阅读理解     There was one thought that air pollution affected only the area immediately around large cities with
factories and heavy automobile traffic. At present, we realize that although these are the areas with the
worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud
of air pollution has covered the east of the United States and brought health warnings in rural areas away
from any major concentration (集中)of manufacturing and automobile traffic. In fact, the very climate of
the entire earth may be infected by air pollution.
     Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from
the burning of coal and oil is creating a "greenhouse effect" - raising the world"s average temperature. If
this view is correct and the world"s temperature is raised only a few degrees, much of the polar ice will
melt and cities such as Newk York, Boston, Miami, and Newk^ Orleans will be in water.
     Another view, less widely held, is that increasing particular matter in the atmosphere is preventing
sunlight and lowering the earth"s temperature - a result that would be equally disastrous. A drop of just
a few degrees could create something close to a new ice age, and would make agriculture
difficult or impossible in many of our top farming areas. Today we do not know for sure that either of
these conditions will happen though one recent government reports that the greenhouse effect is very
possible. Perhaps, if we are lucky enough, the two tendencies will offset(抵消)each other and the world"s
temperature will stay about the same as it is now. Driven by economic profits, people don"t think about
the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price
the human beings have to pay for their development. But is it really worth?2. As pointed out at the beginning of the passage, people used to think that air pollution ________.A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaged effect on health
D. existed only in urban and industrial areas3. As to the greenhouse effect, the author ________.A. shares the same view with the scientists
B. is uncertain of its happening
C. rejects it as being ungrounded
D. thinks it will destroy the world soon4. It can be concluded from the last paragraph that ________.A. lowering the world"s temperature only a few degrees would lead major farming areas to disaster
B. raising the world"s temperature only a few degrees would not do much harm to life on earth
C. almost no temperature variations have occurred over the past decade
D. the world"s temperature will remain constant in the years to come5. This passage is mainly about ________.A. the greenhouse effect
B. the burning of coal and oil
C. the potential effect of air pollution
D. the likelihood of a newk ice age

     Many solutions we seek with regard to achieving sustainability(可持续性) are within our reach.
That"s the lesson our school"s Environment Club has learned over the past two years. We"ve reduced
the amount of our waste at our school by 25 per cent.    1     We have the evidence we need to
suggest we are making a difference. If you are interested in leading your school on a similar journey
of change, here are some tips.
      2
   Examine the garbage can to find out how much of your school"s garbage could be picked out from
the waste stream and be reused. We found that more than 80 percent of our waste could have been
reused, recycled or composted(制成堆肥).
    Prepare dustbins there.
      3   You will find you can cover the cost of the purchase of the dustbins within a few months simply
by selling the bottles and other items you collect.
    Compost the waste.
    Start a composting system in your school. You may reduce your waste by as much as 50 percent.
Be sure to talk with your teachers and your cafeteria staff to get them onside.
    Share your success.
   Let your community know what you"ve accomplished.    4 Ask your teachers if you can talk to
their classes, let your parent group know what you"re doing, and present a report to the president of
your school.
      5
    Whether you spend a few moments in a quiet place or the whole day walking along a beautiful beach,
time outdoors will remind you why the work you do for the environment is so worthwhile.
A. Dig in.
B. Reward yourself.
C. Do outdoor activities.
D. They"ll feel proud of you.
E. We need to go further, and we will.

阅读理解     Wherever life takes you after A-level results day, it"s likely to bring increased independence. That
means it"s time to take care of yourself.
     Students, take note. When you arrive at university, make sure you register with a doctor near your
term-time address. If there is a university doctor at your institution, they will be your best choice. If not,
ask student services for a recommendation. Once registered, do everything you can to make sure you
never have to pay them a visit. Don"t take unnecessary health risks.
     Cook meat thoroughly. Throw food away if it"s out of date. Clean up after yourself. Food poisoning
can be harmful, but it"s easy to avoid if you pay due care and attention.
     University often brings a certain lifestyle, and while that"s usually a whole lot of fun, it can quickly tip
into a whole lot of sorrow. Know your limits when it comes to alcohol. Habitual drinking can be
dangerous, and while every student will have nights of excess, these should be the exception, not the
norm. Look out for your friends, too. If you"re worried about alcohol or substance abuse, visit
alcoholics-anonymous.org.uk <http://alcoholics-anonymous.org.uk> or ukna.org http://ukna.org
for free and confidential support.
     Anyone living with teenagers and young adults, especially in environments such as halls of residence,
must accept that germs (细菌) will be shared. Bugs and colds will spread like wildfire. Living
communally brings certain health risks, and meningitis is probably the most serious of these. Symptoms
include a rash, stiff neck and an aversion to bright lights. It"s rare, but seek immediate medical attention
if you"re concerned (meningitis.org <http://meningitis.org>).
     Gappers, meanwhile, may need to consider specific health risks. If you"re planning a trip abroad,
especially in rural areas of poor countries, make sure you get the necessary vaccinations (预防注射) in
good time before you leave.
     Research these at www.netdoctor.co.uk <http://www.netdoctor.co.uk>. You should be able to get everything you need from your doctor, although you may have to give them notice and you may have to pay, even on the NHS (英国国家医疗服务体系). If you also need to take medication while you"re away, such as anti-malarials, do it faithfully.
      On a general note, whoever you are, wherever you are and whatever you do with your time, never walk alone at night, especially in quiet and badly lit areas. Always carry your phone. Never get in an unlicensed cab. Be careful who you trust. Respect your new independence, and keep yourself safe.1.

     We produce 500 billion of plastic bags in a year world-wide and they are thrown
away polluting oceans, killing wild-life and getting dumped in landfills where they take
up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a
solution.
    The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate
Institute, has discovered a-way to make plastic bags degrade(降解)in as few as 3months,
a finding that won him first prize at the Canada-Wide Science Fair, a $10,000 prize, a
$20,000 scholarship, and a chance to revolutionize a major environmental issue.
    Burd"s strategy was simple: Since plastic does eventually degrade, it must be eaten by
microorganisms(微生物). If those microorganisms could be identified, we could put them
to work eating the plastic much faster than under normal conditions.
    With this goal in mind, he ground plastic bags into a powder and concocted(调制)a
solution of household chemicals, yeast(酵母)and tap water to encourage microbes growth.
Then he added the plastic powder and let the microbes work their magic for 3 months. Finally,
he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead
bacteria as a control. Sure enough, the plastic exposed(暴露)to the live bacteria was 17%
lighter than the control after six weeks.
    The inputs are cheap: maintaining the required temperature takes little energy because microbes
produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
    "Almost every week I have to do chores and when I open the closet door, I have piles of plastic
bags falling on top of me. One day, I got tired of it and I wanted to know what other people are
doing with these plastic bags. The answer: not much. So I decided to do something myself." said
Daniel Burd.

1．Daniel Burd won first prize at the Canada-Wide Science Fair because ____.   A．he found a new kind of microorganism
B．he contributed much to environmental protection
C．he found a way to degrade plastics in shorter time
D．he could encourage microbes growth in an easier way2．Daniel Burd exposed one plastic sample to dead bacteria to       A．make the live bacteria work better
B．test how effective his method was
C．know which bacteria worked faster
D．control the temperature in the process3．Maintaining the required temperature takes little energy because ____.  A．plastics can get hot easily
B．microbes can produce heat themselves
C．much carbon dioxide is produced
D．the temperature can be controlled4．Daniel Burd got his idea from ____.   A．his school textbook

阅读理解。     Secondhand smoke isn"t just a health threat to people. It can also hurt dogs and cats,veterinarians
say.
     According to the Centers for Disease Control and Prevention,more than 126 million Americans
who don"t smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public
places. This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers
every year,according to the California Environmental Protection Agency.
     "Making the leap from the effects of secondhand smoke on humans to their effects on pets isn"t a
big one," says veterinarian (兽医专家) Carolynn MacAllister of Oklahoma State University.
     "There have been a number of scientific papers recently that have reported the significant health
threat secondhand smoke poses to pets," MacAllister said. "Secondhand smoke has been associated
with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds."
     Studies have also shown that dogs living in a smoking household are susceptible to cancers of the
nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater
surface area that is exposed to carcinogens and a greater area for them to accumulate. Dogs affected
with nasal cancer normally don"t survive for more than one year.
     "Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal
passage aren"t as effective at accumulating the inhaled secondhand smoke carcinogens," MacAllister
said. "This results in more carcinogens (致癌物质) reaching the lungs."
     Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are
hypersensitive to any type of air pollutant.
     To help prevent animals from being adversely affected by smoking,pet owners who smoke should
have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister
said.          1. From the passage,we can see secondhand smoke maybe not harmful to _______. A. smokers
B. non-smokers
C. pets
D. trees2. What can be suggested according to the passage?A. Smokers can smoke anywhere.
B. Smokers can smoke at any time.
C. Smokers should smoke in the designated place.
D. Smokers must give up smoking at once.3. What kind of dogs are likely to suffer from nasal cancer?A. Long-nosed dogs
B. Short-nosed dogs
C. Medium-nosed dogs
D. Dogs without noses4. The best title of the passage is __________.A. Secondhand Smoke Causes Cancer in People
B. Secondhand Smoke Causes Cancer in Birds
C. Secondhand Smoke Causes Cancer in Pets
D. Secondhand Smoke Causes Cancer in Cats5. What is the meaning of the underlined phrase "are susceptible to"?A. are likely to be harmed by
B. are hard to be influenced by
C. are less to be effected by
D. are lucky to be caught by

阅读理解     Living in a green area can make you live longer, according to the research published today. The
research also shows that the difference in life expectancy (平均寿命) between rich and poor becomes
smaller among those who live in an environment with parks and trees.
     Richard Mitchell, from Glasgow University, and his colleagues, found that the gap between the
number of deaths of people on high incomes and the number of deaths of those on low incomes in
green areas was half that compared with figures relating to builtup areas.
     Green spaces, classified by the researchers as "open, undeveloped land with natural vegetation",
encouraged people to walk and be more active. Exercise in these settings could have greater benefits
than exercise elsewhere, the researchers said.
     The benefits potentially go beyond exercise. Studies have shown that being around green spaces
can reduce blood pressure and stress levels, and possibly help patients recover faster.
     A number of researchers have looked at the effects of greenery on our wellbeing. But few studies
had looked at whether living in green areas reduced health inequalities, the Glasgow team said.
     Using information from a landuse database of 2001, the researchers divided the preretirement
population of England into four groups according to income level, and five groups according to access
to green space. They then looked at death rate for 2001-2005.
     They found that the inequality in death rate from all causes relating to lack of money was less in
those populations in the greenest areas compared with the figures for people living in more builtup
places. They found an even stronger relationship when it came to deaths from certain diseases such
as heart conditions and stroke (中风). There was no difference, however, in deaths from lung cancer.
     The researchers said that changing the physical environment was an easier way to fight against poor
health than using media campaigns or giving out information on health. "The result of the study is clear,
environments that promote good health might be very important in the fight to reduce health inequalities."1. The underlined word "that" in Paragraph 2 refers to ________.A. the gap
B. the number of deaths
C. the income
D. the living area2. What was the special point of the Glasgow team"s research? A. They offered a scientific definition of "green spaces".
B. They encouraged people to exercise in green areas.
C. They studied the effects of greenery on people"s diseases.
D. They focused on the influence of greenery on health inequalities.3. What advice would the researchers probably give according to the last paragraph? A. More health information should be given to the public.
B. People should take more exercise every day.
C. More trees and grasses should be planted in cities.
D. People should fight against health inequality.4. What is the main idea of the passage?   A. People should live in green areas.
B. Green spaces promote good health.
C. Income influences health less than environment.
D. Exercise in green areas benefits people a lot.
