问题     Here’s more proof that most people have habits that aren’t very healthful— and sometimes can be plain disgusting.
    For a study, medical students secretly watched hundreds of people cough or sneeze at a train station, a shopping mall and a hospital in New Zealand. What they saw wasn’t pretty, with most people failing to properly prevent an explosion of infectious germs in air. The work was done in the capital city of Wellington over two weeks last August, at the tail end of a worrisome but fairly mild wave of swine flu illnesses. It was a time when the pandemic (流行病) was international news, and public health campaigns were telling children and adults to be careful about spreading the virus.
    The good news is that about three of every four people tried to cover their cough or sneeze, in at least a token attempt to prevent germs from flying through the air. The bad news is that most people—about two of three—used their hands to do it. "When you cough into your hands, you cover your hand in virus," said study author Nick Wilson, an associate professor of public health at the Otago University campus in Wellington. "Then you touch doorknobs, furniture and other things. And other people touch those and get viruses that way," he explained. Health officials recommend that people sneeze into their elbow, in a move sometimes called "the Dracula" for its resemblance to a vampire (吸血鬼) suddenly drawing up his cape. But only about 1 in 77 did that. Using a tissue or handkerchief is another preferred option, but only about 1 in 30 did that.
    More bad news: The researchers didn’t report numbers on this, but several times they saw people spat on the floor, including at the hospital. "They were a bit grossed out," Wilson said, describing the reaction of his team, which logged 384 sneezes and coughs. Wilson called the findings surprising, especially given that it occurred only four months after the virus was first identified, when it was still considered unusually dangerous. The study was presented Monday at an infectious diseases conference in Atlanta.
    Coughing into hands might be fine if everyone promptly and thoroughly disinfected (消毒) their hands afterward, but no one believes that’s happening. A 2007 study by Harris Interactive done in public restrooms suggested that about one in four people don’t even wash their hands after going to the bathroom. It found that men were the worst, with one out of three failing to wash up.
The disgusting behavior made by a few people and grossed Wilson’s team out is to______.
选项
答案spit on the floor
解析 同义转述题。本题考查让Wilson的研究小组感觉恶心反胃的行为。定位句提到，研究人员有好几次看到人们随地吐痰，即便是在医院里也这样做。正是这种行为让人反胃。由空格前的不定式符号to不难看出系动词is后面是不定式结构作表语，应该用动词原形，所以答案是spit on the floor。
