26、 Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.
How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.
“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.
Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.

27、When she was 2 years old, Blosberg’s dad was diagnosed with a serious illness that disrupts the central nervous system — MS. But 13 years later, her eyes started moving around rapidly and uncontrollably and her skin became extremely sensitive. The symptoms she was experiencing felt “familiar” because they really looked a lot like the things that her dad was experiencing.
After Blosberg was officially diagnosed with MS in 2011, she realized she needed to connect with other teenagers who had MS and truly understood what she was going through. “I knew there had to be other kids out there, and I wanted to connect with them,” she says. Blosberg then decided to create a Facebook page for young people with MS and obtained the help of the National MS Society. “If you find anyone else young, let me know,” Blosberg recalls saying to the organization. “I want to talk to them. I want them to know that they’re not alone.”
MS is often considered “an adult illness”. Blosberg’s Facebook page was her way of bringing young people with MS together. But she decided to take things one step further by founding a nonprofit, the MS Monkey, which supports children and teenagers who have been diagnosed with the illness. Through it all, Blosberg says her entire family has been proud of her — especially her father. “He knows what it’s like to live with MS,” she shares. “He’s my role model, though. I grew up watching him live with MS and not letting MS get in the way.”

29、 About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green — a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【1】The passage is mainly about _______.
A. color and its surprising effects B. women being luckier than men
C. danger caused by color blindness D. color blindness
【2】According to the passage, with the help of the “cones”, we can _______.
A. tell different shapes B. see in a weak light
C. kill mosquitoes D. tell orange from yellow
【3】Why do some people say it is safer to be driven by women?
A. Women are more careful.
B. There are fewer color-blind women
C. Women are fonder of driving than men.
D. Women are weaker but quicker in thinking.
【4】Which of the statements about the color-blind is true?
A. All of them don’t have the same problem in recognizing color.
B. None of them can see deep red.
C. None of them can tell the difference between blue and green.
D. All of them see everything in shades of green.

A Bad Idea
Think you can walk, dive, take phone calls, e-mail and listen to music at the same time? Well, New York's new law says you can't. And you'll be 【1】 $S100 if you do it on a New York City street.
The law went into force last month, following research and a(n) 【2】number of accidents that involved people using electronic gadgets when crossing the street.
Who's to【3】 ? Scientists say that our multitasking abilities are limited.
"We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist in Tennessee. “But a major limitation is the inability to【4】on two things at once".
The young people are often considered the great multitaskers. However, an Oxford University research suggests this idea is open to question. A group of 18-to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate【5】into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or a(n) 【6】message, the older group matched the younger group in speed and 【7】.
It is difficult to measure the productivity【8】by multitaskers. But it is probably a lot. Jonathan Spire, chief analyst at Basex. a business-research firm, estimates the cost of interruptions to the American economy at nearly $650 billion a year.
The【9】is based on surveys with office workers. The surveys conclude that 28 percent of the workers' time was spent on interruptions and【10】time before they returned to their main tasks.
