Most people, at one time or another, have been on the receiving end of a random act of kindness — that moment when a complete stranger stops 【小题1】 (offer) aid, generosity or sympathy.

The city of Naples has long had a tradition 【小题4】 (call) “caffè sospeso”. When buying coffee, a person who has recently been 【小题5】 (luck) would purchase two cups but only drink one, leaving the second one anonymously, out of the goodness of their heart, for a poor person to claim for free. This tradition is now more common worldwide.

However, in some cases, these little acts can be a matter of life and death. Take, for example, the unnamed commuter, who in June 2018 【小题6】 (fall) off a station platform onto an electric railway track in Toronto, Canada. A quick-thinking bystander selflessly leapt down to pull him to 【小题7】 (safe).

Or Jonny Benjamin, who in London in 2008 【小题8】 (persuade) not to commit suicide by a passer-by. He had been considering 【小题9】 (jump) from a bridge. He later found the Good Samaritan and thanked him 【小题10】 his kindness. He may one day find a way to pay him back in kind — though that’s not the point.

So, why do it? Often, the acts aren’t reciprocated （回报）. The people never meet again. However, acts like these can “give our lives new purpose, show us other viewpoints on our own problems and even make us feel very happy and excited.”

Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes（蚊子）in the town, 【小题5】（suggest）that he'd better not 【小题6】there. Mark Twain shook his hand and said, "It doesn't matter. The mosquitoes are no relatives of mine. I don't think they will come to visit me."

After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about 【小题7】（have）a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. "I'm very sorry, Mr Mark Twain. There are too many mosquitoes in our town," one of them said to him.

Mark Twain, 【小题8】, made a joke, saying to the waiter, "The mosquitoes are very clever. They know my room number. They didn't come into the wrong room." What he said made all the people in the room laugh 【小题9】（heart）.

But that night Mark Twain slept well. Why? That was because all the waiters in the hotel 【小题10】（drive）the mosquitoes away for him during the whole night.

Anne was still upset and 【小题10】 (cry)．
