Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer， saying studies showed a clear link. "Our suggestion is for people to increase their intake， through diet or a vitamin supplement，" Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies， including several large long-term ones， on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. "There's nothing that has this ability to prevent cancer，" he said， urging governments and public health officials to do more to fortify foods with vitamin D.Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk， as well as in some fortified orange juice， yogurt and cheeses， usually at around 100 international units （IU） a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day， Garland said， adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas， which receive less vitamin D from sunshine.
African Americans， who don't produce as much of the vitamin because of their skin colour， could also benefit significantly from a higher intake， the authors said. According to the passage， people are advised to take more Vitamin D because_________.
| A．it is nutritious |
| B．it can‘t harm people’s health |
| C．it is not taken enough every day |
| D．it can lower cancer risk |
Which of the following can not help people get more Vitamin D？
| A．Have more meat | B．Have some sunshine |
| C．Have a vitamin supplement | D．Have more fortified cheese |
Who can Garland probably be？
| A．A scientist | B．A health researcher |
| C．A doctor | D．A public health official |
Which of the following food can lower people‘s chance of getting cancer？
| A．Fortified orange juice | B．Milk |
| C．Fortified yogurt | D．All of the above |
People from which area should take more Vitamin D according to the passage？
| A．Asian people | B．American people |

Students who say they never or hardly ever used dictionaries often speak English well but usually write poorly, because they make many mistakes.
The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.
The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables (音节), they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionary.

Most people seem to be passive at work. They do what they are told to do, and they don’t do what they are not told to do. In the end, one thing results: unmotivated (不积极的) people.
We’re employed to think. In fact, no matter how many times our bosses disagree with us, it is our responsibility to think for the company. There are lots of times when I disagree with my boss, and sometimes we even end up having arguments; however, I still offer my suggestions whenever I don’t agree.
Spending more time thinking also helps us to be more efficient (高效的) and helps to reduce our chances of frustration (挫败). Before I do something, I usually need some time to think about it to make sure that what I’m doing makes sense. This can be as long as a few days when a project is big, or as short as only a few seconds for a simple task. After thinking about a project, it sometimes becomes clear that a simple task could achieve the same result. In those cases, not only did I save myself from possible frustration, but I also felt happy and satisfied that I saved valuable resources for my company.
With so many people not taking time to think, it’s no wonder that many people are unmotivated. Today, I encourage you to think things over whenever you have a chance. At first, it might take a while, but once it becomes a habit, you will feel more motivated as you will be more valuable to the company.
73. It is suggested in the passage that people should _____.
A. stop arguing with their bosses B. seize every chance they meet
C. present views to their companies D. avoid big projects
74. According to the passage, spending more time thinking _________.
A. is a waste of time and resourcesB. can help people understand what others do
C. can help people impress their companies D. is a good way to improve efficiency
75. The author wrote this passage to ________.
A. persuade people to do what they are not told to do
B. encourage people to be more motivated
C. show people how to give different opinions
D. tell people how to form good thinking habits
While staying with a family, I found their teenage son, David, aged 16, didn’t share his true feelings with his parents. If his parents were present when I asked him how he felt about things, he would look down or away or say something unrelated such as, "Today, I will go out. "or "Okay, I guess. "However, when we were alone he would open up and tell me how he felt. For example, while sitting at the dinner table, I asked him how he felt about his history class and the teacher. He thought for a moment but said nothing. I thought he was afraid to answer in front of his parents, so later I asked him again in private. He said, "On a scale (级别) of 0-10, it is a big fat zero. He is the most boring teacher I have ever had. "I asked him why he didn’t tell me this earlier. He said it was because his parents didn’t want to hear that. They just wanted to hear that everything was wonderful and they always told him to stop complaining.
This made me think a lot. My belief is that children are born with the desire to share feelings. I also believe they are born with perfect emotional honesty. Unfortunately, such valuable things are disappearing gradually. It really is a great loss, which I believe, will negatively affect both the children’s ability to know about themselves and their success in future relationships.
I see the situation as a missed opportunity, an opportunity for parents to get closer to their children, an opportunity to understand their children and to help them feel understood; however, communication gaps (分歧) have been made. Parents are more interested in "correcting" their children’s ways of expressing themselves than in getting to know their children.

A. David is not good at talking B. David likes showing his true feelings in public

72. The author thinks that parents should ____________.
A. stop complaining about their children
B. try to understand their children’s true feelings
C. find more ways to communicate with their children
D. correct their children’s ways of communication
A 14-year-old girl was attacked by a grey bear while competing in a bike race. She managed to whisper the word "bear" to her rescuer. The girl suffered serious head, neck and leg wounds and is now in a dangerous condition in hospital.

Armed police trekked (长途跋涉) 3km with doctors to pick up the girl. Animal expert Rick Sinnott said something must be done as soon as possible to prevent the bear from attacking people again. "It had to be extremely terrifying, "he said. Mr. Sinnott told the Anchorage Daily News that the bear could have been a mother. It hurt two runners on a nearby path two weeks ago.

Our eating habits are very important for good health and a strong body. There are times when most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite (食欲). It is important for us to eat our meals at the same time each day. When we feel hungry, it is a sign that our body needs food. When we feel angry or excited, we may not want to eat. A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not eat the bread, it showed that he was telling lies. Although this seems very strange and rather foolish, it is indeed a very good way of finding out the fact. A man who is worrying about something has difficulty in eating anything dry. Because he is worrying, he loses his appetite and does not want to eat.
