句意：有些人的动力来自对成功的需要，而有些人的动力来自对失败的恐惧。
because因为；if如果；unless除非；while尽管；然而；当……时。
此处表示对比，相当于whereas，译作“而”。
故选D项。
【点睛】连词while有以下不同的作用和含义：一、引导时间状语从句时，译作＂当……时＂。
如：1. Make hay while the sun shines. 烈日当空照，勿忘晒干草。
（乘机行事，抓紧时机。
）2. We must work hard to gain more knowledge while we are young. 趁着我们年轻，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。
如：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。
三、引导条件状语从句。
相当于as long as，译作＂只要＂。
如：1. While there is life, there is hope.只要有生命，就有希望。
2. While a spark of life remains, it is a doctor’s duty to sav e the patient. 只要病人有一息生机，医生就有责任救他。
四、引导原因状语从句。

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＂。
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，就会被太阳晒黑。
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＂。
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．The newly-married couple quarreled so much that they reached the point _______ they had to separate from each other.A．when B．where C．which D．that【答案】B【解析】定语从句考查题。
先行词是the point为抽象的地点，关系词where在从句中做状语。

I could have been here sooner是和过去事实相反的虚拟语气，四个选项中只有otherwise可以充当含蓄虚拟条件，相当于if I had not got caught in the traffic.所以选D。
4．Dad thinks I should study to be a doctor，____ I’m not interested in medicine.A．so B．and C．but D．for【答案】C【解析】so因此；and而且；but但是；for因为。
根据句意，可知选C。

句意：我们所有的设备都可以追溯到20世纪60年代和70年代；除非我们能买到必要的技术，否则我们不能生产与外国产品相竞争的产品。
A. unless除非；B. while 当…时候；C. once一旦；D. if如果。

分析句子可知，本句缺少从属连词，根据句意，before符合句意。
故A选项正确。
【点睛】before可以表达的意义。
1. before作为连词时的基本意义是“在……之前”，用于表示时间或顺序。
2. 表示“过了多久才……”，说明主句的持续时间比较长而从句的动作缓缓来迟。
3. 表示从句动作还没来得及发生或完成，主句动作就已经发生或完成了，意为“尚未……就”，“没来得及……就”。
4. 表示“以免，以防，趁……还没有……”，强调动作的必要性，以避免或防止从句动作的发生。
5.用于“It will be/would be＋一段时间＋before…”句型中，表示“还要过多长时间才……”；用于“It was＋一段时间＋before…”句型中，表示“过了多长时间才……”，强调时间的“长”。
6. 用于句型“It won’t be/was not＋一段时间＋before…”中，意为“不久就……”，“没过多长时间就……”，强调时间的“短”。
分析句子可知，本句缺少从属连词，本句中的before表示“尚未……就”，“没来得及……就”，所以，A选项符合句意。
故A选项正确。
