Shenzhou 13 manned spacecraft landed successfully on April 16, 2022. Three Chinese astronauts, Zhai Zhigang, Wang Yaping, Ye Guangfu came back to the Earth. They s    1     in space for six months. It is the eighth time for Chinese to visit space after Yang Liwei went as the first Chinese 18 years ago. These special “v    2    ” took fantastic photos in space, just like taking trips there.

Can common people go to visit space like them? The answer is “yes”. On September 15, 2021, Space X sent four common people into space. The four spent three days in space. In July, 2021, 70-year-old British billionaire (亿万富翁) Richard Branson and 57-year-old American billionaire Jeff Bezos, both flew into space. But some think these trips are for the super r    3    . With the sky-high prices, most common people should give up their space dreams. However, US flight engineer Bobak Ferdowsi believes the price will come d    4    . Maybe in 10 to 15 years, it will be a choice between “Do I buy a new car or do I go to space?”

Even if we can’t have a space trip now, we had a science class from space. The woman astronaut Wang Yaping, the space teacher, gave us such a l    5     just as she did eight years ago. That was great fun, wasn’t it?

We will also be able to e    6     a space movie. A Russian movie team lived on the International Space Station from Oct 5 to 16 to film the movie Challenge. It’s the first time a movie was made in space. Do you look forward to seeing the wonderful film?

On Oct.16th, 2021, China sent a spaceship (the Shenzhou-13) into the space, marking the start of     1     longest spaceflight of China. Nine hours later, the three members—Zhai Zhigang, Wang Yaping and Ye Guangfu entered the station’s core module (核心舱), named Tianhe. They started     2     (they) six—month journey inside the station from then on.

The mother of a 5-year-old girl, Wang Yaping is China’s     3     (two) woman astronaut to take part in a spaceflight. She    4     (take) part in the Shenzhou-10 mission (使命) in June 2013. She is the first Chinese woman     5     (enter) a space station and is also the first Chinese woman to do a spacewalk.

A lot of work will be done     6     the three astronauts, according to Pang Zhihao, a spaceflight scientist in Beijing. They will check     7     the spaceship can work well in a bad environment during a long-term flight. Mr.Pang said that women astronauts actually have 8.     8     (many) advantages than men astronauts. “Women are usually more sensitive (敏感) and careful in many     9     (way), and they are better at communicating, which are useful in long-term flights. And a woman astronaut always     10     (bring) more joy to a difficult mission.” Pang said.

When Goldie Nejat began developing robots in 2005, she spent much of her time knocking on doors to let people know how her robots w    1     , but few showed interest. “But now, it’s different.” says Nejat, “People calling from around the world ask when my robots are going to be r    2    .” Nejat’s robots are made to meet a growing n    3    : care-giving for the old. The population(人口) of the people over age 80 will be 426 million in 2050, three times l    4     than that now.

Such robots could be especially useful for patients with Alzheimer’s disease(阿兹海默症). They can help with everyday activities from preparing food to telling patients to take m    5    .

Some w    6     that care-giving robots might cut down human communication and make more humans lose their jobs. “But they are made to help humans not to take the p    7     of them.” says Brian Scassellati. He tested robots with different patients, and found that daily communication with robots can help children with autism spectrum disorder(自闭障碍症) i    8     social skills.

As the field grows, scientists try to u    9     human-robot relationships better. Are robots useful because they don’t have f    10     and don’t give opinions? “One thing is clear,” Scassellati says, “robots help people a lot.”

On Dec 9, three Chinese astronauts who are working aboard the Tiangong Space Station, gave a lecture above Earth and showed millions of students their life there. They also did some fun s    1     experiments. Let’s take a look at some of them.

Use it or lose it

The human body grows with the pull of Earth’s gravity (重力). But in space, our bones and muscles don’t need to s    2     our body’s weight. This will cause bone and muscle loss. It is said that astronauts can lose up to 20 percent of their muscles after just a couple of weeks. That is dangerous for astronauts because they will be too w    3     to work.

Astronauts have different ways to prevent this. During the lecture, Zhai introduced a special uniform Ye was wearing. It’s called a “penguin suit”. It can keep their muscles strong.

Wang also showed students how she walked on a treadmill (跑步机) and rode a bicycle. Astronauts usually e    4     with these tools every day to keep their body strong.

Space water is different

During another experiment, Wang made a water film (膜). Then she added more water drops onto the film to make it a water ball. But this can n    5     happen on Earth. Why?

We need to first u    6     the surface tension (表面张力) of water. Surface tension is like a “skin” of water. The “skin” is there because water molecules (分子) are drawn to each other. One example on the Earth is that some bugs (昆虫) can “walk on water”. Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in space, the “skin” stays much stronger and the water ball will not b    7    .

Space water is different in many other ways from that on Earth. For example, water will not flow downward if you try to pour it into a cup. If astronauts cry, the tears will not fall down. They have to wipe them away!

Robots have built a big house in Switzerland using 3D-printed materials. It is the first house made by robots for people to live       1    . It is environmentally friendlier and       2     (safe) than man-made houses.

The creators say the future of building will     3     (influence) by the big house. “This is a new way of seeing architecture（建筑）,” said one of the creators. “How you build is important.”

The big house was built     4     (complete) from robot-made materials. It used 60% less cement（水泥）than a man-made house. There are 35 parts in the house, but some     5       (wise) robots built each one in 60 to 90 minutes. It means     6     the robots built the full house in just 48 hours.

It is not the first time for robots     7     (build) houses. The Chinese used 3D printers to build 10 houses in a day in 2014. And also     8     created a building the next year. Last year,     9     (Italian) built a house in just 48 hours.

Scientists say one day they could send robots to build houses on     10     moon. We are curious about how we're building for the future.

8 . When we discuss inventions, many of us think of some important things such as planes, trains and computers. In fact, many inventions are c    1     and they are often used in our daily life. However, we even don't know w    2     invented them.

There are a lot of things in our schoolbags, i    3     pencils, rulers, books and so on. None of them grow in the field. People make them in factories. They look common today, but hundreds of years ago no one knew about them. Who invented them? Where were they invented? We aren't sure. However, we should thank the inventors. Their inventions are so important to us. We couldn't e    4    such a wonderful life without their inventions.

Some of the inventions have changed not only our life but also the w    5    world, such as the telephone, the TV and the computer. We use them every day, but most of us don't know the names of the inventors. Should we remember the inventors? We can remember so many movie stars and pop stars. Why don't we pay more attention to the scientists and inventors? We should look on them as stars in our eyes!

9 . The third long March-5 rocket, China’s largest carrier rocket was     1    (success) launched(发射) from Wenchang Space Launch Center in Hainan Province on Dec. 27, 2019. The rocket     2    (name) Long March-5 Y3. It left the ground from the launch center at 8:45 p.m., carrying the Shijian-20 satellite, the     3    (heavy) and most modern communications satellite of China. About 2,220 seconds later, the satellite was sent into its     4    (plan) orbit(轨道).

The Long March-5 rocket made its first flight on Nov. 3, 2016 from Wenchang. However, the     5    (two) largest rocket, Long March-5 Y2, experienced a failure on July 2, 2017.     6    (compare) with Long March-5 Y2, the new rocket Long March-5 Y3 has shown more than 200 technological improvements.

Qu Yiguang, director of the Long March-5 Y3 research team, said, “Under great pressure, the research team has put all the efforts into the rocket over the past two years. We are very     7    (pride) that we can take part in the development of the Long March-5 rocket, which shows the highest level of China’s rocket technology.” After over two years of     8    (silent) in Wenchang, the Chinese welcomed the return of the “king” with excitement.

Since the Long March-1 sent China’s first satellite into space 50 years ago, the Long March series rockets     9    (complete) 323 flights. Over the past years, China’s rocket technology has been greatly improved. With the success of the Long March-5 Y3 rocket, China     10    (see) a busy year in space activities next year.

10 . Today there are already robots working in factories. Some can    1    (help) to build cars, and they do simple jobs over and over again. Fewer people will do such jobs in the future    2    they are boring, but robots will never get bored.

Scientists are now    3    (try) to make robots look like humans and do    4    same things as we do. Some robots in Japan can walk and dance. They are fun to watch. However, some scientists believe it will be    5    (difficulty) to make them really think like a human.

Scientists also believe that there will be    6    (many) robots in the future. These new robots will have many different    7    (shape). Some will look like humans, and others might look like animals.    8    India, scientists make robots that look like snakes. If buildings fall down with people inside,     9    (this) snake robots can help look for people under the buildings. This was not possible 20 years ago, but computers and rockets also seemed    10    (possible) 100 years ago. We never know what will happen in the future.
