Looking good can matter a lot when you are a teenager. Of course the budget(财政） matters a lot, too. Luckily, fashion trends (流行趋势) in the UK mean that getting the right image doesn't have to cost the earth. Here's a quick guide to which looks are hot this year.

    For girls, the 70s are back. Wide-legged jeans, platform shoes and skirts that reach the feet are again in fashion among UK teens, topped off with colored, shining eyeshadow. Girls can have fun mixing and matching bright shades. Colors like pink, orange and light yellow-green are all perfectly fit. Shorts and mini-skirts are still popular in cold weather. By wearing a pair of tights underneath ( 在..底下), girls can stay warm as well as fashionable in the winter.

    How about boys? To look lively, fans of skateboards and snowboards can dress in skinny jeans accompanied by a T-shirt topped off with a baseball cap or a woolen hat. Music is often an inspiration for fashion, and hip-hop music fans like to dress in baggy jeans, T-shirts, baseball caps and sneakers. For those who can afford it, designer clothing is a must, especially if the logo is showing.

    More student than ever before are taking a gap-year (间隔年)before going to university.It used to be called the “year off” between school and university.The gap-year phenomenon originated(起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.

    This year, 25,310 students who have accepted places in higher education institutions have put off their entry until next year, according to statistics on university entrance provided by University and College Admissions Service (UCAS) .

    That is a record 14.7% increase in the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. “Students who take a well-planned year out are more likely to be satisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible,” he said.

    But not everyone is happy. Owain James, the president of the National Union of Students(NUS), argued that the increase is evidence of student had ship – young people are being forced into earning money before finishing their education. “New students are now aware that they are likely to leave university up to ￡15,000 in debt. It is not surprising that more and More students are taking a gap year to earn money to support their study for the degree.NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation periods,”he said.

    Many facts suggest that children are overweight (超重的) and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

    Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

    There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

    There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

    The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.

    I recently posted a picture on Facebook from the movie Mad Max, a film where two groups race through the desert in steam punk vehicles, and wrote, “Actual picture of my way to work today.” It was meant to be a joke because of the sandstorms in Beijing, but one of my friends from back home thought it was real.

    I couldn't imagine how they could think that is actually what China is like. China has so many more conveniences and advantages than the West, and many of my friends agree. “I don't know how I will be able to deal when I go back home,” said a friend who is about to end her gap year in Beijing. “I've become so spoiled in China.

    China seems to be leading the way in innovation and convenience for daily life. Back home I could never shop, pull out my phone and scan a QR code to pay.

    There have been rumors of starting bike sharing in my hometown for years with little success while bike sharing suddenly appeared in Beijing overnight. I just step outside and scan a code, and I am on my way.

    Going out to eat with a group of friends back home was troublesome for both the group and the servers. Splitting checks and swiping (刷) 10 different cards or making change for each person in the group can be a pain. But with China's WeChat, you can quickly send your friends your part of the bill.

The list goes on...

    When I first arrived in Beijing, I was dead set on leaving in a month. That month has come and gone. Now, when someone asks me when I'm coming back, I think to myself, “Who knows?”

    While my friends think I'm riding through the desert on a motorbike, I am actually taking a “Didi” for what is the equivalent of $5 in the US.

    With all the conveniences and technology here, I may never want too go back.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as even when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials(尝试) increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables(乘法口诀表) are an exception(例外) to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming(突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

As the world struggles to deal with the climate crisis, some companies are working to remove polluting carbon dioxide from the air. {#blank#}1{#/blank#} But two US companies have recently made important progress. 

Scientists say large amounts of CO₂ must be removed from the CO₂ atmosphere and stored. {#blank#}2{#/blank#} But there's so much CO₂ in the atmosphere that just planting trees and protecting forests won't solve the problem. And, when plants and trees die, the carbon they've stored gets released again. 

That means humans need to come up with ways of removing carbon from the air and storing it. This is called Direct Air Capture (DAC). The science of removing carbon from the air is challenging, and it's still pretty new. {#blank#}3{#/blank#}So one puzzle for these companies is how to remove carbon without creating more pollution. 

A company called Heirloom has just opened the first DAC plant in the United States. The company heats up the limestone to separate out the CO₂, which is concrete. The process is extremely expensive. {#blank#}4{#/blank#}That's a tiny amount compared to how much carbon needs to be removed from the atmosphere, but the company says it hopes to remove a billion tons per year by 2035. 

 {#blank#}5{#/blank#} Some people worry that it will take too long for DAC technology to become powerful enough to make a difference. Others worry that focusing on removing carbon could take attention away from more important climate actions, like switching from fossil fuels to renewable energy. But experts say the decision isn't to do one or the other. The world needs to end fossil fuel use and pull carbon out of the air. 

A. Plants and trees do this naturally.
B. That's a huge and challenging goal.
C. Not everyone is excited about carbon removal.
D. Graphyte is another US company working on DAC.
E. The new plant can remove 1,000 tons of CO2 a year.
F. Most DAC processes require a large amount of energy.
G. As a matter of fact, CO₂ is just a small part of the gases that make up air.
