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.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. |

B.Bumblebees’ memory is complicated and worth studying. |

D.Bumblebees are stupid insects with limited brain capacity. |
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. |
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. |
Many people have described television as a passive activity that is harmful to children's education. However, there are good and bad ways to watch television. Parents who are interested in exploiting television as a learning tool can actually turn time in front of TV into an educational chance.
Probably the most familiar educational way to use television is to simply watch educational programs. In particular, this means selecting channels and programs specially designed for educational purposes. Along with traditional educational shows for children on public broadcasting channels, cable television (有线电视) now offers kids and adults a wide variety of educational programs, with everything from nature shows to historical events in different countries.
Captioning(字幕),such as "closed captioning" for hearing disabled viewers provides another way for parents to exploit the educational possibilities of television.One study showed that children who watched captioned TV got great improvement in their vocabulary and oral reading ability. In addition, parents can make any show a learning class by watching television together with children. By actively joining children in the programs that they are watching, parents can help with the development of such skills as predicting(预见)and summarizing. In order to develop predicting skills, parents and children could first refer to a program’s description in a viewing guide.After reading the program description and guessing what might happen in the program, parents and children could watch together to see which predictions were correct. And to practice summarizing, after watching a program, parents can turn off the TV and ask what the story was about. This kind of activity helps children develop thinking skills such as arranging events in an order and memorizing information.
Although there will still be plenty of times when children watch TV simply for passive enjoyment, parents can help make at least part of their children’s viewing time a more productive activity.Used intelligently by exploiting the learning chances available through various programs, television can play an instructive role in children’s education.
49. Which activity is NOT suggested in the passage?
A. Talking about TV shows. B. Watching captions on TV.
C . Enjoying films about nature. D. Watching shows for homework.
50.Which of the following statements is true according to the passage?
A. Parents can simply make any show a learning class for their children.

C. Most parents have changed their attitude to their kids’ watching TV and become positive to the problem.
D. In a way, it is how parents act that leads to whether watching TV may do good or not to their children.
51. We can infer from the last paragraph that.
A. not every minute when a child watches television must be educational
B. children should not use television for passive enjoyment
C. some children prefer reading to watching television
D. television offers more learning chances than school
52.Which of the following questions is the major one discussed in the passage?

This story is about a 92-year-old, short, well-behaved and proud lady. She is fully dressed each morning by eight, with her hair fashionably done and makeup perfectly applied, even though she is totally blind. She is moving to a nursing home today. Her husband of 70 years recently passed away, making the move necessary.
After many hours of waiting patiently in the hall of the nursing home, she moved to the elevator, I provided a visual description of her tiny room, including the eyelet(观察孔) sheets that had been hung on her window.“I love it,” she stated with the enthusiasm of an eight-year-old girl having just been presented with a new puppy.
“Mrs. Jones, you haven't seen the room yet. Just wait.” “That doesn't have anything to do with it,” she replied. “Happiness is something you decide on ahead of time. Whether I like my room or not doesn't depend on how the furniture is arranged, it's a decision I make every morning when I wake up.”
“I have a choice; I can spend the day in bed recounting(叙述) the difficulty I have with the parts of my body that no longer work, or get out of bed and be thankful for the ones that do. Each day is a gift, and as long as my eyes open I'll focus on the new day and all the happy memories I've stored away, just for this time in my life. Old age is like a bank account, you withdraw(收回) from what you've put in. So, my advice to you would be to deposit(储蓄) a lot of happiness in the bank account of memories.

Marie Sklodowska was the daughter of a Polish teacher. She was a very intelligent little girl; she could read when she was only four years old. Her father taught science at a school in Warsaw. Marie went to his school when she was fourteen years old. She was very interested in science and mathematics, and liked to help his father in his laboratory. She was a very good student and left school with a gold medal.
Marie wanted to be a scientist like her father. In 1891 her sister Bronya invited her to go to Paris. There she began to learn science and mathematics at the famous university of the Sorbonne. At first Marie could speak only a little French, but he worked hard and soon passed her examination. In Paris Marie met another scientist Pierre Curie, and in 1895 she married him.
In 1898 both the Curies decided to investigate the radioactive elements in pitchblende. The Austrians gave them a lot of pitchblende for their work, and the Curies began to experiment with it slowly and carefully. They worked hard for four years, and at last Marie obtained a very small piece of radioactive element—radium. It weighed only one tenth of a gramme, but it was pure radium and it shone with a wonderful light. The new element was valuable to science, but it was beautiful too.
