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.
小题1:Which is one of the feature of the Kolibree toothbrush?

A．It can sense how users brush their teeth.

B．It can track users’ school performance.

C．It can detect users’ fear of seeing a dentist.

D．It can help users find their phones.

小题2:What can we learn from Serval’s words in Paragraph 3?

A．You will find it enjoyable to see a dentist.

B．You should see your dentist on a day-to –day basis.

C．You can brush with the Kolibree as if guided by a dentist.

D．You’d like a dentist to watch you brush your teeth every day.

小题3:Which of the following might make the Kolibree toothbrush fun?

A．It can be used to update mobile phones.

B．It can be used to play mobile phone games

C．It can send messages to other users

A．They were unwilling to brush their teeth

B．They often failed to clean their toothbrushes.

C．They preferred to use a toothbrush with a dry head.

D．They liked brushing their teeth after Serval came home.

小题6:What can we learn about the future development of the Kolibree?

A．The brush handle will be removed.

B．A mobile phone will be built into it.

C．It will be used to fill holes in teeth

D．It will be able to check users’ teeth

Pulling heavy suitcases all day in the summer is hard work, especially when you are a thin 14-year-old boy. That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station.
After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."
When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in his eye. "They are paying you. If they want to do that, you let them do that."
I followed my dad's advice for the rest of that summer and have lived by his words ever since.
Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possession. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.
Whether you're on a sports team, in an office or a member of a family. if you can't trust one another, there is going to be trouble.
小题1: What can be inferred about the baggage boys?

Nothing could be more shameful for McDonald’s and KFC. They are violating labour’s rights. The government must immediately bring the guilty to justice. A stricter government inspection system must be enforced to protect the workers.
Nathan 2007-03-28 21:39
It is known that McDonald’s and KFC and other fast-food restaurants pay the lowest wage they possibly can to get their employees. I think it’s kind of funny that these two restaurants have not yet set up unions. It is also known that they also take every possible measure e(legal, and sometimes illegal) to prevent their employees from forming or joining unions. I think it is high time that government enforced the law that they have made.
Cushman 2007-03-28 22:32
The deepest reason is that China has a large population. If you complain that the pay is very low, the boss will tell you that can go to other places and that there are a lot of people waiting for the job. Today finding a job is not very easy, so you don’t have many choices, and you have to face the reality.
Chip 2007-03-29 20:33
If wages were too low, people wouldn’t work for them, but they do, so it proves the wages are reasonable. Sure, they could raise the wages, but why should they? The workers are still working, still willing to show up on time, and it keeps costs lower. Were they to raise wages, they would have to FIRE more workers, and the price of burgers would go up. Then people wouldn’t buy them, then McDonald’s would once again FIRE more workers because of a reduced demand, and you’d be back in the same boat, just with less people working.
小题1:What are they debating about?

A．McDonald’s and KFC pay too low a salary to their employees.

B．Setting up a social security system.

C．Fast-food restaurants have no rights to fire workers.

D．McDonald’s and KFC will be punished for their behaviour.

小题2:According to Chip, it is____for McDonald’s and KFC to give employees a low salary.

A．unacceptable

B．shameful

C．acceptable

D．illegal

小题3: In the opinion of Cushman, the key to the problem is that____.

A．the social security net has not been set up

B．China has too large a population

C．the government has not taken stronger steps to protect workers

D．the unions have not played an important part to raise the wages.

小题4: The underlined word “they” in Nathan’s words refers to____.

The Batsquatch is described as a great winged bat. It’s reported that it lives in the shadows(阴暗处) of Mt. Saint Helens. It has purple skin, red eyes and the character is quite similar to the bat’s. Since reports tell it likes eating small animals like chickens, goats and pigs, some believe that it is actually a flying primate(灵长目动物). But researchers say that it is more closely related to the fruit bat of northern America.
Fear still fills the hearts of men, women and children of Washington. In May of 1980 during the eruption of Mount Saint Helens, the Batsquatch showed itself in the shadows of clouds from the eruption.

During this event some farm animals seemed to disappear though luckily no humans were reported missing at the time. The local mountaineer told about his meeting with the Batsquatch. When he suddenly heard a loud deep voice from the shadows, the mountaineer was knocked down. He tried to look for the creature(生物) that had made the sound. He saw a great creature with purple wings in the sky. It looked like it was about 30 feet tall.
The mountaineer kept this story a secret in fear of being laughed at by others but when new stories came in about the Batsquatch he shared his story.
The reality of the Batsquatch can no longer be ignored. It is only a creature that is trying to live. Respect! This is how we should take news such as this. Respect for a living creature instead of fear.

In my long years of teaching, I often ask my students to read the texts until they can recite them, and I tell them that recitation are an important part of their homework. However, some of my students are tired of doing so, thinking that it is both hard and useless. They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper.
In my opinion, it naturally takes time to recite a text, but it is worth doing so. When you are able to recite a text, you are sure to be familiar with the words and expressions. When you need them in reading or writing or doing exercises, they will come to your mind quickly, and so you will give quick response to all kinds of language situation. How can we say that it is useless?
Besides, many students complain that they soon forget what they were once able to recite. This is true, but you don’t need to worry. While you are reading and forgetting the texts, your language level is being raised. Sure you don’t remember your Chinese texts that you once read in the primary school, but now you are able to read novels and newspaper. So, recitation of the texts will help you improve your language ability.
小题1:The writer often asks his students to recite the texts, _______.

A．But they don’t like to do so.

B．And they are eager to do so

C．But they wrote a letter to the Department of Education reporting the thing.

D．But they do more exercises instead of reciting the texts.

小题2:What do the students think about the teacher’s advice?

A．The English teacher tries his best to help them with English.

Passenger pigeons（旅鸽）once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks（群）so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19^th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered（驱散）the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
小题1:In the 18^th and early 19^th centuries, passenger pigeons _______.

A．were the biggest bird in the world

B．lived mainly in the south of America

C．did great harm to the natural environment

D．Were the largest population in the US

小题2:The underlined word “undoing” probably refers to the pigeons’ _______.

A．escape

B．ruin

C．liberation

D．evolution

小题3:What was the main reason for people to kill passenger pigeons?

A．To seek pleasure.	B．To save other birds.
C．To make money.	D．To protect crops.

小题4:What can we infer about the law passed in Michigan?

A．It was ignored by the public.	B．It was declared too late.
C．It was unfair.	D．It was strict.

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放）by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.
‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher，‘consumption patterns of building users can defeat the most careful design. ’In other words，old habits die hard, even in the best-designed eco-home.
Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information，it’s hard to estimate the costs and benefits of making different choices. Feedback (反馈） facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension (方面），suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.
Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.
小题1:As to energy use, the new research from UKERC stresses the importance of________.

A． zero-carbon homes	B．the behaviour of building users
C． sustainable building design	D．the reduction of carbon emissions

小题2:The underlined word “which” in Paragraph 2 refers to”________.”

A．the ways	B．their homes
C． developments	D．existing efforts

小题3:What are Katy Janda’s words mainly about?

A． The importance of changing building users, habits.

B． The necessity of making a careful building design.

C． The variety of consumption patterns of building users.

D． The role of technology in improving energy efficiency.

小题4:The information gap in energy use _______.

A． can be bridged by feedback facilities

B． affects the study on energy monitors

C． brings about problems for smart meters

D． will be caused by building users’ old habits

小题5:What does the dimension added by social science research suggest?

A． The social science research is to be furthered.

B． The education programme is under discussion.

C． The behaviour of building users is unpredictable.

D． The behaviour preference of building users is similar.

We can make all the jokes we want about taking baths ourselves, but if we are ill in bed and can't get up, we'll be thankful to the nurses who help us get clean. While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy (同情) and patience to do so.
Yet those who attended the International Conference on Intelligent Robots and Systems last month were introduced to Cody, a robot that can bathe human beings.
The robot has a base that can be turned to all directions, two humanlike arms, and movable wrists (腕). It uses a camera to locate parts of the human body. It then uses bath gloves to clean with a little pressure.
The robot was designed at the Georgia Institute of Technology. Charles Kemp of the Healthcare Robotics Lab is the senior researcher for the project. In a test run, Cody was able to remove 96% of a test subject's dirt—not bad for a robot.
But don't go asking for Cody yet—he's still a model. Yet researchers believe that one day Cody may take the place of nurses for this task. Researchers say that Cody will give patients dignity and protect their personal information. I suppose that would depend on the patient. I'm not sure whether a robot using a camera would make me feel very dignified.
Even so, I can appreciate the need. We don't have enough nurses to go around, and those places that are the most shorthanded, for example, nursing homes, are those that have the most patients who are unable to bathe themselves. Still, before I get there, I hope they think of a better way to solve the problem.
小题1:The writer thinks bathing others must ________.

A．be a lot of fun

B．make you feel thankful

C．take a lot of patience

D．make you feel dignified

小题2:What is the third paragraph mainly about?

A．Why and where Cody was designed.

B．What Cody looks like and who designed it.

C．What Cody can do and where it will work soon.

D．How Cody works and what has made that possible.

小题3:We know from the fourth and fifth paragraphs that ________.

A．Cody can bathe patients better than a real nurse can

B．robots like Cody are being produced in large numbers right now

C．Cody can take the place of nurses completely in hospitals

D．researchers think Cody can protect patients' personal information

小题4:There is a need for Cody because ________.

A．people are becoming lazier

B．it can bring down the cost of nursing

C．there are not enough nurses

D．there are too many nursing homes

小题5:In the writer's opinion, Cody is ________.

A．acceptable but not perfect

B．strange but not creative

C．clever and strong

D．lovely and careful

One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods.

In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.
Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.
Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(证据)to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.
But so far, no one has found bones or any other definite proof that the giant creature exists.
As a result many people believe the evidence is just part of a big trick.
The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.
They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.
小题1: So far what we can be sure about is that　　　　.

A．there exist savages(野人)in several places in the world

B．there are some traces of hair, footprints and body prints of the “bigfoot”

C．bigfoot is a direct descendent of ancient gigantopithecus

D．all the big foot discovered have the same look

小题2:It was in　　　that man first found the ape-like creature.

A．1999	B．the 1960’s
C．the 1950’s	D．the 1940’s

小题3: The article infers but doesn’t say so that some people　　　　bigfoot’s existence.

A．may fool the world into believing

B．have definite evidences to prove

C．refuse to believe

D．will soon offer proofs of

小题4:If bigfoot is just a misunderstanding, what they saw might NOT be　　　　.

A．apes

B．bears

C．gigantopithecus

D．people dressed in animal skins
