学习难度
英语常用 to + 动词表示目的，也可用 in order to、so that、for + 名词/动名词来说明做某事的目的。
I came here to learn.
to learn 表示目的：I came here（我来这里）是为了 learn（学习）。
常见易错点
学习者可能把表示目的的 to do 和 for doing 混淆，或受中文“为了”影响而过度使用 for。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
