when 与 while 的区别
as,when,while的区别as,when,while的区别as,when,while都表示主、从句的动作或状态同时发生，但三者意义不尽相同。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如：MotherwasworriedbecauselittleAlicewasill,especiallyas/when/whilefatherwasawayinFrance.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如：Helookedbehindfromtotimeashewent.他一边走，一边不时地往后看。Astimegoeson,it’sgettingwarmerandwarmer..随着时间的推移，天气变得越来越暖了。Ithoughtofitjustasyouopenedyourmouth.你一张嘴我就知道你要说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.）当主从句之间表示转折或对比关系时，多用while,不用as或when。如：ShethoughtIwastalkingaboutherdaughter,whileinfact,Iwastalkingaboutmydaughter.她以为我在谈论她女儿，而事实上，我在谈论我的女儿。如果表示从句的动作在主句的动作“之前”或“之后”发生时，多用when（=after）,不用as或while。此外，when还含有“atthatmoment”的意思（=andthen），引起的句子不能放在句首，也不能用as,while来替换。例如：Hewasabouttoleavewhenthetelephonerang.他正要离开，忽然电话铃响了。WewerewatchingTVwhensuddenlythelightswentout.我们正在看电视，突然灯灭了。Theyhadjustarrivedhomewhenitbegantorain.他们刚到家，天就开始下雨了。
while和neither的用法
（1）while的用法： 连词while除具有“当时”、“同时”等意义外，根据上下文还有以下不同含义及其不同译法。 一、引导时间状语从句 译作“当……时”。例如： 1. Make hay while the sun shines. 趁着有太阳晒晒草。 (乘机行事，抓紧时机。) 2. We must work hard to gain more knowledge while we are young. 趁着现在还年轻，我们必须刻苦学习，获得更多的知识。 二、引导让步状语从句 常放在句首，译作“尽管”、“虽然”，比although或 though语气要轻。例如： 1. While I believe it is true, I cannot prove it. 虽然我相信那是真的，但我无法证明。 2. While any kind of athletic shoe can provide a certain amount of rebound, energy-return sneakers are designed to maximize this effect. 虽然任何一种运动鞋都能提供一定的反弹力，但回力运动鞋能够使这种效果最大化。 三、引导条件状语从句 相当于as long as，译作“只要”。例如： 1. While there is life, there is hope. 有生命，就有希望。 2. While a spark of life remains, it is a doctor’s duty to save the patient. 只要病人还有一息生机，医生就有责任挽救。 四、引导原因状语从句 相当于since， 有“既然”的意思。例如： 1. You’ll never save any money while you’re so extravagant. 你这么奢侈，永远存不下钱来。 2. I’d like to get it settled today while we’re at it. 既然我们着手干了，我想今天就把它干完。 五、连接并列句 表示对比，相当于whereas，译作“而”、“可是”。例如： 1. An outdoors man will soon become pale if he changes to an indoor job, while a desk clerk will take on a tan after a short vacation in the sun. 从事室外工作的人如果调到室内工作，不久肤色就会变白;而一个伏案工作的文员出去度个短假，就会被太阳变黑。 2. Motion is absolute while stagnation is relative. 运动是绝对的，而静止是相对的。 六、连接并列句 表示递进，相当于and what is more, 译作“并且”、“而且”。例如： 1. The new man-made fibres are more hardwearing than natural fibres and greatly reduce mending, while good ready-made clothes are cheap and plentiful. 新的人造纤维比天然纤维耐磨，因此能大大减少修补工作，而且做好的衣服价廉物美，数量也多。 2. Of course, I resolutely determined not to marry, while I quite forgot to consider at all that great rock of disaster in the working-class world-- sickness. 当然, 我下定决心不结婚，而且把工人阶级的巨大灾难——疾病，也忘得一干二净。 （2）neither的用法 1. neither用作形容词，表示“(两者)都不”，置于单数名词之前。 Neither article is made in Beijing. 这两种物品都不是北京制造的。 I will participate in neither game. 那两项比赛我都不参加。 We discussed neither subject.这两个问题我们都没有讨论。 提醒注意：在口语中以not... either...替换neither使用的情形也很多。 例如： They bought neither house. = They didn’t buy either house. 两间房子他们都没买。 2. neither用作代词，表示“两者都不，双方均不”。 例如： He answered neither of the letters. 他两封信都没回。 She bought two toys, but neither can please the child. 她买了两个玩具，却没有一个能让小孩高兴。 —Which one would you like? 你喜欢哪一个？ —Neither. 两个都不喜欢。 此时，与neither用法较为接近的词是none，但none的含义略有不同，none表示“(三者以上)所有的„„都不”。 例如： None of us are perfect. 人无完人。 提醒注意：neither作主语时，通常被视为单数，但从意义上讲也可视为复数。 Neither of the cars was / were damaged. 两部车都没有受损。 3. neither用作连词，常用短语为 neither...nor...，表示“既不„„也不„„”。 例如： Neither he nor I am well educated. 他和我都没受过良好教育。 I have neither time nor money. 我既没时间也没钱。 The novel is neither realistic nor poetic.那部小说既不写实也没有诗意。 提醒注意：①neither和nor后面接同一词性的单词或短语。 ②neither...nor...结构用作主语时，谓语动词必须与nor后面的名词或代词在人称及数上保持一致，即所谓的就近原则。 ③在表示“既„„也„„”，即“两者都„„”时，常用短语both...and...；表示“或者„„或者„„”(即二者选一)时，常用短语either...or...。 4. neither用作副词，作“也不”解释，放在句首，表示前面否定的内容也适用于另一个人或物，句子须采用部分倒装。此时也可用nor替换neither使用。 —I don’t like this dress. 我不喜欢这件连衣裙。 —Neither / Nor do I. 我也不喜欢。 If you don’t suppose the plan, neither / nor will I. 如果你不支持那项计划，我也不支持。 提醒注意：neither之后的主语要置于助动词或系动词之后。
while的使用用法大汇总
我们在学习英语的时候常常会碰到的英语单词，那就是while 了，那么大家知道while 的用法会有哪些呢?你学完了吗?下面，我在这给大家带来while的使用用法大汇总，欢迎大家借鉴参考!
连词“while”具有两种意义，因此为了避免误用，使用时需多加注意。
“while”作为连词来使用的时候，表示“同时性”或“对比性、对立”。根据文章的内容可明确该词具体表达了哪一种意义的情况固然存在，但如同下文中所展示的相反情况同样存在。
The temperature decreased while the growth rate increased.
这句话可产生“温度下降的同时生长速度加快了”和“与温度下降所不同的是，生长速度却加快了”两种翻译。
正解是：若要使后者的翻译成立，“decreased”和“while”之间的逗号必不可少，因此目前的情况下无法直接确定此句的翻译。

例如：
