Its well known that our human memory can fail us. People can be forgetful, and they can sometimes also remember things incorrectly, with damaging consequences in the classroom, courtroom, and other areas of life. Now, researchers show for the first time that bumblebees(大黄蜂) can be unreliable witnesses too.
Bumblebees are rather clever animals, which explains why Chittka has been studying learning and memory in the insects for the last 20 years.
Most times when people have studied memory in animals, errors in performance have been taken to mean that the animals failed to learn the task or perhaps learned it and then forgot. But what if animals can experience a more interesting type of memory failure?
To find out, Chittka first trained bumblebees to expect a reward when visiting a yellow artificial flower followed by one with black-and-white rings. During subsequent tests, bees were given a choice between three types of flowers. Two were the types they’d seen in the training before. The third had yellow-and-white rings, representing a mixed-up version of the other two. Minutes after the training, the bees showed a clear preference for the flower that recently rewarded them.
One or three days later, however, something very different happened when the bumblebees’ memory was put to the test. At first, the bees showed the same preference displayed in the earlier tests, but as the time went on, they began selecting the flower with yellow rings, even though they’d never actually seen that one in training before.
Chittka says that insects make similar errors in the conjunction (结合) of long-term memories as humans do. The ability to extract (提取) common features between different events in the environment might come at the expense of remembering every detail correctly. In bees, with their limited brain capacity (容量), the pressure to store main features of several objects rather than each individual object might be much greater, compared with humans.
1.Which of the following might be the best title of the passage?
A. Human memory can fail sometimes.
B. Bumblebees make false memories too.
C. Humans are not as clever as bumblebees.
D. Bumblebees have extraordinary memory.
2.Which of the following is the closest in meaning to the underlined word subsequent?

A. Short-term memories serve the bees well.
B. The yellow artificial flower appeals to the bees.
C. Bumblebees like the flowers with yellow-and-white rings.
D. Bees have remarkable abilities to distinguish colors.
4. We can infer from the passage that ______.
A. Chittka thinks that bumblebees failed to remember the color of the flowers
B. Researchers have learned that bumblebees are unreliable animals
C. There exist no similarities between the memory errors in humans and bees.
D. It is less challenging for humans than bees to store main features of several objects.

Summary Writing
An Extension of the Human Brain
Other people can help us compensate for our mental and emotional deficiencies (欠缺)，much as a wooden leg can compensate for a physical deficiency . To be exact , other people can extend our intelligence and help us understand and adjust our emotions. When another person helps us in such ways , he or she is participating in what I’ve called a “ social prosthetic (义肢的) system.” Such systems do not need to operate face-to face , and it’s clear to me that the Internet is expanding the range of my own social prosthetic system . It’s already a big bank of many minds . Even in its current state , the Internet has extended my memory and judgment .
Regarding memory : Once I look up something on the Internet , I don’t need to keep all the details for future use ------I know where to find that information again and can quickly and easily do particularly striking when I’m writing ; I ‘m no longer comfortable writing if I ‘m not connected to the Internet. It’s become natural to check facts as I write, taking a minute or two to dip into PubMed, Wikipedia , or other websites.
Regarding judgment: The Internet has made me smarter in matters small and large . For example , when I ‘m writing a textbook , it has become second nature to check a dozen definitions of a key term , which helps me dig into the core and understand its meaning . But more than that , I now regularly compare my views with those of many others . If I have a “ new idea”, I now quickly look to see whether somebody else has already thought of it , or something similar-and I then compare what I think with what others have thought . This certainly makes my own views clearer . Moreover , I can find out whether my reactions to an event are reasonable enough by reading about those of others on the Internet .
