    Think stars don't move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move—they are just so far away that the movement is hard to see.
    But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities(奇特). It was located on the outer edge of the Milky Way, the galaxy(星系) we live in. The star was speeding away like nothing he'd ever seen. “It seemed unbelievable. No star in the galaxy has a speed like that,” Brown remembers. “I thought, oh my goodness, I have something kind of special here.”
    No one had ever seen a star like this one. What does a scientist do when the results don't make sense?
    Brown didn't give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called hypervelocity stars. Hyper means “above” and velocity has to do with speed. He and his team just found six more of these “above speed” stars, bringing to the total of 16. And, he says, he's found even more, and is just waiting for the scientific community to confirm them.

    For hundreds Of years, scientists have been trying to answer what things have an effect on people's emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don't know your emotions can be influenced by the weather as well.
    People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
    The weather can also affect people's emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.
I've always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook. Myspace—I've got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online business are run from one- room home offices. Others have hundreds of employee(雇员)spread across five different continent. Have you ever heard of Amazon. com, Yahoo. com?
My friends often said they got cheap textbooks off Amazon.com, or had a good deal(交易)on Steve Madden boots that were on sale at SteveMaden.com. Unfortunately for me, I continued my "e-commerceless"Web-surfing, unaware(不知道)of all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
"Why are all these packages arriving in the mail for you, Katy?" I asked her one day. Strange envelopes had been put on our doorstep for weeks now, each one always addressed to my sister and we all know little sisters should never be getting more mail than their elders!
"Oh, it's the things I ordered online!" she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
"How much did all of this coat?"
"Oh, only about $15in all!" She said excitedly. "Everything on eBay is on sale! It's way better than going to the mall."
I felt as if my entire life, there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.

In America, when people say ‘man's best friend', they don't mean another person. Instead, they are talking about a lovely animal—a dog! These words show the friendship between people and animals. Dogs and other pets can give joy to people's lives. Some people even leave all their money to their pets when they die!
Animals can help people, too. You can teach dogs to be the ‘eyes' for blind (失明的) people or ‘ears' for deaf (聋的) people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, they bring animals into hospitals for ‘visits'.
Americans have ‘Be Kind to Animals Week' in the first week of May. There are many pet shows during the week. Even if you don't live in America, you can also show your love to animals. How? First think about how animals make your life richer (更丰富). If you have a pet, take more time this week to play with it. Remember to give it nice food. If you don't have a pet, be kind to animals around you. For example, if you see a street dog, don't kick it. Just leave it alone, or make friends with it. If others around you do bad things to animals, try to stop them. As people, we must protect (保护) animals because they can't speak for themselves.

Hippos(河马) live in Africa(非洲). They are one of the world's largest land animals. Here are some interesting facts about them.

●Where are hippos born?

Hippos often give birth in the water. The hippo babies get out of water right after birth to take their first breath.

●How quickly do hippos grow up?

Hippo babies nurse both under water and on land for a year. Then they stop taking their mothers' milk but they are still with their mothers until they are eight years old. Then they move out.

●What do hippos love?

Hippos love water and they spend most of the day in it to stay cool. The Hippo can breathe, see and hear when its body is under water because its nose, eyes and ears are on the top of its head.

●Do hippos swim better than people?

Yes, they are great swimmers and they can hold(屏住) their breath for five minutes. Hippos can even walk under water along the bottom(水底) of rivers and lakes.

China isn't well known for its science fiction films, but recently a new film called The Wandering Earth has become a great success. It has earned over $697 million worldwide. It tells an amazing story of the Earth in danger, along with exciting scenes of spaceships and outer space.

The Wandering Earth is based on a story by Liu Cixin. In the story, the sun was dying out, people all around the world worked together to move Earth out of the solar system and sail Earth to a new star system. The film began with the early life of a young boy who was born just after the project started. The engineers pushed Earth away and built underground cities that were vast enough for all the other humans to live in. Yet the 2500 years' journey came with all kinds of dangers. In order to save the humans, a group of young people came out and fought hard for the planet.

China is playing an increasingly important part in the film industry. Its growing middle class has seen the rise of film market across the country, and Chinese viewers have become an important part of film industry. Hollywood Projects like Iron Man 3 specifically filmed more scenes in China for its market. Chinese film industry is keeping growing. Just as Americans want to get into the Chinese market, Chinese filmmakers are looking for the way to the international market.

According to The Hollywood Reporter, The Wandering Earth is China's "first space" film. Chinese science fiction writer, Anna Wu, says science fiction "is a new challenge for the Chinese film industry." Some Chinese filmmakers have achieved a great success at this kind of film, but most of them still have a long way to go.

Still, Wu notes that within China, "Not all the science fiction films have had success. It still takes time to accept science fictions, and that with the development of our country, people are getting busier, wealthier and more stressed," which creates a perfect environment for this new kind of film and television. The Wandering Earth, she says, is a good example. "I also care about the money it earns, which will affect the future of Chinese science fiction films."

If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G.The "G" stands for the "generation (代)" of your mobile phone network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won't just bring faster mobile Internet. People can use it to do many other things as well.

For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag (延迟). When the car "sees" an obstacle (障碍物), it sends he information to a data center and receives instructions. However, it takes time to send and receive the information with this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer according to CNN.

5G could also be used to power the Internet of Things (IoT). This means a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left.
