小标题就像题目一样,只不过大题是一篇作文的总结,小标题是一段内容的总结罢了.

口语化就不能太啰嗦了!
I remember once I invited a friend to have dinner at seven in the evening.I went to a restaurant earlier and ordered the foods in advance to show my sincerity.But he didn’t turn up at seven and instead he gave me a call saying he couldn’t make it because he’s tied up; so the foods were wasted just like that.Ever since then,I’d never order foods in advance when inviting friends for meals.

Who do you usually have supper with?

早晨七点到晚上七点的12个小时内,挂钟上时针与分针所成的角为平角的次数有（11）次,理由如
下：∵当两次成平角之间的时间间隔为1小时60/11分钟=720/11分钟（计算方法类似于重合）,
∴成平角次数=720÷720/11=11次

His vocal concert will begin at 7 in the evening and last three hours.

每一小时成一条线1次
可是在12点整时重合的那次被在11点12点算了两次
所以一共12-1=11次

一个无私奉献的人
人并非为获取而给予；给予本身即是无与伦比的欢乐；对人来说,最大的欢乐,最大的幸福是把自己的精神力量奉献给他人.
——题记
奉献,是人的一种多么高尚的精神,是一种多么高尚的情操
在一个冰冷冰冷的冬天,寒风刺骨,连人也不敢出门,我真怪老天爷,今天这么冷还让我上学.我匆匆地吃了早餐,背着书包出门去了.在路上,阵阵刺骨的寒风迎面而来,我只好硬着头向前走.在不远,一根大竹把我拦住了,我陡然停止,闷闷不乐地顾视前方.只见离大竹不远有一位清洁工正毫无怨言地为人们挖通前几天被堵塞的‘臭水渠’.他挨着冷,忍受着恶心的臭味,用一双差不多被冻僵的手紧紧地拿着铁铲,然后用力地把铁铲插进了被堵塞的‘臭水渠’里,再把铲起的垃圾倒到旁边的桶里``````突然,大事不妙,‘臭水渠’里面被塞实了,用铁铲铲不行,用夹子夹不行,那位清洁工只好戴着手套下去挖.她下倒了‘臭水渠’,冰冷的水像一支支利箭直刺她的脚.她忍受着疼痛,仍吃苦受累地挖``````行人看见了也热心地走过来对清洁工说：“刘阿姨,别再挖了.天这么冷,你叫几个负责这工作的人来替你挖就行了,何况这工作又不是你负责的,你就快回去休息吧!”“咦!这是怎么回事?这工作不是她负责的?那她这么辛苦来做这干啥呢?``````”想着想着,我不由自主地被她那种无私奉献的精神深深地打动了,便情不自禁地走到她身旁,轻声细语地对她说：“阿姨,别再挖了!你就叫几个负责这工作的清洁工来挖吧!快回去休息吧!”只见她抬起头,气喘吁吁地对我说：“我决不会回去休息的,我一定要把这条‘臭水渠’挖通.”看着她那倔强的样子,我只好无可奈何地上学去了.
过了几天,我们住的一带地方终于能通水了,大家也高兴得不得了.不知何时,那位清洁工在刺骨的寒风中辛勤工作的背影模模糊糊地浮现在我的眼前.
她的言行深深的教育着我,影响着我——一个无私奉献的人.
