答案

参考答案:早期妊娠的辅助诊断方法如下:(1)妊娠试验:妊娠后胎盘绒毛产生绒毛膜促性腺激素(HCG),利用HCG的生物学和免疫学特点,测定受检者体内有无HCG,以协助诊断早期妊娠的方法称为妊娠试验。(2)超声检查:应用B型断层显像法,在妊娠7周时可见到妊娠环及胎心搏动。超声多普勒法,最早在妊娠7周时听到胎心音。(3)黄体酮试验:黄体酮20 mg,肌内注射,每天1次,连续3~5天,停药后超过7天仍未出现 * * 流血,则早期妊娠可能性大。(4)基础体温测定:高温相持续3周以上不见下降,则早孕可能性大。

We were dressed  26 , and I was feeling a little 27   as I was carrying our shopping, so I decided to throw something away. I was walking towards a dustbin(垃圾箱) 28   I noticed a poor man walking out of the restaurant in front of us. He headed over to the nearby dustbin and started looking through it. I suddenly felt very  29   because I was about to throw away a new drink just because it was too heavy. I walked up to him and handed the 30   and some bread over to him.

But then he said, “Wow, this is my son’s lucky day!” With that, he thanked me happily and started off on his bike. I  34   heard him singing as he rode away. I got a warm 35   inside. I now understand what it  36   by the saying “Giving is getting”.
 37  it was only a little action, I got and learned more in those two minutes than I did in the rest of the month. Everyone in the world  38 help. Everyone can give help and everyone will be helped by showing kindness.
The scene of that man’s happiness caused by my small gift appears in my mind  39 I have the chance to do something nice. This is the power(力量)of   40 .
