当a的绝对值小于c的绝对值时,上式=c-a+a+c=2c
当a的绝对值大于c的绝对值时,上式=c-a-a-c= -2a

答案是B,但是你应该是打错单词了,vary作为动词原型,变为现在分词形式是应该在其后面直接加ing,即varying,而不是varing.
这里是现在分词表示伴随状态,vary这一动作的施出者是He ,a teacher,应该是主动的,所以用现在分词形式.
后半句的to make them more interesting .表示的是一种结果、目的,作为状语.
所以,我们可以把句子的主干看作是He is a teacher ___his lessons ,
再 简单点：He is a teacher .怎样的老师呢,就用现在分词短语来修饰 a teacher.
所以答案是B.

是形容词啊,
The elderly, the young
形容词前面加个the是可也代表名词的,语法里面有这种用法

(-3abc)×(-a^2c)^3 ×(-1/3a^2b)
=-3abc×a^6c^3×1/3a^2b
=-a^9b^2c^4

今年的生日让我真正读懂了父母之爱,原来他们的爱是如此的伟大,这个深奥的字我终于懂了.
　　我的生日总是很平常的.由于妈妈不给我过生日,所以每次我的生日都是吃了妈妈煮的两粒鸡蛋就这样过了.曾经不懂事的我,还觉得这样太无聊跟妈妈吵,有时吵完还过分地把妈妈煮给自己吃的鸡蛋摔烂,然后就跑到同学家去玩.今年我的生日已经过了,回忆在那个夜晚吃不到妈妈煮的鸡蛋的我,独自站在宿舍的阳台上.望着夜空,想着自己亲爱的妈妈,回忆起了自己在自己生日所做错的事,尝试想着在我诞生的时候妈妈的痛苦.顿时泪如泉涌流,泪水模糊了我的视线.突然间好想吃妈妈煮的鸡蛋,于是,女儿吃着自己煮的鸡蛋,想想任性的自己总是动不动跟自己的妈妈吵架.瞬间,无数的对不起浮现在我的脑海中,可是却无法跟自己的妈妈说.
　　这时让我回忆起了另一件事,记得我5岁生日的那天半夜,寒风凛冽,暴雨狂下着,突然我发起了高烧,爸爸妈妈急忙的给我量体温“39度”妈妈看到这个数字时眼眶已布满了晶莹的泪水.就在那样的夜晚,他们穿着单薄的睡衣,背着我直冲医院,路上没有一辆出租车,妈妈撑着伞,爸爸背着我,狂跑在路上.可恶的雨总是打在了他们的身上,他们的表情是那么的焦急……想到这里,父母感动的画面呈现在我的眼前,此时此刻眼泪象断了线的珠子,吧嗒吧嗒地落下来.
　　一年一次的生日就这样过了,我觉得今年的生日过的很有意义,虽然没有爸妈的陪伴,没有妈妈煮的鸡蛋.但是它让我读懂得了父母之爱.
　　爱的形式有多样：有和蔼可亲的师爱,有伟岸宽宏的父爱,有纯洁真挚的友爱,有超越世俗的关爱……然而妈妈对我的爱却是不一样的.
　　一次,我和姐姐写作业,却想要出去玩,不料却被妈妈发现,她说：“你们的作业都做完了?”“完了.”“拿来让我看看.”我心想：“这下完了,姐姐的作业完成了,而我……但我也做好了随时牺牲的准备,我就等着吃一顿‘竹笋炒肉’吧.”结果可想而知,的确证实了我的神机妙算.晚上我摸着红肿的屁股,陷入了沉思：妈妈,这就是您伟大的母爱吗?
　　临近期中考试,我正紧张地复习功课,妈妈兴冲冲地跑过来告诉我：“看你表现得好,妈妈奖赏你上一个月的补习班.”唉,这算什么奖赏呢?
　　吃罢晚饭,我正迎接明天的期中考试,可妈妈也不说关心一下,还让我自己复习.我真搞不懂：别人的妈妈都那么顺着自己的儿子,可我的妈妈呢?唉,天注定呀!命该如此.
　　考试完后,回到家.只见餐桌上,摆满了我最爱吃的菜,而且还有一杯牛奶,两个鸡蛋.爸爸回到家,看到这么丰盛的菜肴,口水忽流三千尺,正准备投入战斗,老妈急忙拦住：“不许动,这是给我儿子做的,你想吃,没门!”老爸风趣地说：“太阳打西边出来了,今儿怎么对儿子这么好.”“那当然了,儿子考试很累,要补一补嘛.”老妈快人快语.“哦,是这样,恍然大迷瞪.”爸爸说.
　　此时,我虽无语,却泪流满面.谜底终于揭开了,原来妈妈在考试前给我报补习班,是为了让我在班里不落后.再考试前一天晚上让我自己复习,是为了让我学会自己约束自己.考试后,给我做佳肴,是为了让我明白：只有成功了,才可以得到奖励.
　　这种爱,是非凡的爱.
