Alexander Glassman presented the findings recently during the yearly meeting of the American Psychiatric Association. Doctor Glassman is the director of an antismoking center at Columbia University in New York City. His study examined 100 smokers who have a history of depression. People with depression suffer periods of extreme sadness.
The researchers studied people who have succeeded and those who have failed in their efforts to stop smoking. The study found that people who did stop smoking were two times as likely to suffer from depression again within six months as those who continued to smoke.
Doctor Glassman says smokers who are depressed use tobacco to make themselves feel better. But, he says people with depression seem to have a much harder time stopping than non-depressed smokers.
So, drugs to fight depression are now also being used to help people stop smoking. Doctors say the most effective one is called Buproprion.
Buproprion mainly affects the brain chemical dopamine(多巴胺). nicotine(尼古丁) is a substance in tobacco that also affects dopamine. Buproprion helps people stop smoking because it eases the body's desire for nicotine. Doctor Glassman says the drug does not make people stop smoking. But it makes it easier for those who want to stop.
When people with depression tried to stop smoking they are ______.
A．as likely to fail as non-depressed smokers
B．more likely to fail than non-depressed smokers
C．more likely to succeed than non-depressed smokers
D．most likely to succeed among the smokers
A．encourage themselves to smoke more
B．make themselves worse
C．comfort themselves
D．damage their lungs
A．the use of man-made materials has had harmful effects on the modern civilization
B．pollution has become a more and more serious problem that is threatening the survival of humanity
C．our technological achievements have grown very rapidly in the last twenty years
D．we should not make increasing industrialization our chief aim
A．Right
B．Wrong
C．Not mentioned
A quick review of ancient history since men began keeping records of their achievements would show that all the great empire (帝国) builders were also road builders. They knew well that good roads were necessary for keeping the extended empire together.
The first of the great empire road builders were the Persians (波斯人). Between 500 and 400 B. C. all the parts of the Persian Empire were connected by roads with the capital city. The main, or "royal", road began near what is now Turkey(土耳其), and ended in Susa. The road had well-built inns where travelers could rest and eat, and tax-houses like those on a modern highway.
The people of Greece, unlike the Persians, believed that their city-states could remain independent only if the roads between them were not too good. Besides, the landscape (风景) full of mountains in Greece made road building an extremely difficult job. As a result, the Greeks turned to the sea, and instead of highways, developed sea routes that reached distant lands.
By far the greatest of the ancient road builders were the Romans. The Romans, like the Persians before them, recognized the importance of land routes to keep their empire together. At the height of its power, the Roman Empire covered about 2,000,000 square miles. It extended from Spain in the west to the banks of the Caspian Sea(里海) in the east. And from England in the northwest, the empire stretched south to include the coastal lands of North Africa. By about 120 A.D. the Romans had built an extraordinary network of about 50,000 miles of roads. The roads were originally built for military traffic moving from one part of the empire to another, but during periods of peace these same roads were busy with traders and travelers.
You can still travel over Roman roads in many parts of Europe today. The Roman engineers knew how to build things that would last and last.
The Persians started to build roads about ______.
A．500 years ago
B．2000 years ago
C．1600 years ago
D．2500 years ago
