There is a new problem involved in the popularity of private cars road conditions need . A. that ...to be improved B. which...to be improved C. where ...improving D .when...improving [答案]A.考查同位语从句 [点拨]因为先行词在从句中不作任何成份.因此用关系词that.故B.C.D均不正确.对于第2个空格.need既可作实义动词.又可作情态动词.作实义动词时后跟动词不定式.即need to do sth..另外 road conditions与improve之间是被动关系.因此是need to be improved(need to be done=need doing).译文:私家车受欢迎所涉及到的新问题是道路状况需要改善 【查看更多】
