When we think of animals and plants, we have a pretty good way of dividing them into two distinct groups:one converts sunlight into energy and the other has to cat food to make its energy. Well,those dividing lines come crashing down with the discovery of a sea slug(海蛞蝓)that's truly half animal and half plant.It's pretty incredible how it has managed to hijack the genes of the algae(藻类)on which it feeds. The slugs can manufacture chlorophyll, the green pig ment (色素)in plants that captures energy from sunlight,and hold these genes within their body. The term kleptoplasty is used to describe the practice of using hijacked genes to create nutrients from sunlight. And so far,this green sea slug is the only known animal that can be truly considered solar-powered, although some animals do exhibit some plant-like behaviors. Many scientists have studied the green sea slugs to confirm that they are actually able to create cnergy from sunlight. In fact, the slugsuse the genetic material so well that they pass it on to their future generations. Their babies retain the ability to produce their own chlorophyll, though they can't generate energy from sunlight until they've caten enough algae to steal the necessary genes, which they can't yet produce on their own. "There's no way on earth that genes from an alga should work inside an animal cell,"says Sidney Pierce from the University of South Florida."And yet here,they do. They allow the animal to rely on sunshine for its nutrition. So if something happens to their food source,they have a way of not starving to death until they find more algae to cat." The sea slugs arc so good at gathering energy from the sun that they can live up to nine months without having to eat any food. They get all their nutritional needs met by the genes that they've hijacked from the algae. 51.What is the distinctive feature of a sea slug? A) It looks like both a plant and an animal. B) It converts some sea animals into plants. C) It lives half on animals and half on plants. D)It gets energy from both food and sunlight. 52.What enables the sea slug to live like a plant? A) The genes it captures from the sea plant algae. B)The mechanism by which it conserves energy. c) The nutricnts it hijacks from other specics. D)The green pig ment it in herits from its ancestors. 53.What does the author say about baby sea slugs? A) They can live without sunlight for a long time. B)They can absorb sunlight right after their birth. C) They can survive without algae for quite some time. D)They can produce chlorophyll on their own. 54.What docs Sidney Pierce say about genes from an alga? A) They are stolen from animals like the sea slug. B) They can't function unless exposed to sunlight. C) They don't usually function inside animal cells. D)They can readily be converted to seaslug genes. 55.What do we learn about sea slugs from the passage? A)They behave the way most plant species do. B)They can survive for months without cating. C) They will turn into plants when they mature. D)They will starve to death without sunlight.

Diets have changed in China — and so too has its top crop. Since 2011, the country 1 (grow) more corn than rice. Corn production has jumped nearly 125 percent over 2 past 25 years, while rice has increased only 7 percent. A taste for meat is 3 (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice 4 (improve) water quality. Corn uses less water 5 rice and creates less fertilizer (化肥) runoff. This switch has decreased 6 (pollute) in the country's major lakes and reservoirs and made drinking water safer for people. According to the World Bank, China accounts for about 30 percent of total 7 (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005 — when the government 8 (start) a soil-testing program 9 gives specific fertilizer recommendations to farmers — and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission (排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while 10 (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide."says the bank's Juergen Voegele.
