da；a解析：考查冠词。第一个空泛指“一场火灾”；而第二个空是特指上文已提及的火灾，所以答案为b项。句意：昨夜我的邻居家里发生了一场火灾，消防员花了大概一个小时才将它扑灭。答案：b2ashley，_such cases，is sure instantly to come up with a brilliant idea.aexperiencing bhaving experiencedcto experience dexperienced解析：考查非谓语动词作状语的用法。由后半句的“一定能想出一个出色的办法”可以看出，那个年轻人一定经历过类似的情况。所以要用分词的完成式，强调动作的结果。答案：b3i wonder _ of you is _ such an accident.awho；to be blamed on bwhom；blaming tocwhich；to blame for dwho；to be blamed for解析：表示给定范围内的人，问“谁”时用which；be to blame for“因而受到责备”。答案：c4he is said _ by a famous university，for which he has worked hard for three years.abeing admitted bto being admittedcto be admitted dto have been admitted解析：考查sb.is said to do结构。动词admit发生在主句的谓语动词之前，因此d项符合。答案：d5im sorry to have interrupted you.please go on.then，where was i?oh.you _ you didnt adapt to the way that the people lived there.awere saying bhad saidcsaid dhad been saying解析：考查时态。对方问的是刚才被打断的时刻谈的是什么话题，所以说话人回答的是刚才对方正在说的内容，因此用过去进行时。答案：a6i think he must have a dictionary you need，_ he?amustnt bdoesntcdont dhasnt解析：考查反意疑问句的构成。情态动词表示推测时，其后的反义疑问句没有表示过去的时间状语时，由动词决定，动词have是行为动词，由主语he可知用doesnt。答案：b7one of the requirements for a fire is that the material _ to its burning temperature.ais heated bwill be heatedcbe heated dcould be heated解析：考查虚拟语气。that引导的从句作requirements的表语从句，因此要用虚拟语气“(should)动词原形”，should可以省略。答案：c8well continue to learn by ourselves when we have graduated.we must _ learn how to study in the university now.ain all bafter allcabove all dat all解析：考查介词短语辨析。above all表示“首先，最重要地”。句意：我们毕业后将继续自学，但最重要地是现在要学会在大学里如何学习。答案：c9marys screaming made the girls _ around her frightened.aseated bseatingcto seat dseat解析：考查非谓语动词。句意：mary的尖叫声把坐在她周围的女孩们吓坏了。由句意可知“_around her”做girls的定语，动词seat常用的结构有be seated和seat oneself表示“就坐”，这里seated表示坐着的状态，相当于sitting，seat表示“坐着”时，如果用seating作补语、定语或状语，其后面需要跟宾语。答案：a10the boy who had been seriously injured in the mudrock flow was so well looked after in the hospital that he could _ get out of bed without help.anearly bmerelycbarely dhardly解析：考查副词辨析。句意：在泥石流中受伤的那个男孩在医院里得到了如此好的照顾以至于他几乎不需要别人帮助就能下床了。nearly“几乎”；can hardly和can barely都表示“几乎不能”，表示否定，不合题意；merely“仅仅”。答案：a11is there a bookshop around _ i can buy an englishchinese dictionary?awhich bwherecthat dwhat解析：where引导的是定语从句，修饰先行词bookshop，around在此处是副词“这附近”。答案：b12in no country _ britain，as is often said，_ experience four seasons in a day.arather than；can onebrather than；one cancother than；one candother than；can one解析：other than“除了”；rather than“而不是”；in no country位于句首，句子要部分倒装。句意：据说除了英国外，再也没有哪个国家能在同一天内体验到四季。答案：d13_ we have some sympathy for them，we dont think they are right to do so.aif bwhilecwhen das解析：考查连词的用法。句意：虽然我们有些同情他们，可是我们认为他们这么做不对。此处的while表示“虽然，尽管”，用来引导让步状语从句。答案：b14will you go to qingdao for a holiday?if your brother does，_.aso do i bso i docso will i dso am i解析：考查so引导的倒装句。if从句中用的一般现在时，主句中要用一般将来时，因此选c项。答语句意：如果你兄弟去，我就去。答案：c15thanks for your mp5.ill return it to you as soon as possible._.ive got a new one from my uncle.anothing serious bno hurrycwith pleasure dnothing much解析：考查交际用语。由“ive got a new one from my uncle.”一句可知，前一句应该用“no hurry.”。答语句意：不用着急。我从我叔叔那里拿来了一个新的。答案：b二、阅读理解1from the first paragraph，we can know_.aplants can only move a littlebplants do not need to feedcplants can not get minerals by themselvesdplants are the most developed organisms on earth解析：细节理解题。根据第一段they do not have a mouth or a digestive system and they do not move much to find or catch their food可知，植物不能移动很多去寻找或是捕食它们的食物，即可以移动一点点。答案：a2what does the second paragraph mainly talk about?awhat organic matter is.bwater is very important to a plant.cwhy minerals exist in a plant.dwhat a plant is made of.解析：段落大意题。第二段主要介绍了植物的三种成分：水、矿物质和有机物。答案：d3what does the underlined word“wilt”in paragraph 3 probably mean?abe cut off. bbe broken.cdry out. dturn red.解析：词义猜测题。根据上文it is true that plants need a lot of water to stay healthy and plants are mostly made of water可知，植物需要很多的水来保持健康，植物主要由水组成。再根据if we do not water plants they will.and eventually they will die可知，没有水，植物将会枯萎，最终死亡。由此可推知，画线词含义为“枯萎，干枯”。答案：cbanacondathis south american creature appears in films or your nightmares.they have weighed over 230

that dogs have died by contacting a tissue on which a golden poison frog had wandered！while the golden poison frog might be the most harmful south american animal，it also has poison frog neighborhood friends.in intense colors，they absolutely look appealing to capture and touch，but humans should stay far away from them.piranhadespite the fact that only a small number of many kinds of piranhas are thought to be dangerous to humans，the redbellied piranha is one of those.the myths show that a large group of piranhas can absolutely eat a herd of large animals crossing the river，leaving only bones.piranhas live in the freshwater streams of south america，and they can smell blood from far away and launch attacks swiftly.it is reported that they are only dangerous to human beings if the water of the river becomes less or they are short of food.take good care，though，in entering the waters.the piranha in reality is one of the most dangerous animals.本文介绍了南美洲的三种最危险的动物。5what is special
