When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them.
However,when the Lascaux cave complex was discovered in 1940,the world was amazed.
Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.
Early artists drawing these animals accomplished a monumental and difficult task. They did not limit themselves to the easity accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex.
Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes,which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside.
Although they are not out in the open air, where natural light would have destroyed them long ago,many of the images have deteriorated and are barely recognizable. To prevent further damage,the site was closed to tourists in 1963,23 years after it was discovered.

A few minutes ago, walking back from lunch, I started to cross the street when I heard the sound of a coin dropping. It wasn't much but, as I turned, my eyes caught the heads of several other people turning too. A woman had dropped what appeared to be a dime.
The tinkling sound of a coin dropping on pavement is an attention-getter. It can be nothing more than a penny.Whatever the coin is, no one ignores the sound of it.It got me thinking about sounds again.
We are besieged(包围) by so many sounds that attract the most attention. People in New York City seldom turn to look when a fire engine, a police car or an ambulance comes screaming along the street.
When I'm in New York, I'm a New Yorker. I don't turn either. Like the natives.
At home in my little town in Connecticut, it's different. The distant wail of a police car, an emergency vehicle or a fire siren brings me to my feet if I'm seated and brings me to the window if I'm in bed.
It's the quietest sounds that have most effect on us, not the loudest. In the middle of the night, I can hear a dripping tap a hundred yards away through three closed doors.I've been hearing little creaking noises and sounds which my imagination turns into footsteps in the middle of the night for twenty-five years in our house. How come I never hear those sounds in the daytime?
The sound of a coin dropping makes people________.
A.think of money
B.look at each other
C.pay attention to it
D.stop crossing the street

People in New York________.
A.don't care about emergencies
B.are used to alarm
C.are attracted by sounds
D.don't hear loud noises

C.He thinks taps should be turned off.
D.He believes it's rather quiet at night.
43、

Twelve years ago, oceanographer Captain Charles Moore was skippering his yacht the Alguita in the North Pacific. He sailed into a mass of floating plastic rubbish which took him and his crew a week to cross. This floating rubbish dump is now called the Great Pacific Garbage Patch and doubles the size of the USA.
The United Nations says there are now 18,000 pieces of plastic in every square kilometre of sea everywhere in the world. A walk along any beach will give you some idea of the seriousness of plastic pollution.
The trouble is, when we throw out plastic with the trash, the plastic doesn't go away. Plastic does not biodegrade. It photo degrades into smaller and smaller particles which then enter the food chain.
Plastics contain cancer-causing chemicals along the food chain in increasing concentrations and end up in our fish and chips, along with hormone disruptors. Scientists try to tell us that we are killing ourselves as well as other animals. At least 200 species are, as I speak, being killed by plastic.
Whales, dolphins, turtles and albatross confuse floating plastic, especially shopping bags and six pack rings, with jellyfish.
Some countries have rebelled and banned plastic bags. And the first was brave Bangladesh. Then China took the same decision. Botswana, Canada, Israel, Kenya, Rwanda, Singapore and South Africa have also banned plastic bags. Notice how many of the world's richest countries are not on this list. It's an absolute disgrace.
Think globally, act locally. A small Australian town is now one step ahead of the rest of the world. The inhabitants of Bundanoon in New South Wales have banned plastic bottles from the town.
We need to follow their example and eliminate plastic from our lives, take care of the earth and vote for people we think will do the same.
The writer says that we can get an idea of how much plastic rubbish there is in the oceans by________.
A.looking at the sea
B.travelling across the USA
C.sailing across the Pacific
D.taking a walk along any beach
45、
The reader learns that toxic chemicals get into our food________.
A.when plastic becomes small enough to enter our food chain
B.because other animals are being killed by plastic
C.because plastic does not biodegrade
D.from plastic bags from supermarkets
