orbeginners(計(jì)時(shí)賽對(duì)初學(xué)者來說是非常安全的比賽)”銜接緊密。故選D。3．B下文提示“它還需要熟練的自行車技巧，因?yàn)樗谄渌孕熊嚨母浇傩羞M(jìn)”。B項(xiàng)“Theracerequiresmorethanspeed(比賽需要的不僅僅是速度)”引出下文。下文中的also將上下句緊密聯(lián)系在一起。故選B。4．F上文提示“公路比賽通常是最長(zhǎng)的自行車比賽”，再根據(jù)下文提示“賽道可以是一段筆直的道路，也可以是貫穿于全國(guó)的多條道路”可知，F(xiàn)項(xiàng)“Racershavetocoveranywherefrom35milestoalmost3,000miles(參賽者必須騎行從35英里到近3,000英里之間的任何距離)”切題。故選F。5．C根據(jù)空后“他們經(jīng)常加入自行車團(tuán)體，成為有執(zhí)照的車手”可知，C項(xiàng)“Ascyclistsbecomemoreexperienced(隨著自行車手越來越有經(jīng)驗(yàn))”切題。故選C。Ⅲ.完形填空【語(yǔ)篇解讀】本文主要講述了作者在失去親人后心理狀態(tài)很不好，由于受到了別人的幫助而恢復(fù)了正常。1．C根據(jù)空前的“Istumbled(跌跌撞撞地走)”和下文中的“Itriedtoholdmytears.”以及文章開頭第一句話可推知，作者聽到親人去世的噩耗時(shí)，有些不知所措，雖然是在收拾行李，卻不知道該把什么放進(jìn)手提箱里。wonder“感到疑惑，想知道”。2．B根據(jù)本句中的“formovingtoNewMexico”可推知，作者為搬家到新墨西哥州而打包(packing)。3．D根據(jù)上文可知，作者和丈夫一直在為搬家而收拾行李由此可推知，當(dāng)時(shí)作者的家里應(yīng)該是很雜亂(mess)。4．C根據(jù)語(yǔ)境可知，作者當(dāng)時(shí)的心理狀態(tài)非常不好，不能集中精力做事情。focus“集中(注意力、精力于)”，符合語(yǔ)境。5．A根據(jù)上句“Larry
