    1) when was it invented, and when was it used?Saying about a seed drill is a sowing device.

    Inventing and using it is like as following: In early time planting all the seeds

    . made by farmer’s own hands. Around 1500 BC had the single-tube seed drills used ,

    . and Multi-tube iron seed drills were invented

    . by the Chinese in the 2nd century BC

    . which were an efficient food production system .The perfect way and very good for farmer’s using

    . about the seed drill invented by Jethro Tull in year 1700. 關於播種鑽頭是一個播種機器。

    發明和使用是一樣如下:

    在早期的播種 由農民自己播種子

    公元前1500年左右曾使用的單管播種機,

    . 和 在公元前2世紀,中國人使用多管鐵播種機,

    這是一個高效的食品生產系統的發明。

    最完美的方式,非常適合農民使用有關播種機

    . 是由 Jethro Tull的在1700年發明的

    2 where was it invented? The earliest known version,

    . invented in Mesopotamia by 2000 BC, Seed drills would not come into widespread use

    in Europe until the mid-19th century.最早知悉是,到西元前 2000 年,

    . 發明了在美索不達米亞.直到 19 世紀中期播種機廣泛地使用在歐洲.

    3) what was it used for?

    In my idea , it was an efficient food production system . And it’s also to improve the farmer’s life我的想法,這是一個有效的食品生產體系。

    而且它也提高了農民的生活,

    4) was it successful? why?

    It’s really successful because such machine for planting seed

    . at a controlled depth and in specified amounts.The seed drill allows farmers to sow seeds in well-spaced rows

    . at specific depths at a specific seed rate;

    . each tube creates a hole of a specific depth,

    . drops in a seed, and covers it真的成功,因為這種機器的種子播種在受控制的深度

    . 和指定量.

    該播種機易於農民播種, 排特良好的間距, 特定深度,

    . 特定結實率,每管會創建一個特定深度的孔,

    . 滴在種子,並覆蓋它.

    5) how important was it? how did it change the world?

    You know what ! JethroTull's seed drill would sow seed in uniform rows repeatedly

    . instead of the wasteful method of scattering seeds by hand .By the way , Jethro Tull is an Englishagricultural pioneer too.你知道嗎 ! Jethro Tull 的播種機替代用手將播下種子不會浪費之方法

    該機反復可播下種子.

    順便提一下,Jethro Tull的是英果國農業的先驅者呢。
