what does the sign exit mean?it means( )A you can open the door if you pull B you can go in through
that door C you can open the door if you push D you may go out from that door (解析） they( )to help the farrners with the harvest Aasked B are asking C are to ask D were asked(解析

答案

1.exit n.way out ,出口.——从大词典查到
只有 “ D.you may go out from that door” 的意思与 “出口” 相符.
2.他们被请求去帮助农民收割.
只有挑选 D were asked 句子意思才通顺.
选 A,B,——他们请求…….请求谁去帮助农民?没有说,句子不通.
C,are to ask,他们去请求…….同样没有说出请求谁去帮助农民,句子的意思也是莫名其妙.
