高考難題解析：

1.Most animals have little connection with _______ animals _____ different kind unless they kill them for food.

A. the; a B. 不填; a C. the; the D. 不填; the

答案：B  通過率：26％

試題分析：本題測試的是冠詞在日常生活情景中的使用能力。此題最大的難點在于：冠詞的語法規則無法完成冠詞使用能力的培養。完成此題的“訣竅”在于具備較強的閱讀理解能力；只有讀懂此題的內容，才能作出比較準確的翻譯。此題可以這樣翻譯：“大多數動物之間沒有什么關系，除非它們（即：某一種動物）以另一種動物為食。”“大多數動物”自然是“不加定冠詞的多數名詞的泛指”，而“某一種動物”或“另一種動物”則自然是“加不定冠詞的單數名詞”。只有這樣，才可能作出正確的選擇。

2._______ production up by 60%, the company has had another excellent year .

A. As B. For C. With D. Through

答案：C  通過率：42％

試題分析：本題測試的是介詞在日常生活情景中的使用能力。此題最大的難點在于：A.As            B.For  C.With  D.Through少四個選項，就個體詞義而言，都表示“原因”，但是在此題的具體情景中，只有C.With無論在句型上（with + 名詞noun + 介詞prep./或形容詞adj. ）還是內容上（具有“伴隨時間接原因”的含義）都是最佳選項。這個句子可以翻譯成：“隨著生產量的提高，到達60％，該公司又經歷了一個業績大好的年頭。”

3.I’ve worked with children before, so I know what ______ in my new job.

A. expected B. to expect C. to be expecting D. expects

答案：B  通過率：34％

試題分析：本題測試的是動詞不定式在日常生活情景中的使用能力。完成此題的關鍵在于：對于know what to expect/where to go/who to see /when to begin /why to do so/how to do it        這類語句的熟練掌握。當然，要做到這一點，大量的口筆語實踐是必不可少的。

4.------- How are you today ?

------- 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

答案：D   通過率：48

試題分析：本題測試的是動詞時態在日常生活情景中的使用能力。完成此題的關鍵在于：不要過分依賴有關時態教學的語法規則。首先必須在詞義上理解清楚。只要將這個對話翻譯成漢語，就能夠找到正確選項：

------你今天這么樣啊？

------哎呀，好久沒有像今無這樣難受了。

這句譯文使人想起“（I）haven’t seen you for ages.”（“好久沒有見到你了。”）

這兩句話使用的不都是現在完成時嗎？

5.The WTO cannot live up to its name _____ it does not include a country that is home to one fifth of mankind.

A. as long as B. while C. if D. even though

答案：C    通過率：46％

試題分析：本題測試的是連詞與連詞短語的使用能力。完成此題不僅要能夠熟練使用A.as long as   B.while   C.If    D.even though等四個詞語，而且還要具備“閱讀熟詞新義”的能力。因為這個句子雖然不長，但是卻包含live up to…（配得上…，be home to…（是…的家園）等等“熟詞新義”；沒有“閱讀熟詞新義”的能力必然會有失誤。此外，如果，考生對于類似“中國人口占世界五分之一，世貿組織沒有中國，該組織本身就會名不副實。”的說法十分熟悉的話，也有助于選好此題的最佳選項社（條件從句）。

6.The managers discussed the plan that they would like to see _______ the next year.

A. carry out B. carrying out C. carried out D. to carry out

答案：C  通過率：26％

試題分析：本題測試的是在特定的上下文中使用過去分詞的能力。要完成此題必須能夠熟練而準確地確定全句各個詞語的邏輯關系（主體與客體關系，主動與被動關系，語句層次關系），從而翻譯成比較準確的漢語：“經理們討論了這個計劃，大家都希望明年能夠看到這個計劃能夠成為現實（被付諸實施）。”既然是“被付諸實施”，當然要選“被動語態”的 C. carried out.

7.--------Why don’t we take a little break ?

-------- Didn’t we just have ______ ?

A. it B. that C. one D. this

答案：C  通過率：26％

試題分析：本題測試的是在特定的上下文中代詞的習慣用法。要完成此題必須具備較豐富的英語使用實踐經驗，否則，一般“泛泛”的語法規則是無法指導考生順利完成此題的。
