Vitamin E supplements(補(bǔ)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(劑量)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.?

People take vitamin E supplements, hoping that________.?

A.they can lose weight easily?

B.they may live a longer and healthier life?

C.they can get more and more beautiful?

As the forceful king of Macedonia(馬其頓), 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.
【小題1】What can we know about Philip’s death?

A．He was killed by someone intending to take power from him.
B．Alexander sent someone who hated Philip to kill him.
C．His death was related to his plan of fighting Persia.
D．The murder might be organized by a group of people.
【小題2】The Macedonian army could defeat the Persians at Issus mainly because _________.
A．Darius didn’t command his army in the battlefield
B．Macedonian soldiers were more than the Persian soldiers
C．Macedonian soldiers could fight better at the mountain pass
D．Macedonia was more powerful than the Persian Empire
【小題3】In which order did Alexander do the following things?
a．Totally overthrew the Persian Empire.
b．Defeated the Persian army at Issus.
c．Was crowned Pharaoh of Egypt.
d．Defeated the Persian army at the Granicus River.
e．Became the leader of Macedonia.
A．e, d, b, c, aB．d, e, a, c, b
C．e, b, d, c, aD．d, a, c, e, b

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
Possessing a car gives one a greater degree of freedom. With the building of good fast motorways, long distances can be covered rapidly and pleasantly.    【小題1】   You will no longer be forced to rely on public transport and work locally. You can choose from a greater variety of jobs and probably changes your work more frequently as you are not limited to a small area.
Although you can afford to buy it now, you have to consider the future.    【小題2】  However large the first sum you have to pay, you have to spend more in running the machine—the various taxes, the fuel, and of course the repairs. The last is especially endless. Any single repair may cost you thousands.
  【小題3】   As more and more cars are produced and used, an even larger amount of poisonous gas is being sent out. Some of the contents of this gas, such as lead, can cause actual harm to the health of people. Many of the minor illness of modern industrial society, headaches, tiredness, and stomachaches may just arise from the gas.
   【小題4】    It has been said that when a man is sitting behind the wheel, his car becomes the display of his personality. People who are normally quiet and pleasant may become unrecognizable when they are behind the wheel. They are ill-mannered and aggressive and selfish. All their hidden character seems to be brought to the surface by act of driving.
Traveling by car actually brings more inconvenience. Driving a car may be more comfortable than taking a crowded bus. But any advantage of driving a car is often gone in traffic jams, endless queues of cars through all the main streets.   【小題5】   

A．Driving a car often brings out a man’s worst qualities.
B．Driving a car may cause many traffic accidents.
C．If you have a car, you can move around freely.
D．Considering this, I don’t support the use of more cars.
E. A car may bring you heavy financial burden.
F. More cars can produce serious air pollution.
G. Knowing you are able to drive makes you more confident.
