Skyscrapers are the symbol of Urban life.City people are used to seeing tall buildings and apartments. Farms，on the other hand,are associated with rural(农村的)life.However，there are experts who think skyscrapers should become farms to meet the increasing food needs.

By the middle of this century, some scientists suggest，almost 80% of the earth's population could live in cities. In addition，the population could increase to 9.1 billion people during that time yet the amount of　 land available for farming will be the same.If current farming practices don't change，we will need an area of new land to produce enough food for the planet.

Vertical farms, where urban farmers could grow crops in environmentally friendly skyscrapers, could be the solution. In spite of concerns over high costs, experts want to make it a reality and use these skyscrapers to grow crops.

Vertical farms would have many advantages, supporters say. Unlike traditional farming, vertical farming could be free of chemicals and diseases. Besides, crops would not suffer from problems like flooding. Finally，vertical farms would reduce the cost and negative effects of transporting food over long distances.

Some argue that although crops growing in a tall glass building would get natural sunlight during the day，it wouldn't be enough. For this reason，vertical farms would need additional light sources(来源), such as artificial light.

Another way of growing fresh food is to build urban farms on rooftops. This more practical approach may be more achievable than the idea of farms in skyscrapers, researchers suggest. Experts agree that innovative(革新的)farming practices are needed to support the need for more food at affordable costs, both to the farmer and to the consumer,but the best ideas could be yet to come.

1.What primary problem could vertical farming settle？

A. Poor state of rural life.

B. Shortage of food supply.

C. High cost for transporting crops.

D. Environmental pollution by transitional farmings

2.What is the advantage of vertical farming?

A. It can produce organic food.

B. It requires little care.

C. It can benefit transport industry.

D. It needs very low cost.

3.What is a big challenge to make vertical farming a reality?

A. Farmable land. B. Crop diseases

C. Light sources. D. Climate conditions.

4.What can be the best title of the test?

A. Future Food Needs

B. Symbol of Urban Life

C. Farming on Rooftops

D. Farms of the Future

Birds in cities are damaging their health by trying to sing above the noise of urban life．

New research shows that male birds are trying to compete against traffic and city sounds．They are now singing louder and at higher frequencies，which could harm their vocal cords．Some birds are choosing to sing at night instead of dudng the day．This makes them more open to attack and also creates stress and exhanstion．

“The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate．This could lead to inbreeding and a weak gene pool．”said Dr Sue Anne Zollinger of the University of St Andrews．

According to Zollingar,a bird group with a small geae pool might adapt less quickly to new diseases and could be wiped out．

A study of the dawn chorus found that birds in Berlin sang up to 14 decibels(分贝)louder than those in the forest．The birds sang loudest on weekday momings．

“By trying to sing over the sound of the city,birds are rising vocal injury,”said Zollinger．“All this puts the sarne strain on a bird’s vocal cords as when  ahuman need to shout to be heard—except the birds are doing it all day,every day,”she said．

“Singing under such pressure means birds have less control over the sound they produce． Their songs may lose quality and become more rough—sounding．”said Zollinger．This could make them appear less attractive to female birds．

Mark Constantine，author of The Sound Approach to Birding，said：“Birdsong is important for our quality of life and has been proved to reduce our blood pressure．When we live in the centre of large，urban areas，we get stressed and it's extremely good to have birdsong around us．The impact on humans of birdsong is massive．It harms us，as well as the birds，if their songs become louder and simpler

53．Some birds in cities now choose to sing at night time because_______．

A．they want to attract more birds of opposite sex

B．they are more likely to be discovered by their family

C．they can’t adapt to the loud noises during the daytime

D．they have to frighten their enemy away

A．Monday nights            B．Wednesday afternoons

C．Saturday Evenings         D．Friday momings

56．According to Dr Sue Anne Zollinger,birds singing louder might eventually lead to_______．

A．the harm done to man’s health

B  the dying out of a species

C．the serious damage to the bird’s vocal cords

Liverpool city council want to clear the city of fat pigeons. They say  that people are feeding the birds, which makes them fat. The pigeons get bigger because their normal diet would consist of seeds and insects, not high-fat junk food they are eating in the city centre.

The council want people to know that everyone who feeds the pigeons is responsible for the streets being so crowded with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.

Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds－known as "robops"－will sit on the roofs of buildings. They can be moved around to different locations. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.
