【文章內(nèi)容簡(jiǎn)介】 s 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 water molecules into push173。pull chaos that prevents them from turning into ice. To copy this mechanism, he and his colleagues synthesised spiral173。shaped molecules that were mostly water173。repellent—but had iron atoms at their centres that made them hydrophilic, or water173。loving. The resulting pounds were surprisingly effective at stopping ice crystals from forming. Some were also harmless to the roundworm Caenorhabditis elegans, indicating they might be safe for other animals.“These pounds are really cool because they are not proteins—they are other types of molecules that nonetheless can do at least part of what natural antifreeze proteins do，” says Clara do Amaral, a biologist at Mount St. Joseph University, who was not involved in the research. Gibson39。s antifreeze pounds will still need to be tested in humans, however, and may be only part of a solution. “We don39。t have the whole picture yet，” do Amaral adds. “It39。s not just one magical pound that helps freeze173。tolerant organisms survive. It39。s a whole suite of adaptations.”(　　)32. What will happen if organs are kept for a long time in temperatures below zero?A. They will have ice crystal formation inside.B.

It39。s a flexible management of words and actions, by which we make other people have a better opinion of us and themselves. It seeks to build a positive relationship. __36__．However, in the rush of daily life being polite is social behaviour that we find rare nowadays. __37__. They don39。t even take the time to look around. This has led to the loss of simple social rules some might take for granted and that are particularly powerful.__38__， people bee less and less attentive to others39。 feelings, for human interaction(互動(dòng)) is almost lost. Take for instance the rudeness we tolerate when a person is looking at his phone when talking to us.Being polite is not just a simple social elegance. __39__. These days “Please” and “Thank You” are forgotten. And not many people are aware that these two simple words can easily open or close any door to us. Unfortunately, they often forget to say these words.Hope is not lost. There are many ways we can improve our behaviour to achieve skills in politeness. There are simple things we can do to be considered as a polite and well173。mannered person. __40__， they will respect you back. Just make a change in our behaviour to start. Use simple words like “Excuse me”， “Please”， and “Thank you” every day. Be kind to receive kindness. Care and politeness will get you far in all aspects of life.A. As technology progressesB. People have bee more self173。absorbedC. As long as you show your politeness for peopleD. Since for many people being polite remains a challengeE. Many languages have specific means to show politenessF. It aims to respect a person39。s need to be liked and understoodG.
