Martin was returning to work in his London office after spending two weeks with his brother over in New York. He was coming back with a heavy heart. It was not just that it was the end of a wonderful holiday; it was not just that he invariably suffered badly from jet lag; it was that Monday mornings always began with a team meeting and, over the months, he had grown to hate them. Martin was aware that colleagues approached these meetings with hidden agendas; they enjoyed game-playing, and he knew that people were not being honest and open. The meetings themselves were bad enough-but then there was all the moaning afterwards. "The usual people say the usual things." "I could have improved on that idea, but I wasn’t going to say." "I was thinking of making a suggestion—but I couldn’t be bothered." As this morning’s meeting began, Martin braced himself for the usual moroseness (闷闷不乐) and monotony. But, as the meeting progressed, he became aware of a strange background noise. At first, he thought that he was still hearing he engine noise from the aircraft that had brought him back to London—he had had to sit over the wing and the noise was terrible. But, as he concentrated on the noise, it became a little clearer. He realized—to his amazement—that he could hear what his colleagues were thinking as well as what they were saying. As he concentrated still harder. He found that he could actually hear what they were thinking at the same time as they were speaking. What surprised him, even more than the acquisition of this strange power, was that he discovered that what people were saying was not really what they were thinking. They were not making clear their reservations. They were not supporting views which they thought might be unpopular. They were not contributing their new insights. They were not volunteering their new ideas. Martin found it impossible not to respond to his new knowledge. So he Started to make gentle interventions, based more on what he could hear his colleagues thinking than on what he could hear them saying. "So, John, are you really saying..." "Susan, do you really think that" "Tom, have you got an idea on how we could take this forward" He was aware that his colleagues were unsettled by how insightful these interventions were. They looked at him mystified. In truth, he felt rather proud of his newly-acquired talent. Given more confidence now, Martin forgot his usual misery at participating in such meetings and began making comments of his own. However, he became aware that some of his colleagues were looking at him totally confused. One or two even had a gentle smile playing on their lips. Only gradually did it dawn on them—he could hear their thoughts and they were not really saying what they were thinking. As the meeting progressed, Martin became aware of changes to the tone and style of the event. It was clear to him now that, one by one, each member of the meeting was learning how to hear the thoughts of all the others and this was subtly changing how they interacted with one another. The game-playing started to fall away; people started to speak more directly; views became better understood; the atmosphere became more open and trusting. The meeting ended. As people left the room, Martin found that he could still hear what they were thinking. "That was the best meeting we’ve ever had." "All meetings should be like that." "In future, I’m going to say what I think." Which of the following is nearest in meaning to "braced him self for" in Paragraph 3

A. prepared himself for
B. adapted himself to
C. concerned himself about
D. persuaded himself into
