1.The earliest people stored fire by keeping slow burning logs alight.
为什么BY后边的动词要加ING呢?是不是只要是BY后的动词都要加?
2.A bottle filled with sulphuric acid into which splints treated with chemicals were dipped.
这句话是怎么翻译呢?into which怎么翻译呢?
3.Costing a shilling a box,Congreves were splints coated with sulphur and tipped with potassium chlorate.
为什么句子的第1个单词用大写呢?是不是非谓语动词做主语,所以要这样用呢?

1.因为BY是介词，后面跟的动词都要用ing形式，这是固定的。
这里的by是通过（某方式、方法）的意思。
2.翻译：一块涂了化学药品的夹板被泡进一瓶装有硫酸的瓶子里。
这句话可以转换成这样：
Splints treated with chemicals were dipped into a bottle filled with sulphuric acid .
其中，into which 是dip的补充说明，即dip into a bottle.
which是非限定性定语丛句的标志，用于修饰先行词 a bottle.
3.所有句子的开头第一个字母都要用大写，不管开头的是名词还是动词还是动词ing形式，不然就不符合习惯，就是错的。
by doing sth 是固定句型
