Passage 2

“Sleep is a behavior and, like all behaviors, it differs greatly among people,” explains Dr. Carol Landis. “The greatest differences occur in the timing of sleep and the amount of sleep-the factors which are most important in determining whether you will wake up feeling rested.”

Research has found that people sleep better at different times during their daily cycle. For example, some people function better if they go to sleep early and rise early, while others feel more rested if they stay up late and sleep in. “Many people don’t pay attention to the timing of their sleep,” Landis notes. “Yet delaying or altering the time you go to sleep can have a major impact on how you feel when you wake up.”

The amount of sleep the average adult needs each night also differs. Some

people may be fine with six hours of sleep, while others need up to nine hours per night. Landis points out that those who follow a regular sleep schedule tend to function better on fewer hours, but she adds that most adults need at least six hours of sleep each night.

“A person’s sleeping patterns aren’t set in concrete,” Landis stresses.

Gradually altering the timing of sleep can help change sleep patterns. An“evening person” who needs to get to work early in the morning can try upping the time they go to bed by 30 minutes every few days. Within a few weeks, this slow adjustment will help“reset”the body clock.

In addition to maintaining a regular daily sleep schedule, Landis offers the

following tips on having a good sleep:

  • Avoid cigarettes, caffeinated (含咖啡因的) drinks and food such as chocolate in the late afternoon and evening.
  • Avoid alcohol in the evening. This can cause a person to wake up a few hours into sleep and interrupt sleep patterns.
  • Finish exercising at least two hours before going to sleep. Exercise increases body temperatures and makes it more difficult to easily fall asleep.
  •  Don’t sleep in a warm environment. A drop in a person’s body temperature is important at the beginning of deep sleep. People who sleep in a well-heated room or use an electric blanket may not sleep as soundly.
  •  Catch up on missed sleep when you have the opportunity. To reduce your sleep debt, try taking a 30-minute nap (小睡) during the day before 4 p.m. or sleeping in on weekends when you have a chance.

 Which of the following is true according to Dr. Landis?

  • A. People with longer sleep feel more rested.
  • B. People tend to have similar sleep schedules.
  • C. Changing sleep habits won’t affect people’s body clock.
  • D. Changing the time for sleep can affect the quality of people’s sleep.

71

Passage 1

People who do not get enough vitamin A in their food may develop night blindness. But in the developing countries, especially the countries in Africa, a lack of vitamin A causes much more serious harm to children. The World Health Organization reports that the lack of vitamin A leads to as many as two hundred fifty thousand child deaths every year.

Sweet potatoes with orange flesh have high levels of vitamin A. Experts say

orange sweet potatoes could help solve the lack of vitamin A in Africa. But, first, more people there will need to be persuaded to eat them. Jan Low with the International Potato Center, a research organization, says the sweet potato needs a better image in Africa. She said, “We do have an image problem with sweet potato in general in Africa. Most of the local people refuse to grow sweet potatoes. It is seen as a food of the poor.” Ms. Low explains that sweet potatoes are mainly grown by poor women to feed their families in case other crops fail.

The sweet potatoes commonly grown in Africa have white or yellow flesh. But,more importantly, they are low in vitamin A. Thus, Jan Low and her partners managed to tell the African people that orange sweet potatoes had high levels of vitamin A. They made use of the radio to spread the message that orange sweet potato is good to human health. They said that orange sweet potatoes were able to help you fight diseases, make you strong, clear your skin and make you look healthy.

In areas without radio, they spread the message through singing, dancing and storytelling in local theaters. And everywhere they went, they wore orange T-shirts and hats. They even drove orange vehicles. Jan Low says the color of the tuber (植物的块茎) made it easier to gain public attention.

Dan Gustafson works for the United Nations Food and Agriculture Organization. He pays attention to efforts in the past to increase the popularity of other nutritious crops. He says most of these efforts failed because organizers did not consider what people wanted to eat. But Mr. Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa. For one thing, except for the color, the orange sweet potato is similar to what people already use. He is confident about the popularity of orange sweet potato in Africa and the improvement of people’s health condition there.

  • A. they are very ugly in shape and color
  • B. they are difficult to grow
  • C. they are regarded as the food of the poor
  • D. they do great harm to the land
