Bad teeth may be painful and it’s getting worse without treatment. They can even ruin your life. Illness of the teeth can find its way into the blood system. This can increase the chances of a heart disease or other illnesses.
Experts say good care for teeth should start at birth. Mothers’ milk is the best food for the healthy development of teeth.
But dentists say a baby’s mouth and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, give him only water.
When baby’s teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. Young children often eat toothpaste (牙膏) when they brush, so they should be carefully watched when they brush their teeth.
Parents often ask what effect thumb sucking (咬手指) might have on their baby’s teeth. Experts generally agree that this is fine early in life. Most children stop sucking their thumbs by the age of four. If it continues, parents should talk to their children’s dentist or doctor.
Dentists say children should have their first dental visit by the time they are one year old. They say babies should be examined when their first teeth appear usually at around six months.

Boredom and Creativity
Most of us think of being bored at work as a negative experience, but a new study suggests it can have positive results including an increase in creativity because it gives us time to daydream.
That is the finding of Dr. Sandi Mann from the University of Central Lancashire. Dr. Mann conducted two studies. In the first experiment, 40 people were asked to carry out a boring task. They were told to copy numbers out of a telephone directory for 15 minutes. After that they were asked to complete another task. A pair of cups were given to each of them. Everyone tried to come up with different uses of the cups, and was given a chance to display their creativity. Meanwhile, another group of 40 people were just asked to come up with uses for the cups without doing any boring tasks before. It turned out that the 40 people who had first copied out the telephone numbers were more creative than the control group(对照组).
To see if daydreaming was a factor in this effect, a second boring task was introduced that allowed even more daydreaming than the boring writing task. This second study saw 30 people copying out the numbers as before, but also included a second group of 30 reading rather than writing them.
Again the researchers found that the people in the control group were least creative, but the people who had just read the names were more creative than those who had to write them out. This suggests that more passive boring activities, like reading or perhaps attending meetings, can lead to more creativity. Compared with reading, writing reduced the scope（范围） for daydreaming. As a result, it reduces the effects of boredom on creativity.
Dr. Mann says: “Boredom at work has always been seen as something to be avoided, but perhaps we should accept it in order to promote our creativity. What we want to do next is to see what the practical implications of this finding are. Do people who are bored at work become more creative in other areas of their work -- or do they go home and write novels?”
【小题1】Who proved to be the most creative in the two studies?
| A．The people who attended meetings. |
| B．The people who did the reading task. |
| C．The people who invented uses for cups. |
| D．The people who copied telephone numbers. |
| A．creative tasks |
| B．controlled activities |
| C．the range of daydreaming |
| D．reading and writing ability |
| A．Positive. |
| B．Skeptical. |
| C．Subjective. |
| D．Disapproving. |
| A．The real causes of creativity. |
| B．The actual use of boredom. |
| C．The practical reasons of boredom. |
| D．The writing ability improved by boredom. |

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小题1】What can we learn from Paragraph l?
A. Driverless vehicles are now legal in the whole USA.
B. Volvo will be the first to sell driverless cars.
C. Driverless cars are pointing us' a faraway future.
D. Google's self-driving cars have covered a long distance.
【小题2】We learn that Governor of California Jerry Brown_________.
| A．helped design self-driving cars. |
| B．supports self-driving cars on roads. |
| C．considers self-driving cars science fiction. |
| D．improved the self-driving car systems. |
| A．They can help people drive more safely. |
| B．They can take the place of drivers now. |
| C．They can make cars run without fuel. |

Chinese parents are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter.
However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize, though, is that today’s children lack self-respect and self-confidence.
The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them,tying to fix them ,your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.
【小题1】Parents in China according to this passage .
| A．are too strict with their children |
| B．are too rich to educate their children |
| C．have some problems in educating their children correctly |
| D．have no problems in educating their children strictly |
| A．the parents’ ideas of educating their children |
| B．the education system of the school |
| C．children’s skills in cooking at home |
| D．children’s hobbies in the classroom |
| A．learn how to serve their parents |
| B．learn how to become strong and fat |
| C．get a lot from it and prepare themselves for the future |
| D．make their parents believe that they are clever |
| A．broken radios and television sets are useful |
| B．one’s interest and curiosity may be useful for his later life |
| C．an engineer must fix many broken radios |
| D．a good student should spend much time repairing radios |

The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol.
It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012.
A “green” city might work on several kinds of environmental goals and programs.These include air quality，reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation.
The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps.
Washington，D.C.is also a leading city for green roofs，with over 92,000 square meters of green rooftops.The city also launched a program called “Skip the Bag，Save the River.”Stores charge people a fivecent tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river.
New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices.
The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged.
In Oakland, California, you can ride on one of several public hydrogenpowered(氢气作燃料的) buses.These buses release zero pollution into the air.However，they cost about five times more than common buses.

(2013·高考浙江卷，C)The baby monkey is much more developed at birth than the human baby.Almost from the moment it is born，the baby monkey can move around and hold tightly to its mother.During the first few days of its life the baby will approach and hold onto almost any large，warm，and soft object in its environment，particularly if that object also gives it milk.After a week or so，however，the baby monkey begins to avoid newcomers and focuses its attentions on“mother”—the real mother or the mothersubstitute(母亲替代物)．
During the first two weeks of its life warmth is perhaps the most important psychological(心理的)thing that a monkey mother has to give to its baby.The Harlows，a couple who are both psychologists，discovered this fact by offering baby monkeys a choice of two types of mothersubstitutes—one covered with cloth and one made of bare wire.If the two artificial mothers were both the same temperature，the little monkeys always preferred the cloth mother.However，if the wire model was heated，while the cloth model was cool，for the first two weeks after birth the baby monkeys picked the warm wire mothersubstitutes as their favorites.Thereafter they switched and spent most of their time on the more comfortable cloth mother.
Why is cloth preferable to bare wire？Something that the Harlows called contact(接触)comfort seems to be the answer，and a most powerful influence it is.Baby monkeys spend much of their time rubbing against their mothers’ skins，putting themselves in as close contact with the parent as they can.Whenever the young animal is frightened，disturbed，or annoyed，it typically rushes to its mother and rubs itself against her body.Wire doesn’t “rub” as well as does soft cloth.Prolonged(长时间的)“contact comfort” with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.
According to the Harlows，the basic quality of a baby’s love for its mother is trust.If the baby is put into an unfamiliar playroom without its mother，the baby ignores the toys no matter how interesting they might be.It screams in terror and curls up into a furry little ball.If its cloth mother is now introduced into the playroom，the baby rushes to it and holds onto it for dear life.After a few minutes of contact comfort，it obviously begins to feel more secure.It then climbs down from the mothersubstitute and begins to explore the toys，but often rushes back for a deep embrace(拥抱)as if to make sure that its mother is still there and that all is well.Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother”．
【小题1】Psychologically，what does the baby monkey desire most during the first two weeks of its life?
| A．Warmth. | B．Milk. |
| C．Contact. | D．Trust. |
| A．larger in size |
| B．closer to them |
| C．less frightening and less disturbing |
| D．more comfortable to rub against |
| A．Attention. | B．Softness. |
| C．Confidence. | D．Interest. |
| A．it frequently rushes back for a deep embrace when exploring the toys |
| B．it spends more time screaming to get rewards |
| C．it is less attracted to the toys though they are interesting |
| D．it cares less about whether its mother is still around |
| A．give the reasons for the experiment |
| B．present the findings of the experiment |
| C．introduce the method of the experiment |

Yawning sends out certain messages -either “Oh ，this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ，which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
【小题1】The purpose of the experiment is ______.
| A． to prove people yawn in winter and in summer equally |
| B． to indicate brain can regulate temperature naturally |
| C． to find the frequency of people’s yawning |
| D． to show the real reason why people yawn |
| A． longer outdoor summertime results in more yawns |
| B． yawning frequency changes with outdoor time |
| C． yawning frequency increases with outdoor time |
| D． longer outdoor wintertime leads to fewer yawns |
| A． Yawning Is A Sign of Brain Disease |
| B． Yawning Carries Some Information |
| C． Yawning Benefits Your Body |
| D． Yawning Cools Your Brain |

China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard (车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
【小题1】The author writes this passage mainly to________.
| A．teach people how to drive a hybrid car |
| B．introduce a new kind of “green” car |
| C．show how to save their gasoline when driving a car |
| D．announce plans to develop hybrid vehicles for China |
| A．The hybrid cars reduce air pollution and oil shortages. |
| B．The car's gasoline engine doesn't work until it reaches about 24 km/h. |
| C．This kind of car is completely controlled by an onboard computer. |
| D．A specially designed battery motor provides extra power when needed. |
| A．They are powered by both a rechargeable battery and gasoline. |
| B．They are much quieter than traditional cars. |
| C．They only use 99 percent of their power to run up hills. |
| D．They have smaller engines than traditional gasoline ones. |
| A．The batteries can be recharged at any time you want. |
| B．Using the brake suggests that the gasoline engine should work. |
| C．The batteries will last for 200, 000 miles without being recharged. |
| D．The gasoline engine charges the batteries as well as powers the car. |
