(1) In the late 1950s and 1960s, the national income growth rate of the Soviet Union was relatively high, which was related to the reform measures taken by Khrushchev and Brezhnev when they came to power. However, in the late period of Khrushchev and Brezhnev's administration, the growth rate of national income in the Soviet Union generally showed a downward trend, because neither Khrushchev nor Brezhnev's economic reforms broke through the framework of the original economic system and could not eradicate the accumulated ills.

(2) Khrushchev's economic reform broke through the shackles of traditional ideas to a certain extent, so "one foot of his has entered a new era"; However, Khrushchev's economic reform did not break through the Stalin model, so he said that "the other foot is still mired in the mud of the old times due to historical reasons." Due to the limitation of the times and the defect of personal quality, Khrushchev can only "wander at the crossroads of the old and new times".

When answering the question (1), we should carefully observe the chart, point out the ups and downs of the Soviet national income growth rate, and then analyze the relationship between this ups and downs and the Soviet economic reform in combination with the knowledge we have learned; Question (2) should be analyzed from the perspective that Khrushchev's reform not only broke through the shackles of traditional ideas to a certain extent, but also did not fundamentally break through Stalin's model; Question (3): We can analyze the reasons for the failure of Brezhnev's reform.
