题目内容
Trinidad and Tobago is a single country composed of two islands.. Trinidad, with the majority of the country's 900,000 inhabitants, is a rectangle of roughly fifty by forty miles. Tobago, nineteen miles to the north, is smaller and has a population of about 35,000.
Situated at the end of the long chain of Windward and Leeward Islands, Trinidad is at one point only seven miles off the coast of Venezuela. Its geology, flora, and fauna are similar to those of the South American mainland. Like Venezuela, the backbone of Trinidad and Tobago's economy is petroleum and its first colonists were Spaniards.
Three mountain ranges, with summits of up to 3,000 feet, cross Trinidad from east to west, while Tobago is a relatively flat coral island, rimmed with fine beaches. The broad plains between Trinidad's mountain ranges are dominated by vast fields of sugar cane that present a symmetrical green pattern when seen from the air. A closer inspection reveals the coconut plantations along the coast and the profusion of brilliant red and yellow flowers of various species that are found all over the island. Houses on both islands tend to be light-colored, with an open style. of architecture, in many cases with open space under the entire dwelling. Port-of-Spain, the capital, is a bustling modern city where the pulse of the people reflects Britist, Spanish, and East Indian influences.
The title below that best expresses the main idea of this passage is ______.

听力原文： No one knows exactly why we sleep. But scientists have learned a lot about how we sleep, From sleep experiments, scientists have learned that there are four different stages of sleep.
When you first fall asleep, your heart starts to beat more slowly and your breathing slows down. If something wakes you, you might not think that you had been asleep. Some people call this kind of sleep dozing. Scientists call it Stage One sleep. Next, if you are not awakened, you drift into a deeper sleep. Your pulse and breathing become even slower than they were during Stage One sleep. But you can still be awakened quite easily. If you take a cat nap, you probably will not get any further than this stage of sleep, which is called Stage Two.
If you sleep longer than about twenty minutes, you go into the third stage of sleep. Your body is very relaxed. It would take a loud noise to wake you up.
You have probably heard of people who walk in their sleep. No one knows what makes people sleepwalk. But a person can sleepwalk only during Stage Four. This is the deepest kind of sleep. If someone wakes you up during stage four, you might feel very confused. It might take you a few minutes to get used to being awake.
