When you take a walk in any of the cities in the West, you often see a lot of people{#blank#}1{#/blank#} (walk) with dogs. It is still true that the dog is the most useful and faithful animal in the world. But the reasons why people keep a dog{#blank#}2{#/blank#}(change). In the old days, people used to train dogs to protect themselves against the attacks from{#blank#}3{#/blank#}beasts. And later they came{#blank#}4{#/blank#}( realize) that the dog was not only useful{#blank#}5{#/blank#}willing to obey its master. For example, when people used dogs for hunting, the dogs would not eat what they caught without{#blank#}6{#/blank#}(permit). But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery, but the {#blank#}7{#/blank#}(important) reason is for companionship. For a child,{#blank#}8{#/blank#}dog is his best friend when he has no friends to play with; for a young couple, a dog is {#blank#}9{#/blank#}child when they have no children; for old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed{#blank#}10{#/blank#}protection to friendship.

    Li Daiyu and Liu Qian were on a trip to Canada. At 8 o'clock, their friend, Danny Lin,{#blank#}1{#/blank#}(Wait) there when they appeared. On the way {#blank#}2{#/blank#}the station, they chatted about the trip. “{#blank#}3{#/blank#}(go) eastward, you'll pass mountains and millions of lakes and forests. Remember the fact{#blank#}4{#/blank#}Canada is 5,500 kilometers from coast to coast. Vancouver, in Canada's warmest part, is Canada's most beautiful city,{#blank#}5{#/blank#}(surround) by mountains.

    Skiing in the Rocky Mountains and sailing in the harbour make it one of Canada's most popular cities {#blank#}6{#/blank#}(live) in. Its population is increasing {#blank#}7{#/blank#}(rapid). Another city, Toronto, is the biggest and most {#blank#}8{#/blank#}(wealth) city in Canada. They could see the misty cloud that rose from the great Niagara Falls in {#blank#}9{#/blank#}distance. Montreal is a city with wonderful restaurants and clubs. Most of people speak both English and French. In a word,

    Canada is a {#blank#}10{#/blank#}(mix) of many cultures and races. Have a good time.”

    If you've ever heard of someone being in the right place at the right time, you've likely never heard it fit a story as well as this one. In 2014, a 17-year-old volunteer firefighter {#blank#}1{#/blank#}(call) Joseph Chambers heard {#blank#}2{#/blank#} loud crash outside of his sister's home. Joseph found two cars {#blank#}3{#/blank#}what appeared to be a fatal collision, one of {#blank#}4{#/blank#}was a police patrol car. He{#blank#}5{#/blank#}(immediate) ran up to the car of Officer Mark Kimsey{#blank#}6{#/blank#}(see)if he was okay. Officer Kimsey {#blank#}7{#/blank#}(trap), but Joseph sprung into {#blank#}8{#/blank#}(act), pulling Kimsey out through the window with another bystander as his patrol car burst into{#blank#}9{#/blank#}(flame). Maybe it was Joseph's firefighter training that allowed him to think, and act, so quickly, but it's certain that he saved a man's life that day without once{#blank#}10{#/blank#}(think)about his own well-being.

    These days, modern buildings are everywhere. But if you want to see{#blank#}1{#/blank#}life was back in the old days, China still has many beautiful water{#blank#}2{#/blank#}(town) to visit. CNN has chosen four of the country's most beautiful ones.

    The village of Zhouzhuang in Jiangsu calls{#blank#}3{#/blank#}(it) "the oldest water town in China". The village, which{#blank#}4{#/blank#}(build) in 1086, is crossed with canals. Taking a boat ride through town, the red lanterns might make you think of China's romantic past.

    Hongcun,{#blank#}5{#/blank#} (fill) with lakes and beautiful Anhui-style buildings, is 900 years old. It was built to look like a big ox. Huangshan Mountain is the head; the town is the body and the bridges are legs.

    Fenghuang in Human doesn't look like a bird,{#blank#}6{#/blank#}its name means "phoenix" (凤凰) in Chinese. The town is as beautiful as the{#blank#}7{#/blank#}(magic) bird. The stilted (吊脚的) buildings on each side of the Tuojiang River make the area look like a scene from{#blank#}8{#/blank#}postcard.

    While most water towns are in the south, Shangdong's Tai'erzhuang stands out in the north. The town{#blank#}9{#/blank#}(be) on the bank of the Beijing-Hangzhou Grand Canal. In the town, there are ancient bridges, a canal and temples,{#blank#}10{#/blank#} (make) you think of its past glory.
