　　There are 4 reading passages in this part. Each passage is followed by some questions of unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and then mark the corresponding letter on the Answer Sheet.Questions 41 to 45 are based on the following passage:

　　Each year, millions of people in Bangladesh drink ground water that has been polluted by naturally high levels of arsenic poison. Finding safe drinking water in that country can be a problem. However, International Development Enterprises has a low-cost answer. This non-governmental organization has developed technology to harvest rainwater.People around the world have been harvesting rainwater for centuries. It is a safe, dependable source of drinking water. Unlike ground water, rainwater contains no minerals or salts and is free of chemical treatments. Best of all, it is free.The rainwater harvesting system created by International Development Enterprises uses pipes to collect water from the tops of buildings. The pipes stretch from the tops of buildings to a two-meter tall storage tank made of metal. At the top of the tank is a so-called “first-flush”device made of wire screen. This barrier prevents dirt and leaves in the water from falling inside the tank.A fitted cover sits over the “first-flush” device. It protects the water inside the tank from evaporating. The cover also prevents mosquito insects from laying eggs in the water.Inside the tank is a low coat plastic bag that collects the water. The bag sits inside another plastic bag similar to those used to hold grains. The two bags are supported inside the metal tank. All total, the water storage system can hold up to three-thousand-five-hundred liters of water. International Development Enterprises says the inner bags may need to be replaced every two to three years. However, if the bags are not damaged by sunlight, they could last even longer.International Development Enterprises says the water harvesting system should be built on a raised structure to prevent insects from eating into it at the bottom. The total cost to build this rainwater harvesting system is about forty dollars. However, International Development Enterprises expects the price to drop over time. The group says one tank can provide a family of five with enough rainwater to survive a five-month dry season.

　　Questions 46 to 50 are based on the following passage:

　　Where one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible, for example by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basis of work in child clinics.The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them.Every parent watches eagerly the child's acquisition of each new skill―the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feeling of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself.Learning together is a fruit source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this co-operation. Building-block toys, jigsaw puzzles and crossword are good examples.Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters, others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.
