(1)從前，一個富人不識字，別人寫張字條向他借牛，他假裝看了看后說，“我知道了。回去告訴你的主人，我馬上自己過去。”

31. any。與前面的didn’t構成完全否定，即“他不識字”。

33. a。意為“寫了一張條子”，表示“一張”用不定冠詞。

34. it。指代the note。

35. After。仆人給了富人條子之后，他才能假裝看。表示“在……之后”，用連詞after。

36. the。指前文提到的不識字的“那個”富人。

37. to be reading。因pretend后要求接不定式;又由after a while可知，他“假裝在看”，可見要用不定式的進行式。

38. your。這是祈使句，意為“你回去告訴你的主人”。

39. will go。“告訴你的主人，我就去”，“去”應為將來的動作。這是臨時的決定，用will 加動詞原形表示將來。

31. that。句式搭配:so...that...(如此……以致……)。

32. After。表示“過了幾個月后”，填介詞after。

31. leaving。因本句已有謂語，故用非謂語動詞leaving作結果狀語。

32. on。paper 為先行詞，關系代詞 “which”代替了它，表示“在紙上”，which前應加介詞on。

33. An。honest以發元音開頭，表示“一個”誠實的女孩時，應用an。

34. what。told 的直接賓語為賓語從句，而賓語從句中缺了一個充當賓語的連接詞，因此該用what引導賓語從句。

35. to say。在easy， difficult， hard 等形容詞后的動詞，要用動詞不定式。

36. it。it在此代替了前面的the chance。

37. won。and并列了兩句子，前句用了過去式sat，因此后句也應用win的過去式won。

38. but。前句與后句因形成轉折關系，故用but來連接。

34. else。意思是，我除了用磚頭打你的車，讓你停下來，以便幫我把我的哥哥坐回到輪椅上外，我別無他法。因此說“我不知道我還能怎么辦?”else通常用在what， where等疑問詞后或something， anything等復合不定代詞的后面，表示“別的”。

35. is hurt。hurt作及物動詞，意為“使……受傷，傷害……”;作不及物動詞，意為“感到疼痛”。本句中的hurt應為及物動詞，他現在“受傷了”，故用一般現在時的被動語態。

36. for。“對”我來說，太重了。

37. Moved。因he與move是被動關系，故用過去分詞作狀語，表示原因。

38. checking。因he與check是主動關系，用現在分詞作狀語，表示伴隨狀況。

32. its。作表語的名詞前應當填限定語，由句意可知city life也有它自身的問題，故填its。

33. to mention。搭配:not to mention更不用說。

34. Another。搭配:one...another.... 一個……另一個……。

35. Although。因I have...與I seldom use...是兩個句子，之間沒有句號或分號，此處必定填連接詞;由兩句之間的邏輯意義可知，要填表示“雖然，盡管”的Although。
