16、行時，而 when 和as般不這么用。John was watching TV while his wife was talking with a neighbour overthe phone.Just as I was leaving the house, you came in.when也可以引導比較短暫的動作，while和as則一般不行。We were having supper when the lights went out. （go out熄滅 ）t find you anywhere.過去進行時往往與 表示一段時間 的狀語連用，如 all morning ， all night

17、 ， all day ， all evening ， the whole week 等，表示這段時間一直在干什么。What were you doing all evening? I couldn 過去動作同時發(fā)生的時態(tài) 過去兩個動作同時發(fā)生 , 習慣上一個用一般過去時 , 另一個用過去進行 時；動作長用過去進行時 , 動作短用一般過去時 ; 分工的情況 , 動作的開始時 間和結束時間幾乎相同 , 均用過去進行時 ;I was listening to the radio, my sister was dancing.When my mother was doing the housework

18、, my father was watching TV. 兩個動作在同時段進行 , 在不同時間結束 , 先發(fā)生的動作未結束 , 另一 個動作發(fā)生 , 先發(fā)生的動作用進行時態(tài) , 另一個動作用過去時 .When I was opening the door, the telephone rang.先開門When the telephone was ringing, I opened the door.電話先響 瞬間動詞(如： arrive )沒有進行時態(tài) , 所以兩個動作同時發(fā)生 , 延續(xù)性 動詞用進行時態(tài) , 瞬間動詞使用過去時態(tài) .When he arrived, I was having

19、dinner.I am arriving 進行時態(tài)表示將要ExercisesD1 As my father (leave) the house, the postman (arrive).was leaving ； arrived( 兩個瞬間動詞同時發(fā)生可能性很小 , 應具體分析 , 故 用進行時態(tài)表將來 )5 While mother (prepare) lunch, Janet (set) the table.set the table 擺桌子 was preparing ； set【 Special Difficulties】 短語動詞中的小品詞：許多動詞加上介詞或副詞后就會改變詞義，這

20、些介詞 和副詞通常被稱為小品詞。它們沒有詞形的變化。有些小品詞既可以作介詞又可以作副詞。判斷一個小品詞是副詞還是介詞要看小品詞有沒有帶賓語。有賓語的是介詞，沒有賓語的是副詞，介詞的位置相對固定，不能變動。 vi.&vt.+ prep./adv.+賓語(n.)
