Unit 4 单元语法突破专项训练-四年级英语上学期（译林版三起）

Unit4 I can play basketball 单元语法突破专项训练 ※练习之前必看 重点语法 1、“Don’t...”句型 Don’t be sad, Bobby. 别难过，波比。 【解析】这是由Don’t引导的否定祈使句，它是由在肯定祈使句的动词前面加上Don’t构成的。“Don’t+动词原形”意为“不要……”。 【例句】Don’t talk in the library. 不要在图书馆里说话。 2、询问他人是否能做某事用“Can ...?” ——Can you play basketball, Wang Bing?你会打篮球吗，王兵？ ——Yes, I can.是的，我会。 【解析】当我们想知道别人有没有能力做某事时，可以用“Can+主语+动词原形+其他?”的句型结构来进行询问。其肯定回答为“Yes, 主语+can.”，否定回答为“No, 主语+can’t.”。 【例句】——Can your brother play basketball?你哥哥会打篮球吗？ ——Yes, he can.是的，他会。 3、…can….的用法 【点拨】此句型常用来表示某人具备某种能力。can是情态动词，意思是“能；会”，它有一定的词义但不能独立存在，它必须与动词原形一起构成谓语。 注意：不管主语是第几人称，can后都加动词原形。 【例句】——He can swim. 他能游泳。 ——I can play football. 我能打篮球。 ※单元语法突破专项训练 一、单选题 ( )1．Can you play basketball? _________.
