答案解析：
36. aggravates
解析：根據(jù)本句的主語及整篇文章的時(shí)態(tài)來看，可知此處需要填入動(dòng)詞的第三人稱單數(shù)形式，作句子的謂語，aggravate“加重”，注意要雙寫s。
37. acquire
解析：空格前的情態(tài)動(dòng)詞may表明該詞應(yīng)該是動(dòng)詞原形，acquire“獲得”，注意不要漏掉中間的字母c。
38. relief
解析：填入的詞與benefit并列，因此此處需要一個(gè)名詞，可以根據(jù)發(fā)音規(guī)則拼寫。
39. manual
解析：此處需要填入形容詞，修飾labourer，manual labourer意為“體力勞動(dòng)者”。
40. sweat
解析：此處應(yīng)該填寫一個(gè)名詞，和effort并列，sweat“汗水”，此詞很好拼寫。
41. professional
解析：根據(jù)并列結(jié)構(gòu)及空格前的定冠詞the，可知此處應(yīng)填寫名詞，注意雙寫s。
42. trivial
解析：修飾名詞往往用形容詞。trivial指“瑣碎的”。
43. rational
解析：根據(jù)上下文，此處應(yīng)該填寫與hard-working，useful并列的褒義形容詞，rational“明事理的”。
44. 標(biāo)準(zhǔn)答案：first, those whose work is work and whose pleasure is pleasure; and secondly, those whose work and pleasure are one
聽音關(guān)鍵：work is work，pleasure is pleasure，work and pleasure，one
答案重構(gòu)：first, those whose work and pleasure are divided, and secondly, those whose work and pleasure are one
畫龍點(diǎn)睛：由本段第一句可預(yù)測(cè)本句是對(duì)兩種人的詳細(xì)介紹。本句關(guān)鍵是理解幾個(gè)定語從句的意思，前半句的定語從句可簡(jiǎn)化成whose work and pleasure are divided。
45. 標(biāo)準(zhǔn)答案：The long hours in the office or the factory bring with them as their reward
聽音關(guān)鍵：long hours，office，factory，bring，as，their reward
畫龍點(diǎn)睛：該句結(jié)構(gòu)及用詞都不難，不建議改寫，原詞照搬即可。
46. 標(biāo)準(zhǔn)答案：Their life is a natural harmony. For them the working hours are never long enough
聽音關(guān)鍵：life，natural harmony，working hours，never，long enough
答案重構(gòu)：Their life is a natural harmony and their working hours are never long enough.
畫龍點(diǎn)睛：該句由兩個(gè)簡(jiǎn)單句構(gòu)成，可以將其合并成一個(gè)并列句，層次可更清晰，語句也更簡(jiǎn)潔。
