試題答案及解析：
11. Cneedn’t have done sth.表示做了不必做的事，此句意為：“你真不必寫這么長的文章，老師告訴我們只寫200個詞，可你寫了300個詞。”
12. AB、C選項之所以錯，主要是由于long的位置不對，應(yīng)為：B. Being long used…;C Having long been used…。句子前半部分是狀語，故D也不對。由此可見A是惟一正確的選擇。
13. Cother than 的意思相當(dāng)于except，常用在否定詞之后，如nobody other than…，nothing other than等。本句中與no在一起連用，意為“只有在英國……”。it has been said是插入語。
14. Bas是關(guān)系代詞，引導(dǎo)非限定性定語從句， 其先行詞是measures，相當(dāng)于…as the measures which are taken by the government…，其他幾個詞都是連詞，不能引導(dǎo)定語從句。
15. A句中的第一個空白處需要一個引導(dǎo)名詞性從句的關(guān)系代詞，在從句中做write 的賓語;第二個空白處要填一個修飾way的定語從句的關(guān)系代詞，因此只能選A。注意: 先行詞是way, 引導(dǎo)定語從句的關(guān)系代詞一定不能用how, 可以用in which, 可以用that, 也可以省略不用。
16. Cunless“除非”，從主從句的邏輯關(guān)系上看是惟一正確選擇。句意：“假如發(fā)生了水災(zāi)或地震，且火車、汽車又無法通至災(zāi)區(qū)，除非用飛機空投，否則那里的人們就會餓死�！�
17. Bto become在句中做desire的定語，意為“成為一個著名作家的愿望”，其他結(jié)構(gòu)一般不做desire的定語。
18. B不定式to have been working…做主語scientist的補足語，用完成進行式表示：“這個科學(xué)家已對如此復(fù)雜的問題研究了大約十年，并且還要繼續(xù)研究下去�！�
19. Dtaken在句中做后置定語，修飾majority, 由于與所修飾的詞是動賓關(guān)系，所以應(yīng)用過去分詞，a majority which is taken collectively可以理解為“(把)大多數(shù)人作為一個整體”。
20. A句中but表示轉(zhuǎn)折，后面陳述的是事實情況：“……看錯了問題所以沒答對”。暗指“若不是看錯了題，就會答對而且通過考試”。因此句子前半部分用的是虛擬語氣would have passed。
