Why is it called Mars（火星）? Well, Mars is the name of the Roman god of war（罗马战神）. People see the planet（星球）as a symbol of war for thousands of years. It is also known as the Red Planet because of its color. It is red because it’s rich in iron（铁）. Chinese people called it the “fire star” for the same reason.
Scientists was interested in the planet. They first saw Mars in the sky more than 4, 000 years ago. Then, people from all over the world studied the planet. About 200 years ago, scientists started to study pieces of Mars. They broke away and drifted（漂流）through space for millions of years before they got to Earth.
Scientists have learned some things about Mars. For example, Mars is home to a 21-kilometer-tall mountain—the tallest in our solar system（太阳系）. However, Qomolangma, Earth’s highest mountain, is just 9 kilometers tall. Like Earth, Mars has moons. It has two moons named Phobos and Deimos. The Red Planet also has the largest dust storms（沙尘暴）in the solar system. And they can last for months.
Earth is 10 times heavier than Mars. So The Red Planet’s gravity（重力）is only 37 percent as strong as Earth’s, meaning you can jump nearly two times higher on Mars. For the same reason, you are two times heavier on Earth than on Mars.

【推荐1】Space tourism is no longer a thing of science fiction. There are lots of companies planning to send people into space in the next few years. Space X is one of the most famous companies offering trips to space. So far, it has had over 100 customers. And in April, 2022, it sent 4 people into space. Now, what can space tourists do while in space? Here are some examples:
See the Earth from space
Seeing the earth from a distance has always been a dream. It gives most people a sense of both achievement and wonder (which is also why people climb the highest mountain and dive the deepest sea on the Earth).
Stay in space hotel
Hotels are directly connected with tourism, right? So if there’s space tourism, there might also be space hotels up soon. Orion Span has been planning to send tourists to stay in their “space hotel”, which would hold six people at a time.
Eat in space
Eating is not easy in space. Even drinking water is difficult. Oh, a quick fact! You aren’t allowed to burp in space! Bubbles will come out of your mouth and it might be dangerous to leave them around.
Visit the Moon and other planets
Space tourism companies are racing to launch the first tourist flight to the Moon. Although there might be a long way to go before common people can step on the Moon, we will probably see it in our life time. And who knows, maybe we’ll even see hotels on the Moon.

【推荐1】An online survey by ride-hailing company Didi found that more than half of the participants agree to allow teenagers under 18 to ride in Didi cars without an adult.
Of the 651,856 people who took part in the survey, 56% felt that those under 18 should be able to hail rides alone. They believe that a safer ride lies more in stricter management of drivers rather than put restrictions (限制) on a passenger’s age.
However, some argued that no matter how excellent any safety measures are, they cannot completely stop crimes (犯罪). They also felt that guardians like parents should be responsible for children who have a weak sense of safety and self-protection.
According to a report in 2018, crime rates for internet ride-hailing drivers are 0.48 per 100,000 people, compared with the rates for traditional taxi drivers being 6.27, almost 13 times higher. An expert said, “People are usually less worried when their children take a taxi alone instead of using an internet ride-hailing service. But in fact, the latter is a safer choice.”
Wang Xiaolin, who is a lawyer, said it’s not reasonable to stop all teenagers under 18 using ride-hailing services when they do have such needs. “We can divide them into more specific groups. According to the country’s law on road traffic safety, children under 6 cannot use public transportation without an adult. It’s the same when it comes to car-hailing services,” Wang said, “But the company should be able to let guardians know the real-time driving route to ensure children’s safety,” he added.

【推荐3】Have you ever heard of satellites(卫星)? What are they used for?
Satellites are helping to forecast(预报) the weather now. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, where the weather forms. They send these pictures to the weather stations. So meteorologists(气象学家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change so that it can work better for people.
Nowadays, more and more countries have weather satellites. Nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive the new pictures, the meteorologists compare them with the earlier ones. Perhaps they may find the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say the weather will change soon. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the meteorologists could only forecast the weather for about 24 or 48 hours. Now they can make good forecasts for about two weeks. Soon they may be able to forecast the weather for more than two weeks or more ahead.
With the development of the society, weather satellites will work better and better in people’s life.

【推荐3】It’s known that green tea is a symbol of Chinese culture. Also, it helps to improve health in so many ways that some people think of it as a kind of medicine. Perhaps that is why the Chinese have been using it for more than 4,000 years to treat all kinds of medical problems. Today, scientists know that there are catechin, caffeine, vitamin C and theanine in green tea that are good for health.
Catechin is helpful for lowering (降低) cancer (癌症) risk. It protects the body from cancer-causing substances (物质) and slows the growth of cancer. Besides fighting cancer, catechin prevents serious health problems like heart disease.
Caffeine causes the heart to beat faster. That’s why it was once thought that caffeine was not very healthy, but studies suggest that there are also good reasons for drinking caffeine. Specifically, cafteine has to do with a lower risk for Parkinson’s disease and liver (肝脏) disease. Yet, caffeine also has some weaknesses. It can influence sleep and make people nervous, so experts advise teenagers not to have more than 100 ml of caffeine a day. This is about the caffeine of a small cup of coffee.
Vitamin C is something that the human body cannot make enough by itself. So we have to get it through food and drink. The vitamin may play a role in improving physical conditions to colds and the flu. Also, it helps people to get well more quickly from those illnesses.
Theanine is another healthy substance found in tea. It has been shown to lower stress, both mental and physical, and increase mind abilities. It is also used for preventing some brain diseases.
As you can see, green tea has many good values. Drinking it may help you stay healthy. Of course, as with any healthy substance, it is important to check if there are any bad influence as well.
