    After a long day at work, coming home is a breath of fresh air. 1. However, is it as healthy as it can be? Below are a number of things we can do to create a healthy home environment that will help to case the workday stress and promote our physical and mental health.

Cleaning the house regularly is the first thing we should do. It may seem like a tiring thing to clean but there is a reason for doing so. We can remove dust by cleaning the house. Leaving layers of dust everywhere means that there is a build-up of dust. 2. Into our lungs.

Making sure the rooms are full of sunlight is also important. We may not realize it but sunlight is an important part of our growth. We all know that sunlight promotes better working conditions. 3. Think about using a Parans system where sunlight does not reach. This technology gathers the sunlight by using solar panels (板). It can send out sunlight wherever we are.

4. Going green will help to remove toxins (毒素) in the air. They also give off oxygen, which can lower stress and improve our moods.

Along the lines of being green, it can also be vital to think about what things we are bringing into the house. Try to avoid specific plastics that are harmful to health. 5. They may contain poisonous chemicals that can be breathed in, or simply absorbed through the skin.

A.And where do these layers of dust go?

    The 2016 Rio Olympic Games have come to an end. Without doubt, many Chinese sports fans sat in front of the TV and cheered our athletes on, hoping that they would get as many gold medals as possible.

But sometimes our desire for gold medals can result in the sadness of failure. When Liu Xiang, China’s track hero, pulled out of the Beijing Olympics due to injury, he greatly disappointed many Chinese sports fans.

But things are different now. In the 2016 Rio Olympic Games, we saw a healthier Chinese attitude towards the sports people, fully in line with the Olympic spirit.

China didn’t win any gold medals on the first day. But, instead of criticizing(批评) the athletes who failed to win, most of the fans were happy with their efforts. “Looking at the results in the right way when an athlete misses out on gold shows the maturity(成熟) of a person, and is also a challenge for a country to face up to in the process of development,” commented CRI.

Swimmer Fu Yuanhui won fans’ hearts, even if she only won the third place in the 100m backstroke final. Her fans on her Sina Weibo have increased 100,000 to over 6 million. Many sports fans appreciated her straightforward character and attitude towards competitions.

“The warm support from Internet users shows that public attitude towards competitive sports and the Olympics has gotten to a higher level”, said an article in the People’s Daily.

1.What can we know from Paragraph 2?

A.Gold medals can also cause sadness.

B.Liu Xiang always disappoints his fans.

C.Fans have high expectations of Liu Xiang.

D.Liu Xiang got injured before the Olympics.

2.What is people’s attitude now towards the athletes who failed?

A.Interested. B.Understanding.

C.Angry. D.Disappointed.

3.What makes people like Fu Yuanhui?

A.Her Sina Weibo. B.Her kindness to the fans.

C.Her attitude to competitions. D.Her winning a gold medal.

4.What does the author mainly want to tell us in this passage?

A.Winning gold medals is important.

B.Changing attitude to athletes is a must.

C.Results are not important in the competition.

D.Peoples’ attitude towards competitive sports is healthier.

    Scientists blame greenhouse gases for being a major cause of climate change around the world. This is because greenhouse gases trap heat in the atmosphere and make the planet warmer.

Now, a team of researchers has announced a successful experiment that turned carbon dioxide into useful liquid fuel. The researchers created a device, called a reactor, which changes bon dioxide into a pure form of formic acid(甲酸). Formic acid is a substance (物质) found in ants and some other insects, as well as in many plants. It is used as an antibacterial material and in the processing of some kinds of clothing.

Haotian Wang led the research team. He said in a statement that the results of the experiment were important because formic acid is a major carrier of energy. So, the substance can provide a way to reuse carbon dioxide and prevent it from being released into the atmosphere. “It’s a fuel-cell fuel that can generate electricity and send out carbon dioxide which you can grab and recycle again,” Wang said.

“Other methods for turning carbon dioxide into formic acid require intense purification processes,” Wang said. Such methods are very costly and require a lot of energy. The Rice University team said it was able to reduce the number of steps in the traditional process to create a low-cost, energy-saving method.

The researchers reported the reactor device performed with a conversion rate (转化率) of 42 percent. This means that nearly half of the electrical energy can be stored in formic acid as liquid fuel. The team said the reactor was able to create formic acid continuously for 100 hours with little degradation (退化) of the device’s parts.

Wang said the reactor could easily be used to produce other high-value products, including alcohol-based fuels. The researchers noted that the technology could also be a big help in solving another major energy problem—how to store large amounts of power in small places.

A.Greenhouse gases. B.Chemistry waste.

C.Formic acid. D.Liquid fuel.

2.What do we know about formic acid?

A.It is a large amount of power. B.It can be found in ants.

C.It is high- value equipment. D.It is a substance in clothing.

3.What is Wang’s attitude towards his own research?

A.Doubtful. B.Aggressive.

C.Optimistic. D.Uncaring.

4.In what magazine can you read this text?

A.A travel magazine. B.A sports magazine.

    Australia and New Zealand’s health organizations have given their advice on when to use sunscreen (防晒霜), suggesting Australians apply it every day to avoid bad health effects.

A Sunscreen Summit took place in the Australian State of Queensland. During the summit, representatives from some of Australia’s leading research, medical and public health organizations examined the evidence on sunscreen use and determined that in most parts of the country it is beneficial to apply sunscreen every day.

“Up until now, public health organizations have recommended applying sunscreen ahead of planned outdoor activities but haven t recommended applying it every day as part of a morning routine (惯例),” professor Rachel Neale from QIMR Berghofer Medical Research Institute said. “In recent years, it has become clear that the DNA damage causes skin cancer and melanoma(黑色素瘤), which is caused by repeated small exposure to sunlight over a period of time,” Neale said. “In Australia, we get a lot of sun exposure from everyday activities such as alking to the bus stop or train station,” Neale said.

A study showed that one in two Australians believed it was unhealthy and potentially dangerous to use sunscreen every day. However, Terry Slevin from the Public Health Association of Australia says it is wrong. “There is consistent and compelling evidence that sunscreens are safe,” Slevin said. “Importantly, medical trials have found that people who use sunscreen daily have the same levels of vitamin d as those who don’t,” Slevin added.

Australia has one of the highest rates of skin cancer in the world which is made worse by the country’s close to Antarctica where there is a hole in the ozone layer (臭氧层), letting in higher numbers of UV rays.

1.What made Australian health organizations advise Australians to use sunscreen?

A.The makers of sunscreen.

B.Australian government.

C.The Sunscreen Summit.

D.New Zealand’s researchers.

2.What is not recommended before the Sunscreen Summit?

A.Using sunscreen before outdoor activities.

B.Using sunscreen as a morning routine.

C.Reducing the use of sunscreen.

D.Reducing outdoor activities.

3.What is the misunderstanding of many Australians?

A.People using sunscreen won’t have skin cancer.

B.Sunscreen will never take effect.

C.People using sunscreen have the same levels of vitamin

D.D. Sunscreen is bad for people’s health.

4.Which of the following best explains “compelling” underlined in paragraph 4?

A.Interesting. B.Disappointing.
