[单项选择]I’m in Paris, and a strangely quiet Paris it is. Nothing is going nowhere. If they’re not on strike here, they’re stuck in a traffic jam. It took me two hours to go two miles yesterday evening. And this morning many of the taxis, too, have joined in, leaving me with no alternative but to start walking. And it’ s bitterly cold!

People are once again talking to people; strangers are going out of their way to befriend strangers, allies for a week or two in their shared frustration. Parisian motorists, even, normally the most competitive of individualists, have been seen leaving notes in their parked cars saying where they are going and when they expect to leave in case anymore wants a lift.

[单项选择]One of the well-known of American writers is Samuel Clemens, whose pen name is Mark Twain. Born in 1835, Twain grew up in the Mississippi River town of Hannibal, Missouri. As did many other boys of his day, Twain dreamed of traveling on river boats and of someday becoming a riverboat pilot.
