sthereisalotofbeginnerandkidterrainforchildren.”可知“Nakiska”是最適合一家人去滑雪的地方；此處的收費標準是“Adultspay$64.5,Seniorspay$51.5,andChildrenonlypay$19.5.”，兩個成人收費129美元，兩個小孩收費39美元，合計收費168美元，故選A。5．C主旨大意題。依據(jù)全文第一段可知，全文旨在介紹幾處滑雪勝地，故選C。AAsigncanbefoundinthefrontyardofahouseintheUS.Thepeoplelivingherewanttolettheirdogplayoutsideandensureitwon’trunintothestreet.So,theyhireacompanytosetupan“invisiblefence”,anelectricwireburiedinthegroundaroundtheyard.Thedogwearsaspecialcollarandwhenitwalksneartothe“fence”,thewirewillsendoutasmallshock.Thedogquicklylearnstostayawayfromtheedgeoftheyard.Asitsaysatthebottomofthesign,thefencewillkeepyourdog“safe”(awayfromthestreet)and“athome”(containedinsidetheyard).
