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 (吸入，摄入), 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 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.

The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year，but it’s always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for colored eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day.
But the holiday is more than new clothes and good things to eat. On Easter, many people go to church to celebrate Jesus’ resurrection（复活）from the dead. Most people color Ester eggs. Some people hide them. Others just eat them. But no matter what one does with Easter eggs，they are an important Easter tradition throughout the Western world. People from many different cultures celebrate Easter. In both America and Belgium, children look for Easter eggs hidden on lawns and in bushes. In America, children believe the eggs are hidden by the Easter bunny (兔子).But in Belgium, the hidden eggs are supposed to have fallen from church bells. In Bulgaria (保加利亚), red Easter eggs are lucky in churches. Bulgarian families also hit these Easter eggs together to see whose is the strongest. The winner looks forward to good fortune that year. Still dozens of other Easter traditions exist. In parts of Austria，for example，children sing from door to door and are rewarded with colorful eggs.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．
1.Which of the following is NOT done by satellites according to the passage?
A．Sending information for weather forecast
B．Taking photographs of the Earth
C．Sending TV pictures
D．Providing food for airplane pilots
2.What’s the speed the earth rotates at?
A．35,880 kilometers per hour． B．335,880 kilometers per hour
C．11,000 kilometers per hour． D．110,000 kilometers per hour
3.Why does the satellite move around the world at the same speed as the Earth rotates?
A．In order to take photographs
B．In order to stay in a certain position in the orbit
C．In order to move away from its orbit
D．In order to send television pictures．
4.What does the underlined word “This” in the 3rd paragraph refer to?
A．A satellite
B．A little rocket
C．A satellite seems to stay in the same place in the sky
D．The satellite puts the rockets in the right position．
5.Which is true of satellites?
A．A satellite usually works for about 10-12 years．
B．Every time a satellite gets broken，it is brought back to the Earth to be repaired．
C．A broken satellite is never left in space
D．They often crash into each other．

In the doorway of my home, I looked closely at my 23-year-old son, Daniel. In a few hours he would be flying to France to 36 a different life. It was a transitional（过渡的）time in Daniel's life. I wanted to 37 him some words of significance. But nothing came from my lips, and this was not the 38 time I had let such moments pass.
When Daniel was five, I took him to the bus stop on his first day of kindergarten. He asked, “What is it going to be like, Dad? Can I do it?” Then he walked 39 the steps of the bus and disappeared inside. The bus drove away and I said nothing. A decade later, a similar 40 played itself out. I drove him to college. As I started to leave, I tried to think of something to say to give him 41 and confidence as he started this new stage of life. Again, words 42 me.
Now, as I stood before him, I thought of those 43 opportunities. How many times have I let such moments 44 ? I don't find a quiet moment to tell him what they have 45 to me. Or what he might 46 to face in the years ahead. Maybe I thought it was not necessary to say anything.
What does it matter in the course of a lifetime if a father never tells a son what he really thinks of him? 47 as I stood before Daniel, I knew that it did matter. My father and I loved each other. Yet, I always 48 never hearing him put his 49 into words. Now I could feel my palms sweat and my throat tighten. Why is it so 50 to tell a son something from the heart?
My mouth turned dry, and I knew I would be able to get out only a few words clearly. “Daniel,” I said, “If I could have picked, I would have picked you.” That's all I could say. He hugged me. For a moment, the world 51 , and there were just Daniel and me. He was saying something, but tears misted my eyes, and I couldn't understand what he was saying. All I was 52 of was the stubble（短须）on his chin as his face pressed 53 mine. What I had said to Daniel was 54 . It was nothing. And yet, it was 55 .
