Ordman, Professor of Biochemistry at Beloit College, Wisconsin, is to take it twice a day--one 500 milligram does every 12 hours.
"If vitamin C really does work as an antioxidant, then taking a supplement once a day might be like wearing a condom half the time." Professor Ordman said. "Nobody has ever thought to look at how much you have to take to keep the level elevated."
In a study published in the current issue of the gerontology journal Age, Professor Ordman gave varying doses of vitamin C at different times to students and measured the amount excreted in their urine. He found a 500 mg dose was needed every 12 hours "to enrich the blood just enough to ensure there is a little bit leaking out all the time." This compares with the US-recommended adult daily allowance of 60 mgs.
Recommended levels of vitamin C, and other vitamins, have been raised following recognition of their role in mopping up "free radicals" in the blood linked with a range of diseases. However, the British figure of 40 mgs daily for vitamin C is still below the U.S. figure and likely to be raised again.
Research on megadoses of vitamin C of 10 and 20 times this level have shown it to have some protective effect against the common cold taken at the first sign. But there is no evidence of a beneficial effect against other diseases of doses vastly higher than the recommended daily amounts.
LINUS PAULING, the Nobel Laureate, whose book on vitamin C and the common cold in 1970 popularised the idea of taking fistfuls of supplements, is said to have swallowed 10,000 mgs a day. It is because it is water-soluble and quickly excreted that vitamin C is safe in such quantities; it does not build up in the tissues.
Professor Ordman's twice-daily regime may help keep blood levels of the vitamin high. But dosing on the scale followed by Pauling, who died last August aged 93, will seriously damage your bank balance--at $ 2,500 a year.
7. What do you know about Professor Ordman's view towards vitamin C from the passage?
8. Why was the Nobel Prize winner Linus Pauling mentioned in the passage?
9. Explain in your town words the sentence from paragraph 2 "Most of it, however, goes straight down the pan".
10. What is concluded about effects of megadoses of vitamin C in the passage?

SECTION 6: TRANSLATION TEST (30 minutes)
Directions: Translate the following passage into English and write your version in the corresponding space in your ANSWER BOOKLET.
1995年10月，黃浦江上又一座大橋凌空飛架，將浦南與奉賢連接起來(lái)，成為繼徐浦、南浦、楊浦三座大橋之后建成通車的第四座大橋——奉浦大橋。
奉浦大橋是首座由地方籌資興建的黃浦江大橋，奉賢縣與市區(qū)有關(guān)部門(mén)和企業(yè)共同集資4.46億元，僅用1年零7個(gè)月的時(shí)間即勝利建成。大橋的建成解決了長(zhǎng)期困擾奉賢與浦南地區(qū)的過(guò)江問(wèn)題，同時(shí)還改善了該地區(qū)的投資環(huán)境，為杭州灣北岸的開(kāi)發(fā)、建設(shè)打下了良好的基礎(chǔ)。
金秋10月的黃浦江畔，徐浦、南浦、楊浦、奉浦四座大橋沐浴著金秋陽(yáng)光，各顯神姿，交相輝映，為上海這座充滿生機(jī)與魅力的國(guó)際大都市增添了更加奪目的風(fēng)采。不久的將來(lái)，上海還將建造更多的過(guò)江設(shè)施，把浦江兩岸更緊密地連結(jié)在一起。
