akdown消除，thefirst后常用不定式作定语。故填down。.答案：sincerity解析：考查名词。句意：我们用真诚和忠诚创造了一种和谐的气氛。根据句意及空后andfaithfulness提示可知此处用名词。.答案：says解析：考查时态和主谓一致。句意:瓶子上贴着一个标签，上面写着“一次吃三片;一天三次、which引导定语从句，先行词为alabel,所以从句谓语用第三人称单数形式，根据is可知此处应使用一般现在时，故填sayso.答案：cheerful解析：考查形容词。句意：喝水真的能让你保持愉快。分析句子可知此处包含”keepsb.+a力”结构，故用形容词作补语。.答案：explorers解析：考查词性转换。句意:当西班牙探险家在15世纪晚期到达中美洲时，人们已经会用香料制作热的和冷的巧克力饮料了。根据句意可知此处用名词，且其前没有限定词，所以用复数。二、七选五答案：①-⑤DBFEC解析：解析：本文是一篇说明文,介绍了作者对人类城市与野生动物关系的思考。①由空前的Citiesarebuiltforhumans.和空后举的例子可知，城市并不总是为野生动物提供合适的住所。故选D。②此处设空在段首,考虑到段首句的作用，往往为主题句;由后面细节句…engineersaddedsmallgapsrunningalongthelengthofitsbottom…可知，我们人类的行为有时是可以帮助到其他物种的。故选Bo③根据空后句的时间标志词可以判断设空处所填句子与后文内容存在时间节点的对照关系。故选FoAtfirst与后面的Now形成对比。④空前句Inmanyways,theparkistheoppositeofazoo.中的opposite与E项中的Insteadof形成意义上的呼应。故选E。⑤上文谈及人类与野生动物共享城市空间的好处，空后句所涉及内容与空前句意思相反，结合空后句的标志词too可知这里在说与空前内容相反的内容。故选C。三、阅读理解答案：1-4.ABCB解析：本文是一篇说明文。由于人类活动的影响导致全球变暖，气候变化影响到了海洋生物的生存，又反作用于人类的生计，人类必须采取措施应对此问题。.主旨大意题。通过第一段我们知道了海洋面临的现状:在过去的50年里，海洋中零氧水域的水量增加了四倍多。低氧场所自1950年以来增加了十多倍。通过这些现状，科学家预计，随着地球变暖，即使在这些区域之外,氧气也会继续下降。由此可知海洋正在失去氧气。故
