这个题目：We rely on the news for knowledge of the world, but we are unsure how far to trust journalists, what do you think? And discuss what are the important qualities journalists should have?

学生在主体部分某段第一句写了下面这句话：
  Protests and rebellions could be totally wiped away on the paper to make an illusion of peace and harmony—stains are not allowed to be exposed in order to ensure the power and interest of authorities.

修改后如下：
  Serving in the state-owned news agencies, many journalists would wipe protests from their coverages or distort the facts, so as to ensure the power and interests of authorities.

  英文中的破折号dash（——）：常用在一个解释性的插入语前面和后面，相当于括号；也常用在一个解释性的分句或句子前面。但原文破折号后面的信息还不如其意图解释的内容来得通俗易懂，不如删去。

  被动语态在英文中出现要符合几大要求，其中有：动作执行者不明或不重要。但原句中未出现的执行者journalists明显是题干的核心讨论对象，不仅不建议删除，还需要自然过渡出和authorities的关系。

  改动之后，讨论对象journalists和观点中authorities之间的关系可以通过一个前置的现在分词短语serving in the state-owned news agencies体现，此处就是利用前置的分词短语作原因状语；

保留journalists wipe protests from coverages的目的，以so as to不定式作目的状语引出。

★ 小总结 ★
非谓语动词（分词及不定式）也是有效展现原因、目的等状语的手法。更多雅思真题解析资料，请关注朗思教育官方平台！
