He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results.”可知，弗雷德里克ll go away, but I eventually went to the doctor.”可知，作者從小就被灌輸這樣的思維，處理疼痛的更好辦法就是不做任何事情，希望疼痛自行消失，但是卻最終不得不去看醫(yī)生，故可知，作者看醫(yī)生都是迫不得已，故選D。The Alexander technique helps overe posture problems.D.He developed a form of exercise for actors.D.Familiar physical actions shouldn39。The technique shouldn39。s method.D.re walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique.

Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (聲音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teachertraining school, which is still successful today.s oceans will be, on average, at least 60cm higher by the end of the century.”按目前的速度，世界的海洋到本世紀(jì)末平均至少升高60厘米，選D。 （3）考查細(xì)節(jié)理解。故選B。By 2100, the sea level will have risen to a much higher level than now.【答案】 （1）B（2）C（3）D（4）D 【解析】【分析】本文是一篇說(shuō)明文，南極地區(qū)的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。It has uncovered an unknown ecosystem in Antarctica.（4）What can we infer from the last paragraph? A.The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text? A.To explore the geography of the Larsen C ice shelf.（2）What do the underlined words this one in the fourth paragraph refer to? A.s ocean will be, on average, at least 60cm higher by the end of the century. However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg? A.s lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die. The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change, she said. It is important that we get there quickly before the undersea environment changes as sunlight enters the water. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科教類(lèi)閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。故選B。根據(jù)第三段中的“According to Sari Nijssen, the study set out to answer the following question:‘ Under what circumstances would adults be willing to sacrifice robots to save human lives?’可知，在這項(xiàng)研究中，參與者可能必須決定何時(shí)犧牲機(jī)器人。 （1）考查細(xì)節(jié)理解。Robots, A Must for FutureB.Humanized robots offer less help to people.B.where to experience risksC.How to treat them in life.C. According to Sari Nijssen, the study set out to answer the following question: Under what circumstances would adults be willing to sacrifice robots to save human lives? The participants were faced with a hypothetical (假設(shè)的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine. The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (無(wú)名的) humans.How to humanize them.B.when to sacrifice a robotB. words?

One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could e into conflict with their intended function—to be of help to us.可知，Paulus認(rèn)為讓機(jī)器人人性化的嘗試不應(yīng)該走得太遠(yuǎn)，可以推斷出，Paulus認(rèn)為過(guò)多地人性化機(jī)器人可能是不合適的。因此標(biāo)題“機(jī)器人被拯救，人類(lèi)就會(huì)承受打擊”最切題，故選C。 Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one.
