选择题
This is an illness that may result in total blindness if .
A.being left untreated
B.left untreated
C.not left treating
D.not having left untreated
答案
答案:B
要做好省略结构的题目,考生必须明白省略了哪些成分,学会将句子整合。如本题从句可补全为:if it is left untreated。另外,本题的另一个难点是:学生对untreated的用法搞不明白。老师可将此结构先用主动形表达,即People left the illness untreated.此处untreated作宾语补足语,与illness构成被动关系,转换成被动句为:The illness is left untreated.本句话语意为:如果不治疗,这病可能会造成双目失明。
