Lesson 23-1 Bird flight
No two sorts ofbirds practise quite the same sort of flight; the varieties are infinite; buttwo classes may be roughly seen. Any ship that crosses the Pacific isaccompanied for many days by the smaller albatross, Which may keep company withthe vessel for an hour without visible or more than occasional movement ofwing. The currents of air that the walls of the ship direct upwards, as well asin the line of its course, are enough to give the great bird with its immensewings sufficient sustenance and progress. The albatross is the king of thegliders, the class of fliers which harness the air to their purpose, but mustyield to its opposition. In the contrary school, the duck is supreme. It comesnearer to the engines with which man has 'conquered' the air, as he boasts.

练习感悟：这篇文章，由于有些原因，导致我练习的时间与录音的时间有点脱节，所以读起来有点生疏的感觉，不过整体还行吧，录了四遍左右达标，语音语调方面感觉就不怎么样了。
