Think about what you like to wear on the weekend.There's a good chance that you like to put on a pair of blue jeans.At any moment,about half of the world's population is wearing jeans.But according to a new study,our love for jeans may be bad for Earth.Denim (牛仔布)might be putting some sea animals in danger.

Every time we wash our jeans,tiny bits of denim will flow out of our washing machines,down into the world's rivers,lakes and oceans.

You might wonder:Isn't denim made of cotton,a natural material?How can it become a danger to nature?Well,in the process of making jeans,denim is treated with many types of man﹣made chemicals.Some improve its durability (耐用性)and feel;others give jeans their blue color.

Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada.They found denim waste in all of the samples (样本)they had collected.It is feared that the harmful chemicals in denim have spread far and wide.Scientists aren't yet sure how these chemicals might harm animals.

In the study,the scientists also washed jeans to see how many bits of denim each pair would drop per wash.The answer was frightening:About 50,000.Not all of them make their way into the environment.Wastewater treatment plants hold back 83 to 99 percent of them.This may sound pretty good.However,one percent of 50,000 bits are still 500 per wash.Now think about the number of jeans around the world and the times each of them gets washed.As a result,a large amount of denim waste still gets into the environment.

Does this mean we shouldn't wear jeans?Probably not" We need to buy fewer jeans and only wash them when we truly need to do it," says Sam Athey,one of the scientists. " You don't need to wash your jeans after having worn them only a couple of times. "

①To save the materials and make more money.

A.

①②

B.

C.

②③

(3)How many bits of denim might get into the environment every year?    

A.

Five hundred.

B.

Fifty thousand.

C.

Too many to count.

(4)What should we do according to Sam Athey's words?

When you are about to do something brave, a cheerful wish of “Good luck!” from a friend can be helpful. But if you think you need lots of luck, what else might you do?
In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer.
Have you heard the saying “When you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn’t happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true.
Maybe you have heard of the lucky rabbit’s foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit’s feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, “Depend on the rabbit’s foot if you will, but remember it didn’t work for the rabbit!”
People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole of good luck!
