4.through／across／cross／past across的含义与on有关，表示某一动作是在某一物体的平面上进行，其意思是“横过”。e.g.We walk across the road.
cross=go across cross是动词，而across是介词。
through的含义与in有关，表示动作发生在立体空间，是从内部穿过。e.g.He walked
through the forest／village.
past可作副词或介词，“在……旁经过”。e.g.He hurried past me without stopping to
speak.
【考点链接】 cross／across／through／past (1)Look both ways before you________ the road.
(2)He walked_________ the field.
(3)The ball went flying_________ the window.
(4)Study some________ exam paper to get an idea of the questions.
【分析比较】 四者都有“经过，通过”的意思，但词性和用法不同。
cross意为“横过，穿过，越过，渡过”，为动词，相当于walk(go，run)across，故(1)填cross。
across意为“横过，穿过”，为介词，不作动词，不能作谓语，常放在动词之后，如：go across，walk across等。故(2)填across。另外，表示游渡，乘船过海或过河时用across。
through是介词，含有“从……中间穿越”之意，表示四周含有物体的穿越。故(3)填through。试比较：The road runs across the plain.一条路横过平原。The river
flows through the city.这条河从城市穿过。
