Lizards have a simple body shape. They have a head, a pair of legs, a long body, another pair of legs and a tail. Their tails can help them balance, swim, or grab tree branches. Some lizards use their tails as a weapon. They can also wiggle away from a predator which grabs their tail. Certain muscles will cause it to fall off, but the tail still moves. The predator watches the tail, and the lizards can escape. Then lizards can grow a new tail. Lizards range in size from one and one-half inches long to seven and one-half feet. The Komodo dragon is the biggest lizard. The Komodo dragons live in Indonesia. The smallest lizards live in the British Virgin Islands.
蜥蜴的体型十分简单。他们有一个头,一双腿,一个修长的身体,另一对腿和一根尾巴。它们的尾巴能帮助他们平衡,游泳,或抓住树枝。有些蜥蜴用它们的尾巴作为武器。当捕食者抓住他们尾巴的时候,他们可以通过扭动尾巴进而逃跑。而某些肌肉会使尾巴脱落,但脱落的尾巴却仍然是活动的。使捕食者盯着蜥蜴的尾巴,蜥蜴便得以逃脱。不久后蜥蜴就长出新的尾巴。蜥蜴的体型从七又二分之一英尺到一又二分英寸不等。科莫多巨蜥是最大的蜥蜴。科莫多巨蜥生活在印度尼西亚。最小的蜥蜴生活在英属维尔京群岛。
Lizards can be found on every continent except Antarctica. Many live in tropical rain forests. Food is plentiful for them there. The hot damp climate allows them to maintain their body temperatures. They can be found also in deserts and other hot, dry areas. Many of the desert lizards are nocturnal. They come out in the cooler evening. Very hot weather is not good for them. Lizards that live in cold climates hibernate through the winter. Their bodies can't tolerate the cold temperatures. Also, food is not as readily available in the winter.
