认识昆虫

There are many kinds of insects livingall around us. Ants are insects. So are crickets and mosquitoes. So are butterflies and bees.

我们周围生活着各种各样的昆虫。蚂蚁是昆虫，蟋蟀和蚊子是，蝴蝶和蜜蜂也是。

Insects come in many shapes, sizes, and colors. They don't all look alike, but there's a way to tell if somethingis an insect. Count its legs. Count howmany parts make up its body.

昆虫有各种颜色、形状、和大小，看起来并不完全相同，不过有个小窍门来辨别是不是昆虫，数一数它有几条腿，身体是由几个部分组成的。

Is a ladybug an insect? All insects have external skeletons. You have a hard skeleton inside, withparts that move. Your skeleton holds youup and helps give your body its shape. But an insect has a hard skeleton onthe outside, wih parts that move. Theskeleton is like a shell around its body. It holds the insect up and gives its bodyits shape. A ladybug has an external skeleton. Does that mean it's an insect?

瓢虫是昆虫吗?所有昆虫都有外骨骼。 你的身体里有一副坚硬的骨骼，跟随身体移动。你的骨骼能够支撑身体，保持体形。而昆虫有一副坚硬的外骨骼，跟随身体移动，像贝壳一样包着它的身体，支撑身体，保持体形。 瓢虫有外骨骼，那意味着它是昆虫吗?

Maybe not. All insects have external skeletons, but not all animals with external skeletons areinsects. Crabs, lobsters, shrimps, and scorpionshave external skeletons too, but they are not insects.

不一定哦，所以昆虫都有外骨骼，可不是全部有外骨骼的动物都是昆虫。螃蟹、龙虾、对虾、蝎子也有外骨骼。可它们不是昆虫。

Many insects have two pairsof wings and a pair of antennae. Sometimes the antennae are long, like those of crickets or butterflies. Sometimes they are short, like those of beetles,

许多昆虫都有两对翅膀和一对触角。有些触角长长的，像蟋蟀和蝴蝶的；有些短短的，就像甲虫一样。
