解析 答案1. well改為good 這里是作定語，well作副詞用的情況較多，主要是作狀語。
2. sitted 改為sat sit 是不規(guī)則動詞，它的過去式是sat。
3. why改為because 這里引導的是原因狀語從句，所以該用because。
4. sleept改為slept sleep 是不規(guī)則動詞，它的過去式為slept。
5. at 改為in 因莫斯科是個大地方，該用in。
6. were改為was 因主語time 是不可數(shù)名詞，所以謂語動詞該用單數(shù)形式。
7. doesn’t改為didn’t 根據(jù)上下文理解，這里該用過去時態(tài)。
8. on改為in on表示在物體的表面上。
9. anywhere改為everywhere 此處指“到處”。
10. inside改為outside或out 這里指惡劣的天氣里，人們不愿外出。
