在什么情况下 动词变为ing?
同意楼上的归纳"1。某些词语的固定用法。如：enjoy,finish,feel like,practise,mind,allow等，这些词后面要用动词的ing形式。 enjoy playing football 2。现在进行时态，过去进行时 He is sleeping。
She was watching TV at five yesterday。 3。介词后 I will go to bed after finishing my homework 4。做定语 a swimming pool(a pool for swimming) 5做状语 He is sitting on the chair ,reading a newspaper " 还补充一点:6。
做主语时,在动词之后加ing,变为动名词。 Reading novels is her favorite habit。 。
现在进行里 一些动词后和介词后面
be+v-ing 表示进行时 还有enjoy,finish,feel like,practise,mind后加v-ing be+v-ing 动词为转移性动词如come go arrive stay start leave等 这时表将来时 介词后要用v-ing
1、遇到现在进行时和过去进行时，动词要变成ing形式。 I am writing,please don't talk to me. She was watching TV at five yesterday. 2、放在某些介词后面作介词宾语时，动词要变成ing形式。 He is good at playing football. 3、某些词语的固定用法。如：enjoy,finish,feel like,practise,mind等，这些词后面要用动词的ing形式。 Do you mind opening the windows.
