Health and fitness apps are {#blank#}1{#/blank#}（广泛地）used these days. Many people are trying to lose{#blank#}2{#/blank#} (重量）or get in better shape, and technology can be very{#blank#}3{#/blank#}（有帮助的）to support them in these goals. Lots of new apps have been {#blank#}4{#/blank#}（创造）this year, and one is called “ The walk”. It is designed as a game, but the user must walk around his or her {#blank#}5{#/blank#}（自己的）neighborhood in order to play. The user plays the game the way he or she would play any video game, but as the user progresses, he or she {#blank#}6{#/blank#}（燃烧）actual calories（卡路里）.

    As the user walks throughout the day, the app {#blank#}7{#/blank#}（记录）how much ground the user has covered. The user receives a clue (提示) that is part of a story, and is told that he or she must walk a certain number of {#blank#}8{#/blank#}（分钟）to move to the next level. Once that {#blank#}9{#/blank#}（任务）has been completed, the next part of the story will be seen. Users of this app will be{#blank#}10{#/blank#}（鼓励）to take different routes in order to earn more points.

    Water is very important for living things. Without water there can be no l{#blank#}1{#/blank#}on earth. All animals and plants need water. Man also needs water. Water is found a{#blank#}2{#/blank#} everywhere. Even in the d{#blank#}3{#/blank#} part of the world there is some water in the air.

    As we all have found out, water may be a solid, or a l{#blank#}4{#/blank#} or a gas. When it is a solid, it may be as hard as a brick. When it is a liquid, you can pour it out of a c{#blank#}5{#/blank#}. When it is a gas, you cannot see or feel it. Although about 70 percent of the earth's s{#blank#}6{#/blank#}is covered with water, there are many places in the world still running out of water. So we should make good use of water on earth.
