【题目】 Fighting an enemy that we cannot see is terrible. The novel coronavirus(新型冠状病毒) is one of these invisible(看不见的) enemies and it brings us a great disasters. It has infected(感染) 435,519 people in China and other places in the world as of(截至) March 25. It was reported that it killed 3,281 people in China.

But even if we cannot see the virus, we know how it behaves and spreads around. It is just like most other viruses. To prevent any respiratory(呼吸系统)illness, what we can do is to have good personal hygiene(卫生). And that includes wearing a mask and washing hands. By wearing a mask, we keep ourselves away from the droplets (飞沫)that infected people coughed and (打喷嚏). These droplets can spread the virus — as far as two meters! But these droplets don’t stay in the air for long. They quickly fall and land on surfaces, like tables or clothes. They can also be passed on to elevator buttons(电梯按钮)and door knobs(把手)by our hands. The novel coronavirus can stay alive for quite a long time on smooth surfaces, so washing hands becomes important.

A new discovery about the virus makes it even more necessary to keep these hygienic habits even if we don’t think we’ve interacted(接触) with anyone infected. According to People’s Daily , there is evidence that the virus might be contagious(有传染性的) even before patients start showing symptoms(症状). And these people don’t even know that they’re ill yet.

"However, this epidemic(传染病) brings us a positive(积极的) change. It’s that we’ve developed better hygienic habits. After all, washing our hands is really what we should do every day.

【题目】 Have you ever heard of “a ball of energy”? People often use it to describe very active children. But today we tell about an invention called the socket, that is a real soccer ball of energy. Julia Silverman explains that in fact the socket is a portable generator.

Julia Silverman and Jessica Matthews developed the socket as part of a group project for an engineering class at Harvard University. There are mechanisms in a socket. When you kick, hit or throw it, energy is then kept in it by these mechanisms instead of disappearing into the environment.

Then the user can put something directly into the ball, like a lamp, or a mobile phone charger so that they can get energy from it. For every fifteen minutes of the game play, the socket can provide enough electricity for an LED lamp for three hours, and the ball can store up to 24 hours’ electricity.

The International Energy Association reported last year that nearly one and a half billion people in the world had no electricity to use, and most of them live in sub-Saharan Africa and in India and other countries in Asia.

Julia Silverman and Jessica Matthews both had experiences in developing countries before they began the project. They knew that power shortages are a serious problem in really areas. There’s an energy crisis in the world. One out of every five people in the world don't have any electricity, there are a lot of health problems because what people use instead of any electricity are harmful choices like kerosene lamps, which produce a lot of smoke.

Julia Silverman says the socket ball is one small solution to a big problem. Jessica Matthews and Julia Silverman hope their socket ball will shine more light on the problem of power shortages. It offers people a chance to put their energy into the world’s most popular sport and get some energy in return.
