   As is known to all, nowadays many students are interested in studying abroad.

Attending schools abroad has many advantages. First, by looking at our own country from outside, we can best see the strong points and weak points of our nation and therefore broaden our minds. Second, while studying in a foreign country, we can travel widely, visiting famous scenic spots and making friends with the local people. Third, we can use the foreign language in our daily life so that our ability in that language may be improved quickly. But the most important is to learn advanced(先进的) science and technology. For all these advantages, it is really worthwhile to go abroad for education.

However, as everything has two sides, there are also some disadvantages in attending a foreign university. The most serious problem is the language barrier(障碍). Most of the students who are ready to go abroad do not prepare themselves well for the new language environment. As a result, on arriving there, they will find it difficult to understand what the instructors are saying in class. Besides, for not knowing about the customs and way of life of the local people, they may run into trouble in dealing with various situations. Therefore, misunderstandings foten arise. Furthermore, the cost of living is much higher than that in our country, so most students have to find part-time jobs in order to help support themselves. Faced with these difficulties, many students find themselves unable to pay full attention to their studies and some students may even fail in their courses and learn little.

Therefore, given an opportunity to attend a school abroad, one must consider the factors carefully before making up his mind. On the one hand, it is a good thing to go and study abroad. But on the other hand, one must not neglect(忽视) the disadvantages.

Yours,

   Cellphones, tablets, and computers are keeping children and teenagers awake at night-even when they' re not in use, according to new research. A study published on Monday in JAMA Pediatrics says that media devices are causing kids to sleep less and reducing the quality of sleep that they get. This leads to trouble of staying awake the next day.

Researchers analyzed hundreds of studies of children and teens aged 6-19. The scientists found a strong and consistent association between the use of technology at bedtime and poor sleeping. The reason is not just that kids are staying up too late with their devices. Using a computer can overstimulate the mind and emotions, the researchers say. A smartphone or tablet also gives off a light that affects the body's natural timing. These factors contribute to poor quality sleep. And many kids could be at risk. According to the study,72% of all children and 89% of adolescents have at least one device in their sleep environment. Most of these devices are used near bedtime.

"The harmful association between screen-based devices and kids' sleep is a major public health concern," the study concludes. In their conclusion, the researchers urge parents to understand the damaging influence of device use before sleep.
