In old times，man considered lightning to be one of the great mysteries（神秘事物）of nature．In fact a single flash of lightning 1.6 kilometers long has enough electricity to light one million lamps．
The American scientist，Benjamin Franklin，was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above．It happened in 1752．In the same year，he also built the first lightning rod（避雷针）to protect buildings from being struck by lightnings．
Modern science has discovered that lightning is very strong and powerful．A lightning between a cloud and the earth may be as long as 13 kilometers，and travels at a speed of 30 million meters per second．Scientists have the opinion that there are about 2000 million flashes of lightning per year．In the United States alone，it kills almost one person per day．

In Canada and the United States, people enjoy entertaining(请客)at home. They often invite friends over for a meal, a party, or just for coffee and conversation.
Here are the kinds of things people say when they invite someone to their home:
" Would you like to come over for dinner on Saturday night? "
" Hey, we're having a party on Friday. Can you come'? "
To reply to an invitation, either say thank you and accept(接受), or say you're sorry and give an excuse(借口):
" Thanks, I'd love to. What time would you like me to come?" or " Oh, sorry. I've tickets for a movie." Sometimes, however, people use expressions(措辞)that sound like invitations, but which are not real invitations(邀请). For example:
" Please come over for a drink sometime? "
" Why not get together for a party sometime? "
"Why don't you come over and see us sometime soon?"
They are really just polite ways of ending a conversation. They are not real invitations because they don't tell time or date. They just show that the person is trying to be friendly. To reply to expressions like these, people just say: "Sure, that would be nice!" or "OK. Yes, thanks."
