The £109 Nest Protect Smoke Alarm promises Internet alerts(警报)and an end to the low battery chirp(短而尖的叫声). Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep(嘟嘟声). And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”

Going green seems to be a fad(时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.
On April 22,2012, we decided to go green every single day for an entire year. This meant doing 365 different green things, and It also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.
With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic(有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.

You may be fascinated with pictures of animals in the wild. You might have imagined yourself taking pictures of animals that are rarely seen in the city. If you do get that chance, you may want to consider the following tips or rules.
First of all, a lot of professional photographers give respect to these animals and the environment they are in. Just remember that you should respect the animals and the environment in case these animals bite or hurt you.
Keep in mind that you are taking pictures of real, live, wild animals. A wild animal may bite to protect itself. You must be sensitive while taking their pictures and be gentle in all your movements. Do not feed the animals, or interact with animals that are sleeping or caring for their young.
If you are going to a place where it is privately(私人)owned, you’d better get the owner’s permission first before you start taking pictures.
Change the flash of your camera to natural light, so the animals will not be frightened or surprised when you start shooting. Animals do not react well when they are surprised.
Be very patient. Make sure you are aware of the changes in behavior of the animal and its moods. Be familiar with the animals’ natural habitat.
Now if those rules are clear, it is time for planning. Consider the weather; some animals do not go out when it is raining while some animals love the rain. Therefore, a little research on the weather will not hurt. You should consider taking pictures after sunrise and before sunset. Now if the animal is nocturnal(夜间活动的), then you should prepare to battle not only the wild but also the darkness.
An adventure in the wild will make you very excited. However, you should be well equipped, have experts to back you up, and also a permit for doing the photo shoot. If you do not have any of these, then maybe you should consider visiting the zoo instead.
【小题1】The main purpose of the author in writing this passage is .
A.to call for us to protect animals |

Bananas are one of the world’s most important food crops. They are also one of the most valuable exports. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses. For example, the Cavendish banana is most popular in North American and European markets. However, some kinds of fungus organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plants’ leaves. Farmers put anti-fungal chemicals on their crops up to once a week.
Another fungal disease is more serious. Panama disease attacks the roots of the banana plants. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America.
The International Network for the Improvement of Banana and Plantain supports research on bananas. The group has headquarters in France and other offices in the major banana-growing areas of the world. The group says that more research must be done to develop improved kinds of bananas. The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five hundred different kinds of bananas. Food and Agriculture Organization of the United Nations has said that the Cavendish banana represents only 10% of world production.
The U. N. agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This happened earlier to another popular banana because of its genetic weakness against disease.

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.
“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”
Wang and his colleagues developed their software to locate and track:
Targets of known size—when the size of the target is known.a single image is enough to pinpoint the target’s location.
Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery life and camera resolution will allow our software to make even more accurate observations.”
【小题1】From Paragraph 1 we can know that the new software can.
A.determine the speed of moving objects |

A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus(刺激)from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month old son of Dr. and Mrs. Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag(滞后)in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant(婴儿) Dennis is learning to identify the people and objects in the world around him by means of echoes(回声).
The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超声的) pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音调) and volume(音量) with the size and distance of the object.
The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny’s sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound(超声波) passes its edges. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. “From the first time he wore it,” says Mrs. Daughters, “it was like a light going on in his head.”
What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment.
Meanwhile, Telesensory, Inc, is working on the development of sonar(声纳) device with somewhat the same sensitivity as Dennis’s for use by school-age children.
【小题1】Dr. and Mrs. Daughters’ research is directed to ________.
A.helping the blind to see and learn as well as others |
B.benefiting the learning process of blind children |
C.solving blind children’s psychological problems |
D.finding out how children develop intellectually |
A.he already lags behind the sighted children |
B.he leads a life as normal as any other children |
C.he is at the early stage of the learning process |
D.he has the aid of a sonar-type electronic device |
A.Its first design was designed for blind adults. |
B.Its battery is as small as a half-dollar coin. |
C.It is functionally similar to a sane and guide dog. |
D.It has been improved by Telesensory Systems, Inc. |
A.the edge of an object |
B.the edge of the device |
C.the boundary of Dennis’ movement |
D.the boundary of the sound pitch. |

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it!”
But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.
【小题1】According to the first paragraph,________.
A.the function of our brain is like that of the muscle |
B.until now it's impossible to explain the brain's mystery |
C.many people believe one's intelligence is naturally determined |
D.one's brain grows stronger as the age increases |
A.using the brain |
B.connecting things in your brain |
C.lifting weights |
D.doing research about the brain |
A.Strong. | B.Smart. | C.Popular. | D.Active. |
A.the differences between animals’ brains and humans’ brains |
B.the relation between human brains and muscles |
C.scientists’ findings about animals’ brains |
D.how to make your brain smarter through self-development |

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pet in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
【小题1】The word shelter in paragraph one means:
A.warm clothes | B.a hiding place | C.proper temperature | D.diet food |
A.They are often forgotten by their owners. |
B.They like to stay in warm places. |
C.They build their own shelters. |
D.They are used to living outdoors. |
A.To keep company. |
B.To keep them from eating bad food |
C.To help them find shelters. |
D.To know when to bring them inside |
A.run short of clean water | B.dig deep holes for fun |
C.dirty the snow nearby | D.get lost in the wild |
A.To solve a problem |
B.To give practical advice |
C.To tell an interesting story |

Coffee is a powerful beverage.On a personal level,it helps keep US awake and active.On a much broader level,it has helped shape our history and continues to shape our culture.
Coffee didn’t take off until the l400s when people figured out they could roast its seeds.By the l500s,the drink had spread to coffeehouses across the Arab world.Within another l50 years,it took Europe by storm.
“It actually had a major impact on the rise of business,” historian Mark Pendergrast says.Coffeehouses became a spot not just to enjoy a cup but to exchange ideas.The insurer Lloyd’s of London was founded hundreds of years ago in one of London’s 2,000 coffeehouses.Literature,newspapers and even the works of great composers like Bach and Beethoven were also spawned(涌现)in coffeehouses.
It is often said that after the Boston Tea Party of l773,when American colonists attacked British tea ships and threw boxes of tea into the harbor,Americans universally switched over to drinking coffee.In a letter John Adams wrote to his wife,Abigail,the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead,because drinking tea had become a symbol of not loving the country.
For all the upsides coffee has brought the modern world,it also led to its fair share of downsides,too.Europeans carried coffee with them as they colonized various parts of the world,and this frequently meant they enslaved people in order to grow it.In Brazil — where slavery was legal until l888 — coffee plantations would use slash-and-burn agriculture,tearing down rain forests and planting coffee trees.Once the soil had been exhausted,growers would move on to another place.
And yet,coffee,as Pendergrast says,”had a very good impact in many ways on our civilization,even though it was,for a long time,grown by slaves.”
【小题1】Why did people enjoy going to coffeehouses?
A.Because it was a fashion to drink coffee. |
B.Because coffeehouses provided a better flavor. |
C.Because they could stay awake and active there. |
D.Because they could exchange ideas there. |
A.American colonists made great profits by trading in coffee. |
B.Tea was regarded as a symbol of loving one’s country. |
C.Coffee became very popular after the incident in Boston. |
D.John Adams was the Founding Father of the Tea Party. |
A.Coffee plantation was closely connected with slavery |
B.coffee plantation led to outdated agriculture in Brazil |
C.slavery in Brazil had been against the law until l888 |
D.slavery was responsible for the damage to rainforests |
A.Some interesting stories about coffee culture. |
B.Important Roles that coffee played in history. |
C.How coffee became the most popular beverage. |
