Vitamin E supplements(补充品)，which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday.?

In fact, people taking high doses(剂量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters.?

Miller and colleagues re?analyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together，”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.”?

Miller, whose findings are also being published online by the Annals of Internal Medicine, said two?thirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E.?

A.they can lose weight easily?

As the forceful king of Macedonia(马其顿), Alexander the Great overthrew the Persian Empire, becoming a hero that would survive centuries after his death.
Born in 356 B.C., Alexander III was the son of Philip II and Olympias. Alexander’s parents wanted him to receive the finest education, and arranged for him to study under Aristotle, regarded as one of the greatest scholars.
Alexander’s father was a strong leader. Philip II built an impressive army and established the Macedonian kingdom; he was even planning to attack Persia shortly before his death.
In 336, Philip was murdered by one of his guards. Although it was obvious that the guard had a personal hatred, there are clues that other people were related to it.
After Alexander was cleared as a suspect, he succeeded his father without opposition, and killed those said to be responsible for his father’s murder, as well as all rivals. He was then just 20 years old. He then prepared to attack Persia.
In the spring of 334, Alexander led the army made up of nearly 50,000 soldiers into Asia, which is called “the most powerful military expedition ever to leave Greece”, He soundly defeated the Persian army at the Granicus River, sending a strong message to Darius III, leader of the Persian Empire.
In 333, Alexander faced Darius at Issus, a mountain pass. The Macedonian army was greatly outnumbered but able to work the narrow mountain passageway to their advantage. Darius managed to escape. Continuing down the Mediterranean Coast, Alexander took every city in his path.
In 332 Alexander declared Egypt to be part of the Greek Empire and was crowned Pharaoh(法老).
When Alexander left Egypt in 331, he defeated the Persians again and was crowned leader of Asia.
In 323, however, Alexander developed a fever on the way back home and died 10 days later at Babylon. He was just 33 years old.
【小题1】What can we know about Philip’s death?

A．e, d, b, c, a	B．d, e, a, c, b
