In today’s congratulatory phone call to the team behind NASA's Mars Curiosity rover（火星车）, President Barack Obama made sure that if the mission discovers Martians, he'll be one of the first to know.
"If in fact you do make contact with Martians, please let me know right away," Obama said during the call, "I've got a lot of things on my plate, but I expect that that will go to the top of the list. Even if they're just microbes(微生物), it will be pretty exciting."
Obama also said he was impressed by the attention that's been paid to flight director Bobak Ferdowsi, the "Mohawk Guy" whose star-spangled haircut and warmhearted behavior during Curiosity's Aug. 5 landing won him Internet fame.
"I, in the past, thought about getting a Mohawk myself," Obama joked. "But my team keeps on discouraging me. And now that he's received marriage proposals and thousands of new Twitter followers, I think I'm going to go back to my team and see if it makes sense."
The congratulatory phone call is a tradition for the White House. But it was clear that Obama particularly enjoyed congratulating the scientists and engineers behind the amazingly successful landing of NASA's newest Mars exploration.
He also said the achievement reflected the American spirit, and he gave his personal promise to protect these critical investments in science and technology.
"This is the kind of thing that inspires kids across the country," he said. "They’re telling their moms and dads they want to be part of a Mars mission, maybe even the first person to walk on Mars. And that kind of inspiration is the byproduct of work of the sort that you guys have done."
The Curiosity rover's $2.5 billion mission focuses on studying billions of years' worth of geology on Mars and determining whether the planet was ever potentially suitable for people to live in. The mission is not specifically designed to explore life, even on the range of microbes, but it could point the way for future life-exploration experiments.

My mind went blank when I saw the gun pointing against the car window as we pulled out of the garage. This can’t be happening to me. Then I felt the gun, cold, against my head, and I heard my friend Jeremy saying, “What do you want? Take my wallet,” but at the time I thought of nothing.
I remember being a little annoyed when the gunman pulled me from the car by the hair. I remember the walk to the house --- Jeremy, me, the two men with two guns. I remember the fear and anger in the gunmen’s voices because Jeremy was being slow, and I remember wondering why he was being slow. I did not realize that Jeremy had thrown the keys into the bush. But I remember that sound of the gun hitting Jeremy’s head and the feeling as the man who had hold of my hair released me. And I remember the split second when I realized he was looking at Jeremy, and I remember wondering how far I could run before he pulled the trigger. But I was already running, and upon reaching the car across the street, I didn’t crouch(蹲伏) behind it but screamed instead.
I remember thinking there was something ridiculous and illogical about screaming “Help, help!” at eight o’clock on a Tuesday evening in December and changing my plea(恳求) to the more specific “Help, let me in, please let me in!” But the houses were cold, closed, unfriendly, and I ran on until I heard Jeremy’s screams behind me announcing that our attackers had fled.
The neighbors who had not opened their doors to us came out with baseball bats and helped Jeremy find his glasses and keys. In a group they were very brave. We waited for the police to come until someone said to someone else that the noodles were getting cold, and I said politely, “Please go and eat. We’re O.K.”
I was happy to see them go. They had been talking of stricter sentences for criminals, of bringing back the death penalty(处罚) and how the President is going to clean up the country. I was thinking, they could be saying all of this over my dead body, and I still feel that stiffer sentences wouldn’t change a thing. In a rush all the anger I should have felt for my attackers was directed against these contented people standing in front of their warm, comfortable homes talking about all the guns they were going to buy. What good would guns have been to Jeremy and me?
People all over the neighborhood had called to report our screams, and the police turned out in force twenty minutes later. They were ill-tempered about what was, to them, much trouble about nothing. After all, Jeremy was hardly hurt, and we were hopeless when it came to describing the gunmen. “Typical,” said one policeman when we couldn’t even agree on how tall the men were. Both of us were able to describe the guns in horrifying detail, but the two policemen who stayed to make the report didn’t think that would be much help.
The policemen were matter-of-fact about the whole thing. The thin one said, “That was a stupid thing to do, throwing away the keys. When a man has a gun against your head you do what you’re told.” Jeremy looked properly embarrassed.
Then the fat policeman came up and the thin one went to look around the outside of the house. “That was the best thing you could have done, throwing away the keys,” he said. “If you had gone into the house with them…” His voice became weaker. “They would have hurt her” --- he twisted his head toward me – “and killed you both.” Jeremy looked happier. “Look,” said the fat policeman kindly, “there’s no right or wrong in the situation. There’s just luck.”
All that sleepless night I replayed the moment those black gloves came up to the car window. How long did the whole thing last? Three minutes, five, eight? No matter how many hours of my life I may spend reliving it, I know there is no way to prepare for the next time --- no intelligent response to a gun. The fat cop was right. There’s only luck. The next time I might end up dead.
And I’m sure there will be a next time. It can happen anywhere, anytime, to anyone. Security is an illusion(幻觉); there is no safety in locks or in guns. Guns make some people feel safe and some people feel strong, but they’re fooling themselves.
【小题1】When the writer saw the gun pointing against the car window, ______.
| A．she felt very annoyed | B．she lost consciousness |
| C．she felt very much nervous | D．she lost the power of thinking |
| A．Jeremy’s fighting | B．The author’s screaming |

| B．she did not want to become an object of pity |
| C．she was angered by their being late to come to her help |
| D．she wanted to be left alone with Jeremy to get over the shock |
| A．the author was not hurt and gave a false alarm |
| B．they thought it was a case of little importance |
| C．the author and Jeremy could not tell the police anything |
| D．the gunmen had already fled when they arrived on the scene |
| A．neighbors are not helpful in moments of difficulty |
| B．the police are not reliable when one is in trouble |

University of Maryland student Ben Simon and his friends couldn’t stand to see good food thrown out on their campus.“We basically noticed that some of the extra food from the dining hall was going to waste at the end of the day.And we met with the dining services and asked them whether it would be okay if instead of throwing out the food we would donate it.And they were on board，” he said.
So 18 months ago，the students began what they call the Food Recovery Network.Each night，volunteers would show up at a campus dining hall to pick up leftovers and deliver them to area shelters and food banks.So far，they have donated more than 23 000 kilos of food that would otherwise have been thrown out.
Nationwide，$165 billion worth of food is wasted each year，according to the National Resources Defense Council.Spokesman Bob Keefe says that is about 40% of the country’s entire food production.“If we can reduce our waste in this country by 15%，we can feed 25 million hungry Americans.That is a huge benefit.That is what programs like this Food Recovery Network are doing，” he said.
Christian Life Center is one of the beneficiaries (受益者) of the students’ efforts.Ben Slye，the senior pastor (牧师)，said，“It has been just amazing to see these students take their own time，their own vehicles and own gas money and be able to make an effort like this.Each week we are able with this food probably to feed over hundred people.”
The University of Maryland’s Food Recovery Network now has 200 volunteers and the program has expanded to 18 schools across the country.“I want to grow 18 chapters to a thousand chapters within five years.And once we get to the Food Recovery Nation being at every college campus in America，we want to expand to restaurants and farms.” said Simon.
The volunteers are committed to making that happen.

LONDON, Feb. 18，2014 （Xinhua News agency） —Britain will send experts to East China's Shanghai to learn from the city's experience in maths teaching in an attempt to raise the teaching standards.
British Education Minister Elizabeth Truss is to lead a delegation of experts on a fact-finding mission to Shanghai's schools next week to see how children there have become the best in the world at maths, to get a first-hand look at maths classes and teaching methods there, and particularly to investigate why the performance of almost all children in Shanghai is high, regardless of gender or income.
Britain was last year placed 50th out of 148 countries and regions in the World Economic Forum's competitiveness ranking in quality of maths and science education. Two years ago, Shanghai topped the 2012 international PISA tables for maths, while England was ranked in 26th place. The top five were all in Southeast Asia, with 15-year-olds in Shanghai judged to be three years ahead of their peers in maths.
The education department said: "England's performance in maths has lagged behind while other countries have improved and overtaken us, including Poland and Germany." Actually, it is the latest step in the government's drive to raise standards in maths, looking at what has made schools in the far East the most successful in the world in teaching the subject.
"Shanghai is the top-performing part of the world for maths—their children are streets ahead. Shanghai and Singapore have teaching practices and a positive mind that make the difference. They have a belief that diligence makes up for lack of ability," Truss said. "Our new curriculum has borrowed from theirs because we know it works—early learning of key arithmetic, and a focus on times tables and long division（长除法）, for instance."
She was determined to change the situation as performance in maths is weakening the country's skills base and threatening the productivity and growth. The government is emphasizing maths because of the importance of good grades in the subject to young people competing for good jobs in a global labor market and to the economy more generally.
An education and skills survey released by the Confederation of British Industry last year showed that 30 percent of employers reported dissatisfaction with the standard of school and college leavers' numeracy. More than two-thirds of employers said they wanted both maths and science promoted more in schools.

The United Nations climate talks in Doha, Qatar, continued into their second week, Wednesday, as delegates from nearly 200 countries struggle to craft a replacement for the Kyoto Protocol, the global agreement on climate change that expires at the end of this month.
The negotiations are deadlocked （陷入僵局）over demands by poorer nations for financial help in coping with climate change.
United Nations Secretary General Ban Ki-moon called on delegates at the United Nations Conference on Climate Change to speed up their work on an agreement to address a warming planet.
“Let us be under no illusion（幻想）, this is a crisis, a threat to us all, our economies, our security and the well-being of our children and those who will come after," he said. "No one is immune to climate change, rich or poor.”
Delegates from nearly 200 countries --- rich and poor --- are in Doha to extend the Kyoto Protocol, the 1997 global climate change agreement that expires （到期）at the end of this month, and to begin to forge a new agreement to replace it.
Two issues block the way forward. Developing countries are demanding that industrialized nations fulfill their pledges(保证)under Kyoto to reduce their climate-changing industrial emissions of carbon dioxide and other greenhouse gases, and to put new, larger emission curbs on the table.
The developing nations, led by China, are also insisting that rich nations provide more aid to poorer countries to help them cope with the effects of climate change, including rising sea levels and more violent storms.
In Doha Wednesday, Tim Gore, a climate change policy advisor for Oxfam International, a confederation of groups working on social justice issues, applauded efforts by England, Germany and Sweden to increase their climate aid and expects other nations to follow.
“Those announcements are truly welcome. And they shine a spotlight on those that have remained silent: the U.S., Canada, Japan, even Australia," Gore said. "But we need to be very clear as well that those types of announcements made in press conferences can be no substitute for clear commitments in the text that poor countries have come here to negotiate.”
【小题1】What’s the main idea of the passage?
| A．China plays an important role in The United Nations climate talks in Doha, Qatar. |
| B．The United Nations climate talks in Doha, Qatar, continued into their second week, Wednesday. |
| C．Developing countries want rich nations to pay for climate change. |
| D．Ban Ki-moon called on delegates at the United Nations Conference on Climate Change to speed up their work on an agreement to address a warming planet. |
| A．Climate change will do harm to all the countries in the world. |
| B．There is no hope to deal with the problem. |
| C．Illusion（幻想）is a crisis, a threat to us all. |
| D．Ban Ki-moon called on delegates to cope with a warming planet. |
| A．put aside | B．deal with | C．call off | D．work out |
| A．Climate change includes rising sea levels and more violent storms. |
| B．All the industrialized nations will carry out their promises under Kyoto to reduce their climate-changing industrial emissions of carbon dioxide and other greenhouse gases, and to put new, larger emission curbs on the table. |
| C．Tim Gore thought highly of the efforts by England, Germany and Sweden to increase their climate aid and expects other nations to follow. |
| D．The U.S., Canada, Japan, even Australia didn’t make announcements to be responsible for the climate changes. |

A team of British surgeons has carried out Gaza’s（加沙）first organ transplants for a long-term plan to train local medical staff to perform the operations.
Two patients underwent kidney（肾脏）transplants at the Shifa, Gaza’s biggest public hospital. The operations were conducted a fortnight ago by a volunteer medical team from the Royal Liverpool hospital.
Ziad Matouk, 42, was born with one kidney and was diagnosed with renal failure（肾衰竭）several years ago. Matouk, whose wife donated one of her kidneys, hopes to return to his job within six months. The couple had sought a transplant in Cairo, but were rejected as unsuitable at a state hospital and could not afford the fee at a private hospital. “We were desperate,” said Matouk.
The UK-Gaza link-up began about a year ago after Abdelkader Hammad, a doctor at the Royal Liverpool hospital, was contacted by an anaesthetist（麻醉师）at the Shifa, who outlined the difficulties the Gaza hospital was facing with dialysis（透析）. The Shifa is forced to rely on generators because of power cuts; spare parts for its ageing dialysis machines have been difficult to import; and supplies of consumables are often scarce. After an exploratory trip last April, Hammad---whose family is Palestinian---and three colleagues from Liverpool arrived in Gaza via Egypt last month, bringing specialist equipment. Two patients were selected for surgery. The first, Mohammed Duhair, 42, received a kidney donated by his younger brother in a six-hour operation. Two days later, Matouk received a transplant after his wife, Nadia, 36, was found to be a good match. The surgeon was carried out by the British team, assisted by doctors and nurses from the Shifa. “We are very satisfied with the results,” said Sobbi Skaik, head of surgery at the Gaza hospital.
Skaik hopes that Gaza medical teams will eventually carry out kidney transplants independently, and that other organ transplants may follow. The Shifa is working with the Gaza ministry of health on a plan to train its doctors, surgeons, nursing staff and laboratory technicians in transplant surgery at the Royal Liverpool. “Funding is a problem,” said Hammad. “In the meantime we’ll go back as volunteers to Gaza for the next couple of years to do more transplants.” The Liverpool team’s next visit is scheduled for May.
【小题1】What effect does Gaza’s first organ transplants hopes to get?
| A．Helping poor Gaza people to regain health to make more money. |
| B．Releasing Gaza hospitals’ pressure of lack of professional doctors. |
| C．Assisting the Royal Liverpool hospital in perfecting their operations. |
| D．Calling for international attention at Gaza’s poor medical service. |
| A．Because he couldn’t afford the fee at a public hospital. |
| B．Because the hospital didn’t accept dangerous patients. |
| C．Because they couldn’t find a matched organ. |
| D．Because his condition was untreatable. |
| A．A UK doctor contacted Gaza hospital. |
| B．The Shifa imported medical machines from UK. |
| C．Ziad Matouk’s condition seemed to get worse. |
| D．A Shifa doctor turned to Royal Liverpool hospital for help. |
| A．They had an exploratory trip in Egypt last April. |
| B．They carried out surgeries to test Gaza’s medical equipment. |
| C．They carried out two transplant surgeries in Gaza. |
| D．They sought assistance from the hospital of the Shifa. |
