颞颌关节炎如何热敷:子宫日记（1）

In the womb 1

     This baby has come to the end of a nine-month-long journey. She can already taste, hear, smell, touch and learn. After 266 days, her soft cocoon(茧) has grown increasingly cramped and uncomfortable and there is only one way out into an unknown world of bright lights, loud noises and cold air, and there is no turning back.

       孩子进入了九个月旅行的最后时刻，她已经学会了感觉、聆听、嗅探、触摸和学习。在266天之后，裹着她的外衣变得越来越紧，越来越不适合她的身体。唯一的出路就是从妈妈的肚子里钻出来，进入一个未知的世界，一个充满着闪耀的灯光、嘈杂的声音和冰冷空气的世界，而且绝无退路。

      This is her story, as seen from inside the mother’s womb, from the moment two cells fuse into one to the birth of a baby girl in just nine months.

       这个故事发生在妈妈的子宫里，故事从两个细胞结合开始，直到孩子在九个月后出生时才结束。

      This baby is about to begin the journey of a lifetime, having spent nine months hidden in her mother’s womb. In just 38 weeks, she’s transformed from a single cell into trillions with over 200 specialized types, organized into the incredibly complex form of an infant girl.

       宝宝马上就要开始她自己的生命之旅，结束在妈妈子宫里的九个月生活。在38周之后，她已经从一个单细胞转变成由几十亿个形态超过两百种的多种细胞组成的女婴。

        Using new 3D and even 4D scanning techniques, a window has opened on the womb, allowing us to see fetal development unfold before our eyes. Real footage and computer imagery based on scientific observation take us on a journey inside the womb as it’s never been seen before and reveal that the fetus behaves in a much more complex way than previously imagined. During her odyssey(长期的冒险旅行) in the womb, she will smile, recognize the shelter and the basics—food, water and oxygen, but the real star of the show is the fetus herself, building, dividing and growing according to an intricate set of plans created at the moment of conception.

       使用最新的3D甚至4D彩超技术后，子宫就好像被打开了一扇窗，让我们可以清晰地看到胎儿的进化。用于科学观察的真实影像技术和电脑成像技术让我们可以在子宫里旅行，而之前从未有过这样奇妙的经历，因为我们看到胎儿在发生着难以想象的变化。在子宫里的长期冒险旅行中，胎儿会微笑，能找到它睡觉的屋子，甚至能认出自己赖以生存的东西——食物、水和氧气。当然胎儿本身才是这个故事的主角，受精后它将按照预先的计划变成一个健康的宝宝。

    Here is how it begins, during ejaculation(射精), a mature healthy man expels up to 500 million sperm inside a woman’s vagina(阴道). Each sperm carries a precious cargo—the father’s genetic code. A man’s testes(testis的复数，睾丸) are constantly at work, churning out over a thousand sperm every second. The quality of these sperm depends on the man’s lifestyle. If you avoid smoking, excessive alcohol, hot bath, even tight underwear, you will produce stronger, healthier sperm.

       现在我们就来说说故事是怎么开始的吧。射精时，一个成年健康男性可以向女性的阴道射出多达五亿个精子。每个精子都携带着一样重要的东西——父亲的遗传密码。男性睾丸在射精时会一直运动，每秒钟射出超过一千个精子。精子的质量取决于男性的生活习惯。如果能够拒绝吸烟，拒绝酗酒，不洗热水澡，不穿很紧的内裤，就可能获得强壮而健康的精子。

    Coffee, on the other hand, appears to stimulate sperm to swim further, faster and harder. It’s a slow journey for the sperm, the smallest cell in the human body. They travel one tenth of an inch per minute and there are hurdles at every turn. From the vagina, they pass through the cervix(子宫颈), up into the uterus(子宫), and on into the fallopian tube(输卵管) where the woman’s egg, the largest cell in the body, awaits.

       研究也发现，咖啡可以让精子游得更远、更快、更持久。对于精子来说，进入阴道后的行程是一个漫长旅行，因为它们是人类身体里最小的细胞。它们每分钟只能前进 0.1英寸，而且在每一个拐弯处还有很多障碍物会阻止它们前进。进入阴道后，它们要通过子宫颈，到达子宫，再进入输卵管，那里正有人类最大的细胞——女性的卵子在等着它们。
