The Covid-19 epidemic is affecting many countries around the world, including Vietnam. So what should we do to prevent this corona virus disease? The first is that this disease is transmitted through the respiratory tract, so wearing a mask is the most important thing and avoiding large gatherings. Secondly, this disease can also be transmitted through objects that an infected person touches, so we need to wash our hands every day. Thirdly, every time we come back from an epidemic area, we must declare our health to know if we are infected with covid. Everyone please follow the 5k message to protect your health and your family to win the pandemic

Good friends study

I think that the best leisure activity for teenagers is playing sports. Firstly, they can find friends who have the same interests. Secondly, physical activities are a good way to relieve stress and reduce depression. Moreover, sports can help develop teamwork and leadership skills that may be very necessary for their future jobs.

Currently, the development of COVID-19 is very complicated, so students are away from school and living at home to prevent infection. We often spend a lot of time together during the school year, so it is imperative that wash your hands often, especially before eating, after blowing your nose, and after using the toilet. And more importantly, we should wear a mask when recommended by the school and authorities and should be worn properly. We have to make a correct minimum distance of 1.5 m with people. Airborne respiratory viruses exist in saliva droplets when someone sneezes or coughs. So cover your nose and mouth when you sneeze or cough with a tissue or cough and sneeze into your elbow. We love to share utensils, favorite toys and cups with friends, but do not share eating utensils with friends, especially during flu season and other respiratory illnesses. It is important to comply in order to best prevent the Covid-19 epidemic.

Passage?

You all know there are four main skills when we study a foreign language, which are listening, speaking, reading, and writing. So what's the most difficult one for you? I read a survey and it says, listening & reading are the steps for learners to 'collect' information, and speaking & writing are the steps to 'produce' the information that you've collected from listening & reading. Thus, speaking & writing are more difficult than listening & reading. And according to that survey, writing is the most difficult one among the four skills.

Certainly each learner will find out which skills they are good at or bad at because the ability of each learner in each skill is different. For example, some learners can listen very well while most others think that's the hardest skill.

And I think each language has its own most difficult skill too. For most Chinese learners, say, writing is always hard because its alphabet is pictographic. And for most English leaners, listening seems to be the hardest one.

As for me, reading is the most difficult one. It's so hard to understand everything written by a native writer.

Protecting the environment includes the indoor environment and indoor air quality. One way to protect the indoor environment is not to bring indoors any products with surfactants in them. This means switching to safe, non-surfactant cleaners and laundry products. Another way of protecting the indoor environment is not to bring in grooming products that contain phthalates or other volatile organic chemicals or persistent organic particles in them. This means switching to safe, phthalate-free and VOC/POP-free grooming products. This also means switching from manufactured "perfume" fragrances to natural essential oil fragrances, the original perfume material.

Another way is not to bring in bleached recycled paper or plastic products. This includes most food packaging boxes, even organic ones (except for those that have switched to non-bleach/chlorine recycling process products), most meat and poultry trays and plastic wraps, most egg cartons, most ice cream cartons, most recycled school loose-leaf and notebook paper, most plastic bags. Another way is not to walk into the house with your shoes on. The EPA has determined that more than 50 percent of indoor air toxicity comes from petrochemical particulates tracked onto carpets from shoes (worsened when shoe soles are constructed from petrochemical based materials).

Draconian, drastic measures are needed to protect both the outdoor environment and the indoor environment. If our mega-scale free market system worked, we could demand unsafe materials be taken out of production and easily improve indoor air environments, but it doesn't, and we take what we are given while advertising campaigns convince us that what is given is great and the best and that which is what to covet.

It’s a common sense that fossil fuels and non-renewable sources play a vital role in our daily life. They include oil, coal, natural gases, which produce energy and can be seen in every part of life. However, people are using it too much and they are running out, which may make a severe energy crisis around the world. Pollutants released during burning fossil fuels cause air pollution, which affect people’s health and humans’ life. To prevent this from happening, there are some following suggestions. First and for most, reduce the amount of fossil fuels for energy by walking, cycling and using public transport instead of cars or motorbikes. Besides, don’t waste energy, turn off lights before going out or switch off appliances when you don’t use them. Secondly, scientists and government should do research and expand the use of renewable sources such as wind power, solar energy or wave energy, etc. These powers are not only sustainable but green and not produce waste. Finally, awareness should be raised among citizens, especially in education and neighborhood. In conclusion, If people join hands to do big things, we can save the earth from destruction.
