Do you still remember the haze（雾霾）in the winter? So many people got terribly ill during or after the haze. {#blank#}1{#/blank#}Here is advice for you to protect yourself in hazy weather.

    Spend less time outdoors.This is the most effective way for self-protection in such bad weather.With PM2.5 increasing 103mg per cubic meter,residents will risk a 2.29% increase of death,which experts found out in 2012.If you have to get out,avoid riding bicycles.{#blank#}2{#/blank#}

    Close your windows.Experts advice residents to avoid opening windows at home.If you have to ,avoid the time when smog is at its densest（浓的）.{#blank#}3{#/blank#}Besides,you can keep plants with broad leaves at home to absorb dust,and use air purifiers（清洁器）.

    Smoke less.{#blank#}4{#/blank#}In hazy weather,smoking would be even more harmful.Smokers are advised to keep their distance from cigarettes before the weather gets better.

    {#blank#}5{#/blank#}For example ,wear special masks outside to avoid breathing in PM2.5.Then take off your coat after getting indoors and keep it away from your other clean clothes,Don't forget to wash your face,rinse（漱）your mouth,and clean your nasal cavity（鼻腔）to clean the particulate matters（颗粒物）that fall on you.Last but not least,keep off stimulating（刺激性）foods.

A.Wear masks.

B.Pay attention to other daily things.

C.Also avoid rush hours,when pollutants will be denser.

D.That's because haze does harm to the health of people.

E.Cigarettes could cause more particulate matters,which are included in PM2.5 .

F.Take more fruits and vegetables instead,which are good for lung,spleen（脾）and kidney（肾）.

G.For residents who use air-conditioner,make sure your apartment has enough oxygen indoors.

    Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.

    People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf of the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.

    A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them —perhaps by pulling off its leaves or by pulling it out of its pot—then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signaling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living thing such as insects (昆虫).

    Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.

    Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed on his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.

    Back in the 1860s, a British scientist named Henry Walter Bates noticed something interesting in the animal world: a kind of butterfly, Common Mormon, can change the pattern on its wings so that it looks like another butterfly species, the Common Rose, which is poisonous for birds to eat.

    Bates argued that animals develop this ability to protect themselves from being eaten. This theory had been widely accepted by scientists. But one question remains: how do these animals manage to do that?

    After more than 150 years, scientists are finally able to answer that question-it is all down to a gene(基因) called “doublesex", according to a study published on March 6 in the journal Nature.

    In fact, scientists have long known that genes are responsible for this useful ability. But until the new study, scientists hadn't been able to find out which genes in particular were responsible.

    Scientists at the University of Chicago compared the genetic structures of the Common Mormons that changed their wing patterns with those of ones that did not. And all the results pointed to a single gene, “doublesex”.

    This was much to the scientists' surprise. They used to expect that something as complex as this would be controlled by many different genes. For example, one gene would control the color of the upper part of the wing, one would do so for the lower part.

    However, the “doublesex” gene doesn't quite do everything by itself. Instead, it acts like a switch-it “tells” other genes to change the wing patterns. Isn't that clever?

    Scientists believe that this special ability of the “doublesex” gene on Common Mormon was developed throughout the long history of evolution. “The harmless species gains an advantage by resembling something predators(捕食者) avoid,” Sean Carroll, a scientist told Nature. “it was obvious evidence for natural selection.”

    Shape

    According to their website, Shape is a magazine for American women with active lifestyles. This women's health magazine covers everything from diet and exercise to psychology. What is great about Shape is that it knows that it must cover a lot more than Fitness to give women all the information they need to stay healthy. Besides all the great features included in their print magazine, they also have an easily accessible website that anyone can use.

    Women's Day

    Women's Day is not only specifically a women's health magazine, but also includes a little of what Shape has, along with more information on other parts of life: family, money, travel and style. Many of the articles in Women's Day deal with specific diseases that are common to women, such as heart disease, breast cancer and others.

    Women's Health

    From tips to recent health news to articles about world affairs, Women's Health has everything that you expect in a women's health magazine. Another great feature is that Women's Health has a great website full of information, as well as articles from past magazines that you can check out. This is a great resource, since it lets you get to see articles well at the office.

    Fitness

    This magazine covers important topics such as physical fitness, health & beauty, and mental health. It offers something new in each issue, and it's always easy to understand.

    The workouts are clearly presented with good photos to illustrate (说明) every movement, and almost all can be done without making a trip to the gym.

    In university I had a part-time job at a shop that sold doughnuts and coffee. Situated on a block where several buses stopped, it served the people who had a few minutes to wait for their bus.

    Every afternoon around four o'clock, a group of schoolchildren would burst into the shop, and business would come to a stop. Adults would glance in, see the crowd and pass on. But I didn't mind if the children waited for their bus inside. Sometimes I would hand out a bus fare when a ticket went missing — always repaid the next day. On snowy days I would give away some doughnuts. I would lock the door at closing time, and we waited in the warm shop until their bus finally arrived.

    I enjoyed my young friends, but it never occurred to me that I played an important role in their lives — until one afternoon when a man came and asked if I was the girl working on weekdays around four o'clock. He identified himself as the father of two of my favorites.

    "I want you to know I appreciate what you do for my children. I worry about them taking two buses to get home. It means a lot that they can wait here and you keep an eye on them. When they are with the doughnut lady, I know they are safe." I told him it wasn't a big deal, and that I enjoyed the kids.

    So I was the Doughnut Lady. I not only received a title, but became a landmark.

    Now I think about all the people who keep an eye on my own children. They become, well, Doughnut Ladies. Like the men at the skating rink (滑冰场) who let my boys ring home; Or the bus driver who drove my daughter to her stop at the end of the route at night but wouldn't leave until I arrived to pick her up; Or that nice police officer who took pity on my boys walking home in the rain when I was at work — even though the phone rang all the next day with calls from curious neighbors. "Was that a police car I saw at your house last night?"

    That wasn't a police car. That was a Doughnut Lady.

    Edward Latter, five, thought his dog Morse was gone for ever after cruel thieves took him away when the dog escaped from his home.

    The 10-month-old dog had been missing since December and the broken-hearted boy even wrote a heartbreaking letter to Santa and posted it to Lapland asking for his pal back for Christmas.

    A ￡10,000 reward was offered by millionaire Simon Cowell after he read about the horrific theft. Cowell said: "It's heartbreaking to see a little boy's Christmas ruined. Dogs are so important to many of us. We just hope it helps lead to the safe return of Morse."

    His parents, Amanda Hopkins and Richard Latter, had given up hope of ever seeing their pet again, until they got a call on Friday night. A couple 20 miles away from their home in Marden, Kent, had found a muddy dog walking through their street and thought it could be missing Morse. They brought the Morse in, washed him, and then called Mr Latter who was unsure until he was sent a photo, and then drove the family to the village of Meopham.

    The theatre carpenter, 40, said: "Amanda and I were still quite sceptical, but Edward saw him and recognised him straight away. He was absolutely over the moon. He said: 'I can't believe it, I have my best friend back. It's too late for Christmas but this is the best present ever.' We were still unsure if it was him though—as he wasn't responding to his name or coming to us."

    "We spent about an hour and half over there and we still were not sure, so we took him home to get his chip scanned. It was only when we took him to the vets on Saturday morning and got his chip scanned that we found out for sure. We instantly broke down in tears. We were just hugging each other, hugging Edward and hugging the dog." Added Richard.

    The family who found missing Morse said they hadn't yet heard from Simon Cowell about the ￡10,000 reward hut were happy to get him home.
