Should all colleges and universities require their students to spend at least one semester studing abroad? The author considers that studying abroad could make students more mature and more independent, which is good to their development. Indeed, students who study in a forgeign contry are more mature than other people who is at the same age;however, studying abroad could also cause many troubles, which would have permanent inflience to students.
Students study in colleges and universities not only major class, but also the ability of learning and independence. Studying in a forgein country could prompt the development of independence and learing ability, as well as well lerned forgeigh languiage. In a forgein country, students have no parents and no friends to depend, thus, they have to wash clothes and cook food on their own,which could practice their the ability of independence. What's more, studying abroad could also practice students' ability of learning, for they have to learn languige very well; otherwise they would not follow teachers. Besides, students would improve the ability of timing orderly, since they have many things to do. For example, study, rent, party, and work. If they couldn't arrange everything sequencely, they wouldn't study well and live confortable.
Granted that the advantage of studing abroad is surperior, the threaten could also exist. Students who study in a forgein country might encoumber some dengerous things, such as enter some dangerous places, or the phenomenon that they come accross theft, but no one help them.  Plus, some of students might be so excited to a new palce that they are rife with curious; consequentely, students hang out all day long but study. Moreover, since they are poorly of their English, students faild to friend with forgein people, which might cause students developed some mental diseases. In spite of these, students whose family could support them enough mongey to go abroad might depresssed, because their fridens all go abroad.
I think one semester will not suitable to everyone, for student have differnet destination. For some students, they go abroad in oreder to futher study, such as PHD, or futher research, thus one semester is far from enough. In my opinion, at least five years are suit to them. As for some students just to take part in a compition, they might just need ten days. To students whose major is human culture, I think, they might need several years to study deeply to a forgein culture.
To put it in a nutshell, even though not all students are suitable to study in a forgein country, I suggest, students shoud spend severl periode of time to study abroad, for improving their all aspect of ability. As for the time, students should base on their destination to decide.
