    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 your 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.

    Nowadays smart phones are becoming more and more popular because they provide people much convenience. But they also have badly effect on people. As is often the case, when people are attending meetings, having meals or waiting for buses, you can always find them addicted to their phones, completely ignored others.

    This is really a common phenomena in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat.
