    Driverless(无人驾驶的)technology is quickly progressing with many cars being tested on roads around the world．Now, researchers in Singapore are testing a self-driving scooter，which has four wheels and a seat．It can move at a speed of up to six kilometers an hour．Researchers said the scooter was built with materials that did not cost much money．

    The scooter was developed by the National University of Singapore．Researchers at the Massachusetts Institute of Technology(MIT)also took part in the project．It was designed(设计)for people who cannot，should not or do not want to drive a car．It could help older adults，the disabled or people who are too young to drive．

Marcelo Ang，a researcher at the National University of Singapore，says the scooter can be especially useful for people who use wireless devices(无线设备)while walking on city streets，because there is a sensors(探测器)in it． “I'm sure you have experienced people who almost run into you while using their phones on the street．Would it be so nice to drive the scooter without worrying about the safety?”he says．Besides，developers of the scooter say it can work together with ride—sharing services to make trips completely easy and safe．

The researchers hope the scooter will reduce the need for cars，which can lower pollution and reduce accidents．

    Marcelo Ang says the scooter has completed many successful tests at the university．Kevin Xiangyu Hui，a university student．tested the scooter and said he found the ride was very smooth and safe．“When I sat on this machine．I felt really relaxed and it was really cool．”The scooter has yet to complete lots of road tests so it is not available to buy at present．

    Over 80G of the ancient forests have already been destroyed. Thousand-year-old trees are cut down just to make everyday goods. More and more wild animals are in danger now. Wild animals are our friends, and we cannot live without them. If we take no action, more and more wild animals will disappear in the future. It is time for us to save and protect endangered animals. Then what can we do? Here are some steps.

    Step one: Find out what animals are living near your place. Spend some time learning about the animals.

    Step two: Help to build more nature reserves and other wilderness areas. Protecting the living areas of wild animals is one of the best ways to help protect endangered animals. You can raise money for them or spend some time helping build nature reserves.

    Step three: Buy foods and goods that are made from materials which do not harm endangered animals or their living areas.

    Step tour: Join a local Wild Animals Club. You can take action to protect wild animals. There are many global groups that try to call on people to protect the environment by changing people's ideas and behaviours. Children, teenagers, teachers and schools from all over the world can help to save the animals. Everyone can do a little to help them, and every little bit of help is important!

The Netherlands needs thousands of new houses because the country {#blank#}1{#/blank#}(have) a growing population. Anyway, it may not have to build all those houses. Some of {#blank#}2{#/blank#}(they) can be printed.

 {#blank#}3{#/blank#}(recent), the government has been working together with a university and some building companies to build houses that are fully 3D-printed. As volunteers, an old couple has become the first people in Europe to move into such {#blank#}4{#/blank#} house.

With two {#blank#}5{#/blank#}(bedroom) and a big living room, the house was built layer(层) by layer, using a huge 3-D printer and special cement(水泥). After being printed out, the house {#blank#}6{#/blank#} (carry) by a truck to the building site, and a roof(屋顶) and windows were later added. It took around 120 hours {#blank#}7{#/blank#} (finish) this 3D-printed house. Usually, it takes about one or two years to build a house in the {#blank#}8{#/blank#} (tradition) way.

The couple will live {#blank#}9{#/blank#} this house for six months, with a monthly pay of 800 euros (欧元). The cost seems a little bit high, {#blank#}10{#/blank#} they think it is much cheaper than living in a hotel.

Do you know how many bones are there in your body? When you were a baby you had more than 300 bones, and now you have just over 200 bones. The number reduces because some bones join together as you g{#blank#}1{#/blank#}. Your wonderful bones work together to protect you and support your body. 

Many uses

Many bones protect your body. For example, the bone that makes up your head is called the skull. The skull surrounds your brain and protects it. 

Other bones are used to support the body. The bones in your feet allow you to w{#blank#}2{#/blank#}, and stand on your tiptoes. Your hands and feet have more than half of the bones in your body!

Biggest Bone

The longest and strongest bone in your body is in your leg. It is called the femur and it goes from your hip (臀部) to your knee. It is a very i{#blank#}3{#/blank#} bone because it carries all of your weight and helps you move from place to place. 

Smallest Bone

Would you believe the smallest bone in your body is in your ear? It is about the s{#blank#}4{#/blank#} of a grain (粒) of rice and is called the stirrup. When sound waves come into your ear the stirrup shakes back and forth, allowing the sound waves to reach your brain. When the waves reach your brain you h{#blank#}5{#/blank#} the sound. 

"Funny" Bone

Hah! The funny bone isn't really a bone at all. It is a{#blank#}6{#/blank#} a nerve (神经). When you hit the nerve that is near your elbow (肘部), it really hurts or tingles. The funny bone probably got its n{#blank#}7{#/blank#} from the bone that is above your elbow. That bone is called the humerus, which sounds like the word "humorous", meaning "funny". 

 Riding a Mobike on the street, you might hear some people speaking Chinese aloud. Turning to the right, you see a Sichuan- style restaurant. After walking into a store, you see that Huawei smartphones are on sale. But you' re not in China- you' re in Manchester in Britain. In fact, you might see similar things in many other cities.

 Chinese products have been going all over the world. Chinese food has been enjoyed in Western countries for a long time. To meet local people's tastes, Chinese restaurants have made some changes to the dishes." One example is the meat." said Yin Hang,a Chinese student who is studying in Australia." We like to eat meat with the bone(骨头) in, but people here don't. So the local Chinese restaurants provide big pieces of meat without bones, even for fish."

 Some Chinese brands are also becoming more popular. It is reported that in many cities in Europe, many stores sell TCL televisions, Haier fridges and Lenovo computers. More than half of US- owned drones(无人机) are Chinese models, according to China Daily. They' re not only made in China, but also designed and developed in the country.

 In the past, most Western people thought Chinese products were cheap and unreliable. But now, things have changed greatly. More people trust Chinese brands." Made in China" becomes cool." They are beautiful and offer something special that American phones don't have." an article on CNN once said about Chinese smartphones.

 As it is said, Chinese government has been trying its best to improve its national brands of all kinds to meet the needs of modern life.
