Are you likely to suffer from loss of memory from time to time? Smart cameras can now remind you.

Khai Truong at the University of Toronto in Canada and his colleagues have created a smartphone app that records interactions with household objects. The system involves barcode-like (像条形码的) markers that the user sticks to objects whose use they would like to track.

With the smartphone worn around your neck, the app automatically records a short video clip (片段) when a marked object comes into view. “The user is able to look through the application and see the last time they interacted with it,” says Truong. The app can help people track the state of objects - such as whether they locked a door or switched a light off - as well as routine actions. Ai present, it successfully records about 75 percent of interactions, but only works for fixed objects.

A similar but separate system can solve the problem. E. Akin Sisbot and Jonathan Connell at IBM Research in New York have invented a ceiling-mounted (安装在天花板上的) camera that monitors objects and people. It continuously watches an area, such as a tabletop in your home, tracking the placement of objects in relation to one another. It also remembers who first brought an object into the field of view as well as if anyone moved it afterwards. When asked, “Where is my wallet?” the system might respond, “It is next to the vase, under the magazines.”

The camera could also be used in factories or operating theatres to track vital tools, says Sisbot For now, the camera uses a depth sensor to spot things. It is limited to detecting objects thicker than 3 centimetres, meaning that it has trouble with thin objects such as a closed laptop placed flat on a table.

The accuracy of such smart camera systems may need to improve before they are widely adopted. “You've got to trust the technology for it to be of any comfort or reassurance” says Geoffrey Ward at the University of Essex in the UK.

1.How does the smartphone app mentioned in paragraph 2 work?

A.By recording the movement of marked objects.

B.By informing owners of potential dangers.

C.By switching off electricity automatically.

D.By scanning barcodes of household objects.

2.What is the limitation of the ceiling-mounted camera?

A.It hardly senses objects without barcode-like makers.

B.It fails to find objects thinner than 3 centimetres.

C.It is unlikely to make a sound.

D.It is unable to recognize movable objects.

3.What's Geoffrey Ward's attitude towards the smart camera systems?

A.Supportive. B.Ambiguous.

C.Concerned. D.Sceptical

4.What's the best title for the text?

A.New Smartphones Make Life Easier

B.Smart Cameras Help Increase Home Security

C.New Systems Help People with Memory Problems

D.Camera Designers Face New Challenges

阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Researchers at the Canadian Institute for Advanced Research show how the interaction (交互) between remembering and forgetting in the brain 1. (allow) us to make more intelligent decisions 2. (base) on memory. They published a new review paper in the journal Neuron.

Forgetting makes us smart by working with memorizing 3. the following ways, the researchers say. First, letting go of outdated information lets us adapt to new situations. By forgetting the old and potentially misleading information, we can adapt to new environments 4. (easy). Second, forgetting also makes decision- making simple. We just remember the important information which makes it easy for us 5. (make) wise decisions.

What and how much we remember can 6. (decide) by our environments, For example, a lawyer or a designer with a set of clients will likely remember 7. (they) names for a longer period of time, A cashier who has a changing sea of 8. (customer) every day will only remember names for a short amount of time.

The researchers point out that the motto is true: If you don’t use it, you lose it. But as 9. review paper shows, it can be a good thing. Clearing out the information you don’t need can help make room for the important things, 10. can make you become more intelligent.

New research shows that the healthy brain may hold memories which we don’t even remember. In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky.

Memory Check

First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance(核磁共振) imaging.

While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior（后部的） median temporal lobe(脑叶) -- when they saw words that had been on the first word list.

But participants didn’t always remember that they’d seen those words before. Sometimes, they goofed and said they hadn’t seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants’ consciousness, the researchers note.

“Album”of Memories

Another part of the median temporal lobe also attracted the scientists’ attention. The anterior（前面的）median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows.

So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling(决斗) for the upper hand in deciding what actually happened in the past, the study notes.

In other words, memories might have a photo album in the brain, but sometimes we forget what’s on all of the photo album’s pages.

1.A person sometimes has difficulty recalling because　　　　 .

A. he is unconscious when he gets his memories

B. he forgets what is on the pages of the photo album

C. there are two parts in his brain dueling for the upper advantage

D. the anterior median temporal lobe is more active than the posterior

2.According to the passage the researchers are　　　　 .

A. studying how a person remembers things

B. studying a magazine The Journal of Neuroscience

C. examining posterior and anterior median temporal lobes

D. doing experiments to find out what disturbs a person’s memory

3.What did the experts discover when the participants saw the words on the first word list appear on the second word list?

A. The instrument worked faster.

B. The participants were more conscious.

C. The posterior median temporal lobe was more active.

D. The anterior median temporal lobe was more active.

4. The underlined word“goofed”in the fourth paragraph means　　　　 .

A. made a mess of　　　　　　　　　　　 B. made an answer for

C. made out of　　　　　　　　　　　　　 D. made the best of

Using a computer or smartphone at night can cause us to pile on the pounds，new research has revealed．

The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger．It found that exposure to blue light increases hunger levels for several hours and even increases hunger levels after eating a meal．Blue light exposure has also already been shown to cause decreased　 sleepiness in the evening，increasing the risk of sleeplessness．

The leading researcher，Ivy Cheung，from Northwestern University in Chicago，said，“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢)．These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism．”

The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions，which involved exposure to less than 20 lux(勒克斯，照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep．On the third day they were exposed to three hours of 260 lux，blue-enriched light starting10.5 hours after waking up．and the effects were compared with dim light exposure.

Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure，hunger and metabolism．

1.What is Paragraph 2 mainly about?

A．How blue light exposure affects hunger．

B．Why blue light exposure influences sleepiness．

C．What is the link between blue light exposure，hunger and sleepiness．

D．Who has found the effects of blue light exposure on hunger and sleepiness．

2.The underlined word“novel”in the third paragraph probably means“___________”.

A．unusual　　 B．unforgettable

C．temporary　 D．controversial

3.What can we learn from the passage?

A．Blue light exposure can make us lose weight at night．

B．Blue light exposure has no effect on sleeplessness．

C．The researchers drew their conclusion by comparison．

D．Ivy Cheung has found the relationship between light exposure and hunger．

4.Where would you be most likely to find the passage?

A．On a notice board．　　　 B．In a health magazine．
