Third, write Ode to Lyme silently and fill in the blanks according to the poem.

The author of this poem is Yu Qian of the Ming Dynasty. The first sentence says that it is (hard or not easy) to mine limestone, which means that lime must be fired from the beginning (after a lot of tempering). The second sentence "Fire burns us" is in sharp contrast to "Idling around", which sets off lime (unyielding and leisurely quality). In the third and fourth sentences, the poet determines that he is a (pure and innocent) person.
