昨晚衝澡時想了兩個句子你看看

第一句：開車時請不要危險換線。有四個/ein/的發音。

Refrain from changing lanes dangerously.

第二句：一個留在西班牙的油漆工，被安排培訓在令人痛苦的雨天裏維護下水道，這樣他能得到一些可卡因。

A painter remained in Spain was arranged to be trained to maintain the drainage in painful rainy days so he could gain some cocaine.

數一數這裏有多少個/ein/



另外，怎敢當老師，充其量是個師弟。
