About Examination
I don't remember how many examinations I've taken since I began my schooling. To tell the truth, I don't like examinations at all. I dare say that, in fact, no student likes examinations.
We often hear people say “Examinations are teachers' magic weapon”, so most of us may think it is our teachers who give us students so many examinations. But I don't think so. Almost all of them have once been students before they became teachers. We don't like examinations, and neither do our teachers, which may be reasonably concluded. What's more, the more examinations we take, the more time will be taken from our teachers and the more trouble our teachers have to take.
It is the system in our country, I think, that gives us students so many examinations. If there were no entrance examinations
And all the students could go up to the higher grades without competition, there would not be so many examinations in primary and middle schools. So it is important and necessary to reform the test system.
Only in this way can examinations be greatly reduced, and then all the students will be happier.

幸福是什么？因为每个人的感受不同，所以感到的幸福也都是截然不同的。有人认为玩耍很幸福，有人觉得考试得了高分很幸福，有人认为吃喝玩乐非常幸福……但是，我认为当一个人有梦想的时候，不停地去努力，持之以恒，最后获得了成功，你就会深深地感受到了幸福。 我有一个梦想，那就是当一个萨克斯演奏能手，现在要追上甚至超过我的萨克斯老师的演奏水平；我还有一个目标，我要达到一个美国萨克斯王子的水平程度，我要成为中国的萨克斯王子。这是我的梦想，一个美丽的梦想！ 三年前，我认识了一个新朋友，它的身体金光闪闪，样子迷人，如果仔细看的话，它像一个大“s”，它的体重不轻，按键特别多，看起来非常复杂。当时，我认为学习吹奏它，肯定不容易。
二月份我开始学习了。我来到教室之后没看见有人，只听到上楼梯的脚步声。这时，一个身材高大、穿着西服的男士上来了，他有一头乌黑浓密的头发，淡淡的眉毛，大大的眼睛炯炯有神，还戴着一副眼镜，显得文质彬彬。他就是我的老师——田老师。 田老师带我进入一个带有钢琴和架子鼓的教室。老师先教我吹萨克斯这个嘴儿。他告诉我想要吹好萨克斯，就得把嘴儿吹会了。我练了练，可费劲了。然后练自己的手指，每天一百下，手指酸得快要我的命了。 时间过得真快，一晃三年过去了，在我练的这三年中，练我的肺活量，手指柔韧度，练习节拍能力……我已经学会了不少曲子，有《同一首歌》，《夏日里最后一朵玫瑰花》，《雪绒花》……有时因为节拍不对的问题，我被老师和爸爸批评过。
有一次，我在练习中因为节拍不对，被田老师狠狠地骂了一顿，我伤心万分，都想要放弃学它了。可是，我想起了三年前给它一个承诺，我拿着它，说：“萨克斯，我曾经放弃各种课外活动，但自从我认识你，我就不想放弃你了。”它虽然是一种乐器，但是，我把它当成一个非常要好的朋友，我忍着狠话继续练。 在今年学校新年联欢会时，我跟着学校乐团一起演奏《新年好》，虽然紧张，但我还是照样演，演奏结束后，人山人海的大礼堂暴发出雷鸣般的掌声，我高兴万分。 这学期我的照片和事迹登上了《北京晨报》。看到这个，我觉得这些年的千辛万苦没白费。我深深地感受到了幸福的快乐！...
