NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.

Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.

In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.

The research has caused a great deal of argument. Some think it is a bad idea, while others support it.

Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

"Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."

But those who are against the research say that changing memories is very dangerous because memories give us our identity (特质). They also help us all avoid the mistakes of the past.


"All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.

【推荐1】When I was 16years old and in foster care (非亲代养)in Tennessee,people told me I was unadoptable.But I desperately wanted a family.I sought the help of a judge,even the commissioner of the Department of Children's Services and was adopted just a week before my 18th birthday.

We have a lot to be grateful for and this holiday season .Let's not forget about the more than 415000 youth in foster care especially older youth.These youth are the most likely to get overlooked for adoption but they shouldn't be.They need and deserve a family just as much as young children do.Making an older youth a part of your family can bring just as much a joy as adopting a baby or a younger child-without all the diapers and potty training.

My adoption was life changing and probably the best thing that ever happened to me.I still remember the first gift my parents gave to me.It was a Mickey Mouse key chain with a key to their home.They told me that no matter what happened they would always love me and I'd always have a place to come home to.This is our 17th Thanksgiving together…

My first Thanksgiving with my family was a little overwhelming with lots of extended family including grandparents,aunts,uncles,and cousins.However,it's when I realized that I would never have to spend another holiday alone and that was truly an amazing feeling.

I was always eager to spend time with my little sister,Beth.She was six when I joined the family.My dad always says he knew we were really sisters,and I was no longer a guest in the house when Beth and I had our first fight.Today,she's one of my best friends,and I'm her biggest cheerleader.

There were also bittersweet Thanksgivings.One we spent in my mom's hospital room.It was there that she helped me plan my wedding but passed away three weeks before the ceremony,My dad walked me down the aisle,and my sister was my maid of hono,Because of our bond we were able to support each other through that challenging time and that's what family is for-the good and bad times.

It's nice having my dad and sister to share holidays and special occasions.But they're even more important when it comes to the little things like having someone to share my bad day with,celebrate my promotion at work,or help me think through a difficult decision.It's in these moments that I just can't imagine being alone in the world.

I'm so glad that I didn't listen to those people who said I was unadoptable,I'd never find a family,and that I was putting myself out there for rejection.It's a risk for older foster youth to consider adoption.It's an opportunity to be rejected once again But it's a risk they should take because life doesn't end at 18.It's really just beginning.

If you know someone who might consider adopting an older teen,please share my story--and have him or her think of my family.They didn't get to see my first steps or watch me be a pilgrim in my second grade Thanksgiving play.But they taught me so many things about life and were there to watch me walk across the stage when I graduated from college and law school and accompanied me to the White House last year as I was honored for my work helping foster youth.

I look forward to many more Thanksgivings with my family and I'm eternally thankful they chose me to be a part of their family.

文章大意:这是一篇说明文。文章主要分析了为什么人们总是在乘坐交通工具的时候睡着的原因。

【推荐2】Do you always fall asleep on bus journeys?

    1     I have been suffering from being unable to sleep for many years. Some nights when I can’t sleep, I’ll head to the coach where I can usually fall asleep within minutes. My friend also told me that sometimes he was stressed out by his work and he couldn’t sleep at night. But when he was traveling on the bus, he was able to sleep well. Since this happens regularly, I decided to find some answers.     2    

One popular view is about the white noise. It is a continuous sound like the hum of tires or the purring of the car. White noise masks (掩盖) distracting noise and is helpful for people who have trouble getting sleep.     3     When you’re riding a vehicle, white noise is continuously emitted (发出), making it easier for passengers to drift off to dreamland.

Another view as to why it’s easy to fall asleep in buses or trains is because of the rocking (摇晃) movement that’s similar to what comforted us when we were babies. However, it’s not the movement itself that leads to a better sleep.     4     If you were rocked to sleep as a baby, you’d have that association (联想) that when you experience a rocking motion, you go to sleep.

An increase in carbon dioxide (二氧化碳) in public transportation can be one reason, too.     5     Carbon dioxide increases when there are lots of people in a small space. This will lead to lack of oxygen (氧气), which will affect the brain’s performance and reduce activity in the cerebral cortex, making people sleepier.

A.Rather, it’s the link between rocking and sleeping.
B.Why do we sleep better on the coach than in our bed?
C.It may also help mothers settle babies with mild sleep problems.
D.Cars and other vehicles are a perfect environment that produces it.
E.Buses and trains get crowded every day with people going to and from work.
F.It seems to be much easier to fall asleep on a running bus than in the comfortable bed.
G.The running vehicle offers a comfortable rocking environment for those with sleep problems.

【推荐3】If you use social media to chase away loneliness, a new study suggests you’re going against the gain.

We may have heard a lot about the benefits of interacting with others online, but the findings of a study conducted by University of Pittsburgh School of Medicine scientists show a direct relationship between social media usage and feelings of isolation (隔绝). In short, the more time you spend on social media, the lonelier you may feel.

With increased interaction on a large number of apps that allow for endless virtual connectivity, loneliness seems like the last problem frequent social media users would face, but according to the leader of the study Brain Primack, it has the exact opposite effect.

“Mental health problems and social isolation are at widespread levels among young adults nowadays,” Primack said, “We are naturally social creature, but modem life tends to separate us instead of bringing us together. While it may seem that social media presents opportunities to fill the social void (空隙), I think this study suggests that it may not be the solution people were hoping for.”

Primack and his team examined the social media habits of 1,787 U.S. adults aged 19 to 32 via a questionnaire that asked about the time and frequency they spent on the most popular social media platforms. Eventually, they determined that young adults who are constantly logging into social media reported more feelings of isolation than those with less social media usage. Frequent exposure to unrealistic descriptions on social media instead of face-to-face social interactions may give people the impression that others are living happier, more connected lives, and this may users feel more socially isolated in comparison.

1. What does the underlined phrase “going against the grain” in Paragraph 1 mean?
A.Doing it all wrong.B.On the way to success.
C.Taking a risk.D.Making a difference.
2. How did Primack and his team conduct the study?
A.By providing explanations.B.By collecting data online.
C.By doing a survey.D.By describing their own experiences.
3. What can we learn from the study?
A.You will feel happier if you spend more time online.
B.Interaction online is not the solution to social isolation.
C.Virtual connectivity is best way to fill the social void.
D.Popular social media platforms can bring people together.
4. What does the text mainly tell us?
A.New study on social media usage has been published.
B.Face-to-face social interactions are on the way out.
C.Social media does users more harm than good.
D.Social media might make loneliness worse.
