定语从句
在复合句中，修饰某一名词或代词，或修饰整个主句的从句叫做定语从句。它的作用相当于形容词。被定语从句修饰的名词或代词叫做先行词，引导定语从句的词叫做关系词，有关系代词wh，whm，whse，which，that，as和关系副词when，where，why。关系词既联系定语从句和它的先行词，同时又充当定语从句中的一个成分(主语、宾语、介词宾语、定语、状语或表语)。

（二）单元写作任务——如何写一篇新闻报道
新闻报道的特点：
1．主题突出。通常有比较固定的写作格式，如文首通常有报道的地点或时间，第一句话常常是文章的导语，是对整篇文章的高度概括。通过这句话我们可以了解文章的大致内容和主题。
2．标题醒目。好的标题能使读者在最短的时间内了解新闻的主要内容，引起阅读兴趣。
3．正文简洁生动。避免使用被动语态，抓住一些显著的细节进行深入描写，语法要正确，准确选取动词及时态等。
4．格式通常采用经典的“倒金字塔”格式，由三个部分构成，即标题(title)、导语(lead­in)和正文(bdy)。
新闻报道的格式：
先把你要写的事情概括一下，越简单越好。
接着把你概括的事件拓展一下，也就是写what is this abut。然后写5w＋h，也就是what，wh，when，where，why还有hw。最后就是cnclusin。
常用表达：
be determined t/make up ne's mind t d...
make cntributins t...
I wuld like t express...
pick up ne's curage
N wrds are strng enugh t express ur...
