Shlander is a man from space. He thinks the people and things on the earth are very strange. He is now writing a letter to his friend at home. Here is part of his letter. Read it and answer the questions.

    Now I am in a strange world. It is very nice. There are many new things here. There are many earth monsters (怪物) here, too. The earth monsters look very funny. They have just one head, two arms and two legs. They have thin black strings(细绳) on their heads. Some earth monsters have brown or yellow strings. The earth monsters have a hole in their faces. Every day, they put nice things and balls from the trees into the hole. They put water into the hole, too. The earth monsters do not walk very fast. They move from place to place in tin boxes.

    At night, the earth monsters like to look at a square window box. This box has very small earth monsters in it.

    In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.

    But why , they pleaded. “Because I don't have time to take care of a dog.” But we'll do it. ” Really? You're going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don't believe you .” We will . We promise.

   They didn't . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”

    Quickly, she and I developed something very similar to a Vulcan mind meld (心灵融合) . She'd look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .

    Even so , part of me continued to resent walking duty . Joe and Becky had promised. Not fair , I'd balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I' d loudly remind anyone within earshot upon our return home .

    Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.

    Save one: Misty still needed walking. At the beginning, when friends offered to take her through her paces, I declined because I knew they had their own households to deal with.

    As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.

    When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.

    Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or 'one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.

After Joe died in 2009，Misty slept on his pillow.

    I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m' walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.

    Junxi “Emma” Yang played Carnegie Hall before she got to high school. But her piano skills may have to take a back seat to her programming skill.

    According to World Journal, a US-based Chinese media organization, Emma, a 14-year-old student at the Brearley School in Manhattan, New York started coding when she was 6. Four years later, her beloved grandmother began developing Alzheimer's.

    When Emma's family moved to New York from Hong Kong in 2014, she became passionate about programming. By the time she was 10, her grandmother had already developed the disease.

    Emma got right to work. With her coding skills, she had a smartphone app created before long, designed to help people suffering from Alzheimer's.

    “Now, 'Timeless' has moved to the second stage of design,”says Emma.

    Emma hopes her grandmother can benefit from the artificial intelligence technology built into “Timeless,” the app Emma developed, to overcome her memory loss.

    Emma's newly finished app has gained support from Dr. Melissa Kramps, an Alzheimer's specialist, and from Kairo, a developer specializing in artificial intelligence.

    Timeless uses facial recognition to remind someone with Alzheimer's of vital information about the person whose photo they are looking at on their screen. It also signals whether they have just called somebody.

    The app also allows for the photo-talking, then moves to identify the people on the screen.

    The Timeless project is featured on the website Indiegogo for fundraising. Emma is hoping to raise $50,000 and work alongside professional programmers to have Timeless launched by the end of 2018.

    Many people have hailed Emma for her efforts. Bill Gates voiced his support, commending her on her bid to help bridge the gap between people with Alzheimer's and the ones they love.

    Kyle is my big brother. For eighteen years, I felt that Kyle was my enemy. In fact, I found it ridiculous that people thought older brothers looked out for their sisters, protected them and fought off their sisters，bullies. Huh? My brother was the bully (恃强凌弱者).
    When we were little, his fights with others caused my only black eye, cuts in my lips and even a nosebleed or two. I often wished I were an only child!

    Time flew. We ended up attending colleges two thousand miles apart, yet strangely, that's when we began communicating. Through e-mail, we kept in constant touch. Mostly I complained about serious homesickness, impossible roommates difficult classes, and... dating. I felt I lost myself. At a particularly low time, I cried to Kyle about my injured confidence, my broken heart, and the particular jerk (蠢人) who broke it.

    And that's when the package arrived.

    “What's this?” I thought as I tore into it. The box revealed a sweatshirt. “Phi Delta Theta? Thai's Kyle's frat (兄弟会).” Kyle was the president of the frat house. Why would he send this? I put it aside and dug deeper. A pile of letters. And they were all addressed to me. I opened the one on top.

    “Katrina,” it said, “your brother showed me your picture and I think you're awesome and beautiful.” I rolled my eyes. “Yeah, sure.” I opened another letter. And another. Eighteen in all.

    Each one was from a different guy. They complimented (恭维) me. They invited me on dates. And they tried to convince me to make a trip out to Knox College and meet them.

    I loved it. I didn't care about the motive. And mostly, I loved the idea that my big brother had pulled it off. I picked up the phone.

    “Kyle, the box came and I can't believe what you did.” But Kyle wasn't accepting compliments. “Oh”, he said，“I was just tired of reading your complaints.”

    Big brothers, I decided, really did protect their sisters. And mine fought off the biggest bully I'd ever met. Now I return to my true self，full of confidence.

    Consumer electronics once again topped the list of the most wanted gifts this holiday season.

    "Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology."

    Steve Koenig is with the Consumer Electronics Association. He says the group's latest research also shows that Americans this year are spending more on technology products. "Here in 2012, $252 on average the technology spend for consumers this year."

    From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. "It's kind of hard to make a decision."

    Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple's biggest competitors is the Google Nexus 7. It starts at $199.

    "Its hardware is more powerful than what's in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple's maps.

    But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. "If you just want to read books and surf the Internet, you don't really need to get an iPad Mini, but if you want the largest robust group of apps (应用软件) that's where the iPad and Apple's ecosystem shines the most."

    Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera." You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things."

    Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.

    Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absent-minded actions for two weeks. When he came to analyze their embarrassing lapses(差错)in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. Nor did the lapses appear to be entirely random(随机的).

    One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People program themselves to do certain activities regularly. It was the woman's custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed(颠倒的)in the program," About one in twenty of the incidents the volunteers reported were these "program assembly failures".

    Altogether the volunteers logged 433 unintentional actions that they found themselves doing—an average of twelve each. There appear to be peak periods in the day when we are at our zaniest (荒谬可笑的). These are two hours sometime between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. "Among men the peak seems to be when a changeover in brain 'programs' occurs, as for instance between going to and from work." Women on average reported slightly more lapses—12.5 compared with 10.9 for men—maybe because they were more reliable reporters.

    An astonishing finding of the research is that the absent-minded activity is a risk of doing things in which we are skilled. Normally, you would expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worse—even dangerous.
