Deep inside a mountain near Sweetwater in East Tennessee is a body of water known as the Lost Sea. It is listed by the Guinness Book of World Records as the world’s largest underground lake. The Lost Sea is part of an extensive (covering a large area) and historic cave system called Graighead Caverns.
The caverns have been known and used since the days of the Cherokee Indian nation. The cave expands (becoming large in size) into a series of huge rooms opening on the side of the mountain. One mile from the entrance, in a room called“The Council Room”,many Indian artifacts(手工艺品)have been found.
For many years it had been considered that there was a large underground lake somewhere in a cave, but it was not discovered until 1905. That year, a thirteen-year-old boy named Ben Sands crawled into a small opening three hundred feet underground. He found himself in a large cave half filled with water.
Today, tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats. More than thirteen acres ( 英亩 ) of water have been mapped out so far and still no end of the lake has been found. Even though teams of divers have tried to explore the Lost Sea, the full extent (the size of a large area)of it is still unknown.

第1卷单元月考期中期末系列答案
Honey(蜂蜜)from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest(巢)and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper一a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax (蜂蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees’ nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or people as it leads them to the nest. When they
finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
