    9．Hu Li's heart sank due to the color of the air．Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze（炭灰色的阴霾）．The 39-year-old businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen．It gave her husband a cough and left her seven-year-old daughter housebound（足不出户）．"My husband as well as I is working here，so we have no choice，"she said．"But if we had a choice，we'd like to escape from Beijing．"
    The extended heavy pollution over the last month，which caused punishment in return for a day last week-called the"airpocalypse"by internet users-has largely changed the way that Chinese think about the country's air．On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization （WHO）．Flights were cancelled．Roads were closed．One hospital in east Beijing reported they had treated more than 900 children for breathing issues．Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area．
    The smog's（烟雾） most threatening aspect is its high concentration（浓度） of PM 2.5-particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development．The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia．
    32．Which conclusion can we draw from the first paragraph？C
    A．Hu Li is living in Beijing．
    B．Hu Li traveled to Tianjin for business．
    C．The haze is harmful to people．
    D．The pollution is the worst in Beijing's history．
    33．The haze affected people mainly inB．
    A．the way they traveled
    B．the opinion about national air
    C．the way they lived their life
    D．the life style of internet
    34．From the passage we know high concentration of PM 2.5D．
    A．can lead to choke
    B．can cause heart cancer
    C．will damage children's development
    D．will damage people's organ
    35．What's the best title for the passage？B
    A．Hu Li's attitudes to Beijing's haze
    B．The damages of Beijing's haze
    C．WHO suggests improving Beijing's air
    D．What caused air pollution in Beijing．

    6．I was sure that I was to be killed．I became terribly nervous．I fumbled （摸索） in my pockets to see if there were any cigarettes，which had escaped their search．I found one and because of my shaking hands，I could barely get it to my lips．But I had no matches，they had taken those．I looked through the bars at the guard．He did not make eye contact with me．I called out to him"Have you got a light？"He looked at me，shrugged and came over to light my cigarette．As he came close and lit the match，his eyes unconsciously locked with mine．At that moment，I smiled．I don't know why I did that．Perhaps it was nervousness，perhaps it was because，when you get very close，one to another，it is very hard not to smile．In any case，I smiled．In that instant，it was as though a spark jumped across the gap between our two hearts，our two human souls．I know he didn't want to，but my smile leaped through the bars and caused a smile on his lips，too．He lit my cigarette but staye d near，looking at me directly in the eyes and continuing to smile．
    I kept smiling at him，now thinking of him as a person and not just a guard．"Do you have kids？"he asked．"Yes，here，here．"I took out my wallet and nervously fumbled for the pictures of my family．He，too，took out the pictures of his family and began to talk about his plans and hopes for them．My eyes filled with tears．I said that I feared that I'd never see my family again，never have the chance to see them grow up．Tears came to his eyes，too．Suddenly，without another word，he unlocked my cell and silently led me out．Out of the prison，quietly and by back routes，out of the town．There，at the edge of town，he released me．And without another word，he turned back toward the town．

    13．San Francisco has its cable cars．Seattle has its Space needle．And，Longview has its squirrel（松鼠） bridge．The bridge，which has attracted international attention，is now a local landmark．
    The Nutty Narrows Bridge was built in 1963 by a local builder，Amos Peters，to give squirrels a way to cross the busy road without getting flattened by passing cars．
    The original bridge was built over Olympia Way on the west edge of the library grounds．Before the bridge was built，squirrels had to avoid traffic to and from the Park Plaza office building where office staff put out a nutty feast for the squirrels．Many times，Peters and others who worked in and near Park Plaza witnessed squirrels being run over．
    One day Peters found a dead squirrel with a nut still in its mouth and that day's coffee break discussion turned into squirrel safety．The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council（市政会）．The council approved，and Council woman Bess LaRiviere jokingly named the bridge"Nutty Narrows"．
    After architects designed the bridge，Amos Peters and Bill Hutch started construction．They built the 60-foot bridge from aluminum（铝） and lengths of fire hose（消防水带）．It cost $1，000．
    It didn't take long before reports of squirrels using the bridge started．Squirrels were even seen guiding their young and teaching them the ropes．The story was picked up by the media，and Nutty Narrows became known in newspapers all over the world．
    In 1983，after 20 years of use，Peters took down the worn-out bridge．Repairs were made and crosspieces were replaced．The faded sign was repainted and in July 1983，hundreds of animal lovers attended the completion ceremony of the new bridge．
    Peters died in 1984，and a ten-foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project．
    14．The underlined words"getting flattened"in the second paragraph mean"beingA"．
    A．killed         B．guided          C．stolen         D．raised
    15．The Nutty Narrows Bridge was built toD．

    C．Spread 60-foot fire hose

    B．it was too narrow
    C．it was too old

    C．Squirrels，Who Cares？
    D．A Worn-out Bridge And Its History．

    3．It was Mother's Day morning last year and I was doing my shopping at our local supermarket with my five-year-old son，Tenyson．As we were leaving，we found that only minutes earlier an elderly woman had fallen over at the entrance and had hit her head on the concrete．Her husband was with her，but there was blood everywhere and the woman was embarrassed and clearly in shock．

    By now paramedics（救援人员）had arrived，and were attending the injured woman．As we walked up to her，my son became intimidated by all the blood and medical equipment．He said he was just too scare d to go up to her．
