2019年高考英語二輪專題復習 動詞的時態和語態
she was sure she would succeed.i thought you would come.把一般將來時中的助動詞變成過去式，便成了過去將來時的表達形式。②表示過去經常發生的動作。 when he was young, he would go swimming.注意：would與used to的區別：would只表示過去，不涉及現在，而used to表示“過去常常”要與現在比較，即現在不是這樣了。11.要求一定時態的固定的句型①was/were doing sth. when…did sth.(正在做某事，這時突然……)i was reading a book when the bell rang.②was/were about to do sth. when…did sth. (正要做某事，這時突然……)we were about to leave when the telephone rang.③it(this) is(will be ) the first/second/third…time+ that…it’s the first time i’ve seen her.we have been there three times.如果句中有比較確定的時間狀語，則服從時間狀語的要求。last year i saw him many times.④it is/has been… since…it is (has been) two weeks since i came here.she said it was five hours since she had finished her work.⑤hardly… when…\no sooner… than…hardly had we got in the crops when it began to rain.i had no sooner come into the room than the door was closed. ⑥it(this) is(will be ) the first/second/third…time+ that…this is the first time i have been here. it'll be the first time i've spoken in public. iii.被動語態的用法被動語態表示句子的主語是動作的承受者，也就是動作的對象，一般說來只有及物動詞才有被動語態。其構成為"be+及物動詞的過去分詞"。助動詞be有人稱、數和時態的變化，其變化規則與be作為連系動詞時完全一樣。含有情態動詞的謂語變化為被動語態時，由"情態動詞（can, may must, have to等）+be +動詞的-ed形式。含有"be going to , be to, used to, be about to"等結構的復合謂語變為被動語態時，其構成為"be going to （be to, used to, be about to）+ be +動詞的-ed形式"構成。1.被動語態的適用范圍①當我們不知道誰是動作的執行者，或者沒有必要指出誰是動作的執行者時。這時不用by短語。this jacket is made of cotton. 這件上衣是棉料的。②為了強調動作的承受者時 visitors are requested not to touch the exhibits. 要求參觀者不可觸摸展品。③出于策略、委婉、禮貌等不提出動作的執行者you are said to be active recently. 據說你最近很活躍。常用于如下句型：it's not known that… ……不得而知 it's said that… 據說……it's reported that… 據報道…… it's not decided that…尚未決定it's believed that… 據認為…… it's announced that…據宣布……2.被動語態的句型①常見句式是：主語（受動者）＋be＋過去分詞＋（by＋施動者）he was scolded by the english teacher.②主語＋get＋過去分詞＋其它成分the boy got drowned last summer./ she got fired because of her faults.
