解答
换成一般时态 就是“It's a favorite magazine”
由此可见 本句的动词是is,现在完成时就是have done在这里就变成了have been
推荐
- has been doing与had been doing,这两个时态分别代表怎样的概念,表示怎样的动作发生,用于何种情况,请大家分别具体解释一下它们所用的场合
- i has been doing 还是i have been doing
- has been doing还是 has done
- has been doing have been done区别
- has been doing 表示从过去一直到现在,那么它的被动态是什么呢
