巧学巧练系列答案Steve Jobs, co-founder and former CEO of US technology giant Apple, has died at the age of 56. Mr Jobs had announced he was suffering from cancer in 2004. Apple said he had been "the source of countless innovations（创新）that enrich and improve all of our lives" and had made the world "immeasurably（无法衡量的）better".
Tributes(赞美之辞) have been made by technology company bosses and world leaders, with US President Barack Obama saying the world had "lost a visionary（有远见卓识的人）". "Steve was among the greatest of American innovators —— brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it," said Mr Obama.
A statement from Mr Jobs's family said they were with him when he died peacefully on Wednesday. "In his public life, Steve was known as a visionary; in his private life, he loved his family deeply," they said, requesting privacy and thanking those who had "shared their wishes and prayers" during his final year.
Apple said the company had "lost a visionary and creative genius(天才) and the world have lost an amazing human being". Tim Cook, who was made Apple's CEO after Mr Jobs stood down in August, said his predecessor had left behind "a company that only he could have built, and his spirit will forever be the foundation of Apple". Flags are being flown at half mast outside the Apple headquarters（总部） in Cupertino, California, while fans of the company have left tributes outside Apple shops around the world.
The heads of other leading technology companies have also paid tribute, including Microsoft boss Bill Gates, who said "For those of us lucky enough to get to work with him, it's been a great honour. I will miss Steve very much."
Facebook founder Mark Zuckerberg thanks Mr Jobs for "showing that what you build can change the world" while Sony Corp president and CEO Howard Stringer said: "The digital age has lost its leading light." South Korea's Samsung, which is involved in a case with Apple over patents(专利), admired Mr Jobs for his "Completely new and different changes to the IT industry".

Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.
One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.
【小题1】GM foods ________.
| A．are a quick way to produce food |
| B．grow in the wild |
| C．are safe |
| D．are grown only in rich countries |
| A．They are not useful. |
| B．They are not helpful. |
| C．They are not natural. |
| D．They are not cheap. |
| A．GM foods will disappear one day in the future |
| B．GM foods will not disappear in the future |
| C．people will not be interested in GM foods |
| D．people will have to stop using GM foods |
Nearly all our food comes from the soil（土地）. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter（粪）from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers（化肥）are also very useful. The same crop（庄稼）should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
【小题1】Which of the following is true?
| A．All our food comes from the soil. |
| B．Most of our food comes from soil. |
| C．None of our food comes from the soil. |
| D．All our food comes from animals. |
| A．Leaves, plants, grass and waste live on each other. |
| B．There would be no animals without meat. |
| C．There would be no plants without animals. |
| D．People, animals, plants and soil live on each other |
| A．Chemical fertilizers. | B．Plants and grass. |
| C．Animals’ waste. | D．Different crops. |
| A．Because we can keep the soil rich this way. |
| B．Because we don’t have enough land. |
| C．Because we want to have a different food. |
| D．Because we do this as a habit（习惯）. |

The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must try to control the growth of population at the same time.
【小题1】Our world is becoming much smaller .
| A．because the earth is being polluted day and night |
| B．because science is developing |
| C．because of the rise in population |
| D．because the earth is blown away by the wind every year |
| A．much easier than | B．as easy as |
| C．as hard as | D．much harder than |
| A．water pollution | B．air pollution |
| C．noise pollution | D．rubbish |
| A．CO2 | B．H2O | C．SO2 | D．CO |
| A．it’s bad to all living things in the world |
| B．it makes much noise |
| C．it has made our rivers and lakes dirty |
| D．it makes us become angry more easily |
Rivers are one of our most important natural resources(资源). Many of the world’s great cities are located on rivers, and almost every country has at least one river running through it that plays an important part in the lives of its people.
Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great, but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeastern Asia. The greatest of all for navigation（航海）, however, is the Amazon in Brazil（巴西）. It is so wide and so deep that large ships can go about two thousand miles up it.
Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun. In order to increase the supply(供给) of water for crops, engineers sometimes build a dam (大坝)across a river and let a lake form behind the dam. Then people can use the water not only to irrigate(灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located on rivers often cause problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of these natural resources.

| B．making electricity |
| C．washing clothes |
| D．irrigation and the production of electricity |
| A．people’s drinking water too much |
| B．people’s swimming in the river too much |
| C．chemicals and other materials |
| D．people’s building a dam across a river |
| A．The Importance of Rivers | B．Rivers in Cities |
| C．Transportation | D．Natural Resources |
