The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(***虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.
In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words，we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.

These people have traveled to the countryside more than an hour from Washington, D. C., to get away from the glow of city lights. That"s because they are attending a star party. Star parties are gatherings where professional and amateur astronomers set up their telescopes and invite people to come learn about the night sky. Getting away from light pollution, or artificial skylight from buildings for example, helps stargazers (看星星的人) see objects in the sky much better.
At this star party, Sean O"Brien of the National Air and Space Museum’s Einstein Planetarium starts off by asking the crowd to simply look up and take in all they can see. He points out plenty of things that can be seen without special equipment. Stars, satellites, and even the Andromeda galaxy(仙女座) can be found if you know where to look.
After that, several dozen astronomers offer close-up views. Each has focused their telescope on a different part of the sky. As kids take a look, the owner gives a mini-lesson.
O’Brien says you can have your own star party at home and learn a lot just by paying attention to what"s happening up above. "Watch the sky as the seasons pass, and you will see that it changes," he says. "Or start with the moon. Notice when and where you are seeing it—maybe even in the early morning while you wait for the school bus. "
小题1:What was it special about the Star Party ?
| A．It was organized by the local authority. |
| B．It was carried out without any lights. |
| C．It was so cold that people chatted to cheer up. |
| D．It was held in the town center of Virginia |
a. some invited guests
b. some government officials
c. some experts in astronomy
d. those who were interested in astronomy
e. students who were major in agriculture
| A．a, c, d | B．a, d, e | C．b, d, e | D．c, d, e |
| A．you"d better escape from pollution and sunlight |
| B．you"d better follow Sean O"Brien"s guidance |
| C．you"d better buy some advanced equipment |
| D．you"d better make use of your imagination |
| A．Roman is not built in a day. |
| B．No pains, no gains. |
| C．All roads lead to Roman. |
| D．Time and tide wait for no man. |
In some modern countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “low” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
小题1:The writer of the passage thinks that _______.
| A．education can settle most of the world’s problems |
| B．free education for all probably leads to a perfect world |
| C．free education won’t help to solve problems |
| D．all the social problems can’t be solved by education |
| A．our society needs all kinds of jobs |
| B．our society needs free education for all |
| C．a farmer is more important than a professor |
| D．work with hands is the most important |
| A．to choose officials for the country |
| B．to prepare children mainly for their future work |
| C．to let everyone receive education fit for him |
| D．to build a perfect world |
| A．the means | B．the system | C．the value | D．the type |
Chief technology officer Justin Rattner showed how personal devices will one day offer advice. “How can we change the relationship so we think of these devices not as devices but as assistants or even companions?” he asked.
Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give.
“Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, ” Rattner said, “Future devices will constantly learn about who you are, how you live, work and play.’’
Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer’s entertainment preferences.
As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple’s iPhone and Research in Motion’s Blackberry.
Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices.
The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC.
“I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future,” Rattner said.
But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.
Rattner recognized that questions about privacy and people’s willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off.
“If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.”, he said.
小题1:The future smart phones can do all of the following except _______.
| A．giving responses to the moods of the owners |
| B．giving proposals like assistants or companions |
| C．offering advice to their owners’ friends or relatives |
| D．telling the phone holders or carriers where they are |
| A．iPhone and Blackberry | B．LG and Samsung |
| C．Marvell and Qualcomm | D．Nvidia and ARM Holdings |
| A．Intel Corporation has become the world leader in the smar tphone market |
| B．Intel Corporation has fallen behind in the profitable market for smart phones |
| C．more functions packed into mobile phones will make mobile devices larger |
| D．the smart phone industry is likely to grow 25 percent in the year of 2011 |
| A．Smart phones and Televisions | B．Context-aware Computing |
| C．Personalized Televisions | D．Personalized Smart phones |
A good way to begin is to read aloud a sentence from a book suitable for your child"s reading age. Then ask your youngster to repeat the sentence back to you correctly. Next, reread the sentence, leaving out a particular word. See if your child can identify the word you left out. At the beginning use only simple sentences. Gradually, increase the length of the sentences. Make sure you don’t rush things along too quickly, or your child may become discouraged and tired of the game.
Take your child shopping with you often. He’s to remember a list of items you want to buy in the supermarket. First , ask him to remember only a few things. Then, as he shows increased ability to remember, make the list longer and longer. Praise him often and warmly when he shows increased ability to remember things. He"ll become proud of his ‘good’ memory and will happily play the game.
Encourage your child to learn easy and short poems. As his ability to do this becomes stronger, encourage him to remember longer poems. Do the same with songs.
