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. Nearly one quarter of the kids reported having no plain water.

People seem to believe that there's something magical about grapefruit — that, in some way, it helps burn fat. 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.

[话题感悟]

学习目标 ——语篇复现词汇，活学活用记忆更深

( 加蓝词汇为本单元话题词汇，读文时请揣摩其用法)

[1]We talk about food in the negative: What we shouldn't eat, what we'll regret later, what's evil, dangerously tempting and unhealthy.

[2]The effects are more harmful than any overindulgent (放纵的) amount of “bad food” can ever be. By getting anxious about food, we turn occasion for comfort and joy into sources of fear and anxiety. And when we avoid certain foods, we usually compensate by consuming too much of others.

[3]All of this happens under the cover of science. But a closer look at the research behind our food fears shows that many of our most demonized (妖魔化的) foods are actually fine for us. Taken to extremes, of course, dietary choices can be harmful — but that logic cuts both ways.

[4]Consider salt. It's true that, if people with high blood pressure consume a lot of salt, it can lead to cardiovascular events like heart attacks. It's also true that salt is overused in processed foods. But the average American consumes just over three grams of sodium (钠) per day, which is actually in_the_sweet_spot for health. Eating too little salt may be just as dangerous as eating too much. This is especially true for the majority of people who don't have high blood pressure. Regardless, experts continue to push for lower recommendations.

[5]Nevertheless, we've become more and more influenced by arguments that we must avoid certain foods completely. When one panic­causing item fades, we find another focus for our fears. We demonized fats. Then cholesterol. Then meat.

[6]Is it a problem that people want to avoid foods? The answer is: yes, because it makes food scary. Food should be a cause for pleasure, not panic. For most people, it's entirely possible to eat more healthfully without living in terror or struggling to avoid certain foods altogether. If there's one thing you should cut from your diet, it's fear.

语篇解读：本文主要讲述的是对食物的一些错误的恐惧认识，提倡快乐饮食、健康饮食。

1．What might be the result of avoiding certain foods, according to the author?

A．Becoming healthy.

B．Overeating other foods.

C．Regretting later.

D．Enjoying comfort and joy.

解析：选B　细节理解题。根据第二段最后一句“And when we avoid certain foods, we usually compensate by consuming too much of others.”可知，人们在避免某些食物时，会食用过量其他食物来进行补充，故选B。

2．What does the underlined phrase “in the sweet spot” in Paragraph 4 refer to?

A．Suitable.　　　　　　　　 B．Unclear.

C．Too much. D．Too little.

解析：选A　词义猜测题。根据第四段第四句的“But”转折，并与前两句形成对比可知，实际上普通美国人每天食用三克多一点儿的钠对健康是有利的，由此可推知，画线短语的意思是“合适的”，故选A。

3．By listing one food after another to fear, the author means that ________.

A．people are eating unhealthy food

B．the environment is unsafe

C．there's no point avoiding certain foods

D．people should be careful about food

解析：选C　推理判断题。根据对最后一段的整体理解可推知，作者罗列出人们所恐惧的食物的目的是提醒人们避免某些食物是不必要的，只要适量食用，对身体健康是没有坏处的，毕竟人们总是要吃饭的，吃饭是一种快乐而不是恐惧，故选C。

4．Which of the following can be the best title for the text?

A．Treating Food Negatively

B．Avoiding Food Skillfully

C．Consuming Salt Without Caution

D．Eating Food Without Fear

解析：选D　标题归纳题。根据第一段内容，并结合最后一段的点题可推知，本文主要讲述的是对食物的一些错误的恐惧认识，提倡快乐饮食、健康饮食，故选D。

学习目标 ——题后把脉规律，练后得法理解更透

主旨大意技法(2)——破解归纳标题的四大切入点

①标题形式：单词、短语或句子。

②标题特点：一个好的标题一般具有概括性、针对性和简洁性三个突出特点。

③选择方法：在了解文章大意的基础上，仔细考虑内容与文章主题是否有密切联系；看选项内容对文章的概括性和覆盖面如何；要注意题目范围过大或过小。

④设错方式：概括不够；过度概括；以事实细节替代概括性强的大意(如上文第4题A、C项)；无中生有，生搬硬套(如上文第4题B项)。

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。
