On the plane can break

Fall apart

profit at the expense of others

Day and night

alone and friendless(homeless and helpless)

rest satisfied with one's life

staggering

atone for one's crimes by a good deed

Run out of ammunition and food supplies

can recite quite fluently(easy to pronounce)

a stream of tears

have a facile tongue

pale and thin

leave a good name to posterity

Hold one's breath

green willows and red peach blossoms

a glib tongue

a place very strategically important

take another course(try another tack)

Spring returns after the 12th lunar month is over.
