Seven years without a cold?

More and more people saying they just don't get colds anymore. They are using a new device made of pure copper, which scientists say kills cold and viruses. Doug Cornell invented the device in 2012. “I haven't had a single cold since then,” People were skeptical but EPA and university studies demonstrate repeatedly that viruses and bacteria die almost instantly when touched by copper. That’s why ancient Greeks and Egyptians used copper to purify water and heal wounds. Scientists say the high conductance (传导性) of copper disrupts electrical balance in a microbe (微生物) cell and destroys the cell in seconds.

So some hospitals tried copper touch surfaces like taps and door handles. This cut the spread of MRSA and other illnesses by over half, and saved lives. Colds start after cold viruses get in your nose, so the vast body of research gave Cornell an idea. When he next felt a cold about to start, he fashioned a smooth sheet copper and rubbed it gently in his nose for 60 seconds. “It worked!” he exclaimed, “The cold never got going.”

He asked relatives and friends to try it. They said it worked too so he patented CopperZap and put it on the market. Now tens of thousands of people have tried it. Nearly 100% of feedback says the copper stops colds if used within 3 hours after the first sign. Pat McAllister, age 70, received one for Christians and called it “one of the best presents ever.” “This little jewel really works,” People have used it on cold sores and say it can completely prevent outbreaks. It kills germs picked up on fingers and hands to protect you and your family. Copper even kills deadly germs that have become resistant to antibiotics.

1.D 2.C 3.C 4.B 【解析】 这是一篇说明文。文章介绍了一款名为CopperZap的产品可以杀死感冒和病毒,从而让人不得感冒。文章说明了这个产品的工作原理、发明过程以及价格等情况。 1.细节理解题。根据第一段最后一句Scientists says the high conductance of copper disrupts the electrical balance in a microbe cell and destroyed the cell in seconds.可知,科学家表示,铜的高导电性破坏了微生物细胞的电平衡,并在几秒钟内破坏了细胞。由此可知,设备中的铜会破坏一个细胞中的电平衡,从而破坏这个细胞。故选D。 2.词义猜测题。根据上文When he next felt a cold about to start, he fashioned a smooth sheet copper and rubbed it gently in his nose for 60 seconds.可知,当他再次感到快要感冒时,他做了一个光滑的铜板,在鼻子里轻轻地擦了60秒。以及后文“The cold never got going.”(感冒没再继续了)可知,光滑的铜板在人身上起作用了。由此可知,“It”一词在第2段中指的是光滑的铜板。故选C。 3.细节理解题。根据倒数第二段中It is $69.95. Get $10 off each CopperZap with code USA3.可知。它的价格是69.95美元。每个带有代码USA3的CopperZap可以获得10美元的优惠。由此可知,如果您想购买代码为USA3的CopperZap,您将支付69.96-10=59.95美元。故选C。 4.推理判断题。根据最后一句话Buy once, use forever.可知,一次购买,永远使用。由此可推知,这篇文章的目的是说服人们购买产品。故选B。

    It was late, about 10:15 p.m, when Janice Esposito arrived at the New York train station and began the 20-minute drive home. She had traveled the route so many times that she almost drove on autopilot (自动驾驶):a left onto Station Road, then a left on Montauk Highway, and then-bang! Out of nowhere, a car T-boned Janice’s car, pushing her backward onto the railroad tracks.

As it happened, Pole DiPinto was gelling ready for bed. He'd just closed his book when he heard the loud crash not far outside his bedroom window. A volunteer firefighter and retired teacher, 64, never stopped to think, He grabbed a flashlight and still in his pajamas (睡衣), ran out the door. “Any firefighter would have? done what I did,” he said, “We're always on duly.”

The first car he came upon was the one that had hit Janice. Once DiPinto concluded the driver was OK, he looked around and spotted Janice's car lay across the railroad tracks. And then he heard a terrible sound: the bells signaling an on-coming train.

DiPinto rushed to Janice's cur and banged on the driver's side window. She just looked at him, her eyes unfocused. “I don't know where I am,” she said. She seemed unhurt. “Honey, you're on the railroad tracks,” DiPinto shouted, “We have to get you off right now!” He pulled hard on the door handle, but it didn't work. The heavy train, traveling at 65 miles per hour, was heading toward them. DiPinto ran to the passenger side and threw open the door. “Please, God, don't let her be trapped”, he thought. He pushed aside the airbags, grabbed Janice's arms, and pulled her toward him across the passenger seat until he could help her out and walk her to safety. Within six seconds, he estimated, the train crashed into the car.

“It was like a Hollywood movie,” DiPinto told reporters the next day. But this one had a difference. That night, the hero arrived in pajamas, not in a fire truck.
