There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.The first kind of physical activity must be strictly controlled because _________.
| A．a mistake in the wrong direction is dangerous to the fingers |
| B．a wrong movement in a direction will cause no mistakes |
| C．a movement in the wrong direction will cause a mistake |
| D．a slight movement of a finger will lead to a mistake |

| B．the physical exercise had more harmful effect on the hearts of the untrained patients |
| C．the physical exercise was harmless to the male patients with heart trouble |
| D．the physical exercise could be helpful for the patients to take in more oxygen |

London used to be “foggy”（有雾的） for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog（烟雾）, a mixture of smoke and fog．In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal（煤）that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel（燃料）, like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.What was the main reason for air pollution in London?
A．There was too much smoke in the sky．
B．There were too many factories in the city．
C．People burnt too much coal in the houses．How did the air in London become much cleaner?
A．There was not so much fog in the winter later．
B．A law was made to keep people from burning coal in their houses．
C．Many factories in the city were closed．What does the underlined work “pea-soupers” refer to?
A．Smog.B．Smoke.C．Gas.The problem of air pollution is more difficult for Chinese cities to solve because of _____reasons
A．one B．twoC．threeWhich sentence is Not true?
A．Using coal is much more expensive than using gas.
B．Factories made much more pollution in China.
C．The reasons of air pollution in London and Beijing are different.
No Car Day was first started by 34 cities in France on September 22, 1998．It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.
The first No Car Day in China was in Chengdu in 2001．Other cities, including Taipai, Shanghai and Wuhan, also support the day.
In Beijing, more and more people are joining the campaign（运动）. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5 （World Environment Day）. The slogan for the day is, “If we drive for one less day, we can have one more nice day.”
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive,” said Wu Zonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of 2012, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period the year before. Much of the dust（灰尘） comes from the desert, but cars cause most of the air pollution. We must do more for No Car Day.The first No Car Day fell on _______.
A．February 2ndB．June 5thC．September 22nd_______ was the first city to have No Car Day in China.

Plastic is everywhere because plastic is an extremely useful material．It is cheap, strong and lightweight．What’s more, it can take on nearly any form or shape, from soft and stretchy （有弹性的） to hard and glasslike.
Plastic, however, is far from perfect．It may even be bad for us．Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder （注意缺陷障碍）.
Two types of chemicals in particular have raised special concern lately．They are called phthalates （邻苯二甲酸盐） and Bisphenol-A （二酚基丙烷）, BPA for short． Not all plastic products contain them．But the ones that do are surrounded by controversy （争议）．That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing．What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture．Plasticizers （塑化剂） are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways．Phthalates add softness to things like shampoo bottles, raincoats and rubber．They are also used in perfumes and makeup．BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles．BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep （渗透） out of the plastic．Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic．Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three．California and Washington have done the same．And a number of other states are considering similar rules．As for BPA, Canada became the first country to ban the chemical from baby bottles．A dozen states are considering it.What can we know about the plastic from the first paragraph?
| A．Its characters and effects． | B．Its wide use and bad points. |
| C．Its importance and chemicals． | D．Its popularity and advantages. |
Which of the following products contains BPA?
| A．A soft plastic cup． | B．A pencil eraser. |
| C．A baby milk bottle． | D．A new perfume. |
Phthalates and BPA can get into us __________．
| A．through mouth or nose |
| B．through blood transfusion |
| C．by feeling plastic products |
| D．by heating in the microwave |
What is the passage mainly about?
| A．A new ban on plastic products． |
| B．Problems caused by the plastic． |
| C．Good points of the plastic． |
| D．The use of plasticizers. |
Marjorie Baer used to joke about her retirement plans．She wasn't married and had no kids, but she didn't intend to be alone—she and all her single friends would move into a fictional home she called Casa de Biddies．Instead, Baer developed terminal brain cancer when she was 52．But just as she'd hoped, her friends and family provided her with love and care to the end．
Ballance was only the first of Baer's friends who became her unofficial caregivers．With her brother Phil Baer from Los Angeles, they worked out a system to watch over their friend and allow her to keep some of the privacy and independence she cherished.
Baer's good friend Ruth Henrich took Baer to doctors' appointments and helped her deal with all the aspects of life —answering machines, TV controls, and even phone numbers．After Henrich sent out an e-mail request, a group of volunteers signed up to ferry Baer back and forth to radiation therapy（放疗）．Others in Baer's circle offered up particular talents: A nurse friend helped Baer figure out how to get what she was due from Social Security and her disability insurance; a lawyer pal helped Baer with her will; a partner who was an accountant took over her bills when she could no longer manage them．"There was this odd sense that the right person always showed up," says Ballance．Their arrangement worked remarkably well．
Unmarried women are one of the fastest-growing groups in America; experts are concerned about how care-giving will be managed for them as they age．If the experience of Baer's friends is a guide, the Internet will play a role．It's already making it possible to create communities of caregivers who may have only one thing in common: the person who needs their help．On personal "care pages" set up through services such as Lotsa Helping Hands, friends and family members can post a list of tasks that need to be done, volunteer to do them, and keep updated on the person's condition．As Baer's cancer progressed, for example, her friends set up a page on Yahoo! where people could sign up to deliver meals or do errands（差事）.
Catherine Fox, one of the friends who were present when Baer died, was deeply affected．"It was so comforting to know that if you're willing to ask for help, the generosity of family and friends can be phenomenal（显著的）．It makes me feel secure and hopeful to know that help is there when you need it．"The most appropriate title of this passage should be ______．
| A．On her own, but not alone |
| B．A friend in need is a friend indeed |
| C．A new practice of American government |
| D．A phenomenal advantage of the Internet |
