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.

    Global warming has caused a rise in sea levels,{#blank#}1{#/blank#}has increased the amount of salt in fresh water used on seaside farms. As a result, farmers are{#blank#}2{#/blank#} (increase) unable to use fields close to the sea.{#blank#}3{#/blank#}a farmer in the Netherlands is now using a mixture of sea and fresh water {#blank#}4{#/blank#} (grow) tasty vegetables.

    It is in his eight areas {#blank#}5{#/blank#}he teamed up with scientists such as George Hambley to make the first attempt. Separate {#blank#}6{#/blank#} (pipe) pumped mixed water. And a computer program controlled the levels of salinity and water{#blank#}7{#/blank#} (call) “Sensor”. The researchers said they were able to harvest vegetables from most of{#blank#}8{#/blank#}eight test areas. They said the vegetables were smaller than{#blank#}9{#/blank#}grown in fresh water. However, due to more sugar and salt in the water, they taste{#blank#}10{#/blank#}(good).

    The earth was just {#blank#}1{#/blank#} cloud of dust after the “Big Bang”. The earth exploded {#blank#}2{#/blank#}(loud) with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were {#blank#}3{#/blank#}(make) the earth's atmosphere. As the earth cooled down, water began to appear on its surface. It allowed the earth to dissolve {#blank#}4{#/blank#}(harm) gases. Then life began to develop.

    Small plants multiplied and filled the oceans and seas with oxygen. This encouraged the {#blank#}5{#/blank#}(develop) of early shellfish and fish. Land animals such as insects, reptiles and dinosaurs {#blank#}6{#/blank#}(appear) after green plants came into being. Small clever animals spread all {#blank#}7{#/blank#} the earth. They are putting too much carbon dioxide into the atmosphere, {#blank#}8{#/blank#} prevents heat from escaping from the earth into space. {#blank#}9{#/blank#} life will continue on the earth for millions of years to come will depend on whether this problem can {#blank#}10{#/blank#}(solve).

    Questioning can lead to searching for an answer. If we are in the habit of asking whether that we are told is true, we can find the correct answer and learn more.

    Two years ago, our teacher, Mr. Alex offered us an answer of a difficult math problem in class. Because the answer seemed a little strange, nobody but I doubted it. Thought that his solution might be wrong, I carefully analyzed the problem and try to work it out in a different way. Half a hour later, I managed to find the correct answer. When I showed my answer to her, the teacher praised me for my dependent thinking.

    From this experience I have been learnt that questioning can serve as a bridge helps us to seek the truth.
