It’s 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. scientific B. accurate

C. following D. exceptional

3.According to the passage, which of the following statements is NOT true?

A. Memory failure influences students’ study effects.

B. Bumblebees’ memory is complicated and worth studying.

C. The bees couldn’t make out which flower had rewarded them days later.

D. Bumblebees are stupid insects with limited brain capacity.

4. What does the test mentioned in Paragraph 4 tell us?

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.

5.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.

1.B

2.C

3.D

4.A

5.D

A study of more than five million books, both fiction and non-fiction, has found a marked decline in the use of emotional words over time. The researchers form the University of Bristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise.

They found that almost all of the categories showed a drop in these “mood words” over time. Only in the category of fear was there an increase in usage.

“It is a steady and continuous decrease,” said Dr Alberto Acerbi. He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape. “One thing could be that in parallel to books the 20th century saw the start of other media. Maybe these media — movies, radio, drama, had more emotional content than books.”

Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour:the ratio (比率) between the two varied greatly, apparently mirroring historical events.

During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash. But the ratio plunged at the height of the Second World War. Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends. In the paper, they even argue that the reverse could be true.

“It has been suggested, for example, that it was the suppression (压抑) of desire in ordinary Elizabethan English life that increased demand for writing ‘filled with romance and sex’… perhaps,” they conclude, “songs and books may not reflect the real population any more than catwalk models reflect the average body.”

Pablo Picasso was born in Spain in 1881. His father was an artist and also an art teacher. He gave little Picasso the first lesson in drawing.
