[2017·河北邯郸高三一模]
Chinese people are almost twice as optimistic about the world as those from other countries，while the British are the fifth most pessimistic(悲观的)，according to a recent survey.
YouGov surveyed more than 18,000 people in 17 countries，and found that 41 percent of Internet users in China say the world is getting better.The country's sunny attitude is nearly double the next most optimistic country，Indonesia，with 23 percent and four times the global average of 10 percent.
While it's said in most places the chances of getting killed by another human，life expectancy，poverty，and the rule of law have all improved significantly over the past 200 years,65 percent of adults in Britain disagree.An analysis of more than 10,000 British people last year found that believing the world is getting better depends significantly on being young，educated and middle class.
When it comes to GDP per capita(人均国内生产总值)and optimism about the world，research shows there seems to be little relationship.The United States has more than 31 percent more GDP per capita than the United Kingdom.However，the two countries are equally pessimistic，with 65 percent of the surveyed saying the world is getting worse.Meanwhile，Australia，which is the second most pessimistic country only next to France，has almost 20 times more wealth per person than the second most optimistic，Indonesia.Only three percent of the surveyed in Australia believe things are looking up.
Research suggests the huge gap between China and the rest of the world when it comes to the fate of the planet shows something special.The country's pure rate of growth，a prioritization (优先)of health and quality of food are all contributing factors to this belief in a bright future.
1．According to the survey，the global average of optimistic people is________. A．10 percent B．23 percent C．41 percent
D．65 percent
2．Who tend to hold bright attitudes to the world in Britain? A．The old. C．The rich.
B．The poor. D．The educated.
3．What can we infer from the fourth paragraph?
A．Wealth does not necessarily mean optimism. B．Economic growth has nothing to do with optimism. C．Economic decline is a result of pessimistic attitudes. D．People in developed countries are more optimistic. 4．Which might be the reason for Chinese optimism? A．China is a developing country. B．Chinese people are the healthiest. C．Chinese population grows rapidly. D．China puts people's well-being first.
答案：[解题导语]YouGov的一项调查显示，在17个参与调查的国家中，中国人的乐观指数最高。
1．A 解析：细节理解题。根据文章第二段最后一句．..four times the global average of 10 percent.可知，调查显示，全球乐观指数平均值为10%。故选A项。
2．D 解析：细节理解题。根据第三段最后一句An analysis of more than 10,000 British people last year found that believing the world is getting better depends significantly on being young，educated and middle class.可知，英国的年轻人、受过教育的人以及中产阶级持有较积极的态度。故选D项。
3．A 解析：推理判断题。根据第四段第一句When it comes to GDP per capita and optimism about the world，research shows there seems to be little relationship.可知，人均国内生产总值似乎和乐观态度关系不大，而人均国内生产总值代表着财富，也就是说，财富与乐观态度没有必然联系，即财富并不一定代表态度乐观。故选A项。
4．D 解析：细节理解题。根据文章第五段最后一句The country's pure rate of growth，a prioritization(优先) of health and quality of food are all contributing factors to this belief in a bright future.可知，中国经济的快速增长、优先考虑健康状况和食品安全等都是中国人乐观积极的原因。故选D项。
Ⅱ.阅读填空
[2017·陕西宝鸡高三检测]
When we think of the word “positive”，most of us probably think of “happy”．__1__ There are many ways to be more positive in your life，even when you're experiencing sadness，anger or challenges.
__2__ Accept the things about yourself that you can't change.Accept yourself for who you are right now，just as you are.You can then feel free to develop that self into the most positive self you can be!
Make goals.Goals give us a more positive outlook on life.Research has shown that
setting a goal can make you feel immediately more confident and hopeful，even if you don't achieve the goal right away.__3__
Use your body.Your body and your mind are intimately connected.Smile.Research suggests that when you smile－whether you “feel” happy or not－your brain elevates your mood.What you wear also has an impact on how you think and perform.__4__ Find clothes that make you feel good about yourself and wear them，no matter what society tries to say about it.
Get some exercise.When you exercise，your body releases powerful endorphins，the body's natural “feel-good” chemicals.__5__ Studies have also shown that regular，moderate exercise increases your feelings of calmness and well-being.
A.Happiness is the only true measure of personal success. B．Accept what you are.
C．However，happiness isn't the only type of positivity. D．Setting goals that are personally meaningful to you. E．Dress in a way that delights yourself. F．The color you wear could affect how you feel.
G．Exercise can help fight feelings of anxiety and depression.
答案：[解题导语]积极乐观并不等同于快乐，生活中有许多方法可以让你有积极乐观的心态，即使你感到悲痛、愤怒或者面临挑战，依然可以乐观面对。
1．C 解析：上文提到，一说到积极乐观就会想起快乐，而下文则说明即使感到悲伤、愤怒或面临挑战也可以有积极乐观的心态，上下文有转折。C项(但是，快乐不是积极乐观的唯一方式。)符合语境。故选C项。
2．B 解析：设空处为段落主题句。根据设空后的Accept the things about yourself... Accept yourself for who you are right now...可知，本段强调“要接受自己”，故选B项。
3．D 解析：本段主题是“设定目标”。设空前提到设定目标可以给自己一个更积极的生活态度、使你更有信心等，因此D项“设定对你自己有意义的目标。”符合语境。
4．E 解析：本段主题是“利用你的身体”。设空前提到你的穿着影响你的想法和表现，E项(穿上让你开心的衣服。)与此相符。故选E项。
5．G 解析：本段主题是“参加锻炼”。设空后提到，有研究表明有规律且适度的锻炼能够让人感到平静和幸福。由此可知，设空处应该是指锻炼的好处。G项(锻炼能够帮助抵抗焦虑感和抑郁感。)符合语境。
