场） to put on events to raise money for Youth-at-Risk Programs.
Last time I was there he introduced me by saying, \you use my house. It all goes back to a story about a young man who was the son of a horse trainer． When he was a senior, he was asked to write a paper about what he wanted to be when he grew up.\
“That night he wrote a seven-page paper describing his goal of owning a horse ranch someday. He put all his heart into the project and wrote about his dream in great detail. He even drew a diagram of a 200-acre ranch, showing the location of the buildings, stables and the track, and even a detailed floor plan for a 4,000-square-foot house on it.”
“The next day, he handed it in to his teacher. Two days later, he received a large red ‘F' on his paper with a note, ‘See me after class.' The boy went to see the teacher and asked why. The teacher told him there was no way for a young boy like him to do that because owning a horse ranch required much money and resources, and then added ‘If you’ll rewrite his paper with another goal, I will reconsider your grade.’”
“The boy went home and thought about it long and hard. He asked his father what to do. His father said, ‘Look, son, you have to make up your own mind on this. However, I think it’s a very important decision for you.’”
“Finally, a week later, the boy turned in the same paper without any change and stated, ‘You can keep the F, and I will never.’”
“I tell you this story because you are sitting in my 4,000-square-foot house in the middle of my 200-acre horse ranch. I still have that school paper over the fireplace.”

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
MontanaStateUniversity scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.“We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
\a weak acid, carbonic acid,\CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the PH down, and makes it more acidic.\
The seawatersamples Dore and his colleagues have analyzed confirm what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
\can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic.\

Former Irish President Mary Robinson was just making a polite conversation with anEthiopian（埃塞俄比亚的） teenager about her wedding day. The 16-year-old had alreadybeen married for a year．\'I had to dropout of school,'\Robinson said in a telephone interview．\conveyed to me the reality, \and former U．N．high commissioner forhuman rights．\life, as far as she is concerned, had more or less ended．\
Robinson said keeping girls in school was one of the most important things policymakerscould do to address the coming challenges of an ever-increasing population, predicted bythe United Nations to reach 7 billion soon．\countries are concerned about agingpopulations as is Japan, but this is much less of an issue than the huge number of peoplewhich we are going to see over the next 40 years when the population goes from 7 billion to9 billion, \．\of that increase will be in poor developing countries, sothat we have a very big challenge．\
Family planning experts worry in particular about the future population explosion insub-Saharan Africa．In May, the United Nations projected the world population wouldreach 9.3 billion in 2050 and 10.1 billion by 2100. Much of that growth will come from Africa,where the population is growing at 2.3 percent a year—more than double Asia' s 1 percentgrowth rate. If that rate stays consistent, which is not certain, Africa's population willreach 3.6 billion by 2100 from the present 1 billion．
Joel Cohen, a professor of population studies at RockefellerUniversity and ColumbiaUniversityin New York, said universal secondary education offered a way to reduce population in highbirth-rate regions. In addition to providing information about birth control, a secondaryeducation teaches women to reduce their own fertility（生育力）, improve the health of theirchildren and allows them to move from a mind-set of having many children, in the hopesthat some will survive to improving the quality of each child's life, Cohen wrote in thejournal Nature.
59. In the first paragraph, the author introduces his topic by_____． A. explaining the author's opinionsB. giving an example
C. describing the poor education system D. coming straight to the topic 60. What can we learn from the passage?
A. Robinson is happy after talking to the Ethiopian girl. B. Robinson is a successful expert in population studies. C. Robinson is worried about population growth. D. Robinson encourages female education.
61. What is Joel Cohen's view about secondary education? A. It provides basic knowledge of health. B. It improves the health of children.
C. It makes people pay more attention to education. D. It can change people's parenting ideas.
62. According to the passage, the most important way to control high population growth
is.
A. keeping girls in school B. letting girls go away from Africa C. letting young girls remain single D. keeping girls in
families

Farmers may not be able to prevent natural disasters, but they can at least try their best to reduce losses.
For example, they can plant crops that are more likely to survive extreme weather. In north-central Vietnam, people with small farms do not plant rice between September and December. Seasonal rains might destroy the rice. So instead, they plant lotus seeds on raised beds. The United Nations Food and Agriculture Organization says the lotus seeds bring a good price in local markets.
Farmers in the Philippines are showing new interest in crops like winged beans, string beans, arrowroot and cassava. The AsianDisasterPreparednessCenter says traditional crops like these can survive the fierce storms that often strike the islands.
The United Nations says some African farmers grow bambara groundnuts during long dry periods. The seeds of this drought-resistant plant can be boiled for eating or for making flour.
In some parts of the world, farmers grow vetiver grass. Researchers in Thailand wrote about vetiver in 2007 in the journal Science Asia. They noted that the grass can absorb and control the spread of harmful waste waters, like those from pig farms.
Agricultural expert and author William Rivera says vetiver resists difficult conditions. It reduces damage from heavy rains. And vetiver planted on earthen dams may strengthen them against breaks and flooding.
William Rivera also speaks approvingly of alfalfa. Its deep roots can find and take up groundwater. Those roots also help hold the soil against winds. And alfalfa can be a valuable food source for animals.
The deep and extensive roots of sunflowers make them another good candidate for resisting extreme conditions. The tall plants have brightly colored heads that provide seeds and oil.
North Dakota grows more hectares of sunflowers than any other American state. But North Dakota is better known as a top wheat producing state.
Hans Kandel works at the North Dakota State University Extension Service in Fargo. He says farmers in some parts of North Dakota plant wheat that is ready to harvest in only about one hundred days. That way it can grow before the hot, dry months of July through September.
