【正确答案】 D
【答案解析】[听力原文] 26-28 A mother in Tamil Nadu, India, recently had a question for our new series on children and parenting. This woman in Tuticorin has a son who is almost three years old. He attends a pre-kindergarten school. (26) {{U}}She wonders why he often suffers from a blocked or leaky nose and a cough.{{/U}} Along with these, he gets a temperature of thirty-eight and three-tenths degrees Celsius. Children can come in contact with all sorts of bacteria, viruses and other organisms as they share toys, toilets and towels. Some will make them sick, others are harmless. (27) {{U}}Good hand washing is an important way to reduce the spread of infections{{/U}}. Caregivers should also be trained in ways to clean, sanitize and disinfect. The Web site for the National Resource Center for Health and Safety in Child Care explains the differences. This government-financed center says parents should look around child care centers. Make sure toys, furniture and other equipment are clean and in good condition. Not only that, ask how often things get cleaned—there should be an established program. The experts in Colorado say parents should not take sick children to day care if they might infect others. They also advise child care operators to keep a sick child away from healthy children whenever possible. Being in a "germ factory" is not necessarily all bad. (28) {{U}}Some experts believe that children exposed early to common germs develop a greater resistance to them when they reach school age{{/U}}. 26. What does the son suffer from? [一点即通] 从文章一开头就提到了一位母亲对自己儿子的病症的描述,a blocked or leaky nose and a cough,很明显,包括了A)、B)、C)三个选项中的症状,故选D)项。 [未听先知] 根据选项中的a blocked or leaky nose,cough,infections,children等信息,可以推断本短文可能与孩子患病,预防,治疗等有关。
【正确答案】 B
【答案解析】[听力原文] Why is good hand washing important? [一点即通] 短文中在提到给儿童监护者的意见时,就开门见山地说道了好的洗手习惯是减少感染的传播的重要手段。所以好的习惯之所以重要就是因为可以减少感染(Good hand washing is an important way to reduce the spread of infections)。故选B)项。
【正确答案】 A
【答案解析】[听力原文] According to some experts what's the benefit for children exposed early to common germs? [一点即通] 该题的关键在抓住not all这种否定式的存在,并注意最后一段的特殊性。整篇文章都在讲述如何减少病菌的入侵,但在最后一段却提到了儿童提前在germ factory中的一个好处。故选A)项。
