The mom had died when the rescuers found her after the terrible earthquake. She was covered by a destroyed house. Through gaps(缝隙) of those ruins, the rescuers could see her last posture(姿势). It was something like an ancient person who was kowtowing(叩头), but it just looked strange because she was out of shape by pressure.
The rescuers confirmed(证明) her death by touching her through the gaps of the ruins. They shouted at the ruins again and again, knocked the bricks using various tools, but no reply inside.
Then the rescuing team went to the next building. Suddenly the leader ran back, calling "Come here." He came to the body, put his hands under the woman, feeling and touching, then shouted loudly and gladly, "There is someone, a baby, still living."
Through some efforts, rescuers cleaned up the ruins which blocked her. Under her body lay her baby, who was covered by a small red quilt (棉被)．He was about 3 or 4 months old. Since well protected by his mother's body, he was safe. He was in a deep sleep when the rescuer carried him out, and his lovely and peaceful face warmed everyone around him. The doctor, along with the rescuing team, took the baby out of the quilt to check if the baby was all right, and he found there was a mobile phone in the quilt. The doctor looked at the screen; a written message was already there: "My dear baby, if you could live, doesn’t forget how much I love you." As a doctor, he experienced much of this type of separation；but at this moment, he cried. The mobile phone was passed, and every person who saw this message shed (流出) tears.When the rescuers found the mom, she________.
| A．was using her mobile phone to ask for help |
| B．begged the rescuers to save her baby first |

OK, I admit it: emoticons (表情符号) are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications.
Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast (抨击) the use of emoticons as “infantile (幼稚的) just like the people who use them” He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent (明显的) from the comment that goes before the emoticon,” he argues.
In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’ s an emoticon gene.”
It’s an interesting opinion, but it is not shared by all.
In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (融入) something beyond language. They reach to our need to be with and communicate with people.
All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking.
Friends, however, send me messages and e-mails full of emoticons. I have no problem with this. I don’t regard any of my friends as lazy or immature (不成熟的). It’s just a question of individuality. :)According to the article, emoticons are popular because ______.
| A．most of them look funny |

PEOPLE who have had a painful experience may wish they could wipe the memory from their minds. Researchers at Johns Hopkins University, US, say that this may someday be possible.
A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain’s fear center to cut memories forever.
Previous research had already shown that a special behavior therapy (治疗) could cut painful memories. But relapse (复发) was possible because the memory hadn’t necessarily disappeared.
By looking at that process, Richard Huganir and Roger Clem, two researchers from Johns Hopkins University, discovered a “window of vulnerability (脆弱的窗口)” when proteins are created. The proteins help signals travel within the brain as painful memories are made. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories.
Researchers used mice to find the window, but think the process would be the same in humans. They used electric shocks to make the mice fear a certain sound. The sound triggered (触发) the creation of the proteins, called calcium-permeable (钙通透性) AMPARS, which formed for a day or two in the fear centers of the mice’s brains.
The researchers are working on ways to reopen the window by recalling (唤醒) the painful memory and using drugs to remove the protein. They published their report online last month in Science Express.
Their research has drawn interest and concern from experts in mental healthcare.
Kate Farinholt, a mental health expert with the National Alliance on Mental Illness, Maryland, US, said many people suffering from a painful event might benefit from erasing a memory. “Erasing a memory and then everything bad built on that is an amazing idea, and I can see all sorts of potential ,” she said.
But there are a lot of unanswered questions, too.
“Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone’s life,” Farinholt said. “And is it best to do that, considering that people grow and learn from their experiences?”What have researchers at Johns Hopkins University found recently?
| A．A new drug to erase painful memories from human brains. |
| B．A special behavior therapy to erase painful memories. |
| C．Removing certain proteins from the brain can wipe painful memories. |
| D．Erasing memory damages a patient’s brain functions. |
What makes it possible to erase painful memories according to Paragraph 4?
| A．The way the brain cells are created. |
| B．The unstable character of the proteins in the brain. |
| C．The strength of the signals the proteins send. |
| D．The drugs that can stop the formation of memories. |
Which of the following shows the stages of the process done on mice?
a. removal of fear proteins b. making mice fear a certain sound
c. fear proteins created in mice brains d. making mice recall painful memories
| A．a-b-c-d | B．d-a-c-b | C．b-c-d-a | D．c-b-d-a |
What is Kate Farinholt’s opinion of the research?
| A．People may lose the chance to learn from their bad experiences. |
| B．The research will be a great breakthrough in treating painful memories. |
| C．People could suffer long-term memory loss. |
| D．People could forget happy memories as well. |
While all my classmates seem to be crazy about a one-way ticket to Mars, I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return? Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory┅. For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. Donal Trollop, Canada
There are already too many people on the Earth. I think that something before the end of the century, there will be a human colony on Mars. It will happen when people finally realize that two-way trips to the red planet Mars are unnecessary. Most of the danger of space flight is in the launches and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement in another world. Enough supplies can be sent on ahead, and every two years more supplies and more people will be sent to the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other planets in the outer space. Paul Davies, USAThe main purpose of Steve Minear’s writing is_________. .

Federal regulators(调整者) Wednesday approved a plan to create a nationwide emergence alert (警报) system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation’s emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.
"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages, according to the rules.
The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies, or so-called Amber Alerts.
The service could be in place by 2010.What is the purpose of the approved plan?
| A．To warn people of emergencies via messages. |
| B．To popularize the use of cell phones. |
| C．To estimate the monthly number of messages. |
| D．To promote the wireless industry. |
The improvement to the present system is in the charge of ____.
| A．CTIA | B．the Warning Alert and Response Network |
| C．FCC | D．federal regulators |
The carriers’ participation in the system is determined by _____.
| A．the US federal government | B．mobile phone users |
| C．the carriers themselves | D．the law of the United States |
Which of the following would be the best title for the text?
| A．Cell Phone Alerts Protecting Students | B．Cell Phone Alerts by Wireless Industry |
| C．Cell Phone Alerts of National Disasters | D．Cell Phone Alerts Coming Soon |
Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
But that doesn’t have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.What is the real cause of the potentials water crisis.
| A．Only half of the world’s water can be used. |
| B．The world population is increasing faster and faster. |
| C．Half of the world’s water resources have been seriously polluted. |
| D．Humanity has not placed enough value on water resources. |
As is indicated in the passage, the water problem _________ .
| A．is already serious in certain parts of the world. |
| B．has been exaggerated by some experts in the field |
| C．poses a challenge to the technology of building reservoirs(水库) |
| D．is underestimated by government organizations at different levels |
According to the author, the water price should _______ .
| A．be reduced to the minimum | B．stimulate domestic demand |
| C．go with its real value | D．take into account the occurrences of droughts |
In order to raise the efficiency of the water supply, measures should be taken to ______ .
| A．guarantee full protection of the environment |
| B．centralize the management of water resources |
| C．increase the sense of responsibility of agencies at all levels |
| D．encourage local and regional water resources |
