Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming． Countless recent reports from the world’s leading scientific bodies have said the same thing． For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity．”
The idea that humans could change the planet’s climate may be counter-intuitive（与直觉不符的）, but the basic science is well understood． Each year, human activity causes billions of tons of greenhouse gases to be released（释放）into the atmosphere． As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanke
t．
Of course, the planet’s climate has always been changing thanks to “natural” factors（因素） such as changes in solar or volcanic（火山的）activity, or cycles relating the Earth’s going around the sun． According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes．
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question． As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without． That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty． In most scientists’ opinion, the global warming is mainly caused by ．
| A．solar activity | B．volcanic activity |
| C．the Earth’s going around the sun | D．human activity |
The text is developed by ．
| A．giving typical examples | B．foll owing the order of space |
| C．analysing a theory and arguing it | D．comparing and finding differences |
The underline word “identical” means ．
| A．totally different | B．exactly the same |
| C．extremely important | D．relatively independent |
Four simple keys to transform your life
The power of choice.
Every one of us makes countless choices every day. Every choice we make has an impact on our lives. Even insignificant choices can affect what we experience and how we feel. When hunger strikes, we can reach for a healthy, nutritious snack, or we can choose the sugar high of junk food. The more important the decision, the greater its effect. For instance, how do I act towards that person who treated me badly? Do I generally choose to be passive, or do I actively set clear intentions and create what I want in my life? Every choice we make, however big or small, affects us in some way.
How do you make choices?
If you are interested in living a richer, fuller life, there is a foundation upon which you can base all of your decisions which can make life better not only for you, but also for those around you. This foundation is to choose based on what’s best for all. Imagine a world where every parent, spouse(配偶), friend, teacher, businessperson, and politician truly did their best to choose what’s best for all involved in every decision they made. We would certainly live in a more caring, supportive world.
It’s the intention.
“But how do I know what is really best?” you might ask. The answer is simple. It doesn’t matter. What matters is not the choice you make, but rather the intention behind your choice. What matters is that whatever decision you make, you are clear in your intention of choosing based on what’s best for all. If it later turns out that you made what appears to have been a bad choice, there’s no need for guilt. Knowing that you did your best to choose with a sincere desire for what’s best for all, your conscience stays clear and open. This then allows you to more easily learn from your mistakes, and to live with a clear heart and mind.
What’s best for me, too!
Choosing what’s best does not mean you have to always sacrifice yourself for other. An overly(过度的) exhausted mother can lose her temper easily. Some time off for this mother might seem selfish, yet in the long run, it can help her to be a better mother to her children. So as we move through each day of our lives, let us remember to include ourselves as we do our best to choose what’s best for all.According to the passage, which of the following statements is NOT true?
| A．Every one of us makes countless choices every day. |
| B．Every choice, however big or small, has an influence on us. |
| C．People act differently towards the person who treated them badly. |
| D．People tend to reach for a junk snack when hunger strikes. |
How should we make choices?
| A．To be interested in a richer, fuller life. |
| B．To make life better for ourselves. |
| C．To base our choices on what’s best for all. |
| D．To imagine a world where everyone did their best. |
According to the author, what is really best?
| A．The choice you make. | B．The intention behind your choice. |
| C．The mistake you learn from. | D．The consequence of your choice. |
To choose what is best for us, we’d better ________.
| A．try to be selfish all the time | B．sacrifice ourselves for others |
| C．set aside some time for ourselves | D．control our temper before children |
These days, many passers-by always spot a beggar on the Jiaochangkou Street in Yuzhong District of Chongqing in southwest China.
The beggar’s name is Xia Haibo, and he was born in Meihe Village, Tianmen City of Hubei Province. Being 25 years old, he is quite a special beggar in some ways — he doesn’t beg on his knees, as other beggars do when begging. Rather, he often stands in the crowded street, either reading a book or thinking about something carefully. He also started a blog on the Internet which has been clicked more than 500,000 times. He likes reading — he has read many classical Chinese poems. He has kept writing and recently, he has planned to publish his writings.
In 1998, Xia entered Tianmen Middle School as the best student in his town. However, a year before he took the college entrance examination, he came down with a high fever and was later diagnosed (诊断) as having rheumatoid arthritis (类风湿性关节炎). In order to treat his disease, his father borrowed 60,000 yuan from relatives and friends. However, with this money, he didn’t recover from the disease. He did not want to become a burden (负担) to his family any more. So in July, 2006, he left his hometown and went to Wuhan to make a living by begging.
Begging has become a job to Xia now. However, he doesn’t plan to go on living like this. “By July 24, 2008, when I have been begging for two years, I will stop my begging life. I promise,” he said.
It is his plan that by using the money he “earns”, he will rent a small shop in his hometown and keep on writing in his spare time.
Right now, he is trying to finish a book of his own. The book, called Love Is With Me, tells about the people who helped him during his begging life. The underlined word “spot” in the first paragraph is closest in meaning to “______”.
| A．forgive | B．record | C．beat | D．notice |
When did Xia Haibo get the serious illness?
| A．In 1998. | B．In 2001. | C．In 2000. | D．In 2006. |

| B．He writes Chinese poems for those who like poems. |
| C．He reads or thinks while standing in the street. |
| D．He teaches people how to surf the Internet. |

| D．He will keep writing while running a small business. |
The life-long benefits of teaching children how to take care of their money make it well worth the effort. Children who are not taught these lessons pay the consequences for a life time. Some parents don’t teach children about money because they think they shouldn’t talk about money with children, don’t have the time, or think they don’t have enough money. Parents should take the time to teach children about money regardless of their income and should start when children are young.
Most people have strong feelings and opinions about money, based on childhood experiences and the values and beliefs of their families. Most often, these experiences, values, and beliefs are different for each parent. Parents should talk about these feelings and opinions and establish an unchanging approach（方式） to teaching children about money. This is important for the healthy development of children.
Here are some tips that parents can keep in mind as they begin teaching their children to manage money:
★ Guide and advise your children how to spend their money, rather than tell them what they can and cannot do.
★ Encourage and praise children rather than criticize their actions.
★ Allow children to learn by mistakes and by successes.
★ Be consistent（前后一致的） while taking children’s differences into consideration.
★ Include all family members in money management discussions, decision making, and activities that are suitable for their age. As children get older include them in discussions of limits and consequences.
★ Expect all family members to do some everyday chores based on their abilities without being paid.
★ Express your desire to have things you can’t afford. Children need to know that parents say “no” to themselves, too. It is _____ for parents to teach their children about money management in their childhood.
| A．easy | B．useless | C．too early | D．beneficial |
15-year-old Harry isn’t good at managing his money. His mother is advised to _____.
| A．explain to him how to manage his money better |
| B．pay him more money to deal with his chores |
| C．praise him for what he has done |
| D．allow him to buy what he wants |
When parents discuss how to manage the family finances, they should _____.
| A．include their children in the discussion |
| B．express their desire to have some valuable things |
| C．pay more attention to their children’s differences |
| D．try to meet their older children’s needs first |
Dear Editor,
I have just returned home after studying for a year in Germany. But it seems that my parents don’t understand me now. They expect me to be the same person I was before I went abroad, but I’m not! Why can’t they let me be myself?
Jimmy
Hi, Jimmy,
As far as I know, people who have lived abroad often find that the adjustment （调整） to returning home is more difficult than their adjustment to living in a foreign culture. Why? We expect to have some problems when we go to a new place, speak a different language and learn the rules of a different culture ... But home? ... we know that place!
Your parents expect that the same person who boarded the airplane one year ago will be returning. Especially if they have never been abroad themselves, your parents probably won’t understand the changes that living abroad can cause in a person. On the other hand, you may have maintained (保持) an ideal mental image of your loved ones while abroad, an image that is broken into pieces when you return.
Remember you have been living a different lifestyle in your host country, and you have probably become very independent while staying there alone. Now that you’re home, you will be expected to conform （顺应） again to the lifestyle of your family. As a result, you may be upset about your parents’ involvement in your life.
Communication is the key to overcoming this problem. Tell your parents how you are feeling. Share with them information about cultural re-entry（重归）, and ask them to be patient. This does not mean that you have to forget your experience and give up everything you’ve learned! Learn to find a balance between the old and new, just as you did when first adjusting to your host country’s culture.What is Jimmy’s main purpose in writing the letter?
| A．To criticize his parents. |
| B．To ask for advice about his studies. |
| C．To complain about his parents. |
| D．To ask for help. |
What does the editor think of Jimmy’s problem?
| A．It’s unusual. | B．It’s normal. | C．It’s serious. | D．It’s interesting. |
The editor thinks that both Jimmy and his parents ______.
| A．have changed in the past year |
| B．have unrealistic expectations of each other |
| C．need to behave like they did before |
| D．need to find a balance between the good and bad |
The author suggests that ______ would help solve Jimmy’s problem.
| A．patience and trust |
| B．patience and politeness |
| C．better communication between family members |
| D．a deeper understanding of the host country’s culture |
Fourteen is not an age at which you try to earn millions of dollars. But for Bangalore boy, Suhas Gopinath, it was.
One day in August, 1999, Suhas, studying at the Air Force School in Hebbal, was surfing the Net at a cyber cafe. He happened to hit an MSN source code （源码）. That made him decide to learn more about HTML （超文本标记语言） and to design and set up his own website under the address of a US-based company, Network Solutions.
He kept updating his website, posting interesting things on it. This impressed Network Solutions and they invited him to attend a class on Web design and development.
