答案：37 D 38 B 39 A 40 B

我要详细的解说谢谢！

Answer 1

解释如下：
37. must have done 是对过去的推测，所以选D，表示一般过去时的反意疑问句didn't it。
“根据他所投诉的”不是主句，不能反问这一点，所以不能选didn't he。

38. 越野滑雪是一项运动，在运动中人们可以享受快乐与冒险。能表达“在……中”当然是关系副词where。

39. 意思：作一个涉及到未来的恰当的决定将很可能影响我们的生活。
concerning是个介词，意思是“关系到”。另例：
I have got a letter concerning my overseas studies. (我收到一封涉及到我留学的信。)

40. 意思：你认为得有多长时间公交车才会到来？---不到5分钟。
表达“公交车到来之前得等多长时间”，所以是 before。

Answer 2

37 D 这是对过去发生的事的肯定判断，故用过去时 反问。
38 B 这是where引导的定语从句修饰sport = they can enjoy excitement and adventure in the sport.
39 A 前面是动名词短语作主语 concerning the future 是现在分词作动名词 的状语
40 B 这是before句型 经常翻译成 。。。之后
你认为 多久之后 公交车才能到达这里？
