NASA’s twin Mars rovers, Spirit and Opportunity, have been exploring the Red Planet since 2004. But a little more than a year ago, NASA lost contact with Spirit. The space agency has tried several ways to make contact with the rover, but Spirit has not sent back any signals.

Spirit landed on Mars on January 4, 2004. Three weeks later, Opportunity arrived. Soon after, the rovers went to the opposite side of Mars. Spirit’s original mission was only designed to last for three months, but Spirit has worked for more than five years doing additional missions. Both rovers have made important discoveries about ancient Mars. They have taken thousands of images and found evidence in the rocks of a water, warmer past in Mars’ history.

Spirit is solar-powered. It got stuck in a sand trap in April 2009, trapped deep into the soil and with its wheels turning around and around but not able to move forwards or backwards. Spirit had to agree that there is nothing that can be done to change the situation—it’s never going to move again. However, even if it is a not moving station, it can still study the planet’s atmosphere and deep interior.

NASA has been concentrating on trying to position its solar panels to get as much energy from the sun as possible, or to get the rover leaning in a manner that will allow the most amount of sunlight falling on its solar panels, in order to keep it alive during the coming winter months. Engineers have planned to rock the vehicle back and forth to acquire a more favorable position. However, no matter how many efforts have been made, Spirit still could not get out of the soft soil and could not lean itself toward the sun as the Martian winter approached. Without enough energy reaching its solar panels and with so little energy in its batteries, it went into hibernation, just like a polar bear, and has not communicated with Earth since March 22, 2010.

Whatever the future holds for Spirit, its mission has been an outstanding success. When it landed on the Red Planet in January 2004, no one was really sure how long it would continue working in the cold and dusty environment. As a matter of fact, three months was its original goal.

After so many fruitless efforts, NASA scientists are losing hope of ever reconnecting with Spirit, but they will give it one more try. Ground controllers are contacting Spirit over a range of frequencies and at different times during the day in case its internal clock stopped working and it lost track of time. They also are commanding the rover to turn on its backup radio transmitter in case the main one is dead.

If this final effort to connect isn’t successful, NASA will shift the focus to its twin robot, Opportunity, which is in a different part of Mars. Opportunity is still on the move and continues to travel freely to this day. It has traveled 16.6 miles so far, and is currently rolling towards another crater it has yet to explore.

NASA has spent more than $900 million on the project but shows no sign of giving up on these determined and hard-working robots. The rovers are, though, experiencing gradual wear and tear, the expected damage to something caused by using it repeatedly over a period of time. Even before Spirit got trapped, one of its wheels had failed. And NASA says it’s just a matter of time before both robots break down completely.

The way we do things round here

Some years ago, I was hired by an American bank. I received a letter from the head of the Personnel Department that started, "Dear John, I am quite pleased that you have decided to join us." That "quite" saddened me. I thought he was saying "we're kind of pleased you decided to join us although I wish we had hired someone else." Then I discovered that in American English "quite" sometimes means "very", while in British English it means "fairly".

So the first lesson about working in other countries is to learn the language and by that I don't just mean the words people speak. It is body language, dress, manners, ideas and so on. The way people do things highlights many of the differences we see between cultures（文化）．

Some of these differences may be only on the surface-dress, food and hours of work-while others may be deeper and take longer to deal with. Mostly, it is just a question of getting used to the differences and accepting them, like the climate（气候），while getting on with business.

Some of the differences may be an improvement. People are more polite; the service is better; you ask for something to be done and it happens without having to ask again. However, other differences can be troubling, like punctuality（准时）．If you invite people to a party at 7 o'clock your guests will consider it polite to turn up exactly on time in Germany, five minutes early in the

American Midwest, an hour early in Japan, 15 minutes afterwards in the UK, up to an hour afterwards in Italy and some time in the evening in Greece. I prefer not to use the word "late" because there is nothing wrong with the times people arrive. It is simply the accepted thing to do in their own country.

1.The author was unhappy as mentioned in paragraph 1 because he thought_____.

A. the American bank didn’t think much of him

B. the American bank might hire another person

C. it’s difficult to get used to American  culture.

D. it’s easy to misunderstanding Americans

2.The word “highlights”in paragraph 2 probably means_____

A. encourage B. helps to marrow

C. increase D. draws attention to

3. According to the author, what should we do with most cultural differences?

A. Ask the native people for help.    B. Understand and accept them.

C. Do things in our own way.       D. Do in-depth research.

4.. When invited to a party the people who are usually punctual are______.

A. Italians      B. Germans      C. Greeks       D. the British

In that case, there is nothing you can do _______ than wait.

A. more                                     B. other

C. better                                     D. any

When you think you’re sick, if you believe your doctor, and if he tell you that you are going                        feel better, you probably will．Here is an example．Mrs Green was unable to go to sleep at night and was tiring during the day．So she went to see her doctor she had been known for years．The doctor listened to her and gave her a very carefully examination．Then he said to her, “There is nothing serious, but I understand you don’t feel good．I’m going to give you some pills. You should take one after dinner and one before go to bed tonight．Call me tomorrow and tell me what you feel．”               

The next day, Mrs Green telephoned, saying , “Doctor, I have the first good night’s sleep in two months last night．” The doctor says, “It’s very good medicine．Just keep on taking them for a

week．” But in fact , the doctor just gave her some vitamin pills．
