1 . A roadside system that detects if a mobile phone is in use in a passing vehicle is being tested in the UK first. Despite being unable to tell whether the driver is using the phone, it is hoped that it will act as a warning to people who make calls behind the wheel. The technology picks up the phone signal in the vehicle and activates(激活) a roadside warning sign of a mobile phone with a red line through it.

The system can’t tell the difference between a driver and a passenger on a bus, but to some degree it can warn drivers that they can be detected using their phones. Using a directional antenna(天线)，the detector picks up radio waves produced by a phone handset , and measures the signal strength and length of them. When a signal is detected of duration(持续时间) long enough and signal strength strong enough to set off the system， the detector activates the warning sign. The detector is able to distinguish Bluetooth connections or hands- free devices which, when picked up，will prevent the activation.

While this new system is no replacement for a police officer catching someone in the act， it could be enough to make some drivers think twice- and that has to be a positive step forward. However, just as technology has enabled the problem of drivers using mobile phones illegally, it can also be a big part of the solution in getting people to stop. Statistics from the devices will be shared with Norfolk Police， the county council said. The council said that enabling the system to record specific number plates could be a“future development”.

Using a mobile phone at the wheel is one of the four road crimes which can have horrible consequences if it causes a deadly or serious car crash. Law enforcement(执行) technology has been falling behind for a decade and not made any easier by motor producers that encourage users to plug in their phones even before driving.

6 . The 90-minute documentary, Amazing China, which is co-produced by China Central Television and China Film Corp, opened in theatres nationwide.

The film focuses on the major achievements the country has made since the 18th National Congress of the Communist Party of China in 2012 under Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.

Speaking about the documentary, Wei Tie, the director, says," The film arouses Chinese pride from deep inside."

The documentary focuses on key Chinese infrastructure（基础设施）projects in aerospace，high-speed rail，the Hong Kong-Zhuhai-Macao Bridge and the world's largest single-dish telescope FAST. The documentary also informs viewers that seven of the world's 10 biggest sea ports are now in China and that the country now has the longest high-speed rail network in the world.

In the film, Lin Ming, the chief engineer of the Hong Kong-Zhuhai-Macao Bridge project, says," In the past, what kind of projects we took up was decided by what kind of facilities we had. But, nowadays, no matter what kind of projects we are assigned, we develop the technology to complete it." His voice is calm but his words show the country’s self-confidence. Speaking of the importance of the new documentary for the Chinese, La Peikang, the head of China Film Corp, says," It's not only about showing the achievements, but presenting the present situation of China. The film will help people to know our country better."

Amazing China also focuses on common people. In the film, you see a young Tibetan woman volunteering in rural areas to help people get rid of poverty. And, you also see a successful entrepreneur from the coastal Fujian Province who settles in the Gobi Desert, in northwest China, who has taken up a new career growing grapes.

7 . As an educator and health care provider, I have worked with numerous children infected with the virus that causes AlDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, but I have especially learned that great courage can be found in the smallest of packages. Let me tell you about Tyler.

Tyler was born infected with HIV: his mother was also infected. From the very beginning of his life, he was dependent on medications to enable him to survive. When be was five, he had a tube inserted (插入) in a vein in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were linked to this pump and continuously supplied through this tube to his bloodstream. At times, he also needed supplemented(补充的) oxygen to support his breathing.

Tyler wasn’t willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon. All of us who knew Tyler were amazed at his pure joy in being alive and the energy it gave him. Tyler’s mom often teased him by telling him that he moved so fast that she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.

This dreaded disease eventually wore down even the likes of a little dynamo like Tyler. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became apparent that he wasn't going to survive, Tyler’s mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.

A few days before his death, Tyler called me over to his hospital bed and whispered,“might die soon. I’m not scared. When I die, please dress me in red. Mom promised she’s coming to heaven, too. I’ll be playing when she gets there, and I want to make sure she can find me.”

8 . When you are standing in front of fruit shelves in the supermarket, what is your attitude toward the imperfect tomatoes? Will you be blind to the ugly tomatoes without any hesitation and even throw them aside in disgust? Or will you put them in the shopping baskets without discrimination（歧视）? Most of you will bethe former.

Ugly produce is always left along the whole supply chain. After rounds of selection from farmers, packers and retailers, the annual percentage of eatable food waste is more than 30%（900,000 tons）before the produce arrives at shop shelves. These eatable wastes can feed over 2 million people per year. Besides, we also should not ignore the investment in the production process and the pollution caused by rot. For example, one-kilogram apple production consumes 822 litres of water. One ton of vegetables or fruits that are thrown away can produce around 800 litres of polluted water. And food transport is also a source of greenhouse gas.

Is there any great option to maximize farmer interests and reduce further losses? The answer is "YES". After Woolworth in Australia and Countdown in New Zealand introduced "The Odd Bunch", many retailers in America attempted to develop similar projects that could build a bridge between consumers and farmers, and offer ugly produce at more competitive prices. Through these projects, retail enterprises have built corporate reputation and gained confidence from the public. Farmers have significantly reduced the planting cost because of vast purchasing requirements from retailers. Consumers have enjoyed the similar taste at lower prices.

All the food is born equal, and all the food has the same right to be enjoyed. We shouldn't discriminate food through its uncommon looking. Life's "misery"（eg. exposure to the burning sun）will contribute to a more pleasant taste of food. Please value the unique appearance and qualities of these special foods!

9 . At age 12, Keegan Sobilo of New Baltimore carefully tucks his legs and arms into a fire suit, pulls on a helmet and climbs into a race car that exceeds 80 mph. He has been doing this since age 8.

"At first, I was scared to death. It was like, 'Let's do bowling or swimming.' It' s still very scary. But he knows what he's doing." said his mother.

"The sixth-grader always wears pajamas to the track every night and takes them off when he puts his race clothes on. He's been doing that for the last four years. That' s his trademark," said Tim Phillips, his crew chief. The first time he wore his train pajamas to the track, Keegan went from last place to ninth place. He decided they brought luck. Since then, he has won a series of championships.

Passion for cars runs in the family. Keegan' s father is a design mechanic at Fiat Chrysler Automobiles. He knows what it means to have seats and roll cages built to fit his son's body. "I tell my son you have to be the perfect package. Winning races every weekend is not the only key. More importantly, you have to have the right name, you have to look the correct way, speak the correct way, and act the correct way. Then the rest of it is really luck, like the stock market."

While Keegan' s classmates play basketball and volleyball, Keegan is at the Birch Run track—practicing, qualifying and racing until 10 pm or 2 am. While many children spend time playing video games, Keegan runs race simulation training with his joystick（操纵杆）after school.

"The kid is cool. It was like having a grandson. We showed respect to each other. And he takes it very seriously," said competitor Mike Todd, 69, of Galesburg, Michigan. "He's an older soul in a young man's body."

10 . Whales are big, but why aren't they even bigger? A new study says the key factor is how many calories they can take in. Researchers came to this conclusion after using small boats to chase down 300 whales of various species around the world. They reached out with long poles to attach sensors (传感器) to the creatures, allowing them to record what whales were doing as they dived for food.

The study included 90 blue whales, the biggest animals ever to live. Size estimates vary, but they can grow to about 100 feet long and weigh more than 100 tons, according to the American Cetacean Society. The research also included sperm whales, the biggest whales with teeth; they can grow to about 60 feet in length.

Toothed whales hunt their prey (猎物) one at a time, seeking them out in the dark depths with a sonar-like detection. But as their body size increases, their hunting style becomes progressively less efficient — they take in fewer calories from their meals than the number they burn in each dive. That's a result of the limited availability of prey.

Blue whales grow bigger because they feed in a much different and more efficient way, the researchers reported. They open their mouths wide to take in an enormous volume of water — even bigger than their body size — as they swim along. They then close their mouths and strain the water out through a sieve-like filter (过滤器), trapping huge numbers of tiny shrimp-like creatures called krill. That "allows them to take advantage of a very large prey resource that's very rich in a small amount of time," said Jeremy Goldbogen of Stanford University, another member of the research team. "They get a huge bang for the buck."

So why aren't they even bigger than they are? Perhaps blue whales are limited by the seasonal nature of the most nutritious krill patches, which grow huge and dense in the summer," Goldbogen said. "And calculations indicate that to sustain a blue whale that's 115 feet long, you'd need a density of prey that is just not seen anywhere in the world."
