答案解析：
36. essential
解析：此處需要形容詞，注意雙寫s和詞尾tial。
37. amazing
解析：此處是現在分詞用作形容詞，不可遺漏-ing。注意不要寫成形似近音詞amusing。
38. enables
解析：此處需要動詞作謂語，用法是接不定式作賓語補足語。注意that指代的是this magical time machine，故該謂語動詞用第三人稱單數。
39. Discovering
解析：此處需要動名詞作主語，注意ing。由于此詞位于句首，因此要大寫首字母D。
40. preserves
解析：此處需要與makes并列的動詞，注意開頭的p不要漏掉。
41. pursuits
解析：根據one of和all可知此處需要名詞復數形式，拼寫時注意ur和ui。
42. apologize
解析：根據must可知此處需要動詞原形。
43. compromised
解析：根據has been和by可知此處需要過去分詞表示被動，所以不要漏寫詞尾d。
