    Typing(打字) is one of the most important and basic work skills of the 21st century. Because mobile phones are now so popular, there is a new kind of typing-thumbing. Thumbing means people use one or more thumbs(拇指) to touch the keys.

    Most people can type between 20 and 35 words a minute. Some typists, however, can work very quickly, at more than 110 words a minute. And people's left hand usually does 56 percent of the typing.

    The most common international English keyboard is QWERTY. People name it after the first letters on the top left side of the keyboard. It is more than 140 years old. Other keyboards include QWERTZ (in Central Europe) and AZERTY (used by most French speakers in Europe). Countries with non-Roman alphabets(字母系统), such as, Arabia, Russia or Japan, have their own keyboards.

    People practise the sentence "The quick brown fox jumps over the lazy dog" to make their typing better. That's because it uses every letter of the English alphabet.

    Thumbing and typing can hurt you. RSI (repetitive strain injury) is the name of a medical condition you get if you type too much. However, most people do not understand what RSI is or how serious it can be. Anyone who uses a computer a lot is at risk and should know about RSI.
