Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food.
In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus (病毒) kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops.
Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri.
The lab mainly works on genes (基因), the chemical “computer programs” found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering.
Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes.
That’s just the beginning, Wambugu believes. Genetically modified (转基因的) foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.
【小题1】The text is written mainly to _______.
A.tell us sweet potatoes are in danger of being attacked by a virus |
B.introduce Wambugu’s contribution to genetic engineering |
C.introduce a new way of killing plant viruses |
D.tell how hard Wambugu worked in her lab for three years |
A.Her wish to save sweet potatoes in Kenya. |
B.Her great interest in genetic engineering. |
C.Her love for sweet potatoes. |
D.Her interest in plant life. |
A.a crop virus | B.chemical technology |
C.a computer program | D.genetic engineering |
A.It will help more hungry people. |
B.It should be carefully used. |

Koalas are pictured everywhere in Australia-on cleaning products, on “boxes of chocolate, on sports team shirts. Yet the animals live only in pockets along the east coast.
They once inhabited the entire coastline. The koala population dropped after farmers cut down many of the forests where koalas lived, and hunters killed the animals for their fur.
By the early 1900s, “koalas were basically shot out of south Australia,” says ecologist Bill Ellis, who studies the relationships among living things and their environments.
I recently joined Ellis and his team in a forest on St Bees Is land, 19 miles off the northeastern coast of Australia, with eight other volunteers. The island is a natural laboratory, yielding findings that may help protect koalas elsewhere on the continent.
The volunteers searched the island for koalas in the blue gum trees. When we found a koala, we gathered information about the trees in the area.
Blue gum is a species of the eucalyptus tree in which the funny leaf eaters spend most of their time. Eucalyptus trees are native to Australia, and their leaves are the main food source for koalas. Although koalas can walk on the ground, they are better suited for life in the canopy, the high cover of branches and leaves in a forest.
What has Ellis’s research told him so far? The population of St Bees seems to be healthy. Yet Ellis wonders whether the koalas might be heading for hard times. The island is overrun with wild goats, and Ellis thinks the goats are eating the small blue gum trees.
Without those trees, the koalas will run out of food in the future. Ellis hopes more research will help him understand how to protect the blue gum trees-and the koalas that depend on them. “I think that’s what everyone is trying to do-to make a difference.” Ellis says.
59. It can be inferred from the first paragraph that .
A. koalas’ pictures can be found everywhere in the world
B. koalas in Australia like to eat chocolate
C. only in the east coast of Australia can you find koalas
D. you can buy the pictures of koalas only in the east coast of Australia
60. Which of the following is TRUE about koalas?
A. They usually hide in a cave. B. They feed on the leaves of blue gum trees.
C. They prefer to walk on the ground. D. They don’t adapt to the high cover of branches.
61. What will Ellis most probably start to do next?
A. To keep the population of St Bees healthy.
B. To kill all the goats on the island.
C. To find some new foods for goats.
D. To protect blue gum trees for koalas.
62. The purpose of writing this passage is to .
A. expect people to concern about the life of koalas
B. record trip to Australia for watching koalas
C. present some basic knowledge of koalas’ life
D. introduce the ecosystem of wildlife in Australia

Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms.
Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago.
Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger.
"As new species of pests and diseases evolve and potentially the environment for them becomes more amenable at higher latitudes, the pressure on the breadbaskets of the world is going to increase."
Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species.
“It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America.”
Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
1.The purpose of Dan Bebber’s research was to find ______.
A. if farmland could be moved to colder places thanks to global warming
B. if diseases and insects harmful to crops were going towards colder areas
C. if organisms were moving to the north and south poles
D. if the number of crop pests was increasing
2.According to Dan Bebber, if crop pests keep moving towards the poles, ______.
A. it will be hard for farmers to kill them
B. the most productive farmland will produce more crops
C. the earth will not produce enough food to support the world
D. the conditions for some crops may be improved
3.Which of the following is not a threat that farmers have to face?
A. Climate change helps crop pests to adapt to new environment.
B. Foreign species are brought in by trade.
C. Invasive species doing well in warmer places might do well in America.
D. The impacts of the climate and species changes on crops are not easy to determine.
4.The underlined word “amenable” in the fourth paragraph most probably means ______.
A. agreeable B. terrible C. unfriendly D. changeable
