2017年6月英语六级阅读必背关键句(19)

考试网   2017-06-06   【

  Melina Kunar of the University of Warwick, and Todd Horowitz of Harvard Medical School ran a seriets of experimenis in which two groups of volunteers had to pay attention and retipond to a series of moving tasks on a computer screen that were reckoned equivalent in difficulty to driving.

  华威大学的梅利娜·库娜和哈佛医学院的托德·霍罗威茨做了一系列试验,他们让两组志愿者注意电脑屏幕上的一系列移动任务并作出反应,这些任务被认为与开车的难度相当。

  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。

  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:

  I'm 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:I'm looking for afriend (who/whom/that) I 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 (that) 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.(x)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。
