This taught Christopher the lesson that anyone who _9_ (try) to improve anything _10_ (have) to learn：Many people dont like new ideas.,答案 1.turned表示對現在的虛擬，用一般過去時。 2.knew一般過去時表示過去的動作。 3.had bought表示“過去的過去”用過去完成時。 4.will/shall make此處用一般將來時表示臨時的決定或安排。 5.was not using過去進行時表示過去某一時刻或某一段時間內正在進行的動作。,6.was finished一般過去時的被動語態(tài)。 7.would like過去將來時，相對于過去某一時刻而言即將發(fā)生的動作或存在的狀態(tài)。 8.have been working用來表示從過去某一時刻開始一直持續(xù)到現在(還要繼續(xù)下去)的動作。 9.tries一般現在時表示經常發(fā)生的、習慣性的動作、客觀真理、科學事實等。 10.has同上題。,.正反探究 1.【誤】Hi，Lucy，you look tired.Im really tired.I have painted the living room all day. 【正】Hi，Lucy，you look tired.Im really tired.I have been painting the living room all day. 解析現在完成進行時態(tài)，表示過去發(fā)生的動作持續(xù)到現在并有可能會繼續(xù)下去。這一點是從時間狀語 all day (整天)看出來的。,2.【誤】Nancy is not coming tonight.But she has promised! 【正】Nancy is not coming tonight.But she promised! 解析南?！按饝獊怼边@個動作應該發(fā)生在過去，是過去作出的承諾，前文已告訴我們“她不來了”，因此諾言已跟現在沒有關系，只是過去的一個動作。,3.【誤】 When Tony phoned me I had just finished my work and started to take a shower. 【正】 When Tony phoned me I had just finished my work and was starting to take a shower. 解析從關鍵信息 I had just finished my work 可以看出是“正要開始洗澡”應該是將來時，was starting 可以表示馬上就要進行的動作；而 started 表示“開始了”。,4.【誤】 I dont really work here；I just help out until the new secretary arrives. 【正】 I dont really work here；I am just helping out until the new secretary arrives. 解析一般現在時表示現在的、經常性的行為或狀態(tài)，而現在進行時表示正在進行的、暫時性的動作。本句是用現在進行時的形式表示將來時，此處表示“我”現在只是在臨時幫忙，是現階段正在進行的動作。,5.很多的鳥類正被人們捕殺。 【誤】 Many birds are killed now. 【正】 Many birds are being killed now. 解析現在進行時的被動語態(tài)結構要完整，不能遺漏其中的助動詞，導致時態(tài)錯誤。,.考點確認 一、?？几鞣N時態(tài)的用法 1.一般現在時 (1)表示經常發(fā)生的、習慣性的動作，通常用usually，often，always，sometimes，every day，once a week等作時間狀語。 I usually have my hair cut once a month.
