【推荐3】Nowadays, countries are eager to get more electric cars on the road because moving away from gas-powered vehicles is vital to fighting climate change. China says that most new vehicles sold by 2035 will be electric. The United Kingdom will ban new gas-powered cars in 2030. One of the world’s major automakers, General Motors (GM), announced that it would stop selling gas-powered cars by 2035.

The key to an electric future is batteries. Automakers are racing to pack the most energy into the smallest one. The lithium-ion battery is what powers our mobile devices, which can be recharged again and again. Making these batteries has an environmental cost. Lithium is taken from the earth, like the oil used to make gasoline. But the long-term cost is much smaller. “Once you burn gasoline, you can’t recycle it,” says Jessika Trancik, a researcher at the Massachusetts Institute of Technology. “But when you use up a battery, you can still recycle the material.”

It’s up to governments to make electric cars accessible to everyone. National policies can help. In the United States, an electric Chevy Volt costs about $35, 000. Trancik says charging stations must also be made widely available. As part of an effort to fight climate change, America plans to build half a million of them in the US by 2030. She hopes enough charging stations will be built soon. “It’s important to put chargers where many different people can have access to them,” she says, “not just wealthier people.”

Last year, almost 5% of approximately 67 million new cars sold world widewere electric. For Venkat Viswanathan, a professor of Mechanical Engineering at Carnegie Mellon University, green electricity is part of the solution to climate change, and electric cars are just the beginning. He sees a future of solar powered homes and electric flying cars. “Soon, a plug in vehicle might be as cheap as a gas-powered car. It is now abundantly clear that electric is the future,” he says. “It will be a totally new world.”

【推荐2】Kids always have many doubts like: why do people have to die? Are mistakes always bad? Can you be happy and sad at the same time? Children often say that they lie awake at night thinking about things like why the world has the colors as it does, the nature of time and whether dream are real. These are not the kinds of questions that can be answered by googling them or asking Siri.

When children raise these questions, adults tend to respond with explanations that try to resolve the issue, at least temporarily. It’s natural to attempt to comfort a kid who is feeling puzzled by the world. But simple explanations may not be what the child wants. Sometimes, kids simply want to talk about their questions and thoughts.

Most kids start wondering about big questions almost as soon as they learn to speak, and they continue to think about them throughout childhood. Being full of curiosity about things that most adults take for granted, children all over the world are wide open to the mysteries in human life. But as they get older, kids ask questions less and less.

While children do need adult help and guidance, parents don’t always have to be in position of the experts providing the answers. Thinking with children about their bigger questions can make way for a more mutual kind of interactions. Because these kinds of questions tend not to have settled and final answers, discussions about them allow parents and children to wonder together. In this way, adults feel less pressure to be the experts.

Most of children have few long-held assumptions about bigger questions. Kids often suggest original and creative ways of looking at them. Talking with kids about what they are thinking without always feeling compelled to offer answers can help them explore their own concerns and ideas.

【推荐3】Taking IT and AI to the people

Putting aside employment prospects (就业前景)and the expectations of my parents, the major I’d most like to study is computer science.

    1    First, I have been interested in computers since 1 was a child. I like playing games and drawing and editing pictures using computer software, so I think that a computer science major would allow me to build on this interest. Second, I have found that I turn to the internet when I have a problem that people around me can’t help with. It’s a goldmine (宝库)of answers.

    2    We use the net to shop, chat with friends who live far away, and book tickets and hotel rooms when we travel. The net is so wonderfully convenient that 1 doubt that modern life would be possible without it.

If I do study computer science and internet technology as my major, after college I want to develop artificial intelligence products. They would add convenience to life.     3     They can facilitate our communication so that society can meet people’s demand for higher living standards.

If I could, I’d even like to develop my own games.     4    

However, it’s not easy to qualify for the world of IT.     5     Nevertheless, I am going to put in every effort to achieve the high standard that is required. I firmly believe that one day my dream will be fulfilled

【推荐1】Do you have imagination? Do you like to solve problems? If so, you could be the next great inventor(发明家). “But I’m just a kid,” you might say! Don’t worry about a little thing like age. For example, one famous inventor — Benjamin Franklin — got his start when he was only 12. At that young age, he created paddles for his hands to help him swim faster. Eventually, his creation led to what we now call flippers!

So you don’t have to be an adult to be an inventor. One thing you do need, though, is something that kids have plenty of. curiosity and imagination. Kids are known for looking at things in new and unique ways.

Jeanie Low invented the Kiddie Stool when she was just 11. It’s a folding stool that fits under the kitchen sink. Kids can unfold it and use it to reach the sink all by themselves.

At the age of 15, Louis Braille invented the system named after him that allows the blind to read.

Chelsea Lannon received a patent(专利)when she was just 8 for the “pocket diaper,” a new type of diaper that includes a pocket for holding baby wipes and powder.

【推荐2】The publication ofHarry Potter and the Half-Blood Prince pleases booksellers across China.   The British and American editions were No. 1 and No. 3 separately on the sales chart of the Beijing Xidan Book Building last week. The book’s poster is highlighted and news about the book can often be heard on the radio.

Why is the book so attractive to children? With curiosity, I got a copy of “Harry Potter”. At first, I wanted to glance over it and made some criticisms (批评). But, out of expectation, I have been deeply attracted by the magic world. On the other hand, one can’t help asking: Where is our own “Harry Potter”?

The Chinese nation has a history of 5,000 years. With a vast market of youngsters, China did publish many books popular among children. However, why are the present works not as good as those imported (进口的)?

There come two major reasons: Firstly, quite a number of children’s books are of strong sense of teaching, and lack interest and entertainment. Children often have a feeling of being “educated”. No wonder they don’t like them. Secondly, children’s reading materials involving “idiom stories” and “Chinese talents’ stories”, though always in different covers, are usually much the same. Some books are plagiarized. The authors take words, ideas from someone else’s work. One knows the ending as early as in the beginning. In final analysis, the authors of the books seldom take children’s requirements into consideration.

As a matter of fact, each child has his own wonderful imagination. They hope to understand the world and nature. Similarly they have their own choices. They dislike similar stories. even if the stories are excellent. First-class reading for children should be very interesting,which contains knowledge and the essence (精髓) of national culture, which are presented in children’s language.

Market is a touchstone for products. The theory also holds true for cultural products. It is hoped that the authors of children’s books can learn something from the good market of “Harry Potter” and write out more and better books loved by children.
