2003年一月题
33题:Between 1871 (until) 1891 , the (population) of Toronto (more than ) tripled , increasing (from) 56000 to 181000.
“increasing”是否能改为非限定性定语从句,WHY?
34 题: In the nineteenth century , Montreal grew (into) an important (transportation) and industrial center , (aided) by its many natural resources and an (abundant ) of hydroelectric power.
“aided”能否改为非限定性定语从句,WHY?
还有Tere are many beautiful skyscrapers , which were built in 2004 ?这个句子中的which were能否去掉?为什么?
刘述语法笔记中定从省略中讲到,定从中,主语+BE可同时省,——这是一种什么情况,能否举例说明一下(我感觉同时省略后,好象就变成了过去式作后置定语,同时省的情况是不是局限于限定性定语从句,非限定性定语从句中能否省略)
