英语中有几个表“穿过”的单词 across，over 和 through，它们的词性几乎完全一样，意思也差不多，常常让人越用越糊涂，有的时候还会犯错误，其实要把握几个重点，区分它们也不是一件难事。 一、across1. across 指在某物的另一边，或者从某物的一个边到另一边，通常该物有两个边或界限，如城市、道路、河、房间或田地等，意为“从…一边到另一边”，例如：介词：We took a boat across the river.我们乘船过河。He walked across the field.他走过田地。Across the room, she could see some old friends. She got up and went to join them.穿过房间，她可以看到一些老朋友。她起床加入他们了。副词：It's too wide. We can't swim across.这太宽了，我们游不过去。The road was so busy that we found it difficult to get across.这条路太拥堵了，我们觉得很难穿过。2. across 指触及或从一边延伸到另一边，意为“横过”，例如： I drew a line across the page.我在这一页上画了一条横线。Where's the nearest bridge across the river?过河最近的桥在哪儿？3. 在美式英语中，across from 用来指人或物体在对面或另一边，意为“在…对面”，例如：There's a school just across from our house.有一所学校就在我们房子对面。Helen’s office is just across from mine.海伦的办公室就在我的对面。4. across 强调在许多地方同时发生的事情，例如在一个组织、一个城市或一个国家内，意为“遍及，在…各处”，例如：Her family is scattered across the country.她家中的人散居全国各地。She’s opened coffee shops across the city and they’re very successful.她开的咖啡店遍及这个城市，并且做得很成功。5. across 指某事物的宽度或对角线尺寸，意为“宽”，例如：The yard measures about 50 feet across.庭院宽约50英尺。The size of a television screen is measured from the higher corner of one side to the lower corner of the other side, that is, from one corner across to the opposite corner.电视屏幕的大小是从一边的上角到另一边的下角测量的，也就是从一个角到另一个角。二、overover 指某物处于比其他东西更高的位置，有时涉及从一边到另一边的运动，例如：From the castle tower, you can see over the whole city.从城堡塔上，你可以看到整个城市。They held a large umbrella over her.他们给她撑起一把大伞。Suddenly a plane flew over and dropped hundreds of leaflets.突然一架飞机飞过，扔下数百张传单。come over 指的是到说话者家里，例如：You must come over and have dinner with us some time.你得找个时间来我们家和我们一起吃晚饭。
三、through through 表示从一个地方到另一个地方或穿过一个地点，通常是从地方或地点中间穿过，意为“从…一端至另一端；穿过，贯穿”，例如：The path led through the trees to the river.这条小路穿过树林通向河边。The Charles River flows through Boston.查尔斯河流经波士顿。四、across 和 over 的区别当 across 和 over 都用作副词时，它们的意思是一样的，指到达对面，例如：We walked over to the shop.我们走向商店。He rowed us over to the other side of the lake.他把我们摆渡到湖的对岸。五、across 和 through 的区别当表示从一边移动到另一边且在所移动的物体里面时，用 through 而不用 across，比如草场或森林里等，例如：I love walking through the forest.我喜欢步行穿过森林。When my dog runs through long grass, it’s difficult to find him.当我的狗穿过长草场时，很难找到它。六、over 和 through当谈论从头到尾的一段时间时，用 over 而不用 through，例如：我们过去四年没怎么见面。✔: We haven’t seen each other much over the last four years.❌: We haven’t seen each other much through the last four years.
