计步器想必大家都知道，那么计步器计数是否准确呢？下面小编为大家整理了关于计步器的准确性和好处的听力背景材料，既可以了解科技最新动向，又可以积累托福听力背景材料何乐而不为呢？好了，话不多少，快一起来阅读吧！
Sometimes it’s hard to get moving. So setting a goal for the number of steps you walk each day can be a good motivator. But how to keep track of your total? A new study finds that many of the widely available wearable step counters actually keep a pretty accurate count. The research is in JAMA.
有时候我们很是不想活动，所以有一个具体目标的行步数可以很好的激励我们。但是怎么统计每天的行步数呢？一项新的研究表明：很流行那种可携带的计步器计数很准确。
For the study, 14 volunteers agreed to walk on treadmills while decked out with 10 popular wearable or smartphone counting technologies. The devices were compared with actual manual counts of either 500 or 1,500 steps. So how’d they do?
针对这项研究，14个志愿者同意在跑步机上跑步，同时，携带10台职能的手机计数。这种设置和实际的人工计数相比较500步和1500步。他们是怎么做的呢？
Smartphone apps were better step trackers than wearable tech—but the wearables were not terrible either. They typically slightly undercounted, compared to manual tallies, for example. Some of the discrepancy between the apps and wearables could be because volunteers’ phones were in a pocket close to their hips where it may be easier to pick up specific movements. But in everyday life smartphones would not always be in a pocket, of course.
智能手机中的应用软件要比可携带的计步器准确，但是可携带的计步器也没有那么差。例如，他们总是比人工计数少算了一些。在智能手机软件和和可携带的计步器的差别是因为：志愿者的手机放在屁股的口袋里，所以它能够更精确的感觉到运动。当然在我们的日常生活中，智能手机并不总是在我们的口袋里。
Of the 10 apps or devices studied, the Fitbit One was most accurate and had good consistency.
在10个应用程序的研究中，Fitbit是最精确的也是和人工计数最一致的。
Although none of the counts were that far off—for example, clocking just 1,200 steps instead of 1,500—the findings suggest that it’s probably a good idea to take the numbers as a loose estimate. And if you can’t walk somewhere, you can still feel motivated to park a few hundred steps away from your final destination.
虽然每一种科技都相差不远，例如，时钟仅仅用1200步代替1500步。这项研究表明，这可能是个好主意用时间做一个大概的估计。
好了，以上就是小编为大家整理的托福听力最新背景材料，希望能够帮助大家积累背景知识，前程百利祝大家都能取得理想的托福考试成绩。
