【題目】 Now, you may be thinking, “Oh my goodness, how do I start to get better sleep? 【1】” Well, beyond avoiding the damaging and harmful impact of alcohol and caffeine on sleep, and if you’re struggling with sleep at night, avoiding naps during the day, I have two pieces of advice for you.

The first is regularity. Go to bed at the same time, wake up at the same time, no matter whether it’s the weekday or the weekend. Regularity is king, and it will anchor your sleep and improve the quantity and the quality of that sleep.

【2】 Your body needs to drop its core temperature by about two to three degrees Fahrenheit (華氏) to initiate sleep and then to stay asleep, and it’s the reason you will always find it easier to fall asleep in a room that’s too cold than too hot. So aim for a bedroom temperature of around 65 degrees, or about 18 degrees Celsius (攝氏度). 【3】

And then finally, in taking a step back, then, what is the mission-critical statement here? Well, I think it may be this: sleep, unfortunately, is not an optional lifestyle luxury. 【4】 It is your life-support system, and it is Mother Nature’s best effort yet at immortality (長生不老). And the decrease of sleep throughout industrialized nations is having a disastrous impact on our health, our wellness, even the safety and the education of our children. 【5】 And it’s fast becoming one of the greatest public health challenges that we face in the 21st century.

A.Is it a good idea to stay up?

B.The second is keep it cool.

C.It’s a silent sleep loss disease.

D.Sleep is a biological necessity.

E.What are your tips for good sleep?

F.That’s going to be the best option for the sleep of most people.

G.You can’t update your memory if you don’t have enough sleep.

【答案】

【1】E

【2】B

【3】F

【4】D

【5】C

【解析】

這是一篇說明文。21世紀(jì)威脅公眾健康的最大挑戰(zhàn)之一就是睡眠缺失癥，那如何能睡個好覺，本文提出了兩點建議，同時說明了睡眠對人的重要性。

【1】

根據(jù)上文Oh my goodness, how do I start to get better sleep?可知哦，我的天哪，我怎么才能睡得更好呢？以及空的后一句 if you're struggling with sleep at night, avoiding naps during the day, I have two pieces of advice for you.可知如果你晚上睡不好覺就要避免在白天睡覺，我有兩條建議。由此可知，本句是在詢問如何睡好覺。故E選項“你有什么好的睡眠秘訣嗎？”符合上下文語境，故選E。

【2】

根據(jù)后文Your body needs to drop its core temperature by about two to three degrees Fahrenheit to initiate sleep and then to stay asleep, and it’s the reason you will always find it easier to fall asleep in a room that’s too cold than too hot.可知你的身體需要降低核心溫度大約2到3華氏度來開始睡眠，然后保持睡眠狀態(tài)，這就是為什么你會發(fā)現(xiàn)在一個冷的房間里比在一個熱的房間里更容易入睡。由此可知，本句為第二條建議，是保持涼爽。故B選項“第二點是保持涼爽”符合上下文語境，故選B。

【3】

根據(jù)上文So aim for a bedroom temperature of around 65 degrees, or about 18 degrees Celsius.可知臥室的溫度要控制在65華氏度左右，或者大約攝氏18度。由此可知，本句承接上文說為什么要這么設(shè)置溫度——對于大多數(shù)人來說，這是最好的睡眠選擇。故F選項“對于大多數(shù)人來說，這是最好的睡眠選擇”符合上下文語境，故選F。

【4】

根據(jù)后文It is your life-support system, and it is Mother Nature’s best effort yet at immortality.可知它是你的生命維持系統(tǒng)，也是大自然母親為永生所做的最大努力。由此可知，睡眠是一個不容置疑的生理需要。故D選項“睡眠是一種生理需要”符合上下文語境，故選D。

【5】

根據(jù)上文And the decrease of sleep throughout industrialized nations is having a disastrous impact on our health, our wellness, even the safety and the education of our children.可知整個工業(yè)化國家睡眠的減少對我們的健康，甚至我們的孩子的安全和教育造成了災(zāi)難性的影響。以及后文And it’s fast becoming one of the greatest public health challenges that we face in the 21st century.可知它正迅速成為我們在21世紀(jì)面臨的最大的公共衛(wèi)生挑戰(zhàn)之一。由此可知，本句承接上文說明，睡眠的減少導(dǎo)致的是睡眠缺失癥，且它正迅速成為我們在21世紀(jì)面臨的最大的公共衛(wèi)生挑戰(zhàn)之一。故C選項“這是一種無聲的睡眠缺失癥”符合上下文語境，故選C。

【題目】 The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.

That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.

“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.

For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.

In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.

【1】What does the underlined word “that” in paragraph 2 refer to?

A.Increased length of green lights.B.Shortened traffic signal cycle.

C.Flexible timing of traffic signals.D.Smooth traffic flow on the road.

【2】What does Kevin Balke say about adaptive signals?

A.They work better on broad roads.

B.They should be used in other cities.

C.They have greatly reduced traffic on the road.

D.They are less helpful in cities seriously jammed.

【3】What can we learn from Bellevue’s success?

A.It is rewarding to try new things.B.The old methods still work today.

C.I pays to put theory into practice.D.The simplest way is the best way.

On Knowing the Difference

It is as though we can know nothing of a thing until we know its name. Can we be said to know what a pigeon is unless we know that it is a pigeon? We may have seen it again and again, and noted it as a bird with a full bosom and swift wings. But if we are not able to name it except vaguely as a “bird”, we seem to be separated from it by a vast distance of ignorance. Learn that it is a pigeon however, and immediately it rushes towards us across the distance, like something seen through a telescope. No doubt to the pigeon fancier (愛好者) this would seem but the most basic knowledge, and he would not think much of our acquaintance with pigeons if we could not tell a carrier from a pouter. That is the charm (魅力) of knowledge—it is merely a door into another sort of ignorance.

There are always new differences to be discovered, new names to be learned, new individualities to be known, new classifications to be made. No man with a grain of either poetry or the scientific spirit in him has any right to be bored with the world, though he lived for a thousand years.

There is scarcely a subject that does not contain sufficient differences to keep an explorer happy for a lifetime. It is said that thirteen thousand species of butterflies have already been discovered, and it is suggested that there may be nearly twice as many that have so far escaped the naturalists Many men give all the pleasant hours of their lives to learning how to know the difference between one kind of moth (蛾) and another. One used to see these moth-hunters on windless nights chasing their quarry fantastically with nets in the light of lamps. In chasing moths, they chase knowledge. This, they feel, is life at its most exciting, its most intense.

The townsman passing a field of sheep finds it difficult to believe that the shepherd can distinguish between one and another of them with as much certainty as if they were his children. And do not most of us think of foreigners as beings who are all turned out as if on a pattern, like sheep?

Thus our first generalizations spring from ignorance rather than from knowledge. They are true, as long as we know that they are not entirely true. As soon as we begin to accept them as absolute truths, they become lies. I do not wish to deny the importance of generalizations. It is not possible to think or even to act without them. The generalization that is founded on a knowledge of and a delight in the variety of things is the end of all science and poetry.
