After forty-three years I have forgotten the name of the old lady, who was a   16   on the newspaper route in my hometown when I was a twelve-year-old boy. Yet it remains in my memory that she taught me a lesson in     17   that I shall never forget.

On a winter afternoon, my fellows and I were throwing stones onto the slanted (倾斜的) roof of the old lady’s house to observe how the stones    18    off the roof’s edge and shot out like missiles. I found a   19   smooth rock and threw it out, but it  20  straight not for the roof but for a small window of the old lady’s house.   21   the sound of broken glass, we knew we were in trouble. We ran faster than any of our   22    flew off her roof.

I was so   23   about getting caught that first night   24   I was not concerned about the old lady with the broken window in winter.    25  , a few days later I started to feel guilty for her misfortune. She    26   greeted me with a smile when I gave her the newspaper, but I was no longer able to act    27   in her presence.

I    28   my mind that I would save my newspaper delivery money, and in three weeks I had seven dollars. I put the money in an envelop with a    29   explaining that I was sorry for breaking her window and hope that the seven dollars would    30   the cost for repairing it.

I waited until it was     31     to avoid being seen, and put the letter I didn’t    32   into her yard. To my relief, I could have the   33  of, once again, looking straight into the old lady’s kind eyes.

The next day, I handed the old lady her newspaper. She thanked me and gave me a bag of cookies she had made herself.   34  eating cookies, I felt an envelope and pulled it out of the bag. After opening it, I was shocked. Inside were the seven dollars and a short note    35  , “I’m proud of you.”

Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could．Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas．And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere．Much of the CO₂ that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water．
Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself． "You don't build Mars," Mackay says．"You just warm it up and throw some seeds．" Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO₂, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow．Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession （系列） of ecosystems ?first bacteria and lichens （地衣）, which survive in Antarctica, later mosses （苔藓）, and after one thousand years or so, redwoods．Getting breathable oxygen levels out of those forests, though, could take thousands of years．
However, Mars is in no immediate danger．Some space scientists recently recommended going to the moon or an asteroid （小行星） first, and pointed out the space agency lacks the funds to go anywhere．It didn't estimate the cost of gardening a dead planet．
72．What is the most essential to make Mars fit for living?
A．Turn ice into flowing water．          B．Clean the dirty atmosphere．
C．Make the atmosphere more suitable．    D．Go to the moon or an asteroid first．

DOES the Yangtze River still have baiji（白鳍豚）, the graceful, grey dolphin with tiny eyes and a long narrow beak? Since November 6, a team of scientists from China, Switzerland, the United Kingdom, the United States, Germany and Japan have been searching for any sign of the freshwater dolphin on the middle and lower sections of the river. After six weeks, they came back empty-handed.

Wang Ding, of the Chinese Academy of Sciences, who is the head of the team, said he has seen a sharp decline in the baiji population over the past few decades. However, he is still unwilling to call the species extinct, and adds, “We will try every effort to save them as long as they are not found to be extinct.”

The baiji is shy and nearly blind and is one of the world’s oldest dolphin species. It dates back some 20 million years and is found only in the Yangtze. It's listed as one of the 12 most endangered animal species in the world.

Around 400 baiji were believed to be living in the Yangtze until the 1980s. 1 A 1997 survey spotted 13. Two years later their numbers were down to two.

The rapid disappearance of this dolphin over the past two decades coincided with the rapid expansion of economic development along the river. Research on some dead baiji collected in recent years showed that more than 90 per cent of the deaths were caused by human activities.

One reason is that over-fishing has cut the dolphin's food sources. Dams built along the river and neighbouring waterways have also kept them from swimming into and out of their habitats (居住地). Meanwhile, waste discharge (排放) has seriously polluted the river. And heavy river traffic has greatly reduced their living space.

The disappearance of the baiji would be the first instance of a large aquatic (水生的) mammal being driven to extinction since hunting killed off the monk seal around 1952.

1．Which of the following statements is true?

       A．The baiji is already extinct.

       B．Man is mainly responsible for the sharp decline in the number of baiji.

       C．There are about 12 baijis now in China.

       D．Human activities make the baiji almost blind.

2．What does the underlined sentence mean?

       A．People don’t find out the fact that the baiji is already extinct.

       B．We shouldn’t give up saving the baiji despite its limited number.

       C．Our effort is worthless if we can’t protect the baiji.

       D．Effort will lead to more population growth of the baiji.

3．Monk seal is talked about in the last paragraph in order to show        .

       A．baijis might be faced with the same threat as monk seals

       B．the monk seal is one of the large aquatic mammals

       C．mammals are more likely to be killed off

       D．the number of monk seals was very small

4．According to the passage, all the measures to help save baiji are mentioned except        .

       A．reducing the number of the ships traveling in the river

       B．building fewer dams along the river

       C．limiting and controlling the amount of fishing

       D．conducting more scientific research on the baiji

Andy was still travelling in Spain when he realized he had to eonfirm(确认) his flight home with the airline company. He was visiting Spain in order to   36  his Spanish. When he was speaking to people   37  he had no   38  understanding what they said.   39  , when he was speaking on the phone, he   40  had a problem. Andy   41  the airline. And the clerk confirmed that his plane was leaving at nine o’clock three days from that day. She   42 told Andy to be at the airport two hours   43  in order to check in his luggage and get a set.

Since he was   44  in three days, Andy didn’t   45 any time. He visited as many places as he could. He thought that it would probably be a while before he had enough money again.  He wished he could   46  and spend a year in Spain.

Too   47   , the final day arrived. Andy left early for the airport to arrive two hours before takeoff. He hated to  48 . He went to the clerk to    49  his ticket. The clerk looked at the ticket with   50 . “Why, sir, but your flight was at nine o’clock in the morning, and   51  it is eight in the evening. ”“But I confirmed my flight. ”  52  Andy. “Will I have to pay for another ticket?”

“No, sir. However, the next flight out will be three days from now. ”

Andy’s  53 of shock turned to one of  54   as he realized that now he could continue his   55  .
