suffice
vi.足够，是sufficient的动词形式
作业：
1、对于高阶英语学习者来说，每天学一个词是不够的。
For high-level English learners, studing one word everyday does not suffice.
PS: “高阶”可以用advanced；参考翻译在表达“每天学一个词”用的是 a word per day，我写得比较直译。
2、#内容输出
Nowadays everyone is surrounded by huge amounts of information. Only knowing does ont suffice. We should try to output it.
