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(重温) 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 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 had 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 (精神病学) at Harvard Medical School. "This could relieve(减缓) 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. 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’d want to wipe those memories out.” said Rebecca Dresser, a medical ethicist (伦理学家).
Some people fear that although the drug would first be used in only very serious cases, it would become more and more common.“People always have the ability to misuse science,” said Joseph LeDoux, a New York University memory researcher. “All we want to do is help people have better control of memories.”

Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses (床垫) and blankets).The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.

Our house was directly across the street from the clinic entrance of John Hopkins Hospital in Baltimore. We lived downstairs and rented the upstairs rooms to the patients at the clinic.
One evening as I was fixing supper, there was a knock at the door. I opened it to see a truly awful-looking man. He’s hardly taller than my eight-year-old son. “Good evening. I’ve come to see if you’ve a room. I came for a treatment this morning from the eastern shore, and there’s no bus till morning.” He told me he’d been hunting for a room since noon but with no success. “I guess it’s my face…I know it looks terrible, but my doctor says with a few more treatments…” For a moment I hesitated, but his next words convinced me: “I could sleep in this chair on the porch. My bus leaves early in the morning.”
I told him we would find him a bed. When I had finished the dishes, I talked with him. He told me he fished for a living to support his five children, and his wife, who was hopelessly crippled (残疾的) from a back injury. He didn’t tell it by way of complaint. Next morning, just before he left, as if asking a great favor, he said, “Could I come back and stay the next time?” He added, “Your children made me feel at home.”
On his next trip he arrived a little after seven in the morning. As a gift, he brought a big fish and the largest oysters (牡蛎) I had ever seen. I knew his bus left at 4:00 a.m. and I wondered what time he had to get up in order to do this for us.
In the years he came to stay overnight with us and there was never a time that he did not bring us vegetables from his garden. I know our family always will be grateful to have known him; from him we learned how to accept the bad without complaint when facing the misfortune.Why did the author agree to let the man spend the night in his house at last?

People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs (病菌) , a new study says. The energy waste is equivalent to the fuel use of a small country.
Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often “a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions.”
Carrico said, “It’s certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate.”
Carrico said that after a review of the scientific literature, her team found “no evidence that using hot water that a person could stand would have any benefit in killing bacteria.” Even water as cold as 40°F (4.4°C) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed（冲洗）and dried properly.
Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico’s team calculated a significant impact on the planet.
“Although the choice of water temperature during a single hand wash may appear unimportant, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually,” she said.
The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a “comfortable” temperature, which they noted may be warmer in cold months and cooler in hot ones. What’s the meaning of what Carrico told National Geographic in the second paragraph?
| A．People are more concerned about their health and begin to wash their hands. |
| B．It’s important for people to wash their hands to keep healthy. |
| C．Generally, people’s hand washing behaviors and perceptions are not correct. |
| D．People like washing their hands very much. |
The figures in the sixth paragraph are used to show that __________.
| A．using hot water to wash hands has a bad influence on our planet. |
| B．air pollution has become more and more serious. |
| C．using hot water to wash hands is a waste of energy. |
| D．people should pay more attention to the environment around us. |
This passage is organized in the pattern of __________.

Recently, the TV show “Where are we going, Dad?” produced by Hunan Satellite Television is a big hit /across nation. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the Daddy and cute kids triggered（触发）a lot of people’s emotional resonance（共鸣）. Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.
The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.
In the real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children’s education is also very low.
It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that “Where are we going, Dad?” shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go.
To raise a child in modern society, parents should ________.
| A．break down the barrier between children and teachers |
| B．balance well between family and career |
| C．play computer games with their children |
| D．keep their children at home to avoid socializing |
What does the underlined word “participation” probably mean?
| A．taking responsibility | B．understanding |
| C．taking part | D．keeping company |
What attitude towards modern family education does the author express in the second paragraph?
| A．Optimistic. | B．Indifferent. |
| C．Proud. | D．Worried. |
Which one is the best title of the passage?
| A．New problems in Modern Children’s Education |
| B．Modern Education is Important |
| C．Confusion Behind “Where are we going, dad?” |
| D．Nanny Daddy and Cute Kids |
