    Can exercise during childhood protect you against memory loss many decades later?Exercise early in life seems to have lifelong benefits for the brain,in rats at least.

     “This is an animal study,but it shows that physical activity at a young age is very important—not just for physical development,but for the whole lifelong track of cognitive(认知的)development during ageing,”says Martin Wojtowicz of the University of Toronto,Canada.“In humans,it may delay the appearance of Alzheimer's symptoms(阿茨海默氏症),possibly to the point of preventing them.”

    Wojtowicz's team divided 80 young male rats into two equal groups,and placed running wheels in the cages of one group for a period of six weeks.Around four months later—when the rats had reached middle age—the team taught all the rats to connect an electric shock with being in a specific.When placed in the box,they froze with fear.

    Two weeks later,the team tested the rats in three situations: exactly the same box in the same room,the same box with the room arranged differently,and a completely different box in a different room.

    The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations,suggesting they couldn't remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

    "The results suggest the amount of physical activity when we're young,at least for rats,has influence on brain and cognitive health—in the form of better memories—when we're older,"says Arthur Kramer of Northeastern University in Boston,who has found that,in humans,exercise promotes the growth of new brain cells.

(1)、The study shows that          
A、physical activity is important for physical health B、using the running wheels is of benefit to the rats' growth C、physical activity can prevent human's Alzheimer's symptoms D、the more exercise a rat has when young,the better memory it will possess when older
(2)、How are Paragraph 3 and 4 mainly developed?
A、By analyzing causes. B、By giving an example. C、By describing the process. D、By showing differences.
(3)、What does the underlined word "it" in Paragraph 2 refer to?
A、Exercise. B、Development. C、Benefit. D、Study.
(4)、What is the author's attitude towards the animal study?
A、Negative. B、Objective. C、Critical. D、Doubtful.

    The year 2018 will mark the 100th anniversary of the deadliest influenza outbreak in history. It is estimated that the influenza pandemic(瘟疫) of 1918 killed more than 50 million people around the world. Other estimates go much higher. Because of a lack of medical record—keeping, we may never know the exact number.

    The influenza was a fast killer. Some victims died within hours of their first symptoms. Others died after a few days. “Their lungs filled with liquid and they choked to death. ”The 1918 flu pandemic was also different from other outbreaks. It struck many young, healthy people. Viruses usually affect sick or old people.

    Although modem medicine effectively controls many diseases, influenza remains difficult to protect against, The World Health Organization estimates that every year influenza kills 250, 000 to 500, 000 people around the world. Each year, medical scientists develop flu vaccines(疫苗) which offer immunity(免疫)from some influenza viruses. But they can only guess which form of the virus will spread.

    Health officials remain concerned about another flu pandemic. New forms of the flu virus appear regularly. One example was the “swine flu”or H1N1outbreak in 2009. Anthony Fauci, Director of the National Institute of Infectious diseases in the United States says that virus caused a true pandemic.

    To stop the next pandemic, scientists are now researching how to create a universal influenza vaccine. In October 2017, Vanderbilt University Medical Center in the U. S. announced the Universal Influenza Vaccine Initiative. The university said researchers are leading an international effort to develop a universal influenza vaccine that will protect everyone against all forms of the flu anywhere in the world. The university added that researchers will begin tests in early 2018, the Human Vaccines Project, a public—private partnership, is funding the project. However, until a universal influenza vaccine is available, today's seasonal flu vaccine remains important.

    There is little rain in desert. Because deserts are so dry, they have no “quilt” to help stop the soil from going away. As a result, they may get very hot during the day with the sun shining, but don't hold the heat overnight. Many deserts can quickly get cold once the sun goes down. Some deserts can reach temperatures of over 100 degrees F during the day and then drop below freezing (32 degrees F) during the night.

    The largest hot and dry desert in the world is the Sahara Desert in Northern Africa. The Sahara is a sandy desert with great sand hills. It covers over 3 million square miles of Africa. Other large deserts include the Arabian Desert in the Middle East, the Gobi Desert in Northern China and Mongolia, and Kalahari Desert in Africa.

    Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat. Other animals keep water that they can use later. The camel stores up fat in its hump while other animals keep something they need in their tails.

    Only certain types of plants can live in the terrible environment of the desert. You won't see a lot of tall trees in the desert. Most plants have a way to keep water in their leaves, or trunks so they can live a long time without water.

    Now deserts cover around 20% of the world's land, but they are growing. This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it?

    Outside, it's a cold winter's day. Inside a large shopping center, people are hanging around. But then, without warning, a pop song starts to play loudly. A teenager boy walks lazily to the center of the open space, and dances crazily to the music. He's joined by two of his friends, then some of the old people. Within the space of a few seconds, more than sixty people are dancing to the music - all in time and all in step. At first, onlookers are baffled, then they start smiling and clapping. They now know what they're seeing: a flash mob (快闪).

    According to Wikipedia, the term "flash mob" was created by Bill Wasik, an editor at Harper's Magazine, in 2003. Within a year, the phrase had entered the Concise Oxford English Dictionary. Since then, hundreds - possibly thousands - of flash mobs have been carried out around the world, in almost every kind of public space imaginable!

    Each flash mob has its own style, but most flash mobs follow a similar formula (方案). Often, the organizers search for willing participants using social media. Instructions and dance moves are given through email or video download. There are usually several rehearsals (排练) before the big day.

    While it's happening, a few lucky passers-by watch it live. Most people who watch it, however, will see it later online. Some of the most popular flash mobs on YouTube have been watched more than 10million times. A famous example is MP3Experiment Eight, a flash mob that took place in New York City in July 2011 with over 3,500 participants. This event differed from normal flash mobs in that much of it was completely silent - and there were no rehearsals.

    Flash mobs provide the participants, onlookers and online viewers with a lot of enjoyment and pleasure. For this reason alone, they're a modern, popular art form that should be celebrated.
