However, officials at the Centers for Disease Control and Prevention (CDCC) in the United States stated that they "did not have any evidence". about the patient's infection before the onset of symptoms .A research team estimated that the virus's basic reproduction coefficient (also known as the basal infection coefficient, R_ {0}) ranges from 5 to 10, this means that one person infected with the virus can infect 5 to 10 others. Other research groups have estimated that the basic reproductive index could be from 2 to 4.5.Symptoms reported include fever in 90% of cases, fatigue and dry cough in 80% of cases,  20% suffer from shortness of breath and respiratory failure accounts for 15% .Blood tests often show a low white blood cell count.Good self-protection includes: maintaining good hand hygiene and breathing (do not touch the eyes, nose, mouth) persevere safe eating habits, do our best to avoid contact be intimate with anyone who has a respiratory illness (such as coughing and sneezing). There is currently no specific cure for the new type of Corona virus.

Enviroment is neccessary thing for this life. Enviroment is the air we breath, the water people drink and is everything they need for their life. But now the most important thing for the life is being polluted. This pollution affects the health of all living things. Air is damaged by lorry fumes and car, and power stations create acid rain which can destroys entire lakes and forests. When fossil fuels: gas, oil and coal are burned to provide energy for cooking, lighting etc. they form polluting gases. Not only on land but also in the sea, oils spills pollute sea water and kill marine life; chemical waste from sewage works and factories, and artificial fertilisers from farmland, pollute river water, spreading disease, and killing wildlife. Everything is being caused by human’s existence. Humans create rubbish! Each household produces about one tonne of rubbish each year! Most of this is taken away by dustmen and burned in incinerators or buried in enormous landfill sites – both of these actions can be dangerous for our environment.

But only people can change and solve it. Pollution could be prevented by all thing we do each day. First people can use recycled paper to save trees. Second try to avoid using plas. It is hard to recycle. People should refuse to use carrier bags. If people can not avoid buying plas bags, they should use re-use plas bags many times. Finally people must take their old clothes to charity shops. People also should save energy to protect environment. Switching off all electric things when they are not in use, walk or use a bicycle instead of car for short trips, keep healthy life and  keep clean atmosphere.

Keep clean environment isn’t only all ways are mentioned before but also to protect natural resources. That is the way to conserver wild life. First we need to conserve the old forest, rainforest, build more safari and national park, and plant more trees to make place to live for wild animals. Second we need to prohibit hunters who hunt animals too many out of the law allowance.

Finally, we now know that enviroment is the most important thing for life and we know how to protect and use it scientifically. Everyday we invent and find more and more way to protect enviroment. I hope that in the future the earth will be cleaner.

My dream house is not necessarily a large house, as long as it fits my style and character. It is located on the outskirts of town. It will be a two- storey house facing west-south side. Moreover, my house can not be lack of a large garden surrounded by thousands of different colors of flowers and fruits. I like it the most when having a breakfast or enjoying night views in my own garden. Simplicity is beauty, this explains why I would prefer an airy space rather than a well-equipped house. However, the house should have basic necessities in the kitchen and bathroom to serve all my demands in daily life. In addition, I will use bright color tones for the whole house, especially my bedroom to make it more spacious. My bedroom will be more perfect and ideal if it has a balcony where i could smell the fragrance from the garden as well as enjoy the sound of the birds in the morning. Besides, I also have an intention of having a small garage and storage. In conclusion, I wish I could make my dream become true.

There are some differences between Tet in the North and the South of Vietnam. In the North, the traditional food of Tet is Chung cake - a rectangular sky rice cake with meat, which is wrapped in phrynium. People usually buy the cakes with some cherry blossom branches as a symbol of Tet to decorate their houses. In the South, people consider apricots and Tet cakes are the symbols of Tet.
