Question

In my opinion,life in the twenty-first century is much easier than _______.

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

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

Answer 1

D

解析:

(than)it used to be是比較狀語從句，it指上文中的life，used to be表示“過去是”。根據(jù)所提供的情景“l(fā)ife in the twenty-first century is much easier than”可判斷出表示“以我看來，21世紀(jì)的生活比過去容易”。be used to后接動詞+ing形式作賓語，表示“習(xí)慣于”，其主語一般是表示“人”的名詞或代詞。
