Question

2.He forgot his book in the classroom after class.
3.It spends us a long time to finish the exercises.
麻烦还说一下为什么

Answer 1

1 His handwriting is better than mine.
原因：he是人称代词，与handwriting搭配必须是物主代词，故改为his。同理，I不能与his handwriting相比较，应该是表示“我的”即mine。
2He forgot to take his book in the classroom after class.
下课后他忘了把他的书带出教室。
3It costs us a long time to finish the exercises.
it作主语的话，应该是花了我们的时间，故用cost。spend表示某人或某事主动花时间去干什么。
