解析：招牌传递信息。例如，公共汽车站的站牌告诉你要乘坐哪一辆公共汽车。学校墙上的指示牌告诉你图书馆的位置。门上牌子告诉你在哪里出入。如果看到“禁止拍照”，你就不能照相了。当你发现“危险”的牌子时，就一定要小心了。如果想过马路，就应该等十字路口的绿灯。你参观博物馆看到“保持安静”的牌子，就不要大声喧哗。你是否注意到身边的这许多的牌子和它们承载的信息呢？有必要记住一些。【小题1】which。公共汽车站的站牌告诉你要乘坐哪一辆公共汽车。Which关系代词，引导宾语从句。【小题2】library。 学校的图书馆应该用单数。【小题3】If。If位于句首，开头字母要大写。If引导条件状语从句。【小题4】photos\pictures 。No photography 这个标志的意思是你不可以拍照。photo或picture ,是可数名词，这里用复数形式表类别。【小题5】careful。careful是形容词，做be的表语。【小题6】wait。should是情态动词，后面要用动词原形。动词短语wait for意为：等待。【小题7】allowed。you aren’t 后用allow的过去分词形式，表示谓语是被动语态。【小题8】ever。现在完成时中的副词用ever。【小题9】them。them宾格，代替a lot of signs 作介词from的宾语。【小题10】remember。在这里to 是动词原形的符号。动词remember 用原形。
