　　1. Crather than 表示對比，在意思上前后形成對照：take advantage of your generosity…rather than become appreciative of your kindness意為“利用你的慷慨，而不是理解你的好意”。另外，rather than在結構上起并列作用，使take advantage與become appreciative平行。

　　2. Cthe one替代the age，還原為：…but must write for the age in which he lives and the ages which are to follow。

　　3. Bin which在定語(yǔ)從句中做狀語(yǔ)，相當于in the balance of nature (many square miles of…)。

　　4. Cthat引導case的同位語(yǔ)從句，其他連接詞都不合適。

　　5. Bfor連接一個(gè)原因分句，對前面的推測做原因上的解釋。請考生記�。簾o(wú)論從邏輯推理還是從語(yǔ)法規則上看，只要前面是表示推測的句子，后面大都用for連接后一句，而不用其他連詞。

　　6. Bthere being 做介詞of 的賓語(yǔ)，如果是介詞for，則用there to be。

　　7. C分詞短語(yǔ)做伴隨狀語(yǔ)，形容詞open在分詞短語(yǔ)中做補語(yǔ)，表示狀態(tài)，不用過(guò)去分詞，所以D不正確。

　　8. B此句是含蓄虛擬語(yǔ)氣句，暗含的假設條件為：if they hadn’t happened to be short of hands。故應選B。

　　9. Cmay have done“(不管我們白天)可能做了些什么”，符合句意。should have done“本該做(但實(shí)際未做)”;would have done表示與過(guò)去相反的假設;must have done是對已發(fā)生的情況作肯定推測。

　　10. A句中too late相當于too late to catch the train，所以選其他詞不合適。
