If you were walking 3 miles a day, playing 18 holes of golf three times a week, or lifting 10-pound dumbbells for three sets of 10 reps, reduce activity to half a mile every other day, or nine holes of golf once a week with short walks on other days, or use 5-pound dumbbells for one set of 10 reps.

如果你以前每天步行3英里，每周打三次18洞高尔夫，或者举10磅哑铃做三组、每组10次，那么现在就把运动量减少到隔天走半英里，或者每周打一次9洞高尔夫、其他日子短距离散步，或者用5磅哑铃做一组10次。

Another set of participants had to count backward from 1,000 by nines as they watched the clips, occupying their conscious working memory.

另一组参与者在观看视频片段时，必须从1000开始以9为单位倒数，以此占用他们有意识的工作记忆。

A couple of Christmases ago, my youngest stepdaughter, who was nine years old at the time, got a Superman T-shirt for Christmas.

No disciplines have seized on professionalism with as much enthusiasm as the humanities. You can, Mr. Menand points out, become a lawyer in three years and a medical doctor in four. But the regular time it takes to get a doctoral degree in the humanities is nine years. Not surprisingly, up to half of all doctoral students in English drop out before getting their degrees.

没有哪个学科像人文学科这样热衷于专业化。梅南先生指出，你可以用三年成为律师，用四年成为医生。但在人文学科获得博士学位的正常时间却是九年。毫不奇怪，多达一半的英语专业博士生在获得学位前就退学了。
