题目

下列叙述中,与毛.泽东诗句描述的“坐地日行八万里”情形最相吻合的是A.赤道处的线速度 B.30°纬度处的线速度C.60°纬度处的线速度 D.任何纬度,因为诗句描述的是地球公转线速度 答案：【答案】A【解析】考查地球自转速度。“坐地日行八万里”即四万千米，结合地球赤道周长约4万千米。而地球自转线速度自赤道向南北两极递减，故“坐地日行八万里”表示赤道上的线速度，A正确。故选A。 第二节 完型填空（共20小题；每小题1.5分，共30分） 阅读下面短文，掌握其大意，然后从36—55各题所给的四个选项（A、B、C和D）中，选出最佳选项        It was in late April, dangerously near the well – known AP exams, when the absurdity(无助的荒诞感) of my life struck me.

After -  school arrangements had already worn away my   40  . To keep myself awake at 11p.m. to finish five hours of   41   just seemed like too much to handle. I   42   at the computer screen with tears streaming down my cheeks,   43  my friend James about how stressed out I was over school.        His response was immediate. “Well,   44   did you decide to take five AP classes on the top of everything you’re doing?”        My response   45  just as quickly. “Because I need them for college. Harvard won’t   46   someone who doesn’t challenge themselves with difficult classes!”        The words sounded so   47   as I typed them on the screen that I   48  laughed out loud. I was supposed to be   49  myself not torturing(折磨) myself. That was the night I   50   that I didn’t need to deal with a course load of disastrous difficulty to   51   my own self – worth.        It was a little too late to   52   things, of course. The AP exams were about to go full – force,   53   were winding down, and most of my clubs and organizations were about to hold their end – of – year parties. Still, I   54  a valuable lesson. No college, one billion dollar endowment (资助) or not, is worth the   55   I went through last year. I wish I’d had someone to tell me sooner that I didn’t have to do everything. Colleges don’t really want overachieving robots, They want people with passion(love). It doesn’t matter whether you’re a policy debater or not, as long as you show that you’re going for the things you love. 36．A．list        B．box       C．film      D．car 37．A．listened to B．put up      C．looked at  D．found out 38．A．working   B．fighting    C．struggling D．studying 39．A．physical    B．nervous    C．constant    D．mental 40．A．patience    B．sense     C．energy      D．evidence 41．A．sleep     B．homework       C．essays       D．tests 42．A．knocked   B．pointed     C．stared       D．shouted 43．A．typing      B．messaging C．ealling      D．telling 44．A．who      B．what      C．how      D．why 45．A．received   B．made     C．showed     D．came 46．A．want     B．teach     C．meet      D．respect 47．A．curious     B．ridiculous C．encouraging     D．disappointing 48．A．still       B．also       C．almost      D．even 49．A．admiring  B．inspiring   C．educating  D．ehallenging 50．A．realized    B．doubted    C．believed    D．guessed 51．A．know           B．prove           C．become     D．trust 52．A．keep      B．collect      C．change      D．forget 53．A．classes      B．exams       C．students    D．operations 54．A．had       B．learned     C．gave      D．took 55．A．plans      B．lessons      C．hardship   D．stress
