why didn't people wash in those days long ago？
Well, they did not have water in their house. They carried water from rivers or from holes in the ground (= wells). Towns people bought it from a water--carrier. Sometimes it was expensive; and soap was always expensive. They drank water, of course; and so they were clean inside. They did not think about the outside! And this is true; they just did not like a bath.
Modern life is different. We use a lot of soap and water. And we are all quite clean. However, a few people use too much soap; and they often get ill. Who are these people？
Many young women work as hairdressers. They wash and then "dress" other women's hair. That is their job, and they like it. Young hairdressers sometimes wash dirty heads on a busy day! Their hands are soapy for seven or eight hours; and that is not a good thing. A young hairdresser's hands are often red and ugly; and she must then go to doctor.
Long ago, people ______.
A．often died young
B．did not often have a bath
C．washed every day
D．washed every day and died young

Section B
Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文： Everywhere, water use is increasing. Humans already use fifty-four percent of all the fresh water in rivers, lakes and underground. There are some estimates that this rate will reach seventy percent by 2025.
Fresh water is necessary for life on the Earth. People need water for everyday activities and to produce food. Water is also important for energy production and the health of the Earth's environmental systems.
The United Nations is organizing a series of events to increase concern about water issues. UN officials have declared 2003 the International Year of Fresh Water. A goal of the campaign is to build support for policies to use water more wisely.
Another goal is to get more people to use water in ways that will not hurt the environment. The world population exceeds six thousand million. More than one thousand million lack safe drinking water. More than two thousand million suffer from diseases linked to dirty water. And, more than two thousand million live without waste-treatment systems.
Water was one of the issues discussed at the UN Millennium Summit two years ago. Leaders said they would work to cut the number of people without safe drinking water in half by 2015. Officials renewed that goal last year at the Summit on Sustainable Development, in Johannesburg, South Africa. They also promised to cut in half the number of people without safe systems to treat waste by 2015.
