结合一个发明实例,谈谈你对发明的看法的英语作文

The computer is a useful machine. It is one of the most important inventions. The oldest kind of computer is the abacus, used in China many centuries ago, but the first large and modern computer was invented in 1946. The computer could work out maths problems quite fast.

Now the computers are getting smaller and smaller, and computing faster and faster. Many scientists agree that computers can now do many things, but they cannot do everything. Who knows what the computers tomorrow will be like? Will computers bring good things or bad things to people? The scientists today have to decide how to use the computers tomorrow.
电脑是一个有用的机器。这是最重要的发明之一。最古老的计算机是算盘,几百年前就在中国使用,但第一大和现代电脑是1946年发明的。电脑可以很快解决数学问题。
现在,电脑变得越来越小,而计算速度却越来越快。现在许多科学家认为电脑可以做许多事情,但是他们不能做所有的事。谁知道明天的电脑会是什么样子呢?电脑会带来好事情还是坏事情的人吗?科学家们今天明天必须决定如何使用电脑。

the most important invention to me
　　There are many remarkable inventions in the world such as computers, televisions, radios, modern vehicles and so on. Each of them is playing an essential role in our lives. However, for me, the most important one is mobile phone.
　　The first mobile phone in the world was invented in late 1970s. With the rapid development of electronic equipment and radio technology, mobile phone is getting smaller and smaller and more and more multifunctional. Nowadays, people are able to use a cell phone to make a call, search information or even shop online. How awesome it is!
　　As for me, I usually use my cell phone to contact my friends, relatives, colleagues as well as clients. Modern technology makes it possible for us to communicate conveniently with those away from us. It is quite unthinkable for me to live at a time when cell phone has not been invented.
