As a teacher, I think all students were dear to me, especially Mark.

    Mark was very talkative, I had to1 him repeatedly that talking without2was not acceptable. Every time I had to correct him for misbehaving. “Thank you for correcting me, Sister!”3 I became accustomed to hearing it many times a day.

    Once my 4 was running out when Mark talked again, I5two pieces of tape(胶带) and made a big X with them over his mouth. When I 6 the tape, he still thanked me for correcting him.

    One Friday, I asked the students to 7the names of the other students on two pieces, leaving a8between each name, and then write down the 9 thing they should say about others.

    Then I10all the lists and gave each student his or her list. Soon the entire class was smiling. “I never knew that11anything to anyone!” “I didn't know12liked me so much!” Mark said, “Thank you for keeping me13 Sister.”

    Later Mark joined the army and was 14in Vietnam. After the funeral(葬礼), his father showed me something15 on Mark. It was pieces of notebook paper that had16 been taped and folded many times, on which were the good things that Mark's classmates had said about him. His mother said that he behaved better and better17my list.

    Mark's classmates told me that they kept their own lists in18 ways. Hearing this, I finally cried.

    Sometimes the19 things could mean the most to others. We forget when life will end. So20 the people you love and care about, before it is too late.

    Christmastime in the city brings forests of trees already cut and waiting to be sold. But some people like to drive to tree farms. Others wait for their trees to come to them. They order one from the pages of a catalog or on the Internet. Some say the easiest thing of all is to buy a man­made tree with Christmas lights already on it. No falling needles to have to clean up.

    The National Christmas Tree Association says 33,000,000 real trees were sold last year, compared to 9,000,000 man­made ones. Man­made trees generally cost more, but they can be reused. Most natural trees are cut up and recycled, but some people buy trees that can be planted.

    Most Christmas trees are now grown on farms instead of in forests. Twenty-one thousand tree farmers in the United States grow Christmas trees on more than 180,000 hectares. Oregon was the leading producer last year.

    Twenty-two percent of people who bought real trees last year chose them at a farm. Two percent of those people cut the trees themselves. The next most popular places were big stores like Walmart and Home Depot. Groups like the Boy Scouts also sell Christmas trees. But some people pay nothing for theirs. They steal it.

    Cornell University in Ithaca, New York, has many pretty evergreens. Some years ago, a university worker found a way to keep them there. A month before Christmas, workers treated them with “pink ugly mix”. It contains water and red food colour. The bright colour starts to disappear after about a month. It can take longer, however. Cornell decided not to use the mix this year, but the idea has spread.

    The First Americans

    There was a time long ago when a land bridge connected Asia and North America. The first settlers in North America crossed this land bridge from what is now Siberia to Alaska. The people who made this initial crossing were probably following the animals they used for food.

    Finally, the oceans rose and the land bridge between the continents disappeared. The settlers, who I shall call the “First Americans”， could not return to their homeland.

    For the next few thousand years, the First Americans moved south and east throughout North and South America. They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10,000 miles.

    In the far north, above the Arctic Circle, the First Americans became hunters of the ocean.In the summer, they gathered berries and other plants. In the winter, they stayed in lodges much of the time preparing for the next summer. It was a hard life, but they learned to survive in these terrible conditions.

    Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers. They began by living in caves that already existed in the cliffs.The dwellings they built in many ways resembled today's apartment buildings.

     They built a system of dams and canals so they could store and use water almost any time of the year. They were so successful that they could raise fruits and vegetables that were not found naturally in the desert.

A．They also discovered foods like corn and potatoes.

B．Along the way, they established many different civilizations.

C．They discovered how to add to the caves by building structures of wood and stone.

D．People living near each other tended to share similar environments and customs.

E．They built boats of animal skins and hunted or fished for their food.

F．They would have to survive in the New World they had discovered.

G．The First Americans of the Southwest learned to water the desert.

    As we all know, questioning can lead to (search) for an answer. If we are in the habit of raising doubts as towhat we are told is true, we can find the correct answer and learn more.

    Two years ago, our teacher (offer) us an answer to a difficult math problem in class. Although the answer seemed a little strange, nobody me doubted it. Thinking that his answer might be wrong, I(careful) analyzed the problem and tried to work out in a different way. Half an hour (late), I managed to find the correct answer. When I showed my answer to him, the teacher praised me for my (depend) thinking.

    From this experience, I have learned that questioning can serve as  bridge that helps us to seek the (true).

     “Plants were expected to get larger with increased carbon dioxide in atmosphere, but  changes in temperature, humidity and nutrient availability seem to trumped the benefits of  increased carbon dioxide，” said researchers from the National University of Singapore.

    45 percent of the species studied now reach smaller adult sizes than they did in the past. The  researchers pointed out that warmer temperatures and changing habitats, caused by climate  change, are possible reasons for shrinking creatures.

     “We do not yet know the mechanisms involved, or why some organism are getting smaller while others are unaffected，” the researchers said. “Until we understand more, we could be risking negative consequences that we can't yet quantify.”

    The change was big in cold­blooded animals. Only two decades of warmer temperatures were enough to make reptiles smaller. An increase of 1 degree centigrade caused nearly a 10 percent increase in metabolism (新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton, the base of the marine ecosystem.

    Warm­blooded animals weren't immune from the size change caused by climate change. Many birds are now smaller. Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records.

    This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a long time than the current climate change.

    The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate change will be shown in future.

    You've flown halfway around the world；you've sniffed out this place that nobody in Falongland or Thailand seems to have ever heard of；so what on earth is there to do here？You consider this question as you sink into an old wooden beach chair that holds you above the sand.

It was a long journey from Bangkok to Huaplee.By the time you found the bus station and got yourself sorted out，it took almost as long as the flight from Falongland.

    Huaplee is located just south of Hua Hin，about two hundred kilometres from Bangkok，down the west side of the Gulf of Thailand. Not many tourists find this place，and the ones that do wonder if finding it has been their purpose all along.

    There's an apparent laziness that surrounds you here.It's what this place offers，and it's free of charge.The small waves that tap the shoreline seem to slow everything down.You settle into your beach chair in preparation for a long rest.You sit there and watch the sea.

    It's early afternoon，so the cook comes out and asks what you'd like to eat this evening.Before long he's rushed off to the market to buy the ingredients for whatever it was that you ordered－every meal fresh and to order.No menu here.

    There is no poolside noise here but just that wonderfully warm，clear blue sea.There's no street noise.The only sounds are the murmurs of nature.

    For now you just count your blessings (福祉)，listing them in the sand with your toe (脚趾)．You don't have to worry about being late for work. You don't have to do anything.

    The beach to your right stretches off to the horizon (地平线)，slowly narrowing to nothingness only to reemerge again on your left，now steadily widening until it covers the chair beneath you.Sand to your left and sand to your right; it's unbroken，endless.No start，no end，just sand，sun，and peace.Step off it，and you re­enter the world of traffic，stress，work，and hurry.

    Normally you're the type who can't sit still for more than ten minutes，but you're on Huaplee Lazy Beach now and，in the right frame of mind，it stretches all the way around the world.

     “How could it take me so long to find it？” you wonder.

    There are two basic ways to see growth：one as a product，the other as a process.People have generally viewed personal growth as an external(外在的)result or a product that can easily be identified and measured.The worker who gets a rise，the student whose grades improve，the foreigner who learns a new language—all these examples of people who have measurable results to show for their efforts.

    By contrast(对照)，the process of personal growth is much more difficult to determine，since it is a journey and not the specific signposts or landmarks along the way.The process is not the road itself，but the attitudes，feelings people have，and their caution or courage，as they meet with new experiences and unexpected difficulties.In this process，the journey never really ends；there are always new ways to experience the world，new ideas to try，new challenges to accept.

    In order to grow，to travel new roads，people need to have a willingness to take risks，to face the unknown，and to accept the possibility that they may“fail”at first.How we see ourselves as we try a new way of being is necessary for our ability to grow.Do we see ourselves as quick and curious？If so，we tend to take more chances and be more open to unfamiliar experiences.Do we think we're shy and indecisive？Then our sense of fear can cause us to hesitate，to move slowly，and we think we are slow to adapt(适应)change or that we're not smart enough to deal with a new challenge.Then we are likely to take a more passive role or not try at all.

    These feelings of insecurity(不安全)and self­doubt are both unavoidable and necessary if we are to change and grow.If we protect ourselves too much，then we stop growing.We become trapped inside a shell of our own making.
