Recently American researchers suggested 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 (增强) 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 particularly 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.The underlined word in the first paragraph probably means _____.
| A．income | B．digest | C．drown | D．uptake |
Who can Garland probably be?
| A．A public health official | B．A scientist |
| C． A health researcher | D．A doctor |

Beginning college is exciting: new ideas to explore, new challenges to be met and many decisions to be made; your future begins here.
However, you will find college life is different from your previous school environment. Many of us can be easily overwhelmed by the details of running a well-balanced life. While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you.
The following you may find of use about life on campus:
·Plan well. There are so many new things to do at a new college or university. Give yourself time to make new friends and became familiar with the campus, but don’t forget why you are there. Give some time for social activities and manage your time wisely.
·If you don’t have a “system” for planning your time now (like a day timer a computer data book). get one. Most of all, don’t depend on your memory.
·Don’t miss the guidelines. The restrictions, rules and regulations of all kinds can usually be found in your student’s handbook. Consider them well-balanced food for thought. What dates are important? What pieces of paper need to be handed in? What can / can’t you do in your student residence（住处）? Who has the right for what? What do you need to complete to graduate?
·Write the word “STUDY” on the walls of our bedroom and bathroom, and maybe it will help to to write it on a piece of paper and stick it on the telephone, TV and the kitchen table. Consider this — you are paying thousands of dollars for your course. You pay every time you have to repeat or replace a course.
·Build your identity. This is the time for you to decide what to do and what not to do. Take as much time as you need to explore new ideas. Do not be afraid of the beyond. This is learning to make good choices.

Imagine being the only person in the Forbidden City. You could stay there all day without swarms of people crowding around.

Well, in two years time you'll be able to have such an experience, just like the former emperors used to. The only difference is that your Forbidden City fun will be online.
Thanks to new technology, a virtual tour of the Forbidden City will be available online by 2008.

"The Palace Museum is a big book; there are always places you haven't read about," said Hu Chui from the museum. There are many rooms closed for protection. But the virtual platform breaks the boundaries of time and space, meaning visitors can see whatever they want. "The interaction and games content in the virtual tour will attract more young people to understand and love our cultural heritage," added Hu.
In the virtual tour, historical figures will actually talk to visitors and answer their questions. The stories behind the buildings and treasures will also be told.

In 1879, a group of explorers made an incredible find. They discovered paintings of remarkable beauty on the walls of a cave in Spain. Some scientists believed that these paintings were created by early humans from the Stone Age, between ten and thirty thousand years ago. Other scientists and the public did not believe the claim, but over the years, it was proven correct. Our ancestors had incredible artistic talents.
Most of the cave art that has been discovered has been found in Spain and France. A smaller number of such caves are located in Italy, Portugal, Russia, and other countries. Scientists believe that many more caves will be discovered in the coming years, and are concentrating their efforts on Africa and the area between Europe and Asia. These two regions of the world were, populated first by humans.
Cave art was carved or painted on the walls and roofs of caves, usually near the entrance. The entrance area was probably chosen to take advantage of daylight and to allow many people to view the paintings. In some cases, the art appears much deeper in caves and requires artificial light.

Mark was walking home from school one day when he noticed the boy ahead of him had stumbled over something and dropped all of the books he was carrying along with two sweaters, a baseball bat, a glove and a small tape recorder. Mark knelt down and helped the boy pick up the scattered articles. Since they were going the same way, he helped to carry part of the burden. As they walked Mark discovered the boy’s name was Bill, that he loved video games, baseball and history, and that he was having lots of trouble with his other subjects and that he had just broken up with his girlfriend.
