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 21 have done a lot for us, directly or indirectly and most of us 22 everything to their kindness and love． When we 23 them respect, whether it is by bowing to them, or 24 them with a smile, or offering them any help they need, it is one way of 25 our own love and gratitude to them． 26, elders have also been through all the years you are 27 and know a little more about the world than you do． It is 28 that you do not agree with the belief of your elders, but this is nothing new．All younger generations have always 29 with their elders and it is these differences that bring changes in human 30 ．However much you disagree with them, give them credit for their 31． With changing times and 32 influences, youngsters no longer know what is interpreted as disrespect to elders．Youngsters should 33 express their views and if there are arguments, they should not 34 their voices． If there is no space on sofas or chairs, children will immediately 35 their places, and sit on the carpet．In buses and trains, youngsters are 36 to give up their places to older people．This is not a 37 of who has more rights．It is simply that those who are younger have the strength to bear 38_, or tolerate unpleasantness, so it is natural to show consideration to those who are older and perhaps at a 39 disadvantage． When you do simple things as a mark of respect, elders become 40 that youngsters care for them, and they respond with affection and kindness．
