(2019·河北衡中质检)Strangely，scientists still haven’t figured out why sleep is so important for our survival.But they do know that not getting enough sleep prejudices our health.Now，a study of Northwestern University proves that having a light on while sleeping can rai your risk of diabetes(糖尿病)．
For the study，rearchers recruited 20 healthy adult volunteers (ages 18 to 40)．The voludetermine
axnteers spent two nights and three days at the lab: The first night，they slept in total darkness; the cond night，half of them slept in the dark again while the other half slept with a bright overhead light on.While the volunteers slept，the rearchers tracked the volunteers’ vital signs，brain wave activity，and took hourly blood samples.In the morning，they conducted gluco tolerance (葡萄糖耐量) tests on the volunteers.
Remarkably，just sleeping under a bright light incread insulin (胰岛素) resistance，a phenomenon that insulin can’t play its normal role.When insulin can’t do its job well，the body struggles to process sugar，which is one of the reasons for getting diabetes.“Our findings show that a single night of light exposure during sleep greatly impacts measures of insulin resistance，” said lead author Ivy Cheung Mason.
“Previous rearch has linked poor sleep to a higher risk of depression and breast cancer.Now our findings add dias such as diabetes to the list.Sleep disturbances affect more than 25 per cent of the general population and up to 50 per cent of Improving sleep in adults reprents a muchneeded approach to the prevention and treatment of type 2 diabetes.”
Although this is primary rearch，it does support the idea that you should avoid falling asleep on the sofa and spending part—or most—of the night with the lights and the TV on.

C．The risk of suffering from diabetes.
D．The decrea of the blood sugar level in the body.
答案 C [细节理解题。依据第三段中的“just sleeping under a which is one of the reasons for getting diabetes”可知，身体出现抗胰岛素性时，胰岛素不能发挥正常功

答案 D [推理判断题。依据第四段中的“Previous rearch diabetes to the listavenue”可知，糟糕的睡眠会导致人们患抑郁症和乳腺癌的风险增加，现在新的研究表明，睡眠不佳还会导致患糖尿病的风险增加，由此可知，抑郁症和糖尿病均可由睡眠问题导致。]
3．What does the author do in the last paragraph?

(2019·诸暨中学模拟)When Jocelyn Bell Burnell began her doctoral studies in physics at the University of Cambridge in 1965，she was convinced that they had made a mistake of admitting her.“I’m not bright enough for this place，” she thought.
She was one of only two women in her graduate program.Bell Burnell’s respon was to work as hard as she possibly could.Her efforts ended up paying off.Two years after she arrived at Cambridge，Bell Burnell discovered the first pulsar(脉冲星)—a groundbreaking discovery that in 2018，half a century after her pioneering work，earned her the $3 million Special Breakthrough Prize in Fundamental Physics，which was previously awarded to Stephen Hawking，for example.
“The discovery was one of the biggest surpris in the history of astronomy，transformin
四级高频词汇g neutron stars (中子星) from science fiction into reality in a most dramatic way，” the Breakthrough Prize committee said.“It led to veral powerful tests of Einstein’s theory of relativity，and a new understanding of the origin of the heavy elements in the univer.口号英语翻译”To Bell Burnell’s admirers，the prize is richly derved and somewhat overdue(早该发生的)．In 1968，when Bell Burnell and her doctoral advir published a paper detailing the discovery，it attracted international attention.The media didn’t know what to do with a young female scientist who had made a major breakthrough.Then，Hewish，her doctoral advir，was awarded the 1974 Nobel Prize in Physics “for his decisive role in the discovery of pulsars”．Being overlooked by the Nobel committee didn’t surpri her.It was just how things worked back then: professors，not students，got the credit.
