下面这道题为什么选D而不能选A25.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
be used to do 表示被用来做
used to do 表示过去常常
that 常用来指代不可数名词,在这种地方一般用it
根据题意,它想表达的是：21世纪的生活比过去的生活更简单.
............................................................................................................
used to 过去常常
be used to 习惯于
关键还是代词的问题 ，原句剪掉为 life () is much easier than - used to be.
that / it 前面多为关系代词， 后面一个为指示代词。觉着后面一个更贴切！
