Hi Alex, I don't fully understand what you mean in sentence 1 and 2. The third one should be ''她病得很严重'' (严重 = grave) Other similar examples : 她病得很严重 = She is critically ill. (病 = ill) 她玩得很开心 = She plays happily. (玩 = play) 她哭得很难过 = She cries sadly. (哭 = cry)

1_My friend is upon of tree, can say him? 远的地方你有什么？ 他的远方有什么？ 2_Is this sentence correct grammatically? 大人要注意孩子们被小偷不偷走 大人要当心孩子们不被小偷偷走 3_Is this sentence correct grammatically? 她生病生的糟糕 她病的很严重。

大人们要小心，以防孩子被小偷偷走。 她病得很严重。
