1-- My doctor says that I need a blood test.
 
2-- I can help you with that. Just have a seat and roll up your left sleeve.
 
1-- What are you taking my blood for?
 
2-- Your doctor has requested a check of your white blood count.
 
1-- What information does that give him?
 
2-- If your white blood cell count is off, it could signal an infection somewhere in your body.
 
1-- Is a blood test painful?
 
2-- I am putting a tourniquet on your arm to plump up the vein. It will only feel like a little pin prick.
 
1-- Oh, my God, that hurts!
 
2-- That was it! Thank you for coming in today.

1--我的医生说我需要验血。
2--我可以帮你。坐好，卷起你的左袖。
1--你拿我的血干什么？
2--你的医生要求检查你的白细胞计数。
1--这给了他什么信息？
2--如果你的白细胞计数下降，这可能是你身体某个地方感染的信号。
1--验血疼痛吗？
2--我在你手臂上绑止血带，以使静脉丰满。这只会让人觉得有点刺痛。

2--就是这样！谢谢你今天来。
