1.C
首先根据句义,Lucy是不知道该先解决哪个问题,而非怎么解决问题.
所以排除A 、D.这两项表示怎样解决.
B,When 询问时间与first矛盾,使句子不通.
2.D
the more difficulty we have这一分句中,we have 是difficulty的后置定语,是用来修饰difficulty的,所以与填空无关.排除A
根据词组 have difficulty doing
得知选D--- Do you know _____________? --- Sorry, I have no idea. I’ll search the Internet to find it out. A. where will the next Expo be held B. when will the next Expo startC. what will the next Expo be held for D. how many countries will take part in the next Expo那这道题呢??答得好我回家加分的Do you know 后面是一个宾语从句,根据宾语从句的语序will 该在the next EXPO 后面所以选D
