Welcome to Sydney! Sydney isn't the capital{#blank#}1{#/blank#}(城市), but it is really a great place for you to take a vacation. Every year many{#blank#}2{#/blank#}(游客)come to Sydney. From the beautiful beaches to great shopping centers, Sydney has something for everyone. And it's getting more and more{#blank#}3{#/blank#}(受欢迎的).

    For outdoor or sports fans, Sydney is just right for you. The{#blank#}4{#/blank#}(空气)is quite clean and fresh there. You can do{#blank#}5{#/blank#}(令人激动的) things , just like climbing or hiking . The beautiful beaches are good for water sports. If the weather is clear, you can enjoy{#blank#}6{#/blank#}(游泳)into the sea. But of course, it is also great for you to walk {#blank#}7{#/blank#} (沿着) the beautiful white beaches and try to pick up some{#blank#}8{#/blank#}(特殊的)shells for yourself.

    If you go there, you can't{#blank#}9{#/blank#}(错过)Sydney Opera House because it is a symbol of the country. And one more good thing is that Australians are very friendly. You can{#blank#}10{#/blank#}(仍然)have a good time if you don't speak English well. So why don't you plan a trip now?

    As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is {#blank#}1{#/blank#} (必需的). Generally speaking, all living things are sure to {#blank#}2{#/blank#} (死) without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) {#blank#}3{#/blank#} (一起). They are connected in a food chain(链).

    Within a food chain， some living things are producers and some are consumers (消费者). Plants are producers because they use {#blank#}4{#/blank#}(阳光)，soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.

    There are four{#blank#}5{#/blank#} (不同的) kinds of consumers in the animal kingdom. A carnivore is an animal that only eats flesh(肉). A herbivore is an animal that only eats plants. An omnivore is an animal that eats {#blank#}6{#/blank#} (都) meat and plants. A scavenger is an animal that eats dead animals.

    Look at the picture. It is an {#blank#}7{#/blank#} (例子) of a food chain. The food chain {#blank#}8{#/blank#}(显示) the order that animals eat each other in a community. In the picture, you can see what animal or plant is food for {#blank#}9{#/blank#} (另一个) animal. See? A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. {#blank#}10{#/blank#} (用) this way, all of these living things are connected.

     Hello, everyone. I'm Mike from Canada. I am thirteen. I have a good{#blank#}1{#/blank#} (朋友). Her name is Cindy. She is in the same class as me, so we are {#blank#}2{#/blank#} (同学).

     I have a soccer ball. We often {#blank#}3{#/blank#} (踢) it after school. Cindy has a tennis ball,{#blank#}4{#/blank#} (但是) she doesn't have tennis {#blank#}5{#/blank#} (拍). I have two. So we also play tennis together.

     Today is Cindy's birthday. There's a big party(聚会) in her house. I go there and give her new basketball as a present(礼物), She is very

Happy to {#blank#}6{#/blank#} (获得) it. All her friends come to her house. We eat a lot of food. We eat some fruit like apples,{#blank#}7{#/blank#} (香蕉), oranges and pears. As for {#blank#}8{#/blank#} (蔬菜), we eat carrots and tomatoes. Cindy likes chicken very much, but she doesn't {#blank#}9{#/blank#} (吃) it too much. because she doesn't {#blank#}10{#/blank#}(想) to be a fat girl.

    We are so happy at the party.
