主语+Be动词和主语+动词的区别
主语+Be动词和主语+动词这两种用法怎么区分呢?比如说He was thinking about a maths problem.和 He thought about a maths problem.
是这样啊 那比如现在时(同样时态的)主语+Be动词和主语+动词这两种的句型的话怎么区分用呢?我每次都分不清楚。
答
我先回答你的比如那里,He was thinking about a maths problem 这个句子是他一直在想一条数学问题,而下面的那个是过去式,所以用thought.(think的过去式是thought)就可以说,I'm think about a maths problem.
