      The summer holiday is coming. My classmates and I are talking about how to do during the holiday. We can chose between staying at home and take a trip. If we stay at home, it is comfortable but there is no need to spend money. But in that case, we will learn little about world. If we go on a trip abroad, we can broaden you view and gain knowledges we cannot get from books. Some classmates suggest we can go to places of interest nearby. I thought that it is a good idea. It does not cost many, yet we can still learn a lot.
