IELTS READING – Let’s Go Bats – S37AT1

IELTS Reading Let’s Go Bats reading practice test has 10 questions belongs to 🦇 Animal Biology & Science subject..

A. Bats have a problem: how to find their way around in the dark they hunt at flight, and cannot use light to help them find prey and avoid obstacles. You might say that this is a problem of their own making one that they could avoid simply by changing their habits and hunting by day. But the daytime economy is already heavily exploited by other creatures such as birds. Given that there is a living to be made at night, and given that alternative daytime trades are thoroughly occupied, Q3 natural selection has favored bats that make a go of the night-hunting trade. It is probable that the nocturnal trades go way back in the ancestry of all mammals. In the time when the dinosaurs. dominated the daytime economy, our mammalian ancestors probably only managed to survive at all Q2 because they found ways of scraping a living at night. Only after the my stenos mass extinction of the dinosaurs about 65 million years ago were our ancestors able to emerge into the daylight in any substantial numbers.

 

B. Bats have an engineering problem: how to find their way and find their prey in the absence of light Bats are not the only creatures to face this difficulty today. Obviously, the night-flying insects that they prey on must find their way about somehow. Q1 Deep-sea fish and whales have little or no light by day or by night. Q1 Fish and dolphins that live in extremely muddy water cannot see because, although there is light, it is obstructed and scattered by the dirt in the water Q1 Plenty” of other modern animals make their living in conditions where seeing is difficult or impossible.

C. Given the questions of how to manoeuvre in the dark, what solutions might an engineer consider? The first one that might occur to him is to manufacture light, to use a lantern or a searchlight Fireflies and some fish (usually with the help of bacteria) have the power to – manufacture their own light but the process seems to consume a large amount of energy. Fireflies use their light for attracting mates. This doesn’t require a prohibitive amount of energy: a male’s tiny pinprick of light can be seen by a female from some distance on a dark night since her eyes are exposed directly to the light source itself. However, using light to find one’s own way around requires vastly more energy, since the eyes have to detect the tiny fraction of the light that bounces off each part of the scene. The light source must, therefore, be immensely brighter if it is to be used as a headlight to illuminate the path, than if it is to be used as a signal to others. In any event, whether or not the reason is the energy expense, it seems to be the case that with the possible exception of some weird deep-sea fish, no animal apart from man uses manufactured light to find its way about

D. What else might the engineer think off Well, blind humans sometimes seem to have an uncanny sense of obstacles in their path, it has been given the name’ facial vision’, because blind people have reported that Ft feels a bit like the sense of touch, on the face. One report tells of a totally blind boy who could and his tricycle at good speed round the block near his home, using facial vision. Experiments showed that, in fact, facial vision is nothing to do with touch or the front of the face, although the sensation may be referred to the front of the face, like the referred pain in a Q6 phantom limb The sensation of facial vision, it turns out really goes in through the ears.

Blind people, without even being aware of the fact are actually using Q7 echoes of their own footsteps and of other sounds, to sense the presence of obstacles. Before this was discovered, engineers had already built instruments to exploit the principle, for example, to measure the Q8 depth of the sea under a ship. Q5 After this technique had been invented, it was only a matter of time before weapons designers adapted ft for the detection of Q9 submarines. Both sides in the Second World War relied heavily on these devices, under such code names as Asdic (British) and Sonar (American), as well as Radar (American) or RDF (British), which uses radio echoes rather than sound echoes.

E. The Sonar and Radar pioneers Didn’t know it then, but all the world now knows that bats, or rather Q10 natural selection working on bats, had perfected the system tens of millions of years earlier, and their radar’” achieves feats of detection and navigation that would strike an engineer dumb with admiration It is technically incorrect to talk about bat’radar1, since they do not use Q11 radio waves. It is sonar. But the underlying Q12 mathematical theories of radar and sonar are very similar, and much of our scientific understanding of the details of what bats are doing has come from applying radar theory to them. The American Q13 zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term ‘echolocation’ to cover both sonar and radar, whether used’ by animals or by human instruments.

IELTS READING – Persistent bullying is one of the worst experiences a child can face S36AT3

IELTS Reading Persistent bullying is one of the worst experiences a child can face reading practice test has 10 questions belongs to 🧠 Child Psychology & Education subject..

Peter Smith, Professor of Psychology at the University of Sheffield, directed the Sheffield Anti-Bullying Intervention Project, funded by the Department for Education.

Here he reports on his findings.

A. Bullying can take a variety of forms, from the verbal – being taunted or called hurtful names – to the physical – being kicked or shoved – as well as indirect forms, such as being excluded from social groups. Q27 A survey I conducted with Irene Whitney found that in British primary schools up to a quarter of pupils reported experience of bullying, which in about one in ten cases was persistent. Q31 There was less bullying in secondary schools, with about one in twenty-five suffering persistent bullying, but these cases may be particularly recalcitrant.

B. Q28 Bullying is clearly unpleasant and can make the child experiencing it feel unworthy and depressed. In extreme cases it can even lead to suicide, though this is thankfully rare. Q32 Victimised pupils are more likely to experience difficulties with interpersonal relationships as adults, while children who persistently bully are more likely to grow up to be physically violent, and convicted of anti-social offences.

C. Q33 Until recently, not much was known about the topic, and little help was available to teachers to deal with bullying. Q29 Perhaps as a consequence, schools would often deny the problem. ‘There is no bullying at this school’ has been a common refrain, almost certainly untrue. Fortunately more schools are now saying: There is not much bullying here, but when it occurs we have a clear policy for dealing with it.’

D. Q30 Three factors are involved in this change. First is an awareness of the severity of the problem. Second, a number of resources to help tackle bullying have become available in Britain. For example, the Scottish Council for Research in Education produced a package of materials, Action Against Bullying, circulated to all schools in England and Wales as well as in Scotland in summer 1992, with a second pack, Supporting Schools Against Bullying, produced the following year. In Ireland, Guidelines on Countering Bullying Behaviour in Post-Primary Schools was published in 1993. Third, there is evidence that these materials work, and that schools can achieve something. This comes from carefully conducted ‘before and after’ evaluations of interventions in schools, monitored by a research team. Q34 In Norway, after an intervention campaign was introduced nationally, an evaluation of forty-two schools suggested that, over a two-year period, bullying was halved. The Sheffield investigation, which involved sixteen primary schools and seven secondary schools, Q30 found that most schools succeeded in reducing bullying.

E. Q35 Evidence suggests that a key step is to develop a policy on bullying, saying clearly Q36 what is meant by bullying, and giving explicit guidelines on what will be done if it occurs, what records will be kept, who will be informed, what sanctions will be employed. The policy should be developed through consultation, over a period of time – not just imposed from the head teacher’s office! Pupils, parents and staff should feel they have been involved in the policy, which needs to be disseminated and implemented effectively.

Other actions can be taken to back up the policy. Q37 There are ways of dealing with the topic through the curriculum, using video, drama and literature. These are useful for raising awareness, and can best be tied into early phases of development, while the school is starting to discuss the issue of bullying. They are also useful in renewing the policy for new pupils or revising it in the light of experience. But curriculum work alone may only have short-term effects; it should be an addition to policy work, not a substitute.

There are also ways of working with individual pupils, or in small groups. Q38 Assertiveness training for pupils who are liable to be victims is worthwhile, and certain approaches to group bullying such as ‘no blame’, can be useful in changing the behaviour of bullying pupils without confronting them directly, although other sanctions may be needed for those who continue with persistent bullying.

Work in the playground is important, too. Q39 One helpful step is to train lunchtime supervisors to distinguish bullying from playful fighting and help them break up conflicts. Another possibility is to improve the playground environment, so that pupils are less likely to be led into bullying from boredom or frustration.

F. With these developments, schools can expect that at least the most serious kinds of bullying can largely be prevented. The more effort put in and the wider the whole school involvement, the more substantial the results are likely to be. The reduction in bullying – and the consequent improvement in pupil happiness – is surely a worthwhile objective.

IELTS READING – Do literate women make better mothers? S36AT2

IELTS Reading Do literate women make better mothers? reading practice test has 10 questions belongs to 👩‍👧 Education / Public Health subject..

Q15 Children in developing countries are healthier and more likely to survive past the age of five when their mothers can read and write. Experts In public health accepted this idea decades ago, Q16 but until now no one has been able to show that a woman’s ability to read in Itself Improves her children’s chances of survival.

Most literate women learnt to read In primary school, and the fact that a woman has had an education may simply indicate her Q17 family’s wealth or that It values Its children more highly. Now a long-term study carried out In Nicaragua has eliminated these factors by showing that Q18 teaching reading to poor adult women, who would otherwise have remained Illiterate, has a direct effect on their children’s health and survival.

Q14 In 1979, the government of Nicaragua established a number of social programmes, including a National Literacy Crusade. By 1985, about 300,000 Illiterate adults from all over the country, many of whom had never attended primary school, had learnt how to read, write and use numbers.

During this period, researchers from the Liverpool School of Tropical Medicine, the Central American Institute of Health In Nicaragua, the National Autonomous University of Nicaragua and the Costa Rican Institute of Health Interviewed nearly 3,000 women, some of whom had learnt to read as children, some during the literacy crusade and some who had never learnt at all. The women were asked how many children they had given birth to and how many of them had died In Infancy. The research teams also examined the surviving children to find out how well-nourished they were.

The Investigators’ findings were striking. Q20 In the late 1970s, the infant mortality rate for the children of Illiterate mothers was around 110 deaths per thousand live births. At this point In their lives, those mothers who later went on to learn to read had a similar level Of child mortality (105/1000). For women educated in primary school, however, the Infant mortality rate was significantly lower, at 80 per thousand.

Q21 In 1985, after the National Literacy Crusade had ended, the infant mortality figures for those who remained illiterate and for those educated In primary school remained more or less unchanged. Q22&23 For those women who learnt to read through the campaign, the infant mortality rate was 84 per thousand, an impressive 21 points lower than for those women who were still Illiterate. The children of the newly-literate mothers were also better nourished than those of women who could not read.

Why are the children of literate mothers better off? According to Peter Sandiford of the Liverpool School of Tropical Medicine, no one Knows for certain. Child health was not on the curriculum during the women’s lessons, so fie and his colleagues are looking at other factors. They are working with the same group of 3,000 women, to try to find out whether reading mothers make better use of hospitals and clinics, opt for smaller families, exert more control at home, learn modern childcare techniques more quickly, or whether they merely have more respect for themselves and their children.

The Nicaraguan study may have important implications for governments and aid agencies that need to know where to direct their resources. Sandiford says that there is increasing evidence that female education, at any age, is “an important health intervention in its own right’. Q26 The results of the study lend support to the World Bank’s recommendation that education budgets in developing countries should be increased, not just to help their economies, but also to improve child health.

Q25 ‘We’ve known for a long time that maternal education is important,’ says John Cleland of the London School of Hygiene and Tropical Medicine. ‘But we thought that even if we started educating girls today, we’d have to wait a generation for the payoff. The Nicaraguan study suggests we may be able to bypass that.’

Cleland warns that the Nicaraguan crusade was special in many ways, and similar campaigns elsewhere might not work as well. It is notoriously difficult to teach adults skills that do not have an immediate impact on their everyday lives, and many literacy campaigns in other countries have been much less successful. ‘The crusade was part of a larger effort to bring a better life to the people,’ says Cleland. Replicating these conditions in other countries will be a major challenge for development workers.

IELTS READING – Doctoring sales S36AT1

 IELTS Reading Doctoring sales reading practice test has 10 questions belongs to Business & Ethics subject..

Pharmaceuticals is one of the most profitable industries in North America. But do the drugs industry’s sales and marketing strategies go too far?

A. A few months ago Kim Schaefer, sales representative of a major global pharmaceutical company, walked into a medical center in New York to bring information and free samples of her company’s latest products. That day she was lucky – a doctor was available to see her. ‘Q1 The last rep offered me a trip to Florida. What do you have?’ the physician asked. He was only half joking.

B. What was on offer that day was a pair of tickets for a New York musical. But on any given day, what Schaefer can offer is typical for today’s drugs rep – Q2 a car trunk full of promotional gifts and gadgets, a budget that could buy lunches and dinners for a small country, hundreds of free drug samples, and the freedom to give a physician $200 to prescribe her new product to the next six patients who fit the drug’s profile. Q8 And she also has a few $ 1,000 honoraria to offer in exchange for doctors’ attendance at her company’s next educational lecture.

C. Q9 Selling pharmaceuticals is a daily exercise in ethical judgement. Salespeople like Schaefer walk the line between the common practice of buying a prospect’s time with a free meal and bribing doctors to prescribe their drugs. They work in an industry highly criticized for its sales and marketing practices, but find themselves in the middle of the age-old chicken-or-egg question – businesses won’t use strategies that don’t work, Q3 so are doctors to blame for the escalating extravagance of pharmaceutical marketing? Or is It the industry’s responsibility to decide the boundaries?

D. The explosion in the sheer number of salespeople in the field – and the amount of funding used to promote their causes – forces close examination of the pressures, Influences, and relationships between drug reps and doctors. Q10 Salespeople provide much-needed information and education to physicians. In many cases the glossy brochures, article reprints, and prescriptions they deliver are primary sources of drug education for healthcare givers. Q4 With the huge investment the industry has placed in face-to-face selling, salespeople have essentially become specialists In one drug or group of drugs – a tremendous advantage In getting the attention of busy doctors in need of quick information.

E. But the sales push rarely stops in the office. The flashy brochures and pamphlets left by the sales reps are often followed up with meals at expensive restaurants, meetings in warm and sunny places, and an inundation of promotional gadgets. Q11 Rarely do patients watch a doctor write with a pen that Isn’t emblazoned with a drug’s name or see a nurse use a tablet not bearing a pharmaceutical company’s logo. Millions of dollars are spent by pharmaceutical companies on promotional products like coffee mugs, shirts, umbrellas, and golf balls. Money well spent? It’s hard to tell. ‘Q5 I’ve been the recipient of golf balls from one company and I use them, but it doesn’t make me prescribe their medicine,’ says one doctor. ‘I tend to think I’m not influenced by what they give me.’

F. Free samples of new and expensive drugs might be the single most effective way of getting doctors and patients to become loyal to a product. Salespeople hand out hundreds of dollars’ worth of samples each week – $7.2 billion worth of them In one year. Though few comprehensive studies have been conducted, one by the University of Washington Investigated how drug sample availability affected what physicians prescribe. Q8 A total of 131 doctors self-reported their prescribing patterns – the conclusion was that the availability of samples led them to dispense and prescribe drugs that differed from their preferred drug choice.

G. The bottom line Is that pharmaceutical companies as a whole Invest more In marketing than they do in research and development. Q7 And patients are the ones who pay – in the form of sky-rocketing prescription prices – for every pen that’s handed out, every free theatre ticket, and every steak dinner eaten. Q12 In the end the fact remains that pharmaceutical companies have every right to make a profit and will continue to find new ways to increase sales. But as the medical world continues to grapple with what’s acceptable and what’s not, It is clear that companies must continue to be heavily scrutinized for their sales and marketing strategies.
