关于南美洲的叙述，正确的是

    Charlie was about to climb into bed when he found there was a light on in his garden shed(棚). Then he noticed some people who were busy stealing his things.
    He call the police right away. The policeman asked, “Are there any intruders(闯入者)in your house?” Charlie replied “no” and explained what was happening.
    The policeman said, “All patrol cars(巡逻车) have gone out, and a policeman will go to your house when one is free.”
    Charlie hung up, waited 30 seconds, and then called the police again. “Hello, I just called a short while ago because there were people stealing things from my shed. I want to let you know that they're not a problem anymore because I've just shot every one of them.”
    Charlie then hung up the phone. In five minutes, three patrol cars, nearly twenty policeman and an ambulance arrived at his house. Of course, the police caught the thieves.
    One policeman said, “I thought you said that you shot every one of them!”
    Charlie replied, “I thought you said there were no patrol cars free!”

    那盆仙人球在肉质很厚的三角形茎柱上，顶着一个黄色的圆球。布满刺芒的圆球旁，绽放出一朵橘红色的小花，美丽极了，长长的花蕊上还有点点花粉呢！我看它就像一位快乐的小天使，举起一束火炬。仙人球只要一撮泥土，没有任何苛求，四季长青，给人以美的享受。它祖祖辈辈生活在沙漠里，高温锻炼了它的体魄，风沙培养了它的坚韧，它是大自然抗御逆境的骄子。
