Poets,songwriters and left—wing politicians hate the idea,but for decades,opinion—poll evidence has been clear: money buys happiness and the richer you are,the more likely you are to express satisfaction with your life.Until now,a survey of 43 countries published on October 30th by the Pew Research Centre shows that people in emerging markets are within a whisker of(一步之遥)expressing the same level of satisfaction as people in rich countries.It is in line with the standard view of happiness and income seen so far.
According to the survey,in 2007,57%of respondents in rich countries regarded themselves as happy;in emerging markets the share was 33%; in poor countries only 16%—a classic expression of the standard view. But in 2017, 54% of rich—country respondents counted themselves as happy,whereas in emerging markets the percentage jumped to 51%.
The sharp increase happened thanks to huge improvements in countries such as Indonesia (+35)and Pakistan(+22).In 12 of the 24 emerging markets,half or more people rate their life satisfaction in the top of the ladder.
This is not to say the link between income and satisfaction has been snapped. Poor countries still lag behind:only a quarter of the people there count themselves as happy—half the level of the other two groups.There is also a clear link between happiness and income growth.China's GDP rose at an annual average rate of 10% in 2007—2017 and its happiness level rose 26 points.
Within countries,richer people express more satisfaction than their poorer neighbors.The study divided respondents into categories with higher and lower incomes and fewer and more household goods.In every country in every group, richer folk with more goods expressed higher levels of happiness.So at a personal level,money does buy happiness.And if you ask people about different aspects of their lives—health,family life,religion,standard of living—it turns out that satisfaction with living standards still has the biggest influence on happiness.
1.What's the standard view of happiness and income?
A. Income is not closely related to happiness.
B. Happiness does not depend on how much you earn.
C. The higher your income is, the more likely you will feel satisfied.
D. The more you are satisfied, the more you can earn every month.
2.What contributed to the increase of happiness in emerging markets?
A. Their rapid development. B. Investment in emerging markets.
C. Economic downturn. D. More cooperation with rich countries.
3.What's the purpose of the writer by mentioning China's GDP?
A. To prove that China's GDP growth led to the happiness of people in Asia.
B. To remind readers of the progress that China has made.
C. To express the author's concern about the development of emerging markets.
D. To show that there is a link between happiness and income growth.
4.What is the author's attitude to the standard view of happiness and income?
A. Disappointed. B. Skeptical
C. Supportive. D. Indifferent.
When an ice cube melts, it creates a puddle (水坑). When an ice sheet (冰盖)melts, it raises sea levels. It sounds simple, but scientists have debated for decades whether both the Antarctic and Greenland ice sheets actually were shrinking, and how much that melting contributed to rising sea levels.
Now, a new study has provided the best evidence of how the polar ice sheets are responding to our warming world. In the study, an international team of scientists looked at 20 years of' data in the ice sheets collected by 10 satellite missions. The team's conclusion: The Greenland and Antarctic ice sheets both are losing ice overall. The researchers also found that between 1992 and 2011, melt water from those shrinking ice sheets caused sea levels to rise by about 11 millimeters.
Over the 19 years studied, the Greenland ice sheet lost 2.7 trillion metric tons of ice. The Antarctic ice sheet also shrank by about l.3 trillion metric tons. Previously, some scientists disagreed whether the Antarctic sheet, the largest mass of ice in the world, was shrinking or growing or neither.
While the Earth is warming overall, the effect of climate change varies from region to region. Over the last 15 years, for example, scientists have something disagreed over how climate change has affected the polar ice sheets. Many studies found that the sheets lost a lot of ice and that not enough snow fell on the sheets to compensate for the loss. But other studies found that the loss of ice was balanced by the gain in snowfall.
Richard Alley, a glacier scientist at Penn State University, said that many of those studies looked at different areas, and over different time periods. In addition, the studies didn't all use the satellite data in the same way. Those differences made, it difficult to compare the results.
The data in the new study matched time periods and areas. The study also combined measurements from kinds of satellites.
1.Why does the author use a common-sense phenomenon as the beginning?
A.To present the reason for ice sheet melting.
B.To show us the result of a scientific experiment.
C.To give a simple example to introduce the topic.

B.People are suffering from climate change.
C.Rising sea levels makes people live in danger.
D.Shrinking ice has nothing to do with sea levels.
This all started a few months ago, when I had a dull pain in the back of my mouth, around where one of my wisdom teeth was supposed to be coming in. I thought it was a pain that I could live with for a while.
However, during the next few weeks, the pain became more intense, spreading to my teeth, gums and jaw. I was told I had seven wisdom teeth.
Yes, you read that correctly, seven — three more than a normal person. My first reaction when I heard was to laugh. It’s just my luck. My mouth wanted to do more work than it had to.
Focusing on the positive, one of the great things about having extra teeth is watching people’s reactions when they find out. So far, I haven’t grown tired of repeating myself.
The extra teeth are also a good excuse for me being tongue-tied. I can now blame it on my overcrowded mouth rather than my slow brain.
Of course, with wisdom teeth come the intellect jokes. My parents say my intelligence comes from my extra teeth and not my hard work. My friends agree that once the teeth are pulled, my brain will be that of a 5-year-old.
I’ve also thought about how I might profit from this. If only I still believed in the tooth fairy, I could make a lot of cash. Maybe I could sell my extras to someone in need. Advertisement: Seven teeth for sale, unused, in almost perfect condition.
Don’t be fooled by my jokes. I am worried about having surgery. I’m also going to be sad to see the Lucky Seven go. I’ve developed quite an attachment to them over the past two days. Once they’re removed, I’ll just be normal again, and who wants that?
1.When the author found that she had three more wisdom teeth than a normal person, she ________.

A.persuade the author not to remove her wisdom teeth

D.let the author know why she is often tongue-tied
3.When the author brought up the idea of tooth fairy, she ________.
A.thought she could rely on it to make a living
B.had already made up her mind to make money
C.believed that her wisdom teeth were in perfect condition
