雅思写作模仿造句如何表达“某事物在某个时间内消失”

## 句子结构 ## A is likely to vanish within B. A 可能在 B 时间内消失。 注：B指的是某段时间 ## 结构来源 ## Half the world's 6,800 languages are likely to vanish within two generations — that's one language lost every ten years. 全世界6800多种语言中有一半很可能在两代人的时间内消失——这意味着每十年就会有一种语言消失。 ## 结构解析 ## 句子主干是主系表结构，表语 likely to vanish within B 。be to do sth 可能将要怎么样，表示对A的一种推测。Vanish 意为消失，相当于 disappear，be gone，within B 介词短语作为时间状语。 ## 模仿造句 很多人曾误以为白鳍豚不可能在几年的时间内灭绝。 Many people harbored the misconception that Chinese river dolphins were not likely to vanish within several years. ## 知识点梳理 ## ### 单词 vanish 小时 harbor 庇护，藏匿 misconception 误解，错误概念 ### 定语从句 在主从复合句中，对名词（或者整个句子）限定修饰，起定语作用的句子，就是定语从句。 ① They rushed over to help the man <u>whose car had broken down</u>. ② The school <u>that he once studied in</u> is very famous.
