But what you have here is actually four separate layers, and I'm curious which of you can see the four separate layers and, particularly, how when they're compressed together and presented to the student all at once, how that creates this impatient problem solving.
但在这里有四个不同层面。 我很好奇你们哪个可以看到这四个不同层面的， 特别是，它们如何压缩在一起， 一次性的展现给学生， 又如何轻易地解决了问题。
