124. Found throughout Central and South America,
sloths hang from trees by long rubbery limbs and
sleep 15 hours a day, moving infrequently enough
that two species of algae grow on its coat and
between its toes.
(A) sloths hang from trees by long rubbery limbs and
sleep 15 hours a day, moving infrequently enough
(B) sloths hang from trees by long rubbery limbs,
they sleep 15 hours a day, and with such
infrequent movements
(C) sloths use their long rubbery limbs to hang from
trees, sleep 15 hours a day, and move so
infrequently
(D) the sloth hangs from trees by its long rubbery
limbs, sleeping 15 hours a day and moving so
infrequently
(E) the sloth hangs from trees by its long rubbery
limbs, sleeps 15 hours a day, and it moves
infrequently enough

这道题，为什么选择D我已经弄懂了，但是我反过来再看，觉得
既然D可以用  do, doing and doing 的结构，那么A中的 do and do,doing  这种结构正确吗？

从语义上来分析，hang在树上，然后伴随而来的是睡15个小时，还有基本不动弹。这三个动作间的逻辑语义原文已经暗示出，不能随意改动！
