母亲，是世界上最神圣的字眼，它包含了最伟大的爱。“慈母手中线，游子身上衣”可能也是我们最熟悉的诗句了。今天，就让我们借一首小诗，献上对母亲深深的爱吧！
You are not my birth mom - My real Mom wasn't you. 
But You are oh so special - and the loving things you do
Make me feel so valuable - You cheer me up when I'm sad.
And If you were my Real Mom I know I would be glad.
- Birth：表示“出世、诞生”等意思，比如，The birth of a child（小孩的出生）。在这里，birth表示“身世、出身”，You are not my birth mom就是“您（虽）不是我的亲生母亲”的意思。另外还有birth brothers and sisters就表示“同胞兄弟姐妹”的意思。
- Cheer up：表示“使……振作起来”的意思，它的同义词是buck up。如果你想安慰伤心的朋友，就可以说 Cheer up! The news is not so bad.（振作一点吧，也不是什么太坏的消 息）。这句话可是很顶用的呵！
Moms are special people. They are loved and needed so. 
Now I am thinking of You. And I wanted you to Know -
That since it's time for Mothers' Day -
And though you're just on loan -
I Love you just as much As If you were My very own!
- On loan：on loan的本意是“借来的”。哇！借来的妈妈！你听说过吗？开个小玩笑，在这里on loan其实表示“非亲生的”的意思。
