The expression “a thirst for knowledge" may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world.
About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria.
The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles (微粒) of silver. The pages can be used as filters（过滤器）to remove harmful microorganisms (微生物) that can pollute drinking water. The filter kills the organisms that pass through it.
Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned.
Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages.
"The idea of classic texts—that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through that part," she says.
Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful.

As a health editor, I spend the majority of my day poring over content related to health. At HuffPost, we're lucky to talk to experts on a daily basis about how to live our best lives. It’s clear that life would be healthier if we would just do the following things. Sure, some of these are easier said than done.
1.Have a bedtime.
Sleep is considered the third pillar(支柱) of health, and for good reason. Research is only making it increasingly clear that not getting enough of the stuff can have serious health effects. Meanwhile, getting enough sleep is good for everything ranging from weight, to mood, to even the immune system. One of the simplest things you can do to ensure you get enough sleep each night is to set a bedtime. Forgive yourself if you can't meet it every night, but make a point to try to stick to it.
2. Cultivate your emotional intelligence
To have emotional intelligence means to be "confident, good at working towards your goals and adaptable. You recover quickly from stress." psychologist Daniel Goleman previously told HuffPost. It's made up of five parts: social skills, empathy, motivation, self-awareness and self-regulation. And fortunately, these are all traits you can cultivate. Be curious about things beyond yourself. Know what you're good at and where you can stand to improve. Try to improve your ability to pay attention.
3.
This is something I'm still working on. I'm an objectively fast person -- fast at walking, fast at eating, fast at talking. This also makes me very impatient, and also sometimes very unobservant -- stopping to smell the roses has never been my strong suit. But slowing down to appreciate life and all its little moments builds gratitude -- and that's a very healthy thing.
4. Find an exercise you actually enjoy
It's not exactly a secret how much I opposite-of-like running. I'll still do it, because of health, but there are certainly other ways I'd rather get my fitness in. And that's completely OK. Research has even shown that whether we think of fitness as "fun" or "exercise" affects how much we end up eating. For me, exercise is a pill best swallowed as volleyball. For you, it may be dancing, or swimming, or riding your bike. Don't think that just because you don't like "conventional" exercise -- running, going to the gym, etc. -- you're "bad at exercise." No such thing!Which of the following has something to do with the immune system?
| A．exercise | B．sleep |
| C．emotional intelligence | D．mood |
What can we infer from the passage?
| A．You should set a bedtime and stick to it no matter what happened. |
| B．Paying attention is not as important as other abilities for emotional intelligence. |
| C．The writer is no longer a fast person. |
| D．The exercise the writer likes most is volleyball. |
Emotional intelligence includes the following except______.
| A．confidence | B．motivation |
| C．stress | D．self-awareness |
The best title for the third tip is___________.
| A．Feel gratitude to life |
| B．Stop to smell the roses |
| C．Lead a simple life |
| D．Take a time to appreciate your life |
Most city parks are places where you can escape from big, ugly structures of metal and stone. The Manhattan High Line is different. Raised 25 feet above the ground, this large metal structure once supported a rail line. The line opened in 1934 to bring trains directly into factories. It was hardly used after the 1960s, and much of it was torn down. However, one part remained in a region of Manhattan called Chelsea. Chelsea was becoming high-class as restaurants, art galleries and apartments were built, but the ugly railway structure remained as a dead weight. Everyone knew that at some time, it would have to be removed.
But the High Line was not destroyed. In fact, now the old rail line serves as one of the most peaceful places in the city. It holds an elevated(高架的) park, with beautiful gardens and great views of the city. The idea to turn the rail line into a park came from Joshua David and Robert Hammond. In 1999, they attended a meeting to decide how to deal with the High Line. David and Hammond were the only people at the meeting interested in saving the historical structure. Later on, when they asked railway officials to take them up to look at the High Line, they saw a mile and a half of wild flowers growing in the middle of the city, and they realized that the High Line had potential(潜力) to become a park. There was growing interest in improving city centers, and so the project quickly developed and money for construction was easily collected.
The first section of the High Line opened in 2009 and immediately became popular with tourists and locals alike. Each part of the park has a different atmosphere. Some areas are like balconies(阳台) with wonderful city views. Where the rail line goes between buildings, trees are thickly planted. Other sections have wide lawns(草坪) and walkways planted with wild flowers. Only the final section remains the way it has been for the last fifty years.What is the text mainly about？
| A．Protection of cultural relics. |
| B．An unlikely place for a park. |
| C．Improving city transport. |
| D．Closing a train line. |
The underlined part “a dead weight” (Paragraph 1) means__________.
| A．something with potential to be better |
| B．something with historical interest |
| C．something useless which slows progress |
| D．something which is a danger to people |
Why did David and Hammond originally want to save the High Line?
| A．They thought it had historical value. |
| B．They thought it would make a good park. |
| C．They wanted to reopen the train line. |
| D．They were interested in improving the city. |
Why were people easily persuaded by David and Hammond’s idea?
| A．They wanted to see the wild flowers too. |
| B．They realized the High Line was historically important. |
| C．They wanted to make cities nicer places. |
| D．They knew the project would bring in much money. |
What can we learn about the High Line from the text?
| A．It was designed by David and Hammond. |
| B．It began to be popular in the 1960s. |

One day when I left a bookstore and walked on the street, I saw a woman standing outside the post office. She looked pale and worried. I stopped and asked if she needed help.

Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.
After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity(肥胖症) — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.In what way are the French different from Americans according to Dr. Joseph Mercola?
| A．They go shopping at supermarkets more frequently. |
| B．They squeeze eating between the other daily activities. |
| C．They regard eating as a key part of their lifestyles. |
| D．They usually eat too much canned and frozen food. |
This text is mainly the relationship between _________.
| A．Americans and the French |
| B．life style and obesity |
| C．children and adults |
| D．fast food and overweight |
The text is mainly developed __________.

| B．Most of French children suffer from obesity. |
| C．Recent life style changes may be affecting French eating habits. |
