Technology and the present generation of kids go hand in hand. Taking advantage
题型：不详难度：来源：
Kidget, as the name suggests, is a combination of two words – kid and gadget. This kid-friendly gadget has various uses. When your child is in a mood to read, it takes the form of a storybook. When the mood is to draw and color this wonder gadget turns into a perfect canvas (画布). Your child can freely give color to all his/her imaginations. Should he or she wish to have some fun, see this device change into a musical instrument. You too would enjoy doing activities with your loved one using this gadget. This touch screen device will definitely prove to be an ideal friend.
As many parents agree, in this age of technological advancements it is much easier to introduce children to new gadgets than adults. While many adults refrain (克制) from trying out something new, kids are more than prepared to take the leap. Keeping this fact in mind, Kidget is the perfect gift for the child of the 21st century. You will be surprised to see how fast your little one gets acquainted with the device. You might even find yourself lagging (落后) behind at times.
Kidget has another hidden advantage. It helps take the load off young shoulders. With three things rolled into one, a child has much less books, stationary items and related goods to carry. It comes with a promise to make life simpler for kids. Not only is it simple to use but also easy to carry along. The stylish protective case comes with a belt attached to it. Children up to 14 years of age, the targeted audience, enjoy the freedom that comes with it.

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.”
小题1:For what purpose did Nest create the Protect Smoke Alarm?
| A．To predict low-level fire risks. | B．To experiment with a new battery. |
| C．To improve present smoke alarms. | D．To avoid the low-battery chirp. |
| A．One of his cooking experiences. |
| B．Disadvantages of present smoke alarms. |
| C．His growing distrust of smoke alarms. |
| D．His source of annoyance to crying wolf. |
a. Rechargeable batteries b. A talking smoke alarm
c. Longer battery life d. Going off constantly
e. Internet connection
| A．a, b, c | B．c, d, e | C．a, c, e | D．b, c, e |
| A．In the UK people seldom set up smoke alarms. |
| B．Matt Rogers didn’t like the safety requirements. |
| C．Non-functioning smoke alarms make people annoyed. |
| D．The government should pay attention to safety issues. |
A first step towards genetic mugshots has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations(突变) that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had “significant effects” on facial appearance.
Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: “We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can’t go from DNA to a face, or from a face to DNA, but it should be possible.” The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated “e-fits” based on witnesses’ recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA.
The scientists wrote in the online journal Public Library of Science Genetics: “Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools.” The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces.
Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.
小题1:The underlined word “mugshots” in the second paragraph most probably means _________.
| A．different faces | B．characteristics | C．pictures of faces | D．genders |
A. DNA has been used to build up a picture of an offender’s face.
B. It may be much easier to catch criminals with the help of DNA.
C. In all, 20 genes had “significant effects” on facial appearance.
D. One gene can affect more than one part of your face.
小题3:According to Professor Mark Shriver, we know_________.
| A．they can merely match to an individual or identify an individual |
| B．there is a possibility of going from DNA to a face |
| C．DNA could be used to produce a rough image of an offender’s face |
| D．this technology is more reliable than computer-generated “e-fits” |
| A．Creating a data bank of DNA |
| B．Recognizing the DNA of criminals |
| C．Predicting the location of offence using DNA |
| D．Building image of offender’s face from DNA |
The traveling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest, and it can keep computers busy for days. However, bees solve it without computer assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains, “Bees solve traveling salesman problems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum. ”
The team used the computer to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.
As well as improving our understanding of how bees move around the landscape pollinating(授粉)crops and wild flowers, this research, which is due to be published in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday networks without needing lots of computer time. Dr. Raine adds, “Despite their tiny brains, bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a computer. ”
小题1: What would be the best title of the passage?
| A．Bees help salesmen travel |
| B．Tiny-brained bees solve a complex mathematical problem |
| C．How bees discover the flowers |
| D．How to solve the “traveling salesman problem” |
| A．can be solved by a computer easily |
| B．can’t even be solved by a computer |
| C．can puzzle both people and computers |
| D．remains to be solved by scientists |
| A．provide further proof for the research |
| B．tell us how bees can fly the shortest route between flowers |
| C．tell us how the research about bees’ flying route was conducted |
| D．explain the importance of the research |
| A．all creatures are smarter than computers |
| B．the research about bees’ flying route can be applied to many fields |
| C．our networks are more complex than bees’ ones |
| D．with the help of the computer we can find out how bees can solve the “traveling salesman problem” |
Ever since the “Back to the Future” movies lit up our screens in the 1980s, designers have dreamt of cars that could take to the sky at the push of a button(按钮). And now pilots can order their own “roadable” plane for just￡127, 000.
The plane, which has fold-out wings that span 17. 5 feet, can be up to 115 mph. Back on the land, it can also travel at “highway speeds” in car mode(模式).
Fuelling(加燃料)the 19 feet long plane couldn’t be simpler—you just drive it into a petrol station and fill it up.
A spokeswoman said, “You can keep your ‘light-sport airplane’ in your garage. But because it needs a short runway to take to the air, you will have to drive to your local airport, fly up to 460 miles, land and drive directly to your destination(目的地). You will always be ready to drive or fly. ”
The spokeswoman added, “Never let bad weather change your trip. You can simply divert(使转向)and continue on the ground until the weather clears. ”
There’s no risk to you—this is only the chance for you to be the first at your home field to unfold(展开)your wings and fly into the future.

| B．show people the use of the “roadable” plane |
| C．tell people only the “roadable” plane can fly in the future |
| D．ask people to unfold their wings and fly into the future |
| A．land in a nearby airport until it clears |
| B．turn back home until it clears |
| C．land and drive on the ground |
| D．fly high up to 460 miles |
Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between
100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
小题1: According to the passage, the planet Mars has no on it.
| A．winds | B．dust |
| C．mountains | D．animals |
| A．there is a large amount of ice at the poles |
| B．there is a thicker and warmer atmosphere |
| C．there are some kinds of simple plants |
| D．there are many active volcanoes |
| A．Certain gases should be used to warm the Mars. |
| B．Plants should be grown to make the Mars fit to live on. |
| C．The Mars could support life on right conditions in the future. |
| D．People could live on the Mars in a special closed environment. |
| A．No Life on the Mars |
| B．Study of the Mars |
| C．The Possibility of Life on the Mars |
| D．Future Conditions on the Mars |
