NASA is moving ahead with plans to put a long-armed Lander on Mars’ icy North Pole to search for clues for water and possible signs of life.
The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.
Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes existed in the ice.
Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.
True to its name, Phoenix rose from the ashes of previous missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction.
The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.

After giving a talk at a high school, I was asked to pay a visit to a special student. An illness had kept the boy home, but he had expressed an interest in meeting me. I was told it would mean a great deal to him, so I agreed.
During the nine-mile drive to his home, I found out something about Matthew. He had muscular dystrophy (肌肉萎缩症). When he was born, the doctor told his parents that he would not live to five, and then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal power lifter, and I knew about overcoming obstacles and going for my dreams.
I spent over an hour talking to Matthew. Never once did he complain or ask, “Why me?” He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He didn’t mention that his classmates had made fun of him because he was different. He just talked about his hopes for the future, and how one day he wanted to lift weights with me. When we had finished talking, I went to my briefcase and pulled out the first gold medal I had won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, “You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you.”
Last summer I received a letter from Matthew’s parents telling me that Matthew had passed away. They wanted me to have a letter he had written to me a few days before:
Dear Dick,
My mum said I should send you a thank-you letter for the picture you sent me. I also want to let you know that the doctors tell me that I don’t have long to live any more, but I still smile as much as I can.
I told you someday that I would go to the Olympics and win a gold medal, but I know now I will never get to do that. However, I know I’m a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you. Thank you for loving me.
Your friend,

Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毁灭的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip (啜饮) of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.What do most people think causes bad behavior?
| A．Being forced by others. | B．Enjoying their first experiences. |
| C．Not having enough will power. | D．Following the examples of their friends. |
The author mentions his experience in the third paragraph to prove ____.
| A．will power helps develop bad habits sometimes |
| B．drinking beer is harmful to the health of teenagers |
| C．self-control should be developed when one is young |
| D．everyone can be challenged by different temptations |
In the last paragraph, the author stresses that ____.
| A．without self-control, no one can succeed |
| B．applying self-control correctly is important |
| C．bad habits don’t always lead to bad results. |
| D．people can develop wisdom from bad behavior |
What would be the best title for the passage?
| A．My First Sip of Beer | B．Do You Have Will Power ? |
| C．Will Power Benefits Us | D．Dark Side of Self-control |
LONDON (Reuters)—New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities (怪异)，researchers said．
The findings give hope to some people with severe facial disfigurement and suggest the transplants could prove longlasting without major problems．Despite the tissue rejection in the first year after their transplants，neither men had psychological problems accepting their new faces and have been able to rejoin society，they reported．
Only three people have received face transplants．The world’s first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog．In 2007，her doctors reported that she had recovered slowly and steadily，overcoming two periods of rejection．
In 2006，Chinese doctors performed a face transplant on a 30yearold hit by a bear．While there were some complications with tissue rejection following the operation，two years later the man was doing well，his doctors said．“This case suggests that facial transplantation might be an option for restoring a severely disfigured face，and could enable patients to bring themselves back into society，” Shuzhong Guo and colleagues at Xijing Hospital in China wrote．
A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease，an illness that changes the shape of his face．“The man，who was not named，was given a new nose，mouth and chin in a 2007 operation．He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue，” his doctors said．
“Our case confirms that face transplantation is practical and effective for the correction of specific disfigurement，” Dr．Laurent Lantieri and colleagues at the HenriMondor hospital outside Paris wrote．What’s the main idea of this passage?
| A．Face transplants help regain confidence． | B．Face transplants can work． |
| C．Three people have received face transplants． | D．Disfigured people need face transplants． |
The underlined word “restoring” in Paragraph 4 means “________”．
| A．removing | B．recovering | C．repairing | D．rejecting |
What problem resulted from the facial operations?

A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃惊的) ways of cheating every day; some claim that certain accounts of cheating can be justified, but overall it can always be prevented.
Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.
There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the student could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students refrain(制止) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.
It may be difficult to accomplish, but cheating can be prevented. Teachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling(驱逐) a student, which will most likely hindertheir plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way to avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.
There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.Which is the best title of this passage?

Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.
Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that lifeexpectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country.
In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.
Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation.The underlined word “expectancy” in Paragraph 3 probably means “ ”
