Article: A new report says only about half of all students in the main school systems of America's largest cities finish high school. The report notes higher rates of graduation -- over 70% --in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation's fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people. Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true _ of the number of students who leave high school before finishing. Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America's Promise Alliance. The private group aims to help children receive services they need to succeed. General Colin Powell was chairman of America's Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future. Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school.

Article: My first experience of modern city life was quite impressive. I was very curious when I arrived in London. First, I noticed so many people were on a trip in a busy way. When I first saw the machine on the underground where you are expected to feed your ticket in and have to run through moving barriers , I was completely fascinated at it. Flashing with the light, the little green man, telling you when to cross the road, was also quite interesting, and so were those street advertisements which kept changing subjects as you look. In my native place, my life is so different from people's here. I am a market gardener from Makono, a village which is led by a market-managing group. People there usually walk two hours a day to get water from a well. What's more, I am used to going, for many hours, without drinking , so it was strange to be offered cups of tea all the time here in London. In my native place, on market days, I usually walk for several hours with my basket full of fruits and vegetables on my head, carrying them to the market for sale, to earn PS1per basket. Without the produce from my garden, I could not pay for education or healthcare for my children. Gardening is not a hobby for me - it's _ . But here people are planting something only to kill their leisure time. During our visiting-time in Britain, we visited some local government agencies, schools, churches and farms in Sussex, Scotland, Yorshire, Loncolnshire and Cambridgeshire, meeting people who were of the same profession as we are. Children in Burley-in-Wharfedale, Yorkshire, prepared a special get-together to greet us and we were also asked a lot about our life which was quite fascinating to them. For example, how we make our houses out of mud and how we get our water for our daily necessities, as well as for our garden.
Question: The most disadvantage in the writer's native place should be that _ .
Options: (A) there are many market-managing groups for gardeners (B) the lack of water makes the life there even harder (C) people there like to travel about on foot for enjoyment (D) people support themselves using the garden produce
B

Article: Marriages improve after children grow up and move out,according to an academic study, which suggests an "empty nest" is not always a bad thing. Popular wisdom has it that parents' relationships may suffer once their young fly the coop, because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley, has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together. In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies, once their children reached their teenage years and finally at age 61, when almost all had "empty nests". Although not all said they were happier in general, most claimed their marriages had improved since their children had left home. Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other's company more. One of the participants in the study,which is published in the journal Psychological Science,said:"Once the kids grow up...there's some of that stress removed...that responsibility removed,so things are a little more relaxed." Psychologist Sara Gorchoff,who carried out the investigation,said: "The takehome message for couples with young children is 'hang in there'." Her coauthor Oliver John added:"Don't wait until your kids leave home to schedule quality time with your partner." However, Dr Dorothy Rowe,from the British Psychological Society,said the effects of living in an "empty nest" will depend on the parents' relationship with their children."If you're just waiting for them to leave home so you can get on with your life,then of course you'll be pleased to see them go," she said, "But if you've built your life around your children you'll be terribly lonely.For some parents,their world falls apart when their children leave."
