【题目】 According to a team of researchers，an animal's ability to perceive（感知）time is linked to their pace of life.

“Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures." commented lead author Kevin Healy from Trinity College Dublin.

The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs，for example，have eyes with a refresh rate higher than humans.

One example of this phenomenon at work，the authors say，is the housefly and its ability to avoid being hit. The research showed flies “observe motion in a shorter time than our own eyes can achieve，"which allows them to avoid being hit.

Professor Graeme Ruxton of the University of St Andrews in Scotland，who worked jointly on the research project，said in a statement，“Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus，this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers，but they can make good decisions very quickly. ”

In comparison，the tiger beetle（虎甲虫）runs faster than its eyes can keep up，basically becoming blind，which requires it to stop periodically to re-evaluate its prey's（猎物）position.

Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.

【1】What is the research mentioned in the passage mainly about？

A.Pace of life of animals.B.Impressive abilities of animals.

C.Lifetime of small animals.D.Time perception of animals.

【2】What does Kevin Healy's comment mean in Para.2？

A.The survival of fast moving animals relies on their ability to perceive time.

B.Animals with quicker pace of life have better perception of time.

C.The ability of animals to perceive time depends on their high moving speed.

D.Animals with poor ability of time perception have a shorter life.

【3】Why can houseflies avoid being hit？

A.They can think very deeply before they act.

B.They can process the information as quickly as they receive it.

C.They can fly much faster than their eyes can keep up.

D.They can send information to brain more quickly than to their eyes.

【4】What will a tiger beetle have to do to catch a moving prey？

A.Slow down to gain its time perception.

B.Prevent itself from becoming blind.

C.Stop occasionally to spot the prey again.

D.Try to run as fast as it can.

【答案】

【1】D

【2】A

【3】B

【4】C

【解析】

本文是一篇说明文，介绍了对动物时间感知的研究。

【1】细节理解题。根据第一段“According to a team of researchers，an animal's ability to perceive（感知）time is linked to their pace of life.”可知，据一组研究人员称，动物感知时间的能力与它们的生活节奏有关，由此可知，文中提到的这个研究是关于动物的时间感知的，故D项正确。

【2】推理判断题。根据第二段中的“the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures.”可知，对于能快速移动的动物而言，在极短的时间内感知时间的能力可能是生与死的区别，由此可知，Kevin Healy说的意思是快速移动的动物的生存依赖于它们对时间的感知能力，故A项正确。

【3】细节理解题。根据第四段中的“The research showed flies “observe motion in a shorter time than our own eyes can achieve，"which allows them to avoid being hit.”可知，家蝇观察物体运动的时间比我们人眼所能达到的时间要短，这使得它们能够避免被击中，再结合第五段中的“but they can make good decisions very quickly.”可知，它们可以很快做出好的决定，也就是说它们可以尽快处理收到的信息，故B项正确。

【4】细节理解题。根据倒数第二段中的“the tiger beetle（虎甲虫）runs faster than its eyes can keep up，basically becoming blind，which requires it to stop periodically to re-evaluate its prey's（猎物）position”可知，虎甲虫的移动比眼睛快，基本上是盲目的，这就要求它不时地停下来，重新评估猎物的位置，由此可知，为了抓住移动的猎物，虎甲虫需要不时地停下来确定猎物的位置，故C项正确。

Thank you very much!

【题目】 It was a little before nine o'clock on Tuesday night. 【1】 “Do you need a second helping of pudding?"a waitress asked. Antonio, who had already finished a plate of pasta,a Fish Stew and a slice of cake, couldn't answer it right away. The question might be common for most diners, but for him, it was entirely novel because he was homeless and was having the meal for free. 【2】 .He had no preparation for it.

【3】But at night, it transforms itself into a pioneering place where homeless people such as Antonio can dine free of charge, at tables set with flowers, metal cutlery（餐具）and proper glasses.

The restaurant is the latest initiative（初步行动）from the charity Mensajeros de la Paz.It was founded 54 years ago by Father Angel Garcia Rodriguez. Its business model – using breakfast and lunch takings from paying customers to fund free evening meals for the homeless - is simple enough. 【4】 “The inspiration came from Pope Francis, who's spoken again and again about the importance of giving people dignity, whether it's through bread or through work," said Father Angel. “ 【5】People with nothing can come and eat in the restaurant and get the same treatment as everyone else. It's just common sense."

A.By day, the Robin Hood restaurant, which sits on a side street near the center of Madrid,is a typical Spanish bar.

B.So we thought, why not open a restaurant with tablecloths, proper cutlery and waiters?

C.They plan to extend the scheme and hopes it will attract famous chefs to come to cook.

D.It was the first time that he had been asked such a question.

E.The homeless are treated with respect at the restaurant.

F.Antonio found himself facing a welcome dilemma.

G.Its aim, however, is a little ambitious.

【题目】 Ladies, if you find yourselves wandering an unknown city with a man who is questioning your directional abilities, don’t doubt yourselves.

A recent small study published in the journal Psychological Science found that the longstanding theory that women have a more difficult time reading maps wasn’t true.

Historically, men have performed better than women in studies that tested their spatial(空间的)ability. But the leading study author Margaret Tarampi and a researcher from the University of California, Santa Barbara theorized that social influences had an effect on this outcome: The cultural belief that women are worse at reading maps could be seen as a stereotype(固有模式) threat, meaning women believe they’re bad at something, so they perform poorly as a result. The researchers also theorized that women performed better at skills that involve a social element. In other words, if reading a map means helping someone else, they might perform better.

Tarampi and her team tested both theories on undergraduate students at UCSB across three separate experiments. And, indeed, the results showed that men scored better than women only when they were mentioned the stereotype of male superiority before the test.

When the researchers did not mention it and gave a social context for reading the map, women’s scores improved across the board. Women also performed better when the test maps simply included human figures, rather than just random objects and landmarks.

So ladies, next time you struggle to figure out whether you should make a left or right at the Louvre, take out your tourist map with a healthy dose of confidence.

D.To state a social phenomenon.

【2】Women are thought to be worse at reading maps because of .

A.a poor sense of directionB.a lack of experience

C.a social stereotypeD.threats from others

【3】Men performed better than women in the study when .

A.they were asked to help someone else by reading a map

B.they were informed of the stereotype before the test

C.the test maps simply included human figures

D.there were social elements in the map

【4】What can be concluded from the passage?

A.Women can read maps as well as men.B.Women are better drivers than men.

C.Women always have difficulty reading maps.D.Women are better at spatial ability.

【题目】Directions : Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

Environmental pollution kills 1. 7 million children under the age of five every year worldwide. This is according to the World Health Organization (WHO). The WHO warns that child deaths will increase greatly if pollution continues to worsen.

The most common causes of death among children aged one month to five years are diarrhea, malaria and pneumonia. This is according to the WHO. 【1】 This means providing access to safe water and sanitation, limiting exposure to dangerous chemicals, and improving waste management.

【2】 The WHO estimates that air pollution is responsible for about 6. 5 million premature, or early, deaths every year. That number includes nearly 600, 000 deaths of children under age five. Most of these deaths take place in developing countries.

Air pollution is a leveler between rich and poor, according to WHO environment and health chief Maria Neira. 【3】 And one of the most important ways to reduce air pollution is to produce cleaner fuels for cooking and heating. “Almost half of the world population is using dirty fuels for cooking, heating, and lighting at home. And, this is affecting very much mothers who are staying and cooking at home, but the children who are around mothers -- they are exposed as well. ” Early exposure to harmful pollutants can lead to increased risk of chronic respiratory disease, asthma, heart disease, stroke and cancer later in life.

Cleaning up how the world cooks, heats and lights homes and other buildings is a big- picture goal. The WHO is advising government departments and industries such as construction and the health sector to work together to clean up their environment.

【4】 The U. S. Environmental Protection Agency has the following suggestions:

Avoid walking where there is a high volume of vehicle traffic.

Equip homes with air filters and air conditioning units.

Limit your time outside if you live in an area that issues warnings about air quality.

Wear high-grade, rated face masks tightly to the face when air quality is poor.

Remove your clothes and wash immediately after entering your house if you live or commute in a very polluted area.

A. However, of all the environmental pollutants, air pollution is being called the most dangerous.

B. But what can individuals do to limit our family's exposure to air pollution?

C. Therefore, the WHO stresses that governments around the world need to take the lead on ensuring that children grow up in a clean environment.

D. The organization also says reducing environmental risks can prevent such deaths.

E. A polluted environment is a deadly one—particularly for young children.

F. Everybody, she says, needs to breathe.
