题目内容
1.So far,there has been no scientific consensus about _________ includes the risk of eating GM food.( )A. | what is it that | B. | what it is that | C. | it is what | D. | what is it |
分析 到目前为止,食用转基因食品究竟有哪些风险,科学界还没有达成一致看法.
解答 答案:B 本题考查的是强调句型在宾语从句中的使用.该句结构比较复杂:what引导的从句充当介词about的宾语;it is…that…强调句型对从句的主语what进行强调.分解一下就是:what includes the risk of eating GM food和it is what that includes the risk of eating GM food,而what在句子是连词,要放到从句前面.故选B.
点评 强调句型是英语中一个常用的结构,使用方便,容易掌握.解题时,要注意强调句型的特点:强调句型只调整了被强调部分的位置,不影响原来句子的结构成分.这是判断一个句子是否是强调句型的方法,要掌握和学会使用.本题是一种比较复杂的使用,要学会分析.
