新编四级听力练习 第239期

答案解析：
36. essential
解析：此处需要形容词，注意双写s和词尾tial。
37. amazing
解析：此处是现在分词用作形容词，不可遗漏-ing。注意不要写成形似近音词amusing。
38. enables
解析：此处需要动词作谓语，用法是接不定式作宾语补足语。注意that指代的是this magical time machine，故该谓语动词用第三人称单数。
39. Discovering
解析：此处需要动名词作主语，注意ing。由于此词位于句首，因此要大写首字母D。
40. preserves
解析：此处需要与makes并列的动词，注意开头的p不要漏掉。
41. pursuits
解析：根据one of和all可知此处需要名词复数形式，拼写时注意ur和ui。
42. apologize
解析：根据must可知此处需要动词原形。
43. compromised
解析：根据has been和by可知此处需要过去分词表示被动，所以不要漏写词尾d。
