语篇练习一、阅读理解阅读以下短文，从每题所给的A、B、C、D四个选项中选出最正确选项。AFever, coughing.most of us at one time or anotherhave had these symptoms. What causes them?In fact, many diseases are caused by viruses, includingsome deadly ones like AIDS, SA RS and COVID-19, alsoknown as the novel coronavirus pneumonia.What are viruses? How can viruses cause so muchtrouble? Viruses are very small particles which areabout one millionth of an inch long. Unlike human cells orbacteria, viruses aren't living organisms-they can'treproduce on their own. Instead, they invade the cells ofliving organisms to reproduce, spread and take over.Viruses can infect every living thing-from plants andanimal down to the smallest bacteria. For this reason, they a re always a potential danger to humans.Viruses lie around our environment all of the time,waiting for a host cell to come along. They can enter ourbodies by the nose, mouth, eyes or breaks in the skin. Onceinside, they try to find a host cell to infect. For example,HIV, which causes AIDS, attacks the T-cells of theimmune system.But the basic question is, where did viruses first comefrom? Until now, no clear explanation for their originexists. "Tracing the origins of viruses is difficult, "EdRybicki, a scientist at the university of Cape Town in SouthAfrica, told Scientific American, "because viruses don'tleave fossils and because of the tricks they use to makecopies of themselves within the cells they've invaded."However, there are three main theories to explain theorigin of viruses. First, viruses started as independentorganisms, and then became parasites（寄生虫）.Second,viruses evolved from pieces of DNA（脱氧核糖核酸）orRNA（核 糖核酸）that u escaped'" from larger organisms.Third, viruses co-evolved with their host cells, whichmeans they existed alongside these cells.For the time being, these are only theories.Thetechnology and evidence we have today cannot be used totest these theories and identify the most plausible（看似合理的）explanation. Continuing studies may provide us withclearer answers. Or future studies may find that the answeris even more mysterious than it now appears.1. What can we learn about viruses from the text?A. Viruses have nothing to do with the common cold.B. Viruses are really small living organisms.C. Viruses can't reproduce unless they find a host cell.D. Viruses enter our bodies mainly through our mouthsnoses and hair.2. Which of the following might explain the origin ofviruses?A. They evolved from the fossils of large organisms.B.They evolved from parasites to independent organisms.C.They evolved from the DNA of animals.D. They evolved along with their host cells.3.What can we conclude from the text?A. Viruses live longer in human host cells thanin animals,.B. Viruses will become more like bacteria as they evolve.C. It may take a long time to understand the origin ofviruses.D. The author is confident of future virus research.BA new study predicts that warmer waters in the AtlanticOcean will continue to increase the number of majorhurricanes.The study, published in the journal Science, was basedon research carried out by the National Oceanic andAtmospheric Administration NOAA ) Researchers sayeach hurricane season is likely to produce five to eightmajor hurricanes by 2100. Since 2000, the Atlantic hasaveraged three major hurricanes a year. Before that, theaverage was closer to two.The new study used a computer modeling systemdeveloped by NOAA to create different climate conditions.Hiroyuki Murakami, a lead researcher on the study, saysthe climate simulation system is an effective tool tohelp estimate current and future storm activity. Murakami'steam found that a combination of natural conditions andman-made climate change is making the Atlantic Oceanwaters warmer. Man-made causes included the burning of coal, oil and gas.Warm water is important because it acts as a fuel forhurricanes. Water has to be at least 26 degrees Celsius for astorm to form. The warmer the water is, the more ahurricane can resist forces that would cause it to weaken.Some outside experts had issues with parts of Murakami's study. Brian McNoldy is a hurricane researcherat the University of Miami. He said that it made sense that unusually warm water caused the extra hurricane activity in2017. But he was not willing to completely blame climatechange. "Hurricane seasons don't just keep getting moreactive as the climate warms. There is enormousvariability,"McNoldy said.Kevin Trenberth is with the National Center forAtmospheric Research. He took issue with the fact that thestudy did not include research on large increases in oceanheat in deeper ocean areas. Trenberth said this could also becaused by climate change.1. Why did the researchers develop the computer modelingsystem?A. To predict storm activity.B.To make the weather forecast.C. To record the number of hurricanes.D. To measure the seawater temperature.2. What does the underlined word "it"refer to in Paragraph 4?A.A storm.B.A hurricane.C.Force.D. Water.3. What did other researchers think of Murakami's study?A.They couldn't agree with him more.B. They disagreed with him at all.C. They thought there were mistakes in it.D. They partially agreed with his findings.4. What is the passage mainly about?A. Reasons for the increase of hurricanes.B. Prediction and prevention of hurricanes.C. Research on warm waters and hurricanes.D. Research on the water temperature of the AtlanticOcean.二、完形填空阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最正确选项。Alexis Lewis, a 7-year-old girl, set out with herfamily on a trip to explore different parts of the country.During the hours on the road, her grandfathen a rocketscientist, would 1 cool ideas with Alexis about science.Eventually, everything her grandfather said_2 Alexis tobecome an inventor.Fast forwarded to the 2019 Kid Inventors' Day event 3 on January 17th in Brooklyn, New York, andAlexis, 14, was one of the seven kid 4 who attendedthe event.
