Goats are being hired to do the work of people near SanDiego. The fires that occurred in Hillborbough four years ago destroyed thirty homes, most of which have been rebuilt. While people were rebuilding the homes, the grasses and bushes were growing back. The area is now so overgrown in bushes that there is again a major danger of fire.

The city council asked for offers to remove the bushes. The lowest bid they received was $50,000-----and that was if the city provided breakfast and lunch for the workers for thr six weeks it would take to clear the overgrown area. The city only wanted to give unlimited coffee and a piece of bread a day for each person. When that offer was rejected, the city asked for help on its website.

A sheepherder(养绵羊的人) in Montanta and a goatherder(养山羊的人) in San Bernardino read about the city’s plight (困境)while surfing the Web on their laptops. They both offered to do the job for $25,000. The council chosed the goatherder because he lived closer. When he was told that the city dump(垃圾场) was overflowing , the gotherder said, “No problem. My goats will eat everything in your dump, except the car engines, of course.” So ,for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goatherder and his “family” back every three years. The goatherder said that he would probably visit San Diego while his goats were in the dump. “I want to go there by plane, I just hope we don’t crash. My goats will miss me a lot.” He said.

American farmers are raising five percent more goats for meat these days.

  Goat meat is high in protein(蛋白质)and lower in unhealthy fat than many other meats.Even so,the industry is small compared to chicken,beef and pork. But immigration has brought more of a taste for goat to America from all over the world.

  Experts from the University of Illinois offer some questions for people to consider if they are thinking about raising goats.

  First of all,do you understand that there always has to be someone to care for the goats?

  ◆How much land do you have available? And how good is it? Poor ground may support two to four goats on half a hectare.Better grassland can support six to eight. If goats and cattle share the land,two goats can be added for each cow. The goats will eat weeds and other plants that cattle do not like.

  ◆Do you have buildings for the number of female goats you plan to keep during winter? An open,cold,dry barn is better than a closed,warm barn where the air is wet.

  ◆Do you have the equipment to clean barns(畜棚) and to harvest hay(草料) to feed your goats? Or will you get someone else to do it,or buy the hay?

  The experts say a profitable business in goat meat may take three to five years to establish.And, of course, there are no guarantees .

On which section of a newspaper will this passage appear?

The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An F.D.A. official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代) are safe to eat as well. But research on cloned sheep is limited. So the F.D.A. proposes that sheep clones not be used for human food.

The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents.

The agency says it must receive comments by April second. The F.D.A. seemed ready to act several years ago, but an advisory committee called for more research.

For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

Clones are still rare. They cost a lot and are difficult to produce.

The F.D.A. says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.

Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.

Cloning differs from genetic engineering. A cell taken from a so-called donor animals is grown into an embryo(胚胎)in the laboratory. Next, the embryo is placed into the uterus(子宫)of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

From the passage we know that               .

A. foods from cloned animals are popular in America

B. cloned adult animals are safe to eat except sheep.

C. cloned animals will be easy to produce

D. most foods from cloning is expected to take place of other foods

The main purpose of the text is to               .

A. tell a interesting story     B. give some advice on foods

C. give a report            D. compare different opinions

Who believe that foods from cloning are safe to eat?

A. Most Americans     B. An advisory committee

C. Critics             D. The F.D.A.

It can be inferred from the last paragraph that         .

A. cloning has much in common with genetic

B. not every cell taken from a donor animal can grow into a genetic copy

C. the donor animal should be a female one

D. cloned animals grow faster than normal ones

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
