问题     Read the texts from a magazine article in which five health experts talked about water. For questions 61 to 65, match the name of each expert (61 to 65) to each of the statements (A to G) given below. Mark your answers on your answer sheet.
★Evans, Caradoc:
It is a substance that is essential to all known forms of life in its pure form. Water is abundant on Earth. It exists in many places and forms. It appears mostly in the oceans and polar ice caps, but also as clouds, rain water, rivers, freshwater aquifers, and sea ice. On the planet, water is continuously moving through the cycle involving evaporation, precipitation, and runoff to the sea.
★David John:
    Water fit for human consumption is called potable water. This natural resource is becoming scarcer in certain places as human population in those places increases, and its availability is a major social and economic concern. Drinking water is water that is intended to be drunk by humans. Water of sufficient quality to serve as drinking water is called potable water whether it is used as such or not. Although most fresh water sources are drinkable by humans, they can be a disease vector or cause long-term health problems if they do not meet certain water quality guidelines.
★Strong, Alex:
    Most nations have water quality regulations for water sold as drinking water, although these are often not strictly enforced outside of the developed world. Virtually all municipal water systems deliver a single quality of water, whether it is to be used for drinking, washing or landscape irrigation. In the United States, public drinking water is ruled by the Safe Drinking Water Act (SDWA). Among other provisions, it protects the right of employees to report potential violence. Within 30 days of any retaliation, a whistleblower can file a complaint with the Occupational Safety and Health Administration (OSHA).
★Garland, Judy:
    So far as bacterial is concerned, the usual test is for a count of (more often than not harmless) bacteria, it being assumed that these serve as an indication of water pollution. Water purification is the removal of contaminants from raw water to produce drinking water that is pure enough for humans. Many contaminants can be dangerous but depending on the quality standards, others are removed to improve the water’s smell, taste, and appearance.
★Vincent, J. W.:
    It is not possible to tell whether water is safe to drink just by looking at it. Simple procedures such as boiling are not sufficient for treating water from an unknown source. Even natural spring water-considered safe for all practical purposes in the 1800’s--must now be tested before determining what kind of treatment is needed.
    Now match each of the experts (61 to 65) to the appropriate statement. Note: there are two extra statements.

A. Not all water is suitable for people to drink; only a small proportion is.
B. Bottled water may not be a good choice for people to drink.
C. Regulations for drinkable water vary from country to country.
D. Pollution is a big threat to the safety of drinkable water.
E. Water should be processed before they could be consumed by human.
F. This is the basic knowledge you need to know about water.
G. Criteria for safe water change with time.
