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.

    How much weight a baby gains during its first month could determine its IQ, as a new research suggests. The study found that children who gain more weight, and whose heads grow quickly during the first month of life, tend to have a higher IQ when they start school.

    Researchers at the University of Adelaide, in Australia^ studied 13,800 children who were born at full-term. They found that those who put on 40% of their birth weight in the first four weeks had an IQ 1.5 points higher than those who only put on 15% of their birth weight. Those who experienced the biggest growth in head circumference (头围) also had the highest IQs by the age of six.

“Head circumference is an indicator of brain volume, so a greater increase in head circumference in a newly-born baby suggests more rapid brain growth,” says the led author of the study, Dr. Lisa Smithers.

    She added, “Overall, newly-born children who grew faster in the first four weeks had higher IQ scores later in life. Those children who gained the most weight scored especially high on verbal (言语) IQ at age 6. This may be because the neural (神经的) structures for verbal IQ develop earlier in life, which means the rapid weight gain during the first month could be having a direct cognitive benefit for the children.”

    Previous studies have shown the association between early postnatal (产后的) diet and IQ, but this is the first study of its kind to focus on the IQ benefits of rapid weight gain in the first month of life. Dr. Smithers says the study further highlights the need for successful feeding of newly-born babies. “We know that many mothers have difficulty establishing breastfeeding in the first week of their babies' life,” Dr. Smithers said.

    “The findings of our study suggest that if babies are having feeding problems, there needs to be early intervention (干预) in the management of that feeding.”

    A thief entered the bedroom of the 30th President of the United States, who met him and helped him escape punishment.

    The event happened in the early rooming hours in one of the first days when Calvin Coolidge came into power, late in August, 1923. He and his family were living in the same third­floor suite (套房) at the Willard Hotel in Washington that they had occupied several years before. The former President's wife was still living in the White House.

    Coolidge awoke to see a stranger go through his clothes, remove a wallet and a watch chain.

    Coolidge spoke, “I wish you wouldn't take that.”

    The thief, gaining his voice, said, “Why？”

    “I don't mean the watch and chain, only the charm (表坠). Take it near the window and read what is impressed on its back.” the President said.

    The thief read, “Presented to Calvin Coolidge.”

    “Are you President Coolidge？” he asked.

    The President answered, “Yes, and the House of Representatives (众议院) gave me that watch charm. I'm fond of it. It would do you no good. You want money. Let's talk this over.”

    Holding up the wallet, the young man said in a low voice, “I'll take this and leave everything else.”

    Coolidge, knowing there was $80 in it, persuaded the young man to sit down and talk. He told the President he and his college roommate had overspent during their holiday and did not have enough money to pay their hotel bill.

    Coolidge decided to offer the man and his roommate two rail tickets back to the college. Then he counted out $32 and said it was a loan (借款)．

    He then told the young man, “There is a guard in the corridor.” The young man nodded and left through the same window as he had entered.

    How many calories are there in every meal you eat? That seems like a difficult question to answer. But students at Aitkin High School in the United States can easily answer it now. They put what they eat into an online calorie counter（计算器）. It quickly measures the amount of calories in their meals.

    In fact, this is part of the school's health class. It includes heart health, nutrition and fitness. Students can learn basic knowledge about fats, proteins, calories and sugar.

    Students learn how to balance calories in and out. They will know what happens when the balance isn't there. “The online calorie counter has turned out to be a cool tool to help you make healthy choices. Making one healthy eating decision can really make a difference.” Adam Carlson, the teacher in charge, told local newspaper Aitkin Independent Age.

    They also discus good ways to burn calories in the gym. According to Carlson, the gym is a great place to burn calories and get stronger. But it doesn't work for everyone. So they try to find different workout tips. “I'm trying hard to teach the students that working out can be fun, challenging, and doesn't need to take hours out of the day,” she said.

    The class has indeed changed students. “I am now watching what I am eating and pay attention to the food labels,” said seventh-grader Karena Burgstaler. Another student James Erickson began to control his sugar input because it almost went over his daily calorie intake goal.

    Last year, around Labor Day, I read a “Happy Ad” in our local newspaper. There was a lady in a local nursing home for the aged, who was celebrating her 90th birthday and her family wanted everyone to know about it. It said that if you wanted to drop her a line, here was her address. So I did. I found a birthday card and dropped her a short note, wishing her a happy birthday.

    A week or so later, someone knocked at my front door. I opened the door and found a middle-aged man standing on my doorstep. He introduced himself as the son of this woman to whom I had sent the card. He explained that he just wanted to drop by in person and thank me for sending such a nice card to his mom. Apparently, like many older folks, she did not receive much mail and was quite excited to receive mine. I just didn't know what to say. I told him it was my pleasure and that I hoped his mom had enjoyed her birthday.

    That year, I did not send out any Christmas cards, except to this lovely old lady in the nursing home. I just told her that I was thinking about her and hoped that she had a nice holiday. I sent her a holiday card and also a couple of notes in between. I just thought she might like to have someone write to her, to get some mails.

    She passed away a couple of months ago. I never met this lady, but I did keep her and her family in my thoughts. I dropped them a line of sympathy. I hope that my few little notes were enough to brighten a couple of her days here on earth.

    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, "He's the brains in the family." And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase "brain trust" became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues（问题）facing the U.S. These professors were called his "brain trust".

    These ways we use the word "brain" all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word "drain". As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.
