题型:单项选择题
We should show respect to everybody, especially our elders because they are ahead of us — in age, in wisdom and maturity, in experience and education. Our   36  have done a lot for us, directly or indirectly and most of us   37  everything to their kindness and love.
When we   38  them respect, whether it is by bowing to them, or   39   them with a smile, or offering them any help they need, it is one way of   40  our own love and gratitude to them.   41 , elders have also been through all the years you are   42  and know a little more about the world than you do.
It is   43  that you do not agree with the belief of your elders, but this is nothing new. All younger generations have always   44  with their elders and it is these differences that bring changes in human   45 . However much you disagree with them, give them credit for their   46 .
With changing times and   47  influences, youngsters no longer know what is interpreted as disrespect to elders. Youngsters should   48  express their views and if there are arguments, they should not   49  their voices.
If there is no space on sofas or chairs, children will immediately   50  their places, and sit on the carpet. In buses and trains, youngsters are   51  to give up their places to older people. This is not a   52  of who has more rights. It is simply that those who are younger have the strength to bear   53 , or tolerate unpleasantness, so it is natural to show consideration to those who are older and perhaps at a   54  disadvantage.
When you do simple things as a mark of respect, elders become   55  that youngsters care for them, and they respond with affection and kindness.
