主动 vs 被动
主动句: The king (主语) / offered (谓语) / him (宾语) a pension (宾语).
被动句: 主动变被动–> 宾语 + be + done (谓语) + by + 主语.
He was offered a pension by the king.
A pension was offered to/for(不强调动作) him by the king.
阅读例句: The metal industry was established at Riverside Village by sb.. (题目为被动句，答案找原文主语)
原文: At that time, sb. first build an iron forge just behind the village.
听力例句：The sth. will be explained to you before you use the equipment.
听力原文: The trainer will then take you through the safety rules before you using the equipment.
there be
句式：there be + n. / there be + 数词 + n.
常见错误：there be + 谓语(这样会组成双谓语，语法错误)
例句: Several reasons contribute to the result. (正常句式: 有几个原因导致了这个结果)
There are several reasons contribute to the result. (语法错误,双谓语)
There are several reasons contributing to the result. (正确，将contribute变为非谓语动词)
疑问句->陈述句
特殊疑问句变陈述句三步走:
1）去掉疑问词（when/where/why/how/what/who）
2）还原陈述语气–>主谓
3）将答案补充在相应位置（通常是句尾）
