☆☆☆72. The number of undergraduate degrees in engineering awarded by colleges and universities in the United States increased by more than twice from 1978 to 1985. (A) increased by more than twice (B) increased more than two times (C) more than doubled (D) was more than doubled (E) had more than doubled 1 时态&语态:一级排除D,E rom 1978 to 1985 表示过去时间。 The past perfect tense in E, had... doubled, is inappropriate unless the increase in engineering degrees is specifically特定的,明确的 being viewed as having occurred further back in the past than some subsequent event. (过去完成时应该用在某事件在过去比另外一个事件发生的更早,这种时候才恰当è一定要出现明确的正确的过去时态的动作作为时间参照点) The number of undergraduate degrees in engineering awarded by colleges and universities in the United States more than doubled from 1978 to 1985.è未划线部分的时间状语是完全正确的过去时间, 用一般过去时态不要太灵啊!!!è 有个business的题目, 一样的时间, from…to…. D's passive verb was ... doubled suggests without warrant that some unnamed agent increased the number of engineering degrees. 被动语态)è怎样算with warrant: 出现by sb/ by sth. 特别是在未划线部分出现的话, 就很可能是用被动语态.
2. 词法:二级排除A,B A。twice只能作副词, 在句子中表达的意思却是比较, 这样的题目, 首先要弄清楚比较的双方是否合理, 如果合理的话, 再看twice作为副词的位置: 可以用在as..as或比较级之前, 也可以放在比较点的名词之前, 担要保证twice前后的词要能直接搭配(副词的作用). 不能做名词词性接在介词后面 by …Choice A is faulty because an adverb such as twice cannot function as an object of the preposition by(用词). BY 后面要接名词 by 10 percent
B. , 倍數辭句型的用法敘述: .. times the/my N ... 結構︰…倍數詞+the(或所有格)+名詞說明︰此句型意為“是…的幾倍”。<倍數詞>與<名詞>之間一定有 the 或<所有格>。有時可改為“<倍數詞>+as+<形容詞>”。三倍以上的“倍”,通常用“times”。而“more than+<倍數詞>+the(或<所有格>)+<名詞>”譯為“是…的幾倍還不止”。 It was over twice the distance of the earth from the sun. 那是地球到太陽的距離的兩倍多。
C. two times 表示两次; double 表示两倍。B增长了超过两次 distorts the sentence's meaning, stating that the number of engineering degrees conferred increased on more than two distinct occasions.(歧义) 增长了两次!!! |
