I. 单项选择（15分）
1. Henry wants to be______ actor like Jackie Chan in the future.
A. a B. an C. the D. 不填
【解析】选B。句意：亨利将来想成为一名演员，就像成龙那样。表示泛指，意为“一”，应用不定冠词a或an，且actor是以元音音素开头的单词，故用an。
2. —Excuse me. Is this your English book?
—No, it isn’t. ______ is in my backpack.
A. I B. My C. Me D. Mine
【解析】选D。由句意知空缺处单词应意为“我的”，且在句中作主语，故应用名词性物主代词。mine“我的”，是名词性物主代词，此处mine=my English book。故D项符合。
3. ［09哈尔滨中考］A new study proves a ______ walk every day is enough to keep people away from becoming fat.
A. 30-minute B. 30 minute’s C. 30-minutes
