It was a hot,humid day, and my brother Walt and I had decided that the only way to surviveit would be to go swimming in a deep swimming hole across Mr. Blickez's pasture(牧场) and through some woods.

    The onlyproblem with our plan was that this pasture was guarded by a huge, meanHereford bull. Mr. Blickez had told us that Elsie was the meanestbull in the township, maybe even the county, and we believed him. But the hotter it got, the more we thoughtthere was something fishy about his claim. For one thing, we remembered Mr. Blickez liked telling tall tales; for another, Elsie seemed like an oddname for a bull.

    Finally, Italked Mom into asking permission for us to walk through the pasture, but thenanother problem surfaced．Mom said she would talk to Mr. Blickez if we would take our cousin Joanie along with us. Joanie was almost two years older than me anda head taller. If her teasingever got around my grade school, it would be all over for me. In fact, I still had a headache from a quarrelwith her that morning.“I'm not goingswimming with that dumb girl cousin.” I told my mom.

  “Either Joaniegoes with, or you stay home alone,” Mom said in her serious tone. I gave in and we set out. On our way across the pasture, Walt yelledsuddenly. Elsie hadapproached him quietly and was licking(舔) his back. Joanie and Idove under the wire fence, but while I was on the ground I looked up and sawthat Elsie wasn't a big mean bull after all. She was going to keep licking my brother's back as long as he stoodstill.

    We had manygood days growing up and visiting our secret swimming hole guarded by theso-called “big mean bull”. And as it turned out, for a girl cousin, Joanie hasn't been too bad. She's been one of my best friends over theyears.

    Spell checks are turning us into a nation of idiots with a third of adults failing to reach the expected spelling ability of an 11-year-old child,a shocking study shows.

    A survey involving 1,000 adults aged between 16 and 77 found that 67 percent would reach Level 4 in Standard Assessment Tests (ASTs),while less than half (44 percent) would achieve Level 5.Fifteen percent of the adults tested even failed to reach Level 3,which is below Level 4—the expected level of children at age 11.Experts blamed the poor showing of the adults on the popularity of tools such as spell check and auto-correct,which both play an important role in modem-day living.

    The study asked adults to complete Key Stage 2 spelling tests designed to judge the performance of children aged 10 and 11,as they reach the end of primary school.But the test spelled trouble for many of the adults tested.The study was charged by King Digital Entertainment,makers of popular mobile games such as Candy Crush.People taking part in the test were asked to spell 35 different words taken from SATs spelling papers from the past three years.In a test which imitated real exam conditions."Phenomenon" and "unnecessary" were among the words spelled wrong by more than half of those participants.Other words which fewer than half were able to spell included rhythmic (42 percent) and jewellery (49 percent).

    Susie Dent.Lexicographer（字典编纂者）and resident word expert on TV show Countdown,believed the results were partly down to the popularity of tools such as spell check and auto-correct.She said,"Tho result is disappointing. It suggests that the ability to spell is losing its importance in our daily lives.Modem tools like spell check and auto-correct encourage us to switch off from learning,leading to satisfaction or,at worst,indifference."

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. "We have technologies to train social robots to do things not for us, but with us," said Breazeal.

    Our family loves the snow and cheers at the first good storm of the season. While others may think of Florida, we dream of a cabin vacation in New York's Allegany State Park.

    One particular trip, I recall, was just a bit more memorable than the rest. What we now refer to as the snow pants incident began accidentally enough. My husband, Bernie, and our 2-year-old daughter, Faith, were building a snow fort while I sledded down a nearby slope.

On the way back up from one trip, I saw a small stone tumbling down the track I had just made. I was puzzled, since all the other rocks were buried under several feet of snow, as I stood and wondered about the stone—it jumped! This was no stone. This was a mouse.

    Now, I love nature, but that doesn't include mice. I loudly protested the invader, and Bernie, coming to my rescue, assured me that this was not a mouse but a mole, as if that mattered. A mouse or a mole I still didn't like it.

    Bernie and I stood for a few minutes watching the creature disappear from the path into the furry white and come back out again. But soon it disappeared and I headed up the hill again.

    Shortly after I left, my husband screamed out, saying that the mole had gone up the leg of his snow pants. You have to understand Bernie can be quite a joker, and I smelled a rat. Not wanting to be a sucker and fall for another one of his jokes, I laughed it off. When he started running for the cabin, though, I stopped laughing and decided maybe this was for real.

    “Don't you dare take that thing into the house!” I yelled. But like a flash, Bernie was already dashing through the cabin's front door, with his snow pants, the mole and all. If it were me, I'd have been down to my long underwear right there in the snow without a second thought.

A few minutes later Bernie appeared. We relished the rest of our winter vacation, drinking lots of hot chocolate, sitting beside the fireplace and admiring nature—from a safe distance.

    Counterfeit(假的) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing.

    People do not get the medicine they need. And in some cases, counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen(对乙酰氨基酚).The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money.

The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The WHO says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan and New Zealand.

    But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit.

    Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms(全息图)on their products as a security device.

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. Then they got a call from one of his daughters: "The house next door is on fire!" He went over and saw three women crying madly on their porch (门廊).

    "The baby's in the second floor!" one of the women cried. Though the fire department had been called, Surrell, then 64, bravely ran inside. "The baby" was Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who has chronic obstructive pulmonary disease(慢性阻塞性肺病), they were life-threatening.

    Taking a deep breath, he moved around in the overwhelming darkness. Because the house had a similar layout to his, he found the stairs and made it to the second floor. Then he heard a soft but clear moan. Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. Finally, he touched something. A shoe, then an ankle. He pulled Tiara toward him, scooped her into his arms and stood. Turning, he fought through the smoke and ran blindly into the blackness…

    Surrell woke up in the hospital a couple of days later and spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire worsened Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. I wouldn't give it a second thought."
