My husband and I had been married nearly twenty-two years when I acquired Stevens-Johnson syndrome,a disorder where my immune system responded to a virus by producing painful blisters（水疱）.Although my long-term evaluation was good,I,who had been so fiercely independent,rapidly became absolutely helpless.

    My husband,Scott,stepped up to the plate,taking care of kids and cooking dinners.He also became my personal caretaker,applying the medicine to all of my blisters because my hands couldn't do the job.Needless to say,I had negative emotions,bouncing from embarrassment to shame caused by total reliance on someone other than myself.

    At one point when I had mentally and physically hit bottoms I remember thinking that Scott must somehow love me more than I could ever love him.With my illness he had become the stronger one,and I the weaker one.And this disturbed me.

    I recovered from my illness,but I couldn't seem to recover from the thought that I loved my husband less than he loved me.This seeming distinction in our love continued to annoy me for the year following my illness.

    Then recently Scott and I went on a long bike ride.He's an experienced cyclist;I'm quite the green hand.At one point with a strong headwind and sharp pain building in my tired legs,I really thought I couldn't go any further. Seeing me struggle,Scott pulled in front of me and yelled over his shoulder,"Stay close behind me."As I fell into the draft of his six-foot-three-inch frame and followed his steps,I discovered that my legs quit burning and I was able to catch my breath.My husband was pulling me along again.At this very moment I woke up to what I now believe: during these and other tough times,love has the opportunity to become stronger when one partner learns to lean on the other.

    I pray my husband will always be strong and healthy.But if he should ever become the struggling one,whether on a bike ride or with an illness,I trust I'll be ready to call out to him: Stay close behind me—my turn to pull you along.

    Mom and Dad are two of the most important people in your life.You probably see at least one of them every day. If your dad worships（崇拜）the Pittsburgh Stealers,you're likely to grow up being a big fan of that football team.And if your mom loves to read,you just might grow up carrying a book wherever you go,just like she does.

    Here are four ways you can stay.close:and build a strong relationship with your parents.

    ⑴Spent time together.How much time do you spend just enjoying each other's company?

    Instead of playing a computer game or watching TV,maybe you can ask your mom and dad to play with you.Go outside together,try a board game,or read a book out.

    ⑵Share your feelings and ask for help.Your mom or dad might not know that you're having a problem.Tell a parent if you're sad or struggling with something.

    ⑶Show your care. Some families are always kissing, hugging, and saying "I love you". It's important to show that you care for each other. In addition to kisses and hugs, kids and parents show their love by respecting each other, being caring, polite, and thoughtful.

    ⑷Whatever you do, do your best! You, don't have to be perfect, but when you do your best, you make your parents proud. It makes them happy to see how you're turning into such a great kid. Why? Because it lets them know they're doing a good job.

    Many facts suggest that children are overweight (超重的) and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

    Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

    There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

    There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

    The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.

Look for tigers in India, or take an elephant safari in Sri Lanka. We use local guides and stay in a range of accommodation, from tents to trees houses.

    When it comes to climate change, there are always some new, terrifying consequences to worry about—like ancient viruses and bacteria coming from the ice as the earth warms. Unfortunately, researchers fear we may see more of this in the future.

    Some of these viruses and bacteria may have been trapped for thousands of years, and it's not even totally clear yet what they are, let alone what kind of damage they might have.

    Researchers have met complex “giant viruses” in the melting permafrost(永久冻土) of Siberia. One such virus, 30,000 years old, was still infectious when it was discovered in 2015, though it posed no danger to humans. It turns out that permafrost is excellent at preserving bacteria and viruses that are temporarily inactive, and then become reactivated with warming.

    Scientists have discovered Spanish flu viruses in dead bodies buried in 1918 in the Alaskan tundra (冻原). When close to half of the population of a Siberian town in the 1890s died of smallpox (天花), their bodies were buried in the permafrost along the Kolyma River. The banks of that river are now beginning to wear away amid global warming, the BBC reports.

    In Siberia in August 2016, some 100 people and 2,300 deer were infected with anthrax(炭疽) in the first outbreak in the area since 1941. One boy died from the disease. Scientist believed the anthrax had been trapped in the body of a long-frozen dead deer and became active during particularly hot summer of 2016, releasing the bacteria cells into the environment.

But even in warmer climates, rising temperatures can help grow and spread dangerous diseases. Over a decade ago, researcher Paul Epstein prophesied the possible spread of mosquito-born illnesses as a result of climate change. “Mosquitoes are sensitive to temperature changes,” he said. “Warming speeds up their rates of reproduction and the number of blood meals they take, makes their breeding (繁殖) season long, and shortens the maturation period for the germs they spread” — all of which makes them more efficient at spreading disease.

    Bees in a colony work with each other to gather food, and they try to find the most nectar (花蜜)in the least amount of time possible. A small number of bees work as searchers, but when a good flower patch (花丛) is found, how do they tell other bees where to find it?

    Bees communicate flower location using special dances inside the hive, where bees live. One bee dances while the other bees watch. The dancing bee smells like the flower patch, and also gives the watching bees a taste of the nectar she has gathered. Smell and taste helps other bees find the correct flower patch. Bees use two different kinds of dances to communicate information: the waggle (摇摆) dance and the circle dance.

    Waggle dance

    The waggle dance tells the watching bees two things about a flower patch's location: the distance and the direction away from the hive.

A. Distance

    The dancing bee waggles back and forth as she moves forward in a straight line, then circlesaround to repeat the dance. The length of the middle line, called the waggle run, shows roughly how far it is to the flower patch.

B. Direction

    Bees know which way is up and which way is down inside their hive, and they use this to show direction. How? Bees dance with the waggle run at a specific angle away from straight up. Outside the hive, bees look at the position of the sun, and fly at the same angle away from the sun.

    Circle dance

    The circle dance tells the watching bees only one thing about the flower patch's location: that it is somewhere close to the hive.

    In this dance, the bee walks in a circle, turns around, then walks the same circle in the opposite direction. Sometimes, the bee includes a little waggle as she's turning around. The duration of this waggle is thought to indicate the quality of the flower patch.
