You may know that more people drink coffee than tea around the world.And that, after oil, it is the second biggest traded commodity (商品).You may also know that the drink comes from beans which are first roasted and then ground (研磨).But what else do you know about this popular drink?

It is said that the story of coffee started with an Ethiopian goatherd (牧羊人) named Kaldi.One day Kaldi was surprised to see that his goats were behaving very strangely.Instead of grazing (吃草) quietly, they were jumping around, almost dancing.He also noticed some red "cherries" from a plant that the goats were eating.He tried some himself and was surprised by the feeling of extreme happiness and excitement.He felt like dancing too !

But it wasn't used as a drink at first.It was used as food.The coffee berries, mixed with animal fat, were used by monks to stay awake during long hours of prayer.From Ethiopia, coffee was later cultivated (培育) in Yemen and the first hot drink was developed there around AD 1000.Three centuries later Muslims were keen coffee drinkers and as Islam spread, so did coffee.Coffee houses appeared in Cairo and Mecca.

For hundreds of years the plants were protected safely.But some beans were smuggled (偷运) out of Arabia and taken to India.In the 17th century, coffee was soon grown in a new continent.From India to Indonesia, a century later the beans were once again smuggled to Brazil.Brazil is now the largest coffee producer in the world.

It was the caffeine that made the goats dance and kept the monks awake.Although it is found in other soft drinks and tea, coffee has the most caffeine.In the short term.a couple of cups of coffee can prevent fatigue and delay sleep.But several cups a day, every day, can cause anxiety and restlessness.

Elephants losing tusks

People killing elephants for their tusks has long been a problem worldwide. Although laws have been introduced to ban the selling of tusks, they have not been enough to save the elephants.

But the giant animals have now “developed” their own solution to stay safe from hunters----by not growing tusks at all.

Scientists found that among female African elephants, as many as 98 percent of them now have no tusks, reported The Independent newspaper. The number was 15 percent in 1998 and only 1 percent in 1930, according to the BBC.

But this solution has less been developed by elephants themselves, and more by evolution.

Evolution is all about natural selection(选择). When an environment changes, for example, animals and plants that can deal with the change will stay alive while others won’t. And for elephants, the change came when hunters started killing them for their tusks. As a result, elephants with big tusks couldn’t stay alive because hunters wanted to shoot them. Those born with tusks managed to stay alive and give their “tuskless” genes(基因)to their babies. As a result, more and more elephants are now being born without tusks.

But this solution, as effective(有效地)as it might be, is a high price to pay for elephants. Tusks are important and play a number of roles, especially for male elephants, including fighting with other males, lifting and digging things up.

This is why scientists hope there can be other ways to protect elephants against hunters. They believe that when they are less likely to be killed , elephants will be able to grow tusks again.

To David Cowdrey, head of Policy and Campaigns at the International Found for Animal Welfare UK, however, this is not very likely to happen in the near future.

“Unfortunately, it comes down to the markets,” he told The Guardian. “As long as people will pay high prices for products that come from endangered animal and plants, they’re going to have price on them and that causes the hunting.”

1.Which of the following is TRUE according to the passage?

A. Elephants learned to lift and dig things up without tusks.

B. Elephants chose not to grow tusks because of their dangerous environment.

C. Elephants with no tusks had a greater chance of passing down their genes.

D. A tuskless elephant gives birth to more baby elephants than an elephant with big tusks.

2.The underlined word “evolution” in paragraph 4 means “_________” ?

A. gradual change B. sudden development C. complete loss D. rapid growth

3.What can you learn from the last two paragraphs?

A. We should work out a better solution to protect elephants.

B. People should pay lower prices for products made with elephant tusks.

C. Elephants’ living environments will soon be improved.

D. The key to elephant protection is stopping the trade in tusk products.
