There is one extra sentence which you do not need to use. Bacteria are extremely small living things. While we measure our own sizes in inches or centimeters, {{U}}(72) {{/U}} . One micron is a thousandth of a millimeter; a pinhead is about a millimeter across. Red-shaped bacteria are usually from two to four microns long, while rounded ones are generally one microns in diameter. Thus, if you enlarged a rounded bacterium a thousand times, {{U}}(73) {{/U}} . An adult human magnified by the same amount would be over a mile (1.6 kilometers) tall. Even with an ordinary microscope, you must look closely to see bacteria. {{U}}(74) {{/U}} , one finds that bacteria are barely visible as tiny rods or dots.

Bacteria under the microscope, even those with no flagella, often bounce about in the water. This is because {{U}}(78) {{/U}} . Molecules move so rapidly that within a tenth of a second the molecules around a bacterium have all been replaced by new ones; even bacteria without flagella are thus constantly exposed to a changing environment. Sentence: A. Using a magnification of 100 times. B. It would be just about the size of a pinhead. C. Water is as thick as molasses is to us. D. The bacteria content different liquids. E.

单选题{{B}}Section B{{/B}} Directions: In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in a maximum of 10 words. Questions 61-65 are based on the following passage. Going to the beach is many American's favorite activity. In the area near New York City, nine million people used to go to the beach every summer. They went swimming in the ocean without giving a thought to what was underwater. But those days are long gone. In the summer of 1988, the government was forced to shut down beaches all over America. Many of the beaches had to be closed because garbage from hospitals was found in the water. The garbage including glass bottles with samples of blood, and people were afraid they might get AIDS from the blood. Where the medical garbage came from is anybody's guess. At some beaches, sewage was found in the water. Americans were shocked by this state of affairs. They had long taken for granted that oceans were big enough to stay clean, even if garbage and sewage were dumped into them. People didn't think of the underwater garbage because it was out of sight. Some of the most polluted waters still look beautiful at first glance. San Francisco Bay is a good example of a beautiful bay that's full of chemicals. Scientists discovered pollution in some lakes and rivers when they found fish with rotting skin. In some parts of American, people are told not to eat too much fish because of pollution. Most American cities put their garbage in the ground. But New York and a few other cities put their garbage in the ocean. Boston Harbor's is so polluted that scientist say it won't recover until the next century at best. The city of Boston puts its sewage in the water. The government has ordered the city to build a sewage treatment plant. Cleaning up oceans won't be easy, but people can no longer ignore this challenge.
