I gain a lot of rewarding experiences from some social activities. Our local Community Youth Club is a very popular organization with young people in my town. I have been a member for four years now and I've taken part in a lot of interesting projects, {#blank#}1{#/blank#} include fun activities such as holiday camps and discos. We have organized sports competitions and we have even made a video.

    But it isn't all just enjoyment, we have also started doing social work to help people in our neighborhood. We {#blank#}2{#/blank#}(organize) activities for small children during the holidays. We have also formed a special support group to help young people stop{#blank#}3{#/blank#}(smoke).

    We are particularly proud of the most recent group we have created. It organizes regular visits{#blank#}4{#/blank#}the local old people's home. My class spent an afternoon at a home and everyone found the visit very rewarding. The old people there were{#blank#}5{#/blank#}(talk) and they told us their personal stories {#blank#}6{#/blank#}(cheer). During our visit, the home was filled with {#blank#}7{#/blank#}(laugh). But we realized that life wasn't always easy. Some of them were in poor health and were very{#blank#}8{#/blank#}(happy).

    Many young people like me do not live with our grandparents and we have little contact with elderly people. As a result, many young people don't know{#blank#}9{#/blank#} they are like. After this visit, my friends and I decided that we should do {#blank#}10{#/blank#} to help improve the quality of their lives.

    We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running for example, may help to protect us {#blank#}1{#/blank#}heart disease and other health problems. Running also may help you live {#blank#}2{#/blank#}(long).

    Recently, researchers studied more than 55,000 adults. About one-fourth of the adults reported running{#blank#}3{#/blank#}(regular). The study found these runners were considerably less likely than non-runners{#blank#}4{#/blank#}(die)of any form of disease, including heart disease.

    D. C. Lee and the other researchers found that speed,{#blank#}5{#/blank#} (distant)and how often one runs made little difference in{#blank#}6{#/blank#}(reduce)the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr. Lee says slower runners, and those who only ran once{#blank#}7{#/blank#}twice a week, were helped nearly as much as those who ran faster and further.

    The researchers note that their study{#blank#}8{#/blank#}(base) on the participants' answering questions over the years. The study lacked complete information on {#blank#}9{#/blank#}these men and women ate and other facts about their lifestyles.

Researchers say this missing information could have affected the results. Still they hope their findings will motivate healthy adults to start running, a bit, down the road to live{#blank#}10{#/blank#}longer life.

    Buying books on the Internet is a great way {#blank#}1{#/blank#} (save) time and money. Online bookstores offer not only new books but also used books. What's more, they are far better {#blank#}2{#/blank#} (compare) to traditional bookstores as they offer much broader kinds of books. Another advantage of shopping online is that you can also read the book reviews as well as readers' reviews to get an idea {#blank#}3{#/blank#} the book is worth buying. Online bookstores often offer great discounts to{#blank#}4{#/blank#} (attraction) book lovers with a tight budget.

    For book lovers, {#blank#}5{#/blank#} is important to get books in time, in which case they need to find a {#blank#}6{#/blank#} (rely) online bookstore that is able to provide fast deliveries.

    Here are some {#blank#}7{#/blank#} (advise) for reference when you are selecting an online bookstore. Some online bookstores are popular {#blank#}8{#/blank#} fiction books; some are for non-fiction books or novels, etc. Understanding their specialization will help you to get the right kinds of books in time. Never choose stores that offer {#blank#}9{#/blank#} (believe) cheap prices, as books that {#blank#}10{#/blank#} (sell) at such low prices could be in very bad condition.

    Traffic jams (堵塞) are a common problem in larger cities. In some cities, traffic jams get so bad during rush hour that it is sometimes {#blank#}1{#/blank#} (fast) to walk than to drive. Traffic accidents are also a problem. Sadly these problems are not easy to solve. However, a traffic system (系统) being tested in several cities in Northern Europe has led to some surprising {#blank#}2{#/blank#} (result).

    The system {#blank#}3{#/blank#} (call) "shared streets". It is a system that has very few traffic laws. As a result, shared street areas have no traffic lights or street signs. Although most people would expect this to cause the number of traffic jams and accidents {#blank#}4{#/blank#} (go) up, until now {#blank#}5{#/blank#} has been a great drop in both. One reason {#blank#}6{#/blank#} (be) that the shared streets system encourages people to be more {#blank#}7{#/blank#} (care). Without traffic rules, people slow down and pay more attention {#blank#}8{#/blank#} each other. Normal traffic systems, on the other hand, depend on signs, {#blank#}9{#/blank#} people often miss or don't follow, leading to accidents. Also, the shared streets system decreases (减少) traffic jams because without fixed (固定的) parking spaces, it is easier for cars to move around {#blank#}10{#/blank#} (free) when there is a lot of traffic.
