Текст: «Три версии одного абзаца: исследование, пресс-релиз, заметка»
In a randomised trial involving 1,240 adults aged 40–65 in two English towns, participants who walked for at least 30 minutes on five or more days a week over 12 months showed a mean reduction in systolic blood pressure of 4.1 mmHg relative to controls. The effect was observed in participants with elevated baseline pressure and was not statistically significant in those with normal baseline readings. Adherence was self-reported. The findings suggest that moderate regular walking may reduce blood pressure in middle-aged adults with elevated readings; they do not establish an effect in the general population, nor do they indicate the mechanism.
VERSION 2 — from the university press release
Walking for half an hour a day lowers blood pressure, a major new study has found. Researchers followed more than 1,200 adults for a year and found that those who walked regularly reduced their blood pressure by more than four points — a change comparable to some medications. The effect was strongest in people whose pressure was already high. «This shows that a simple daily habit can make a real difference,» the lead author said. The team is now investigating why walking has this effect.
VERSION 3 — from a newspaper's health page
A daily walk is as good as pills for high blood pressure, scientists say. In a year-long study of 1,200 people, everyone who walked for 30 minutes a day saw their blood pressure fall by four points — the same as a standard dose of common medication. Doctors should prescribe walking before drugs, the researchers suggest. The study is the first to prove that exercise, not medication, is the answer to Britain's blood-pressure problem.
Задание
Напишите редакторскую записку (editorial note, 280–320 слов) для газеты: сопоставьте три версии и покажите, где смысл сместился (drift) — объём (everyone / all vs participants with elevated readings; virtually / largely), сила глагола (suggest → shows → prove), условия и уточнения (five or more days a week; self-reported; 12 months; relative to controls), несуществующие утверждения (as good as pills; prescribe walking before drugs), область действия (only, not all). Затем дайте исправленную версию заметки (5–6 предложений), верную аннотации, с сохранением всех уточнений (faithful; restore; qualifier; that is to say; in the sense that; which is not to say; respectively).
Образец ответа
Editorial note: three versions, three claims
The abstract, the press release and our draft make three different claims, and the drift runs in one direction — towards a stronger, wider and less conditional statement than the study supports.
Scope. The abstract restricts the effect to participants with elevated baseline pressure and says it was not significant in those with normal readings. The press release keeps a trace of this («strongest in people whose pressure was already high») but opens with an unrestricted claim; our draft removes the restriction altogether («everyone who walked»). Not all participants benefited — a subset did — and «everyone» is false, not merely loose.
Strength. The abstract says the findings «suggest» walking «may reduce» pressure. The release turns this into «shows» and «lowers»; our draft into «prove». Those are three different verbs with three different meanings, and only the first is supported.
Conditions. Two qualifiers vanish between versions: five or more days a week (the release says «half an hour a day», the draft «30 minutes a day») and «relative to controls». A third is never mentioned by either later version: adherence was self-reported, which the abstract flags as a limitation.
Claims from nowhere. «As good as pills», «the same as a standard dose» and «doctors should prescribe walking before drugs» appear in no version of the research. The release says «comparable to some medications»; the draft converts a comparison of size into a claim of equivalence and adds a recommendation the authors did not make. Nor did they say the study was «the first to prove» anything — the abstract says the opposite about the general population and the mechanism.
Corrected copy. A year-long randomised trial of 1,240 middle-aged adults in two English towns suggests that walking for at least 30 minutes on five or more days a week may lower blood pressure — in people whose pressure is already raised, that is to say, not in the general population. Among those participants, systolic pressure fell by about four points relative to a control group, a change the researchers describe as comparable in size to some medications, which is not to say equivalent to them. Adherence was self-reported, and the authors say the findings do not establish an effect in people with normal readings, nor explain the mechanism. The team is now investigating why walking appears to help.
lightbulbТри версии одного результата: объём (everyone vs a subset; not all), сила глагола (suggest / may → shows → prove), потерянные qualifiers (five or more days, relative to controls, self-reported), утверждения ниоткуда (as good as pills). Исправленная заметка — faithful: that is to say, which is not to say.
