00 Here's the poem, the questions; answer follow. 02br
00 Stopping By Woods On A Snowy Evening Whose woods these are I think I know.02br
00His house is in the village though;02br
00He will not see me stopping here02br
00To watch his woods fill up with snow.02br
02br
00My little horse must think it queer02br
00To stop without a farmhouse near02br
00Between the woods and frozen lake02br
00The darkest evening of the year.02br
02br
00He gives his harness bells a shake02br
00To ask if there is some mistake.02br
00The only other sound's the sweep02br
00Of easy wind and downy flake.02br
02br
00The woods are lovely, dark and deep.02br
00But I have promises to keep,02br
00And miles to go before I sleep,02br
00And miles to go before I sleep. Stanza # 04(All the questions below are related to Stanza No. 4) 02br
00Why can’t the poet wait to enjoy the beauty of the woods? 02br
00He can’t wait to enjoy the beauty of the woods, because he has too many responsibilities to fulfill, and has a long distance to travel before he can rest for the night. 02br
00Why does he repeat the third line? 02br
00He repeats the third line in order to imprint it on the reader’s memory, as well as to foreground the presence of a non-literal meaning, but not the meaning itself. In other words, the repetition gives the reader of the poem the opportunity to go beyond the literal into the figurative. Furthermore, the poem has a strict rhyme scheme. The first three stanzas go: aaba bbcb ccdc. Three lines rhyme; the line that doesn't rhyme provides the rhyme for the next stanza. There are just enough stanzas to establish a pattern. The fourth stanza is the last. Since there is no stanza after the last one, the third line cannot have a none-rhyming line. Now, instead of having just three lines, or just four rhyming lines, the poet chose to repeat the last line. This gives a powerful feeling of "closure"; not only is there no new rhyme, there isn't even a new line. The first "sleep" disrupts the expectation (we would expect a non-rhyming line); the repetition wraps up the poem. 02br
00Which letters have been repeated in the last stanza? 02br
00Since the rhyme is [...i: p] in the last stanza, the repeated letters that are most obvious would be: "e" (as "ee", sounding ; it also appears in "lovely" or "promises", but the letter sounds differently there) and "p". It's true that the letter "o" is also repeated a lot, but it sounds differently in "woods", "to", "lovely" and "promises". 02br
00Why have they been repeated? 02br
00They might have been repeated to produce a profound impression.02br
