的時(shí)間通常是不具體的時(shí)間,如某一時(shí)期、某一時(shí)代或時(shí)刻等。其中when引導(dǎo)的是一個(gè)定語從句。如;It's atime when a large amount of reptilescontrolled the earth,那是一個(gè)很多爬行類動(dòng)物橫行地球的時(shí)代。
三、It's+具體的時(shí)間段+since clause,從句謂語動(dòng)詞通常用一般過去時(shí)。例如:
It's two years since he joined the army(=Two years has passed since he joinedthe army)他參軍兩年了。
分析:在該句型中,如果從句的謂語動(dòng)詞是短暫性動(dòng)詞,該動(dòng)作從它開始起算起,如上例。若從句的謂語動(dòng)詞是延續(xù)性動(dòng)詞,則動(dòng)作從它結(jié)束時(shí)算起。
四、It+be+時(shí)間段+before clause
1.It will/is going to/would,情態(tài)動(dòng)詞(表推測(cè))+be+時(shí)間段+before clause
分析:該句型中,主句時(shí)態(tài)是一般將來時(shí),從句為before從旬,且時(shí)態(tài)為一般現(xiàn)在時(shí)。譯為“要不多久就……”或“再過……就……”。例如:It will be two months be-forethe year 2010 arrives,再過兩個(gè)月。2010年就要到了。
2.hwas+時(shí)間段+before clause
分析:該句型中。主句時(shí)態(tài)是一般過去時(shí),從句為before從句。譯為“過了多久才……”例如:It was three days before he telephoned me,三天后他才給我打電話。
3.It would be+時(shí)間段+before clause
分析:該句型通常用在間接引語里。譯為“過不多久就,在過多久就……”。例如:
She said it would be three months before the new year came,她說再過三個(gè)月就是新年了。
五、It's+時(shí)間點(diǎn)+clause
1.It's+時(shí)間點(diǎn)+定語從句
2.It's+時(shí)間點(diǎn)+that clause(強(qiáng)調(diào)句型)
分析:在這個(gè)句型里,判斷方法是:去It's,若剩下部分為完整的句子,則用that引導(dǎo),是強(qiáng)調(diào)句型。如:It's yesterday that he left here for Beijing,反之是定語從句,用關(guān)系代詞或關(guān)系副詞引導(dǎo)。如:
It's 6:00 when he left here for Beijing this morning,
It's 6:00 at which be left here for Beijing this morning,
It's 6:00 that/which/不填he left here for Beijing this moming,
六、It's+prep.+時(shí)間點(diǎn)+that clause
分析:在這個(gè)句型里,由于prep.+時(shí)間點(diǎn)能夠單獨(dú)做狀語,所以該句型是強(qiáng)調(diào)句型。例如:It's at five o'clock this morning that I came to Dalian by train我今天5點(diǎn)乘火車到大連。
七、It's+介詞短語+attribute clause+強(qiáng)調(diào)句型
分析:該句型屬于It's+介詞短語+強(qiáng)調(diào)句型。常見的選擇題的解題規(guī)律是“先捂后放”原則。即在確定第一個(gè)空白處的答案時(shí),先捂住介詞(只看表示時(shí)間/地點(diǎn),原因或方式的名詞)再進(jìn)行判斷,就可較準(zhǔn)確地確定為定語從旬;在確定第二個(gè)空白處的答案時(shí),不要捂住介詞再進(jìn)行判斷,很易判斷為強(qiáng)調(diào)句型。例如:
It's at nine o'clockI arrived at the stationI met him
A.that;whenB.that;that
C.when;whenD.when;that答案:D
八、It+be+tlle+序數(shù)詞+time+that clause
1.It is the fist/second…time that clause
分析:在這個(gè)句型里,由于主句的謂語動(dòng)詞是is,所以從句謂語動(dòng)詞的時(shí)態(tài)用現(xiàn)在完成時(shí)。例如:It's the second time that I've been here,這是我第二次來這里。
2.It will be the first/second…time that clallse
分析:在這個(gè)句型里,由于主旬的謂語動(dòng)詞是一般將來時(shí),所以從句謂語動(dòng)詞的時(shí)態(tài)用現(xiàn)在完成時(shí)。例如:It will be the first time that I've spoken French in pub-lic這將是我第一次在公開場(chǎng)合說法語。
3.It was the first/second…time that clause
分析:在這個(gè)句型里。由于主句的謂語動(dòng)詞是一般過去時(shí),所以從句謂語動(dòng)詞的時(shí)態(tài)用過去完成時(shí)。例如:It was the third time that I hadn't worked on a Saturday那是我第三次在星期六不工作。
九、It's for the first,second…time that clause,
分析:在這個(gè)句型里,由于forthefirst/second…time能夠單獨(dú)做狀語,所以該句型是強(qiáng)調(diào)句型。例如:It's for the second time that I came to Dalian,這是我第二次來大連。
