高二英语单项填空中等难度题查看答案及解析

It's 3 a.m. and you're wide awake for the second night in a row. You get up and come to the kitchen for some warm milk that mom says will put you to sleep. So why are you eating a bowl of ice cream with a side of cookies?

You may have heard about two hormones (荷尔蒙) that control our urge to eat: leptin and ghrelin. "The 'l' in leptin stands for lose: It controls appetite and therefore contributes to weight loss," said sleep specialist Dr. Raj Dasgupta, the associate program director of the Sleep Medicine Fellowship at Keck Medicine of USC. "The 'g' in ghrelin stands for gain: This fast-acting hormone increases hunger and leads to weight gain." When you don't have enough sleep, research shows, ghrelin levels increase while leptin lakes a nose dive. The result is an increase in hunger.

But food is food, so that doesn't explain why we want candy instead of carrots. To answer that, you have to look at another system of the body: The endocannabinoid (内源性大麻素) system. It manages everything from sleep to appetite to pain and more.

In a study published in 2016, Hanlon compared the circulating levels of 2-AG, one of the most abundant endocannabinoids,in people who got four nights of normal sleep (more than eight hours) with those in people who only got 4.5 hours. People who were sleep-deprived (缺乏睡眠) reported greater increases in hunger and appetite and had higher afternoon concentrations of 2-AG than those who slept well. They also had a rough time controlling their urges for high-calorie snacks.

All of this research is so new that science doesn’t yet know how it all fits together or what can be done about it. And that brings us to the bottom line: There's not going to be a pill any time soon for the sleep-deprived junk-food people. Instead, you'll have to do what the doctor says to reduce your improper cravings (渴望) in the middle of the night: get more sleep.

1.How does the author develop paragraph 2?

A.By giving examples. B.By making comparisons.

C.By following time order. D.By making explanations.

2.What did the study published in 2016 find?

A.Most 2-AG is produced during sleep.

B.Normal sleep makes levels of 2-AG go up.

C.High levels of 2-AG can result in strong appetite.

D.Lack of sleep decreases appetite for high-calorie food.

3.What may be a solution to the problem of eating junk-food at midnight?

A.Buying a pill from the hospital. B.Visiting the doctor at midnight.

C.Getting normal amount of sleep. D.Checking the levels of 2-AG often.

4.What can be the best title for the text?

A.Lack of sleep makes you crave junk food.

B.2-AG controls your hunger and appetite.

C.Enough sleep is important in losing weight.

D.Leptin and ghrelin together make you sleepy.

You get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction.

For some people, smart phones have set them free from the nine-to-five work. Flexible working has given them more control over their working lives and enabled them to spend more time with their friends and families. For many others though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.

Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they’re spending on the device and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.

1.What’s the first paragraph mainly about?

A. The popularity of smart phones.

B. The progress of modern technology.

C. The signs of “always on” stress.

D. The solutions of smart phone addiction.

2. Kevin Holesh developed Moment to __________.

A. research how people use their mobile phones

B. help people control their use of mobile phones

C. make people better use mobile phones

D. increase the fun of using mobile phones

3.What’s Dr. Christine Grant’s attitude towards “always on” culture?

A. Confused.　　　　　　 B. Positive.

C. Doubtful.　　　　 　 D. Critical.

4. According to the last paragraph, a greater amount of data means __________.

A. we will become less productive　

B. we can make a decision more quickly　

C. we will be equipped with more knowledge　

D. we can work more effectively

If you are in a dilemma about being self-taught or getting formal education, you have come to the right webpage. In this article, we note the advantages of each of these to help you decide which one would be the best for you.

Perhaps the biggest advantage of being self-taught is that you are able to save a lot of money. With each passing year, the cost of getting a degree is on the rise. As a result, many students these days tend to graduate from college with a significant amount of debt. This makes it necessary for them to get a job as soon as possible, otherwise a number of serious issues may arise. Besides, it is possible to learn faster on your own, by focusing on only those areas that you are interested in. Finally, learning on your own can be a great confidence builder. You have to struggle to gain knowledge but once you clear the basics on your own, you will find yourself being much more confident about your abilities.

One of the biggest advantages of formal education is that you get a degree which is a mark of recognition that you have achieved a level of knowledge in that particular field. Many companies tend to prefer candidates who have a college degree. What’s more, though formal education lacks the convenience and flexibility of self-education, it offers you much more in terms of the actual structure of the learning process. Last, being formally educated means that you will enter a college or other similar educational institutions. There you will get the benefit of being taught and guided by learned teachers and other subject experts. This will be a big benefit as you will be able to lake advantage of their experience and gain in-depth knowledge about the subject.
