Directions:This part is to test your reading ability.There are five tasks for you to fulfill.Youshould read the reading materials carefully and do the tasks as you are instructed.TASK 1Directions:After reading the following passage,you will find five questions or unfinshedstatements numbered from 36 to 40.For each question or statement there are four choicesmarkted A,B,C and D.You should make the correct choice and mark the corresponding letter onthe Answer Sheet with a single line through the center. Do you remember a time when people were a little nicer and gentler with each other I certainly do and I feel that much of the world has somehow gotten away from that.Too often Isee people rushing into elevators without giving those inside a chance to get off first,or never saying"thank you",when others hold the door open for hem.We get lazy,and in outr laziness we think that something like simple"thank you"does not really matter.But it can matter very much.The fact is that no matter how nicely we dress or how beautifully we decorate our homes,we cannot be truly elegant unless we have good manners,because elegance and good manners alwaysgo hand in hand.If fact,I think of good manners as a sort of hidden beauty secret.Haven’t you noticed that happens,but it does.Take the long-lost art saying"thank you",like wearing a little make-up or making sure you hair is neat.Getting into the habit of saying"thank you"can makeyou feel better about yourself.Good manners add to your image while an angry face makes the best-dressed person look ugly. According to the speaker,how can we improve our image

A. By decorating our homes.
By being kind and generous.
C. By wearing fashionable clothes.
D. By putting on a little make-up.
