    Halloween（万圣节）is a {#blank#}1{#/blank#}（奇怪的）holiday. It started {#blank#}2{#/blank#}（几个的）centuries ago in Europe. It began as "Hallow Evening" which {#blank#}3{#/blank#}（意思是）"holy night". At that time November 1st was called "All Saints' Day" and people honored all the saints who did not have their own {#blank#}4{#/blank#}（特别的）day. People{#blank#}5{#/blank#}（相信）that all the spirits of dead people were active on the night of October 31st. So people would play all kinds of tricks（恶作剧）on each other.

    Black is one of the traditional Halloween colors, {#blank#}6{#/blank#}（可能地）because Halloween festivals and traditions took place at night. Pumpkins（南瓜）are a symbol（象征）of Halloween, so orange has {#blank#}7{#/blank#}（成为）the other traditional Halloween color. Making lanterns out of pumpkins is a Halloween custom.

    Halloween is great fun for children. They {#blank#}8{#/blank#}（穿衣）up as ghosts（鬼）or witches（女巫）. Small children go "Trick-or-Treating". They wear costumes, knock on door, and shout, "Trick or Treat！"People almost always choose to give them candy as a treat, {#blank#}9{#/blank#}（而不是）of choosing to receive a trick from the children. {#blank#}10{#/blank#}（成人）sometimes "trick or treat" their friends, too. Usually the "treat" is a glass of wine or some small gifts.

    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.
