Health experts are calling for action to expand cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But

now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the interna?tional community to fight cancer aggressively, saying it should be fought in the way HIV/AIDS has been fought in Africa.

Cancer kills more than 7. 5 million people a year worldwide. Almost two thirds are in low-income and middle-income countries. They discover cancer kills more people in developing countries than AIDS, tuberculosis(月巿结核)and malaria (疰疾)combined. But the world spends only 5 % of its cancer resources in those coun?tries.

Felicia Knaul from Harvard Medical School was one of the authors of the pa?per. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.

Felicia Knaul says, "And we are seeing how this is attacking young women. It's the number two cause of death in Mexico for women from thirty to fifty-four. All over the developing world, it's the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.,,

Professor Knaul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.

If you travel to a new exhibit at the San Francisco Conservatory of Flowers* you will have chances to see some meat-eating plants. Take bladderworts (狸藻类植物),a kind of such plants, for exam?ple. They appear so small and grow in a quiet pond. But they are the fastest known killers of the plant kingdom, and able to capture a small insect in 1/50 of a second using a trap door !

Once the trap door closes on the victim,the enzymes(酉每)similar to those in the human stomach slowly digest the insect. When dinner is over,the plant opens the trap door and is ready to trap again.

Meat-eating plants grow mostly in wet areas with soil that doesn't offer much food value. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents.

Generally speaking,the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers (罐)full of nectar(花蜜).

The Asian pitcher plant, for example,has bright colours and an attractive half-closed lid. Curious insects are tempted to come close and take a sip, and then slide down the slippery(光滑的)slope to their deaths.

Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days.

Some of these pitchers are large enough to hold two gallons. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or small animals will discover that a pitcher plant isn't a good place to get a drink.

1.     If the trap door of a meat-eating plant is closed,the plant is .

  A.  fooling insects into taking a sip

B.  producing nectar

C.  tempting insects to come close

D.  enjoying a dinner

2.     Meat-eating plants can grow in wet and poor soil because they ,

  A.  can get nutrition from insects

B.  don't need much food

C.  can make the most of such conditions

D.  have developed digestive enzymes

3.     What can be captured by meat-eating plants for food?

  A.  A child.

B.  A dog.

C.  A little bird.

D.  A little fish.
