Sometimes I really doubt whether there is love between my parents. They are very busy working to  1  the family. They don’t act in the  2  ways that I read in books or I see on TV. 3  flowers to each other on Valentine’s Day is even more  4 .

One day, my mother was sewing a quilt(床罩). I  5  sat down beside her and looked at her. “Mom, is there love between you and Dad?” I asked her in a  6  voice.

My mother stopped and raised her head with  7 in her eyes. She didn’t answer immediately. Then she  8  her head and continued to sew the quilt. At last my mother said:

“Susan,” she said, “Look at this thread. Sometimes it appears, but most of it  9  in the quilt. The thread really makes the quilt strong and  10 . If life is a quilt, then love should be a  11 .It can hardly be seen anywhere or anytime, but it’s really there. Love is  12 .”

The next spring, my father suddenly got sick seriously. When they returned from the hospital, mother looked rather pale and it seemed  13 of them had had a serious illness. Every day in the morning and dusk, my mother helped my father  14  slowly on the country road. My father had never been so  15. Along the country road, there were many beautiful flowers, green grass and trees. The sun gently glistened through the leaves. All of these  16  the most beautiful picture in the world.

“Dad, how are you feeling now?” I asked him one day. He said gently. “ 17 , I just like walking with your mom. I like this kind of life.”  ___18  his eyes, I know he loves my mother deeply.

 19  I thought love meant flowers, gifts and sweet kisses. But from this  20 ,I understand that love is just a thread in the quilt of our life. Love is inside, making life strong and warm.

某12层高的公寓工程，在建筑物的四周搭设了一道高40M的封圈形扣件式钢管外脚手架，外装修以后，就将脚手架拆除。拆除时，将拆下来的构配件向地面抛掷，当拆到30M高时，往下掷一根钢管，刚好打在路过此处带着安全帽的施工员的头上，安全帽破碎，施工员当场死亡。请判断下列事故原因分析的对错。

拆脚手架没有按规定编制拆除方案，没有规定对拆下的构配件的运输方法

重症肌无力是由于机体产生能与乙酰胆碱受体特异性结合的抗体，但该抗体不能发挥乙酰胆碱的作用（如甲图所示）；“Graves氏病”是由于机体产生针对促甲状腺激素受体的抗体，而该种抗体能发挥与促甲状腺激素相同的生理作用，但甲状腺激素不会影响该抗体的分泌（如乙图所示）。请分析回答：

为了研究温度对激素分泌的影响，将一组小鼠依次置于25℃、0℃、25℃环境中，每一环境均生活15min，从开始到结束，每隔5min测一次皮肤血流量、血液中促甲状腺激素、甲状腺激素的含量，共测10次，假设测量过程不影响激素的分泌，测量结果（相对值）如下表：

据题中所给信息可知，进入0℃环境时，首先增加的生理指标是（）（用表中字母表示）。实验过程中，能直接调节小鼠产热量和散热量的生理指标分别是（）（用表中字母表示）。表中A的分泌受（）激素的调节。
