　　1.選a.該題考查定語從句引導詞前介詞的選擇。定語從句可以由“介詞+which/whom”來引導，介詞的選擇取決于從句動詞的搭配關系以及從句本身的意義。本題中which代表前面的one hundred languages,根據句意，其中14種被定為官方語言，這是一種部分與整體的關系，所以關系代詞前面的介詞要用of.

　　2.選d.該題考察非限定性定語從句。觀察句子結構及四個選項可以看出這里需要一個“介詞+關系代詞”的結構引導定語從句，因其先行詞為人(20students)，且從句中需一個表范圍的詞，介詞of表示“在一群人當中有一個或幾個”

　　3.選b.該題考點為“介詞+關系代詞”引導的定語從句。關系代詞which代表goals在從句中作fight for的賓語。

　　4.選c.該題考查such….as引導定語從句。As為關系代詞，在該從句中為賓語。

　　1.A more conclusive answer about life on Mars,past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life.

　　2.The Bush administration seems bent on satisfying the small but vocal group of Americans who oppose stem cell research under any conditions.

　　答案

　　1.【解析】該題考察which引導定語從句的用法。Past or present是插入成分，補充說明life on Mars.which 引導定語從句，修飾conditiona,which在從句中作方式狀語，前面加介詞under.

　　【句意】有關火星上過去和現在是否存在生命的更加確鑿的答案，將向研究人員提供以下方面的珍貴數據，即行星在什么條件下能夠導致最終產生生命的復雜化學反應。

　　2.【解析】該句為主從復合句。主句是the Bush administration seems bent on satisfying the small but vocal group of Americans,定語從句who oppose stem cell research under any conditions來修飾Americans.

　　【句意】少數人呼聲不斷，堅決反對出于任何目的的干細胞研究，布什政府似乎已經屈從于滿足這些人了。

　　1.The road of life is long,but only a few steps are crucial especially during some years_______(當人年輕的時候)

　　2.April Fool’s Day is that special day of the year______(在這一天你可以捉弄別人)

　　答案

　　1.when people are young

　　【解析】該題考察when 引導定語從句的用法。when 在定語從句中充當時間狀語，相當于“in which”

　　2.when you should play a joke on someone

　　【解析】該題考察when 引導的定語從句。When只能對that special day of the year這類表示時間的名詞進行修飾。

　　翻譯：

　　Therefore,with every increase of knowledge and skill,wisdom becomes more necessary,for every such increase augments our capacity for realizing our purposes,and therefore augments our capacity for evil,if our purposes are unwise.

　　【妙譯】因此，隨著知識和技術的增加，更加需要智慧，因為知識和技術的每一次增長都會增強我們到達目標的能力，當然如果我們不智慧，也能增強我們作惡的能力。

　　【點撥】該句為一個復合句，其主干為“wisdom becomes more necessary”。With引導的短語構成伴隨狀語;for 在本句中引導原因狀語從句，在該句原因狀語從句中，包含一個由if引導的條件狀語從句。
