1. as作为连词可引导方式状语从句,意为“象……一样”，例如：Remember, you must do everything as I do. 记住，你们务必照我的样子去做每一件事。But Americans still talk about “fall” just as people do in some parts of western England. 但是美国人还是说 “fall”，就象英格兰西部有些地区的人现在说 “fall” 一样。2. as作为代词, 通常以the same…as，such…as或as…as…的形式引导定语从句，as在定语从句中作主语、宾语或表语，例如：作主语：As is known to all, coal is first discovered in China. 众所周知，煤是最先在中国发现的。作主语：As many people as were present knew the news. 在场的人都知道这条消息。作主语：Repeat this as often as is necessary. 重复做这种动作的次数视需要而定。作宾语：Such people as you mention are rare nowadays. 你提到的那种人如今很少了。作表语：He is not (= no longer) the same man as he used to be. 他再也不是从前的他了。3. as意为“当……”，引导时间状语从句；as强调主句动作与从句动作同时发生，通常译为“一边……一边……”，例如：
