Running a few kilometers each day is good for our health. However, new research says running too much could be bad for us. Running long distances {#blank#}1{#/blank#}(regular) for many years could make our life{#blank#}2{#/blank#}(short), not longer. The study is from the Minneapolis Heart Institute. A researcher said too much running can created plague(斑) inside your heart,{#blank#}3{#/blank#}can lead to heart disease. He wrote that running too much for many years takes away the good things from exercise. He{#blank#}4{#/blank#}(add) that the risk of heart disease could be{#blank#}5{#/blank#}same as someone who never exercised.

    Researchers looked{#blank#}6{#/blank#}the health and training of 3,300 runners over the age of 35. 70% of them ran over 30 kilometers a week. Men who ran marathons for 25 years had 62% more plaque in their heart than men who did little{#blank#}7{#/blank#}no exercise. Another doctor said he felt cheated. He started running marathons in 1967. He used{#blank#}8{#/blank#}(run) 60 kilometers every week. He said, “I thought I was out there exhausting{#blank#}9{#/blank#}(me), building an absolutely strong heart.” The doctor advised{#blank#}10{#/blank#}(exercise) frequently but not to overdo things.

    Taking your pet for a walk should be {#blank#}1{#/blank#}enjoyable experience, not one which leaves your arms {#blank#}2{#/blank#} (pain) after your dog running too far away, reaching the end of the dog leash (狗绳). Some dogs{#blank#}3{#/blank#} (simple) will keep trying to pull {#blank#}4{#/blank#} (them) away from the leash, and {#blank#}5{#/blank#} (depend) on the size of the dog, this can cause much pain to your arms.

    Now there is a tool{#blank#}6{#/blank#} (call) the Dog Trainer which will probably solve these dog walking issues. For $39.95, the special invention is designed to help train your dog {#blank#}7{#/blank#} you go out for walks. The tool is fixed with the leash, and whenever it senses a struggle, it will send a noise which only your dog will be able to hear, thus forcing it {#blank#}8{#/blank#} (realize) that struggling is not worth it!

    The noise becomes{#blank#}9{#/blank#}(loud), based on the force of the struggle, and it has four sound levels. The Dog Trainer is powered by two AAA batteries (电池) and we believe if you have a large dog{#blank#}10{#/blank#}likes to try and escape all the time, then this handy little invention is surely worth the small payment.

    People often have trouble {#blank#}1{#/blank#} (get) used to a new culture because they need a long time to adapt to it. They are usually curious {#blank#}2{#/blank#} they first arrive in a foreign country and sometimes they may get confused about what to do. However, if they stay for {#blank#}3{#/blank#} long time, they may start to feel different {#blank#}4{#/blank#} (stage) of culture shock. They can feel lonely or sad because they can't deal with the local people. How {#blank#}5{#/blank#} (quick) people get used to culture differences may depend on the way they {#blank#}6{#/blank#} (learn). That's a problem if they can't speak the language. So the first important thing is to learn to speak the local language. On {#blank#}7{#/blank#} other hand, some can study the situation and make good guesses about the culture. When they finally begin {#blank#}8{#/blank#} (understand) some of the language and make some new {#blank#}9{#/blank#} (friend), they will gradually enjoy themselves and feel {#blank#}10{#/blank#} (comfort). Then they can live an easy life in a completely new culture.

    The visit of President Xi Jinping to Britain shows the more frequent communication between China and Britain. The cultural differences between the two countries have caused a heated {#blank#}1{#/blank#} (discuss).

    Table manners are the important process in our daily life. We get used to using chopsticks {#blank#}2{#/blank#}Englishmen use knives and forks. It's impolite{#blank#}3{#/blank#} (laugh) when you are eating in Britain, which suggests you don't respect others{#blank#}4{#/blank#} the contrary, we laugh and talk during a meal. What's more, in Britain, people have to drive along the left side of the road, but traffic in our country{#blank#}5{#/blank#} (keep) to the right. Besides, for Chinese students, what they have experienced in studying is {#blank#}6{#/blank#}organized learning way. Students are asked to follow a clear plan.

    {#blank#}7{#/blank#} (compare) with Chinese education, British education is flexible and {#blank#}8{#/blank#} (imagine). Students there are encouraged to discuss the subject they want to learn. Last but not least, in China, “Thank you” is not frequently used between friends and family members. However, “Thank you” is{#blank#}9{#/blank#}(wide) used in Britain.

    There is no sense in debating{#blank#}10{#/blank#}is better. We owe these manners to the different history, but you should do as the Romans do.

    I am looking at an old friend of mine.

    He has been one of my best{#blank#}1{#/blank#}(friend )for almost 12 years. He has blessed my life with his loyalty, kindness{#blank#}2{#/blank#}(wise) and love since the day when I first met him{#blank#}3{#/blank#}doesn't matter to me that he has four legs instead of two, fur instead of clothes, and barks at me instead of talking to me.

    As I watch my friend sleeping{#blank#}4{#/blank#}the sun, I cant help{#blank#}5{#/blank#}(think) of all the goodness he has brought into my life. He has been with me every day through good and bad times. He has always been my protector. He has always reminded me that I am loved and showed me how{#blank#}6{#/blank#}(love)others at the same time.

    My friend has aged far{#blank#}7{#/blank#}(quickly)than me and had more and more health problems over the years. I am not sure how long we will be together before he {#blank#}8{#/blank#}(pass)away from this world.

    This {#blank#}9{#/blank#}(wonder)dog has helped me understand that you don't have to be perfect to be loved and{#blank#}10{#/blank#}poor health and old age might affect the body but they don't have to decrease the spirit.

    Once a group of 50 people was attending a seminar. Halfway through his talk, the speaker stopped and decided {#blank#}1{#/blank#} (create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon {#blank#}2{#/blank#} (use) a marker pen. Then all the balloons were {#blank#}3{#/blank#} (collect) and put in another room.

    The speaker then led the group to the room full of balloons and asked them to find the balloon {#blank#}4{#/blank#} had their name written on, within five minutes. Everyone was {#blank#}5{#/blank#} (hurried) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find {#blank#}6{#/blank#} (them) own balloon.

    Now each person was asked to randomly collect {#blank#}7{#/blank#} balloon and give it to the person whose name was written on it. Within two minutes everyone {#blank#}8{#/blank#} (have) their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly what was happening in our {#blank#}9{#/blank#} (life)．Everyone is hurriedly looking for happiness, and not knowing where it is.

    Our happiness sometimes lies in the happiness of other people. Give them happiness {#blank#}10{#/blank#} you will get your own happiness.
