分析 本文屬于說明文閱讀,作者通過這篇文章向我們介紹了在生命的早期鍛煉可以幫助你在成年后獲得健康的生活,并通過用小白鼠實(shí)驗(yàn)證明了這個(gè)觀點(diǎn),因此作者提倡我們多進(jìn)行鍛煉,保持自己身體的健康.
解答 28.B 細(xì)節(jié)理解題,根據(jù)第四段Although the positive effects of early-life exercise lasted for only one week,it is important to note that one week in the life of a mouse is the same as about nine months for humans.雖然早期的正面效果只能持續(xù)一個(gè)星期,可知小老鼠的早期鍛煉能持續(xù)一個(gè)星期,故選B.
29.A 推斷判斷題.根據(jù)第七段:"If we could understand what sorts of exercise these might be,then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite,leading to a better chance of weight loss,"如果我們能研究出這些鍛煉形式都有哪些,或許我們可以給人們量身定做一些鍛煉建議,這樣可以帶來如期的鍛煉效果而不會(huì)增加胃口,從而達(dá)到減肥的效果,可知我們的研究還沒有到位,故選A.
30.B 詞義猜測(cè)題,根據(jù)第六段However,it is possible that certain types of exercise,done for certain periods of time or at certain light levels,might not stimulate appetite much,if at all,at least in some individuals.可知有可能一些鍛煉形式對(duì)某些個(gè)體來說不會(huì)那么刺激人的胃口,故選B.
31.D 主旨大意題,通讀全文可知本文主要向我們介紹了早期生活鍛煉的積極影響,故選D.
點(diǎn)評(píng) 考查學(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,再做出正確選擇.在做推理判斷題時(shí)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.
