In the age of the smart phone, there seems no reason to ask questions about: the weather forecast, a business’s phone number or directions, which can all be    1     (easy) found on Google, but very often people actually ask these things by    2     (make) a call. Your answer may be replied to with a thank-you e-mail.

This isn’t the first time that great changes     3     (take) place in our manners due to technology. In    4    late 1870s, when the telephone     5     (invent), people didn’t know how     6     (greet) a caller. Often there is just     7     (silent). Alexander Graham Bell, the inventor, suggested that people     8     (say) “Ahoy”, but finally “Hello” went out, the greeting used in everyday face-to-face communications now.

Try to be respectful no matter     9    you communicate with. Just keep    10    mind that politeness never goes out of fashion.
