【推荐1】Most children don’t enjoy doing housework. They like playing computer games rather than cleaning the rooms. But in Australia, Jim and Robert’s mother, Mrs. Black, has good and proper ways to get their children to do housework.

Here is an example.

“Mom, have you worked out next week’s housework? Let Jim and me choose the cards. I can’t wait. It’s fun!” When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “sweep the floor, clean your bedroom, help mom cook, wash vegetables, make beds, feed the fish, cut the wood, clean the bathroom” and many others. Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the weekday task board. Jim likes to clean the bathroom, so he picked up the card “clean the bathroom”. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards.

To help the children do housework, their mother thought hard and came up with this idea. Of course, the parents did the housework on the weekends and left Jim and Robert two days free.

【推荐2】These years, big changes to city life in China have attracted the world’s attention. Among them, four stand out. They are famous as “China’s four great modern inventions”.

Online shopping

China has many big online shopping platforms, such as Taobao, Tmall and JD. com. They have made online shopping a lifestyle choice for many people in China. Taobao even started “online shopping festival” on Nov. 11th. It’s reported that Taobao and Tmall may have more than 800 million goods. Their company Alibaba has developed into the world’s largest e-commerce（电子商务）company.

Bike sharing

Bike sharing is not a new idea. But China has given it a whole new meaning. It encourages people to ride the public-sharing bikes over short distances, aiming to solve the “last mile” problem in big cities. We use mobile apps（移动应用程序）or cards to unlock bikes. We can leave the shared bikes at any bike station. This makes bike sharing much easier.

Cashless payment

In China, now you don’t need cash or bank cards to buy things. You could just pay with your mobile phone. You can scan（扫描）a store’s QR code（二维码）to pay. Even a fruit seller on the roadside has a QR code for WeChat Pay or Alipay.

High-speed trains

On September 21, 2017, China’s new high-speed train Fuxing made its first run from Beijing to Shanghai. It ran at a speed of 350km/h. This makes it the fastest train in the world. China has the world’s longest high-speed railway network. It’s more than 22, 000 kilometers.

【推荐1】Shelly is a cute girl. She is 10 years old. Today is August 30, the day before the school day, Her mother takes her to her new school for the first time. They meet Shelly’s new teacher, Mrs. Miller.

Mrs. Miller says, “Welcome to our school, Shelly. I am your English teacher. ” Shelly loves her new teacher very much. She then knows what she can do at school from Mrs. Miller.

The first class starts at 8:00 in the morning from Monday to Friday. Students usually read and write in English class. After that, they have a math class at 8:50. Math is a little difficult but very useful. After 40 minutes, students can go out to relax for half an hour. Boys and girls all love it! They can do many kinds of activities like playing basketball, playing soccer and telling stories. At ten o’clock, students have history class for 40 minutes. The history teacher always tells them interesting stories about famous(著名) people. After that, it’s time for science class. It’s Mr. White’s class. He is very strict. Students must be on time!

Students can eat lunch in the dining hall at 11:30. Then they can take a short rest. At 1:30 p.m. they need to go to the computer room to have class. There they learn how to use the computer. At 2:20 p.m. they have music class. In the music class, students can sing, dance, play the guitar or play the violin. They can go home at 3:00 in the afternoon.

Many environmental groups are warning that oceans of the world are in great danger．In the past 50 years，the number of water with zero oxygen（氧气）in the open ocean has increased more than four times．In the near coast water bodies，including the river mouth and seas，low﹣oxygen areas have increased more than 10 times since 1950．Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms．To stop the drop，the world needs to control in both climate change and nutrient（养分）pollution．

Oxygen is a must to life in the oceans．The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment．

This is the first time for the scientists to take such a deep look at the causes，results and solutions to low oxygen worldwide，in both the open ocean and the near coast waters．About half of the oxygen on Earth comes from the ocean．However，mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters，where oxygen is too low to support most sea life．

In the areas traditionally called "dead zones", like those in Chesapeake Bay and the Gulf of Mexico，oxygen drops to levels so low that many animals have trouble in breathing and die．As fishes run away from these zones，their living areas become smaller and smaller．But the problem goes far beyond "dead zones"．Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death．Low oxygen also can cause the release of dangerous chemicals．Although a few animals can grow well in dead zones，overall biodiversity（多样性）falls．

【推荐3】Mount Qomolangma, located at the China-Nepal border(边境), known as Mount Everest in the West, is the world's highest peak(峰). A Chinese surveying team reached the top on Wednesday morning to make serious surveys there.

It is the third time for the team to head to the world peak within this month. The first two failed due to the change of weather that brought heavy snow.

Since the founding of the People's Republic of China in 1949, Chinese surveyors have done six rounds of measurements(测量) and scientific research on Mount Qomolangma and got the height of the peak twice in 1975 and 2005, 8,848.13 meters and 8,844.43 meters.New technologies were used in the latest survey, such as the Beidou-3 Navigation Satellite System(北斗三号导航卫星系统).

This year is the 60th year of the first successful expedition(远征探索)to Qomolangma and the 45th year of China's first accurate measurement(精准测量) of Qomolangma's height.

【推荐1】Do you know where J.K.Rowling wrote the Harry Potter books? She wrote the first books in a coffee shop. Was it because she felt more creative when working there. The answer might be yes!

Scientists from the University of Illinois found that moderate(适度的) noise can make people more creative, the New York Times reported.

Scientists did a test on students.They divided them into four groups. They then asked the students to do certain tasks including creative thinking. But each group did the task with different volumes(音量)of background noise.

They found that students did best when working under moderate noise--70 db. This is about the same volume of background noise in a cafe. Students did worse in low noise(50 db ). This is the volume of a quiet room. They did worst when in a high-noise (85 db) environment. This is the noise level in a factory.

"Noise makes people not focus on the problem, while moderate noise can make people just enough so that they think more creatively. It helps you think outside the box, " Race Mehta said, one of the lead researchers in the study.

Working in a very quiet place can help us pay attention. But it also stops us from thinking abstractly(抽象). However, the scientists said that when you need to do some things, like correcting a paper, a quiet place is better than a noisy one.

【推荐2】Here is a dog with a lantern (灯笼)in his mouth, he is looking for his master(主人).

Carlo, a lovely dog, had been taught to be useful. The roads, in the place where his master lived, were often so bad that it was not safe for any person to go out without a light on dark nights.

So Carlo's master taught him to carry a lantern for him at night; and he did it as steadily(稳固地) as any boy could have done.

Carlo never trotted(小跑) too far before his master so that the bright light of the lantern might guide his master's steps.

When he came to a deep rut(车辙)or hole in the road, he would turn round to his master, seemed to say,"Take care, there is a hole here. "

The dog's master lived about a mile from the town; and when he could not get home before dark, Carlo used to be sent to him with the lantern. Carlo knew where to go. He also knew the road which his master would take.

But Carlo didn't always find his master right away. When he reached the town, he would run off to a house where his master often was. Still holding his lantern, he would scratch at the street-door with his feet and bark(吠叫); as much as to say, "Here             am I.Master, with the lantern, are you ready for home? "

Someone would perhaps come to the door and say "Your master is not here. " Carlo would growl(嘟哝), seemed to say, "Then he is somewhere else, and I must find him. "He would then run off to one house after another, until he found his master, then the             two went home together.

Do you know the story "The Boy and the Starfish"?

It goes something like this: A man is walking along a beach. He sees a boy putting starfish back into the sea. He tells the boy that's not helpful, "There are thousands of starfish on this beach. You can't save them all. You can't make a difference." As the boy puts another starfish,he says to the man, "It's going to make a large difference to this one!"Members of an after—school program in New Hampshire, liked the story so much that they named their club after class!

The "Starfish club" members do a lot for shelter（收容所）animals, but want to make a difference to other animals too. They learned that a boy in Massachusetts helped get a law（法律） passed. The law bans（禁止）the sale of shark fins（鱼鳍）in this state. The kids in the club decided to try to do the same in New Hampshire.

People cut off the fins of sharks and then put the sharks back into the sea to die. The fins are sold and made shark fin soup. Each year tens of millions of sharks are killed for their fins.The club members talked with lawmakers but finally, the law wasn't passed."My friends are working very hard," says 10—year—old Payton Paradis. "I am sad that the law wasn't passed, but I hope we can call on many kids around the world to keep trying, no matter what the problem is. And remember: Fins are on sharks, not in soup!"
