But because we're now programming a computer at a lower level and because as we said last week, you really have to be precise and then careful to instruct this machine, this fairly dumb machine that will only do what you tell it to do very specific instructions, do we have to use a more precise syntax than just a puzzle piece might have previously allowed.
但是我们是要在电脑的低平台上编程不是吗?,那我们就要像我上周提到过的那样,一定要小心,小心,再小心地,操纵这台又聋又哑的机器,它只会根据你敲进去的,特定指令来做事,所以我们必须使用非常精细的语法,而不是模模糊糊,让人费解的概念。

但是由于在画路易斯结构时,其实,在某些情况下是可以的,你可以画一条虚线来表示一又二分之一键,但是在多数情况下,我们就把两个结构都画出来,而我们说这是一个共振结构的表示的方法是,把它们放在括号里,并在中间放一个双箭头。
