专项训练八饮食、卫生与健康时间：8～10分钟/篇分值：2分/小题Passage 1(2018天津)Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plane. So airlines(航空公司) offer passengers food. But it is common that they feel bad about food taste. Do you agree?To solve this problem, airlines try hard to improve their food. They would like to do so because they don't want to lose customers.However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude(海拔) we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure(气压) reduces one third of the sensibility(感觉) of our taste buds(味蕾). So our taste buds become senseless. The sad fact, however, is that our noses don't know it.All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy(辛辣的) food. Without doing so, the food would be tasteless.Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste.Though scientists try their best, it is not as easy as they thought. Because they can't deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them.( )1.

What do students of your age eat for lunch at school in other countries?JapanHigh schools have dining rooms. They serve everything from noodles to rice, but not burgers and chips. Other children bring food from home, such as cold rice balls, meat or fish, pickles(泡菜)and vegetables. Twice a year parents are invited to have a taste of the food.United StatesA typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies. School lunches must also provide at least one third of the daily amount(总量)of necessary nutrition(营养)，such as, vitamin A, vitamin C and calcium(钙)．AustraliaMeat pies, sausage rolls(香肠卷)and hotdogs are all traditional dishes in Australian school shops. But as the country pays more attention to children's health, healthier foods have started to appear on school menus. Many schools have used a traffic light system. The sale of red labeled(标注)foods, including cookies, chocolate and soft drinks, is served only twice a week. Healthier green labeled foods such as sushi, sandwiches, corn and watermelons, however, are available every day.South AfricaMost of South African schools do not serve meals at all. Classes end at 1：30 p．m. and students get their own lunches. Many students bring food from home, usually sandwiches.Fast food and fried food sell the best among students. As a result, it has caused a rise in obesity(肥胖)among children.

A recent report shows that about80 percent of diseases in developing countries are caused by poor water and low sanitation(卫生)conditions. In those countries, women and girls spend several hours collecting water, but often polluted, far away from their families. The polluted water more or less influences their health. In this case, there is an urgent(迫切的) need for people in developing countries to have access to(有机会或权利使用) clean water to improve their health.Here is a short story about Hadjara Zakari, a 12­year­old girl in Niger. Having access to clean water changed her life. She learned about the importance of hand­washing when the school first received clean water three years ago. That evening, she told her father, “You shouldn't eat with me unless you clean your hands.” Her father was very angry and shouted at her, “It's not up to you to tell me what to do！” Stunned(目瞪口呆的), Hadjara sat in silence. But she knew she was right. In protest,_Hadjara refused to eat dinner that night. After her father questioned Hadjara's head teacher, he und erstood the importance of hand­washing and his daughter's intentions(目的). The girl really wanted her family to live longer and healthier lives.For people in developing countries, clean water can change many things, especially improve their health.
