He is running. 看！他在跑步。 例句：Look! She is winning. 看！她赢了。 易错提醒：be动词必须与主语一致：I用am，he/she/it用is，you/we/they用are。He is running（✓）不是 He am running（✗）。be动词不能漏掉：She playing（✗）→ She is playing（✓） ✎ 大显身手 一、单项选择题 ( )1. She _______ playing ping-pong. A. am B. is C. are D. be ( )2. I _______ running in the sports ground. A. am B. is C. are D. be ( )3. He is _______ very high.

She is _______ (play) ping-pong. 2. He is _______ (take) photos. 3. They are _______ (run) in the sports ground. 4. The children are _______ (jump) very high. 5. We are _______ (read) a poem. 考点 03 V-ing的构成规则 “She is playing ping-pong.” 她在打乒乓球。（play → playing） “He is taking photos.” 他在拍照。（take → taking） ▸ 动词变V-ing有三条规则。 解析： 一、一般动词：直接加-ing play → playing read → reading jump → jumping 例句：She is playing ping-pong. 她在打乒乓球。 例句：He is jumping very high. 他跳得非常高。 二、以不发音e结尾：去e加-ing take → taking make → making 例句：Lots of people are taking photos. 很多人正在拍照。 三、重读闭音节结尾：双写末尾字母加-ing run → running swim → swimming 例句：Wei Mingyu is running. 魏明宇正在跑步。 易错提醒：take变taking不是takeing（✗），要去e再加ing。run变running不是runing（✗），要双写n再加ing。jump变jumping不是jumpping（✗），jump末尾不重读，直接加ing。 ✎ 大显身手 一、单项选择题 ( )1.
