Unit3 Computers單元練習
Ⅰ. 單句語法填空
must learn to consult your feelings and your reason __before__ you reach any decision.
解析：考查連詞與狀語從句。句意：在做任何決定前，你一定要學會考慮自己的感覺與理智。before在……之前，引導時間狀語從句，符合題意。
hing straight after a meal may damage the top of your teeth;__as__ a result, you may feel pain when eating.

d you tell me how to deal __with__ these problems so that I will be able to adapt to the life in Guiyang?
解析：句意：你能告訴我爲了適應貴陽的生活，我應該如何應對這些問題嗎?deal with“處理，應對”，和how連用。
mother thanked the young man again and again, without __whose__help her son would have been killed by the passing car.
解析：考查定語從句關係詞。句意：媽媽一遍又一遍的感謝那個年輕人，要不是他的幫助，她的兒子會被這個路過的車撞死。後面定語從句中，缺少定語，故用關係代詞whose。
made __such__ little progress __that__ his parents felt disappointed.
解析：考查結果狀語從句。中心詞是名詞，所以用such，後面句子中不缺少成分，不能用as而只能用that。
much work did we have to do __that__ we were so exhausted.
解析：由語境可知，本題考查“...”句型。句意爲：我們要做的工作如此多以至於我們都精疲力竭。
8.(2016·天津，7改編)__As__the average age of the population increases, there are more and more old people to care for.
解析：考查連詞。句意：隨着人口平均年齡的增長，越來越多的老人需要照顧。
9.—Why do you look so worried?
—My computer broke down and my essay __has_been_left__(leave) unfinished since.
解析：考查動詞時態和語態。句意爲：——爲什麼你看起來如此着急呢?——我的電腦壞了，而且我的論文還沒有完成。根據題幹中的時間狀語詞since可知，此處應用現在完成時，而且主語my essay和謂語動詞之間是動賓關係。
nderstandings __arising__(arise) from lack of social communication, unless __handled__(handle) properly, may lead to serious problems.
解析：考查非謂語動詞。句意：由於缺乏社會交流而造成的誤解，如果得不到恰當的處理，可能會導致嚴重的問題。第一空，misunderstandings和arise爲邏輯上的主謂關係，所以用arise的現在分詞形式，arise from意爲“由……產生”。第二空，handle和misunderstandings爲邏輯上的動賓關係，所以用handle的過去分詞形式。
won't start the work until all the preparations have__been_made__(make).
解析：本題考查動詞的時態和語態。句意：直到所有的準備工作都做完了，我們纔開始工作。根據主句中的關鍵詞語won't start(不會開始)是一般將來時知，until引導的時間狀語從句用一般現在時或現在完成時代替將來時。
'd better write down her phone number before you __forget__ (forget) it.
解析：句意：趁着還沒有忘記，你最好把她的電話號碼寫下來。before本意是“在……之前”，在句中引導時間狀語從句，根據具體的語境在句中可譯爲“趁着……，以免……”，從句中用一般現在時態表示將來的動作。根據語境可知forget爲將來的動作，故此處用一般現在時表示將來。
e intelligent people can often __simplify__(simple) the complex, a fool is more likely to complicate the simple.
解析：根據While可知，前後句是轉折關係。句意：聰明的人可以簡化複雜的事情，愚蠢的人使簡單的事情複雜化。simplify簡化。
thinks it won't be long__before__he is ready for his new job.
解析：句意：John認爲用不了多久他就會爲自己的新工作做好準備。It won't be long before...是個固定句型，意爲“用不了多久就……”。
