📖 Bài đọc passage 1
Report on a university drama project
Drama student Imogen Clare-Wood describes a collaborative theatre project she took part in.
This project was born from discussions I had with other drama students about the kind of theatre productions we'd like to create. Although we had previously been involved in various university productions where we took on specific roles, such as costume designer, producer, director and so on, we now wanted to take a collaborative approach that was new to all of us. We wanted a project in which every voice would carry equal weight and everyone would be able to contribute to every aspect of the show. We decided that the way to achieve this feeling of collaboration would be to concentrate on the process by which the work emerged during auditions and rehearsals. We chose a play that we felt allowed varied interpretations - Harold Pinter's The Lover, a modern one-act play with just two characters. We decided we would use six actors cast as three different couples, and each pair would have a turn to perform on one of the three nights that the play was to be staged.
The next step was to hold auditions in order to find six actors who felt the same way about the project as we did. We were anxious not to create an 'us and them' feeling to the auditions, since collective ownership of the project was crucial to our ideas. So we ran the first round of auditions as a series of workshops, which we kept very informal and relaxed. Then we recalled fifteen actors for the second round of auditions. At this stage we wanted the reactions and ideas to flow and be explored by the group in the form of a discussion. We were looking for actors who could encourage other people's ideas but who were also eager to input their own thoughts. Possibly the hardest part of the whole process was sitting down afterwards and deciding on the final six actors who would take part in the project.
Our initial rehearsals were dedicated to creating a strong group dynamic and to exploring some of the themes of the play without explicit reference to the script. One of the strongest tools we used for this was 'freewriting' - an exercise in which one person would read out a list of unconnected words and the rest of the group would clear their minds and simply write something in response to those words. We found it helped us to gain insight into the different ways our minds work. It also meant that we got to know each other very well, very quickly!
It was only during the next phase of rehearsals that we finally began to work with the script. We had not yet decided on the pairings for the six actors at this point, and we had the non-actors on the team reading in addition to the people who would be doing the final performances. The whole team finally decided on the pairings of the actors by a vote, and miraculously it was a unanimous decision. The casting of the roles worked well and felt more natural than it had in any other show l've worked on. I think the dynamic that we developed over the early rehearsals was crucial in giving us three such strong onstage relationships.
Other decisions were made in much the same way. The publicity was the responsibility of one member of the team, but she asked everyone what they thought would be effective. She then made several different versions, and from these we chose the design we liked the most. The stage set was left more to the individual pairs of actors, but since a large part of the later rehearsals was observing and feeding back on the individual performances being created by each pair, everyone was able to help with set design. We initially planned that each pair would use the same stage set. However, due to the different ways they interpreted the script, it became important for the set to be adapted for each couple.
In the final performances, it was surprising that despite the collaborative nature of the project, a range of very different interpretations emerged. This is, of course, partly due to the tragicomic nature of Pinter's text, which allowed the pairs of actors to exploit these two disparate elements, tragedy and comedy, to different degrees.
The question and answer session held after the show was perhaps the most rewarding part of the project. The questions that the audience asked were interesting and insightful, and certainly made everyone in the team think about what we'd been doing, what we'd wanted to achieve and whether we'd achieved it. We were asked, among other things, about how successful our collaborative ethic had been, how we'd ended up with three such different shows, how we'd overcome the initial 'production team versus cast' divide, and how we would continue in the future.

A. Staying up an hour or two past bedtime makes it far harder for kids to learn, say scientists who deprived youngsters of sleep and tested whether their teachers could tell the difference. They could. If parents want their children to thrive academically, “Getting them to sleep on time is as important as getting them to school on time," said psychologist Gahan Fallone, who conducted the research at Brown Medical School.
B
B. The study, unveiled Thursday at an American Medical Association (AMA) science writers meeting, was conducted on healthy children who had no evidence of sleep- or learning-related disorders. Difficulty paying attention was among the problems the sleepy youngsters faced - raising the question of whether sleep deprivation could prove even worse for people with attention deficit hyperactivity disorder, or ADHD. Fallone now is studying that question, and suspects that sleep problems “could hit children with ADHD as a double whammy”.
C
Sleep experts have long warned that Americans of all ages do not get enough shuteye. Sleep is important for health, bringing a range of benefits that, as Shakespeare put it, “knits up the ravelled sleave of care”. Not getting enough is linked to a host of problems, from car crashes as drivers doze off to crippled memory and inhibited creativity. Exactly how much sleep correlates with school performance is hard to prove. So, Brown researchers set out to test whether teachers could detect problems with attention and learning when children stayed up late - even if the teachers had no idea how much sleep their students actually got.
D
They recruited seventy-four 6- to 12-year-olds from Rhode Island and southern Massachusetts for the three-week study. For one week, the youngsters went to bed and woke up at their usual times. They already were fairly good sleepers, getting nine to 9.5 hours of sleep a night. Another week, they were assigned to spend no fewer than ten hours in bed a night. The other week, they were kept up later than usual: First -and second-graders were in bed no more than eight hours and the older children no more than 6.5 hours. In addition to parents’ reports, the youngsters wore motion detecting wrist monitors to ensure compliance.
E
Teachers were not told how much the children slept or which week they stayed up late, but rated the students on a variety of performance measures each week. The teachers reported significantly more academic problems during the week of sleep deprivation, the study, which will be published in the journal Sleep in December, concluded. Students who got eight hours of sleep or less a night were more forgetful, had the most trouble learning new lessons, and had the most problems paying attention, reported Fallone, now at the Forest Institute of Professional Psychology
F
Sleep has long been a concern of educators. Potter-Burns Elementary School Sends notes to parents reminding them to make sure students get enough sleep prior to the school’s yearly achievement testing. Another school considers it important enough to include in the school’s monthly newsletters. Definitely, there is an impact on students’ performance if they come to school tired. However, the findings may change physician practice, said Dr. Regina Benjamin, a family physician in Bayou La Batre, who reviewed the data at the Thursday’s AMA meeting.“I don't ask about sleep” when evaluating academically struggling students, she noted. “I’m going to start.”
G
So how much sleep do kids need? Recommended amounts range from about ten to eleven hours a night for young elementary students to 8.5 hours for teens. Falloneinsists that his own second-grader get ten hours a night, even when it meant dropping soccer - season that practice did not start until 7:30 — too late for her to fit in dinner and
time to wind down before she needed to be snoozing. “It’s tough,” he acknowledged, but “parents must believe in the importance of sleep."

A. Science plays an increasingly significant role in people’s lives, making the faithful communication of scientific developments more important than ever. Yet such communication is fraught with challenges that can easily distort discussions, leading to unnecessary confusion and misunderstandings.
B
Some problems stem from the esoteric nature of current research and the associated difficulty of finding sufficiently faithful terminology. Abstraction and complexity are not signs that a given scientific direction is wrong, as some commentators have suggested, but are instead a tribute to the success of human ingenuity in meeting the increasingly complex challenges that nature presents. They can, however, make communication more difficult. But many of the biggest challenges for science reporting arise because in areas of evolving research, scientists themselves often only partly understand the full implications of any particular advance or development. Since that dynamic applies to most of the scientific developments that directly affect people’s lives global warming, cancer research, diet studies – learning how to overcome it is critical to spurring a more informed scientific debate among the broader public.
C
Ambiguous word choices are the source of some misunderstandings. Scientists often employ colloquial terminology, which they then assign a specific meaning that is impossible to fathom without proper training. The term “relativity,” for example, is intrinsically misleading. Many interpret the theory to mean that everything is relative and there are no absolutes. Yet although the measurements any observer makes depend on his coordinates and reference frame, the physical phenomena he measures have an invariant description that transcends that observer’s particular coordinates. Einstein’s theory of relativity is really about finding an invariant description of physical phenomena. True, Einstein agreed with the idea that his theory would have been better named “Invarianten theorie.” But the term “relativity” was already entrenched at the time for him to change.
D
“The uncertainty principle” is another frequently abused term. It is sometimes interpreted as a limitation on observers and their ability to make measurements.
E
But it is not about intrinsic limitations on any one particular measurement; it is about the inability to precisely measure particular pairs of quantities simultaneously? The first interpretation is perhaps more engaging from a philosophical or political perspective. It’s just not what the science is about.
F
Even the word “theory” can be a problem. Unlike most people, who use the word to describe a passing conjecture that they often regard as suspect, physicists have very specific ideas in mind when they talk about theories. For physicists, theories entail a definite physical framework embodied in a set of fundamental assumptions about the world that lead to a specific set of equations and predictions – ones that are borne out by successful predictions. Theories aren’t necessarily shown to be correct or complete immediately. Even Einstein took the better part of a decade to develop the correct version of his theory of general relativity. But eventually both the ideas and the measurements settle down and theories are either proven correct, abandoned or absorbed into other, more encompassing theories.
G
“Global warming” is another example of problematic terminology. Climatologists predict more drastic fluctuations in temperature and rainfall – not necessarily that every place will be warmer. The name sometimes subverts the debate, since it lets people argue that their winter was worse, so how could there be global warming? Clearly “global climate change” would have been a better name. But not all problems stem solely from poor word choices. Some stem from the intrinsically complex nature of much of modern science. Science sometimes transcends this limitation: remarkably, chemists were able to detail the precise chemical processes involved in the destruction of the ozone layer, making the evidence that chlorofluorocarbon gases (Freon, for example) were destroying the ozone layer indisputable.
H
A better understanding of the mathematical significance of results and less insistence on a simple story would help to clarify many scientific discussions. For several months, Harvard was tortured by empty debates over the relative intrinsic scientific abilities of men and women. One of the more amusing aspects of the discussion was that those who believed in the differences and those who didn’t use the same evidence about gender-specific special ability? How could that be? The answer is that the data shows no substantial effects. Social factors might account for these tiny differences, which in any case have an unclear connection to scientific ability. Not much of a headline when phrased that way, is it? Each type of science has its own source of complexity and potential for miscommunication. Yet there are steps we can take to improve public understanding in all cases. The first would be to inculcate greater understanding and acceptance of indirect scientific evidence. The information from an unmanned space mission is no less legitimate than the information from one in which people are on board.
I
This doesn’t mean questioning an interpretation, but it also doesn’t mean equating indirect evidence with blind belief, as people sometimes suggest. Second, we might need different standards for evaluating science with urgent policy implications than research with the purely theoretical value. When scientists say they are not certain about their predictions, it doesn’t necessarily mean they’ve found nothing substantial. It would be better if scientists were more open about the mathematical significance of their results and if the public didn’t treat math as quite so scary; statistics and errors, which tell us the uncertainty in a measurement, give us the tools to evaluate new developments fairly.
J
But most important, people have to recognize that science can be complex. If we accept only simple stories, the description will necessarily be distorted. When advances are subtle or complicated, scientists should be willing to go the extra distance to give proper explanations and the public should be more patient about the truth. Even so, some difficulties are unavoidable. Most developments reflect work in progress, so the story is complex because no one yet knows the big picture.

G. “Global warming” is another example of problematic terminology. Climatologists predict more drastic fluctuations in temperature and rainfall – not necessarily that every place will be warmer. The name sometimes subverts the debate, since it lets people argue that their winter was worse, so how could there be global warming? Clearly “global climate change” would have been a better name. But not all problems stem solely from poor word choices. Some stem from the intrinsically complex nature of much of modern science. Science sometimes transcends this limitation: remarkably, chemists were able to detail the precise chemical processes involved in the destruction of the ozone layer, making the evidence that chlorofluorocarbon gases (Freon, for example) were destroying the ozone layer indisputable.
H. A better understanding of the mathematical significance of results and less insistence on a simple story would help to clarify many scientific discussions. For several months, Harvard was tortured by empty debates over the relative intrinsic scientific abilities of men and women. One of the more amusing aspects of the discussion was that those who believed in the differences and those who didn’t use the same evidence about gender-specific special ability? How could that be? The answer is that the data shows no substantial effects. Social factors might account for these tiny differences, which in any case have an unclear connection to scientific ability. Not much of a headline when phrased that way, is it? Each type of science has its own source of complexity and potential for miscommunication. Yet there are steps we can take to improve public understanding in all cases. The first would be to inculcate greater understanding and acceptance of indirect scientific evidence. The information from an unmanned space mission is no less legitimate than the information from one in which people are on board.
I. This doesn’t mean questioning an interpretation, but it also doesn’t mean equating indirect evidence with blind belief, as people sometimes suggest. Second, we might need different standards for evaluating science with urgent policy implications than research with the purely theoretical value. When scientists say they are not certain about their predictions, it doesn’t necessarily mean they’ve found nothing substantial. It would be better if scientists were more open about the mathematical significance of their results and if the public didn’t treat math as quite so scary; statistics and errors, which tell us the uncertainty in a measurement, give us the tools to evaluate new developments fairly.
J. But most important, people have to recognize that science can be complex. If we accept only simple stories, the description will necessarily be distorted. When advances are subtle or complicated, scientists should be willing to go the extra distance to give proper explanations and the public should be more patient about the truth. Even so, some difficulties are unavoidable. Most developments reflect work in progress, so the story is complex because no one yet knows the big picture.
