    Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

    Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

    While the findings are surprising, they also offer some explanations.

    Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

    So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over-compensate for the missing calories.

    A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine. "They may be free of calories, but not of consequences."

(1)、People drink diet sodas to ____________.
A、enjoy its taste B、stay in fashion C、achieve weight loss D、gain more energy
(2)、The new study suggests that drinking diet sodas ____________.
A、causes people to become heavier B、helps people to be healthier C、makes people much thinner D、offers people more calories
(3)、We can learn from the passage that ____________.
A、regular sodas make people lose more weight B、diet soda drinkers tend to eat more food C、diet sodas do help reduce calories D、most blood diseases come from diet sodas
(4)、The underlined word "They" in the last paragraph probably refers to "____________".
A、sweeteners B、diet sodas and artificial sweeteners C、sodas D、diet soda drinkers and sweetener takers

    It was New Year's Eve. Everyone in the city was getting ready for the three-day celebration, including the gardener of the king's garden.

    There was a large group of monkeys living in the garden. They always followed the advice of their leader, the monkey king.

    The gardener wanted to celebrate the New Year's holiday, just like everybody else, so he decided to hand over his duties to the monkeys.

    He went to the monkey king and said, "My honorable friend, would you do a little favor for me? New Year is coming. I wish to celebrate it. So I must be away for three days. Here in this lovely garden. There are plenty of fruits and berries and nuts to eat. You and your subjects may come and eat as much as you wish. In return, please water the young trees and plants while I'm gone."

The monkey king replied, "Don't worry, my friend! We will do a terrific job! Have a good time!"

    The gardener showed the monkeys where the buckets were kept. Feeling confident, he left to celebrate the holiday. The monkeys called after him, "Happy New Year!"

    The next day, the monkeys filled up the buckets, and began watering the young trees and plants. Then the king of the monkeys addressed them,"It is not good to waste water. Therefore, pull up each young tree or plant before watering. Inspect(检查)it to see how long the roots(根)are. Then give more water to the ones with long roots, and less water to the ones with short roots. That way we will not waste water, and the gardener will be pleased!"

    Without a second thought, the other monkeys followed their king's orders.

    Meanwhile, a wise man was walking by the garden. He saw the monkeys pulling up all the lovely young trees and plants, measuring their roots, and carefully pouring water into the holes in the ground. He said, "Oh foolish monkeys, what do you think you're doing to the king's beautiful garden?"

    They answered, "We are watering the trees and plants, without wasting water! We were commanded to do so by our king."

    The man said, "If this is the wisdom of the wisest among you — the king — what are the rest of you like? Intending to do a worthwhile deed, your foolishness turns it into disaster!"

    Drive through any suburb in the U.S. today,and it's hard to miss the bins that have become companions to America's trash cans.Recycling has become commonplace,as people recognize the need to care for the environment. Yet most people's recycling consciousness extends only as far as paper,bottles,and cans.People seldom find themselves facing the growing problem of e-waste.

    E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced devices,and the majority of them end up in landfills(垃圾填埋地).Some people who track such waste say that users throw away nearly 2 million tons of TVs,VCRs,computers,cell phones,and other electronics every year.Unless we can find a safe replacement,this e-waste may get into the ground and poison the water with dangerous toxins(毒素),such as lead, mercury,and arsenic.Burning the waste also dangerously contaminates the air.

    However,e-waste often contains reusable silver.gold.and other electrical materials.Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals,which can destroy ecosystems.

    A growing number of states have adopted laws to ban dumping e-waste.Still,less than a quarter of this refuse will reach lawful recycling programs.Some companies advertising safe disposal(处置)in fact merely ship the waste to some developing countries,where it still ends up in landfills.These organizations prevent progress by unsafely disposing of waste in an out-of-sight,out-of-mind location.

    However,the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner,better place for us all.

    There are many reasons why I encourage people to travel, and I know that the experience will make one a better person.

    I remember when I was travelling I began to know the world better. The world is not just about me, my small town and home. Although you will meet different people from all over the world, you will realize that people are similar in their dreams, hopes and feelings. Enjoy exploring the different cultures, and you will also find that people are different in some of the things they do and how they live. Once you understand their ways, it need not be strange or scary. Often we read stories about other cultures in books. Only when we visit their areas do we find that those stories are something wrong.

    One thing you may find out is that there are problems all over the world. We can't just get money to send to these areas and hope that will work them out. The world should get involved(干预)and help wherever there are problems. People everywhere should be given a chance. It is so easy to ignore this if one does not travel and explore. One can look around and see that so many people have many challenges worse than ours. One can realize that sometimes our biggest problems are not that big after all.

    On your journey you will meet lots of new friends. Talking to strangers and finding about their lives is a great way to spend your time. you will certainly be more confident after having to cope with problems and make many decisions along the way.

    When you travel, you have to be on your own in some situations. You will surprise yourself by how well you can do that. All your special experiences could make an interesting book to read. It would be filled with all your adventures and special memories.

    Traveling around and seeing so much happening in the world around us is a wonderful experience. If we could all just travel a little more and share our experiences, we would all be better people and the world would be a better place.

    Reading is the ability to process text, understand its meaning and to integrate it with what the reader already knows. Of all the reading skills speed-reading is a necessary skill in the Internet age. We skim over articles, e-mails and WeChat to try to grasp key words and the essential meaning of a certain text. Surrounded with information from our electronic devices, it would be impossible to cope if we read word by word, line by line. But a new trend calls on people to unplug and enjoy reading slowly, listing benefits beyond the intelligent stimulation.

    A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. They sink into cozy chairs and read in silence for an hour. Unlike tradition book club, the point of the slow reading club isn't exchanging ideas about a certain book, but to get away from electronic devices and read in a quiet, relaxed environment. According to The Wall Street Journal, the Wellington book club is just one example of a movement started by book lovers who miss the old-fashioned way of reading before the Internet and smartphones.

    Slow readers, such as The Atlantic's Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to sympathize. Another study published last year in Science showed that reading novels helps people understand others' mental states and beliefs, a fundamental skill in building relationships.

    Yet technology has made us less attentive readers. Screens have changed our reading patterns from the top-to-right, left-to-right sequence to a wild skimming and skipping pattern as we hunt for important words and information. Reading text punctuated with links leads to weaker comprehension than reading plain text. The Internet may have made us stupider, says Patrick Kingsley from The Guardian. Because of the Internet, he says, we have become very good at collecting a wide range of interesting news, but we are also gradually forgetting how to sit back, reflect, and relate all these facts to each other.

    Slow reading means a return to an uninterrupted, straight pattern, in a quiet environment free of distractions. "Aim for 30 minutes a day," advises Kelly from The Atlantic. "You can squeeze in that half hour pretty easily if only during your free moments, you pick up a meaningful work of literature," Kelly said. "Reach for your e-reader, if you like. Kindles make books like War and Peace less heavy, not less substantive, and also ensure you'll never lose your place."
