Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing—very, very slowly—as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that: have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.
1.Many plants may survive in deserts when___________.

Farming is moving indoors, where the sun never shines, where rainfall is irrelevant (无关的) and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature,humidity,air quality and nutrition. It could be in a New York high- rise or a complex (建筑群) in the Saudi desert. It may be an answer to the world’s food problems.
The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those – about 3 billion – are hungry or ill–fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion.
To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output.
Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating “day” and “night”, but according to the rhythm of the plant.
Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn’t to grow foods that require much space, like corn or potatoes.
Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there’s on need to transport it long distances.
1.According to the text, Gertjan Meeuws’ farming _______.
A.can be used for corn production |
B.is much like greenhouse farming |
C.is adaptable to any environment |
D.uses more water than outdoor farming |
2.What is the second paragraph mainly about ?
A.The effect of climate | B.The hungry people in cities. |
C.The world’s food problem. | D.The world’s increasing population. |
3.What is the purpose of the text ?
A.To compare traditional and indoor farming. |

C.To explain the world’s food problem. |
D.To introduce a new model of farming. |

Imagine living in a country torn by war. Or maybe you live in a place where there are few jobs and little chance to earn a living. Your family decides to move — not to another town, but to another country. You and your family have become immigrants. People are called immigrants when they move to a foreign country to make their homes.
People become immigrants for many reasons. The most common one is economic opportunities. Most immigrants are attracted to other countries by the promise of jobs, farmland, or business opportunities.
Other people become immigrants in order to get away from mistreatment or natural disasters. They are refugees. Some refugees move to avoid wars and political unrest. Others are seeking freedom to express their religious views. Still others are uprooted by disasters, such as terrible flooding or drought.
Some people have become immigrants against their will. Captured in Africa, shipped to foreign lands and forced to work as slaves, many early African immigrants to North and South America came in chains.
Except for Native Americans, all people came to the United States from someplace else. For nearly 500 years, immigrants have landed on America’s shores seeking a better life. Throughout American history, immigrants often worked low-paying, dangerous jobs that other people refused to do.
Immigrants from around the world helped shape American life. Many immigrants absorbed the customs and language common to most Americans. They also brought their own traditions, including music and foods. Over time, many of these traditions have become part of American life.
The first European immigrants to America hoped to colonize new lands. By the mid-1500s, Spaniards had ventured into Florida, California, and the American Southwest. French immigrants arrived in the early 1600s and built their first colony in Canada. The English also arrived in the early 1600s. They established 13 colonies along America’s Atlantic Coast.
In the 1700s, England became the major power in colonial North America. But many European immigrants came to live in the English colonies. They included people from Sweden, Holland, Germany, Scotland, and Ireland.
Immigrants still come to the United States seeking freedom and economic opportunities. Most new immigrants no longer come from Europe. They come mainly from Central and South America, the Caribbean, and Asia.
Today, the U.S. government keeps the number of immigrants into the country each year in check. People who sneak illegally into the United States are called illegal immigrants, who, if caught, would be sent back to their home countries.

1. | Immigrants are those who move to a foreign country to make their homes. |

The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay(黏土) or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.
The deserts of the world are not uninhabited(无人居住的). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, put them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.
【小题1】According to the passage, deserts are mostly made up of ________.
A. clay B. rock C. stones D. sand
【小题1】The underlined word “hospitable” has the meaning of being ________.

Where there are people, there are chickens. One result of a huge chicken population is a huge amount of chicken feather, which are normally burned or treated as rubbish, polluting the environment.
Ryan Robinson, a biology graduate from Imperial College London, believed there would be a different solution for this feathery waste. Therefore, along with designer Elena Dieckman, he has discovered a way to turn feathers into an insulating (绝缘的) material for buildings or a packing material for food or medicine. The pair has formed a start-up, called Aeropowder, to try and turn their invention into a commercial product. They believe the new material could have a range of uses.
“Currently feathers are mainly transformed in this country to a low-grade animal food called feather meal. Feathers can also be burned or thrown away. And these methods do not make use of their amazing natural properties (特性).” says Robinson.
It turns out that feathers are quite a wonder material. “Feathers are insulating due to their structure, which are hollow fibers,” says Robinson. Extra air in the fibers means less heat transfer. “What has been surprising is how well the material has performed, and we hope to continue to make it better and better. “The current form of Aeropowder’s material looks much more like a fattened brick of feathers. It’s flexible and light.
Aeropowder isn’t the first to try to find a further use for this very common waste product. In 2011, researchers from the University of Nebraska-Lincoln in the US suggested that chicken feathers should be used to help produce a kind of environmental plastic. The next challenge will be to find a way for this material to be made close to where the chickens are, rather than sending it far away to a processing plant.
“There is still work to be done to get our material tested with early adopters,” Robinson says. “But in the long term, we wish to become the world experts in feather-based materials.”
1.Why did Ryan begin to search for the solution for feathery waste?
A. To produce environmental plastic. B. To make big business profits.
C. To find better building materials. D. To avoid its polluting the environment.
2.What’s the advantage of the feather building material?
A. It can keep the house warm. B. It is easy to be made into bricks.
C. It is enough. D. It helps heat spread quickly.
3.Which of the following can be the best title for the text?
A. Ryan: an expert in feather-based materials
B. Feather meal: a new kind of animal food
C. Chicken feathers: a wonder material
D. Aeropowder: a new processing plant
