Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix (混合) them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses (损失) from diseases.Which of the following best gives the main idea of the passage?
| A．Computer helps find the best program for mixing plants. |
| B．Computer helps produce more crops. |
| C．Computer helps protect against insects and diseases. |
| D．Computer helps grow different plants. |
According to the passage, to get the best result, one needs to choose carefully ________.
| A．the kinds of crops to be planted together |
| B．the way for different crops to be mixed |
| C．both A and B |
| D．either A or B |
It seems the new computer program can NOT tell us ________.
| A．whether we should grow cotton and tomato together |
| B．how we should plant cotton and tomato together |
| C．what will happen if we grow potato, instead of tomato, together with cotton |

Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.
No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.
There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier.

The oldest and most common source (来源) of renewable energy known to man, biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere —- from trees and grasses to agricultural and city —- life wastes —-biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide, because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun’s energy. In this way, biomass serves as a sort of natural battery(电池) for storing the sun’s energy. As long as biomass is produced continuously —-with only as much grown as is used— the “battery” lasts forever.
According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008—-although the numbers aren’t all in yet—-wind power probably took over first place because of the rapid development of wind farms across the country.
Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner’s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.Why is biomass considered as “a sort of natural battery”?
| A．It burns simply plant matter. |
| B．It stores the energy from the sun. |
| C．It keeps producing electricity. |
| D．It produces zero carbon dioxide. |
We learn from the text that in 2008 ______.
| A．0.5~0.9 of power supply came from biomass |
| B．biomass might become the main energy source |
| C．there was a rapid growth of electricity production |
| D．Wind power would be the leader of renewable energy. |
Why does the author encourage power plants to use biomass?
| A．To save money. |
| B．To prevent the waste of energy. |
| C．To reduce pollution. |
| D．To increase production safety. |
Where does the text probably come from?
| A．A book review. | B．A business report. |
| C．A research plan. | D．A science magazine |
The biggest threat to the future of Oxfordshire’s economy is transport.
That is the key finding of a major new report which interviewed more than 120 county companies. The results show 76 percent of the company owners and directors believe traffic jams and the quality of transport are affecting their business.
More than 30 percent say this is costing them dearly in the form of extra fuel(燃料) costs, while some say the situation of being stuck in jams on key roads such as the A34 and A40 every day is making it harder to employ workers.
But lack of safer cycling plans is encouraging 72 percent of people to continue to go to work by car.
The report has led the government to try to work out a solution to the situation on the county’s crowded roads.
Nicola Blackwood, an official of Oxfordshire, recently brought transport minister Stephen Hammond to the county and said he became stuck in a traffic jam on the A34.
As a result, he has promised that he will aim to look at entire roads, rather than individual projects such as improving junctions (交叉路口).
Ms Blackwood said: “If we are able to achieve anything like our economic growth, we need to solve the problems that not only affect the new companies but also the growth of existing local businesses. What I want to see most of all is the quick production of a plan to solve the problem of the A34.”
John Cardy, co-founder of Garden Games, said he had considered moving his business from a farm in Garford to Witney but traffic fears had made him reconsider. He added: “Most of our employees were not prepared to use the A40 which is always crowded.”According to the report, _____.
| A．the A34 and A40 are the most crowded roads |
| B．more and more workers are losing their jobs |
| C．companies spend more on fuel than before |
| D．there is a serious lack of fuel |

According to Ms Blackwood, what’s the most important thing to do?
| A．To solve the problem of heavy traffic. |
| B．To limit the growth of new businesses. |

The Flat World and Education, by Linda Darling -Hammond
While scores on the tests required by “No Child Left Behind” have steadily (平稳地) risen, America’s students are always falling behind on international testing measures. Why? According to Stanford education professor Darling-Hammond, it’s because U.S. schools, “designed at the turn of the last century,” are in need of a complete change.
