Erica Kenney, a scientist at Harvard's T．H. Chan School of Public Health, planned to ❶look_into (调查)the amount of sugary drinks kids drank at first. However, she found many kids had not enough water ❷to_drink (drink)．‎ Kenney and her team studied a group of 4,000 children, ❸aged (age) 6 to 19, between the years 2015 and 2018. She noticed that more than half of the kids were dehydrated. Boys were 76% more likely than girls ❹to_lack (lack) enough water.

But this is just scientifically rubbish. It's probably ❶based_on_the fact that, years ago, grapefruit juice was used by housewives for cleaning fat stains (污点). While it might be good at ❷breaking_down fat stains, it doesn't work like that once it's in the body. Others believe that it increases metabolism and helps burn fat. Again, no facts show that this is true.‎ What's the truth?‎ The American Dietetic Association has shown that this “longheld myth is wishful thinking” and that grapefruit doesn't help people ❸lose_weight or burn fat.‎ Of course, if you're only going to have half a grapefruit for breakfast ❹instead_of_several kinds of fatty foods, then you're going to lose weight. However, it ❺has_nothing_to_do_with grapefruit. It's just that you're having light meals.‎ So is there no hope?‎ The only way to lose weight is to watch what you eat and ❻take_some_exercise. Grapefruit ❼is_full_of_vitamins that the body needs, so it's a good food to include in your meals. But it's not going to make the pounds ❽drop_off magically.‎ 课下作业（二） 高考语篇提能练 A Screen time before bedtime may leave people feeling sleepy in the morning.Cell phones, computers and TVs emit (发出) blue light.And exposure to that bluish light during the two hours before bed can keep us from getting a good night's rest, a new study finds.It cuts down on the length of people's sleep.It also leaves them feeling tired in the morning and can disrupt the body clock.Data shows that this blue light tends to make us more alert at night, making it harder to get all the rest we need.‎ Green and his team surveyed 19 people — all in their 20s — for a sleep study.All spent two hours on a computer right before bedtime.But they didn't all experience the same light exposure.Looking at screens that gave off intense blue light cut someone's sleep by about 16 minutes, compared to when they had used screens with red light.Those exposed to blue light also woke up more often at night than if they had been exposed to red light.‎ ‎“The normal blue light emissions from the computer screen also affect how much melatonin (褪黑素) each volunteer makes.It is released into our blood around 9 p．m. When our bodies make less melatonin, we may still feel too alert at bedtime to fall asleep when the body is tired.And ‎ body temperature won't drop as expected after we use devices emitting lots of blue light.Using screens before bed damages the body's biological clock，” Green says.“More and more kids are using screens nowadays.Sleep is important, especially during the first few years of life when ‘neural plasticity’ (神经可塑性) is at its greatest.Their brains are still developing the ability to learn and pay attention.That makes the new results worrisome，” Green says.‎ Rahman says that the new work makes a good point about how blue light from screens can be bad for our bodies.However, he points out, the light in this study is extremely bright.It is far brighter than what a normal computer, tablet or TV will emit.Still, Rahman says the results remind us to think about how we should use screens before bed.‎ 语篇解读：本文是一篇说明文。文章主要介绍了屏幕发出的强烈蓝光对人们睡眠的影响。‎ ‎1．The blue light from the screens may cause people to ________.‎ A．tend to work at night B．get attentive in the morning C．be less sleepy before bed time D．be affected less by the body clock 解析：选C　细节理解题。根据第一段中的“Data shows that this blue light tends to make us more alert at night, making it harder to get all the rest we need.”可知，夜晚在屏幕的蓝光下会让人们更清醒。‎ ‎2．What is Paragraph 2 mainly about?‎ A．People's concern about light exposure.‎ B．A study on blue light's effects on sleep.‎ C．Reasons for blue light's effects on sleep.‎ D．Effects of various types of light on sleep.‎ 解析：选B　段落大意题。第二段介绍了Green小组关于蓝光对睡眠的影响的研究。‎ ‎3．What can be implied from Green's remarks?‎ A．Melatonin may affect people's neural plasticity.‎ B．Blue light may affect children's brain development.‎ C．Exposure to normal screen has little impact on sleep.‎ D．The low temperature of body helps produce melatonin.‎ 解析：选B　推理判断题。根据倒数第二段中的“More and more kids are using screens ...developing the ability to learn and pay attention.”可知，蓝光可能会影响孩子大脑的发育。‎ ‎4．What's Rahman's possible attitude towards the Green's study?‎ A．Uncaring.　　　　　　　 B．Approving.‎ C．Objective. D．Critical.‎ 解析：选C　观点态度题。根据文章最后一段“Rahman says that the new work makes a good point about how blue light from screens can be bad for our bodies.”可知Rahman对Green的研究持客观的态度。‎ B In our twenties, we find it funny when we can't remember our neighbor's cat's name or that handsome actor who starred in that movie — whatever it was called.In our thirties, we jokingly call it “brain freeze”．In our forties, we laugh it off as a “senior moment” and follow up with one of these oldage jokes.But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful.You think, “Am I losing it？” Or worse, “Is this a sign of Alzheimer's disease (老年痴呆症)？”‎ Well, don't worry: the fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease.A new study shows that it's not forgetfulness but not being aware that we're forgetful that we should fear.‎ The researchers began with the assumption that one common feature of Alzheimer's disease (AD) is a damaged awareness of illness.And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with “mild cognitive (认知的) damage” will progress to fullon AD.For the study, “mild cognitive damage” was defined as someone whose mental state was considered healthy but who had either complained of memory loss or had suffered objective memory loss.‎ The researchers used existing data for 1,062 people between the ages of 55 and 90 that had been recorded over a 12year period.The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake (葡萄糖摄入)．It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD.What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness.Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.‎ 语篇解读：本文是一篇说明文。研究发现，如果一个人能够意识到自己有些健忘，那这个人可能不会患老年痴呆症。‎ ‎5．What's implied in Paragraph 1?‎ A．Forgetting something is really embarrassing.‎ B．Sometimes even young people can be forgetful.‎ C．It's a bad sign when a young man forgets something.‎ D．Young people also show signs of Alzheimer's disease.‎ 解析：选B　推理判断题。根据第一段的“we find it funny when we can't remember our neighbor's cat's name ... we jokingly call it ‘brain freeze’”可知年轻人有时也会健忘。‎ ‎6．What does the underlined word “dreadful” in Paragraph 1 mean?‎ A．Confusing. B．Amazing.‎ C．Frightening. D．Disappointing.‎ 解析：选C　词义猜测题。根据第一段画线词后面的“You think, ‘Am I losing it？’ Or worse, ‘Is this a sign of Alzheimer's disease (老年痴呆症)？’”可知这种情况会“令人害怕”。‎ ‎7．What's the researchers' purpose of doing this study?‎ A．To test a theory they held.‎ B．To find a cure to Alzheimer's disease.‎ C．To confirm something they had discovered.‎ D．To find a way to predict Alzheimer's disease.‎ 解析：选A　细节理解题。根据第三段的“wanted to prove their theory that the lack of awareness can be used to predict ...”可知是为了测试他们持有的一个理论是否正确。‎ ‎8．Which of the following can be a sign of developing Alzheimer's disease?‎ A．Having higher intake of glucose.‎ B．Realizing one's own forgetfulness.‎ C．Reduced ability to take in glucose.‎ D．Expected increase in brain function.‎ 解析：选C　细节理解题。根据最后一段的“What the researchers also discovered was that ... were more likely to develop AD than those without.”可知葡萄糖摄取能力下降可能是患老年痴呆的一个信号之一。‎
