Unit 5 The power of nature
Environmental health is defined as the control of the factors (因素)in the environment social well-being (安乐) that may have harmful effects on people's physical, mental, or because natural disasters expose people to danger by bringing up or threatening their immediate environment , effective management of environmental health after a natural disaster is of great importance.
The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution (分配)of safe and accessible water, and the protection and distribution of safe food products and so on.
To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster's specific effects as quickly as possible.
This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The recommended environmental health measures have been listed in the order of priority in which they should be taring an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure.

A. Victims may be in danger without immediate controls.
B. Victims may be at the risk of losing their properties.
C. Victims may be exposed to poisonous or radioactive minerals.
D. Victims may be threatened by environmental health problems.

说明文 简单易行的太阳能蒸馏器 316 ★★★☆☆ 6分钟
A build-it-yourself solar still（蒸馏器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5＇ 5＇ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container — perhaps just a drinp — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.
To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.
Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.
The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.
32. What do we know about the solar still equipment from the first paragraph?
A. It’s delicate. B. It’s expensive.
C. It’s complex. D. It’s portable.
33. What does the underlined phrase “the water catcher” in paragraph 2 refer to?
A. The tube. B. The still.
C. The hole. D. The cup.
34. What’s the last step of constructing a working solar still?
A. Dig a hole of a certain size. B. Put the cup in place.
C. Weight the sheet’s center down. D. Cover the hole with the plastic sheet.
35. When a solar still works, drops of water come into the cup from .
A. the plastic tube B. outside the hole
C. the open air D. beneath the sheet
