　　Two year s ago, Wendy Ha snip, 47，experienced a brain injury that left her speechle s s for two week s．When she finally recovered, she found her self talking with what seemed to be a French accent．“I phoned a friend the other day, and she spent the fir st ten minute s laughing, ” Ha snip said at the time, “while I have nothing again st the French．”

　　Ha snip suffered from foreign accent syndrome(外国口音综合症), a rare condition in which people find them selve s speaking their own language like someone from a foreign country．The condition u sually occur s in people who have experienced a head injury or a stroke-a sudden lo s s of con sciou sne s s, sen sation, or movement cau sed by a blocked or broken blood ve s selin the brain．

　　The condition wa s fir st identified during the Second World War in a Norwegian woman who se head wa s injured during an attack by the German military．The woman recovered but wa s left with a German-sounding accent, to the horror of fellow villager s who avoided her after that．

　　Re searcher s have di scovered that the combined effect of the damage to several part s of the brain make s victim s lengthen certain syllable, mi spronounce sound s, and change the normal pitch(音高)of their voice．Tho se change s in speech add up to what sound s like a foreign accent．

　　Another re searcher, a phonetician, say s victim s of the syndrome don't acquire a true foreign accent．Their strangely changed speech only re semble s the foreign accent with which it ha s a few sound s in common．

Plastic is one of the most important technological discoveries of the 20th century. However, it may soon be replaced. The new development- liquid wood- can replace plastics in all branches of modern-day industries.
Plastic as a material enjoys the biggest demand in the modern world, but it does have a number of drawbacks. First and foremost, plastic isn’t recyclable. Secondly, it contains toxins (毒物) helping develop cancerous diseases. Finally, it’s made of oil and oil reserves aren’t endless.
The liquid wood technology is likely to replace plastic and providing mankind with new materials for many years ahead. Norbert Eisenfreich, a senior researcher at the Faunhofer Institute for Chemical Technology in Germany (ICT), said that arboform, the new material, is made of lignin(木素质）, which can be obtained from soft tissues of wood. Once mixed with several other matenals, it turns into solid and non-toxic alternative for plastics.
ICT team leader Emilia Regina Inone-Kauffmann said the wood-working industry separates wood into three basic components, including lignin. Lignin isn’t used for the production of paper. Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded (铸型）.
When solid, arboform looks like plastic and possesses tho qualitie of polished wood. It can be used for the production of any items. Arboform is already used for the production of car parts which require extra strength. In addition, liquid wood can be recycled repeatedly. The material preserved all of its qualities even if it’s reprocessed ten times.
However, the new invention doesn’t enjoy an extensive use due to the high content of sulfur(硫) in it. German researchers are sure to reduce the amount of sulfur by 90% very soon to make arboform usable for home needs.

Seven Health Facts about Coffee

Whe.n you’re consideringyour.morning coffee, here are some healthfacts to keep in mind:

1, Coffee Reduces Your Risk of Diabetes（糖尿病）

In a 2005 review of nine studies, researchers found that for those that drank four to six cups of coffee per day, versus only. Two or fewer, their risk for Type 2 diabetes decreased by almost 30 percent. The number decreased:d by 35 percent when people drank more than six cups per da3day.And if you’re picturing yourself f running around the’office with your eyes bugging out of your head, no worries because caffeinated and decaffeinated coffees provided much the same results.

2. Coffee Fights Free Radicals（自由基）

We often forget that coffee is actually a plant and like all plant foods, the coffee bean contains more than 1,000 naturally occurring substances called phytochemicals, which may help prevent disease. Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.

3. Coffee Improves Memory and Cognition

Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information. Coffee can also improve cognitive function as we age. One study found that combining coffee with a sweet treat had an even bigger impact.

4. Coffee Can Increase Osteoporosis（骨质疏松）

It s true that coffee can cause the body to excrete calcium in urine. We don’t want the.body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel,about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.

5. Coffee Causes Wrinkles

Even tho,ugh coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration(脱水) which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better,add one tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.

6, Coffee Can Actually Cause Weight Gain

The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it,’according to iVillage. Coffee is also socially connected to food. For example,we pair coffee with dessert or that morning powdered doughnut. Additionally, when we crash fiom our caffeine high that’s when we reach for all sorts of fatty snacks’ to keep us going.

7. Conventional Coffee Is Laden with Pesticides（杀虫剂）

The coffee plant is one of the most heavily sprayed crops. Lt’s coated with chemicals,pesticides, and herbicides, nothing you’d want to be swallowing. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that.leech into our ground water and can make us sick down the road.

If you switch to decaffeinated coffee, make sure the caffeine（咖啡因） is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular.

41. If you want to decrease the risk of diabetes by 35070, you need to take at least cups of coffee every day.

A. seven B. six C. five D. four

42.lf you are a heavy drinker of coffee, a far better way to avoid wrinkling of your skin is to drink water .

A.less than usual B. regularly C. with sugar D. with chia seeds

43. Which of the following statements is wrong?

A. Adding two spoons of milk to a cup of coffee can prevent calcium losses.

B. Decaffeinated coffee has different effects from caffeinated coffee as to diabetes.

C. Many phytochemicals protect the cells from damage from fiee radicals.

D. The organic variety of coffee p/ant is free from assorted chemicals.
