答案解析：

36. typically解析：通过预读可以发现这句话的主、谓、宾语都完整，而且要听写的词在动词前，可以判断出此处填写一个副词。但词尾ly容易被忽略。考生可通过分析句子成分，更加准确判断词汇的形式。第2个字母y不要误写成i。

37. connected解析：be connected to是固定搭配，不要忘了在connect后加-ed。

38. accompanies解析：由于主语是单数形式，因此即使没有听出ies也要将其补充完整，而不能写成原形accompany。

39. link解析：通过预读从"between... and... "可以知道本句讨论的应是“睡眠和腰间赘肉、双下巴等之间的关系”，因此是link，而不是leak（泄露）。

40. produced解析：要填写的词汇在副词后，与normally和during deep sleep一同作hormone（荷尔蒙）的后置定语，在意义上有被动的含义，故要用produced，-ed不要忘了。

41. issue解析：issue为四级重要词汇，在此意为“（杂志的某一）期”，可以根据前面的August和后面的Journal预测到，关键是要拼写正确，注意双写s。

42. associated解析：不要写成：associate。be associated with为固定搭配，意思是：与……相互联系。即使没听出来，-ed也不应漏掉。

43. elderly解析：elderly a.过了中年的，稍老的。the elderly指老年人。

44. 标准答案：Between age 25 and 35, the deep sleep drops to about 12 percent听音关键：age 25 and 35，deep sleep，about 12 percent答案重构：1). When one is between age 25 and 35, his deep sleep reduces to about 12 percent2). The deep sleep for men of 25 to 35 falls to about 12%画龙点睛：此句比较简单，抓住：25-35，deep sleep，12 percent，就容易完成。drop表示“下降”，可以用reduce，decrease，fall等词替换。若改变句型，变换主语，则需要注意主谓一致。

45. 标准答案：after age 50, men's total sleep declines by about 27 minutes per decade of age听音关键：50，total sleep declines，27 minutes per decade答案重构：1). after age 50, their total sleep will reduce about 27 minutes for every ten years2). after 50, their total sleep will keep declining at the rate of about 27 minutes every ten years画龙点睛：per decade of age意思是“每10年”。如果怕写错decade一词，可换成every ten years。

46. 标准答案：Exercising at least 20 minutes three or four times a week is also helpful听音关键：Exercising，20 minutes three or four times a week，helpful答案重构：1). It's helpful to do exercises for over 20 minutes three or four times a week2). Exercising regularly-over 20 minutes each time, three or four times a week-also helps画龙点睛：本句的难点在于完整地听写出at least 20 minutes three or four times a week。没有生词，只是担心内容会有缺漏。
