as early as早在---时

例句 radio broadcasting started as early as 1920

我这样说对不对He learned English as early as three years ago

你的句子是对的,这里给你补充一点点as early as 的用法和涵义。

1. 早在

as early as早在……...Colour printing was also invented by the Chinese as early as the 10th century .

2. 早……的时候

at the age of… 在……岁的时候...as early as 早……的时候...as soon as 一……就……

3. 表强调

as early as （表强调） I came here as early as 8 o'clock.

4. 早在……时候

as deep as(深达)，as early as (早在……时候)等。

希望能帮到你。

谢谢

又学到两个词组

at the age of at my age of 8 i m very thin.

as deep asthe lake is as deep as one hundred meter

as eary as 后面应该是一个时间点吧 整句是不是应该用过去时呢?

learning: as early as.
