About a year ago, a couple with three children moved into the apartment next door to me.

I never heard any noise from the children, but I often heard the parents shouting at the kids, not in a nice voice, but in a terrible one.

小题1:_______________. I always greeted them, but the only answer I ever got was a “hello” from the eight-year-old girl. 小题2:__________________. One day, when I returned from the hospital, the family were just leaving their apartment and the little girl was holding the outside gate open for the others. I remained in the car doing something unnecessary because I didn’t want to be snubbed(冷落、怠慢)again. When I finally got out of my car and walked towards the gate, the parents were telling the little girl to hurry and get in the car. 小题3:_________________. I hurried though I was still in pain from my leg.

Later that day I wrote a note saying how much her act of kindness had touched an old man’s heart.

The next day the family came over. 小题4:__________________. Her parents thanked me as well.

Now when we meet in the hall, we always greet each other, in a friendly way.

Last night there was a heavy snow. 小题5:_________________. I looked out of the window, thinking what I could do. To my great surprise, there was no snow on my car at all! I was even more surprised to see the lovely girl standing by the gate with an old broom.

Isn’t it amazing that the little kind act of an eight-year-old girl can change so many things for the better?

问题情境：将一副直角三角板（Rt△ABC和Rt△DEF）按图1所示的方式摆放，其中∠ACB=90°，CA=CB，∠FDE=90°，O是AB的中点，点D与点O重合，DF⊥AC于点M，DE⊥BC于点N，试判断线段OM与ON的数量关系，并说明理由．

探究展示：小宇同学展示出如下正确的解法：

解：OM=ON，证明如下：

连接CO，则CO是AB边上中线，

∵CA=CB，∴CO是∠ACB的角平分线．（依据1）

∵OM⊥AC，ON⊥BC，∴OM=ON．（依据2）

反思交流：

（1）上述证明过程中的“依据1”和“依据2”分别是指：

依据1：                                                        ；

依据2：                                                        ．

（2）你有与小宇不同的思考方法吗？请写出你的证明过程．

拓展延伸：

（3）将图1中的Rt△DEF沿着射线BA的方向平移至如图2所示的位置，使点D落在BA的延长线上，FD的延长线与CA的延长线垂直相交于点M，BC的延长线与DE垂直相交于点N，连接OM、ON，试判断线段OM、ON的数量关系与位置关系，并写出证明过程．
