The first mobile phone was <u>designed</u> in 1973 by a man named Martin Cooper,who was a n <u>invented</u> with electronic devices.He <u>built</u> the first mobile phone to look like a phone,but it didn't look like the ones we use today.It was a very large,heavy phone,and the <u>battery</u> only for 20 minutes.However,Cooper said that wasn't a problem because you couldn't hold the phone up for that long.Since then people have <u>found</u> out ways to make mobile phones very small .They can also be used for other things,like planning your day,or as a <u>calculator</u> to do simple math problems.They can be used in the countryside too,thanks to tall <u>towers</u> that mobile phone companies have <u>cities</u>.Mobile phones have become so important that most of us couldn't live without them.
