2. Describe the similarities and differences of these two roads. Which one does the speaker take? 
Two roads are similar except one of them is more “grassy,” which implies that it is less traveled by people. The speaker prefers the less traveled one, because he likes adventure. 
3. What might the two roads stand for in the speaker's mind?    
One road stands for the traditional one and the other is unconventional one and full of challenges and difficulties. To follow other people's footsteps or to open a new road for himself is really not an easy decision for us to make in our lives.

Langston Hughes
(1)Dreams
1. Why must we stick to our dreams?
If God is not the first move in our life, surely our dreams are the same. 
 2.What images does the poet employ to describe the life once we lose our dreams?
Without dreams our life will be a broken bird and a barren field. I think without dream our life will be a grand ship drifting on the vast ocean, never knowing its destination. 
(2)Me And The Mule
1. Why does the speaker identify himself with the mule?
They share a lot in their life: hard-working and full of strength, submissiveness and kindness and honesty. 
2. What figure of speech does the poet employ in describing the mule?
Personification.
(3)Border Line
1.Paraphrase this short poem, using your own words.
I often contemplated the basic difference about life and death, but found out that there are no real differences between the opposite concepts. The difference only lies in degrees. I often thought about this world and the world after death, yet realized that they are actually the same.
2.What is the theme of this poem?
The poem is a protest against the racial discrimination and oppression in American society.
3. Do you think the tone of the poem optimistic or pessimistic?
It is on the whole pessimistic, because the speaker finds the life of an American Negro is no better than a living death.
