Li Daiyu and her cousin Liu Qian were on a trip to Canada to visit their cousins on the Atlantic coast. Rather than take the plane all the way, they {#blank#}1{#/blank#}（plan）to fly to Vancouver and then take the train from west to east across Canada. The thought that they could cross the whole continent was {#blank#}2{#/blank#}(excite).

    Canada is the second biggest country in the world. People say Vancouver is Canada's most beautiful city {#blank#}3{#/blank#}(surround)by mountains and the Pacific Ocean. On the coast north of Vancouver, it is so wet there that the trees are extremely tall.

    That afternoon aboard the train, the cousins settled down in their {#blank#}4{#/blank#}(seat). Their next stop was Calgary,{#blank#}5{#/blank#} is famous for the Calgary Stampede. They know that cowboys come from all over the world {#blank#}6{#/blank#}(compete)in the Stampede. Many cowboys have a gift {#blank#}7{#/blank#} riding wild horses. They also learned that most Canadians live within a few hundred kilometers of the USA border and that Canada's population is only {#blank#}8{#/blank#}(slight)over thirty million, but now they {#blank#}9{#/blank#}(amaze)to see such an empty country. Then they arrived in {#blank#}10{#/blank#}urban area, the busy port city of Thunder Bay at the top of the Great Lakes.

    Are you facing a situation that looks impossible to fix?

    In 1969,the pollution was terrible along the Cuyahoga River Cleveland,Ohio.It{#blank#}1{#/blank#}(be) unimaginable that it could ever be cleaned up.The river was so polluted that it{#blank#}2{#/blank#}(actual) caught fire and burned.Now,years later,this river is one of{#blank#}3{#/blank#}most outstanding（杰出的）examples of environmental cleanup.

    But the river wasn't changed in a few days{#blank#}4{#/blank#}even a few months.It took years of work {#blank#}5{#/blank#}(reduce) the industrial pollution and clean the water.Finally,that hard work paid off and now the water in the river is{#blank#}6{#/blank#}(clean) than ever.

    Maybe you are facing an impossible situation.Maybe you leave a habit{#blank#}7{#/blank#}．is driving your family crazy. Possibly you drink too much or don't know how to control your credit card use.When you face such an impossible situation,don't you want a quick fix and something to change immediately?

    While there are{#blank#}8{#/blank#}(amaze) stories of instant transformation,for most of us the{#blank#}9{#/blank#}(change) are gradual and require a lot of effort and work,like cleaning up a polluted river.Just be{#blank#}10{#/blank#}(patience).

    When kids in parts of the world want to play, they often make soccer balls out of trash tied together with string. “{#blank#}1{#/blank#} the areas used for playing fields are often rough and rocky, millions of real balls go flat (变瘪){#blank#}2{#/blank#} 24 hours,” says Tim Jahnigen, a California businessman. Determined to solve this problem,{#blank#}3{#/blank#} created an indestructible ball called the One World Futbol.

    The ball is made of {#blank#}4{#/blank#} special material, ethylene-vinyl acetate foam. It's lightweight, it's flexible, and—{#blank#}5{#/blank#} important—it holds its shape.

    The One World Futbol needs no pump {#blank#}6{#/blank#} won't wear out, even on rough surfaces. When tested,{#blank#}7{#/blank#} withstood (经受住) being crushed by a car, and even being chewed on by a lion.

    Although it costs more to produce {#blank#}8{#/blank#} a typical soccer ball, Jahnigen estimates the One World Futbol can last 30 years. So far, it's been given to kids in 143 countries. 

With the improvement of life standards, there are a {#blank#}1{#/blank#} (grow) number of people traveling each year, {#blank#}2{#/blank#} is a good way to enjoy life. Some people would like to take a package tour (跟团游), {#blank#}3{#/blank#} others would rather travel on their own. I prefer the latter, because I feel that it's much more convenient and cheaper than taking a package tour as I {#blank#}4{#/blank#} (do) before.

First of all, traveling on my own, I can arrange my time and route {#blank#}5{#/blank#} (free). For example, when I get to someplace I like, I choose to stay longer and don't have to think about others. Secondly, the schedule is relatively tight joining package tours, and tourists can only stay very short time in tourist attractions. {#blank#}6{#/blank#} is difficult to enjoy every landscape carefully. {#blank#}7{#/blank#} (three), in order to earn money, some travel agencies force tourists {#blank#}8{#/blank#} (buy) things. In the meantime, traveling on my own is much cheaper. Finally, the trip is designed to relax. However, many people say that package tours are not to make them feel really {#blank#}9{#/blank#} (relax), but even more tired.

On the whole, I feel like {#blank#}10{#/blank#} (travel) on my own, which is more convenient.
