C。 Solve by elimination.

First of all, I'd rather live less than 2 years, and I'd rather try my best to win a big oil field. I'd rather work hard and keep the oil field stable and high-yield. These two sentences don't reflect how bold people are and how productive the land is, so I rule out two items.

let's talk about the fourth item. It is wrong to say that hard work is the unique spirit of a unique era. Hard work is not unique to a special era.

Extended information:

"With a blue sky above my head and a waste land on my feet, I was full of patriotic pride, and I got rid of the label of' poor oil and backward' in one fell swoop, and won large oil fields at a high speed and at a high level, creating a miracle in the development history of China's oil industry." The introduction of the narrator of the Iron Man Wang Jinxi Memorial Hall to the tourists is a true portrayal of the oil workers at that time.

on October 8, 1923, Wang Jinxi was born into a poor peasant's family in chijinbao, Yumen county, Gansu province. In 195, Wang Jinxi entered Yumen Oil Mine, became the first generation of drilling workers in New China, and began to devote himself to the oil industry of the motherland.

on April 29th, 1956, Wang Jinxi joined the China * * * production party. Shortly after joining the party, he served as the captain of the "Bewu 5 Team". In September, 1958, Wang Jinxi led a team to create a national drilling record with a monthly footage of 5,9 meters, and was known as the "Steel Drilling Team".

in February, 196, the Central Committee of China * * * approved the report of the former Ministry of Petroleum Industry on organizing the oil battle in Daqing, and concentrated elite soldiers from Yumen, Sichuan, Xinjiang, Qinghai and other oil plants, mines, universities and scientific research departments in Daqing.
