In the middle of my home country there are very large places. They are hot and dry land called deserts.
About 65 years ago these people found that using strong radios was a possible way for families living far away to communicate with each other. They decided they could use the radios for school. In this way, children could talk to each other like at school.
The children each spent about 30 minutes a day on the radio. They talked to their teacher about their work and difficulties. The teacher designed some exercises and tasks based on what they learned and posted them to the children.After finishing their work, the children sent it back to their teacher to mark.
| A．The teacher also travelled around the country. |

| C．The strong radios helped the children a lot. |
| D．This was how the first "School of the Air"started |
| E．These families' children cannot go to school like you. |
| F．With the development of technology, computers are becoming popular. |
| G．After that, these families become richer and richer |

【推荐1】Riding a London subway, a person from China will notice one major difference: in London, people do not look at each other. That's not rudeness-people are just too busy to bother(费心)looking.
Busy doing what? Well, they're certainly not using the time for reflection, nor are they reading a book. New technology has replaced quiet habits. Today the only acceptable form of book on the London underground is an e-book.
Apple must earn a fortune from London commuter(乘车上下班的人).Since the launch of the iPhone in 2007, over 40, 000-yes, that's 40, 000-"apps"(programs downloaded for the iPhone) have been designed.
Commuters love them. One "app", called iShoot, is a game that features tanks(以坦克为特色). Another one, Tube Exits, tells passengers where to sit on the subway to be closest to the exit of their destination. ISteam clouds the iPhone screen when you breathe into the microphone(麦克风). You can then write in the "steam" on your phone screen.
For those without an iPhone, another Apple product, the iPod, may be another choice. It's not just teenagers who "plug in" to their music-iPods are a popular way to pass the time for all ages.
And if games, e-books and music aren't enough to keep you occupied, then perhaps you would prefer a film. The development of palm(手掌)DVD technology means many commuters watch their favorite TV show or film on the way. With all this entertainments, it's amazing that people still remember to get off the subway.

【推荐2】Imagine you’re a farmer in India with a crop of potatoes to sell. Typically, you go to a marketplace called a mandi and get the best price you can from a local middleman, who will then sell them to another middleman.
Sanjay Agarwalla learned about Indian farmers’ lack of access to buyers even when he was a student decades ago. After talking the problem over with his son Aditya, then a computer science major at Princeton University, the two decided to form an online marketplace they called the Kisan Network in late 2015.
“Anything that deals with agriculture in India is pretty large. So, if it’s a problem, the problem can affect millions of people, and the impact of the solution could be enormous,” Sanjay says. After all, some 70 percent of rural households in the country depend on agriculture as a main source of income.
Kisan Network’s app lets farmers advertise their produce and see potential buyers beyond the local mandi. Once the deal is completed online, Kisan runs the produce from the farmer direct to the buyer, each side staying put.
Kisan’s fee ranges from 5 to 15 percent of the sale, and farmers get to keep more than they would under the traditional system, where middleman after middleman raises the price of the produce before it reaches a final buyer. “Even with low-profit crops like potatoes, we have been able to offer 10 percent more than physical market rates. That’s what our entire goal is,” says Aditya. “As for higher-profit crops, the improvement goes up.”
Building products for this new set of technology consumers brings its own challenges. “All of our engineers are from urban backgrounds,” says Aditya Agarwalla. “It’s not like you’re building something you would use on your own.” To be effective, Kisan’s platform must work with inexpensive smartphones on slower networks and be able to support regional languages.
Today, farmers feel it’s better selling to someone who is at their doors. They do not have to typically travel miles to a mandi, staying overnight without a place to sleep.
