英语高考难题2 As the number of visitors to the Forbidden City increases every year,a new solution___to reduce the pressure. A.carrying out B.carries out C.is carrying out D.is being carried out E.is being carried F.carried out
选择D 本句的前半句为原因状语从句,后半句为主句. 划分一下主句的句子成分就会发现, a new solution 主语 to reduce the pressure.不定式作目的状语. 那么主句中就缺少谓语动词. 由于是物作主语,所以谓语只能用被动语态.D/E是被动语态,但E本身存在错误. 希望你对您有帮助.
