runs out in the middle of a call?
If yes, then here comes some good news. Scientists are now perfecting a way to recharge (充电)
electrical equipment while on the move.
Researchers from the Netherlands, France and Portugal announced last week that they have developed
very thin solar panels (太阳能板) that can be put on clothes. They can also be added to furniture and
rooftops. They change light from the sun into electricity.
In about three years, you"ll be able to wear a jacket that will recharge your phone as you walk. For
camping fans, the development could lead to a tent which charges batteries all day so you can have light
or music at night.
The basic technology of wearable solar panels is the same as that used for conventional (传统的) solar
panels. Pairs of sheets of semi-conducting silicon (半导体硅) are linked together to form the panel.
But scientists made them much thinner by using different silicon. At one micro-metre, they are the
same thickness as photographic film.
"This technology will make it easier for people to use clean energy sources," said Gerrit Kroesen, a
physicist in the Netherlands who led the team of scientists.
But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an
efficiency of about 20 per cent, the new flexible (柔韧的) panels are only 7 per cent efficient. But the
scientists believe that this is worth accepting for a stronger and more useful panel.
But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket costs less than US$13.
It could charge a cellphone during a summer walk in the countryside. As long as you stay within range of
the transmitting masts (发射天线) that relay a call to the networks, phones will never again run out of power.
B. Going from one place to another.
C. Changing clothes before moving.
D. Changing the mobile phone battery.
B. A new kind of chargeable battery.
C. A new type of mobile phone.
D. A use of mobile phones.
B. Warmer clothes.
C. Furniture and rooftops.
D. Thin flexible solar panels.
B. Your mobile phone battery runs out in the middle of a call.
C. You wear a jacket that will recharge your phone.
D. You can change light from the sun into electricity.

environment, an official of the China Cuisine Association (中国烹饪协会) said.
Bian Jiang, its secretary general, recently called on restaurant owners to say no to one-off tableware
(餐具), especially wooden chopsticks. "The country produces and throws away over 45 billion pairs of
wooden chopsticks every year, at a cost to the environment of about 25 million tree." Bian said.
"That"s a heavy blow to the county"s shrinking forests," he said, "We should not turn a deaf ear to the
call for environmental protection. We should stop using disposable tableware from now on."
In order to discourage the use of wooden chopsticks and to protect wooden resources, the government
put a 5% tax on them in April.
The use of disposable chopsticks has been discussed for years. Their supporters say that both restaurant
owners and consumers prefer them, and that an industry has grown up around their production.

still. On the far side of the water is some farmland and further away, across the field, is an old church built
on a hill. It has just stopped raining. The brook (小溪) flowing into the lake is full and there is still some
half-melted (半融化的)snow from last winter on the ground.
The reason why the water is so clear, and everything is so quiet and still, is that most of the plant and
animal life in and around the lake is dead. There are no birds because all the fish and insects, which the
birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark (树皮), and
are sick and dying. Others were blown down by the high winds of last winter, A farmer is working in a field
planting something, but unless he plants a stronger kind of seed this year. the crop will be between 25 to 40
percent lower than a few years ago. The stones of the old church tower are turning to powder and unless
the tower is repaired soon, it will fall down.
All the death and destruction in this place is caused by the smoke coming out of factories and poisonous
gases from cars and trucks. And yet this silent lake is hundreds of kilometers away from the nearest factory
and highway.
B. Summer
C. Autumn
D. Winter
B. the area is polluted
C. the lake is quiet
D. they have all been killed
B. few plants can grow because of the pollution
C. the water in the lake can"t be used to irrigate the field

(一次性的) toothbrushes, toothpaste, shampoo and slippers.
Many guests like the idea because they don"t have to bring their own. But, if you travel to Beijing,
remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests
with these disposables. They want to ask people to use less disposable things. Many disposable things are
made of plastic, not easy to rot away. People throw them away after using them only once. It is a waste of
natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as
400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away
about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between
100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring
your own things and use them again and again.
At home and school, you can also do something to make our world a better place. Try to use daily
necessities (日用品) once more. Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it
out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen,
use your own bowl and chopsticks instead of disposable ones.

When you haven"t got it, you think about it all the time. Our biggest enemies are not terrible diseases. We
are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too
much, drink too much and smoke too much. And though our reason tells us we should control ourselves,
we find it difficult. The fact is that most human beings need stimulation.(刺激) Who doesn"t enjoy a drink
after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee.
The danger is when these innocent pleasures run our lives and so destroy our health. When you find
yourself eating between meals or eating too much rich food, when you can only keep yourself going by
taking frequent drinks or by smoking one cigarette after another, then it"s time to stop and think what you
might be doing to yourself. The funny thing is that when we don"t control ourselves, simple pleasures are
no longer simple pleasures.
All right, I know what you"re thinking. You"re probably saying: "It"s all very well for him to talk, but I
can"t help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many
pressures that I can"t manage without them." But I"m saying you can help yourself. Not only that you must
help yourself. Because if you don"t help yourself, no one else can. So be your own best friend.
B. work
C. friendship
D. good health
B. pleasures after a busy day
C. the danger of too much drinking, smoking and eating
D. the difficulty of controlling ourselves
B. I must ask someone for help
C. I can"t control myself
D. Do help me, please
B. Have a cigarette with a cup of coffee.
C. Eat as much rich food as you can.
D. Be your own best friend and control yourself
of chocolate you know that these are things you can eat. You can also use other senses when you choose
your food. You may like it because it smells good or because it tastes good. You may dislike some types of
food because they do not look, smell or taste very nice. Different animals use different senses to find and
choose their food. A few animals depend on only one of their senses, while most animals use more than one
sense.
Although there are many different types of food, some animals spend their lives eating only one type. The
giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food
even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though
there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮
食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will
be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In
countries such as France and Britain, people eat foods with too much sugar. This makes them overweight,
which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad
for the health. Choosing the right food, therefore, has become an area of study in modern life.
B. are not satisfied with their food
C. choose food in similar ways
D. eat entirely different food
B. the food color changes
C. they move to different places
D. they are attracted by different smells
B. French and British food is good
C. some people have few choices of food
D. some people care little about healthy diet
