The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus and Neptune (Pluto is now classified as a dwarf planet).

Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space.

The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun and escaping into space, they spend eternity orbiting around their parent star.

The Planets orbit in the same direction (counter-clockwise looking down from above the Sun’s North Pole); all but Venus, Uranus and Pluto also rotate in that same sense. Mercury has the fastest elliptical orbit,

48 km per second. It has the shortest revolution at 88 days. Pluto has an orbital speed of 5 km per second. It takes 248 years for Pluto to make one complete revolution.

Write a paragraph talk about disadvantages of living in the countryside - thanh hằng

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 are the great advantage.

Tet Holiday is the biggest annual celebration of Vietnam in the first days of lunar New Year. During these days, people welcome a new coming year with good health, lucks and success. Tet holiday is very special for Vietnamese families to reunite and celebrate together.

The preparation for Tet holiday is taken place very soon because it requires many steps. All members of families clean and redecorate their houses together. Then, they buy food, drink such as cookies, sweets, candied fruit, melon seeds...to offer their guests and to store because in this occasion, many shops are closed. A branch of peach flower or a kumquat tree cannot be absent from every home during these special days. Children are the most eager, as their parents will buy them new clothes. In addition to buying things, many Vietnamese families make Chung cake, pickled onion, frozen meat, which are our country's traditional food on Tet holiday. We decorate ancestral altars with a five-fruit tray, vegetables, sweets, and flowers.

In the last day of the previous year, people become more excited as they feel that the New Year is very near to them. Everybody all waits for the sacred moment when the clock points 0 am and fireworks light up everywhere to wish for health, lucks and happiness in the next year. Streets are extremely crowded. On contrary, in the first morning of the year, everything seems peaceful and quiet as people want to sleep longer to enjoy the moment with their cozy family. However, there are some families getting up early to come back to their hometown to visit their ancestors' graves and relatives. From noon on, everybody go to their neighbors' houses to wish them a happy new year. Children in new clothes are very excited, as they will get lucky money from adults.

There are many activities to welcome new coming spring in this occasion. Children usually take up pens to write their first essay, hoping for good results in school. In spring festivals, everyone especially the young takes part in the traditional games such as rollercoaster, tug of war, cooking rice, cock fighting etc. to express their happiness while farmers wish for bumper crops. Women often go to pagodas to show Buddha their hearts and wish their families good things and power to avoid bad lucks. During the first days of New Year, Vietnamese people do things that are supposed to be good for themselves and their loved ones such as wearing red clothes, buying salt, taking chance or praying... and avoid saying taboos(related to death, breaking...). Each region in Vietnam has it own customs to celebrate Tet, which are very special and unique.

"Tet" is the word that is very familiar to Vietnamese people whenever we think about our country. This is the time for family reunion, for festivals, and for people to give love to their loved one. As for me, I enjoy the warm and cozy Tet's atmosphere when all members of my family stay and talk together.

Last weekend, while cleaning my bedroom, I came across an album and found a photo of me on the first day coming to school – a day filled with special emotions. It was a sunny day with many white clouds. My mom was the person that accompanied me to school. On the way to school, i could see many other children around my age are going to school like me, some of them were crying a lot. Fifteen minutes later, we arrived at the school. Mom said goodbye to me and suddenly i bursted into tears.I felt lonely and scared because there was no one beside me then. Then a woman came by my side. She had a bright smile and a gentle face which reminded me of my mom. With a warm voice, she introduced to me that she was my teacher. I had thought that teacher was someone that would punish me when I made mistakes, but my first impression was a little different from my expectation, she was like a sweet angel. Later, she took me to my new class.There are a lot of new friends. Sitting at my place, looking around the classroom, I was impressed by the colourful and lovely space here. It was painted in bright colours with a large book shelf at the corner, filled with comics and toys, which were all well-organised. After that, the very first lesson at school got started. Beside learning to spell and write, I was also taught to sing, to draw pictures and was told a lot of interesting stories, which made me really excited. It was my first day studying at school, quite a long time ago but still gives me a sense of nostalgia for my carefree childhood.
