## 和 and 都

In Chinese, 和 as a conjunction is normally used to connect two words or
phrases, /never/ two clauses or sentences:

    中國和美國
    我的爸爸和媽媽
    她學習漢語和英語。
    你認識我爸爸和弟弟嗎﹖

    but not 我弟弟是學生﹐和我哥哥也是學生。
    nor 你學習法語﹐和我也學習法語。

The adverb 都 is placed between the subject and the predicative verb or
adjective. It governs only the elements /before/ it:

    我們都去中國。 (All of us go to China: 都 modifies 我們.)
    but not 都我們去中國。

This is also wrong:

    我都學漢語和法語。

because 都 modifies 我 and not 漢語和法語. If "both Chinese and French"
is intended in the above sentence, the objects 漢語和法語 should be
placed before 都:

    我漢語和法語都學。
    or 漢語和法語都我學。
