recycling. Recycling in the home is very important of course. However, being forced to recycle often means
we already have more material than we need. We are dealing with the results of that over-consumption in the
greenest way possible, but it would be far better if we did not need to bring so much material home in the first
place.
The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a
typical household"s waste in the UK. In many supermarkets nowadays food items are packaged twice with
plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of
it for carrying this unnecessary waste. If such packaging is burnt, it gives off green-house gases which go on
to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to
produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage
customers to buy more than they need. However, a few of them are coming round to the idea that this cannot
continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with
quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food.
But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary
material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain
to climb.

years. Liu, 15, is a Junior 2 student at Chicheng No. 2 Middle School. He began smoking four years ago.
"Smoking is part of my life," Liu said. Qiao and Liu are not those boys" real names. But their problem, smoking,
is a very real problem. In many countries, smoking is becoming a bigger problem for young people. Most
smokers start in their teens (years of a person"s age from 13 to 19) or earlier.
A study of 8,000 Beijing students last May told us that smoking is a problem for many Chinese kids.
More than 21% of middle school students and 6% of primary school pupils said they smoked.
"If young people start smoking early, they will probably get addicted to nicotine. And it will be very hard
to give up later on," said a professor.
Every year, about four million people die because of smoking. And if people keep smoking, that number
will go up to about 10 million a year by 2030, the World Health Organization (WHO) says. So we have to
learn and tell others about the dangers of smoking.

Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about
attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical
opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger
was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So
did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt
in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a
bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor
ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply
and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have
moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter
than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children
off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an
American immunologist (免疫学家), encourages children to play in the dirt to build up a strong immune
system. And the latter position is gaining some ground.
B. they thought bath houses were to dirty to stay in
C. they believed disease could be spread in public baths
D. they considered bathing as the cause of skin disease
B. Curious
C. Approving
D. Uninterested
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance.
B. To introduce the history of dirt.
C. To call attention to the danger of dirt.
D. To present the change of views on dirt.
the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs
while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite
exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to
finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is of my face. It"s
a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through
each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just
one bite of their grandmother"s chocolate cake. They raise their eyebrows, surprised by my "no thank you," or
by my choice to have a salad. Over the years, I have learned it"s okay to just say "no." I shouldn"t feel sorry for
refusing food that I don"t want to eat.
So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say to ice cream?
Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self-confidence
and energy, extends life and above all improves my body shape. This is the point where a smile appears on my
face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It"s through
commitment and sweat that I can make a difference within myself inside and out.

environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing
but bad news about the environment. The "eco-guilt" brought on by the discouraging about our planet gives
rise to the popularity of skeptics as people search for more comforting worldviews.
Perhaps that explains why a new book by Bjorn Lomborg received so much publicity. That book, The
Skeptical Environmentalist, declares that it measures the "real state of the world" as fine. Of course, another
explanation is the deep pockets of some big businesses with special interests. Indeed, Mr. Lomborg"s views
are similar to those of some Industry-funded organizations, which start huge activities though the media to
confuse the public about issues like global warming.
So it was strange to see Mr. Lomborg"s book go largely unchallenged in the media though his beliefs were
contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews
full of words of praise, even with the conclusion that "After Lomborg, the environmental movement will begin
to die down."
Such one-sided views should have immediately been challenged. But only a different review appeared in
Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg"s
"preference for unexamined materials is incredible (不可信的)".
A critical (批判的) eye is valuable, and the media should present information in such a way that could
allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire
to be shocking or to defend some special interest. People might become half-blind before a world partially
exhibited by the media. That"s a shame, because matters concerning the health of the planet are far too
important to be treated lightly.
B. People who disbelieve the serious situation of our planet.
C. People who dislike the harmful effect of human activities.
D. People who spread comforting news to protect our environment.
B. The book challenges views about the fine state of the world.
C. The author convinces people to speak comforting worldviews.
D. Industry-funded media present confusing information.
B. find fault with Lomborg"s book
C. challenge the authority of the media
D. point out the value of scientific views.
B. To warn the public of the danger of half-blindness with reviews.
C. To blame the media"s lack of responsibility in information.
D. To show the importance of presenting overall information by the media.
so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be
that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead
students aren"t used to the early hour.
"Maybe these kids me being asked to rise at the wrong time for their bodies," says Mary Carskadon, a
professor looking at problem of adolescent (青春期的) sleep at Brown"s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more
basic level. She and her team are trying to learn more about how the biological changes of adolescence affect
sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less,
as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer
to stay up later at nigh and sleep later in the morning. But it"s not just a matter of choice-their bodies are going
through a change of sleep patters.
All of this makes the transfer from middle school to high school-which may start one hour earlier in the
morning-all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks
set on the "sleep late, rise late" pattern, adolescent are up against difficulties when it conics to trying to be up
by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body"s way of saying. "I need
a timeout."
B. it is biologically difficult for students to rise early
C. students work so late at night that they can"t get up early
D. students are so lazy that they don"t like to go to school early
B. agree with others
C. full asleep
D. refuse to work
B. Adolescents have to choose their sleep patterns.
C. Adolescents sleep better than they did at childhood.
D. Adolescents need more sleep than they used to.
B. Problems in adolescent learning.
C. Adolescent sleep difficulties.
D. Changes in adolescent sleep needs and patterns.
