The future of agriculture must achieve several goals at the same time.
First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels (生物燃料). We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture’s impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world’s poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the under-nourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our high-efficiency, globalized world has many benefits, but it is vulnerable (易受伤的) to destruction, whether from droughts, diseases or sudden price rises. We must start building better food systems to better keep us away from future shocks.
Currently, there are two models of agriculture: local and organic agriculture vs. globalized and industrialized agriculture. Each has been strongly supported and severely criticized, but neither of these models, standing alone, can fully meet our needs.
Organic agriculture teaches us important lessons about soils, nutrition and pest management. Unfortunately, organic food provides less than 1% of the world’s calories, mostly to the wealthy. It is hard to imagine organic farming developing to feed 9 billion. Globalized and industrialized agriculture has benefits of high output and low labor demands. Without it, billions of people would have starved. However, it has come with enormous environmental and social costs, which cannot be sustained.
Rather than voting for just one solution, we need a third way to solve the crisis. Let’s take ideas from both sides, creating new, hybrid solutions that increase production, save resources and build a more sustainable agriculture.
There are many promising avenues to pursue. A new “third way” for agriculture is not only possible but also necessary. Our problems are huge, and they will require everyone at the table, working together toward solutions.

Recently, online high schools in America have sparked (激发) a debate about whether or not taxpayers’ money should be used to support online education. Online schools receive the same amount of funding as all other public schools, even though they don’t have to pay for rent or school equipment. States should use their educational funds to improve education at real schools, not to support online programs.
Some students only use online classes to supplement their school work. They benefit from the social experience of a traditional high school, while still taking online courses.
However, about 90 thousand students in America receive their education only from online schools. 50 thousand of these students take courses at Florida Virtual School, the largest online school in the country. While this method of schooling helps students who live in remote regions, most school systems are upset that they are losing more students each year to these online programs.
Although online learning allows children to work at their own pace, these online schools have only one teacher per several hundred students. Often, teachers can’t give struggling students the help they need as they are unable to talk face-to-face with them, to find exactly what they’re having difficulty with.
Additionally, even though online schooling accommodates (顾及) students who live in more remote states, students in online programs may suffer in social situations because they will not learn valuable communication skills from their schooling. Similar to students who are home schooled, those who take only online classes won’t learn social etiquette (礼节), and will be treated differently by their peers.
Online schooling might be useful for places where there are not enough students for a real school, such as agricultural regions, but states should only spend taxpayers’ money on online schools in extreme cases.
【小题1】What is the passage mainly about?

A．Whether students should study at online schools.

D．could not become fully developed

【小题4】 What is the author’s attitude?

A．Taxpayers should not pay for online schools at all.

B．Taxpayers should pay more for online schools than real schools.

C．Taxpayers’ money should be spent on online schools conditionally.

D．Taxpayers should support online schools in different ways.

A study involving 8,500 teenagers from all social backgrounds found that most of them are ignorant when it comes to money. The findings, the first in a series of reports from NatWest that has started a five-year research project into teenagers and money, are particularly worrying as this generation of young people is likely to be burdened with greater debts than any before.
University tuition feesare currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.
In the research, the teenagers were presented with the terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £10.000. Average debts for graduates are £12,363.
Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they are to become responsible, forward-planning adults who manage their finances confidently and effectively."
Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweather, aged 15, from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.
【小题1】Which of the following can be found from the five-year research project?

A．Students understand personal finances differently.

【小题2】The phrase "to raise the ceiling" in paragraph 2 probably means "______".

A．to raise the student loans	B．to improve the school facilities
C．to increase the upper limit of the tuition	D．to lift the school building roofs

【小题3】According to Stephen Moir, students _______.

A．are too young to be exposed to financial issues

B．should learn to manage their finances well

C．should maintain a positive attitude when facing loans

D．benefit a lot from lessons on personal finance

【小题4】What can we learn from the passage?

A．Many British teenagers do not know money matters well

B．Teenagers in Britain are heavily burdened with debts.

C．Financial planning is a required course at college.

D．Young people should become responsible adults.

ALBANY，New York—Students who rely on working at night to improve their
grades might want to sleep on that strategy: A new survey in the US says those who never study all night have slightly higher grades than those who do.
A survey of 120 students at St.Lawrence University found that students who had never pulled an allnighter on average had higher grades than those who had. The survey found those who did not study through the night had a grade point average of 3.2 compared to 2.95 for those who did.
The study, by assistant professor of psychology Pamela Thacher, is to be included in the January issue of Behavioral Sleep Medicine.
“It's not a big difference，but it's pretty striking, ” Thacher said, “I am primarily a sleep researcher and I know nobody thinks clearly at 4∶00 in the morning. You think you can do，but you can't.”
Many college students, of course, have inadequate or irregular sleep, for reasons ranging from excessive caffeine to poor time management.
“A lot of students were under the impression that allnighters were a very useful tool for accomplishing work, and that caffeine intake was very useful in meeting deadlines and stuff like that, ”said Mr Chatani, who had a 3.4 grade point average last term.
Dr Howard Weiss, a physician at St.Peter's Sleep Center in Albany, said the study results made sense.
“Certainly that data is out there showing that short sleep duration absolutely interferes with concentration and performance on objective testing, ”he said.
“Some night owls do get good grades, of course，which may be explained by circadian (昼夜节律的，生理节奏的) rhythms, ”Weiss said, “Some people have different 24hour body clocks from others, and may do better depending on classes and testing time.”
63.The purpose of the passage is to tell us 　　　　
A. the bad effects of pulling an allnighter
B. pulling an allnighter leads to sleep problems
C. Thacher's doubt about allnighters
D. allnighters influence students' grades
64. According to Thacher's study，around 4 o'clock in the morning is a time when 　　　　.
A. one can think more clearly
B. one has his/her best memory
C. one can't learn efficiently
D. one's brain falls into a period of deep sleep
65.What can we know from Dr Howard Weiss' words？
A. Thacher's study is not convincing enough.
B. He believes in Thacher's study.
C. Thacher's study makes no sense.
D. Thacher should take exceptions into consideration.

There is an old saying in English： "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.
Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing； it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which tolerated the pain for the longest time was 'the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins （内啡肽） in the brain. These are natural chemicals which diminish both stress and pain.
There is also some evidence to suggest that laughter helps the body's immune(免疫的)system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group served as the control group - in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists （精神病学家） in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

D．has no effect on the body

【小题2】Doctors have found that laughter_______________________.
