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,攝入), 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 (增強) 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.

1.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 can lower cancer risk                   D.it is not taken enough every day

2.Which of the following can not help people get more Vitamin D?

A.Have some sunshine                     B.Have more meat

C.Have more fortified cheese                D.Have a vitamin supplement

3.Which of the following food can lower people‘s chance of getting cancer?

A.Milk             B.Fortified orange juice                    C.Fortified yogurt  D.All of the above

Looking back on China’s road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years.

After China’s first satellite into the Earth’s orbit in 1970 came four flights of unmanned Shenzhou missions(飛行) from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China’s second human spaceflight, was launched, with a crew of two astronauts. What’s more, the landmark(里程碑)spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration.

Meanwhile, China’s moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world’s first man-made satellite, China’s first circumlunar(繞月的)satellite Chang’e 1 took off on Oct.24, 2007, which became the third landmark in China’s space achievements after the above-mentioned manned flights. Chang’e 1 was expected to fulfill four scientific goals, one of which was to expore mineral elements on the moon, especially those not existent on Earth. It’s said that the lunar regolith(月壤) is abundant in helium-3, a clean fuel that may support the Earth’s energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the launching of Chang’e 2, China’s 2nd unmanned lunar probe(勘探), marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang’e 3 and Chang’e 4, as a preparation for a soft lunar landing in the future.

With great expectations, people all over the world are looking forward to China’s greater space achievements.

1. According to the text, which of the following is TRUE?

A. China sent its first satellite into the Moon’s orbit in 1970.

B. China is the third country in Asia to make human spaceflight.

D. The launching of Chang’e 1 became the third landmark in China’s space achievements. 

2. Paragraph 2 mainly deals with information about China’s         .

A. landmark spacewalk                 B. manned Shenzhou missions

C. first circumlunar satellite              D. unmanned Shenzhou missions

3.We can infer from the text that         .

A. China’s road to outer space has not been very smooth for a long time

B. the lunar regolith is believed to be rich in a clean fuel called helium-3

C. China’s lunar exploration project was started in 2004 and completed in 2007

D. China’s scientists are researching into techniques for soft lunar landing

4.What can be the best title for the text?

A. Ancient Chinese’s Dream          B. China’s Major Space Achievements

C. China’s Moon Exploration         D. The World’s Great Expectations 

5.The auther’s attitude towards China’s space exploration is _________.

A.negative         B.positive         C.critical         D.indifferent
