Making the news
谓语[predicate verb]是对主语动作或状态的陈述或说明,指出“做什么”、“是什么”或“怎么样”. 谓语动词的位置一般在主语之后。
依据其在句中繁简程度可把谓语分为简单谓语和复合谓语两类。凡由一个动词(或动词词组)构成的谓语都是简单谓语。
复合谓语 可分为两种情况: 第一种是由情态动词,助动词+不带to的动词不定式构成的谓语: You’d better catch a bus. 你最好乘坐公交车。 We have just had lunch. 第二种是由连系动词+表语构成的复合谓语 He looked worried. 他看起来很忧愁.

Step1:呈现& 发现
Inversion 倒装句
一、含义
在英语中,主语和谓语的语序通常是主语在前、谓语在后。但有时为了强调句子的某一部分或其他原因,谓语需要全部或部分移到主语的前面,这种语序叫倒装。
Step2:理解& 归纳
二、分类
倒装有两种:完全倒装和部分倒装。在倒装语序中,若整个谓语都在主语之前,称之为完全倒装。若谓语的一部分(通常是助动词、情态动词或 be 动词)位于主语之前,则称之为部分倒装。

倒装的分类
1. 全部倒装: 主语与谓语动词倒装
结构:谓语动词+ 主语

= The rain fell down.
2. 部分倒装:主语与助动词/情态动词/系动词倒装
结构:助动词/情态动词+ 主语+谓语动词
Never have I heard such a thing.
= I have never heard such a thing.
主语位于谓语are there之后
原句自然顺序是:
