－a一定是（ ）
-a是a的相反数所以可以是正数，也可以是负数，还可以是0所以选D
a promise is a promise是哪部电影的经典台词
a+|-a|>=a-a=0选B
|a|=a,那么a一定是()
非负数
三分之a一定是分数，这句话对吗
不一定，如果a是3的整倍数，就是整了。
如当a=3 =6 =9......那a／3就是1 2 3.....所以说，这句话不对．
跪求越狱里面的一点台词
I'm sure you can understand my reluctance to discuss past patients. ( 你肯定理解 我不能谈论以前的病人 ) Absolutely. ( 当然 ) Uh,my understanding is that under hipaa, ( 呃,不过我也知道根据HIPAA法案 (健康保险便携与核算法案) ) we're allowed to share information as long as it furthers the care of the patient. ( 只要病人被转移治疗我们可以共享资料 ) I'm not accustomed to making inquiries like this,but,I,uh... ( 我不太习惯这样质问别人,但是,我... ) I feel like I can get through to him. ( 我感觉我可以治好他 ) I can help him. ( 我可以帮他 ) I imagine he needs it in there. ( 可以想像 他在那确实需要帮助 ) What did you treat him for? ( 你给他治疗什么病? ) Well,michael suffered from a couple of things. ( Michael有好几种病 ) One was a condition called low-latent inhibition. ( 其中一种叫做潜在抑制症 ) I'm sorry.I'm not familiar with the term. ( 不好意思,我不太懂术语 ) well,people who suffer from low-latent inhibition see everyday things just like you or I do. ( 这种病人看到的东西跟我们不一样 ) Like this lamp,for instance. ( 比如灯,做个例子 ) But where we just process the image of a lamp, ( 但我们眼中只能看到灯的形象 ) they process everything. ( 他们能看到一切 ) The stem,the bulb,the bolts,even the washers inside. ( 支架,灯泡,螺钉,甚至里面的垫圈 ) Their brains are more open to incoming stimuli in the surrounding environment. ( 他们的脑子对周围事物的信息更开放 ) Other people's brains-- ( 其他人的脑子-- ) yours and mine-- shut out the same information. ( 像你和我-- 则把这些信息关在外面 ) We have to do it in order to keep our sanity. ( 我们这么做是为了保持心智健全 ) If someone with a low iq has low-latent inhibition, ( 如果智商低的人患了潜在抑制症 ) it almost always results in mental illness. ( 结果通常是精神分裂 ) But if someone has a high iq, ( 但如果患者有足够高的智商 ) it almost always results in creative genius. ( 结果通常是极具创造性的天才 ) Do you think michael's a genius? ( 你认为Michael是天才吗? ) Well,I think that word's been derogated in the media these days, ( 这个词已经被当今媒体毁了 ) but in the classic sense of the word,yes,I do. ( 不过以这个词的本意来讲没错,是的 ) You-you said there was something else you treated him for. ( 你说他还有其它疾病 ) He came to me with absolutely no sense of self-worth. ( 他刚来的时候非常没有自信心 ) The loss of both parents very often does that to a child. ( 失去双亲的孩子通常都会这样 ) But with the low-latent inhibition, ( 但由于潜在抑制症 ) something interesting happened to michael. ( Michael身上发生了一些有趣的事 ) He became very attuned to all the suffering around him. ( 他变得对周围的苦难有强烈的共鸣 ) He couldn't shut it out. ( 他无法坐视不管 ) He became a rescuer, ( 他成了帮助者 ) one of those people who are more concerned with other people's welfare than their own. ( 这种人关心其他人的幸福远多过关心自己 ) I didn't know all this about him. ( 这些我一点都不了解 ) Then maybe you don't know michael scofield. ( 那说明你不了解Michael Scofield ) Yeah. ( 没错 ) 是这个吗
若|a|=-a,则a一定是什么
错误当a=0或a＜0时，不成立
