系统解析:范文点评:
1.针对自由迁徙给出相对立的两种观点,有人认为利大于弊,有人认为弊大于利。
2.自然过渡,引出个人观点,即自由迁徙利大于弊。
3.分三个层次展开论述,论证自己的观点。
4.末句既是结论,又重申了主题。
句法点评:
1. Some hold the view that free movement accelerates the economy, while others believe that free movement causes various problems on employment, education, welfare, imbalance of talent distribution and so on.
that引导的是同位语从句解释说明前面观点的内容。可以跟同位语从句的名词通常有news, idea,fact,promise,question,doubt,thought,hope,message,suggestion,word (消息),possibility等。如:I heard the news that our team had won.我听到了我们队获胜的消息。
2. To sum up, free movement is an irreversible trend that quickens the speed of social progress.
that引导的是定语从句,修饰先行词trend。that引导的不是同位语从句,区分定语从句和同位语从句的其中一个方面是:看引导词的作用。 引导同位语从句的that是连词,在从句中不充当任何成分;而引导定语从句的that为关系代词,在从句中充当一定的句子成分。在此句中,that为关系代词,在从句中充当主语。
