A lot of people like keeping pets. The most common pets that are {#blank#}1{#/blank#}(keep) throughout the world are cats and dogs. The following are the major advantages of keeping pets. Pets {#blank#}2{#/blank#}dogs need regular walking and exercise for proper development. As you take your dog out for {#blank#}3{#/blank#}walk, you are also going to exercise your whole body. In fact, dog owners spent a lot more time {#blank#}4{#/blank#}(walk) compared to other people.

    {#blank#}5{#/blank#}sharing your problems and difficulties with good friends is good, research shows that spending some time with your pets might be more useful . Also, when doing {#blank#}6{#/blank#}(difficulty) things, people experience less stress if they have their pets with them. This could possibly be because pets do not question or judge their {#blank#}7{#/blank#}(own); they simply support them. People who walk with their pets, especially dogs, {#blank#}8{#/blank#}(be) more welcoming and it gives them something to talk about with other people.

    Keeping pets has various advantages, but {#blank#}10{#/blank#}also has some disadvantages. Pets come with extra work and this can cause stress to the owners.

    Waste can be seen everywhere in the school. Some students ask for {#blank#}1{#/blank#} (much) food than they can eat while others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don't {#blank#}2{#/blank#} (agree) with them. Waste can bring a lot of problems. Although China is rich in some resources (资源), we are short of (缺乏) others, such as fresh water (淡水). It is {#blank#}3{#/blank#} (report) that we will have no coal (煤) or oil to use in 100 years. So if we go on {#blank#}4{#/blank#} (waste) our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students {#blank#}5{#/blank#} waste things every day .Everybody should stop wasting as soon as {#blank#}6{#/blank#} (possible). In our everyday life, we can do many things to prevent waste {#blank#}7{#/blank#} happening. For {#blank#}8{#/blank#}, turn off the taps(水龙头)  when we finish washing. Turn off the lights when we leave the classroom and try not to {#blank#}9{#/blank#} (order) more food than we need little by little, everything will be changed. {#blank#}10{#/blank#} (waste) can be stopped one day if we do our best.
