Some foods can make you sick if they are stored in conditions that are not cold enough to prevent the growth of harmful organisms. Freezing can keep some foods in good condition for months after the growing season. Yet foods can be damaged if they are kept too cold.

The British Development Group says the best time to prepare foods for storage is at harvest time while foods are still in the field.

Use a sharp knife and place the harvested items on a clean surface or directly into storage containers. Do not put them on the ground.

Use clean water to remove dirt, and keep the water clean. Usually it is better not to remove outer leaves from fruits and vegetables before storage. Without leaves, foods can become dry quickly.

Fruits and vegetables must cool from field heat before they are put into storage containers. Cooling them in water can spread funguses (霉菌) throughout the food. A better idea is to harvest foods either early or late in the day, and then leave them to cool naturally.

Some fruits and vegetables must be stored at zero to four degrees Celsius. Some foods need to be stored at four to eight degrees Celsius, and some need to be stored above eight degrees Celsius for best results.

Wet fruits and vegetables so they do not become too dry. The best time to do this is before storage. Cover the items in plastic once they reach the right temperature for storage. Most fruits and vegetables need the relative humidity (湿度). Finally, leave spaces between the food containers and the walls of the cold storage area so air can flow. Keep the spaces clean. And try not to open the doors too often.

64. The text is mainly about                 .

     A. the benefits of storing foods in cold conditions

     B. some tips for the storage of foods

     C. the research on some fruits and vegetables

     D. the process of keeping foods in good condition

65. What is the function of the leaves of fruits and vegetables?

     A. Keeping them from harmful organisms.               B. Helping keep them clean.

     C. Helping keep them fresh.                            D. Making them look more attractive.

66. Why is it better to harvest foods either early or late in the day?

     A. Because foods have no field heat then.

     B. Because it is easy to make them become cool from field heat naturally.

     C. Because foods then are wet enough to be stored.

     D. Because foods are cleaner then.

October 15th is Global Handwashing Day.  Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.
Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap. The goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps are equally effective at removing disease-causing germs （细菌）. They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Then, wash well under running water. Finally, dry your hands with a clean cloth.
The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases the chances that people will wash again.
It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea （痢疾）, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half.
【小题1】What does the author intend to tell us in the passage?

As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air ,It also collects bits of dust and microbes(微生物)that are floating in the air, When the rain reaches the ground it begins to pick up more dust and dirt, Many kinds of mineral substances dissolve in the water ,Sand and nud cannot dissolve in water.

Since water is so important to us, it is very important that the water we use should be clean , Otherwise, we might get some of the diseases that are carried by water Many microbes are harmful ,They are so small that we cannot see them ,These microbes must be removed or killed before the water is not clean, people who drink this water may get these diseases, Thus , to provide people with clean water, the government purifies the water.

Purification is a long process and consists of three stages: storing ,purifying and distributing ,The first stage is storing , Man-made lakes called reservoirs are used for this purpose ,Water from the rains ,other lakes, streams and rivers is collected in the reservoirs ,This water is usually dirty and muddy.

In the second stage shich is purifying , water from the reservoirs is filtered in a special pond, Stones, sand and other unwanted tiny things are caught in it, After that, tiny microbes are still present in the water ,These microbes are removed by “airing ”the water and by adding a chemical substance called chloring(氯)to the water ,This kills all the microbes in the water ,A fter this the water can be safely used for drinking.

The third stage is the distribution of the purified water to homes ,hospitals, offices ,factories and other places, This is done through a network of pipes of various sizes, These pipes must be make of a suitable material.
