Many people wrongly think that cities don’t have farms and fruits and vegetables are only grown in the country. Believe it or not, there are more urban farms popping up in cities all over the world.

Alexandra Sullivan, a food systems researcher in New York, studies urban agriculture. Urban agriculture is another name for farming and gardening in a city environment. Ms. Sullivan studies everything from tiny gardens in empty lots between buildings to bigger fields that have been planted and grown. According to Ms. Sullivan, “Urban agriculture has existed since cities have, across the world.”

The number of humans living in urban areas, or cities, is increasing. The amount of people who wanted to garden in urban areas is also rising. Ms. Sullivan says, “In small gardens, on rooftops and indoors, city residents grow fruits, vegetables, grains, and herbs, and raise animals to produce milk, eggs, honey, and meat. City residents use these foods as supplements to food produced by rural agriculture.” Even though some people who live in urban areas grow crops, urban residents still need to rely on food grown in rural areas. This is because a city doesn’t have enough space to grow enough food for everyone living in it.

In New York City, urban farmers have come up with many different ways to grow their own produce, even though there isn’t a lot of room. For example, Brooklyn Grange is a farming operation that has two rooftop vegetable farms in New York City. All together, the farms are made up of 2.5 acres of rooftop space. This makes Brooklyn Grange one of the largest rooftop farming operations in the world.

Brooklyn Grange grows all kinds of things. The farming company sells its vegetables to local residents and restaurants. And because the farms are on rooftops, they are specially adapted to their urban location. They use available space that is not needed for anything else. As more urban farmers find ways to grow food in cities, urban residents will be better able to get fresher materials for their meals.

1.Which of the following is Ms. Sullivan’s opinion about urban agriculture?

A. Urban agriculture has developed recently.

B. Urban agriculture takes too much city space.

C. Urban agriculture has a history as long as cities.

D. Urban agriculture can take the place of rural agriculture.

2.For traditional agriculture, urban agriculture is a(n) ________.

A. model　　 B. addition

C. competitor　　 D. replacement

3.What can we learn about Brooklyn Grange in New York City from the text?

A. It has large farming areas.

B. It can only grow single products.

C. It produces enough food for citizens.

D. It makes use of rooftop space to grow vegetables.

4.What is the author’s opinion on the urban farms?

A. Critical.　　 B. Positive.

C. Worried.　　 D. Confused.

Campers Gene and Marie Marsden took pride in being good citizens when in the wild. While driving miles to the Green River Lakes area, they taught their children what they had learned in the bear safety handbook put out by the Bridger-Teton Forest Service.

Mr. and Mrs. Marsden did their best to keep a tidy camp. As the handbook had said to hang all food at least ten feet off the ground and four feet out from the trees, they did that and locked their food in their trailer(拖车) at night. It was already dark when they went to bed, but they perused the campsite with flashlights, making sure nothing was left out. Following the bear book’s advice, they slept a hundred yards from where they cooked their food, and kept the car near their tents, separated from the trailer, which they left up at the other camp.

The Marsdens liked having their dog Spike on guard. But on the first night, Spike would not stop barking. When Marie Marsden pulled the tent open and shone her flashlight, she saw a young bear.

They all piled into the car and drove quickly down the path, calling out of the window to Spike and abandoning the trailer. They drove to a pay phone and called a Fish and Game Department guard, who identified the bear by the white ring of the fur the Marsdens had seen around his neck. The authorities informed the Marsdens that the bear was a young male that they’d been keeping an eye on.

The next morning, the Marsdens heard helicopters circling over the mountain and wondered if it might have something to do with the bear.

After spending the night in the public campground, they drove back to their site. Wandering the area in search of clues, Marie came to a stop below a tall tree. She slapped her head and shouted, “Oh no!”

“What is it?” Gene asked.

Marie pointed at the ground where Spike’s dog food bowl lay upside down.

A week after their return home, the Marsdens read the headline in their local paper. “Bear Killed in Wind Rivers.” According to the article, the Fish and Game Department had shot the young bear because, having been rewarded for invading(侵入) a human campsite, it would likely to do so again.

The Marsdens knew they had been lucky in the encounter, yet much to their shame and sadness, they also knew that the bear had not.

1.What do we know about the Marsdens?

A. They went to the wild to watch the bear.

B. They did what the bear safety handbook had said.

C. They were the first people to trap the bear.

D. They abandoned their dog on seeing the bear.

2.The underlined work “perused” in Paragraph 2 means __________.

A. examined            B. decorated            C. found            D. clean

3.Who is mostly to blame for the bear’s death according to the writer?

A. The bear.

B. The Bridger-Teton Forest Service.

C. The Fish and Game Department.

D. The Marsdens.

4.Where does this text most probably come from?

A. A study on habits of bears in the Western mountains.

B. A scientific report on human-bear relationships.

C. A human interest article in a camping magazine.

D. A handbook on bear’s living habits.

The researchers say a person loses two months for every kilogram overweight they are— and seven years for smoking a packet of cigarettes a day.

Unusually, the Edinburgh university team found their answers by analysing differences in people’s genetic code or DNA. Finally they think it will show new ways of helping us to live longer.

The group used the genetic code of more than 600, 000 people who are taking part in a natural experiment. If someone smokes, drinks, drops out of school and is overweight, it can be difficult to identify the impact of one specific unhealthy behavior.

Instead, the researchers turned to the natural experiment. Some people carry mutations(变异) in their DNA that increase(食欲) or make them more likely to put on weight, so researchers were able to compare those programmed to eat more with those who were not. The research team also found specific mutations in human DNA that alter lifespan (寿命).

●Mutations in a gene (a set of instructions in DNA) that is involved in running the immune system could add seven months of life on average.

●People with a mutation that increased levels of bad cholesterol knocked eight months off lifespan.

●A rare mutation in a gene—APOE—linked to dementia reduced lifespan by 11 months.

●And one that made smoking more appealing cut lives by five months.

Dr Joshi says that while genes do influence lifespan, “you’ve got even more influence” through the choices you make. Dr Joshi said, “We hope to discover genes affecting lifespan to give us new information about ageing and construct treatment tor ageing.”

There are also some disease mutations that clearly affect lifespan and to destructive effect, such as the Huntington’s gene. People with Huntington’s often die in their 20s.

However, in order to follow people until the end of their lives, many of the people studied were born before 1940.

1.What is the most difficult for the researchers to find?

A. The differences in people’s genetic code.

B. The reasons why people put on weight very easily.

C. The results of many natural and massive experiments.

D. One bad behaviour’s effect on people with many bad behaviours.

2.Which of the following mutations affects lifespan most greatly?

A. One linked to controlling immune system.

B. One increasing unhealthy cholesterol.

C. One called APOE involved in dementia.

D. One making smoking more attractive.

3.What’s the meaning of Dr Joshi’s study?

A. To help stop mutations.　　 B. TO find diseases earlier.

C. TO make people live longer.　　 D. TO reduce the effects of genes.

4.Why did researchers mainly study people born before 1940?

A. To follow them until they die.　　 B. TO educate them an extra year.

C. To show they are more important.　　 D. To make them live happier.
