Hi learners! It's Sharon again, and I'm back this week to answer an email from a fellow educator. As someone who loves thinking about language learning through the eyes of the learner, I’m really excited to tackle this week’s question.

In each lesson, you're taught a handful of new words or structures by seeing them in sentences made up of only familiar words and grammar, plus the specific new thing. Here are two ways we introduce new words:

法国有句谚语：Petit à petit, l'oiseau fait son nid（一点一点，鸟儿筑巢）。这就是我们在Duolingo课程中采取的方法：我们给你提供一些比你已经掌握的语言略微高级一点的课程和练习。在每节课中，你会通过看到由熟悉的词汇和语法构成的句子以及特定的新内容来学习一些...
