Intensive research is yielding important insight into E1 Nino, a periodic warming of tropical waters in the Pacific that can trigger devastating drought and flooding. Scientists are finding that the phenomenon exists in reverse; some call it La Nina. Typically E1 Nino, like the calamitous 1982 - 1983 event that brought misery to places as far apart as Ecuador, Australia, and southern Africa (National Geographic, February 1984), announces itself with strong westerly winds along the Equator, accompanied by a warm current that usually arrives off western South America around Christmas, which led to its name, Spanish for "the Child". Ocean fisheries suddenly collapse, and coastal deserts reel under torrential rains that sweep away villages.
Scientists now believe that between E1 Ninos there often are La Ninas: one-or-two-year periods when the surface water of the equatorial Pacific becomes cooler. Experts detected the onset of La Nina in the spring of 1988, leading some to link it to last summers' drought in the United States, flooding in Bangladesh, and the abnormal cold winter in Alaska and western Canada.
The early detection of E1 Ninos and La Ninas is an invaluable tool for long-range weather forecasting.
The best title for the passage would be ______.

--Never thought to see you here.—______
听力原文： I have been an airline stewardess for six years. I'm twenty-six years old and recently got married. The majority of the airline stewardesses are from small towns. I myself am from Nebraska. It's supposed to be one of the nicest professions for a woman -- if she can't be a model or in the movies. You can fly around the world, meeting all those people. It is pretty nice doing so.
I have five older sisters and they were all married before they were twenty. The minute they got out of high school, they would end up getting married, that was the thing everybody did. It was to get married. They were so happy that one of the girls could go out and see the world and spend some time being single. I didn't get married until I was almost twenty-five. My mother especially thought it was great that I had the chance to travel around the world.
How old was the narrator when he became a stewardess(空姐)？
听力原文：M: Excuse me.
W: Yes ？
M: You can' t park here.
W: But it' s only for a few minutes. I' m waiting for a friend.
M: This is a taxi park. You can park in the car park round the corner over there.
What is the relationship between the man and the woman？
