A solar pump(太阳能水泵 ) was built in a desert small village. The pump used the deserts most common resource – sunlight, to increase its greatest need, water. Solar collectors were used to collect the sun’s rays. Flat collectors were used instead of concave (凹的) collectors. Flat collectors can be still and do not have moving parts, which can be broken in sandstorms. The system used the 20C temperature difference between the solar collectors and the ground water to work a steam engine which pumped water from under the ground.
Some of the social effects of the new pump were planed for. Children aged 6—15 used to meet the old men to receive the informal education there. In order to replace this, a school was also included in the project. But the project had not considered the traditional power structure of the village. As soon as the foreign experts left, the two richest men in the village took control of the pump and started selling water to everyone else. The result was that the majority of the people were poorer than before.
16. The basic function of the solar collectors is to ______
A. pump water           B. gather the sun’s rays 
C. start engine            D. raise the temperature
17. According to the passage which of the following statements could be true?
A. Solar collectors were concave collectors               
B. Flat collectors can be broken in sandstorms.
C. Concave collectors may be have moving parts.     
D. A solar pump is a solar collectors.
18. The underground water is pumped by means of ______.
A. solar collectors  B. the 20C temperature difference C. the system  D. a steam engine
19. Another plan was also included that_____.
A. some new pumps were to built ,too
B. children from aged 6—15 were required to meet old men.
C. a new school would take the place of the informal education.
D. the richest men in the village would control the pump.
20. From this passage , it can be inferred that_____.
A. the project was good , but people there disliked it.
B. only few rich men supported the project.
C. the project was successful even though it only brought good social effects to fewer villagers.
D. the project was a complete failure, because the result was against its purpose.

Another small animal that tigers eat in Ranthambhore （a wildlife park in northern India） is the porcupine （豪猪）．These animals are spread widely across India in open areas and grasslands; they often live in the earth and between rocks．They are good diggers, and in Ranthambhore are nocturnal （夜出的）; they only come out at night．They weigh 12 to 16 kilograms and reach the length of 80 to 90 centimetres．They live usually on vegetables and fruit and seem to have a good sense of smell．Porcupines defend themselves when attacked by moving backwards with their quills upright, often making a strange noise．
Several times, I have found the remains of quills where a tiger has killed and eaten a porcupine, but I have never actually seen the kill．In spite of the quills, experienced tigers will try to kill clearly by biting the porcupine’s head, its weakest spot．But the quills are very sharp and can give painful injuries to young tigers．If the quills have gone in very deeply or if they are stuck in the tiger’s paw, it will try to pull them out．Often, it will be successful, and the wound will get better．But, if the quills have gone in very deeply or if they are stuck in the tiger’s neck or mouth, where they cannot be reached, the wound will often turn bad．If this happens, the tiger is in pain and is less able to hunt animals．It has to look for easier prey and so may turn to cows on the edges of the forest．From this, it is a small step to becoming a man-eater．
【小题1】 A porcupine is a small animal which _____．
