Question

10．Science can't explain the power of pets，but many studies have shown that the company of pets can help lower blood pressure （血壓） and raise ch ances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tell you how much joy a pet brings．For some，an animal provides more comfort than a husband/wife．A 2002 study by Karen Allen of the State University of New York measured stress （緊張） levels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic （算術(shù)） or held a hand in ice water．Subjects completed the tasks alone，with a husband/wife，a close friend or with a pet．People with pets did it best．Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates．With pets in the room，people also made fewer math mistakes than when doing in front of other companions．It seems people feel more relaxed （放松）around pets，says Allen，who thinks it may be because pets don't judge．
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits．Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs； a separate group of 56 people without pets were put on a diet program．On average，people lost about 11 pounds，or 5% of their body weight．Their dogs did even better，losing an average of 12 pounds，more than 15% of their body weight．Dog owners didn't lose any more weight than those without dogs but，say r esearchers，got more exercise overall-mostly with their dogs-and found it worth d oing．

Answer 1

分析 本文屬于說(shuō)明文閱讀，作者主要向我們介紹了科學(xué)不能解釋寵物對(duì)我們的影響，比如有寵物的陪伴可以幫助降低血壓，提高心臟病恢復(fù)的機(jī)會(huì)，并且可以感到放松，擁有一只寵物狗也會(huì)改變你的飲食習(xí)慣，使你得到更多的鍛煉．

解答 ABCA
32．A  主旨大意題，通讀全文可知本文主要講述了寵物給它們的主人帶來(lái)的好處，故選A．
33．B 細(xì)節(jié)理解題，根據(jù)第一段but many studies have shown that the company of pets can help lower blood pressure （血壓） and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．但是許多研究表明寵物的陪伴能幫助降低血壓，提高心臟病恢復(fù)的機(jī)會(huì)，減少孤獨(dú)感而且會(huì)傳播多方面的勇氣．可知本題答案為B選項(xiàng)．
34．C  細(xì)節(jié)理解題，根據(jù)第二段It seems people feel more relaxed （放松）around pets，says Allen，who thinks it may be because pets don't judge．認(rèn)為寵物不會(huì)判斷的艾倫說(shuō)似乎人們與寵物在一起時(shí)會(huì)更放松．可知面對(duì)壓力時(shí)做的更好的原因是因?yàn)樗麄儧](méi)那么緊張，故選C．
35．A  推理判斷題，根據(jù)最后一段Dog owners didn't lose any more weight than those without dogs but，say researchers，got more exercise overall-mostly with their dogs-and found it worth doing．"研究者說(shuō)養(yǎng)狗的人體重并沒(méi)有比那些不養(yǎng)狗的人減少但是得到了更多的全身鍛煉--主要是和他們的狗在一起--并且發(fā)現(xiàn)這樣做是值得的"．可知養(yǎng)狗的人們會(huì)更多的鍛煉，故選A．

點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
