Conversation begins almost the moment we come into contact with another and continues throughout the day (56) the aid of cell phones and computers. However, we are so often absorbed in conversation that we (57) sight of its true purpose and value.One important (58) of a good conversation is that the words are (59) used to express thoughts and feelings. We are (60) deep thoughts and strong emotions, yet our vocabularies are not (61) for this expression, and many (62) little effort to expand that. Perhaps you see a movie that (63) you deeply, yet you have the following conversation: “So, what did you think of the film” “Oh, my God, it was so sad, I swear. I went through (64) a box of tissues (面巾纸). I was in tears.” This dialogue is (65) an effective way of expressing feelings. It gives no (66) of how or why the movie truly (67) you. Such commonly-used phrases are certainly not enough to describe a deeply moving experience. However, not only (68) try to avoid overused words, you must (69) be careful in your selection. The purpose of expanding vocabulary is not to use the (70) or most impressive words, but to find those best suited. What is lacking in many conversations is the ability to talk to another rather than just talking with that person. A (71) person will find that even in the most ordinary conversations. There are a thousand questions (72) to be asked if you have courage and a desire for exchange. Good conversations should not be (73) nonsense, but of a meeting of two (74) the human condition. It should bring a better understanding of others and offer a release of emotions more than drive away (75) thoughts or kill time.
在窗体上画一个文本框(名称为Text1)和一个标签(名称为Labe11)，程序运行后，在文本框中每输入一个字符，都会立即在标签中显示文本框中字符的个数。下列可以实现上述操作的事件过程是( )。
阅读下面短文，回答下面问题。 树是一部活档案，树干的年轮就是历史的记录。1901年，美国人道格拉斯发现居住地附近新近砍伐留下的树桩上，都有相同的图案纹理，譬如说，这些树木年轮的外面三圈都较宽，这表明近3年居住地附近环境与气候条件较好，树木生长较快。担相反的结论也可以由此得出。这个发现促使道格拉斯致力于树木年乾的深入研究。他用“同一地区，同时期年轮模式相同”的假设，以“接龙”的方式，来推算老树的初生年份。比如，有一棵被砍伐的百年古树，其砍伐年代不详，但是它的年轮中有一圈与当地一棵1864年砍下的大树的年轮最外圈相吻合。由于最外圈是被砍伐当年的年轮，因此这相吻合的一圈为1864年的年轮。由此向内按每进一圈是一年的方法推算，就可以算出这棵树大约哪一年栽种的。 一些科学家还根据年轮推算出发生过酸雨的年份。哥伦比亚大学的雅格比解释说，随着树木越长越老，年轮也变得越来越窄，而酸雨对树木恰恰起着相反的作用。年轮还可以记录下火山爆发与地震。火山爆发时，大量灰尘与气体进入同温层，遮住了阳光，这会使温度降到冰点以下，给树木留下一道叫做“霜轮”的特殊标记。东印度群岛坦波拉山爆发曾使1816年成了“没有夏天的一年”，这个标记甚至出现在南非的树木上。地震也可以给树木造成损害，使树在以后的一些年中形成较窄的年轮。由此看来，倘若说树木年轮“泄漏天机”，似乎并不为过。 (佚名《年轮》) 道格拉斯提出假设的主要事实依据是：
