题目内容

【题目】矿井坍塌导致工人被长时间困在井下,缺少水源和食物。下列叙述正确的是

A.机体抗利尿激素分泌增多能减少水分丧失

B.为维持内环境的稳定,机体分泌的胰岛素增多

C.机体缺水引发下丘脑调节中枢产生渴觉

D.机体内储存的糖原减少,细胞外液渗透压降低

【答案】A

【解析】抗利尿激素能促进肾小管和集合管对水的重吸收,使尿量减少,所以机体抗利尿激素分泌增多能减少水分随尿液丧失,A项正确;工人长时间缺少食物,会导致血糖浓度降低,为维持内环境的稳定,机体分泌的胰高血糖素增多,B项错误;渴觉是在大脑皮层的渴觉中枢产生的,C项错误;由B项分析可知,体内胰高血糖素分泌增多,会促进肝糖原分解和其他非糖物质转变成葡萄糖进入血液,使血糖浓度维持相对稳定,同时由于缺少水源会使细胞外液渗透压升高,故D项错误。

【题目】D

Most people I meet want to develop more harmonious and satisfying relationships. But we may not realize that this can only be achieved by partnering with two new and strange allies(盟友): uncertainty and confusion. Most of us arent trained to like confusion or to admit we feel hesitant and uncertain. In our schools and organizations, we place value on sounding certain and confident.

As life continues to speed up, I believe our changing world requires less certainty and far more curiosity. Im not suggesting we let go of our beliefs, but that we become curious about what someone else believes. As we become open to the disturbing differences, sometimes we discover that anothers way of interpreting the world is actually essential to our survival.

For me, the first step in becoming curious is to admit that Im not succeeding in figuring things out by myself. If my solutions dont work as well as Id like, I take these as signs that its time to begin asking others what they think. I try to become a conscious listener, actively listening for differences.

There are many ways to listen for differences. Lately, Ive been listening for what surprises me. This isnt easy Im accustomed to sitting there, nodding my head as someone voices his opinions. But when I notice what surprises me, Im able to see my own views more clearly, including my assumptions.

If youre willing to be disturbed and confused, I recommend you begin a conversation with someone who thinks differently from you. Listen for whats different and what surprises you. Try to stop the voice of judgment or opinion and just listen. At the end, notice whether youve learned something new.

We have the opportunity many times a day to be the one who listens to others and the one who is curious rather than certain. When we listen with fewer judgments, we always develop better relationships with each other. Its not differences that divide us. Its our judgments that do. Curiosity and good listening bring us back together.

As I consider partnering with confusion and uncertainty, Im learning that we dont have to agree with each other in order to think well together. There is no need for us to be joined at the head. We are already joined by our hearts.

【题目】B

I used to believe courtesy was a thing of the past. Very seldom have I encountered a courteous human being in this modern era.

Recently, I had to change my thinking when I came face to face with just such a human being in a coffee place, with my two daughters. The place was crowded as usual and we had to climb steep(陡峭的) stairs in order to find an empty table. After enjoying coffee and snacks, we went down the narrow stairs, where there was hardly any space for another person to either climb up or come down.

Just as I was in the middle of the stairs, a gentleman entered the main entrance of the restaurant which was right in front of the staircase(楼梯). I was sure I would be pushed roughly by this man going up. I kept coming down as fast as I could. My daughters were already down, looking up at me worriedly, hoping I would reach them before the stranger started walking up the stairs, knowing I was a nervous sort.

Nearly reaching them, I noticed the man still standing near the door. I reached my daughters and passed the stranger at the entrance door which he kept holding open. I looked back thinking he was still at the door, deciding whether to go in or find another less crowded place. I saw him going up the stairs, two at a time. I told my daughters about it and all three of us felt bad that we did not even thank the courteous gentleman who was actually holding the door open for us ladies to pass through before going up.

Such well-mannered people are hard to find these days, when pushing is very common in our advanced but aggressive society. We applauded for his chivalry(骑士精神).
