When he was seventy-five, he gave PS 12,000 to the village school to buy land and equipment   for a children's play ground. As a result of his kindness, many people came to visit him. Among them was a newspaperman, During their talk, Johnson remarked that he was seventy-five and expected to live to be a hundred. The newspaperman asked him how he managed to be healthy at seventy-five, Johnson had a sense of humor  . He liked whisky   and drank some each day. "I have an injection   in my neck each evening." He told the newspaperman, thinking of evening glass of whisky. The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was seventy-five and has a daily injection in his neck. Within a week Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection. The newspaperman  _  . A) should have reported what Johnson had told him. B) shouldn't have asked Johnson what injection he had. C) was eager to live a long life. D) should have found out what Johnson really meant.

Most kids hate to see their summer end, perhaps none more than the Murset children. This summer, the Murset family decided to travel across the country to help families in need, which proved to be a wonderful experience. People. comreported that Gregg Murset and his wife, Kami, decided to take their six children, ranging from 7 to 16 years old, from their home in Phoenix, Arizona, across the country to spend 20 days on the road to help 25 families in need. "I told the kids and my wife over breakfast that I wanted to do this," Gregg Murset, 40, told People. com. "They all looked at me like I was crazy," he said, "but when we started to read the stories of people we were going to help, their attitudes completely changed." Through Gregg's company, he was able to be matched with groups such as Autism Speaks, the Leukemia & Lymphoma Society, and others that connected the Mursets to families with children who have cancer and other serious illnesses. "When you have a kid who is struggling, the last thing you're thinking of is cleaning the house," says Gregg. The family traveled to many cities in their journey, including Albuquerque, Denver, Kansas City, Chicago, and Buffalo. The trip covered 6,500 miles. "It's been amazing to watch my own children open their eyes and see that the world is bigger than they think," he said. "Even the little kids are learning from this experience." And the families they've helped feel blessed to have met them. "They showed up at 8 a.m. and we had a list of things we needed help with," said Jim Spencer, a 61-year-old father in Warren, Michigan, whose 12-year-old daughter, Lexi, was diagnosed  with cancer a couple of years ago. The Mursets also used their travels as an opportunity to visit areas they had never been to, including the Statue of Liberty. But for Gregg, the main purpose of the trip was to teach his children to show concern for the happiness of other people rather than for themselves. "There is nothing wrong with your kid getting off the sofa, doing some work and sweating,"... During the trip, Gregg most wanted his kids to   _  . A) increase physical exercise B) gain more geography knowledge C) learn to be concerned about others D) improve their communication skills

If you've ever seen the way dog people interacted with their pets, it comes as no surprise that there's some germ-exchanging going on there. A new study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes live on your skin. A team of researchers led by Se Jin Song at the University of Colorado, Boulder, took swabs  of the tongues, palms, forehead and feces  of members of 60 family households. Some of the families had children or household pets and some did not; dogs were the only pets swabbed. Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly, family members who lived together had more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households, probably because we pass microbes through the air, through direct contact, and via the surfaces we touch. The most surprising finding, however, was the large bacteria contribution Fidonad made. The skin bacteria of dog owners from different households was almost as similar as if they'd cohabited without a dog. Put another way, you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does. The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human skin. One in particular, a family of bacteria called Methylophilaceae, was abundant in the mouths of dogs sampled as well as the skin of their owners--indicating "a common occurrence of oral-skin transfer between dogs and their owners," according to the results published in the journal eLife. What does this passage mainly tell us? A) It is unsafe to keep dogs because of microbes. B) How many kinds of bacteria live on people's skin because of dog ownership. C) Dog ownership affects the kinds of microbes living on people's skin. D) What are the similarities between people who keep dogs and those who don't.
