So actually, the problem with static semantics is you'd like it to catch everything, you don't always get it.
因此实际上，你希望静态语义检查,能捕获所有的错误，但是经常结果不是这样的。
-
OK. What happens if you actually have something that's both syntactically correct, and appears to have correct static semantics, and you run it?
好，当你的代码语法,没错误，并且也有正确的静态语义，你去运行它的时候会发生什么呢？
-
Not everything is going to get caught in static semantics checking.
并不是所有的错误,都会在静态语义检查中被捕获。
-
The last piece of it is, in addition to having static semantics, we have sort of full semantics.
最后一部分是，除了static语义之外，我们还有一些full语义。
-
What's the point? Again, you can have things that are syntactically legal but not semantically meaningful, and static semantics is going to be a way of helping us decide what expressions, what pieces of code, actually have real meaning to it. All right?
重点是什么？重申，你可以有东西在语义结构的逻辑上有意义,但是在语义上无意义，而static语义,将是一个帮助我们,决定哪些表达，哪部分的代码实际上，有意义的途径，好么？
