Unit3 Fairness For All
解析：問“離開”發(fā)生在過去什么時(shí)候，是一般過去的事實(shí)。故選d。
28. —the window is dirty. —i know. it _______for weeks. (廣西)
a. hasn’t cleaned b. didn’t clean c. wasn’t cleaned d. hasn’t been cleaned
解析：表示從過去延續(xù)到現(xiàn)在的狀態(tài)，有是“被動”。故選d。
29. —how are you today? (全國)
—oh, i ______as ill as i do now for a very long time.
a. didn’t feel b. wasn’t feeling c. don’t feel d. haven’t felt.
解析：談過去的感受與現(xiàn)在的聯(lián)系。故選d。
30. i _____ you not to move my dictionary; now i can’t find it. (吉林)
a. asked b. ask c. was asking d. had asked
解析：該句表示過去的事實(shí)。故選a。
4. 過去將來時(shí)： 表示從過去某一時(shí)刻看那以后將要發(fā)生的動作或存在的狀態(tài)。由 “would+動詞原形”構(gòu)成。the weather report said there would be strong winds.
辨析：強(qiáng)調(diào)今昔對比用used to do；would do表達(dá)過去反復(fù)發(fā)生的動作,“過去經(jīng)常”。比如：
as soon as she got up in the morning, she would make herself a cup of tea.
charles would always smoke his pipe after dinner.
when i was in australia, she would come to see us on weekends.
now and then he would sit under the tree reading.
真題：—what were you doing when tony phoned you? (天津)
—i had just finished my work and _____ to take a shower.
a. had started b. started c. have started d. was starting
解析：“我”在tony給我電話時(shí)就完成了（had finished）作業(yè)，正準(zhǔn)備要去沖涼，所以是過去將來。備選答案中只有was starting(過去進(jìn)行時(shí)態(tài))表示過去將來。故選d。
5. 現(xiàn)在進(jìn)行時(shí)：
a) 表達(dá)目前正發(fā)生或存在的短暫性的動作或狀態(tài)。比如：
someone is walking towards the house.
bob and i are having golf lessons.
2) 少數(shù)表示動態(tài)動作的動詞現(xiàn)在進(jìn)行時(shí)態(tài)，可表示將來的計(jì)劃，即最近的將來要進(jìn)行的事。（常見的有g(shù)o, come, stay, arrive, leave, start, fly, stop, take等）比如：
i am going up to london, can’t you see?
i am taking my mum to holiday in florida this summer.
