mention 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 greenhouse 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 is 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 are collecting. We need to face the wastefulness of our consumer culture, but we
have a mountain to climb.
B. Recycling too many wastes.
C. Making more products than necessary.
D. Having more material than is needed.
B. the increase of packaging recycling
C. the rapid growth of super markets
D. the fact of packaging overuse
B. means burning packaging for energy
C. is the solution to gas shortage
D. leads to a waste of land
B. Supermarkets care more about packaging.
C. It is improper to judge quality by packaging.
D. Other products are better packaged than food.
B. Needless material is mostly recycled.
C. People like collecting recyclable waste.
D. The author is proud of their consumer culture.

him shade; and they help to prevent from droughts and floods.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the
most important. In his eagerness to draw quick profit from the trees, he has cut them down in larg
e numbers, only to find that without them he lost the best friends he had.
Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which
to gain itself an empire. It gained the empire, but without its trees its soil became hard and poor. When the empire fell to pieces, the country found itself faced with floods and starvation.
Even when a government realizes the importance of a plentiful supply of trees, it is difficult for it to
persuade the villagers to see this. The villagers want wood to cook their food with; and they can earn
money by making charcoal or selling wood to the town man. They are usually too busy or too careless to
plant and look after new trees. So, unless the government has a good system of control or can educate
the people, the forests will slowly disappear.
This does not only mean that the villagers" sons and grandsons have fewer trees. The results are even
more serious: for where there are trees, their roots break the soil up-allowing the rain to sink in-and also
bind the soil, thus preventing its being washed away easily; but where there are no trees, the rain falls on
hard ground and flows away on the surface, causing floods and carrying away with it the rich top-soil, in
which crops grow so well. When all the top-soil is gone, nothing remains but worthless desert.
there"s the risk of dehydration (脱水).But athletes now know they can also get into trouble by drinking
too much. Too much water intake can lower levels of sodium (钠) in the blood .The death of a 28-year
-old woman following the Boston Marathon caught the attention of many runners and led to new research.
Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep
someone from not getting dehydrated by more than 2 percent of their body weight.
One technique for deciding how much water you need is to get the exact numbers. Runners have to
weight themselves before and after a run to determine how much water they"ve lost. If their weight drops
by more than 2 percent, they have not drunk enough water.
Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study
published last year tested 488 runners who completed the Boston Marathon and found 13 percent of
them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the
hands. They can"t get their rings off, and then they might feel sick. They may not remember where they
are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run.
Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the
new research has shown that the body is a remarkable machine that actually tells you via thirst when you
need water .
B. the long distance runners who need help
C. how to manage water intake during a marathon
D. a 28-year-old woman who died after a Boston Marathon
B. They can learn how much salt there is in the blood.
C. They can know the quantity of water they"ve lost during a run.
D. They can decide what kind of water they should take during a run.
B. Either too much or too little of water intake is harmful.
C. A rich meal is helpful to our performance in a run.
D. We should take enough salt during a run.
B. Too much water intake→blood salt levels ?→hyponatremia .
C. No water intake→blood sodium levels↑→hyponatremia .
D. No water intake →blood salt levels ?→hyponatrenmia .
they do not only look younger and slimmer, but feel better. Because of increased physical fitness, life
expectance in the nation has risen to seventy-three years, with fewer people suffering from heart disease,
the nation"s number one killer.
Jogging ( 慢跑 ), the easiest and cheapest way of improving the body, keeps over 30million people
of all ages on the run. For the price of a good pair of running shoes, anyone anywhere can join the race.
Dieting, too, has become a national pastime. Promoters of diets that eliminate eating one thing or another, such as fats or carbohydrates ( 碳水化合物 ), promise as much as 20- pound weight losses within two
weeks. Books describing such amazing diets always head up ( 居……之首 )the best-seller lists because people who are overweight want to lose weight quickly and easily.
Nevertheless, jogging and dieting, carried to extremes, can be harmful. Many confused joggers
overdo and finally suffer from ankle and foot damage. Dieting, fortunately, becomes only a temporary
means for shedding a few pounds while the body lose the balanced nutrition ( 营养 )it requires, so most
dieters cannot keep on diets. Above all, common sense should be the keystone for any dieting and
exercise plan.

Dad in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety
belt-a mistake 75% of the US population make every day. The big question is why.
There have been many myths about safety belts ever since heir first appearance in cars some forty
years ago. The following are three of the most common.
Myth Number One: It"s best to be "thrown clear" of a serious accident.
Truth: Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough
to give you a very bad landing. And chances are you"ll have traveled through a windshield (挡风玻璃)
or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in
cases where people are "thrown clear."
Myth Number Two: Safety belts "trap" people in cars that are burning or sinking in water.
Truth: Sorry again. but studies show that people knocked unconscious (昏迷) due to not wearing
safety belts have a greater chance of dying in these accidents People wearing safety belts are usually
protected to the point of having a clear head to free themselves from such dangerous situations, not to be
trapped in them.
Myth Number Three: Safety belts aren"t needed at speeds of less than 30 miles per hour.
Truth: when two cars traveling at 30 m/ph hit each other, an unbelted driver would meet the
windshield with a force equal to diving headfirst into the ground from a height of 10 meters.
B. He didn"t have his safety belt on.
C. He was running across the street.
D. He didn"t take his medicine on time.
B. hated to drive in the dark
C. wanted to take some exercise
D. didn"t want to be caught by the police
B. may be knocked down by other cars
C. may find it impossible to get away from the seat
D. may get caught in the car door
B. Never forget to wear the safety belt while driving.
C. Try your best to save yourself in a car accident.
D. Drive slowly while you"re not wearing a safety belt.
