"Blind as a bat" is often heard. Yet they have no trouble flying in the darkest nights and finding their way around. How can bats fly and see at night? They fly by radar . The bat's radar system works the same way as the one that ships and planes use. When a bat flies through the air, it makes sounds that people can't hear. If the sounds hit things, they will come back. The bat's ears can receive the messages. In this way it can know where the things are. Bats go out to look for food at night. In the daytime they stay in some dark places. Some people think bats are bad animals. In fact, they are useful animals. Question: The bat "sees" things with its _ .

Usually, these stories do not have much truth to them. One of the biggest fish stories in history was about a whale. In 1891, a ship hunting for whales in the South Atlantic Ocean found a very large whale. While the hunters were trying to kill the whale, it sank two small boats. One man drowned, and another man, James Bartley, was lost in the ocean. However, after the hunters finally killed the whale, they cut open the whale's stomach and found Mr Bartley inside. He was not dead! Several weeks later, Mr Bartley seemed to have gotten over his terrible experience. The only thing he could remember was that while he was inside the whale, it was very hot. The liquid from the whale's stomach had turned all of his skin snow white. Mr Bartley had to live with the effect from the whale for the rest of his life. Today, many people have heard about the strange experience of Mr Bartley and do not buy it. Not one real fact has been found to prove that the events ever took place described by the sailors. No scientist or newspaper reporter was ever able to talk to Mr Bartley, and all of the stories told in magazines about Mr Bartley's experience were explained by other sailors on the boat. Mr Bartley was probably not even a real person at all. In 1928, after the captain of the whaling ship had died, one man asked the captain's wife about Mr Bartley's story. The wife said that no man who had sailed on her husband's ship was ever swallowed by a whale. However, this has not stopped James Bartley's story from being repeated, and many people today still believe that it is true. Question: Who may have talked to Mr Bartley? Options: A: A scientist. B: The captain's wife. C: The sailors on the ship. D: A newspaper reporter.

Nearly all people think it's impossible, but there are some more earthquakes in recent years. Animals can predict the weather or other natural events. It may sound strange, but farmers living in the countryside think so. For hundreds of years , they have observed animals. "Animals ' behavior can be connected to future weather conditions or events." They say. For example, if cows lie down, a rainstorm is coming. There are many traditional stories connecting animals and natural events. Many people think that these stories don't have scientific evidence( ) at all. Scientists, however, are beginning to take another look at some of these ideas. A Japanese earthquake researcher named Kiyoshi Shimamura noticed an increase in dog bites a short time before earthquake hit. Then he did research on twelve public health centers in Kobe, Japan. These health centers treated people after the 1995 earthquake . He got some interesting information about the month before the big earthquake: treatment for animals' bites had increased . In fact, aggressive behavior in dogs, such as biting and barking loudly , jumped 60 percent. There are also other changes in animals' behavior before the earthquake. For example, fish began swimming together in large groups , but only in the middle of the water and not near the edges. Birds flew away from their nests for many days, leaving their eggs unprotected . These animals' behavior suggests that animals may be able to predict natural events better than people. Question: What do dogs begin to do just before an earthquake? Options: A: They leave their homes. B: They hurt people. C: They lie down in grass. D: They stay together in large groups.
