答案：
(答案→)B
解析：这是一篇介绍公共场所标志的短文。公共场所有许多标志，我们应该了解它们的含义。不然的话就会出现麻烦。标志到处都有，了解标志非常重要。
【小题1】B细节理解题。句意：看标志B。它告诉人们。选项A. You can smoke in the hospital.你可以在医院抽烟；B. You can smoke in the hospital.你不能在医院抽烟；C. There is lots of smoke in the hospital.在医院里有许多烟；D. There is no cigarette(香烟) in the hospital.医院里没有香烟。标志B上是画的是不许抽烟的图片。故选B。
【小题2】B推理判断题。句意：你要是饿了，在街上可以找到哪个标志？从图片可以看出标志F表示吃饭，所以，答案是B。
【小题3】C主旨大意题。问题是：下面哪一句错？A. Signs are very important in our life.标志在日常生活中非常重要；B. If you see Sign C on a door, it means you can smoke in the room.如果你看到门上有标志C，意思是你可以在这个房间里抽烟；C. If you see Sign E in a place, it means you can park your car there.如果你在一个地方看到标志E，意思是你可以在那里停车；D. We usually see Sign A in a toilet.我们经常在厕所看到标志A。从图片上看到标志E是不许停车的，所以选项C错。故选C。
