Lesson 2词语辨析:
2.There was a certain mineral which was even more radioactive than uranium.
此句中的certain 是形容词,做定语,意思是"某,某一,某种,一定的",用来表达:
(1)不具体指明的某个,某些,或 知而不说的某事物,后接名词单复数形式均可。e.g.
① Water can be changed into ice or steam under certain conditions.水在一定的条件下可以变成冰或蒸汽。
②.He didn't come for a certain reason.由于某种原因,他没来。
(2) 表示一个知之不详的事物。e.g. A certain Ms Jones phoned you today. 有位琼斯女士今天给你来过电话。
certain与some 的区别:
certain , some 都可作形容词,作定语,表示"某,某个",前面说到certain 作定语表示不具体指明的某个,某些或知而不说的事物,或表示一个知之不祥的事物。而some则用来表示不确定的或不能够具体说明的某个人或某物,即不可知的某事物,只修饰单数可数名词,且不与冠词连用。e.g.
a. He went to some place in Africa. 他去了非洲的某个地方。
b. b. Some man asked to see you just now. 有个人刚才要求见你。
5. As months went by,the work seemed endless.时间一个月一个月地过去了,而他们的工作似乎并无止境。
(1)此句中go by是动词短语,意思是"(时光)逝去"(不及物性动词短语)。还可作"经过(某处)"(及物或不及物性动词短语)。e.g.
①Two years went by.两年过去了。
②We waited for the procession to go by。我们等着游行队伍经过。
③A truck went by us at full speed.一辆卡车从我们身旁全速通过。
④She let the chance go by.她错过了机会。
(2)go by还可作"依照,遵循,依据……办事"解,及物性动词短语.e.g.

,pass的区别:
(1)go by和pass by是同义短语,都可指"经过"(某处),go by是动词+副词结构,意为"从……旁边经过,经过"。pass by意为"经过,通过,从……旁边经过",指经过人或物的面前或旁边而不停顿,也不注意所经过的人或物是谁。pass意为"经过",指在人或物的面前或旁边经过,侧重经过的动作。用pass by时,侧重不加注意的意味,但在实际上,pass和pass by常被毫无区别地使用。e.g.
①The bus went by the stop without stopping.那辆公共汽车停都没停就从汽车站开了过去。
②A car went by.一辆汽车驶过去。
