舒城县2023年考研英语一临考冲刺试卷Section I Use of EnglishDirections:Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on the ANSWER SHEET. (10 points) On July 24, 1916, a natural gas explosion trapped 32 men working in a tunnel 250 feet below Lake Erie. The first rescuers who entered the tunnel were 1 by gas, and for hours no one else dared to enter the suffocating (窒息的), 2 deathtrap.Then, late that night, someone had an idea: 3 Garrett Morgan and his new invention. Garrett Morgan was a successful 4 owner in Cleveland. The son of freed slaves and the seventh of 11 children, mechanically minded Morgan had opened his own sewing machine shop, which he soon 5 to a tailoring factory with 32 employees.In the early 1900s, factory buildings were crowded and untidy. They were often 6 of wood, with no fire escapes. Fire could cause serious 7 . Concerned about his employees, Morgan 8 with a “safety hood” (头罩) that would allow the wearer to 9 despite a fires poisonous smoke.Morgan knew smoke rises during a fire. 10 , he created a heat-resistant hood with a long tube reaching to the floor. Wearing Morgans hood, a firefighter could breathe the 11 air near the 12 Morgan lined the breathing tube with a sponge-like material that was wetted before use to 13 the air. A second tube was designed to 14 exhaled (呼出的) air.Called to the scene on the night of the tunnel explosion, Garrett arrived with samples of his safety hood. Still in their nightwear, he and his brother Frank put on the hoods and 15 entered the tunnel. It was a dangerous 16 of the invention, but they saved two lives and 17 four bodies before officials closed the 18 . Morgan knew that more lives might have been saved if he had been called sooner.The daring 19 made Morgan famous and brought requests for safety hoods from fire departments around the country. But his greatest 20 was knowing that his invention would now save more people.1、AlitBpoweredCovercomeDoverheated2、AchangeableBremarkableCcautiousDpoisonous3、Ashow offBsend forCrule outDtake away4、AfactoryBslaveCrestaurantDstore5、AdeclinedBdecidedCexpandedDexported6、AafraidBtrueCconsistedDmade7、AbusinessBdamageCillnessDdoubts8、AexperimentedBassociatedCequippedDstruggled9、AexistBcommunicateCbreatheDlisten10、AThereforeBHoweverCAnywayDBesides11、AcleanerBthickerCcolderDwarmer12、AceilingBgroundCroofDwindow13、AfeelBtrapCcoolDheat14、Aput onBget offCpolluteDrelease15、AunwillinglyBbravelyCgraduallyDsimply16、AtaskBtestCgameDpart17、AoverlookedBidentifiedCrecoveredDburied18、AgapBcaseCdealDsite19、ArescueBattemptCreformDescape20、AfortuneBcomfortCachievementDrewardSection II Reading ComprehensionPart ADirections:Read the following four texts.

(40 points)Text 1 Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mices genes are so similar to humans, their findings could lead to the treatment of more genetic diseases.Scientists at the University of California, Davis studied information from a data bank of mices genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.“This is extremely valuable for people with hereditary eye disease,” said researcher Professor Ala Moshiri. “All researchers are going to start using these data. In the past, we knew the problem was there but we didnt know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable.” Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the babys parents!Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mices genes
