15、Just half a dozen holiday-makers have reachedorbit since then, for similarly astronomical price tags.(從那之后，只有6個度假者到達了太空軌道，價格也同樣是天文數(shù)字。)
16、Changes in the eccentricity of Earth'sorbit occur in a cycle of about 96,000 years.(地球軌道偏心率的變化大約在96000年的一個周期內發(fā)生。)
17、Unlike earlier lunar missions, Clementine didn'torbit only around the moon's equator.(不像早些時候的月球探測那樣，克萊門飛船并不是僅僅沿著月球的軌道飛行。)

19、The government is more focused on preventing new debris from forming than taking the trash out oforbit.(政府更關注的是防止新的碎片形成，而不是把垃圾帶離軌道。)
20、As it lost weight, it started to incline itsorbit toward the earth: it was dangerous, above and beyond anything else.(當它失重的時候，它開始將它的軌道向地球傾斜：這是危險的，比其他任何東西都危險。)
21、This kind of periodicorbit is only a phase in a comet's life.(這種周期性軌道只是彗星生命中的一個階段。)
22、One characteristic of Earth'sorbit is its eccentricity, the degree to which theorbit is an ellipse rather than a circle.(地球軌道的一個特點是它的離心率，也就是軌道是橢圓而不是圓形的程度。) 【hao86.com好工具】
23、The shape of thisorbit isn't consistent; it varies over time, over a period of about a thousand years.(軌道的形狀并不是始終如一的；它會隨時間變化，變化周期為一百年左右。)
