She is going to read a book. be going to 否定句用法 否定形式直接在be动词后加not，构成否定结构 结构为主语+am/is/are+not+going to+动词原形 am not无缩写形式，is not缩写为isn’t，are not缩写为aren’t 用法示例：I am not going to swim. They aren’t going to stay at home. be going to 一般疑问句用法 将be动词直接提至句首，即可构成一般疑问句 结构为Am/Is/Are+主语+going to+动词原形？ 句末用问号，回答时需用Yes/No+主语+对应be动词 用法示例：Are you going to see a film?

The flower looks beautiful. 形容词 常见分类及词汇 外观类：beautiful, tall, short, blue, white, small 性质类：old, new, long, short, clean, dirty 感受类：quiet, happy, sad, interesting, boring, exciting 状态类：tired, hungry, thirsty, busy, free 形容词 易混点提醒 形容词不能修饰动词，修饰动词需用副词 形容词无单复数变化，不可在词尾加-s/-es 系动词后只能接形容词，不能接副词 错误示例：He runs quick. 正确示例：He runs quickly. 语法小练 单项选择 1.I ______ going to visit my grandma this weekend.
