About the importance of health, nobody can explain {#blank#}1{#/blank#} (well) than your doctor. They are the people who really know the importance of keeping fit and healthy. Every time I put on {#blank#}2{#/blank#} extra pound, my doctor will remind me about what is happening {#blank#}3{#/blank#} my body. We may look healthy but we don't know {#blank#}4{#/blank#} (clear) what is happening inside. And there are many different ways we can make sure that we are as {#blank#}5{#/blank#} (health) inside as we are outside. The first and easiest step is keeping a good {#blank#}6{#/blank#} balanced diet. Next is sleeping well. Sleep early. Make sure you get your nine hours' sleep. Do not skip your breakfast. It is one of the most important {#blank#}7{#/blank#} (meal) of the day. Exercise every day. Go for a swim, or walk, or just play football or tennis. Try your best not to have too much stress because it''s very {#blank#}8{#/blank#} (harm) to your health. Remember to keep {#blank#}9{#/blank#} (wash) your hands, and then you won't catch any infections(传染病). And getting away from your bad habits {#blank#}10{#/blank#} (be) important too.

    If you visit the animal shelter (收容所) in Salinas, California, you'll see huge signs that have a picture of a dog and a cat on them. These signs {#blank#}1{#/blank#} (put) in front of the shelter to catch people's attention. The signs make people interested in the shelter and encourage them {#blank#}2{#/blank#} (visit) it—and maybe even take a cat or a dog into their homes.

    Each year, the Salinas shelter {#blank#}3{#/blank#} (accept) thousands of dogs and cats. The animals are either lost ones {#blank#}4{#/blank#} are left by people who can't take care of them. Of all the animals, some of {#blank#}5{#/blank#} (they) are taken into new homes. Some animals are moved to other shelters to live a better life. Unluckily, some cannot be saved because they are too sick or are thought to be dangerous.

    Animal shelters provide food, medicine, and safe places for animals to sleep in. But they are not the {#blank#}6{#/blank#} (good) homes. The animals have to stay in small cages. The people who work at shelters do their best to care for the animals, {#blank#}7{#/blank#} the animals do not always get the attention or exercise they need.

    To prevent animals from {#blank#}8{#/blank#} (become) homeless, pet doctors advise the owners to take good care {#blank#}9{#/blank#} their pets. Most pet doctors also suggest people make sure their pets have {#blank#}10{#/blank#} special surgery (外科手术). In this way animals won't have more babies. And it reduces (减少) the number of homeless animals.
