The Wentian space lab is expected to advance(发展) space science, technology and research. Wentian lab module(问天实验舱) will serve as a space life science research lab. And it will make use of the micro-gravity(微重力) in space to do many experiments that would be impossible on the ground. It will also be used for some basic researches on human’s journey from Earth into the space.

The world’s first space station was launched(发射) in 1971 and the International Space Station has scientists to do experiments there. These experiments were related to life science research in space, including research on treatment for many diseases as well as the effects on the human body of living in space.

There was a time when China had few chances to do such research, but now China can.

With a weight of 23 tons and a length of 17. 9 meters, Wentian is the world’s longest spacecraft. Besides, Wentian provides one more exit one more kitchen, as well as three sleeping zones for the astronauts. So they have enough space for living and working.

A review at the past 10 years will find a clear path for China’s space industry. The Shenzhou series of spaceships have progressed from IX to XTV. And the space station is finally coming into service. The Chinese are adding more footprints in space, for the common good.

On Monday, it was reported that Shenzhou XTIV had already entered the Wentian lab module. It heralds the start of a series of experiments that astronauts are to carry out in space.

They will also talk with school children by video. It is hoped that they will encourage more students to carry forward China’s space studies in the future.

Today's teens have grown up online. They make friends online. They do homework online. And surely they get their news online. But because they are so comfortable with the Internet, they seldom question the news stories online and pass along to their friends.

Now William Colglazier, a history teacher at a high school in America, is teaching his students how to think critically(批判性地) about online information and recognize(识别) a fake(假的) news story.

His idea came from a study on people's online reasoning(推理) at Stanford University. The study found that young people lack(缺少) ability to reason about the information on the Internet Most middle school students in the study could not tell the difference between an advertisement and a news story, and high school and college students fully trusted the websites ending in ".org".

The good news is that，according to Colglazier, once teens realize they've been cheated, they have strong will to tell truth from lies. "But they need some advice on how to find evidence(证据) and how to recognize when others use poor argumentation(论据)," he said. Some of the advice that Colglazier offers his students include moving off the site to find more information about the site, the writer's motivations(动机) and the organization behind the news story.

Colglazier shared some of his course with other teens in Teen Vogue, a famous magazine. He hopes more kids would take away some knowledge about thinking critically when they read news online. "The Internet is both beautiful and ugly," he said. "If people cannot tell real news from fake news, the results can be frightening."

I love snakes. My mom definitely does not. When she was a kid, snakes used to hide in warm spots under the furniture. So she grew up afraid she’d step on a snake. I grew up hoping I’d see one outside! In fact, lots of people who are afraid of snakes have never even seen one. So where does our fear come from?

Scientists wonder about this, too. Their experiments with adults, kids and even babies show that it’s complicated. People may not be born afraid of snakes, but we are born able to see them quickly. In tests with pictures, people picked out snakes faster than they could find flowers, frogs, and caterpillars. It wasn’t just snakes, though. People also found spiders and angry faces faster than “safe” things like flowers. It seems like we find things that might be dangerous to us faster than things that aren’t.

People also learn to fear snakes faster than we learn to fear many other things. We take our hints (提示) from other people’s scared voices and faces. Some scientists think we have evolved this way—faster to see snakes and faster to learn to fear them. After all, if we had to be bitten by a snake to learn that it’s dangerous, we might learn our lesson too late.

So why does it matter whether we’re afraid of snakes? It may not matter much to us, but it matters a lot to snakes. People protect animals they like, not animals they fear. Snakes may not be as cute as dolphins, but they’re just as important to the environment. Snakes eat insects that are pests to humans. Snakes are also food for other animals, so when we kill snakes, we’re hurting other creatures, too.

How do we overcome our fear to give snakes a chance? Scientists did a study recently where students of your age went on a field trip. Guides helped them find and capture snakes in the forest. Everyone could safely touch and hold the snake. It turns out that snakes aren’t so bad when you get to know them. Most people who were afraid of snakes before the field trip weren’t afraid afterward. In fact, snakes even became some students’ favorite animal. Hmm, maybe I should take my mom on the next field trip.

Remember: Always respect snakes, whether you’re afraid of them or not.

During the Tang Dynasty (618-907), Emperor Taizong asked the prime minister Feng Deyi to recommend talented people. However, several months p    61     and Feng didn’t recommend anyone. “I tried my best, but there are not unusual and well-rounded people at all,” Feng said.

“People are like utensils (器皿). What we n    62     to do is to make good use of their strengths. You cannot excuse yourself for not noticing talented people. How could you say that there are no talented people in our country?” said the emperor.

That’s t    63    . Each utensil or tool has its use. A knife is made to cut things w    64     chopsticks are made to pick up food. We can’t use a knife as a chopstick like a utensil, each person has a special strength. Nobody is perfect. We can’t e    65     a person to be good at everything.

With this idea in mind, Emperor Taizong d    66     many talented people of different backgrounds. He offered them i    67     positions, which helped them make the most of their talents. His talented people helped the society d     68     quickly and created a “golden age”.

A good e    69     is Ma Zhou, who grew up in a poor family. Ma gave a lot of useful advice, so Emperor Taizong offered him a position and promoted him many times. Ma helped the emperor deal with many problems and became a well-known great person in h    70    .

Paying for bus rides with plastic usually makes people think of plastic bus cards. But one Indonesian city has decided to accept plastic recyclable waste instead of money for city buses.

Surabaya, Indonesia’s second largest city, lying on the eastern end of the country’s main island Java, made this decision in April 2018. Now, locals can pay for their bus rides by putting plastic cups or bottles directly on the bus. A two-hour bus ride costs 10 plastic cups or 5 bottles.

Indonesia is the second largest ocean plastic polluter, producing up to 2.4 million tons of plastic waste into the oceans every year, according to a report. Only in Surabaya, nearly 400 tons of plastic waste is produced every day. The head of Surabaya’s transportation department (交通部门) said, “With this decision, we hope to raise public awareness about environment, especially people’s awareness about plastic waste.”

In Surabaya each city bus can collect up to 550 pounds of plastic bottles and cups every day. The collected bottles are sold to recycling companies and the money earned from it goes toward running the bus companies and providing money for green spaces in the city. This is certainly turning rubbish into a national treasure.

The decision is part of the city’s purpose to become plastic waste-free. In order to encourage local people to take buses, the city also added new Surabaya buses. The new buses are air-conditioned, comfortable and easy for elderly and disabled passengers to get on and off.

The program is well received. People in Surabaya said, “We can reduce waste so it doesn’t pile up at home because we can just bring it in and make good use of it. It is a win-win situation.”

This type of program can be a model for other worldwide cities and encourage citizens to recycle their plastic waste.
