六级词汇讲解:
本句的主干是Melina Kunar...and Todd Horowitz...ran...experiments...。其中,in which two groups ofvolunteers...to driving属于介词+关系代词引导的定语从句,修饰先行词experiments,该从句中又包含一个that引导的定语从句,修饰先行词moving tasks。
reckon意为认为,此外它还含有考虑;估计之意。如:
I have to reckon the cost before I book the tickets.
我得先算一下费用,然后再订票。
equivalent意为相等的;相当的。如:
This qualification is equivalent to a degree.
这个资格证书相当于学位证。
英语六级考点归纳
由介词+关系代词引出的定语从句须注意以下几个问题:米关系代词which和whom在定语从句中作介词的宾语时,介词可放在关系代词之前,也可放在该定语从句中的动词之后(此时,which可用that代替,whom可用who或that代替。在口语和非正式文体中,关系代词可以省略)。如:
Im looking for afriend with whom I can chat on msn.
我在寻找一个能和我用msn聊天的朋友。
此句可以改为:Im looking for afriendI can chat on msn with.
关系代词that在定语从句中作介词的宾语时,介词只能放在从句中de相关动词之后,不可放在that前面,但that可省略。如:
The position she applied for is very attractive.
她申请的那个职位很有吸引力。
The position for that she applied is very attractive.在由代词+ of+关系代词结构引导的定语从句中,先行词指人时用whom,指物时用whicho如:
There are 50 students in my class,most ofwhom are girls.
我们班上有50个学生,其中大多数是女孩。
He has a large coUection ofbooks,many ofwhich are written in English.
他藏书很多,大部分是英文书。
