9、ns Air Transport Auxiliary( ATA) during World War II.Mary Wilkins was born on Feb.2, 1917. When she was 8, her father bought her a ride in a plane. From there, she was hooked. As a teenager, she persuaded her father to pay for flying lessons, and she earned her pilots license at 22 in 1939.In 1940,s
10、he heard an ad for volunteer pilots to help the war effort. She signed up and joined the ATA, whose task was to deliver planes from factory to base or from base to factory for repairs.At the height of World War II, 26-year-old Mary Wilkins climbed down a ladder from the cockpit (驾驶舱) of a bomber(轰炸机
11、) at a Royal Air Force base in England.“Wheres the pilot? someone on the ground asked.“I am the pilot! she responded. She had delivered the bomber alonealthough built for a five-man crewfrom its factory. People on the ground looked at her in surprise. One of them even decided to climb up the ladder
12、to check the plane for the “missing” pilot.She was one of the “Atagirls, as they were nicknamed, who almost always flew without other crew members, compass or radio assistance. They guided themselves by using maps and following rives or railway lines. While they did not fly in combat(战斗), they faced
13、 the daily danger of attack by enemy planes. Mrs. Ellis was once shot at over Bournemouth, in southern England, by “friendly fire” from the ground. Another time, she had a near-miss when landing in thick fog at the same time a combat Spitfire landed on the same runway from the opposite direction. Th
14、at experience won her the nickname “the fog flyer .In all, Mrs. Ellis flew more than 1,000 warplanes of 76 typesincluding 400 Spitfiresamong more than 200 British airfields from 1942 to the end of the war in 1945.4. What does the underlined word “hooked” mean in the second paragraph? A. Touched. B.

17、es by radio when flying.CWhat kind of rubbish are you? This question might normally cause anger, but in Shanghai it has become a special greeting among people over the past week. On July 1st, the city introduced strict trash-sorting regulations(条例)that are required to follow and expected to be used
18、as a model for our country. Residents must divide their waste into four separate categories and toss (投放)it into specific public dustbins. They must do so at specified times, when monitors are present to ensure correct trash-tossing and to ask the nature of ones rubbish. Individuals who fail to foll
19、ow the regulations face the possibility of fines and worse. They could be punished with fines of up to 200 yuan ($ 29). For those who repeat to go against them, the government can add black marks to their credit records, making it harder for them to get bank loans or even buy train tickets.Shanghai
20、government is responding to an obvious environmental problem. It generates 9 million tons of garbage a year, more than Londons annual output, which is rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to sift(筛选)through the waste, pi
21、cking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up.Many residents appear to support the idea of recycling in general but are annoyed by the details. Rubbish must be divided according to whet
22、her it is food, recyclable, dry or harmful, the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules concerning food waste. They must put it straight in the required public bins, forcing them to tear open plastic bags and toss it
23、by hand. What they complain most is the short periods for dropping trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.8.What do we kn

27、chnology has become so advanced that the previously impossible seems to occur on a daily basis. And yetwe still have no cure for the common cold.Why cant we stop the common cold? According to Peter Barlow, a scientist at Edinburgh Napier University, the main challenge lies in the many different type
28、s of cold viruses that belong to the rhinoviruses(鼻病毒). There are at least 160 types. They mutate(突变) so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isnt likely to work on every type of cold.However, researchers from Sta
29、nford University and the University of California, San Francisco, have found a possible answer. They discovered a protein(蛋白质) that the viruses need. All the viruses were unable to replicate(复制) inside cells without a gene that produces a specific protein called SETD3.To identify the gene which prod
30、uces the specific protein, researchers used a gene-editing technique to test all genes in the human genome (基因组). Namely, they randomly disabled a single gene in each of the cells, so that the cells lacked one or another of every gene in our genome. These genetically modified cells were then exposed
31、 to the rhinoviruses, which cause the common cold. The team then looked at which gene was missing in cells that continued to grow. As it turned out. the one that stood out was SETD3, which makes a protein of the same name.Carette said the plan is to find a drug which can temporarily disable the prot
32、ein, instead of producing genetically modified humans. “We have identified a fantastic target that all rhinoviruses require and depend on. Take that away and the virus really has no chance, said Carette.12. Which does Peter Barlow think is a problem for fighting the common cold? A. The poor immunity
33、 of patients.B. The large variety of viruses. C. The lack of enough cures.D. The side effects of drugs.13. What do we know about the gene- editing study in Paragraph 4? A. All genetically modified cells survivedB. Some genes in our genome were ignored C. It located the gene responsible for SETD3D. I
