through / past / across 区别 1、through / past / across 区别: 都可作介词,“穿过”,前常有位移动词(以下黑体部分)。 He climbed through the window and saw what he could take away. (从窗户内部经过) He went past me without saying any words. (从我旁边经过) He swam across the river. (从河的表面经过)【through,内部; past,旁边; across,表面】 2、位移动词 + past 有时相当于动词pass; 位移动词 + across有时相当于动词cross. 3、the number of / a number of: 前者“…的数量”;后者“许多的” 都跟可数名词复数。前者作主语,谓语用单数;后者作主语,谓语用复数。 The number of the trees is two thousand. (用单数谓语. 另注意trees前有限定词) A number of trees have been cut down. (用复数谓语. 另注意trees前无限定词) 首先是词性的区别:across为介词,而cross为动词。 (动词为“穿过,横穿”,名词为“十字,十字路口”) 2、当然across必须与through 区别开来。across为“横穿”,与“道路”交叉形成“十字”。而through为在立体空间中的“穿过”。如:go through the forest“穿过森林”,go across the street “穿过大街” ------ through表示“贯通、直穿、透过、穿过”的意思,即是从一头(边)贯穿到另一头(边)。 例The river runs through our city.这条河流经我们市。 He passed through the hall. 他穿过大厅 across表示“横穿、横过、横渡、横跨” 例:I swam across the Changjiang River 20 years ago. 20年前我横渡了长江。 Look left and right before you go across the street. 过马路时要左右看 本文来源:https://www.wddqw.com/doc/e58886916bec0975f465e2ca.html
