"The biggest hurdle that I have to overcome is making people believe that even though I am a woman, I am a serious contender," Riley said."I have to remind people that I have competed in two Whitbread races and this is my third America's Cup. I have seen what happens behind the scenes, and I know what it takes to get things done in this kind of environment."

我最大障碍就是说服别人，我虽是女性，却是个认真谨慎的战士』莱丽说『我要不断提醒人们，我参加过二次惠布瑞特、三次世界杯(America's Cup)等多次世界级比赛，我看过前线的仗是怎样打的，我是过来人』。

In these years, I obtain numbers of the contests item of the reward in math and physicses, Including national mathematics The first prize and physics of Beijing the first prizes of contests of league matches, choose school as grades of student having specialty model many times too, But the title of the special aristogenesis of obtaining area is still since the dawn of human civilization the first time.

我的中学生活已经过去快五年了，在这五年之中，我获过很多次数学、物理的竞赛奖项，其中包括了全国数学联赛的一等奖和北京市物理竞赛的一等奖，也被多次评为校级特长生标兵，不过获得区特优生的称号还是有史以来的第一次。

METHODS To count rabbit nictation times,short-time multiple eye drops irritation(once per 15 minute for continuously 2 hours) and long-time eye drops irritation(5 times per day for continuously 4 weeks).

方法计数兔眨眼次数、短期多次给药眼刺激(1次/15min，连续滴眼2h)和长期给药眼刺激(5次/日，连续滴眼4周)作用。

Results Nephroscopic channel was successfully established by one puncture in 13 patients with hydronephrosis and 17 patients without hydronephrosis. For the remaining 15 patients without hydronephrosis, nephroscopic channel was established by repeated puncture. All the patients had no serious complications such as pleural injury, abdominal visceral injury, pyelic laceration and renal penetrating injury.

结果 13例鹿角形肾结石伴积水患者均1次穿刺成功，32例无积水型肾结石患者中17例1次穿刺成功，15例多次穿刺后成功建立理想的取石通道。45例患者均无胸膜损伤、腹腔脏器损伤、肾盂撕裂及肾脏穿通伤等严重并发症发生。

The night before Halloween in 1938, radio listeners were enjoying a broadcast of dance music when an announcer broke in to report that astronomers had seen blue flames shooting off Mars. The program was interrupted again and again, each announcement more alarming than the last. A spaceship had landed on Earth! Tentacled creature-Martians!-were coming out of the ship!

有时候，有害的玩笑也会酿成大祸，不一定非要是愚人节玩笑，也不一定是为了要把人戏弄一番。1938年万圣节前夜，正在收听音乐的人们被一个声音打断，播音员通知说，天文学家观测到火星上有蓝色火焰向外喷射，节目多次被中断，语气一次比一次紧急，&来自火星的飞船已在地球登陆，身披盔甲的火星人已经走出飞船&。

You may have to hit 529 forehands, concentrating on the two key points before it's really grooved into your muscle memory, each person is different, it may be less, it could be more.

你可能必须打击 529次正拍，专注於这二个关键重点，然后真的才可陷入你的肌肉记忆之内，每个人都不同，可能较少次，也可能要更多次。

Sure, he's won a humungous amount of awards for his work (two Academy Awards, three nominations and at least fifty other awards), makes millions of dollars (in 2007, his average wage was $20 million per picture), and is incredibly attractive to the opposite sex (People magazine voted him the sexiest man alive in 1996), but there's a quality he possesses that is more important than any of these: integrity.

的确，他因杰出的影视作品获奖无数（两次奥斯卡、三次提名以及其它五十多次奖项），收入丰厚（2007年，他的平均片酬是2千万美元），并吸引了成千上万的女性（1996年入选《人物》杂志最性感先生），但是他最重要的品质是：正直。

Once or twice, or even up to several times of failure, if I am able to compose a good song, how many times of failure are still worthed!!

一两次，甚至六七次的失败，如果最终制作得到一首好的曲子，再多次的失败也是值得的！！

Several main results on the evolutions of the life and environment on early earth are summarized as follows:(1) the oxygenation of surface environment didn''t cease until a stable stage for 0.4Ga appeared after 1.6Ga;(2) compared to the isotopic compositions of kerogens and coexisted carbonates, the differences between two can effectively carrier the signals from local environments and bio-assemblages;(3) multiple isotopic relationships between kerogens and individual alkanes in Proterozoic samples were observed, which would depend on the specific biogeochemical processes;(4) repeated biogeochemical changes were observed accompanying Neoproerozoic glaciations, which suggesting that environmental rather than evolutionary forces were driving the biogeochemical changes;(5) the bio-radiations after Neoproterozoic glaciations were definitely suggested by molecular and isotopic data to be at the early Cambrian and after the middle of Doushantuo deposition with different triggers for them.

研究获得以下重要认识：（1）古元古代地表环境的氧化可能一直持续到中元古代早期(约1.6Ga)，而在此之后的4亿年里则保持相对稳定；（2）相对于传统的干酪根和碳酸盐的碳同位素组成，二者之差则能更好反映区域环境的演化特征；（3）在元古代干酪根与单体烷烃类之间存在多种碳同位素组成关系；而其与不同的生物地球化学过程有关；（4）全球海洋生物地球化学特征随新元古代多次冰期出现循环波动，这显然为环境因子的驱动；（5）在新元古代大冰期之后，分子与同位素数据显示地球生命在陡山沱中后期和早前寒武纪出现两次大辐射，然而两次生命辐射的本质却是不同的。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
