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.

  (3)go by还可意为"根据……作出判?quot;。e.g.
  Going by her clothes,she must be very rich.从她的衣着来判断,她很有钱。
  go by 与 pass by,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。
  ③He passed by me without noticing me.他从我身边走过而没注意到我。

  (3)go through还可作"遭受,经历,忍受"解,及物性短语动词。e.g.

  ①She always talks to me as though/if she were/was my sister.她总是以我妹妹的口气跟我说话。

  (2)句中belong to意为"属于",及物性短语动词。注意此词组无被动浯态,无进行时态。e.g.
  That dictionary belongs to me.那本辞典是我的。
  注意此词组还可意味"是……的一员,与……有关联"。e.g.
  I belong to the tennis club.我是这个网球俱乐部的会员。
  (3)句中share...with意思是"与……共用,分享,分担"。e.g.
  ① The boy shared his toy with other children.那男孩把他的玩具拿出来,和其他小孩子一起玩。
  ②Would you share your newspaper with me?我们-起看报好吗?
  share...with与share...between/among 的区别:
  share...with意思是"与……分享,共用,分担",而share...between/among是指"在……之间分配,均分"。如果所分配范围"在……之间",是几个单数名词,则用between;如果是复数名词,between和among都可以。e.g.
  ① He shared his property between his wife,his daughter and his son.他把他的财产分给了他的妻子、女儿和儿子。
  ② Mother is sharing the cakes among/between the boys to make sure that every boy gets some.妈妈在给孩子们分糕点以确保每个孩子得到一份。
11.Which mineral would you use to protect yourself against radium?你会用哪种矿物来保护自己不受镭的伤害呢? ,
  句中protect sb./sth.against意思是"防御,保护……使不受(伤害)",这里介词against也可换成from,即protect sb./sth.from..。e.g.
  ①A line of forts was built along the border to protect the country against attack.边界沿线构筑了碉堡,以防敌人进攻该国。
