    Smoggy weather has become common in China. But these days, air pollution levels in the north eastern city of Harbin surpassed the previous record levels.
The city was essentially shut down after PM2. 5, fine Particulate(微粒物) pollution that is considered hazardous(有害的) . reached levels of 1000 micrograms per cubic meter-40 times the safety level remended by the World Health Organization. Schools, motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10 meters.
Photos from Harbin showed residents covering their mouths with masks and scarves, and moving like ghostly shadows through the fog. Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible. .
Just days previously , the World Health Organization's International Agency for Research on Cancer (IARC)  classified air pollution as a carcinogen(致癌物) .  It stated that there  is  " sufficient evidence" that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer.  It's said that exposure has increased significantly particularly in " rapidly industrial countries with large populations".
"The air we breathe has become polluted with a mixture of cancer-causing substances" , Dr Kurt Straif , head of the IARC said in a press released.  "We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths. "
On the Chinese social media site Weibo , many users complained about the pollution and shared their concerns. References to "feed people with smog "have become popular on Weibo and there is a sarcastic play on the expression "serve the people" , as the two have a similar pronunciation.
"The impact of air pollution on people will be gradual. There won't be a sudden outbreak of symptoms, but normally three to five days after the smoggy weather occurs, there is a peak in the number of people seeing doctors, " Deng Ying,  a doctor at the Second Affiliated Hospital of Harbin Medical University was quoted as saying.

The 57­year­old，father­of­three，revealed on The Today Show that his children Jennifer and Rory were not allowed phones until their 13th birthday and his youngest daughter Phoebe is still waiting for one.
“We’ve chosen in our family that it’s 13 where you get a phone，” the self­made billionaire explained.

And in 2010 Mr Gates said that he intends to give most of his $61 billion fortune away rather than hand it down.“That wouldn’t be good either for my kids or society，” he said.
Also during the Today interview with host Matt Lauer，Mr Gates，who stepped down from Microsoft in 2008 to concentrate on philanthropy，said that helping others gives him the same excitement as creating software.
“What you really feel is what you’ve achieved.If a piece of software gets out there and lots of people love it—it lets them get their work done in better ways—that’s exciting，” he explained.

Besides entertainment and beautiful lanterns, another important part of the Lantern Festival, or Yuanxiao Festival is eating small dumpling balls made of glutinous rice flour. We call these balls Yuanxiao or Tangyuan. Obviously, they get the name from the festival itself. It is said that the custom of eating Yuanxiao originated during the Eastern Jin Dynasty in the fourth century, then became popular during the Tang and Song periods.
The fillings inside the dumplings or Yuansiao are either sweet or salty. Sweet fillings are made of sugar, Walnuts, sesame（芝麻）, osmanthus flowers(桂花), rose petals, sweetened tangerine（橘子）peel, bean paste, or jujube paste（棗子醬）. A single ingredient or any combination can be used as the filling . The salty variety is filled with minced meat（肉末兒）, vegetables or a mixture.
The way to make Yuanxiao also varies between northern and southern China. The usual method followed in southern provinces is to shape the dough of rice flour into balls, make a hole, insert the filling, then close the hole and smooth out the dumpling by rolling it between your hands. In North China, sweet or nutmeat stuffing is the usual ingredient. The fillings are pressed into hardened cores, dipped lightly in water and rolled in a flat basket containing dry glutinous rice flour. A layer of the flour sticks to the filling, which is then again dipped in water and rolled a second time in the rice flour. And so it goes, like rolling a snowball, until the dumpling is the desired size.
The custom of eating Yuanxiao dumplings remains. This tradition encourages both old and new stores to promote their Yuanxiao products. They all try their best to improve the taste and quality of the dumplings to attract more customers.
小題1:Which of the following is NOT true?
A．The custom of eating Yuanxiao dates back to the fourth century.
B．Sugar, rose petals and minced meat are all fillings of Yuanxiao.
C．Sweet Yuanxiao are usually made in southern China.
D．People in northern China usually make Yuanxiao by rolling like a snowball.
小題2:Which country does the Lantern Festival come from?
A．ChinaB．South KoreaC．Jin DynastyD．Tang and Song periods.
小題3:Choose the right order of making Tangyuan in southern provinces.
① make a hole and insert the filling 
② roll the dough between your hands 
③ shape the dough of rice flour into balls  
④ close the hole  
⑤ prepare some rice flour
A．⑤③②①④B．③⑤①②④C．③①④②⑤D．⑤③①④②
小題4:What is the best title of this passage?
A．The Lantern FestivalB．The ingredients of Yuanxiao
C．The difference between Yuanxiao and Tangyuan.D．China’s traditional food—Yuanxiao.
小題5:Why do we eat Yuanxiao today?
A．Because it’s a tradition.
B．Because it’s a tasty food.
C．Because we love our country.

One afternoon last week, I saw three tearful children from my son’s school being comforted by teachers. That morning, my 11-year-old had stomach pains, retching（干嘔）into a bowl. Talking to other mothers later, I heard about other children with stomachache or difficult sleeping the night before.
What caused so much pain? Sports day. Sports day might be necessary at a highly-competitive independent school, but not at a village primary school. For the children who can fly like the wind, sports day cause no problem. For those who are overweight or just not good at sport, it is nightmare（噩夢）. Even for those who enjoy running but fall halfway down the track in front of the entire school and their parents, it can prove a disease.
Why do we put our children through this annual suffering? Some may say competition is character building; or it’s taking part, not winning, that’s important; or that’s a tradition of school life. I just felt great pity for those children in tears or in pain.
Team games at the end of sports day produced some close races, wild enthusiasm, lots of shouting — and were fun to watch. More importantly, the children who were not so fast or quick at passing the ball were hidden a little from everyone’s eyes. Some of them also had the thrill of being on the winning side.
I wish that sports day could be abandoned and replaced with some other less competitive event. Perhaps an afternoon of team games, with a few races for those who want them, would be less stressful for the children and a lot more fun to watch.
小題1:What can we learn about the author’s son from Paragraph 1?
A．He talked with some mothers.
B．He comforted his classmates.
C．He had difficulty in sleeping.
D． He suffered from stomachache.
小題2:Sports day is still an annul event in this school probably because __________.
A．this is an independent school
B．it is a tradition of the school
C．it helps children lose weight
D．children enjoy watching sports
小題3:What does the author think about team games?
A．They should include more stressful races.
B．They are acceptable to different children.
C．They should be abandoned at primary school.
D．They are less fun for those who love running.
小題4:What is the author’s attitude towards sports day?
A．Critical.B．Neutral.C．Positive.D．Ambiguous.

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren (少植被的) snow-covered terrain (地形). So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs (模糊), then is obscured (遮蔽), and the result is total, even though temporary, snow-blindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.
小題1:To prevent headaches, watering eyes and blindness caused by the glare from snow, dark
glasses are _________.
A．indispensable and essentialB．usefulC．ineffectiveD．a(chǎn)vailable
小題2:When the eyes are sore tears are produced to _________.
A．balance the pain B．treat snow-blindness
C．clear the visionD．loosen the muscles
小題3:Snow-blindness may be avoided by _________.
A．concentrating on the solid white terrain
B．searching for something to look at in snow-covered terrain
C．providing the eyes with something to focus on
D．covering the eyeballs with more fluid
小題4:The scouts shake snow from evergreen bushes in order to _________.
A．prevent the men behind losing their way
B．beautify the landscape of the terrain
C．warm themselves in the severe cold
D．give the men behind something to see
小題5:A suitable title for this passage would be _________.
A．nature's cure for snow-blindness
B．snow-blindness and how to overcome it
C．soldiers marching in the snow
D．snow vision and its effect on eyesight
