Women's high participation in informal employment is partially due to the fact that many jobs in the formal economy are not opening to them: they are actively excluded of certain kinds of works or lack access to education and training or have domestic commitments.

R A B I D BATS O U T OF H E L L Gold diggers in Peru are being attacked by vampire bats. These are not ordinary vampire bats; these ones carry rabies. No (1) than 24 gold diggers from the town of Puerto Maldonado have died of rabies in the last three weeks, after (2) their blood sucked by vampire bats. A special team of bat-catchers and doctors armed with 11,000 rabies vaccines has been sent to the area to try to stop the epidemic (3) . The bats known locally as "vampires" have a wingspan (4) more than one metre. They fly into the gold diggers' huts after dark and attach (5) to the sleeping miners' heads, necks and feet. The bats' (6) are very small and the victim rarely wakes up. According to Dr. Hugo Arana, head of the anti-rabies unit in Lima. The bats also (7) an anticoagulant in their sahva which makes the blood flow more freely. This makes the imitation of the bite much (8) He says that normally vampire bats feed on animals (9) probably as a result of the rabies they simply look for the nearest living creature. Dr. Arana has plans to catch the bats by hanging nets between the trees. Meanwhile local priests are trying to persuade the miners (10) these attacks are not the work of evil spirits. C. Read the following passage and then answer the questions below. SLEEP We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating with some 16-17 hours' wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. 200
  18. The question is no mere academic one. The case, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls insistently for round- the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts arc changed every week; a person may work from 12 midnight to 8 a.m., one week, 8 a.m., to 4 p.m., the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently. One answer would seem to be longer periods on each shift, a month, or even three months. Recent research by Bonjer (1960) of the Netherlands, however, has shown that people on such systems will revert to their normal habits of sleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night work built up during the week. The only real solution appears to be to hand over the night shift to a corps of permanent night workers whose nocturnal wakefulness may persist through all weekends and holidays. An interesting study of the domestic hfe and health of night-shift workers was carried out by Brown in 1957. She found a high incidence of disturbed sleep, digestive disorder and domestic disruption among those on alternating day and night shifts, but no abnormal occurrence of these symptoms among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the strains of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his performance, but this can be laborious. Fortunately, we again have a physiological measure which correlates reasonably well with the behavioural one, in this case performance at various times of the day or night, and which is easier to take. This is the level of body temperature, as taken by an ordinary clinical thermometer. People engaged in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually reverse to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance and general alertness. Therefore by taking bodv temperature at intervals of two 201

So far, however, such a form of selection does not seem to have been applied in practice. From "Sleep and Dreams" by Robert Wilkinson Choose the best answer to each question. 1. The main theme of the passage is A. the effects of lack of sleep. B. sleep and body temperature. C. how easily people can get used to working at night. D. the effect of automation on working efficiency. 2. Why is the question "no mere academic one"? A. Because of research by Bonjer and Brown. B. Because sleep normally coincides with the hours of darkness. C. Because some people can change their sleeping habits easily. D. Because shift working in industry requires people to change their sleeping habits. 3. The main problem about night work is that A. people do not want the inconvenience of working on night shifts. B. people are disturbed by changing from day to night routines and bark. C. not all industries work at the same hours. D. it is difficult to fine a corps of good night workers. 4. The best answer to the problem seems to be A. not to change shifts from one week to the next B. to have longer periods on each shift. C. to employ people who will always work at night. D. to find ways of selecting people who adapt quickly. 5. Scientists are able to measure adaptation by taking body temperature because A. body temperature is a good basis for selection. B. people have low temperatures at night. C. the temperature reverses when the routine is changed. D. people have high temperatures when they are working efficiently. 6. "The third" (line 13) means A. the third week. B. the third shift. C. a third of the time. D. the third routine. 202
  20. 7. "Another" (Unc 14) means A. another routine. B. another shift. C. another week. D. another person. 8. "This latter system" (line 28) refers to A. Brown's research. B. spending a month or even three months on each shift. C. having the same people on night shift all the time. D. alternating day and night shifts. 9. "This" (line 32) refers to A. a person's performance. B. measuring a person's performance. C. the physiological measure. D. knowing when a person has adapted. 10. "This" (Une 35) refers to A. a physiological measure. B. performance at various times of the day or night. C. the level of body temperature. D. a person's performance.
