在英语中,"think" 后面通常不直接跟 "ing" 形式,因为 "think" 是一个及物动词,需要接宾语。例如:
I think he is busy.
She thinks the book is interesting.
但是,如果你想要表达“思考”某事或某物,可以使用 "thinking" 形式,这时 "thinking" 通常作为名词或形容词使用:
I am thinking about my next trip.
That sounds like a good idea, let's think about it.
"think" 后面是否加 "ing" 取决于你想要表达的意思和语法结构。
