No，he _(change)his mind after a phone call at the last minute. 6.(2015陜西卷)At college，Barack Obama didnt know that he _(become)the first black president of the United States of America. 7.(2015四川卷)More expressways_(build)in Sichuan soon to promote the local economy.,答案 1.were句意：價格過去和現在仍然過高的原因是復雜的，沒有簡短的討論可以令人滿意地解釋這個問題。根據and still are可以推斷出空白處是對過去時態的考查。 2.will find句意：在你瀏覽這本書時，你會發現經歷二戰的數百萬人的經歷各不相同。as引導時間狀語從句，意思是“當的時候”，在從句中使用的是一般現在時，所以主句使用一般將來時，即所謂“主將從現”，主句使用一般將來時，從句使用一般現在時。,3.will call句意：Dr.Jackson現在不在他的辦公室里。好的，過一會兒我再給他打電話。由句中的later可知此處要用一般將來時。 4.was going to句意：愛因斯坦出生于1879年。小時候，幾乎沒有人想到他會成為一個其理論將會改變世界的科學家。根據語境可知，此處要用過去將來時。 5.changed句意：彼特要來嗎？不，當接到一個電話后，他最后時刻改變了主意。句中的after a phone call at the last minute 表明動作發生在過去，故用一般過去時。,6.was to become/would become句意：大學的時候，奧巴馬不知道他會成為美國的第一位黑人總統。表示“注定成為”要用be to do；主句是一般過去時，所以從句要用過去將來時。 7.will be built句意：四川將建設更多的高速公路以促進當地的經濟(發展)。根據時間狀語soon可知，此空為將來時；主語expressways和動詞build之間為動賓關系，故要用一般將來時的被動形式。,.語境感悟 用所給詞的適當形式完成下列短文，然后朗讀或背誦，體會動詞時態、語態的用法。 When he was a little boy，Christopher Cockerell once watched his mother turning the wheel of her sewing-machine with her hand. “Wouldnt it work quickly if the machine _1_ (turn) the wheel for you？”he asked. “I suppose it would，”said his mother，without paying any attention to him.,Christopher _2_ (know) she always had a lot of work，and he wanted to help.In his bedroom there was a toy steam-engine which his father _3_ (buy) him as a gift.“I _4_ (make) better use of it，”little Christopher said to himself.So，when his mother _5_ (not use) her sewing-machine，he fixed the toy steam-engine onto it.When the job _6_ (finish)，he was quite pleased，thinking his mother _7_ (like) it.,“Very clever，”his mother said，when she saw it.Then she sat down and went on turning the wheel by hand.“I _8_ (work) like this for too many years，” she explained. 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。 7.would like過去將來時，相對于過去某一時刻而言即將發生的動作或存在的狀態。 8.have been working用來表示從過去某一時刻開始一直持續到現在(還要繼續下去)的動作。 9.tries一般現在時表示經常發生的、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，表示過去發生的動作持續到現在并有可能會繼續下去。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，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結構要完整，不能遺漏其中的助動詞，導致時態錯誤。,.考點確認 一、?？几鞣N時態的用法 1.一般現在時 (1)表示經常發生的、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.
