He ( ) ( read ) that book before.这个括号应该填什么?
has read
一见before即思过去完成时,例句:I've been there before
其他神马都是浮云~~~~
read的过去分词形式还是read 不过注意读音不同哦~~~哈哈

因为有个before(在……之前),所以这句话要用过去式,read的过去式是原型。所以填read

He (was read ) ( read ) that book before

He ( was reading) ( read ) that book before.

He didn't read that book before.

是不是过去完成时啊?

was read
