重点解析
1
(教材P13)Believe it or not，there is no such thing as standard English.
信不信由你，(世界上)没有什么标准英语。
【要点提炼】
there is no such...(as...)是固定句式，表示“(世界上)没有(像……)这样的……”。句中“no such＋单数名词”意为“没有这样的……”，其中单数名词前不可再加冠词，相当于“not such a/an＋单数名词”；as在此为介词。
【归纳拓展】
such还可用于以下几种结构：
such
a(n)+adj.+单数可数名词
adj.+不可数名词
adj.+复数名词
+that
such…as…像…这样的… ,as引导定语从句
①It is such a beautiful park that everyone wants to visit it.
这是一个如此美丽的公园，每个人都想去参观。
(that引导结果状语从句)
②It is such a beautiful park as everyone wants to visit.
这是一个每个人都想去参观的美丽的公园。
(as引导定语从句)
【实例分析】
such与a/an连用时要放在a/an的前面；与all，no，some，any，few，little，many，much，several，one等词连用时，应位于它们的后面。
