People in theUSthought Ebola was only a disease, accompanied with fever and found inAfricaat the beginning.  (1)  then a man from west Africa died from Ebola at a hospital in Dallas, Texas. And two nurses   (2)   for him became infected(感染) with the virus, which made the US government publish new guidelines to   (3)   health workers．

Top American  (4)  have repeatedly said that most people have little chance of being infected．Experts have  (5)   that Ebola can only be spread through infected person’s body fluids — like blood．But it   (6)   many Americans are  (7)  what they have heard．

A recent survey found more than 80 percent of Americans believe that Ebola can be spread in many   (8)  , including air forced through the nose or mouth. The Harvard School of Public Health   (9)   the findings. The study also showed that most adults fear there will be a(n)  (10)  of Ebola in the United States soon.

  (11)   survey found that more than 70 percent of Americans would support calls to   (12)   travel to and from Ebola-affected parts ofAfrica.

Thomas Frieden heads the U.S．Centers for Disease Control and Prevention．When asked whether   (13)   officials had considered a travel ban, Mr．Frieden had  (14)    to say：“We won’t be able to check travelers for   (15)  when they leave or when they arrive. We won’t be able, as we do   (16)  , to take a detailed history to see if they were   (17)   when they arrive. When they   (18)   , we wouldn’t be able to impose quarantine（强加隔离）as we now can if they have high-risk touch.”

Last week, President Barack Obama urged Americans not to   (19)   what he called “ panic or fear ”.

This week，the administration announced that all travelers reaching the United States from some African nations are  (20)   to pass through one of five airports.

Whenever Michael Carl goes out to dinner with friends, he plays something called the “phone stack” game: Everyone   (1)   their phones in the middle of the table; whoever looks at their device before the check arrives   (2)   for dinner.

Brandon Holley had trouble   (3)   her mobile phone when she got home from work. So about six months ago, she   (4)   putting her phone into a milk tin the moment she walked in. It remains there until after dinner. And Mare Jacobs, a fashion designer, didn’t   (5)   to sleep close to a beeping gadget. So he   (6)  digital devices from his bedroom — a house rule he   (7)   with audiences during a recent screening of Disconnect.

As smart phones   (8)   to make their way into our lives, and wearable devices like Google Glass   (9)   to destroy our personal space even further, overtaxed users are carving out their own device-free zones. Whether it’s a physical   (10)   (no ipads at the dinner table) or a conceptual one (turn off devices by 11 p.m.), users say these disconnecting   (11)   are improving their relationships.

“Disconnecting is a luxury that we all   (12)  ,” said Lesley, a writer who keeps her phone away from the dinner table at home. “The expectation that we must always be   (13)   to employers, colleagues and family creates a real problem in trying to   (14)   private time. But that private time is more important than ever.”

A popular method for disconnecting is to choose a box for your cellphone, like the milk tin that Ms. Holley uses. “  (15)   my phone is buzzing or lighting up, it’s still a distraction, so it   (16)   in the box.” said Ms. Holley. Others choose new   (17)  . “No screens after 11 p.m.” said Ari. Melber, a TV host. “Now evenings are more   (18)  and I am sleeping better.” he added.

  “My friends made   (4)   about me for being fat sometimes,” he said. “But this is more about myself. It’s hard to find a   (5)  , and it’s not good for my   (6)  .”

  Around one in five people are   (7)  or obese in China--more than 250 million people. It’s an   (8)  result of the country’s rapid economic development which has   (9)   a more sedentary (久坐的)lifestyle for many. World Healthy Organization’s China representative Dr Hans Troedsson agrees. “ With unhealthy diets and less   (10)  exercise, it creates this almost boom of obesity that we see in China today,” Troedsson said.

  The staff at the Aimin Weight loss Clinic keeps a   (11)   eye on exercise and diet. They tell He to eat less fatty food and more regulated portions.

  “ When I first came I was really   (12)  , but after a couple of weeks I got   (13)   to it. Now I eat less than the others because I have higher   (14)   for myself, and I want to   (15)   weight faster,” he said.

With diabetes and hypertension(高血压) on the   (16)   , the WHO   (17)   lifestyle diseases are becoming a   (18)   issue for this national’s healthcare system.

 China’s health officials say they want more people to follow in He’s steps and   (19)   up. If    (20)  , they fear millions of people will develop long term health problems, costing China billions of dollars and reversing some of the country’s economic gains of the last three decades.
