    Since the sex of a sea turtle(海龟)is determined by the heat of sand hatching the eggs, scientists had suspected they might see slightly more females. Climate change, after all, has driven sea temperatures higher, which, in these creatures, favors female children. They found female sea turtles from Raine Island, the Pacific Ocean's largest and most important green sea turtle living area, now outnumber males by at least 116 to 1. "This is extreme," says turtle scientist Camryn Allen.

    Biologist Michael Jensen wanted to know if climate change had already changed turtles' sexes. By using genetic(基因的) tests, he'd figured out that he could follow turtles of all ages. Still, his research data would lack an important detail: sex. Only after a turtle matures is it possible to tell its sex from the outside -- mature males have slightly longer tails. By then turtles can be decades old, so scientists often use Iaparoscopy(腹腔镜检查),sending a thin tube into each animal, but that's not so practical if you're hoping to examine hundreds of creatures. Fortunately, at a turtle conference, he met Allen, and all she needed was a little blood.

    They compared their results with temperature data for nesting beaches. What worries them is that Raine Island has been producing almost female turtles for at least 20 years. This is no small thing. More than 200,000 turtles come to nest there. During high season, 18,000 turtles may settle in at once. "But what happens in 20 years when there are no more males coming up as adults? Are there enough to maintain the population?" says Allen. They also found cooler beaches in the south are still producing males, but that in the north, it's almost entirely females hatching. These findings clearly point to the fact that climate change is changing many aspects of wildlife biology.

    But how widespread is this phenomenon -- and what is the consequence?

(1)、How might the scientists feel if there were slightly more female turtles?
A、It's normal. B、It's unique. C、It's extreme. D、It's doubtful.
(2)、What is a scientist's conventional way to identify a turtle's sex?
A、Testing its blood. B、Doing genetic tests. C、Using laparoscopy. D、Watching its tail.
(3)、Why do the findings worry Jensen and Allen?
A、Too many females gather near Raine Island. B、Sea turtles may end up dying out. C、Turtle populations are in decline. D、Female turtles cause temperatures to rise.
(4)、What does the last paragraph imply?
A、People should stop the phenomenon. B、People have to test the consequence. C、Climate change has changed sea turtles' sexes. D、More work needs doing about the phenomenon.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries, like the UK or France, people find it easier to build up a lasting working relationship at restaurants or cafe rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion, instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values, however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well-known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half-dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else-there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

    What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. “In the sweat of the face shall you eat the bread.

    To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.

    They like using the Internet. They have lots of pocket money to spend.And they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy — games, CDs and clothing — are easily sold on the Web.

    But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parent's card. They want a service that allows them to spend money.

    That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate (刺激)online sales.

    In general, teenagers spend huge amounts: $153bn (billion) in the US last year and £20bn annually in the UK.Most teenagers have access to the Internet at home or at school — 88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online — mainly CDs and books.

    In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask “Why?” if you ask to spend some money online.

    One way to help teenagers change notes and coins into cyber cash is through prepaid cards such as Internet Cash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as£20 or $50 with a concealed (隐藏的) 14-digit number that can be used to load the cash into an online account.

    Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness(荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.

    Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warming. An avalanche(雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.

    But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.

We're often told "laughter is the best medicine".Laughter is ancient and instinctual,and a fundamental part of everyday life—something most of us enjoy naturally.There are comedy channels on TV,comedy festivals and our favorite funny friend who's sure to get our giggle on.

So why do we need laughter experts?Surely they're for people who can't laugh for whatever reason.However,while the ability to laugh is innate,the decision to activate and use it to its full ability is a choice.

When life gets stressful;illness creeps in;relationships are put to the test or we're struggling financially,there's rarely much to laugh about.So,we don't.Yet turning into the lighter,more humorous side of life,and activating one's "laughter self" is critical to mental health.Rather than waiting for something funny to happen or for life to be a bed of roses,we can transform our emotional state by tapping into our laughter and humor resources.This helps create distance between us and our pain and improve our moods and resilience(恢复力) to stress.It provides relief and release from some of the stress that has embedded in our bodies and minds,freeing ourselves to power forward,even a little.

Ironically,because laughter is an innate and largely unconscious behavior,it's rarely given much thought.As it's seldom thought about,it can't be that important.

Wrong.If laughing is a more complex behavior,my belief is people will pay greater honor to it,rather than something to laugh off.It's actually one of the most complicated things our bodies process.It is a vocal means of communication before language forms and the brain has fully developed.The vast majority of us maintain the ability to laugh until our final curtain falls,even amid declining cognitive function.

Turning toward the healing power of humor and laughter assists with personal and professional resilience,performance and overall well-being.No joke.
