改为 the sloth hangs from trees by its long rubbery
                        limbs, sleeps fifteen hours a day, and moves  so infrequently 算对吗

不對,要改為the sloth hangs from trees by its long rubbery
                limbs, sleeping fifteen hours a day and moving so infrequently

在這裡是無法改成moves,逗號分隔兩個獨立子句,第二個子句要有主詞,and moves明顯違反語法
