44.A［考點(diǎn)］推理判斷題

【精析】A根據(jù)第一段最后一句…scratching…andtwitching…areimportantwaysofburningupcalories.，第二段…squirming…andwiggling…equalseveralmilesofslowrunningeachday.和第四段第二句…somepeoplehadburnedup800caloriesintoe-tapping…finger-drumming…andothernervoushabits.可知，研究人員發(fā)現(xiàn)人在坐立不安時(shí)所做的習(xí)慣動(dòng)作能夠幫助消耗卡路里。由此可推知，科學(xué)家們認(rèn)為人在坐立不安時(shí)所做的一些習(xí)慣動(dòng)作是一種減肥的方法。故選A

45.A詞義猜測(cè)題。由littersofpups定位至第二段首句，后面的對(duì)比對(duì)象whohavenobabies實(shí)際上提供了一個(gè)相反的情況，所以我們可以推測(cè)thosewhoraisetwoormorelittersofpups中的littersofpups指的是剛出生不久的小老鼠（babyrats）

46.C［考點(diǎn)］事實(shí)細(xì)節(jié)題

47.D［考點(diǎn)］推理判斷題

【精析】D題干大意是：本文作者想要給人留下一種防竊警報(bào)系統(tǒng)是的印象。根據(jù)第三段第二句…whichiseffective,simpletooperateandeasilyaffordable.可知，這種系統(tǒng)非常實(shí)用，操作簡(jiǎn)單，而且能負(fù)擔(dān)得起。與economical（經(jīng)濟(jì)的，實(shí)惠的）意思最貼近。elementary:初級(jí)的，基礎(chǔ)的；expensive:昂貴的；experimental:實(shí)驗(yàn)性的，均不符合題意。故選D

48.B

49.B［考點(diǎn)］事實(shí)細(xì)節(jié)題

【精析】B根據(jù)第二段最后一句TheArabstookthenewnumbersandmadeimprovementsthatquicklyledtoadvancesintechnology.可知，阿拉伯人采用了新的數(shù)字并對(duì)其進(jìn)行改進(jìn),這帶來(lái)了技術(shù)的進(jìn)步。因此B項(xiàng)正確。阿拉伯人改進(jìn)而不是發(fā)明
