Compared to adults, children seem to be moving constantly. So it's no surprise that most parents who are quizzed about their child's physical activity level describe their children as fairly active. But a new study of nearly 2000 British school children suggests that many parents overestimate the amount of physical activity their children are really getting.
The researchers equipped 1892 British school children, ages 9 and 10, with accelerometers that measure all physical activity during a given time period. The research,known as the Speedy study collected the exercise data from children at 92 schools in Norfolk,England, between April and July 2007.
A child was regarded inactive if he or she recorded less than an hour a day of physical activity. Although the majority of children studied were getting enough physical activity, a_sizable_minority_of_children_were_not. Overall,39 percent of girls and 18 percent of boys studied were getting less than an hour of physical activity each day.
But if you asked the parents of the inactive children to describe their child's activity level,the vast majority—80 percent—described their children as fairly or very physically active, according to the findings published in the American Journal of Preventive Medicine. Interestingly, the children themselves had more awareness about their lack of physical activity. Overall, 40 percent of children overestimated their physical activity.
But it wasn't the parents of overweight children who were most likely to guess wrong about physical activity levels. The parents who were most out of touch about their child's physical fitness were more likely to have children who were slim. Parents of girls were also more likely to overestimate physical activity. The researchers noted that parents should be educated about the importance of physical activity for children even if the child is not overweight.
“Parents of slim children appear to assume that their children are adequately active.”the study authors reported. “Increasing awareness regarding health benefits of physical activity beyond weight control might help have a correct idea of physical activity levels and encourage behavior change.”
60.According to the Speedy study,what kind of children can be judged physically inactive?
A. Slim children.
B. Children with less than an hour a day of physical activity.
C. Overweight children.
D. Children out of touch with their parents for a long time.
61.What does the writer probably mean by saying “a sizable minority of children were not”in Paragraph 3?
A. The amount of children's physical activity is far from the writer's satisfaction.
B. Only a small number of children were not getting enough physical activity.
C. A small number of children didn't overestimate their physical activity.
D. The minority of children were not studied at all.
62.The passage is intended to________.
A. encourage parents to fairly judge their children's physical activity levels
B. persuade parents to keep an eye on their children's weight
C. urge children to wear accelerometers during exercise
D. advise parents to keep in touch with their children

Is it time to kick Russia out of the BRICs (金砖四国)? If so, it may end up sounding like a famous ball-point pen maker-BIC. An argument is being made that Goldman Sach’s famous marketing device(策略),the BRICs, should really be the BICs.
“Is Russia really worth the name BRICs?” asks Anders Aslund, senior fellow at the Peterson Institute for International Economics, in an article for Foreigh Policy. Aslund, who is also co-author with Andrew Kuchins of “The Russian Balance Sheet”, thinks the Russia of Putin and Medvedev is just not worthy of inclusion alongside Brazil, India and China in the list of future economic powerhouses. He writes:
“The country’s economic performance has fallen to such a weak level that one must ask whether it has any say at all on the global economy, compared with the other members of its group. I have just returned from Moscow, which is always dull around this season. For the last seven years, Russia has taken very few measures to improve its economy. Instead, the state has been living on oil and gas. ”
Economically, Aslund has the numbers on his side. The International Monetary Fund figures that the Russian economy will fall by 6.7 percent in 2009, while China will grow 8.5 percent and India 5.4 percent. There is less of a case for Brazil, with a fall of 0.7 percent, but it is still doing
far better than Russia.
But the BRICs are not just about economy. As is mentioned above, it is a marketing device to encourage investors to focus on the big promising players. From an investment standpoint, it could be argued that Russia is leading the BRICs. Its stock(股票)market is up 128 percent this year while around 80 percent is for the other three.
At very least, however, Russia’s economic underperformance and stock market outperfoumance does suggest it is indeed one of the group.
1.According to the passage, which country will enjoy the biggest increase in 2009?
A.China. |
B.Russia. |
C.Brazil. |
D.India. |
2.According to Aslund, Russia shouldn’t be a BRIC partly because_______.
A.Russia’s economic performance is far worse than the other three |
B.Russia’s leaders are not good at managing economy |
C.Russia has taken effective measures to improve its economy |
D.Russia will no longer attract investors from other countries |
3.From the passage we know that ________.
A.Anders Aslund is working for the Russian government |
B.Russia outperfoumed the other three countries in stock market |
C.most people disagree Russia is included in BRICs |
D.the BRICs would end up being the BICs sooner or later |
4.The author seems to ________.
A.suggest it’s time to kick Russia out of the BRICs? |
B.feel worried about the economy of the BRICs |
C.think Russia is worth being one of the group |
D.show disappointment to Russia’s economy |

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image (印象) of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team. “They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenager rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
