(10 points) My husband kissed me goodbye, stroke (轻抚) the babys cheek and then rushed out of the door, into his busy day. With the
2、 cold of the morning fading, I fed my baby and it fell fast asleep. Usually I would place it in bed and quickly have the house somewhat in 1 .However, this morning, I stayed seated, just 2 , with the baby in my arms.

I had just realized the 9 of the ordinary the daily life going on around us that we often took for granted, and that it needed to be 10 .“Hi, Dad.” I said, 11 back tears.“Hey, Bud. How are you?” 12 was in his voice.“Fine,
5、Im just calling to saythank you.” I got it out before my throat 13 too much for me to speak.“What for?”“For getting up and going to work every morning of my life. Now that I have my own 14 and I see my husband doing the same, I just wanted to thank you for being 15 .”There was 16 for a moment as my
6、dad composed himself, and with a small 17 in his voice he said, “Youre welcome, Bud.”I dont remember much of the rest of the call, 18 that moment of revelation (显露) about my father, I will never forget. There are those who are known for their heroic 19 , and also those who are known for their fortun

Microscopic ice crystals (结晶体) cut cells and seize moisture (潮气), making donor organs unsuitable for transplantation. Thus, organs can
11、be made cold for only a few hours ahead of a procedure. But a set of lasting new antifreeze compounds (化合物)similar to those found in particularly hardy (耐寒的) animalscould lengthen organs shelf life.Scientists at the University of Warwick in England were inspired by proteins in some species of Arctic
12、 fish, wood frogs and other organisms that prevent blood from freezing, allowing them to flourish in extreme cold. Previous research had shown these natural antifreeze molecules (分子) could preserve rat hearts at -1.3 degrees Celsius for up to 24 hours. But these proteins are expensive to extract (提取
13、) and highly poisonous to some species. “For a long time everyone assumed you had to make synthetic (人造的) alternatives that looked exactly like antifreeze proteins to solve this problem, ”says Matthew Gibson, a chemist at Warwick who co-authored the new research. “But we found that you can design ne
14、w molecules that function like antifreeze proteins but do not necessarily look like them. ”Most natural antifreeze molecules have a mixture of regions that either attract or repel water. Scientists do not know exactly how this process prevents ice crystal formation, but Gibson thinks it might throw
15、water molecules into push-pull chaos that prevents them from tuning into ice. To copy this mechanism, he and his colleagues synthesized spiral-shaped molecules that were mostly water-repellentbut had iron atoms at their centers that made them hydrophilic, or water-loving. The resulting compounds were surprisingly effective at stopping ice crystals from forming. Some were also harmless to the roundworm Caenorhabditis elegans, indicating they
