Robots have built a big house in Switzerland using 3D-printed materials. It is the first house made by robots for people to live in. It is more environmentally friendly and safer than man-made houses.

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

The big house was built completely from robot-made materials. It used 60% less cement（水泥）than a man-made house. Its ceilings（天花板）were made with a 3D printer. There are 35 parts in the house and each one was built in 60 to 90 minutes. It means that the robots built the full house in just 48 hours.

It is not the first time for robots to build houses. The Chinese used 3D printers to build 10 houses in a day in 2014. They created a building the next year. And last year Italians built a house in just 48 hours.

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

3D printers are certainly the superstar today---they are being put to all kinds of uses, including creating model cars for movies. However, none of these ideas are as crazy as the one suggested by Anjan Contractor, who believes that they will be the key to ending world hunger（饥饿）.

If you think that sounds a little crazy, you are not the only one, but after hearing scientists, the idea seems to become true.

According to scientists, food will become extremely expensive and possibly, even out of reach, for billions of people in the future. It means billions of people won’t have enough food.

This is where 3D printers may save the day. Anjan, an engineer says that the only way to support the large population will be to provide every kitchen with a 3D printer and print out meals.

More importantly, it would be to make the basic food from things that we now do not think can be eaten. Anjan thinks that we could easily get the meat protein(蛋白质) from insects（昆虫）. Similarly, the vegetable nutrition（营养）could be made from greens like grass. Would you want to try 3D printed food?

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Most of us don’t think about food until we start feeling hungry, but eating is important in life. To talk about food and eating is to talk about one of the most common subjects we know. Eating is just like breathing or sleeping every day.1.

However, what, where, when, how, and with whom we eat say a great deal about who we are. Do you use chopsticks? Do you hold the knife backward? Do you chew with your mouth open?

2. They are messages even when we are not trying to say anything. Food and the ways we eat it, like clothes and the way we wear them, tell who and what we are.

3.　 We usually have strong feelings about our childhood foods. Foods we learn to like in our early years probably have a special meaning for us forever because they are connected to people and things we love. Mom’s cheese or the way Dad cuts the bread crusts just right bringing up feelings of love and comfort.

People use food and eating to mark the seasons and the important moments in life (such as growing up and getting married).4.Sometimes people even explain why they eat certain things on certain days. Americans do that sort of explaining at Thanksgiving. They eat Turkey, com, and Indian pudding because their ancestors ate them at the first Thanksgiving. Those foods mean something to Americans.

As you can see, food and eating mark people’s shared experiences, but they can also mark the differences.5.

A.In that sense, we truly are what we eat.

B.It’s so ordinary that it doesn’t receive much notice.

C.People will eat different foods for different holidays.

D.Your health will be decided by what you eat.

E.We learn our eating habits very early in life.

F.The food we eat helps us grow in different ways.

G.All these eating habits say something about you.

Experts in nutrition suggest that we should eat at least five different kinds of vegetables and fruit a day. They are very necessary for our health and help our bodies work well. They can help reduce the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious. 1.

It's easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons：

2. You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.

You may want to cut down on your “food miles”—the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth. 3.

Homegrown food is likely to be healthier. Food producers often use fertilizers and pesticides which can end up in your food. If you grow your own, things are different. 4. You might also choose to grow some traditional vegetables and fruit. These often have more important things that keep you healthy.

5. And you can grow your own even if you only have a small backyard. Some food can grow well in pots, including tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage and a small plate under them to catch drops of water.

A.Best of all, you can grow your own!

B.That's not so good for you, or for the planet.

C.Food that you grow yourself is always fresh.

D.If you have a large garden, growing your own is easy.

E.You can control what goes on and into the food you eat.

It's a common belief that fish can't remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.

In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish sill went to the same place where they first got food.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains(容纳) safe food, they will be able to go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.

So next time you are watching your pet fish from outside the tank, perhaps you should feel close to them-they may remember who you are.

1.We often feel sorry for fish because __________.

A.they have bad memories B.they can't remember anything

C.they are often used for research D.every moment in their lives is new

2.Why did the researchers carry out the research?

A.To know if fish can find food easily. B.To find out if fish have better memories.

C.To tell us fish can live for days without water. D.To show fish can live long without eating things.

3.What does the underlined word "tank" in Paragraph 2 mean?

A.A kind of fish food. B.A kind of hiding place.

C.A container for holding water. D.A container for keeping fish.

4.Which is true according to Trevor Hamilton?

A.Fish know where to get food. B.It's easy for fish to live in the wild.

C.A good memory can make fish safer in the wild. D.Fish are often in danger when they look for food.

5.Where does this article probably come from?

A.A story book. B.A science magazine. C.A news report. D.A travel book.

Technology is developing fast and it has become an important part of our life. 1 那么未来的世界会是什么样子?

3-D food will be both delicious and nutritious. We can simply use3-D printers to print some basic materials. 2 Scientists believe that we just need to turn on a printer in the kitchen and then we can enjoy our favourite food.

3 5G网络将允许更多的人获得信息。 Big companies like China Mobile and China Unicom will start to offer 5G network. It is said that promises download speeds 10 to 20 times faster than 4G.

Underwater cities will provide more space. The earth is becoming more and more crowded. We may turn to underwater homes, which will be built as low as 15 kilometers below the sea.

4 Space tours will be a piece of cake. For us common people on the earth, the dream of travelling around space will come true. In the coming years, spacecrafts will be as popular as buses, trains and planes. We can leave our home and enter space to take a trip. And we will even get used to living there.

A robot will be a part of life. Robots can do many of the same things as we humans do, like driving cars. 5 But they will be used in other areas as well. They will be able to think and even tell the difference between right and wrong.

In a word, just as Jules Vemne said, “Anything one man can imagine, other men can make real.”
