In 1915 Einstein made a trip to Gottingen to give some lectures at the invitation of the mathematical physicist David Hilbert. He was particularly eager -- too eager, it would turn【B1】-- to explain all the intricacies of relativity to him. The visit was a triumph, and he said to a friend excitedly, "I was able to【B2】Hilbert of the general theory of relativity."
【B3】all of Einstein's personal turmoil (焦躁) at the time, a new scientific anxiety was about to【B4】. He was struggling to find the right equations that would【B5】his new concept of gravity,【B6】that would define how objects move【B7】space and how space is curved by objects. By the end of the summer, he【B8】the mathematical approach he had been【B9】for almost three years was flawed. And now there was a【B10】pressure. Einstein discovered to his【B11】that Hilbert had taken what he had learned from Einstein's lectures and was racing to come up【B12】the correct equations first.
It was an enormously complex task. Although Einstein was the better physicist, Hilbert was the better mathematician. So in October 1915 Einstein【B13】himself into a month-long frantic endeavor in【B14】he returned to an earlier mathematical strategy and wrestled with equations, proofs, corrections and updates that he【B15】to give as lectures to Berlin's Prussian Academy of Sciences on four【B16】Thursdays.
His first lecture was delivered on Nov. 4, 1915, and it explained his new approach,【B17】he admitted he did not yet have the precise mathematical formulation of it. Einstein also took time off from【B18】revising his equations to engage in an awkward fandango (方丹戈双人舞) with his competitor Hilbert. Worried【B19】being scooped (抢先), he sent Hilbert a copy of his Nov. 4 lecture. "I am【B20】to know whether you will take kindly to this new solution," Einstein noted with a touch of defensiveness.

SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： Let's look back in history to an earlier way of life. At one time, children didn't have to learn any more than how to cope with their physical environment. They had to learn to be careful around moving objects, to draw back when they got too close to something dangerous. They didn't need a special school to learn these things other than the school of experience, nor was school necessary for them to learn how to survive. Because their parents taught them all they needed to know about how to hunt and to till the soil. But as the society became more complex, people depended more on others who were living far away. So it became important for children to learn to read and write. When money was created, they needed to learn to count and calculate. Children had to know there things in order to survive in this new expanded environment. Because such skills could not be learned simply from first-hand experience, schools became necessary so that children could be taught what we now call the three Rs: reading, writing and arithmetic.
In the earliest times, children needed to learn ______.
