Passage Two
A deadly infectious outbreak swept through a small city in Zaire， Africa last spring， killing more than one hundred people. The killer was a rare virus that caused most victims to bleed to death. As scientists rushed to control the outbreak, people in the U.S. wondered “Could it attack here?”“We are foolish if we think it couldn’t come to our country.” say doctors. The virus can be highly infectious. If you come in contact with a victim’s blood or other body fluids， you can get sick,too. All it takes is one infected person to start such a disease. That’s what scientists believe happened in Zaire. The healthcare workers who treated the first victims there soon fell ill too. The problem was they had no protective equipment to prevent themselves from being infected. International rescue worker
s brought equipment to Zaire soon after the outbreak occurred. Now the disease appears to be under control. One big mystery is that no one knows where the virus comes from or where it will strike next. some scientists say that the virus lies inactive in the cells of some kind of plant， insect or other animals. Then it somehow finds a way to infect humans. Scientists are now headed into the jungles of Africa to find out where the virus lives. Once they find the virus， they also hope to find ways to come at it.

16. What happened to most of the victims striker with this disease?
17. Why are the scientists going to the African jungles?
Passage Three
A team of scientists recently began a project to measure the effects of loud noises on sea animals. If the sounds don’t harm the animals， then the researchers can go ahead with a plan to transmit sound waves through the Pacific Ocean to take earth’s temperature. Sound travels faster through warm water than cold water. By
analyzing the speed of sound through the ocean over time， the scientists will be able to determine if our planet is warming up. The experiment was nearly cancelled more than a year ago because environmental groups fear that the sound will confuse or harm the seaanimals. So， scientists are conducting tests on the animals first. The researchers lowered a loud speaker that emits low frequency sound about l000 meters beneath the ocean. Scientists at the site transmit sound waves into the ocean. Radio transmitters attached to some of the seaanimals help the researches keep track of the animals’ movements. If seaanimals are distressed by the sounds， they would swim away from the speakers. So far， there aren’t any signs that the animals are being harmed. Researchers at the site noticed that large numbers of seaanimals swim near the speaker whether it was turned on or off， but it is still too soon to know for sure， the scientists admit. The test will continue through September. “If all goes well，”they say， we can begin measuring temperature changes on our planet.
18. What is&n
bsp;the purpose of analyzing the speed of sound through the Pacific Ocean?
19. What was the reaction of the seaanimals to the sound tests?
20. For what purpose were radio transmitters used?
