1. 英语作文,迄今为止最好的发明
，下面就听我慢慢道来。
No。1
品名：绿化枪发明者：杨启源
作用：使绿化更为简单、便捷。
危害：迄今为止还未发现。
结构描述：此枪非常像美国的柯尔特左轮手枪，弹轮容量为6发，拆卸弹轮十分方便，子弹由三部分组成，一是弹头，用来装种子的；二是炸药，用来散发种子的；三是红外线接收仪（至于什么用处，以后会讲）。子弹出膛后会自动打开红外线接收仪，探测来自预先设在地面上的红外仪发射的红外信号，当探测到时，立刻校正航向，直奔红外仪，在红外仪上空爆出种子，这些经过特殊处理的种子一旦落到土里，地面就会有仪器自动喷出一道道“水”柱撒在表面，不但可促使种子生长，还赋予了种子抗病能力，并且，水柱喷洒时间可人工设置，节省了很多人力物力。
备注：此枪由于子弹太长太重（100毫米，250克左右），并且响声太大，所以，劝告力气小者及心脏不好者，最好不要接近此枪，否则，后果自负！

9. 英语作文你认为最有用的发明
The telephone is an instrument that converts voice and sound signals into electrical impulses for transmission by wire to a different location, where another telephone receives the electrical impulses and turns them back into recognizable sounds. In 1875, Alexander Graham Bell built the first telephone that transmitted electrically the human voice.
When Bell began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years. Although a highly successful system, the telegraph, with its dot-and-dash Morse code, was basically limited to receiving and sending one message at a time. Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of a multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. His "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.
