cross-across与through的区别.doc

cross, across与through的区别cross 作动词用，“穿过，越过”的意思。主要表示在物体表面上横穿。如横过马路、过桥、过河等，与go across同义。例如，Be careful when you cross the street.过马路时要小心。 Cross (Go across )the bridge, and you will see a big buiding. 过这座桥你就会看到一栋大楼。cross除了作动词外，还可作名词，是“十字架，十字形饰物”的意思。作名词时，它有较强的构词能力，它所构成的词的某些词义和用法是值得注意的。比如crossroads是“十字路”或“十字路口”的意思，它的前面可以用a，但-s是不能丢掉的。The accident took place at a crossroads.车祸发生在十字路口。因为crossroad是基督教的用语，指“十字架的道路”，不是十字路口。十字架的道路表示基督徒在信奉基督时要愿意为宗教牺牲，对信徒而言，这是一条很难走的道路。另外，crossing是“渡口”、“横道线”或“（铁路与公路的）交叉点”。The Star Ferry Pier is a ferry crossing in central.天星码头是在中环的一个渡口。All car should stop at the zebra crossing.所有车辆都要在斑马线前停下。A bus ran into a train at the level/grade crossing.一辆公共汽车在平交点与火车相撞。across是介词，有“横跨，横穿，穿越”之意。例如，The Great Green Wall is across the northwest ofChina.绿色长城横跨中国西北。across与go/walk等动词连用表示“穿过，越过，横穿”的意思。与cross基本同义，也是表示从物体表面经过。 例如，Go across the road , you will find the post office on your left. 横过这条公路，你会发现邮局就在你的左边。through是介词，“在.之中，透过”的意思，常与go, walk等动词连用，表示“穿越，横穿”等意思。主要表示从物体内部穿过。如穿过森林、隧洞等。例如，The two friends were walking through the forest.这两个朋友正沿着森林走。The sunlight comes through the glass.阳光透过玻璃。练习：1.
