Make yourself know the type of  {#blank#}3{#/blank#}  you are standing on. Wet or uneven（不平坦的）ground can cause you to {#blank#}4{#/blank#}  down in a crowd of moving people.

 If you find {#blank#}5{#/blank#}   in the middle of a moving crowd, you must be careful. Do not walk {#blank#}6{#/blank#}  the moving direction and do not stop or sit down, because you could get trampled (踩踏)  {#blank#}7{#/blank#} Instead, move in the same {#blank#}8{#/blank#}  of the crowd. Keep your{#blank#}9{#/blank#}  up by your chest（胸部）to protect your chest. If you fall down, get up quickly, If you can't get  {#blank#}10{#/blank#}  , ask someone to pull you back up. If you have kids, lift  {#blank#}11{#/blank#}  up.

 If you fall and cannot get up, keep on  {#blank#}12{#/blank#}   in the same direction of the crowd. If that is not  {#blank#}13{#/blank#}   , then cover your head with your arms.

 Try to get away from hard things in a crowd. If you're pushed against them, {#blank#}14{#/blank#}   a result, you may be hurt badly.

 We should learn to {#blank#}15{#/blank#}  ourselves. Stay away from the crowd.

Remember: Whatever you do, safety is first!

Why are some animals pets and others lunch?

    In some countries, dogs and cats are commonly considered as pets, while chickens, ducks, and {#blank#}1{#/blank#}(猪) are food. However, in some other countries dogs and cats are food, and the food animals are pets.

    People {#blank#}2{#/blank#}(分开,将……分成) animals into several kinds to their own needs. For example, you may have{#blank#}3{#/blank#}(朋友) who keep rabbits as pets. Some people {#blank#}4{#/blank#}(烹饪) rabbits as dishes. People treat a rabbit as a pet because it {#blank#}5{#/blank#} (带来) them pleasure. They eat it, for they think it is a kind of meat. They kill it because they believe it is  {#blank#}6{#/blank#} (有害的) to plants or people.

    People also treat animals differently based on their own cultures. Most of us have dogs as pets. Dogs live in our house, like a {#blank#}7{#/blank#}(成员) of the family. However, in some cultures, dogs are considered unclean. People{#blank#}8{#/blank#}（几乎不）ever keep them as pets. In some parts of Southeast Asia, dogs are on the menu. {#blank#}9{#/blank#}（百万）of dogs are killed every year.

    What's {#blank#}10{#/blank#}（正确的）and wrong in the way we treat animals?

    The first thing people notice about other people is the way they look. If you look clean, people{#blank#}1{#/blank#}(feel) as if you are a hard-working person. A nice look shows that you value{#blank#}2{#/blank#}(you). A nice look doesn't mean you have to spend a lot of money{#blank#}3{#/blank#}clothes or accessories(配饰). Someone can look uncomfortable in{#blank#}4{#/blank#}expensive suit if they don't brush their hair or clean their clothes. Someone else can seem to be good-looking in an old shirt and pants that has been cleaned. Besides, it's also important {#blank#}5{#/blank#}(consider) if your look is suitable for the situation. You may look lovely in your party clothes or feel {#blank#}6{#/blank#} (confidence) in your business suit,{#blank#}7{#/blank#} these would look out of style in a more casual(随便的) situation such as at a picnic or at the movies. It's important to be comfortable in {#blank#}8{#/blank#} you're wearing, but you also need to fit in with what other people will be wearing. Wear suits for {#blank#}9{#/blank#} you and the situation best: jeans and T-shirts are fine for friends and {#blank#}10{#/blank#} (movie); a nice shirt and pants are more suitable for work.

    In some ways American families are very different from Chinese ones, but in other ways they are the{#blank#}1{#/blank#}. For example, American families enjoy family dinners, support and love each other just as Chinese families do.{#blank#}2{#/blank#} many Chinese students are surprised to learn that American teenagers are allowed to make many{#blank#}3{#/blank#}on their own, and the parents want their children to leave home at eighteen, because they think their children have grown {#blank#}4{#/blank#} This is different from China.
