Why do some people flush when they drink alcohol? This effect is a common reaction to alcohol among East Asians. It affects about 36 percent of Japanese, Chinese and Koreans.

For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation, increased heart rate, shortness of breath and headaches.

The cause is a genetic difference that they are born with called an ALDH2 deficiency (缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus (食道) from drinking alcohol.

The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.

Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world’s population.

Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.

2.The second paragraph is mainly about _________.

A．the cause of the effects of alcohol

A．about 36 percent of Japanese, Chinese and Koreans are heavy drinkers

B．the ALDH2 deficiency may be passed on from generation to generation

C．unpleasant effects occur only when people with this deficiency drink a lot

D．only some East Asians have the ALDH2 deficiency

There’s no doubt that man is the smartest. But do you know what other animals are smart, too?

Dolphins

Dolphins are very smart. Most of the “tricks” they’re taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins’ mothers always provide their young children with guidance and possibly, love.

Great apes

The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans’ that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships.

Elephants

Everyone has heard the phrase “an elephant never forgets”. Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad.
