    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

    So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.

    It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

    The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

    "This explains most of the previous failures of drug trials against rhinovirus," study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

    Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

    With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

(1)、What does the author think of popular remedies for a common cold?
A、They are quite effective. B、They are slightly helpful. C、They actually have no effect. D、They still need to be improved.
(2)、How do antiviral drugs work?
A、By breaking up cold viruses directly. B、By changing the surface structures of the cold viruses. C、By preventing colds from developing into serious diseases. D、By absorbing different kinds of cold viruses at the same time.
(3)、What can we infer from the passage?
A、The surface of cold viruses looks quite similar. B、Scientists have already found a cure for the common cold. C、Scientists were not aware of the existence of rhinovirus C until recently. D、Knowing the structure of cold viruses is the key to developing an effective cure.
(4)、What is the best title for this passage?
A、Drugs against cold viruses B、Helpful home remedies C、No current cure for common cold D、Research on cold viruses

    Our news is constantly filled with the reality of death and dying. And each of us, if we live long enough, experiences the loss of persons we loved. Children ages eight through ten were asked what they thought about death,and these are some of their answers:

    “When you die,God takes care of you like your mother did. When you were alive,only God doesn't yell at you all the time.''(Beth,9)

    “When you die,they bury you in the ground and your soul goes to heaven,but your body can't go to heaven because it's too crowded there already.” (Jimmy, 8)

    “Only the good people go to heaven. The other people go where it's hot all the time like in Florida. ” (Judy,9)

    “Doctors help you so you won't die until you pay their bills.”(Stephanie,9)

    I've observed that the loss of a loved one can be one of the most difficult things we humans can face. I've known friends of sick and dying people to sit by a bedside or in a hospital room for hours,even days, at a time. I've seen food in homes of people who are dying overflow from kitchen to dining room—food brought by comforting friends from church and con cerned neighbours. And I've observed friends just listen for as long as it takes.

    When U.S. Congressman Sam Rayburn (1882—1961) discovered that he was ill,he announced to the House of Representatives he was going home to Texas for medical tests. Some wondered why he did not stay in Washington where there were excellent medical facilities. His answer was a beautiful tribute (颂词) to friendship:"Bonham is a place where people know it when you're sick,and where they care when you die. ”

    No one wants to go through difficult times alone. So Rayburn traded the best of medical technology for the closeness of loving friends. He knew that good friends are good medicine. Often the best.

    In beautiful rural Montana lies the town of Livingston. Around half the students in the Livingston School District qualify for free or reduced-price lunches, according to local educator Rachael Jones, known as "Farmer Jones". She is the director of the Livingston Farm to School program, which uses the district's two greenhouses and four gardens to grow food that supplements school meals while offering kids hands-on lessons. Jones said, "In many places around the country, if you can't pay for your school meal, you don't eat. Well, here, we don't turn anyone away."

    The town's school district and community members started the program eight years ago. It's part of the National Farm to School Network, which aims to increase access to local food and nutrition education across the country. Jones, who attended public school in Livingston as a kid, has headed up the local program since 2014. Farm to School enriches curriculums in all of the schools through garden lessons, cafeteria and kitchen lessons, and classroom lessons.

    Research has shown that healthy school meals can enhance academic performance, including improved test scores. Though the Farm to School program is not aimed solely at lower-income students, Jones said, "Such kids are more likely to eat lunch provided by the school. Eventually she wants to get healthy, affordable meals on the plate of every child in Livingston.

    It is important for kids to understand where their food comes from. That's a life changing experience for them. Jones said," When I grew up a big force in my life was my grandma Ethel. She taught me from a really early age the value of growing my own food. I worked in her gardens with her and somehow, through all of those experiences —eating her tomatoes and canning pickles with her —it really built up my trust and knowledge in food systems. I'm so thankful for her!"

    Over the past century, an alarming number of animals have become endangered or even extinct. Below are some animals whose numbers have been rapidly dropping in recent years.

    Panda Bear

    One of the biggest reasons contributing to the decline in the panda species is the destruction of its natural habitat. Farmers in China have gradually been claiming more and more of the land. As a result, pandas are forced to move away to places where it is hard to find bamboo for food.

    Green Turtle

    The green sea turtle species has survived for several millions of years, so you might wonder why it's only becoming endangered now. A major cause is the change in climate and temperature, which both affect the hatching rates of turtle eggs. Climate changes also cause violent weather and rising water levels to flood areas where turtles usually go to lay their eggs. Apart from this, oil spills and other poisonous pollution, as well as increased fishing activities can cause sickness, or even death to the green turtles.

    Cheetah

    Cheetahs are famous for being the fastest animal on land but even they can't run from some of the larger threats that have harmed them. Like the panda bears, cheetahs have gradually been losing their natural homes due to humans claiming land and developing in those areas. To make matters even worse, smaller animals move away when these areas are occupied, which means that the cheetah has less food! Don't forget that other large animals, such as lions, are also fighting for any food that they can find, so occasionally young cheetahs end up as prey too.

    Indian Elephant

    Elephants are extremely intelligent animals and also the largest mammals that live on land. Sadly, in Asia many elephants were killed so that people could remove their tusks to use as decorative objects. While this practice has been banned now, some people still illegally continue. Forests in India have also been steadily destroyed and elephants are sometimes killed when they end up on human territory.

    A popular TV host has reportedly invested about US $740,000 in a project to research, preserve and promote the Hunan provincial dialect (方言). Chinese TV presenters are required to speak Mandarin, or Putonghua, as part of their work, but should dialects be allowed on air?

    Bcnu (China): TV and radio stations have the right to decide whether dialects or Mandarin will be used in their programs. The popularity of some dialects in some areas will not challenge the leading role of Mandarin in the whole country.

    Rick N (US): TV and radio broadcasters should take the lead in popularizing Mandarin. To require hosts to speak standard Mandarin is not to oppress (压制) dialects, but it only aims to restrict irresponsible use of language. I think it is unprofessional for some hosts particularly to imitate the pronunciation of dialects.

    Cooper (UK): Dialects are an important part of local culture and now many kids even don't know how to speak their dialects because of the main use of Mandarin around them. It would be a pity if future generations were unable to understand the local dialects. It would be a terrible break in cultural traditions.

    Steve (France): To attract viewers or make more money, some hosts casually use dialects. Demanding TV and radio programs use Mandarin is a move to limit strange and irresponsible use of language, whether it is Mandarin or other dialects. In this way, the decision is also a form of protection for dialects. Hearing standard Mandarin on TV and radio programs is also a basic right of audiences around the country.

In the 1990s, a psychologist named Martin Seligman led the positive psychology movement, which placed the study of human happiness squarely at the center of psychology research and theory.

Since then, thousands of studies and hundreds of books have been published with the goal of increasing well-being and helping people lead more satisfying lives. But for over 40 years, self-reported measures of happiness have stayed stagnant (停滞的). Such efforts to improve happiness have been an ineffective attempt to swim against the tide, as we may actually be programmed to be dissatisfied most of the time. Why aren't we happier?

Part of the problem is that happiness isn't just one thing. Jennifer Hecht, a philosopher who studies the history of happiness, proposes that we all experience different types of happiness, which are not necessarily complementary Some types of happiness may even conflict with one another. In other words, having too much of one type of happiness may weaken our ability to have enough of the others. For example, a satisfying life is built on a successful career and a good marriage. It takes a lot of work and often requires cutting back on many of life's pleasures. That means we can't spend one pleasant lazy day after another in the company of good friends.

This difficult situation becomes more confused by the way our brains process the experience of happiness. A lot of evidence shows that most of the people possess something called the optimistic bias. They tend to think that their future will be better than the present.

Cognitive psychologists have also identified something called the Pollyanna Principle. It means that people process, rehearse and remember pleasant information more than unpleasant information. Why the good old days seem so good is because we focus on the pleasant stuff and tend to forget the unpleasantness. And if our past is great and our future can be even better, then we can work our way out of the unpleasant present.

Dissatisfaction with the present and dreams of the future are what keep us motivated. In fact, endless happiness would completely destroy our will. Among our earliest ancestors, those who were perfectly content may have been left in the dust.

Recognizing that happiness exists may help us appreciate it more when it arrives. Furthermore, understanding that it's impossible to have happiness in all aspects of life can help us enjoy the happiness that has touched us. Recognizing that no one "has it all" can cut down on the one thing that psychologists know prevents happiness: envy.
