一次

Madonna remembers: When I came to New York it was the first time I'd ever taken a plane, the first time I've ever gotten a taxi-cab, the first time for everything.

麦当娜回忆道：我刚来纽约时，是我头一次乘飞机，头一次搭乘出租车，什么都是头一次。

Beginning 10 days after the initial internal urethrotomy, the second group had urethral dilations with Benique dilatators (maximal 21F) under intraurethral anesthesia, weekly for the first month, once after three and after six months, and then annually.

在最初接受内视镜尿道造口术后的10天内，第二组利用Benique扩张器(最大 21F)，在麻醉下进行尿道的扩张，首先第一个月是每周进行一次，在来分别在3个月后和6个月后各进行一次，然后每年进行一次。

This time u take back what is urs, this time it is he who is surprised, this time it is u who smile.

But they had to make it, and immediately, for it brooked no delay.

每选择一次，就放弃一次，遗憾一次。

More than 90% of East Asian haplotypes could be found in either Southeast Asian or Central-South Asian populations and show clinal structure with haplotype diversity decreasing from south to north.

人们曾经就亚洲移民活动是通过两起殖民浪潮（一次是向东南亚的移民以及后来的向中亚和东北亚的一次移民），或是仅仅只有单独一次的人群迁徙存在着争论。

In fact, it had gotten to the point of me disliking many of my trips (even though I pushed myself to do it again).

事实上，这已经让许多次的旅行让我产生一种厌恶的感觉（即使这样，我还是逼迫自己一次一次的去再这么做）。

The Emei still line or two lines, KISSY and his or LG for reasons such as not traveling with us every time they travel, we could not step on the same rhythm, But every time I was an executive discretion to inform them every time the first time, each time by a disappointing end, it turned out, however small they expressed surprise over the warm, and very willing to join us along side there is no coincidence, I notice They had a few days later, accompanied by special ticket packages and did not, had no choice but to the next.

的峨眉仍然行或两行，基西和他或LG电子的原因，如没有随同我们每一次他们的旅行，我们不能一步就同一节奏，但每次我是一个行政自由裁量权，告知他们每一次的第一次，每次由一个令人失望的结束，事实证明，无论多么小，他们感到惊讶的热情，和非常愿意加入我们的行列旁边没有巧合，我发现他们在几天之后，伴随着特殊的机票套，也没有，没有别的选择，只能下次。

The outer neuroblastic layer before it divided to inner and outer nuclear layer and outer complexiform layer and gonglion cell layer showed a temporal PCNA positive which was related to proliferation. The three cell layers had another PCNA positive when finished time changed from outer to inner after their morphologic development basically completed( outer nuclear layer:11～15 days,inner nuclear layer: 8～16 days, gonglion cell layer:16～21 days).

PCNA显示在外成神经细胞层分化为内、外核层和外丛状层之前，和节细胞各有一次和增殖相关的阳性表达。3个细胞层在形态学的分化基本完成后，又出现了一次结束时间是由外向内变化的阳性过程（外核层：第11天至15天：内核层：第8天至16天，神经节细胞层： 16天到21天，这一次阳性表达过程可见到细胞形态向成年形态的转化。

Neddleless to say, this successful spoken English contest is undoubtfully helpful to test each English teachers' teaching level, to highlight each student's standard and efficiency of English study, to impact each participant's awareness of participating, working together and competing, which certainly has a deep effect on our campus culture.

这次比赛，既是对我们高中部英语教师教学水平的一次集中检验，也是我们高中部全体同学英语学习水平和学习成效的一次精彩展出，同时也是对我们全体师生参与意识、集体意识和竞争意识的一次有效检阅，它一定会对我们的校园文化产生深远的影响。

The same scene repeated again and again. All started with roar of tank engine, climaxed when forces of steel and fleshes colliding at opposite side of the bus, ended with joys of thunder when tank backed off...….

接着是双方一次又一次的重复较量，每一次都是以坦克的巨大马达声开始，以双方同时涌向车牆的壮观景象而达到高潮，最后在坦克的后退和人们胜利的欢呼声中结束。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
