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.

About the film:Tham khảo:

My favorite movie is cartoon “Tom and Jerry”. Tom is a cat with blue and white color. He keeps the house for a normal family and has a very free life. His job is chasing Jerry day by day. Jerry is a brown house mouse. He usually lives in the deep cave behind the wall. Although they hate each other so much and always find ways to hurt opponent but when Tom or Jerry falls into really dangerous situations, then both become another savior. The film is an endless confrontation between Tom and Jerry, bring plenty of laughter for the audiences. I love this film because when I watch it I feel very glad, feeling like returned to childhood.

About the festival:tham khảo

Tet is the most well-known holiday in Vietnam. It is celebrated all over the country. It mostly goes on for 3 days: 1st, 2nd and 3rd of January - Lunar Calendar.
Before Tet, people who work far away from home go back to join their family for the holiday. People clean up their houses, decorate it with Mai and Dao blossom, as well as other bonsais.

On Tet holiday, people cook feasts with various dishes to show dedication to their ancestors. A dish of 5 different kinds of fruit is also put on the altar as a tradition.

People go to relatives' and friends' places to wish them good luck, prosperity and health. Children are always excited since they will get their "salary" - lucky money in the red envelope on this occasion.

Tet is the oppoturnity for everyone to gather with their family, to rest after a long hard-working year, to refresh and prepare for a brand new year of greatness and happiness.

Bài mẫu talk about the festival

I would like to talk about the Lunar New Year festival, also known as the Tet holiday, which is the occasion expected the most by Vietnamese people every year. The festival usually lasts for around 3-4 days, and it takes place when a new year comes according to the lunar calendar.

– The Lunar New Year festival takes place because it is one of the most well-known traditions of Vietnam. Our people have been celebrating this occasion for thousands of years, and although there has been some recent argument about whether we should stop celebrating this festival, I do not think this activity will come to an end soon, at least not in the short term.

– There are some common things that people do during this festival. Perhaps the most important thing is that people who work and study in big cities would go back to their hometown to celebrate the new year with their families and relatives. The new year festival is one of very few occasions that families can gather together, so it is easy to understand why everyone in Vietnam expects this festival so much. Another thing that we usually do is that we give children some “lucky money” with the hope that it will bring fortune to those kids. We also have some other activities such as making “chung” cake, visiting temples and pagodas… and so on.

– The new year festival is so important to me and also to all Vietnamese citizens. The reason is because we get more days off from work and study, and therefore we have more time to spend with our families and our loved ones. It is also a great time to think about what we have done in the previous year, and to make plans for the upcoming year.

P/s : Good luck

There are countless things that I love in this world. But the thing I love most is reading book. I started this bobby when i was 8 years old. I often reading books whenever and wherever I can.

I have no intention of of this useful hobby. In future, I want to read and more book.

5. Talk about your favourite sport

I would like to talk about a sport that I particularly enjoy and have been practising for a few years. It is basketball. For me, this is not only a sport or a physical exercise but also an ideal way for me to relieve of stress and to make new friends.

I first knew about basketball when I was a little kid through a video game called NBA 2k8. However, at that time I did not play badminton at all, partly because I was not an active kid who was aware of the critical importance of physical exercises. When I went to high school, a lot of my friends were a big fan of basketball and my high school offered big playgrounds for sports activities, therefore I practised basketball much more often.

I usually play basketball in the weekends and watch NBA on the nights when my favorite team, the Los Angeles Lakers play. I often go to sports centres with a number of my classmates for basketball matches. Sometimes we even participate in local league, didn’t accomplish anything big but it was extremely fun.

For me, basketball is a good way to help me pursue a healthy lifestyle. It is also an affordable type of sport as you do not have to buy a lot of specialised sports materials. Finally, playing basketball enables me to develop a number of important and non-academic skills such as discipline, team-work, problem-solving and co-operation.

Nowadays almost everyone in the world has contacted with computers. A great part of them has been using the international conputer's net known as Internet. Nobody can deny the important of the Internet to our daily life. However, the Internet has its own advantages and disadvantages.

On one hand, Internet is a big global store of information. You can find many kinds of information which is available on the Internet by some popular searching engines, such as: google.com, yahoo.com,etc. It helps us to communicate with other people around the world easier. The lastest news is always updated on the Internet,too. And it is also a means of education. We can learn foreign language, look up information or take online courses. It is almost an unlimited source of education materials for you to get.

But on other hand. Internet is harmful to our health: Some people spend too much time searching and playing on the Internet which is not good for our brains and eyes. It is not only time- consuming but also destroy relationship because it interferes with family life and communication. And the viruses can spread rapidly and infiltrate systems; destroy data, software of computer. They can attack to your privacy and get some information about you.

In a word, besides learning and entertaining on some websites on the Internet, we also need to limit the time and content that can be accessed to create a secure virtual enviroment.

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

Living in the countryside has a lot of advantages, but also many disadvantages. As the advantage we can consider the fact that the country is less polluted and the traffic isn't so heavy. You are fit and you don't need to worry about your health condition, because in the countryside the air and water are so clean. In the country there are many plant species. There aren't any huge blocks of flats, modern skyscrapers or bothersome traffic jams. In the country you are free to admire the breathtaking landscapes such as huge meadows, peaceful hills or forests. You can enjoy walking in the forest and picking mushrooms or hunting. Another advantage is that you may easily build a big house and the garden, because charges for ground are much lower than in the suburbs. Moreover, living in the countryside is cheaper than it is in the city, so you probably may afford many other things, because the prices are lower. What is more, you can invite your friends to the barbecue organized in your garden. It would be great! The other positive side is the safety. In the rural area the crime rate is much lower. There aren't a lot of housebreaks and the possibility of burglary is also lower. In the countryside people usually and keep eyes on neighbour's estates. They always react when something strange is happening. Country life is very peaceful and silent. You will enjoy the feeling of peace.

However, there are a lot of positive aspects of living in the country side, there are also some disadvantages. Living in the country is slower. People don't need to hurry and have a lot of time. People in the country don't have to work so many hours as they do in the city. On the other hand, they don't earn so much money. Moreover, there aren't such interesting things to do during free time. The unemployment rate is also much higher than in the city. The problem may be also the communication. If you don't have your own car, you may have problem how to commute to work. The same problem concerns the access to the hospitals, schools, police stations and shops, which are usually located far from the village. Last of all, there are some dangers connected with country life such as heavy snowfall or rainfall.

To sum up, I think that living in the country may have a lot of advantages such as fresh air, breathtaking landscapes and comfort, but a lot of people decide to stay in the city, due to the fact that the life in the town is easier. The easy access to shops and other institutions is the great advantage.
