Half of US mothers are not getting enough sleep and they believe getting more rest would make them better parents, according to a US study. A nationwide survey of 500 mothers by research firm Braun Research found 54 percent of respondents said they were not getting enough sleep. Full-time working mothers were suffering the most with 59 percent saying they were not getting enough sleep. Half of the working mothers said they were getting six or fewer hours sleep a night. Stay-at-home moms felt better with 48 percent saying they were sleep deficient. The survey found 52 percent of America's mothers believed that getting more sleep would make them better parents and 65 percent said it would make them happier.

       But even when mothers do get into bed, many lie awake at night with 36 percent thinking about the next day's tasks, 25 percent stressing about the family's finances and 24 percent worrying about family issues. "Consistently not getting enough sleep and lying awake at night worrying about day-to-day challenges could be a sign of insomnia," said sleep specialist Suzanne Griffin, a clinical doctor from Georgetown University Hospital in Washington. But the survey found although sleep problems were among mothers, four out of five had not spoken to their doctor about it and 82 percent never considered using sleeping pills.

       Griffin suggested that mothers stick to a sleep schedule, avoid alcohol and caffeinated drinks late in the afternoon and before bedtime, and create a sleep environment that is cool, quiet, dark and comfortable.

1．Which of the following is related to the underlined word in the passage?        .

       A．bad health               B．illness              C．good sleep              D．bad sleep

2．According to the US study, the following statements are true except that        .

Electric cars will not be really much cleaner than autos powered by mineral fuels until they rely less on electricity produced from usual coal-fired power plants.
“For electric vehicles to become a major green alternative, the power fuel has to move away from
coal, or cleaner coal technologies have to be developed,” said Jared Cohon, the chairman of a National
Research Council report released on Monday. About half of US power is produced by
burning coal, which gives off many times more of traditional pollutants than natural gas, and about
twice as much of the main greenhouse gas carbon dioxide. Nuclear and renewable power have to
generate a larger portion of US power for electric cars to become much greener compared to
gasoline-powered cars, Cohan, who is president of Carnegie Mellon University, said in an interview.
Advances in coal burning, like capturing carbon at power plants for permanent burial underground,
could also help electric cars become a cleaner alternative to vehicles powered by fossil fuels, he said.
Pollution from energy sources did $120 billion worth of damage to human health, agriculture and
recreation in 2008, and electricity was responsible for more than half of the damage, said the NRC
report.
Electric cars have their benefits such as reducing imports of foreign oil. But they also have hidden
costs. Materials in electric car batteries are hard to produce, which adds to the energy it takes to make
them. In fact, the health and environmental costs of making electric cars can be 20 percent greater
than usual cars, the report said.
The report estimated that electric cars could still cost more than gas-powered cars to operate and
manufacture in 2030 unless US power production becomes cleaner.
1. Why are electric cars not clean enough?
A. Because they run too slowly              B. Because they are too expensive
C. Because they rely on coal-fired power.      D. Because they give off more carbon dioxide.
2. We can infer from the passage that ______.
A. electric cars will soon take the place of gas-powered cars
B. no one holds hope for electric cars at present
C. electric cars waste more energy than before
D. some people believe that electric cars are cleaner
3. The underlined word “them” refers to “______”.
A. electric cars     B. batteries       C. producers        D. materials
4. Which of the following is NOT mentioned as a way to make electric cars cleaner?
A. Developing cleaner coal technologies.        B. Making electric cars run faster.
C. Generating more unclear power.             D. Making advances in coal burning.

We’ve reached a strange—some would say unusual—point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It’s the good life that’s more likely to kill us these days.
Worse, nearly l8 million children under the age of five around the world are estimated to be overweight. What’s going on?
We really don’t have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through—up to a point.
In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world’s most body-conscious country.
We know what we should be doing to lose weight—but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower.
Others blame good food. They say: it’s just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American-style fast food.
Some also blame their parents—their genes. But unfortunately, the parents are wronged because they’re normal in shape, or rather slim.
It’s a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say—not as I do.
【小題1】What is the “strange” point mentioned in the first sentence?

A．The good life is a greater risk than the bad life.
B．Starvation is taking more people’s lives in the world.
C．WHO report shows people’s unawareness of food safety.
D．Overweight issue remains unresolved despite WHO’s efforts.
【小題2】Why does the author think that people have no excuse for being overweight?
A．A lot of effective diet pills are available.
B．Body image has nothing to do with good food.
C．They have been made fully aware of its dangers.
D．There are too many overweight people in the world.
【小題3】The example of Finland is used to illustrate ______.
A．the cause of heart disease
B．the fashion of body shaping
C．the effectiveness of a campaign
D．the history of a body-conscious country
【小題4】Which would be the best title for the passage?
A．Actions or Excuses?B．Overweight or Underweight?
C．WHO in a DilemmaD．No Longer Dying of Hunger

When we think of green buildings, we tend to think of new ones-the kind of modern, solar-paneled masterpieces that make the covers of architecture magazines．But the US has more than 100 million existing homes, and it would be incredibly         to tear them all down and         them with greener versions．

An enormous amount of energy and resources went into the construction of those houses．And it would take an average of 65 years for the         carbon emissions (排放) from a(an) __     _ energy-efficient (節(jié)能) home to make up for the         lost by destroying an old one．

So in the broadest sense, the greenest home is the one that has already been built．But at the same time,          half of US carbon emissions come from heating, cooling and powering our          , offices and other buildings．"You can't deal with climate         without dealing with existing buildings," says Richard Moe, the president of the National Trust．

With some exceptions, the oldest homes tend to be the         energy-efficient．Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that         over time and let in more outside        .

      ,there are a vast number of relatively simple changes that can green older homes, from        ones like Lincoln's Cottage to your own postwar home．And efficiency upgrades (升級(jí)) can save more than just the earth; they can help         property owners from rising power        .

1.A． terrible  B．wasteful      C．wonderful   D．useful

2.A．put  B．build   C．replace        D．take

3.A．reduced  B．increased    C．used   D．destroyed

請(qǐng)認(rèn)真閱讀下面短文，并根據(jù)所讀內(nèi)容在文章后表格中的空格里填入最恰當(dāng)?shù)膯卧~。

注意：每空格1個(gè)單詞。

At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigour and resistance which, though not felt at first, will finally become so sudden and quick that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually die of old age, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favour of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer-- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and strong we are.

Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things 'wear out'. Most animals we commonly observe do in fact age as we do if given the chance to live long enough; and mechanical systems like a wound watch or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (whether the whole universe does so is a matter about which there may be disagreement or uncertainty at present). But these are not similar to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself, it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

 

The ____71____ of ageing

Infants and children under 12 are more easily ____72___ physically or emotionally.

At 12, we are ____73____ active and full of energy.

Later, we will ___74___ our energy or enthusiasm continuously.

Finally we can’t live any longer no matter how ___75___ we are cared for.

The characteristics of ageing

Not noticeable at first

Not avoidable in the end

Not the ____76___ speed for everyone

People’s misunderstanding of ageing

Just taking the ageing with time ____77___ for granted.

Simply thinking all living things or other systems also ___78___ the same way as we humans do.

Truth about ageing

We humans can ___79___ ourselves well enough to live a longer life, ___80___ the other living things or systems can’t.
