across、over、through区别.doc

词语辨析across 、over、through在英语考题中，经常出现单词“across”，“over”和“through”，它们都有“穿过”的意思，但其用法有如下区别：. “across”介词，意为“横过”，常指从这边到另一边，即：“from this side to the other”，图形好像“十”字。例如：1. The bus is coming across the bridge.2. They often go to school across the street.3. Can you swim across the river ?例：The child will go _ the road after the light turns green.A. through B. across C. over D. out二该题考查“越过马路”，应用“across”一词，指从一边到另一边，故答案为B。. “over”既可用作介词又可用作副词，意为“越过、翻越过去”。例如：1. After they climbed over the hill , they found many flowers in the fields.2. Jack told me that he could jump over the desk .3. He spoke to me over his shoulder.例：They can”t climb _ the mountain if they can”t keep going.A. on B. through C. over D. across三根据题意：“他们如果不坚持下去就不可能越过这座山”。显然，他们既不可能“穿越”这座山，也不可能“横过”这座山，而是要“爬过”这座山。故答案为C。. “through”介词，意为“从中间穿过”。例如：1. The deer is going through the forest.2. The balloon is flying on and on through the clouds.3. Jack saw many students playing on the playground through the window.例：Tom and Jack saw a fox when they were walking _ （穿过）the forest. 该题主要考查“穿过森林”，表示从中间穿过，所以答案为“through”。 across/through两者都可作介词,都意为“穿过”，但是用法不同：1)across 着重指从一物体表面的一边、一面到另一边、另一面。例如：Can you swim across the river in ten minutes?I helped the blind man across the road.2)through 着重指从空间的一头穿到另一头，也就是说从一个物体的空间里穿过。例如:The river flows through the city.The road led through the trees to the river. over,through,across的区别，最好举例子over是从物体表面上方经过，不与物体接触例如：The bird flew over the river。鸟从河水表面飞过throngh是从物体中穿过，例如：The elephant cant go through the gate.这头象不能从门里穿过。across从物体表面经过并且有接触The car is going across the brige汽车正从桥上经过over和across和区别1)over和across都可用来表示“向(或在)某一长形物体如街道、马路、河流的另一边。”We walked over/across the road. 我们走过马路。He lives just over/across the river? 他就住在河对面。【注意】over可用于水面上动作，不能用于水中动作。How long will it take to swim across the river?游过这条河需要多久。(不能用over)。2)over和across都可用来表示“在某一高形物体的另一边”，表示状态。If we can be over/across the mountain before sunrise, there will be hope to win. 如果日出前我们能翻过那座山，就有希望获胜。【注意】表示“越过”某一高形物体，用over与动词搭配，不用across。When I saw him, he was climbing over the fence.我看到他时，他正翻过围墙。(不用across)3)across可用来表示从某一范围的一边到另一边，如田野、沙漠、房间等。It took him six weeks to walk across the desert.他花了六个星期走过沙漠。(不用over)He walked across the room, smiling strangely.他走到房间的另一边，脸上挂着令人捉摸不透的微笑。(不用over)初三中考专题1.
