The answer to the second question, who can do it, it is best to talk about both cases

Self-improvement: The sunset sings instead of writing the scene and directly inherits the second sentence, vividly showing the poet's spirit of active use of the world. "Sunset" is actually a metaphor for the twilight years, compared with "Autumn Wind and Sickness", showing the poet's mental state of being in adversity but full of strength.

Resentment: "Old horse" is the poet's self-comparison, "long-distance" refers to the power of galloping, the poet pointed out (the ancients saved the old horse, not to take its strength, but to use its wisdom) although I am a "rotten Confucian", but the heart is still strong, sick and sick, like the old mother, not without a little use. The implication is:

Am I really a useless rotten man, not even as good as an old horse? The injustice of seeing the abandonment of nostalgia is naturally revealed.

1. Filled with the spirit of the poet's unremitting self-improvement:

Although the poet said that he was a rotten Confucian in the world, he wandered everywhere like a cloud, but "the eternal night and the moon are lonely" shows that his noble heart has not changed; The neck couplet and tail couplet can especially show the author's strong and unyielding spirit: although he is in his twilight years, he is full of strength; The autumn wind is bleak, but the poet feels that his illness is getting better; Although the old horse cannot run long distances, it can still function. The whole poem is high-spirited, lonely but not decadent, reflecting a positive and unwilling mental state.

Second, it expresses the poet's resentment:

The poet's indignation can be said to run through the poem. In the first couplet, the poet says that he is a corrupt Confucian, implying a resentment that cannot be used by others; The jaw couplet uses Yunyue as a metaphor to express the frustration of his noble character but his life experience is scattered; In the neck couplet, the poet said that he was not strong, but he was unexpectedly regarded as an "old horse" and thought that he could not gallop long distances, and the feeling of frustration and loneliness was obvious, and the feelings of resentment overflowed between the lines of the poem.

Sliding friction does negative work.

Let a(x1,y1) and b(x2,y2), which is meant by the titleoaob=0, i.e., x1x2+y1y2=0

Bringing y=kx+1 into the hyperbolic equation yields 3x -(kx+1) -1=0, which is simplified to obtain (3-k) x -2kx-2=0

Discriminant = 4k +8(3-k) = 24-4k 0, i.e. k 6

x1x2=-2/（3-k²），x1+x2=2k/（3-k²），y1y2=（kx1+1）（kx2+1）=k²x1x2+k(x1+x2)+1=1

And x1x2+y1y2=0, so 1-2 (3-k)=0, so k=1, k=1
