As we all know, friendship is of great importance in our daily life. A friend can give us help and share our difficulties and happiness. But how to make friends is still difficult to some of us. {#blank#}1{#/blank#}

    1). Be friendly to others. {#blank#}2{#/blank#} You should try to make a stranger feel at home wherever he happens to be. Think more of others than of yourself and never judge a person by his appearance and clothes.

    2). Be reliable. If you and your friend agree to meet somewhere, don't be late. If you're not going to make it on time or make it at all, call them as soon as you realize it. {#blank#}3{#/blank#} Be someone that people know they can depend on.

    3). {#blank#}4{#/blank#} Listen carefully to what people say, remember important details about them （their names, their likes and dislikes）, ask questions about their interests, and just take the time to learn more about them.

4). Encourage your friends: A true friend always gives courage to his friends. {#blank#}5{#/blank#} Never make fun of or laugh at your friends in front of others. You should come to support them.

    A study published Monday found that people who sleep less tend to be fat，and experts said it's time to find out if more sleep will fight fatness.

    “We've put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

    Monday's study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

    “Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

    “Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

    “Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

    “We caution that this study does not set up a cause­and­effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

    The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

    In an interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

    “Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“leading to a variety of health problems.”

    Traveling alone gives you the freedom to create your own schedule and do as you please. {#blank#}1{#/blank#} For example, a travel partner can provide practical support and celebrate in the rewards of first-hand experience with unfamiliar locations and cultures. Here are several steps to find a travel partner who will improve your journey. {#blank#}2{#/blank#} Traveling should be fun. When you are on a trip, you will want to do lots of activities that you enjoy. Preferably, your companion will want to do the same things as you.

    Discuss financial plans. Before you travel, you should plan a budget. {#blank#}3{#/blank#} You don't want to be planning an expensive getaway when your friend is looking for budget travel.

    Have an honest conversation. If you are thinking about traveling with a companion, take some time to have an open discussion. Schedule a time to sit down and talk. Try saying, "I know we've talked about the idea of traveling through Europe together. Let's have a coffee this week and actually talk that through." {#blank#}4{#/blank#} You should also talk about your travel style.

    Find someone who is flexible. Choose a travel partner who can adjust. {#blank#}5{#/blank#}Maybe it will rain on the day you planned to visit the Grand Canyon. Or you might not be able to get reservations at that French restaurant you've been dying to try.

A. Look for someone with common interests.

B. You should discuss your goals for the trip.

C. Travel with a friend who is pretty easygoing.

D. But traveling with a partner has its benefits, too.

G. No matter how carefully you plan your trip, it is likely that something will go wrong.

    Asthma(哮喘) is a long-lasting breathing disease that affects millions of Americans, many of whom are children. People who get asthma will suffer from lack of breath, difficulty in breathing or coughing--which are caused by the tightening of the muscles in airways. Untreated asthma can lead to poor lung function and death, but asthma can also be effectively controlled with proper treatments.

    Research is discovering genes that contribute to the development of asthma. This development has pointed researchers to the role of indoor and outdoor pollution as environmental factors that contribute to the increased occurrence of asthma.

    The Indoor Pollution

    Indoor pollution has increased with the developments in building materials and in heating and air conditioning systems. In addition to poisonous gases that come from paint, other materials like dust and perfumes used in household products such as washing powder are recycled continuously through the house, winter and summer.

Unlike the days before central heating or before whole-house air conditioning, these materials and chemicals cannot get out of modern homes. Most  often, they cause breathing  problems in the members of the family with the least-developed autoimmune(自身免疫的) systems. Proper venting (通风) and use of environmentally-friendly building materials and carpeting can help reduce the presence of these chemicals.

    The Outdoor pollution

    Researchers have also established outdoor pollution's role as a probable cause of asthma. Asthma has been proven to result from some fuel products. Smog and the small matters carried by it have been recognized as a factor which leads to asthma since the 19th century when London saw more and more diseases in the industrial population. Industrial pollutants and other chemicals which are produced in water treatment and open treated water like that found in the swimming pools also contribute to increased cases of asthma as well as other illnesses.

    Those most affected by the increase of industrial and environmental pollution are children. Although much has been done to control the levels of pollution in the US, there still remains much to do as it is a worldwide phenomenon. Until an international effort can be made to limit carbon emissions, the occurrence of environmental asthma will probably continue to increase.

    Directions: Read the following passage. Fill in each blank with a proper sentence given in the box.

    Each sentence can be used only once. Note that there are two more sentences than you need.

    Are Your Clothes Causing Pollution?

    Very small pieces of plastic, called microfibers, are polluting rivers and oceans. {#blank#}1{#/blank#} Clothes worn for outdoor activities and exercise are often made of artificial material, which is useful in keeping warm. But they contain very small plastic fibers, which may also be harming the environment when you wash them. When people wash these clothes, very small pieces go down the drain with the wash water.

    Studies on microfibers in the environment

    Pollution caused by plastic is not new, but recent studies have shown the effect of microfibers in the environment. Studies show very small microfibers are ending up in our waters, which may come from waste water treatment factories. A 2015 study found them in fish from California.

    Microfibers, effect on food supplies

    Beyond the waterways, the researchers say microfibers may end up in soil and agricultural lands. {#blank#}2{#/blank#} This means there is much to be learned about microfibers and the environment. Some studies have shown that microfibers end up inside sea animals, like oysters. {#blank#}3{#/blank#} Researchers say that the fibers tend not to move into the tissue of the fish, but it needs more study.

    Steps to save or keep microfibers from the environment

    Until more information becomes known, there are steps to take to reduce the amount of microfibers in the environment. People should use less of the artificial materials. If we already have those in our lives and we're using them, an important step would be washing them less. {#blank#}4{#/blank#} A bag is being designed in which to wash these clothes. It traps the microfibers in the bag and it may be available for purchase soon.

A. New technology may also help.

B. So if these microfiber s have been found in fish and seafood, are they safe to eat?

C. They can also move around the atmosphere.

D. Studies are conducted on how much of the microfibers is released

E. The source of these microfibers may surprise you: your clothes.

F. Washing machines keep microfibers from escaping with w ash water.

    Pretending you're someone else can make you creative

    One great irony(讽刺) about our collective fascination with creativity is that we tend to frame it in uncreative ways. That is to say, most of us marry creativity to our concept of self: We are either "creative" people or we aren't, without much of a middle ground.

    Pillay, a tech businessman and Harvard professor has spent a good part of his career destroying these ideas. Pillay believes that the key to unlocking your creative potential is to dismiss the conventional advice that urges you to "believe in yourself". In fact, you should do the exact opposite: believe you are someone else.

    In a recent column for Harvard Business Review, Pillay pointed to a 2016 study showing the impact of stereotypes(刻板印象)on one's behavior. The authors, education psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into three categories, instructing the members of one group to think of themselves as "eccentric(古怪的) poets" and the members of another to imagine they were "rigid librarians" (people in the third category, the control group, were left alone for this part). The researchers then presented participants with 10 ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. Those who were asked to imagine themselves as "eccentric poets" came up with the widest range of ideas for the objects, while those in the "rigid librarian" group had the fewest. Meanwhile, the researchers found only small differences in students' creativity levels across academic majors—in fact, the physics majors inhabiting(寄生) the personas(伪装的外表) of "eccentric poets" came up with more ideas than the art majors did.

    These results, write Dumas and Dunbar, suggest that creativity is not an individual quality, but a "malleable(可塑的) product of context and perspective." Everyone can be creative, as long as they feel like creative people.

    Pillay's work takes this a step further: He argues that identifying yourself with creativity is less powerful than the creative act of imagining you're somebody else. This exercise, which he calls "psychological halloweenism", refers to the conscious action of inhabiting another persona—an inner costuming of the self. It works because it is an act of "conscious unfocus", a way of positively stimulating the default mode(默认模式) network, a collection of brain regions that spring into action when you're not focused on a specific task or thought.

    Most of us spend too much time worrying about two things: How successful/unsuccessful we are, and how little we're focusing on the task at hand. The former feeds the latter—an unfocused person is an unsuccessful one, we believe. Thus, we force ourselves into quiet areas, buy noise canceling headphones, and hate ourselves for taking breaks.

    What makes Pillay's argument stand out is its healthy, forgiving realism: According to him, most people spend nearly half of their days in a state of "unfocus". This doesn't make us lazy people—it makes us human. The idea behind psychological halloweenism is: What if we stopped judging ourselves for our mental down time, and instead started using it? Putting this new idea on daydreaming means addressing two problems at once: You're making yourself more creative, and you're giving yourself permission to do something you'd otherwise feel guilty about. Imagining yourself in a new situation, or an entirely new identity, never felt so productive.
