考试时,当出现类似形式的题目而确实又看不懂句子意思时,应倾向于选择which + 单数动词的那个选项。
6)They have made another wonderful discovery, ______ of great importance to science.
A. which I think is
B. I think which is
C. which I think it is
D. I think of which is
解题思路:英语中的连接词一般都是放在从句的最前面,据此,可以排除B、D选项;A、C的区分点是"it", 想一下本节的第一题,就能正确选择答案A了。此类题目中,I think应理解为"插入语",要熟悉这种形式,
又如:
He is the man ______ I suppose is capable of finishing this task.
该题应填who而不是whom
(在从句中)当状语时:关系副词where及whenwhere : 当先行名词在从句中当"地点状语"时,用关系副词where连接
例如:
The crime rate rises in cities where the unemployment rate increases. (失业率高的城市犯罪率也高。) 句中的where = in cities, 表示行为发生的地点。
这里的要点是能否区分是用that (which)还是用 where, 即:是做"主语、宾表语",还是做"地点状语",例如:
I love the small town that we visited last week.
句中"town"做动词"visited"的宾语,即"参观过的小镇",故用that连接。
I love the small town where I lived during my childhood.
句中"town" 是动词"lived"的地点,即"童年时住过的小镇",故用where.
这也是定语从句的一个考点。
when : 当先行名词在从句中当"时间状语"时,用关系副词when连接, 例如:
July is the month when we have a lot of rain. (七月是多雨的月份。)
注意"when"定语从句后推的现象,例如:
I think (that) the day will finally come when air pollution can be put under control. (我认为空气污染得以控制的一天最终会来到。)
放在主句后面作非限制定语从句时(前面一般加","号),"when"一般译为"此时","那时", 例如:
The meeting will be put off until next month, when we will have made all the preparations. (会议将推迟到下月,那时一切就准备就绪了。)
另一个关系副词是why,由于它固定与the reason搭配, 即: the reason why,不难理解,一般也不作为考试的重点。例如:
This is the reason why the electronic computer cannot entirely replace man. 这就是(为什么)电子计算机不能完全代替人的原因。
whose (= of which / whom):做医学全.在线www.med126.com先行词(不管是人还是物)的定语,汉语为"…的",不要考虑是否是限制性或非限制性定语从句, 例如:
Pay attention to that boy whose temperature is very high. (理论上也可以写成:Pay attention to that boy the temperature of whom is very high. 注意那个男孩,他的体温很高。(非限制性) / 注意那个体温很高的男孩。(限制性)
介词 + which (whom)
先看两个句子:
This is the house. He has lived in the house for over 30 years.
变为↓定语从句
This is the house in which he has lived for over 30 years.
上述句子中,先行词在从句中充当介词宾语,形成"介词 + which / whom"的形式,考试时要求作出1)要不要介词;2)若要,使用什么介词的判断。由于英语中介词搭配多为习惯用法,没有多少规律可循,因此这是定语从句考试的一个难点。
