定义
谓语动词的构成: ________________。
系动词be + V-ing
This is the structure of a sentence in the present continuous tense.
We form the present continuous tense with the verb to be + (the base form/the -ing form) of the main verb.
We form the –ing form of the main verb like this:
work—
buy —
visit —
working
buying
visiting
take –
have —
write —
②以不发音e结尾的动词，去掉e，加-ing
taking
having
writing
Do you know how to change verbs into V-ing forms
① 一般情况下，动词后直接加-ing
V-ing 的构成规则
stop –
shop –
sit –
③以辅音字母+元音字母+辅音字母的重读闭音节结尾的动词，如果末尾只有一个辅音字母，双写辅音字母，然后加-ing
stopping
shopping
sitting
lie-
die-
④特殊变化(需要特别记忆)
