课时提升作业(十六) 选修6 Unit 1 (建议用时40分钟) . 单项填空 1. (2017·南京模拟)Do you sometimes ignore loved ones because your life is too fast and busy leaving them ________ whether you really love them? A. wonderB. to be wondering C. wondering D. wondered 【解析】选C。考查非谓语动词的用法。句意: 有时你会因为快速和繁忙的生活而忘记你所爱的人, 并让他们疑惑你是否真的还爱他们? 空格处为leave sb. +宾语补足语结构。them与wonder之间为主动关系, 且表示动作正在进行, 故用wondering。 2. Seeing the stranger ________ , the frightened baby couldn’t help ________ crying. A. burst in; bursting into B. break in; burst into C. break in; bursting out D. break into; burst out 【解析】选C。考查固定表达。句意: 这个受惊的孩子看到陌生人破门而入, 忍不住大哭起来。burst out/into, break into均可表示“突然……起来”的意思, 区别在于burst into及break into后必须接名词, 而burst out后须接动名词。break in更强调破门而入。故选C。 【加固训练】 When he fell into the pond, I couldn’t help but burst ________ laughter. |
