For hundreds of millions of years, turtles have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings down to the water's edge lest they become disoriented by headlights and crawl towards a motel parking lot instead.

在数亿年前的时间里，海龟一直在挣扎着离开大海道海滩上产卵，时间远远遭遇自然纪录片的赞扬，或全球定位通讯卫星和海洋生物学家的追踪，又或者志愿者们用手把幼龟放在海边以避免它们受到光线的影响迷失方向，爬向汽车旅馆的停车场。

早在人类有自然纪录片称颂海龟、GPS卫星和海洋生物学家对其进行追踪或者志愿者用手将幼龟捧到海边以免他们因为桅灯迷失方向而爬向汽车旅馆的停车场之前的数亿年，海龟一直是艰难地爬出海面到沙滩上产卵的。

Seeing a fish fall off the radar for a few hours, the researchers try to correlate its trek with events in the region, such as the annual spring herring spawn (a welcome source of food for many Prince William Sound regulars).

发现一条鱼从雷达上消失了数个小时后，研究者们设法将它的行踪同区域性的事件联系起来，比如每年一度的春季鲱鱼产卵期（鲱鱼卵对于在威廉王子湾栖息的生物来说是非常受欢迎的食物）。

Chinese alligator eggs and reproductive environmental factors have been investi gated from 1998 to 2005 in the Anhui Research Center for Chinese Alligator Reproduction.

在1998~2005年对扬子鳄繁殖研究中心内自然环境下鳄卵及其繁殖地环境因子进行调查，包括窝卵数、产卵时间、出壳时间、孵化期内温度、湿度的变化情况、雏鳄孵出后的存活数量以及巢区的植被盖度。

The ordinary clutch size of Great Tit is ten or eleven. The ordinary laying date is ten days or eleven days.

大山雀的常见窝卵数为10枚和11枚，最常见的产卵期为11天和10天。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
