帮我分析一下这几个句子的成分

成分分析最简单的不过主语，谓语，宾语/表语/状语，及在其基础上的补语，从句

1.主语:so many thousands of terrified people
谓语：died
状语（从句）：every time there was an outbreak

2.形式主语：it
谓语：seemed（系动词）
表语从句：the water was blame

3.（目的状语）状语：To prevent this from happening again
主语：jogn snow
谓语：suggested
宾语从句：thar the source of all water supplies be examined and new methods of dealing with polluted water be found

1. so many thousands of terrified people(主语） died （谓语）every time（连词） there was an outbreak （从句）

2 It seemed the water was blame （形式主语从句，the water was blame才是真正的主语）

3 To prevent this from happening again（目的状语从句）, jogn snow suggested （谓语）that the source of all water supplies（suggest+taht+（should）+do固定语法） be examined and new methods of dealing with polluted water（ be found定语修饰water）.

根据感觉+经验=v=、

其实是语法的组成。有时跟汉语差不多。

看语法书吧=v=
