    Why do men die earlier than women? The latest research makes it known that the
    reason could be that men’s hearts go into rapid decline when they reach middle age.
    The latest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
    “We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
    “Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
    What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
    “This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
    The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
    小题1:The text mainly talks about ________. 
    A．men’s heart cellsB．women’s ageing process
    C．the gender differenceD．hearts and long life
    小题2:According to the text, the UK scientists have known that ________. 
    A．women have more cells than men when they are born
    B．women can replace the cells that enable the heart to beat
    C．the female heart loses few of the cells with age
    D．women never lose their pumping power with age
    小题3:We can know from the passage that ________.
    A．the reason why ageing takes a greater loss on the male heart has been found out
    B．scientists are on the way to finding out why the male heart loses more of the cells
    C．the team has done something to prevent the male from suffering the greater loss
    D．women over 70 could lose more heart cells than those at the age of 20

    小题1:D
    小题2:C
    小题3:B

    Back those photos up
    The images were striking．Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions．
    If that doesn't move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos．
    Here is a brochure (手册) on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad．
    Scanning
    The first step for those old photos is to scan them and save them to a digital format (格式)．Most，printers come with scanners these days, so that's an easy but extremely time-consuming step．
    Storing the photos
    With your scans in place, import the photos into your computer, and back them up．
    You could make multiple copies of the disks and spread them to loved ones．Or you could choose external (外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer．
    Online backup
    If you need lots of space, look at a pure online backup service, Caronite．
    Caronite backs up 300 million files daily．Once you sign up, it starts to pick up everything you have on your hard drive．But photo collection on your computer's main hard drive charges for $ 59 a year．
    Cloud Storage
    For folks who don't need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft's SkyDrive let you store files online by yourself, share and instantly access them．All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive．But if you want more, you need to pay．
    Bottom Line
    The hard drive or flash drive is the cheapest and easiest．But drives can fail．Online services are more expensive, but more secure．With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are．
    小题1:What can we know from the passage?
    A．Scanning photos takes little time but costs a lot．
    B．The hard drive or flash drive is the cheapest and safest．
    C．Google Drive offers unlimited free photo storage on line．
    D．Caronite charges for backing up photos from hard drive．
    小题2:Which of the following allows storing files automatically?
    A．Caronite．B．Dropbox．C．SkyDrive．D．Flash drive.
    小题3:The main purpose of the passage is to ______．
    A．tell real stories about storage services
    B．introduce some of the storage services
    C．describe the functions of storage services
    D．argue about the advantage of storage services

    Earlier this year, the Environmental Protection Agency proposed a stricter nationwide health standard for smog-causing pollutants that would bring substantial benefits to millions of Americans. With a final rule expected by the end of this month, some opponents, mainly from industrial and oil-producing states, are pushing back. They say investments required to produce cleaner air are too expensive and not scientifically justified.
    Lisa Jackson, the E.P.A. administrator, needs to stick to her guns. This is only the first of several political tests to come this fall, as she also seeks to tighten rules governing individual pollutants like mercury and global warming gases like carbon dioxide.
    The health standard she is proposing covers ground-level ozone, commonly known as smog, which is formed when sunlight mixes with pollutants from factories, refineries, power plants and automobiles. Ozone is a major health threat, contributing to heart disease and various respiratory (呼吸道的) problems.
    Ms. Jackson’s proposal—to reduce the permitted level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billion—is sensible, no matter what industry’s defenders may claim. It had been recommended by the agency’s independent scientific panel but rejected by the Bush administration, which proposed a weaker standard.
    Industry will have to make investments in cleaner power plants, and new technologies may be required. As it is, about half the counties that monitor ozone levels are not yet in compliance with current standards, let alone the proposed standard.
    Fears about burdening industry raised by critics like George Voinovich, a Republican of Ohio, and Mary Landrieu, a Democrat of Louisiana, cannot be dismissed out of hand, especially in the middle of a recession (萧条). But the health benefits, E.P.A. says, far outweigh the costs, and the time frame for compliance (服从) is generous.
    小题1:Why are some people strongly against a stricter limitation of smog-caused pollutants?
    A．Because they have to live a poorer life.
    B．Because they think they have to spend more money.
    C．Because they hold different political view.
    D．Because they want to make more money.
    小题2: What does Ms Jackson propose to do?
    A．To reduce the permitted smog level as much as possible.
    B．To raise the permitted smog level as much as possible.
    C．To keep the permitted smog level from 60 to 70 to 75 parts per billion.
    D．To lower the permitted smog level from 75 to 60 to 70 parts per billion.
    小题3:What is the attitude of the author to the smog-controlling issue?
    A．Objective.B．Subjective.C．Critical.D．Unknown.
    小题4:Which of the following can serve as the best title of the whole passage?
    A．Cleaner power plant on the way.
    B．Say no to smog pollutants.
    C．Lower smog pollutant, better our life.
    D．Debate on smog pollutants.

    EAT YOUR VEGETABLES.Wash your hands. Always say  “please” and “thank you”. We are full of advice for our children, but when it comes to money, we often have little to say. As a result, our children may grow up with clean hands and good manners, but without any idea how tomanage their money.
    　　Here are some basics that will help guide them their entire lives:
    　　Show them the future. If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month, by the time she’s 65,she would have $980,983!
    　　Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history, but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card, you can easily end up paying two or three times what you would have paid if you used cash.
    　　Teach patience. Suppose your child wants a new bicycle that costs $150.Rather than paying the cash, give him some regular pocket money and explain that by putting aside,say,$15 each week, he will be able to buy it for himself in only ten weeks.
    　　Provide incentive. Tell your children the importance of saving. “For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot,” says Cathy Pareto, expert in money planning.
    　　Explain your values. Values and money are deeply intertwined, says Eilleen Gallo,co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don’t want to buy it.“You might say, ‘I’d rather save that money for your  education,’” advises Gallo. Every time you spend or don’t spend money, you have a chance to share your values.
    小题1:The writer gives some basics to help________ in a proper way.
    A．parents teach their children how to deal with money
    B．children follow their parents’ instructions
    C．children manage their money
    D．parents save their money
    小题2:The writer thinks that, if a child wants to buy something, his parents should________.      .
    A．give him some regular pocket money
    B．encourage him to put money away for it
    C．explain to him the importance of investment
    D．tell him to save some money by using a credit card
    小题3:The underlined word “incentive” in paragraph 6 means_________.       .
    A．honorB．praiseC．excitementD．encouragement
    小题4:What leads the writer to write this article?_________
    A．Parents want to know how to educate their children.
    B．He wants to share his good ideas about money matters.
    C．He thinks money management the most important for children.
    D．Parents care Little about their children’s management of money.

    If you get a cellphone call, your sleeve(袖子) will soon be able to answer it. If you want to know how far you’ve run, your trousers will be able to tell you. Can’t decide what to wear? Wish your clothes were smart enough to decide for you? A new computer science technology may be able to help your clothing to do just that.
    Mark Jones, a computer scientist, says, "We view electronic textiles (电子纺织品) as, sort of, where computing meets the fabric (编织品)."
    This high-tech marriage is bringing up the wearable computers, like trousers that can interpret movement and let a computer know your every move.
    A loom (织布机) helps make the wires and fabric together. Then special equipment in the fabric can measure the speed. Signals are then sent from the trousers to a computer to show the process.
    Tom Martin also says, "E-textiles are a way for us to build wearable computers that look like normal clothing and can fit in fully with the environment."
    Researchers also hope wearable computers will help save lives. "We will be able to tell what activity a person is doing. That sort of information is highly valuable when we’re trying to monitor someone with a long-term illness such as heart disease," Jones says. Monitoring your every step is something that clever clothing can do a little easier. Researchers plan on developing more smart clothes to integrate computers into shirts, hats and gloves.
    小题1:What does the underlined word "marriage" refer to in the passage?
    A．The special equipment in the fabric used to measure the speed of our movement.
    B．The unity（结合）of fabric and computing materials to make smart clothes.
    C．Wearable computers which fit in with the environment.
    D．The influence of electronics and computer science technology.
    小题2:How will smart clothes be able to know the wearer’s every movement?
    A．There are the wires and fabric together.
    B．There are signals in the smart clothes.
    C．The computer built into them will control their every movement.
    D．The clothing will have special equipment fixed into the fabric.
    小题3:The reason that people need smart clothes is that __________.
    A．people are too lazy to decide what to wear
    B．scientists want to prove their intelligence
    C．smart clothes can provide information about the wearer’s health
    D．smart clothes are as cheap as normal clothes
    小题4:What is the best title for the passage?
    A．Connecting Clothes with High Technology
    B．New Ways to Discover Illnesses Early
    C．How to Use a Computer
    D．Smart Clothes and Exercise

    Scientists are making new studies of color and its effects on our health. They have known for a long time that the color of a room or the color of the light in it can affect our feelings and emotions. Many prisons and hospitals have at least one room that is painted pink. Officials have found that light and color can produce physical changes in our bodies.
    Professor Falfan worked with a group of 9 disabled children at school in Albert. Two of the children were blind. The other seven had normal sight. The scientists changed the color of the school room, then looked for changes in blood pressure, heart beat and breathing rate. The effects of color changes were the same for the blind children as for those with normal sight. Their blood pressure dropped from about 120 to 100. Similar changes were reported in heart-beat and the breathing. The children also were calmer and less excited. Then the colors of the room were returned to orange and white. Blood pressure, heart-beat and breathing rate went up and the children became excited again.
    Professor Falfan said different colors produce different levels of light energy. He said the differences seem to affect chemicals in the brain that carry messages from nerve to nerve and from nerve to muscle.
    小题1:Light and color can affect________.
    A．only one’s feelings and emotions
    B．one’s energy
    C．one’s mental changes
    D．one’s heart-beat, brain activities, blood pressure, feelings and emotions
    小题2:The color of pink had a calming effect, that is to say, the color affects __________.
    A．the chemicals in the brainB．the eyes
    C．the skinD．the muscle
    小题3:According to the text, orange and white are colors which can make people ________.
    A．calm B．activeC．sickD．blind
    小题4:The colors in the school room mentioned in the passage were changed from _________.
    A．orange to whiteB．orange and white to dark blue
    C．orange and white to pink or some other colorsD．gray to more colors
    小题5:After reading the passage we can conclude that ________.
    A．blind people can be affected by colors, too
    B．one’s heart will beat fast in a colorful room than in a white room
    C．the chemicals in the brain change with feelings and emotions
    D．if one’s blood pressure drops, his breathing will get slower and slower

    Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
    There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).
    Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
    Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.
