【推荐1】Holding the large and heavy “brick” cellphone he’s credited with inventing 50 years ago,Martin Cooper talks about the future.

Little did he know when he made the first call on a New York City street from a heavy Motorola prototype(原型)that our world would come to be encapsulated on a sleek glass sheath where we search，connect,like and buy.

Cooper says he is an optimist. He believes that advances in mobile technology will continue to transform lives but he is worried about risks smartphones pose to privacy and young people.

“My most negative opinion is we don’t have any privacy anymore because everything about us is now recorded someplace and accessible to somebody who has enough intense desire to get it,” the 94-year-old said in an interview in Barcelona at MWC, the Mobile World Congress, the world’s biggest wireless trade show, where he was getting a lifetime award.

Cooper sees a dark side to the advances, including the risk to children. One idea, he said, is to have“various Internets intended for different audiences.”

Cooper made the first public call from a handheld portable telephone on a Manhattan street on April 3,1973,using a prototype device his team at Motorola had started designing just five months earlier.

Cooper used the Dyna-TAC phone to famously call his opponent at Bell Labs, owned by AT&T. It was literally the world’s first brick phone,weighing 2.5 pounds and measuring 11 inches.

The call helped kick-start the cellphone revolution (革命).

Cooper said he’s “not crazy” about the shape of modern smartphones. He thinks they will develop so that they’ll be “distributed on your body,” possibly as sensors“measuring your health at all times.”

Batteries, he said, might be replaced by human energy.The body makes energy from food,he argues, so it could possibly also power a phone.Instead of holding the phone in the hand, for example, the device could be placed under the skin.

Because of the way living things rely on each other, noise pollution may actually stop some forests from growing, a new study suggests. In a New Mexico woodland of pine trees, researchers found far fewer tree seedlings (小苗) in noisy sites than they did in quiet ones.

The study area is dotted with gas wells, some of which are quiet and some of which have compressors (压缩机) that create a constant noise. This allowed Jennifer Phillips, a behavioral ecologist at Texas A&M University-San Antonio and her colleagues to compare sites that were similar except for noise level. In areas that had been noisy for at least 15 years, the researchers found only about 13 pine seedlings, compared with 55 pine seedlings per hectare (公顷) in quiet areas.

The differences in plant growth were probably caused by changes in animal behavior, said Phillips. For example, noise might drive away certain pollinators (传粉昆虫) such as bees, bats and moths. In the case of pine trees, the problem was likely a lack of animals to disperse seeds. Pines depend on birds to carry their seeds away from the parent tree, and birds are known to avoid noise. The differences between the sites aren’t yet obvious to someone walking through them, said Sarah Termondt, a botanist (植物学家) with the U.S. Fish and Wildlife Service who helped conduct the study. That’s probably because pines are slow-growing, with most of the mature trees in such woodlands being over a century old.

The study raises questions about the future of the area. “If the noise stays there long term, are we going to lose this important ecosystem of the pine which supports so much wildlife?” said Phillips. The study was published today in the journal Proceedings of the Royal Society.

But first he explained he was a very heavy sleeper,“I may possibly protest(抗议)loudly when you try to wake me up,” he said to the conductor.“But don’t take any notice of what I say.Just put me off the train anyway.”

Then Mark Twain went to sleep.Later,when he woke up it was night time and the train had reached Paris already.He realized at once that the conductor had forgotten to wake him up at Dijon.He was so angry that he ran to the conductor and began to shout at him.

“I have never been so angry in my life,” Mark Twain said.

The conductor looked at him calmly(平静地).“You are not half so angry as the American whom I put off the train at Dijon,” he said.

Trevor, the son of a Xhosa (科萨人) mother and a Swiss-German father, was born a crime as it was illegal for different races to marry and have children in Africa. Growing up biracial in the post-apartheid era (后种族隔离时代), his mother is an influential partner at every step along his journey. She worked diligently to stay out of poverty and keep Noah in good schools. Trevor’s mom stressed independence and free thought as well as all the values of Judaism (犹太教). Even before they knew apartheid would end, she wanted him to live freely. She took him to places that black South Africans considered “white things,” like ice rinks and the suburbs, because even if he never left the ghetto (贫民区), he would know that the ghetto was not the world. It was her mother’s aim to keep him from internalizing his oppression, and to convince him that he was greater than social labels. His mom would take him to the library and museums, and local college campuses. For his mother, being a black woman didn’t mean he couldn’t achieve greatness. She gave him permission to dream beyond his circumstances.

In Trevor’s whole early life, being mixed-race, he often wasn’t allowed to go outside during apartheid because the police could have taken him away; he couldn’t be seen with his parents and his mother had to pretend to be his maid when they were in public. So, Trevor had to have his mother’s friends pose as his mother. Trevor struggled to fit in at school as he didn’t know which group to play with. Later in high school, Trevor had to start a lunch delivery business to move up and be accepted by his fellow classmates. After high school, he started getting into comedy in 2002 and has been on TV ever since. Trevor had a rough, but loving relationship with his mother as he was always getting in trouble. Trevor didn’t see his dad much and could only meet in secret. In the end, Born a Crime is not just an unnerving account of growing up in South Africa under apartheid, but a love letter to the author’s remarkable mother. Noah writes: “I understood even from an early age that we weren’t just mother and son. We were a team.”

Born a Crime tells a really personal and yet universal story in many respects. It is undoubtedly a life-changing story which is powerful, honest, funny and dark at the same time, still it never turns to despair, self-pity or hopelessness. It’s a story of survival against the odds and the human ability to transcend the limits of their origin. At the end of the book, he explains this miracle that happened to his mother, where she survives a bullet to the head. These stories uncover new feelings towards loved-ones, and may influence you to sincerely reconsider connections to your family and their priorities.
