语篇解读 本文是一篇应用文。这四则广告分别介绍了四项适合学生的夏季活动安排。
1.Whichactivitywillyouchooifyouwanttogocamping?
A.OUT.
B.WBP.
C.CRF.
D.POT.
答案 A
解析 细节理解题。根据题干中的gocamping可以定位到第一则广告。由该则广告中的“YouwillbeabletotakepartinanumberofactivitiesfromcanoeingtowildcampingonDartmoo r.”可知，这是户外探险活动，参与该活动可以划独木舟(canoeing)，也可以野营，因此选A项。
2.WhatwillthestudentsdoonTuesdaywithMrsWilson?
A.TraveltoLondon.
B.Seeaparadeandfireworks.
C.TourcentralParis.家规家训范本
D.VisittheWWⅠbattlefields.
答案 D
解析 细节理解题。根据题干中的MrsWilson可以定位到第二则广告。由该则广告中的“OnMondaywetraveltoLondon.AfterstayingovernightinLondon，wetravelonDay2tonorthe rnFrancetovisittheWorldWarⅠbattlefields.”可知，星期一参观者到达伦敦，第二天即星期二到法国北部参观第一次世界大战的战场，这与D项内容吻合。
3.HowlongdoesPottyaboutPotterlast?
A.Twodays.
B.Fourdays.
C.Fivedays.
D.Oneweek.
答案 A
解析 推理判断题。根据题干可以定位到最后一则广告。该广告提到参观华纳兄弟工作室、暗恋文小说推荐
去商店买野餐、在青年旅馆住一晚(stayovernight)，那么后面交代的坐船游览查韦尔河就应该是第二天的活动，由此推断这个活动的持续时间是两天。

A.Differentideasaboutthegiantpanda’scolor.
B.Howthegiantpanda’sunusualcolorformed.
C.WhatTimCarodiscoveredaboutthegiantpanda.
D.Theevolutionofcolorinthegiantpanda.
答案 A

同解释。
5.Whyarethegiantpanda’sarmsandlegsblack?
A.Tomakeitdifferentfromothermammals.
B.Toavoidbeingenbypredators.
C.Tokeepwarminthewinter.

滨江路答案 B
解析 细节理解题。根据第三段第四、五句
“helpitstayhiddenintheshadeduringsummer.Thisispartic ularlyimportantforpandababiesthatareoftenintreetopsandneedtoprotectthemlvesfro mpredators.”可
知，熊猫宝宝夏季的时候经常待在树上，它们黑色的胳膊和腿有助于将自
己隐藏在树荫里而不被捕食者发现。

A.Oversleeping.
B.Toomuchfat.
