If maths is the language of the universe, bees may have just uttered their first words. New research suggests these busybodies of the insect world are capable of addition and subtraction (减法)—using colors in the place of plus and minus symbols.
In the animal kingdom, the ability to count—or at least distinguish between differing quantities—isn’t unusual: It has been seen in frogs, spiders, and even fish. But solving equations (方程式) using symbols is rare, so far only achieved by famously brainy animals such as chimpanzees and African grey parrots.
Building on previous research that says the social insects can count to four and understand the concept of zero, researchers wanted to test the limits of what their tiny brains can do.
Scientists trained 14 bees to link the colors blue and yellow to addition and subtraction, respectively. They placed the bees at the entrance of a Y-shaped maze (迷宫), where they were shown several shapes in either yellow or blue. If the shapes were blue, bees got a reward if they went to the end of the maze with one more blue shape (the other end had one less blue shape); if the shapes were yellow, they got a reward if they went to the end of the maze with one less yellow shape.
The testing worked the same way: Bees that “subtracted” one shape when they saw yellow, or “added” one shape when they saw blue were considered to have aced the test. The bees got the right answer 63% to 72% of the time, depending on the type of equation and the direction of the right answer—much better than random guesses would allow—the researchers report today in Science Advances.
Though the results came from just 14 bees, researchers say the advance is exciting. If a brain about 20,000 times smaller than ours can perform maths using symbols, it could pave the way to novel approaches in artificial intelligence (AI) and machine learning. Just don’t ask the bees to do your homework anytime soon.
1.Why do the scientists conduct the research?
A. To teach them maths. B. To test the power of tiny brains.
C. To explain the meaning of colors. D. To get access to machine learning.
2.What does the underlined word “aced” in Paragraph 5 probably mean?
A. Given up. B. Entered for.
C. Got through. D. Checked over.
3.What might the research make contributions to?
A. Language acquisition. B. Arithmetic learning.
C. Protection of animals. D. Development of AI.
4.What can be the best title for the text?
A. Bees “Like” Counting
B. Bees “Tell” Colors Apart
C. Bees “Perform” Maths Using Shapes
D. Bees “Get” Addition and Subtraction

高三英语单项填空简单题查看答案及解析
Many of us have heard of the saying: everything is possible if you can just believe. But few of us really know the power of faith and perseverance(坚定). South African swimmer Natalie du Tiot embodies(体现)those virtues.
Du Tiot, 24, became the first swimmer to compete in both the Olympic Games and the Paralympics (残奥会)in Beijing. Although she finished 16th in the tough 10km marathon in the able-bodied Games, she has collected three golds in the Paralympics so far.
One of the most successful disabled athletes of all time, Natalie du Tiot was already a promising swimmer when she lost her leg in a motorcycle accident in 2001, at just 17.
“There are a lot of dark moments,” she said, “There are some days when I cry. But I try to remember that better days are ahead. You just go on.”
Within a few months, she was back in the swimming pool.
She still completes and still succeeds. The only difference is she has switched to longer events—from 200m and 400m individual medley to 800m and 1,500m freestyle—to make up for her loss of speed with only one leg. But she made no adjustment to her mental look(精神面貌).
“Going out in the water, it feels as if there’s nothing wrong with me. It doesn’t matter if you look different. You’re still the same as everybody else because you have the same dream.”
She is the owner of many world records, and she also won gold when competing against able-bodied swimmers in the 1,500m freestyle at the All African Games in 2007.
But there is no magic recipe(秘诀) for success. It all comes down to hard work and determination. “She is stubborn, which is good and bad,” said her coach Karoly Von Toros. “Good for the swimming, but bad for the coach.”
There is a poem that hangs on her wall that reads:
The tragedy (悲剧)of life does not lie in not reaching your goals;
The tragedy of life lies in not having goals to reach for.
1. Natalie du Tiot is a vivid example that____________________.
A.you are what you believe |
B.your biggest enemy is yourself |
C.results are not so important as the process |
D.you must set reasonable goals or you will fail |
2.According to the text , Natalie du Tiot became________________.
A.the first athlete to compete with able-bodied swimmers in the world |
B.the youngest disabled swimmer to break the world record in the 1,500m freestyle |
C.the youngese disabled swimmer to collect three golds in a single Paralympics |
D.the first swimmer to compete in both the Olympic Games and the Paralympics |
3.Which of the following is the correct order of the events that happened to Natalie du Tiot?
a. She won gold at the All Africa Games.
b. She finished 16th in the tough 10km marathon in the Olympics
c. She adjusted herself to long events.
d. A motorcycle accident disabled her.
A.cdab | B.dcba | C.dcab | D.dacb |
4.In dark moments it was_______________ that pushed her on.
A.her coach | B.her family | C.hope and faith | D.her love of swimming |

Pinocchio may be just a children's fairy tale, but Spanish scientists at the University of Granada recently investigated the so-called ''Pinocchio effect'' and found that our noses don't grow when we tell a lie, but actually shrink a bit.
Dr. Emilio Gómez Milán and his team developed a lie detector test that used thermography to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tips of their noses dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientists also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.
''One has to think in order to lie, which rises the temperature of the forehead, '' Dr. Gomez Milan explained the findings. ''At the same time we feel anxious, which lowers the temperature of the nose. ''
For this study, researchers asked a number of 60 students to perform various tasks while being scanned by thermal imaging technology. One of these tasks involved calling a 3 to 4 minutes call to their parents, partner or a friend and telling a significant lie. Participants had to devise the lie by themselves during the call, and the thermal cameras picked up this ''reverse Pinocchio effect'' caused by the fluctuation (起伏) in temperature in the nose and forehead.
Interestingly, the thermal lie doctor picked up the temperature difference in 80 percent of test subjects, which is a better rate of success than that of any modern lie doctor.
''With this method we have achieved to increase accuracy and reduce the occurrence of 'false positives', something that is frequently with other methods such as the polygraph (测谎仪) , '' said Dr. Emilio Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.
The thermal lie doctor has been the most reliable in the world, 10% more than the popular polygraph.
1.Why does the author mention ''Pinocchio'' at the beginning?
A.To tell a fairy story B.To warn us not to lie.
C.To introduce a research. D.To inspire us to doubt old beliefs.
2.According to the research, what might happen if you tell a lie?
A.Your nose gets longer.
B.Your nose becomes smaller.
C.Your temperature gets higher.
D.Your temperature remains stable.
3.What can we learn about the research?
A.Researchers conduct the study by interviewing.
B.Researchers design difference lies for participants.
C.The thermal lie detector will prove a popular one.
D.The thermal lie doctor may assist law enforcement.
4.Which might be the best title for the passage?
A.Will lie detectors tell the truth?
B.Will lying make your nose longer?
C.Will lying make your temperature rise?
D.Will thermal imaging technology be reliable?
