As people in Beijing and northern China struggle with severe air pollution this winter,the toxic(有毒的)air is also making life hard for plants and even food crops of China．
"in the last 50 years there has been a 1 6-fold increase in ozone(臭氧)pollution”in the Beijing area，said Hanqin Tian of Auburn University in Alabama,who studies the effects of China's pollution and climate change on plants．
Ozone is particularly harmful to plants because it damages the pores(气孔) on leaves，called stomata,which plants use to regulate how much water evaporates from the leaves．That，in turn，affectS how much water a plant must take up through its roots．Changes in water uptake by plants have been documented in other parts of the world，including the United States，as having major impacts on regional groundwater and surface water supplies．
In studies of the long-term productivity of plants，Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change，has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels．
The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University．Some plants are more resistant to pollutants than others，he said，and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant．
Away from the cities, however, where crops are necded to feed China’s yast population, the effeets of the growing pollution on crops is a significant concern.
“In some ways it affects the crop production and food securiy of China,”said Hanqin Tian.“Air quality is really important for human health, plants and ecosystem and sustainability.”
The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce emissions from cars and industries.ozone does harm to plants mainly by ________.
| A．exposing them to strong sunlight |
| B．damaging the structure of their leaves |
| C．adding more pores to the roots |
| D．making the land unfit for the plants to grow |
Which of the following statement does Hanqin Tian support?
| A．Ozone pollution has increased 1 6 times in the past 30 years． |
| B．Ozone pollution has lowered plant productivity alone． |
| C．Plants can take in a large amount of carbon and other pollutants． |
| D．The toxic air has few effects on food supply in China． |
What Can we infer from the passage?

It is something all humans have evolved to experience-yes, teens everywhere go through this exploratory period.Nor is it unique to people:Even laboratory mice experience a similar stage during their development.
For example，laboratory experiments show that young mice stay close by their mothers for safety. As mice grow．their behavior does too．“When they reach puberty，they’re like，‘I’m gonna start checking out how this environment looks without my mom，…explains Beatriz Luna,of the University of Pittsburgh．
As a developmental cognitive neuroscientist，Luna studies those changes that occur in the brain as children develop into adults．She and other researchers are showing how the teen experience can lead to powerful advantages later in life．Take mice again：Young mice that explore most tend to live longest——that is，unless a cat eats them，Luna adds．What is the best title for the text?

Why is this phenomenon occurring more than ever now and why is it something that seemed almost nonexistent a few short years ago?Experts have certain theories，and all are probably partially correct．One suggestion is over crowding．In the last decade，the number of the cars on the roads has increased by more than 11 percent，and the number of miles driven has increased by 35 percent．However,the number of new road miles has only increased by 1 percent．That means more cars in the same amount of space；and the problem is even serious in urban areas．Also，people have less time and more things to do．With people working and trying to fit extra chores and activities into the day，street levels have never been higher．Stress creates anxiety,which leads to short tempers．These factors，when combined in certain situations，Can induce Road Rage.
You may think you are the last person who would drive aggressively，but you might be surprised．For instance, have you ever yelled out loud at a slower driver,sounded the horn long and hard at another car, or sped up to keep another driver from passing?If you recognize yourself in any of these situations，watch out!

In times of economic crisis, Americans turn to their families for support. If the Great Depression is any guide, we may see a drop in our skyhigh divorce rate. But this won’t necessarily represent an increase in happy marriages. In the long run, the Depression weakened American families, and the current crisis will probably do the same.
We tend to think of the Depression as a time when families pulled together to survive huge job losses. By 1932, when nearly one-quarter of the workforce was unemployed, the divorce rate had declined by around 25% from 1929. But this doesn’t mean people were suddenly happier with their marriages. Rather, with incomes decreasing and insecure jobs, unhappy couples often couldn’t afford to divorce. They feared neither spouse could manage alone.
Today, given the job losses of the past year, fewer unhappy couples will risk starting separate households. Furthermore, the housing market meltdown will make it more difficult for them to finance their separations by selling their homes.
After financial disasters family members also tend to do whatever they can to help each other and their communities. A 1940 book “The Unemployed Man and His Family”, described a family in which the husband initially reacted to losing his job “with tireless search for work.” He was always active, looking for odd jobs to do.
The problem is that such an impulse is hard to sustain. Across the country, many similar families were unable to maintain the initial boost in morale(士气). For some, the hardships of life without steady work eventually overwhelmed their attempts to keep their families together. The divorce rate rose again during the rest of the decade as the recovery took hold.
Millions of American families may now be in the initial stage of their responses to the current crisis, working together and supporting one another through the early months of unemployment.
Today’s economic crisis could well generate a similar number of couples whose relationships have been irreparably(无法弥补地)ruined. So it’s only when the economy is healthy again that we’ll begin to see just how many broken families have been created.In the initial stage, the current economic crisis is likely to __________.
| A．tear many troubled families apart |
| B．bring about a drop in the divorce rate |
| C．contribute to enduring family ties |
| D．cause a lot of conflicts in the family |
In the Great Depression many unhappy couples chose to stick together because_______.
| A．starting a new family would be hard |
| B．they expected things would turn better |
| C．they wanted to better protect their kids |
| D．living separately would be too costly |
In addition to job losses. What stands in the way of unhappy couples getting a divorce?
| A．Mounting family debts |
| B．A sense of insecurity |
| C．Falling housing prices |
| D．Difficulty in getting a loan |
What will the current economic crisis eventually do to some married couples?
| A．It will irreparably damage their relationship |
| B．It will undermine their mutual understanding |
| C．It will help strengthen their emotional bonds |
| D．It will force them to pull their efforts together |
What can be inferred from the last paragraph?
| A．The economic recovery will see a higher divorce rate |
| B．Few couples can stand the test of economic hardships |
| C．A stable family is the best protection against poverty. |
| D．Money is the foundation of many a happy marriage |
