    When you are in a group with good classmates, it can be very good for you. You should always be prepared when going to school, but there are days when you forget a pencil or a notebook. You can then borrow one from your classmate. If you're having trouble understanding a certain question, classmates can be quite helpful. Having a difficult math problem explained to you by a fellow student will be much easier than asking your teacher, because your teacher can't be always with you. Some teachers will not tell you homework if you've missed a class. Having a classmate who will let you review his note can help you a lot in a situation like this. If you happen to have a classmate who lives nearby, you might be able to carpool (拼车) to and from school. Not only will this save some money, but also it will help protect the environment as well. Students who enjoy their surroundings and get along well with their fellow classmates are usually much happier than those who are not.
