比如说实验部分:In the example of tying shooes. One group of college students were told that they were being obseved and the other donot know they were being observed.
如果说速度的时候再说the group of college students were told that they were being obseved tied their shooes faster than the other gourp 会不会太罗嗦,而且浪费时间?
在这里已经说过了每一组的情况,后面说速度的时候能不能直接说the first group's spped of tying is faster than the other?
