The dog, later {#blank#}1{#/blank#} (name) Arthur, came up to a Swedish team while the members were sharing a meal in front of a 20_mile race stage through the rough area in Ecuador. One of the {#blank#}2{#/blank#} (athlete), Mikael Lindnord, took pity on the dog wandering near their table and fed {#blank#}3{#/blank#} meatball to it. And that meatball made them friends for life, as far as Arthur was concerned.

The extreme sport of adventure racing includes biking, hiking, and boating that challenge even the {#blank#}4{#/blank#} (strong) humans. Imagine a dirty stray（迷失的）dog trying {#blank#}5{#/blank#} (keep ) up. But Arthur {#blank#}6{#/blank#} (do) keep up. The dog followed the team as they got up to leave. {#blank#}7{#/blank#} (actual), he never stopped following them—swimming alongside the boat of the team, and taking on muddy(泥泞的)slopes when the team hiked.

    Arthur stayed alongside the team for the rest of the {#blank#}8{#/blank#} (compete),but not without cost to his well—being. The dog needed doctor's attention after the six-day race was finished {#blank#}9{#/blank#} the team helped Arthur as much as they could during the event. Arthur's hard work paid off: Lindnord decided to adopt(收养) the dog {#blank#}10{#/blank#} brought him back to Sweden.

During the Spring Festival in China, children {#blank#}3{#/blank#}(give) money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect {#blank#}4{#/blank#} (they) against evils.

    People's {#blank#}5{#/blank#}(choose) of colors is also influenced by their bodies' reactions toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally {#blank#}6{#/blank#} physically. When{#blank#}7{#/blank#}(work) in green environment, people have fewer stomach aches. Red can make a person's blood pressure{#blank#}8{#/blank#} (rise) and increase people's appetite. Many decorators will include different shades of red in the restaurant. And many commercial websites will have a red “Buy Now” button because red is a color that {#blank#}9{#/blank#}(easy) catches a person's eye. Unlike red, blue is believed to cause people to lose appetite. Therefore,{#blank#}10{#/blank#} you want to eat less, eating from blue plates can help.
