At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.

A.a medical treatment | B.a kind of vitamin | C.a kind of germ | D.a kind of rice |
A.spend his holiday |
B.find ways to grow better crops |

举一反三
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

LEEDS, England—A Leeds University psychology(心理学) professor is teaching a course to help dozens of Britons forgive their enemies.
“The hatred (仇恨) we hold within us is a cancer,” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become members in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight.
The course ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said. “People confuse(混淆) forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.” Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with, ”said Norman Claringbull, a senior expert on the forgiveness project.
Hart said he believes forgiveness is a skill that can be taught, as these people “want to get free of the past”.

David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
小题1:What is the passage mainly about?
A.Teens’ sleep is linked to their relationship with people around them. |
B.Lack of adequate sleep puts teens at risk of many bad consequences. |
C.Modern technology has something to do with teens’ sleep problems. |
D.It is necessary for teens to join in sports and positive social activities. |
A.Teens who feel like talking with their parents. |
B.Teens who have friends sharing their dreams. |
C.Teens who feel contented about themselves. |
D.Teens who lack a sense of security at school. |
A.a comparison | B.an introduction | C.a conclusion | D.an addition |
A.continue their broken marriage |
B.allow children to decide when to sleep |
C.limit teens’ using new technology |
D.force teens to have 10 hours’ sleep daily |
