         Countryside life has some problems due to late improvement including health, technology and transportation. Those are some serious problems in the countryside; therefore, we may need to improve those places or agree to live there. To conclude, I think life in the countryside is better than in the city, but health care and improvement is developing slowly; Therefore, we must pay attention to those problems and how to solve them effectively. And there are fewer places to entertain. One has to travel further to get to the cinema or shopping mall. Second, because there are fewer shops and services, there are fewer job opportunities. A person will have to travel a longer distance to get to his or her place of work and this can be expensive. In short, this country is more suitable for some people than others. If I had to choose, I would live in the country

I think the Internet is a very fast and convenient way for our to get information. It is very useful because it help us for many purpose, exam:education, communication,entertainment and commerce,...
Nowaday, people use more the Internet because the Internet as a
source of information such as news, articles, weather forecast,... and
as a means of education as online lesson, online school, self study,...
and as a source of entertainment such as music, movies, game,...It helps
people can do online commerce, we can communicate with friends and
relatives by means of e-mail or chatting. However, next to the benefits,
the Internet is still many limit such as: can not easily get access to it,
onlytime coming and costly but also dangerous because of virus and bad
program, Internet user sometimes have to suffer various richs such as spam
or electronic junk mail, and personal information leaking.

In my opinion, the Internet has three major drawbacks. Firstly, when you surf the Internet, your personal information, such as name, address and account can be accessed by hackers. For instance, if you use credit cards to shop online, your card information can be stolen, and then money in your account may be used up. Secondly, pornography is another serious issue, especially for teenage users. Due to the easy access to pornographic websites, teenagers may be incited to act out sexually. According to Dr. Jennings Bryant, 31 percent of male and 18 percent of female high school students admitted imitating some acts in pornography. Lastly, computers with Internet connection are likely to be infected with viruses which disrupt their normal function. It is hard to prevent virus infection although we use anti-virus programs. To sum up, information leakage, negative influences of pornography on teenagers and virus threat are three main disadvantages of using the Internet.

Computer plays an important role in this information era. However, while bringing certain advantages, this high-tech device has its own limitations.
Internet is an indispensable part of life in this high technology era, it has its own limitations. The troubles, however, do not stem from computer or the Internet themselves but the users. The new technology is entirely positive but the users take its advantage for negative purposes. Some people use computers to do nothing but play games, chitchat, spam, create dirty information on the Net. They directly or indirectly detract Internet from its benefits to the community. Many people are scared of using Internet because of their fear of being abused, or spamed. or becoming Internet addicts. In addition, sitting in front of the screen for long hours can lead to obesity, backache, and short-sightedness. Besides, people paying too much attention to online activities may become passive, sluggish in real life because of their lacks of communication, and manual labor.
In short, everything has its two sides, so does computer and Internet. Therefore, it is necessary that we use it for right purposes.

The Internet plays an important role in our modern life. However, every coin has two sides and we can find out pros and cons of the internet by my following provement.

The Internet is a breakthrough in developing technology. It brings us wonderful advantages. First, education is more and more improved due to appearance of the internet. Students can learn and look for basic knowledge online without spending too much time in the libarary. This leads to the fact that it is very convenient for both teachers and students to broaden their perception. Second, the internet shorten the distance of people even though they are very far from each other. Skype or Yahoo are good ways for them to contact and have fun. It is true to say that distance is not a big problem in such a developing technology world. Third, the internet makes everything easier and faster. For example, we can send or receive documentary through email for a short time wwhile 10 years ago, we need to wait foe 3 or 4 days to send to a far distence.

On the other hand, the internet also has drawbacks. People especially teenager are easily involved in computer games. They take so much time to sit in front of the screen to play games. This doesn't only affect to their health but it also decrease the amount of money which their parents earn by hard works. They can't understand that money doesn't grow on tree. Moreover, the internet prevents them from taking part in outdoor activities beacause of the internet's attraction. This will slowdown socal skills and cause their inconfidence .

In a word, the inetrnet is one of the most wonderful inventions in the world. However, it also causes trobles in our life. Thus, we should use it in moderate

The world is developing day by day, and one of its biggest invention is the Internet. The first adventage of the Internet is that it changed our life style. While in the past, people had to go to the supermarket to buy what they wanted or they had to visit the park for entertainment, now we only need to stay at home with a phone connected to Internet, we can easily buy anything or can relax with video games. However, it is also a disadvantage. Some people spend too much time on it, this can do harm to our health and our eyes. Therefore, although the Internet is usefor for us but we should spend little time surfing it.

Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency

Năng lượng mặt trời thu được bởi các tấm pin mặt trời là một dạng năng lượng vô hạn, vì trái đất bị bắn phá với lượng năng lượng mặt trời cực lớn mỗi ngày, theo Phòng thí nghiệm năng lượng tái tạo quốc gia. Nó cũng sạch sẽ, không tạo ra khí cacbonic và bảo dưỡng rất thấp, vì các tấm pin mặt trời không có bộ phận chuyển động. Thật không may, Phòng thí nghiệm năng lượng tái tạo quốc gia cho biết chi phí lắp đặt cao của nó làm cho nó đắt hơn gấp bốn lần so với chi phí điện từ một công ty tiện ích tiêu chuẩn. Để hoạt động tối ưu và sản xuất năng lượng tối đa, nó đòi hỏi thời tiết nắng quanh năm và rất tốn kém nếu sửa chữa là cần thiết, theo Cơ quan Bảo vệ Môi trường Hoa Kỳ
