【題目】In the story of “The crow and the Pitcher” from Aesop’s Fables, a thirsty crow(烏鴉) drops stones into a narrow jar to raise the low level of water inside so he can take a drink.

Now scientists have evidence to back up that story. New Caledonian crows actually do understand how to make water displacement work to their advantage, experiments showed. The results suggest that the birds are, at least in some aspects, as smart as first-graders, according to the study.

Researchers, led by Sarah Jelbert at the university of Auckland in New Zealand, presented six crows with tubes filled with water. Inside the tubes, a worm or piece of meat on a piece of wood was floating, just out of reach of the crow. In front of the tubes, the researchers arranged a bunch of heavy rubber erasers that would sink, and light plastic objects that would float. The crows found out that they could drop the heavy objects into the tubes in order to raise the water level and get their snack.

However, the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow tube to get a snack, the researchers said. Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops. In contrast, it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn’t realize this, and most of them went for the wide tube first.

Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in small amount of water at the bottom.

1What does the text focus on?

A. Aesop’s prediction B. Crow’s intelligence

C. The development of crows D. Human-animal communication

2How did the crows get the worm in a tube in Sarah’ experiment?

A. By dropping in the heavy erasers. B. By removing the plastic objects.

C. By standing on the wood. D. By breaking the tube.

3What does the underlined part “the treat” in Paragraph 4 refer to?

A. The tube. B. The object.

C. The snack D. The water.

4What did the experiment with wide and narrow tubes show?

A. Crows are sensitive to surroundings.

B. Crows have the ability to recognize shapes.

C. Crows are cleverer than chimps and children.

D. Crows understand water displacement incompletely.

【答案】

1B

2A

3C

4D

【解析】烏鴉和投手的故事來(lái)自伊索寓言。一只口渴的烏鴉(烏鴉)滴石頭進(jìn)入了一個(gè)狹窄的jar提高低水平的水里面,所以他可以喝,F(xiàn)在科學(xué)家有證據(jù)支持這個(gè)說(shuō)法。

1B

推理判斷題。根據(jù)第二段中New Caledonian crows actually do understand how to make water displacement work to their advantage, experiments showed. The results suggest that the birds are, at least in some aspects, as smart as first-graders, according to the study.可知,這篇課文講的是Crow的智力。故選B。

2A

細(xì)節(jié)理解題。根據(jù)第三段中The crows found out that they could drop the heavy objects into the tubes in order to raise the water level and get their snack.可知,在Sarah的實(shí)驗(yàn)中烏鴉通過(guò)落下沉重的橡皮擦進(jìn)入管子里來(lái)得到蟲子。根據(jù)句意可知答案為A。

3C

詞義猜測(cè)題。根據(jù)第四段第一句the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow tube to get a snack, the researchers said. 研究人員說(shuō),這些鳥在實(shí)驗(yàn)中笨拙地進(jìn)行了實(shí)驗(yàn),在實(shí)驗(yàn)中,它們可以選擇將物體放入寬管或窄管中,以獲得零食?芍,Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops. (將物體放入狹窄的管道中,將會(huì)使水位上升更多,并在兩滴之后將其置于可及的范圍內(nèi)。)中的the treat指的是The snack。

4D

推理判斷題。根據(jù)第四段中Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops. In contrast, it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn’t realize this, and most of them went for the wide tube first.可知,烏鴉不完全理解水的位移。由此可知答案為D。

任何一篇文章中的句子在內(nèi)容上都不是絕對(duì)孤立的,都跟句子所在的段落及整整篇文章有關(guān)。利用上下文提供的情景和線索,進(jìn)行合乎邏輯的綜合分析進(jìn)而推測(cè)詞義,是閱讀過(guò)程中的一大關(guān)鍵,這也是近年來(lái)高考考查的熱點(diǎn)。最常見的就是利用上下文語(yǔ)境、常識(shí)和語(yǔ)法關(guān)系推斷詞義,抓住所需推斷詞匯前后的含義找出正確答案。本題第3小題是詞義猜測(cè)題,根據(jù)第四段第一句the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow tube to get a snack, the researchers said. 研究人員說(shuō),這些鳥在實(shí)驗(yàn)中笨拙地進(jìn)行了實(shí)驗(yàn),在實(shí)驗(yàn)中,它們可以選擇將物體放入寬管或窄管中,以獲得零食。可知,Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops.

【題目】 Skin cancer deaths among men have jumped sharply in wealthy nations since 1985, with death rates among women rising more slowly or even declining, researchers have told a medical conference in Glasgow.

Reasons for the difference between sexes are unclear but evidence suggests men are less likely to protect themselves from the sun or pay attention to public health warnings, Dorothy Yang, a doctor said.

More than 90% of melanoma (黑素瘤) cancers are caused by skin cell damage from exposure to the sun or other sources of ultraviolet (UV) radiation, according to the US Centers for Disease Control.

In eight of 18 developed countries examined, men’s skin cancer death rates had increased in the past 30 years by at least 50%.

But the nations with the biggest rise in skin cancer deaths were often not those with the highest death rates, the research showed. In Australia, for example, nearly six out of every 100,000 men died of the disease in 2013 -2015. That is twice the second highest death rate (Finland), but only a 10% increase compared to 30 years earlier.

Australia has been an early performer of public health media campaigns since the 1970s to promote sun-smart’ behaviour. While debate continues on how much of Australia’s record skin cancer rate originates from the sun, 30 years of public health campaigns have no doubt made Australians acutely aware of the dangers.

Skin cancer deaths among women in 1985 in Australia occurred at half the rate as for men, and declined by 10% over the next 30 years. In other countries, female death from the disease went down over the same period. In some other sun-loving nations, however, women saw at least as sharp a jump from 1985 to 2015 in death rates as men.

Scientists are studying whether biological or genetic factors might also play a role in skin cancer, but findings so far are inconclusive.

1What can be concluded from the passage?

A.Death rates among women are declining all the time.

B.Australia is the first country to conduct public health media campaigns.

C.Death rate of skin cancer in Australia was once the highest.

D.Female death rate of skin cancer in some sun-loving countries went down.

2What probably keeps people away from skin cancer according to the text?

A.Declining exposure to UV.

B.Biological or genetic factors.

C.People’s love for sun.

D.People paying little attention to public health warnings.

3What does the underlined word “inconclusive” in the last paragraph probably mean?

A.Unclear.B.Evident.C.Definite.D.Satisfying.

4What’s people’s attitude to public health campaigns in Australia?

A.Doubtful.B.Positive.C.Critical.D.Controversial.

【題目】Sleep Tips: Steps to Better Sleep

Think about all the factors that can influence a good night’s sleep from work stress and family responsibilities to unexpected challenges. 1 While you might not be able to control the factors that affect your sleep, you can adopt habits that encourage better sleep.

Stick to a sleep schedule.

The recommended amount of sleep for a healthy adult is at least seven hours. Most people don’t need more than eight hours in bed to achieve this goal. 2 Try to limit the difference in your sleep schedule on weeknights and weekends to no more than one hour. If you don’t fall asleep within about 20 minutes, leave your bedroom and do something relaxing. Go ahead to bed when you’re tired. Repeat as needed.

Pay attention to what you eat and drink.

Don’t go to bed hungry or full. In particular, avoid heavy or large meals within a couple of hours of bedtime. 3 Nicotine, coffee and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine take hours to disappear. And even though alcohol might make you feel sleepy, it can interrupt sleep later in the night.

Create a restful environment.

Create a room that’s ideal for sleeping. Often, this means cool, dark and quiet. 4 Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.

Limit daytime naps.

Long daytime naps can affect nighttime sleep. If you choose to nap, limit yourself to up to 30 minutes and avoid doing so late in the day. If you work nights, however, you might need to nap late in the day before work to help make up for sleep debt.

5

Regular physical activity can promote better sleep. Avoid being active too close to bedtime it raises your body temperature so that your sleep is disturbed. However, spending time outside every day might be helpful, too.

A.Your discomfort might keep you up.

B.It’s no wonder that quality sleep is sometimes difficult to get.

C.Sleeping with light on might make it more challenging to fall sleep.

D.Go to bed and get up at the same time every day.

E.Know how to manage worries.

F.Include physical activity in your daily routine.

G.Read or listen to relaxing music.

Apologizing can be harder than realizing you’ve acted poor. To truly apologize to a friend, you had to be sincere and let your friend to know how much he means to you. It’s easy said than done. But if you swallow your pride and show some sincere regret, they will have a true apology ready. Besides, sending gifts can be good choice for you to make.
