8.may as well
In the right hands no instrument sounds more beautiful, but put it in the wrong hands and you may as well step on a cat’s tail and listen to the sounds that result.
may as well…为习语,意为“不妨”、“还是……为好”等。如:
We may as well stay here for another day.我们不妨在这里再待一天。
注:有时可用might代替may,语气更委婉。如:
I expect I might as well be going.我想我该走了。
Since it’s a fine day we might as well walk.既然天气很好,我们不妨走着去。
【注】might as well还可用于指过去的情况或用于比较两个令人不愉快的情况。如:
This holiday isn’t much fun; we might as well be back home.这个假日过得真没意思,我们还不如呆在家里。
与其比较-may well
may well主要用于加强推测的语气，表示具有较大的可能性。如：
It may well be true.那很可能是真的。
What you say may well be true.你说的很可能是事实。
【注】may well中的may也可换成might或could，但语气更不确定。如：
He might well lose his job.他多半会丢了那份工作。
He might [could] well find that the course is too difficult.他很可能觉得这门课太难。
感悟
作者讲到了重大发现。首先说明研究限定范围——可客观测量以及评定优劣（with objective measures of performance）。
所研究领域的特征
First, there are always objective ways. Second, these fields tend to be competitive enough. Third, these fields are generally well established. Fourth, these fields have a subset of performers who also serve as teachers and coaches and who, over time, have developed increasingly sophisticated sets of training techniques that make possible the field’s steadily increasing skill level.
人们一般认为决定一个人在一个领域做的好的重要因素是他的动力motivation,但是通过仔细的研究作者发现更重要的是练习时间。他研究了三组小提琴演奏家——good, better, best，以及芭蕾舞演员，发现这些领域决定水平高低的恰恰不是人们认为的动力，而是练习时间长短。甚至在对小提琴演奏者的调查中，发现他们在其他方面几乎相同，值得注意的是都不喜欢为达到更高水平而付出的努力练习。差异明显的是练习时间。
从小提琴演奏者中得出的结论是：First, to become an excellent violinist requires several thousand hours of practice. Second, even among these gifted musicians—all of whom had been admitted to the best music academy in Germany—the violinists who had spent significantly more hours practicing their craft were on average more accomplished than those who had spent less time practicing.
我对这一点的体会是：这几天每天去做实验，从一开始什么都不会，战战兢兢，到现在已经可以独立进行许多操作，并且还能在操作中自己提出优化。有一点不好的地方是，操作太多次的实验就已经没有了新鲜感，做的时候就感觉很机械——可能进入了comfort zone~
还终于讲到了刻意练习，具体下一天仔细写。
