Question

A.that used to be                           B.it is used to

C.it was used to                            D.it used to be

 

Answer 1

【答案】

 答案:D

解析:(than)it used to be是比较状语从句，it指上文中的life，used to be表示“过去是”。根据所提供的情景“life in the twenty-first century is much easier than”可判断出表示“以我看来，21世纪的生活比过去容易”。be used to后接动词+ing形式作宾语，表示“习惯于”，其主语一般是表示“人”的名词或代词。
