While engineers have made out fantastic products for sitting still--Munchery instead of walking to lunch, Uber instead of walking to the bus stop--services to make you move have been less appealing for consumers. Fitbit's stock price fell 18% after they announced their latest Apple Watch-like product named Fitbit Force. And new data suggests that, for the first time, death rates for large parts of the American population are rising, with signs pointing to inactivity and weight gain as the reasons. Our digital lifestyles and desk-based workplaces are contributing to serious health problems and could be shortening our lives, wellness firms want us to believe. Northrup, president and co-founder of the connected exercise device TAO-Wellness, was in Las Vegas to promote TAO's small device that encourages exercises. He lifts the device, about the size of an apple, and says workplaces should start encouraging on-site exercise. Nick Mokey, the managing editor of Digital Trends, agrees. "I hate to break it to you, a room full of people sitting down, but sitting is killing you," he says to the audience. They shift in their seats. In the health section of the Sands Exposition Hall, people are selling devices made by LifeSpan Fitness. They say they're the largest seller of treadmill desks in the US. At the center of their exhibition area is a Bike Desk, which looks like three gym bikes attached to a table. That's for people who just want to sit and enjoy conversation. Treadmill desk-related shame is their biggest obstacle, they say when LifeSpan installs two in opposite ends of the same building, neither tends to get used. If the company installs two next to each other, people will use them. "You don't want to be so noticeable, especially at work," company spokesman James Lowe says. What's more, what if we get sweaty using a treadmill in the office? What is the biggest problem with the treadmill desk? A) It takes up too much space. B) It is not comfortable to use C) It may cause awkwardness D) It will make employees tired

Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of"virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example.consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East, get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products The passage is most probably a _ . A) science news report B) book review C) newspaper advertisement D) science fiction story

My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still... We learn from the passage that the author would _ to prevent similar experience from happening again. A) write to the agency B) change her name C) avoid traveling abroad D) do nothing
