  2021年上半年大学英语六级听力考点句(6)

  You see, I still have this pain in my back; this medicine the doctor gave me was supposed to make me feel better by now.

  点睛

  被动语态表示主动含义的用法在英语里很常见,但却与我们中国人的思维习惯相去甚远,考生需多加练习。分号后句子的意思是“医生给我开的药现在应该可以使我感觉好些了(意为说话人的症状现在未见好转)”。

  考点归纳

  be supposed to的用法如下:

  当be supposed to的主语是sb.时,意为“应该;被期望”,可以用来表示劝告、建议、义务、责任等,相当于情态动词should。如:

  Teachers are supposed to treat all students alike. 老师应该对所有学生一视同仁。

  当be supposed to的主语是sth.时,意为“本应,本该”,用于表示“某事本应该发生而没有发生”。如:

  The train was supposed to arrive an hour ago. 火车本应在一小时之前到达。

  当be supposed to后接“have+过去分词”时,表示“本应该做某事而没做”。如:

  You are supposed to have handed in your homework by now. 到现在你应该已经把作业交上来了。

  be supposed to的否定结构为be not supposed to,常用于口语中,意为“不被许可;不应当”。如:

  She was not supposed to be angry about that. 她本不该为那件事而生气的。
