句法分析句中what cncerned him mst为主语从句,what在从句中做主语;that引导表语从句,that仅为引导词,在从句中不做成分,也没有任何意义。that和what都可以引导名词性从句。that引导名词性从句只起连接作用,在从句中不做任何成分,无意义,在宾语从句中通常省略,但在主语从句、表语从句和同位语从句中均不能省略;what除引导从句外,what本身在从句中可做主语、宾语或表语,意为“……的(东西)”,在含义上相当于“名词+that”。

句法分析这个句子的真正主语是从句that abut 60 year。因为真正的主语太长,为了避免句子头重脚轻,所以用形式主语it,构成“It+be+过去分词+that”句式。英语中还有许多类似的结构,如:It is said/believed/reprted that...;有时,该句型可以转换为“Sb/Sth+be said/believed/reprted + t d”或“Peple ”的形式。

语境领悟(1)Given his age,he is very strng and healthy.考虑到他的年龄,他已经非常强健了。(2)Given that the students need mre exercise,the head teacher has decided t add mre PE classes.考虑到学生们需要更多的锻炼,校长已决定增加更多体育课。
