问题    It has become an obvious truth by now that scientists are not mere knowledge-acquisition machines; they are guided by emotion and intuition as well as by cold reason and calculation. 【F1】Scientiste are rarely so human. I have found, so at the mercy of their fears and desires, as when they are confronting the limits of knowledge. The greatest scientists want, above all, to discover truths about nature (in addition to acquiring glory, grants, and tenure and improving the lot of humankind); they want to know. They hope, and trust, that the truth is attainable, not merely an ideal, which they eternally approach.
   Scientists who harbor this belief are often accused of arrogance. Some are arrogant, supremely so. But many others, I have found, are less arrogant than anxious. These are trying times for truth seekers. Moreover, science itself, as it advances, keeps imposing limits on its own power.
   For the most part, strong scientists have only one option: to pursue science in a speculative, post empirical mode that I call ironic science. 【F2】Ironic science resembles literary criticism in that it offers points of view, opinions, which are, at best, interesting, which provoke further comment. But it does not converge on the truth. It cannot achieve empirically verifiable surprises that force scientists to make substantial revisions in their basic description of reality.
   【F3】As empirical science become stereotyped, journalists such as myself, who feed society’s hunger, will come under more pressure to promote theories that supposedly transcend the big bang theory or natural selection. Journalists are, after all, largely responsible for the popular impression that fields such as chaos and complexity represent genuinely new sciences superior to the dull old reductionist methods of Newton, Einstein and Darwin. 【F4】Journalists, myself included, have also helped quantum (量子) theories of consciousness win an audience much larger than they deserve given their poor standing among professional neuroscientists.
   I do not mean to imply that ironic science has no value. Far from it. At its best ironic science, induces wonder in us; it keeps us in awe before the mystery of the universe. But it cannot achieve its goal of transcending the truth we already have. 【F5】And it certainly cannot give us—in fact, it protects us from—The Answer, a truth so potent that it quenches our curiosity once and for all time. After all, science itself decides that we humans must always be content with partial truths.
【F3】
选项
答案随着经验主义科学的僵化，像我这样满足社会需求的记者们，需要顶着更大的压力来兜售那些似乎超越了宇宙大爆炸理论或是自然选择学说的理论。
解析 ①本句是多重复合句。主句主干为journalists such as myself will come under more pressure；句首的As引导主句的时间状语从句，表示“随着……”。②who引导定语从句修饰主句主语journalists。③to promote theories…作后置定语，修饰pressure；that引导定语从句修饰先行词theories。④the big bang theory应理解为普通术语“宇宙大爆炸理论”。
