结合语境,简述文中加点的“音符”的具体意思。

  暮春,在江南水乡的庭院,竞邂逅映山红。它被安置在方丈之地,前有池后有石,左有梅竹右有庭廊,草丛、紫藤等占满了它周围的空间。它在这闹市之中小巧玲珑的人造景观中作着陪衬,作着点缀,作着阳春白雪中不显山不露水的一个音符。修剪整齐而丛密的绿叶间开着几朵暗红的喇叭花朵,中规中矩,小心翼翼,含蓄内敛,不事张扬。那几个含苞欲放的骨朵,正按部就班地耐心等待,等首批花凋谢后,它再绽放。

  我禁不住有几分悲哀,想起家乡大别山的映山红。映山红本不是这样的呀。那本是狂野奔放的花,映着云霞燃着激情红透春末夏初季节的花。

  春分一过,大别山的漫山遍野是映山红的天下。那殷红的花骨朵,点点滴滴,洒遍群山。宛如有一场红雨,又像点点音符,滴在五线谱上,奏响春之歌,灌木的嫩芽像雀舌,和煦的春风像软绸。

题型:完形填空
A good student is always equated to one who gets good grades. But is that all that a good student is? What is a   1 good student? Is he someone who is the teacher's pet? Someone who tops every test? Someone who has the smarts? A good student is all this and more, because, you see, it’s not just about books and repetitive  2 .
Being a good student takes much more than that. There are certain  3 that make him a good student. That is  4 what we shall be looking into – the qualities of a good student. There will help you  5 what a good student is and what are the qualities that one needs in order to become one.
A good student has great   6 skills. He has the ability to plan and organize not only his actions but his  7 as well, for being well organized allows a person to be prepared for all the situations that are to   8 . That could not have been   9 if he had taken up the studies at the last minute.
Knowledge is a key  10 that defines(定义) a student. Possessing knowledge that is not only limited to books but also   11 things about current affairs and other things allows him to draw from all that he possesses and use it in his studies.
There is nothing that comes without hard work and that is exactly what a good student has to possess. A   12 student is not someone who will turn away from work, or try to find   13 s to get the work done  14 or for the sake of finishing it. He is instead someone who will do his work sincerely and put in all his efforts without compromising on quality.
