17.Years ago,I lived in a building in a large city.The next building only was a few feet away from mine.They was a woman lived there,and I had never met her,yet I could see she sat by her window each afternoon,sewing or reading.
After several months had gone by,I began to notice that her window was dirty.Everything was unclear through the dirty window.I would say to myself."I wonder why that woman doesn't wash her window.It really looks terrible."
One bright morning I decided to clean my flat,including washing the window on the inside.

18.Smog in Europe and North America could be more than 25times more deadly than the average air pollution found in Chinese cities,a new study suggests.In the largest ever study of its kind in the developing world,researchers tested the effects of air pollution on the health of people in 272 cities in China.
They found average annual exposure to fine particles,known as PM2.5,in those cities was more than five times higher than the level recommended by the World Health Organization (WHO),according to a paper in the American Journal of Respiratory and Critical Care Medicine.
However they also discovered that it was much less likely to increase the death rate than PM2.5in Europe and North America.
The researchers,led by Dr Maigeng Zhou,of the Chinese Centre for Disease Control and Prevention,suggested this was because China is affected by large amountsof natural dust blown by the wind from arid areas,while most pollution in the West comes from industry.
They found that for every increase of 10micrograms of air pollution in a cubic meter of air,the mortality rate increased by 0.22percent,discounting deaths from accidents.
Professor Frank Kelly,an expert in environmental health at King's College London,who was not involved in the study but has studied air pollution in China,told The Independent:"Those relative risks areconsiderably less than those seen in Europe and the US.For mortality(死亡率)in Europe we are working on a six percent increase per 10micrograms."That suggests air pollution in Europe is about 27times more toxic than average air pollution in China.
However,Professor Kelly said cities like Beijing,Shanghai and Hong Kong were likely to suffer from Western-style air pollution."The natural dust component there is not of the magnitude that it would dwarf the coal,biomass and fossil fuel signals,"he said,"That may be true in certain cities whose pollution is not dominated by local power generation or major traffic congestion."
Natural dust particles can cause physical damage to the lungs and trigger an asthma attack.Particles of carbon produced when fossil fuels are burned can lead to similar problems but they are also coated with toxic heavy metals,chemicals and volatile organic compounds.These are able to pass from the lungs into the blood stream where it is thought they cause further damage to the body.
Areeba Hamid,an air pollution campaigner with environmental group Greenpeace,said:"Poisonous air causes damage to people's health wherever in the world they live.We now know fumes from diesel(柴油機(jī)) vehicles area lot more poisonous than car companies claimed and this is a big cause of air pollution in Europe and North America.These companies have a lot to answer for,but so far they've managed to avoid any real accountability."
The study of cities in China found the average annual expose to PM2.5 was 56 micrograms per cubic meter,compared to the WHO guideline limit for safe air quality of 10micrograms.
People who were older than 75,had less education or who lived in hotter places were more likely to die.It is thought people in warmer cities were more likely to spend time outside or leave their windows open,thereby breathing more polluted air,the researchers said.They also speculated that less well educated people might have poorer access to health care or experience poorer environmental health conditions.

62.Why PM2.5 in China is less deadly than that in Europe and North America?B
A.China is free from any pollution about PM2.5.
B.Pollutants affecting China mainly come from arid areas.
C.Fewer people died from PM 2.5 in China than those in Europe and North America.
D.Europe and North America are polluted by natural dust.
63.What does the underlined part in Para 7 refer to?C
A.The average mortality rate.
B.The higher mortality rate.
C.The lower mortality rate.
D.The normal mortality rate.
64.What's the real cause of air pollution in Europe and North America according to Areeba Hamid?A
A.Fumes from diesel vehicles are much more poisonous.
B.The environmental agencis can't take on responsibilities.
C.The technology doesn't meet the standards.
D.Car companies can't evaluate the results.

B.illustrate smog in Europe and North America is quite serious.

20.First celebrated in 2013,the International Day of Happiness at the beginning of spring was established by the United Nations (UN) to remind us that"the pursuit of happiness is a fundamental human goal."
Setting aside a day to appreciate things that we take for granted-good health,family,and friends-was first suggested by the tiny South Asian country of Bhutan.It also came up with the idea of establishing the Gross National Happiness (GNH) Index (指數(shù)) in the 1970's.Bhutan,which has an annual per capita income of about $ 2,300,or 21 percent of the world's average,believes that material wealth,measured by the Gross Domestic Product (CDP) Index,is not a meaningful measurement of human happiness.
What can you do to celebrate the festival besides cracking a big smile?
•Give or receive a (free) hug
Seek out a sibling,parent,or friend,and make their day by giving them a warm hug.
•Take the"Happy Acts"challenge
It is the brainchild of the"Live Happy"magazine.It encourages people to perform a random good deed and post it on the magazine's social media sites or tweet about it at Happy Acts.The actions can be as simple as sharing a fun photo or calling a grandparent.
•Treat yourself
Sometimes all it takes to make one happy is a little indulgence (放縱).So grab a cup of cocoa or your favorite tub of ice cream and snuggle up (依偎) with a blanket and good book!
•Start a conversation
With the popularity of the Internet,we tend to spend more time looking at our screens than the person in front of us.Tuck your computers or smart phones away for one evening and spend time with your parents.You might be surprised at the joy it will bring them and you.
Finally,don't forget to love yourself for who you are and be happy every single day!International Day of Happiness is a reminder that joy is all around us-you just have to reach out and grab it!
 
24.The International Day of Happiness probably falls onC.
A.September 10
B.July 24

D.December 1
25.What do you learn about Bhutan?C
A.It is situated to the east of Asia in location.

C.It is one of the poorest countries in the world.
