【题目】 How about forgetting bad memories?

Can we forget bad memories? Someone might tell you that time is the only “cure”. But this might be not true.

Researchers at Canada's McGill University have tested a pill that can help you forget bad memories. They tested it on 60 people and found it to be useful.

All 60 people had experienced painful romantic relationships and wanted to forget them. In the study, they were asked to write about these bad memories. Then, they took a pill that is usually used to treat high blood pressure (血压). They then recalled their bad memories by reading what they wrote earlier. In the end, they talked about their feelings, saying that they were finally able to forget their bad experiences.

Dr. Alain Brunet, who led the study, believes that the pill can ease(缓解)the pain that bad memories bring. People can take it after bad things happen to them.

How did the pill do this? In fact, your memories change all the time. They’re like papers on your computer. Every time you recall and "open” the papers, you might happen to make some changes and "save" them. Researchers believe that the pill can stop something in the brain from "re-saving" these memories. This means some details of the memory are lost.

However, there are some ethical (伦理的)worries about this treatment. Some people might use it to forget things that they should be learning from, such as when they did a crime.

A11 of us can think of bad events in our lives that were terrible at the time but make us who we are. They also help us all avoid the mistakes of the past. I'm not sure we want to erase those memories, said Rebecca Dresser, a medical ethicist.

How do we form memories?

The part of our brain known as the hippocampus (海马体)is important for forming new memories. Scientists found it after studying a patient named Henry Molaison in the 1950s. After Molaison's hippocampus got hurt during an operation, he couldn't store new memories. But he could remember memories from before the operation. This means long-term memories are stored outside the hippocampus. Scientists believe they are stored in the neocortex(新皮质),which controls attention and planning.

2The pill tested on people can ________.

D.The pill should be used to reduce people's sufferings from bad memories.

B.taking the pill will be harmful to people's physical health

C.the pill has been produced and used by the public America

D.medical workers are still unsure about the influence of the pill

【题目】 Is there a connection between music and language? According to recent studies, the answer is yes: 1Here, we look at two examples

A recent study by researcher Kraus shows that playing a musical instrument can improve a person's hearing ability.2The people in the first group were musicians, while those in the second group had no musical training. The musicians were able to hear the talking person more clearly.

3Think about violinists in an orchestra ( 管弦乐团). When the violinists play with the group, they hear their own instrument and many others, too. But the violinists must listen closely to what they are playing, and pay no attention to the other sounds. In this way, musicians are able to focus on certain sounds, even in a room with lots of noise.

Schlaug, a doctor at Harvard Medical School, works with stroke (中风) patients. Because of their illness, these people cannot say their names, addresses, or other information normally. However, they can still sing.4Why does this work? Schlaug isn't sure. Music seems to make different parts of the brain work, including the damaged (损坏的) parts. This might help patients to use that part of the brain again.

Music improves concentration ( 注意力), memory, listening skills, and our overall language abilities. It can even help sick people get better. Playing an instrument or singing can help us do better in school and keep our brain sharp (敏锐的) as we get older. Music is not only enjoyable, it's also good for us in many other ways.

A.Musicians hear better because they learn to pay attention to certain sounds.

B.Music helps people solve some hearing problems.

C.Music improves certain language abilities in the brain.

D.Schlaug was surprised to find that singing words helped his patients to speak.

E.In his study two groups of people listened to a person talking in a noisy room.
