答案解析：

Section C Compound Dictation

36. mysterious

解析：此处需要与vast，deep并列的形容词，mysterious意为“神秘的”。注意拼写，特别是第2个字母。中间含有y发出的/I/音的多音节单词常考，另如typical。

37. coupled

解析：couple with是固定搭配，即使听不清最后的/d/，根据语法知识也应该补上。另外，不可漏写字母o。

38. ruining

解析：与killing并列，应该用-ing形式。另外，不能误听成ruling或running。

39. means

解析：此处需要可以与of搭配的名词，表示“生活手段”，means单复数同形。

40. percent

解析：此处表示百分比，此词在数词后面不需要复数形式。2003年6月大学英语六级改错中考过。

41. species

解析：此处需要名词，species单复数同形。注意元音字母及组合。

42. ensure

解析：此处需要动词表示“保证，确保”，ensure一般不与insure替换，后者主要指“保险”。还要与assure区分开，后者往往以人作宾语，常使用assure sb. of sth.或assure sb. that...句型。

43. average

解析：an average of为固定搭配，意思是“平均”，后面多接数字。

44. When you consider that equals a quarter of the world's catch, you begin to see the size of the problem

听音关键：equals a quarter, world's catch, size, problem

答案重构：If you know that is a quarter of the world's catch, you begin to realize how serious the problem is

画龙点睛：关键是以数字体现问题。此句为主从复合句，结构要正确。另外，the world's的所有格形式要正确；catch在本句中作名词，意为“捕鱼量”。根据上下文，被误捞上来的海洋生物占了总捕捞量的四分之一（a quarter of），说明问题的规模已经很大，即后文的the size of the problem。

45. 标准答案：some countries are beginning to deal with this problem, but it's vital we find the rational ways of fishing

听音关键：countries, deal with, vital, find, rational ways, fishing

答案重构：some countries have begun to deal with the problem, but it's vital to find the rational ways of fishing

画龙点睛：原句使用了虚拟语气，在"it's vital (that)..."结构中，that后面的从句中要用(should+)动词原形。也可以改为不定式作主语。

46. 标准答案：It would make sense to give the fish enough time to recover, grow to full size and reproduce

听音关键：fish, enough time, recover, grow, reproduce

答案重构：It's sensible that we allow the fish enough time to recover, grow big enough and reproduce

画龙点睛：注意make sense这个短语；此外，要记住enough...to这一结构后面的三个并列动词。句子结构可以在理解的基础上自行重组。
