pass
1.pass an ocean, pass a desert, pass a frontier, pass a boundary, pass a mountain range等表达方式里的pass都作“穿过”或“渡过”解。但pass a city, pass a street, pass a lane等表达方式里的pass都作“在…的旁边经过”解。说“路过（城市）”该说pass through，说“在（街道或弄堂）里经过”该说pass through或pass along。例如：As I passed through Shanghai, I bought some books at a bookshop in Fuzhou Road.和Passing through（或along）the street, he met an old friend.不可说As I passed Shanghai, I bought some books at a bookshop in Fuzhou Road，因为passed Shanghai是“在上海的旁边经过”，并不进入上海，当然不能到福州路的书店买书。
2.pass an examination是“在一次考试里及格”，不是“参加一次考试”或“完成一次考试”。
3.He has passed the examination里没有in，但在He has passed in English和He has passed in all the subjects里的in用的多，不用的少。
4.pass用作“死去”解现在极不普通，该避免。说“死去”该用pass away或pass on。
5.pass over不可用作“读过”解，I have passed over the passage是“我已经忽略了这段文字”。不是“我已经读过这段文字”。
6.pass on...to是“把…传递（或转告）给…”。例如：I told Mr Read that I should be very glad to pass on his request to you.
7.注意下面各句的结构：
- Those times have passed away.（have passed属于完成时态）
- Those times are passed away.（passed是不及物动词的过去分词，用作形容词）
- Those times are past.（past是形容词）
