1。 A/ The new economic policy mentions allowing small and medium-sized enterprises to be privatized, correcting the shortcomings of the "wartime communist policy", resuming market transactions, and making full use of the market to develop the economy. Because the new economic policy is Lenin's initial exploration of the communist road, it has not yet reached the socialist market economy, and it can only be regarded as a prototype at most, so B is excluded.

2。 D Stalin model contributed the most to Soviet industrialization, which was defined as a highly centralized political and economic system. The single public ownership of the means of production is the basis for the Soviet Union to form a highly centralized planned economic system. The west mainly relies on private accumulation. The Soviet Union gave priority to developing heavy industry rather than focusing on it, so it ruled out A and B. Under the background of Stalin's model, the Soviet Union's agriculture was initially mechanized, and obviously there was no lag, so it ruled out C.

(1) On the left is Khrushchev of the Soviet Union and on the right is President Kennedy of the United States.

(2) The fierce contest is to win a new round of arms race, so as to dominate the world by one's own efforts, instead of just staying in the bipolar pattern of hegemony with the United States and the Soviet Union.

(3) The US-Soviet hegemony is divided into three stages. At this stage of Khrushchev and Kennedy's life, the Soviet Union tried to dominate the world with the United States, but the United States still dominated. The Soviet Union strengthened its control over Eastern Europe, staged the Cuban missile crisis that shocked the world, attempted to intimidate the United States by force, and was finally forced to withdraw its troops under the threat of American war. The result is that the two sides are evenly matched and the world is relatively stable. If we look at the whole pattern of hegemony between the United States and the Soviet Union, the Soviet Union disintegrated and the Warsaw Pact was dissolved. The consequence is that the world pattern has evolved from a bipolar pattern to a multipolar trend.
