How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

How do you know if your home is an easy aim for thefts? Around the holidays, many families don’t consider taking proper measures to prevent their homes from suffering holiday thefts. With just a few simple steps, you can better make sure of the safety of your home during all of the holiday celebrations. Here are a few tips for making it difficult to tell you are away from home.
●Either have a trusted neighbor pick up your mail and newspapers, or tell your mailperson to hold your mail until you return. Nothing says “Hey, we are not home!” like when your postbox is filled with all kinds of mails and you have many different newspapers in your driveway.
● Set several different lights in your house on random timers（随机定时器）. Don't leave your outdoor lights on all the time. Instead, put your outside light on timers to be on during the nights. If an outdoor light remains on for days at a time, it means that nobody is home to turn it off.
● If you have pets that you are not taking with you on vacation, leave them with friend, rather than having someone come into your house every day to take care of them. When thefts see a neighbor or friend entering your house every day, they will know you are not home.
● Close all your curtains when you leave town. This is effective to deter possible thefts, as no one can see what is in your house. If they don't know what there is to take, then the risk is even greater for them to break in.
This article just has suggested a few tips to help you keep your house safe on holiday. Nothing can truly protect your home unless you have it monitored by a professional home security system.

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water,you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the groun.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes itunderground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水层) into which heat several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
【小题1】Which of the following is true according to the first two paragraphs?
| A．Arian de Bondt got his idea from his boss. |
| B．Large, flat, black surfaces need to be built in cities. |
| C．The Dutch engineer's system has been widely used. |
| D．Heat can also be collected from asphalt roads. |
| A．To absorb heat from the sun. |
| B．To store heat for future use. |
| C．To turn solar energy into heat energy. |
| D．To carry heat down below the surface. |
| A．some pipes have to be re-arranged in winter |
| B．the system can do more than warming up the building |
| C．the exchangers will pick up heat from the street surface |
| D．less heat may be collected in winter than in summer |
| A．What we shall do if the system goes wrong . |
| B．What shall we do if there are no asphalt roads |
| C．How the system cools the building in summer . |
| D．How the system collects heat in spring and autumn. |

You can’t hide a natural disaster from children, so how do we prepare them for it? First of all, you should explain to them that acts of nature aren’t necessarily disasters but can become one. These may include floods, hurricanes, tornadoes, winter storms, wild fires, and earthquakes. The way to prepare children for these disasters is to educate them about what each type is and then make it fun by making them “Disaster Masters” or whatever title you can think of.
Making them a Disaster Master won’t be easy. They must know what’s in a disaster emergency kit(工具箱) and why it’s included. You can get your friends involved, too. If your friends have children, they may want to be involved in your emergency preparations. Make it a group project. This is the opportunity for everyone to become familiar with the equipment.
We have to be aware of our conduct and the way we react to stress. The children will be easily influenced by your attitude and demeanor. The calmness, steady manner, and good humor of your spouse (配偶) and you will go a long way toward the easing or the reduction of stress.
Explain to them what they’re likely to encounter or see and describe how people may react. Disasters can come and go very quickly and generally don’t last long. If you must stay away from home, try to get into a routine quickly and encourage them to make new friends. Let them know they can look to their parents and other adults if they become scared or confused. And it’s important to let them know it’s OK to cry during a disaster.
It’s sometimes helpful to let the children draw pictures of what they’ve experienced. Encourage them to write what they learned and what could have been done better. Save the story. Make it part of a documented family history!
【小题1】This passage was written mainly to tell us about ______.
| A．the importance of mutual help in disaster preparation |

Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way -- by studying movements of random floating garbage. A scientist with many years’ experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.
Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1, 600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.
As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.
【小题1】The underlined phrase swap meets in Paragraph 1 is closest in meaning to ______________.
| A．fitting rooms |
| B．trading fairs |
| C．business talks |
| D．group meetings |
| A．what caused the shipping accident |
| B．when and where the shoes went missing |
| C．whether it was all right to use their shoes |

| A．By collecting information from beachcombers. |
| B．By studying the shoes found by beachcomber. |
| C．By searching the web for ocean currents models. |
| D．By researching ocean currents data in the library. |
| A．traveling widely the coastal cities of the world |
| B．making records for any lost objects on the sea |
| C．running a global currents research association |
| D．phoning about any doubtful objects on the sea |
| A．To call people's attention to ocean pollution. |
| B．To warn people of shipping safety in the ocean. |
| C．To explain a unique way of studying ocean currents. |
| D．To give tips on how to search for lost objects on the beach. |

Urban citizens(市民)can enjoy a more colorful life than rural citizens.Townspeople are wellinformed because they have the easier access to news，while country people are uniformed because these districts are hard to get to.Urban traffic is so welldeveloped that the residents there often visit exhibitions and parks which are only a short bus ride away. For country people this is a major operation which involves considerable planning.Shopping，a necessary activity in everyday life is more convenient in the city than in the countryside. Townspeople can buy what they want at any time of a day.But rural residents go to town at most once a week.So after shopping they always stagger home loaded with heavy purchases. As for as meals and clothes concerned，townspeople are wellfed and welldressed as there is an adequate(足够的)supply of goods.But rural residents are too busy to pay particular attention to them.It is for these reasons that more and more people are moving into the city and looking for a rest there.
On the contrary，some people are attracted by the rural area.Air pollution，noise and overcrowding which are the biggest problems confronting townspeople seem strange for rural residents.Medical studies have proved that rural residents can live longer than urban residents, because they are free from a polluted environment. In addition，the crime rate in the city is several times higher than in the countryside.As is known to all，the life in any city is much more expensive than in the countryside.So the safe, quiet and cheap life in the country appeals to(对……有吸引力)many city residents.
Either an urban or a rural area gives pleasure and trouble.But，I believe，the suburban area has the excellencies(优点)of both and is superior to both.As the automobile industry develops，more and more people will make their homes in suburban areas.
【小题1】When visiting an exhibition in town，country people have to ________.
| A．listen to local news | B．take a bus |

When you tidy your messy bedroom，it gets a lot easier to find things.Dreams may work the same way for a messy brain，helping you learn by organizing memories and ideas.
To test how much dreams can help learning，Robert Stickgold had some students play a shapefitting game called Tetris (俄罗斯方块) for a few hours and then go to sleep.Soon they were dreaming of falling Tetris shapes.Interestingly，the worst Tetris players had the most Tetris dreams and improved their game the most.Similar tests have shown the same results for all kinds of skills.
As we dream，many important tasks are getting done.The brain decides what to keep and what to forget.It is connecting new experiences to older learning.In fact，the brain is learning all night long.
Another important task of dreams may be to help us deal with emotions (情绪)．At night，emotions are in the driver’s seat.People who have had an upsetting experience often dream about it afterward.Often the dream event changes somehow—another way the brain tries to make the memory less upset.So if your best friend moves away，you might dream that you’re the one who’s moving.In fact，dreams have a proven power to improve mood，and people who dream about what’s bothering them usually feel better sooner than those who don’t.
Everybody dreams for a couple of hours every night—in the course of your life，you’ll spend about 25 years asleep and 6 years dreaming.There’s probably no single answer to the question why we dream，but there doesn’t have to be.One dream might help you remember your math facts，while another might lead to a new invention，or give you a fun，crazy story to tell your friends.It’s all in a night’s work for our busy，mysterious brains.
【小题1】Robert Stickgold’s test shows that________.
| A．games are useful for memory |
| B．dreams can help improve skills |
| C．players stop learning in dreams |
| D．tasks can only be settled through dreams |
| A．dreams can get rid of sufferings |
| B．only drivers can deal with emotions |

There was great excitement on the planet of Venus (金星). Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week's satellite landing，” Prof. Zog said, “that there is no life on Earth.”
“How do you know this？” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned？”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies？”
“Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won't this set back the flying saucer program several years？”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)．” Profession. Zog replied.
【小题1】According to the passage, the Venusian scientists succeeded in getting important information about ________.
| A．the feasibility of landing a satellite on Earth |

| C．the feasibility of sending a Venus Being to Earth |
| D．the possibility of directing a flying saucer into Manhattan |
| A．they need it in their way to the planet of Earth |
| B．the Earth's atmosphere is filled with deadly gases |
| C．there is a low level of oxygen for Venusians |
| D．there is no air on the planet of Earth |
| A．landing a manned flying saucer on Earth will be carried out soon |
| B．Venusians will land on Earth to help to stop serious pollution |
| C．it's unnecessary to land a manned flying saucer on Earth at present |
| D．pollution on Earth makes it impossible for Venusians to survive there |

In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon (恶魔) that was determined to throw the world into darkness forever. A fitting name, astronomers reasoned, for a threat now rushing towards Earth from outer space. Scientists are monitoring the progress of a 390-metere wide asteroid (小行星) discovered last year, which is potentially on a collision (碰撞)course with the planet.
NASA has estimated that Apophis has an outside chance of hitting the Earth in 2036. If it did hit us, thousands of square kilometers would be directly affected by the explosion but the whole of the Earth would see the effects of the dust sent into the atmosphere. At a recent meeting of experts in Near-Earth objects (NEOs) in London, scientists said it could take decades to design, test and build the required technology to deflect the asteroid.
The Apophis asteroid is placed at four out of ten on the Torino scale—a measure of the threat caused by an NEO where 10 is a certain collision which could cause a global disaster. This is the most possible danger of any asteroid in recorded history and it has a 1 in 37 chance of hitting the Earth.
Alan Fitzsimmons, an astronomer from Queen’s University Belfast, said, “When it does pass close to us on April 13, 2029, the Earth will deflect it and change its orbit. There is a small possibility that if it passes through a particular point in space, the so-called keyhole, the Earth’s gravity will change things so that when it comes back around again in 2036, it will collide with us.” The chance of Apophis passing through the keyhole, a 600-meter patch of space, is 1 in 5,500, based on current information.
There is no shortage of ideas on how to deflect asteroids. The Advanced Concepts Team at the European Space Agency has led the effort in designing a range of satellites and rockets to nudge asteroids that are on a collision course for Earth into a different orbit.
【小题1】The best title for this passage would be ___________.
| A．Apophis Asteroid, a Possible Destroyer of Earth |
| B．Apophis, a Good Name for Dangerous Asteroid |
| C．Our Planet Will Be Ruined in 2036 |
| D．Scientists Study Apophis Asteroid |
| A．powerful | B．mysterious | C．boring | D．destructive |
| A．destroy the quality of |

| C．measure the size of |
| D．look into the truth of |
| A．If Apophis hit the earth, its impact would be enormous. |
| B．No way to deal with Apophis is available at present. |
| C．Apophis is the first dangerous asteroid in recorded history. |
| D．It is uncertain whether Apophis will hit the earth in 2036. |
