案：down解析：考查固定短語。句意：這兩個國家將舉行會談以消除它們之間的一些貿(mào)易壁壘。breakdown消除，thefirst后常用不定式作定語。故填down。.答案：sincerity解析：考查名詞。句意：我們用真誠和忠誠創(chuàng)造了一種和諧的氣氛。根據(jù)句意及空后andfaithfulness提示可知此處用名詞。.答案：says解析：考查時態(tài)和主謂一致。句意:瓶子上貼著一個標簽，上面寫著“一次吃三片;一天三次、which引導(dǎo)定語從句，先行詞為alabel,所以從句謂語用第三人稱單數(shù)形式，根據(jù)is可知此處應(yīng)使用一般現(xiàn)在時，故填sayso.答案：cheerful解析：考查形容詞。句意：喝水真的能讓你保持愉快。分析句子可知此處包含”keepsb.+a力”結(jié)構(gòu)，故用形容詞作補語。.答案：explorers解析：考查詞性轉(zhuǎn)換。句意:當西班牙探險家在15世紀晚期到達中美洲時，人們已經(jīng)會用香料制作熱的和冷的巧克力飲料了。根據(jù)句意可知此處用名詞，且其前沒有限定詞，所以用復(fù)數(shù)。二、七選五答案：①-⑤DBFEC解析：解析：本文是一篇說明文,介紹了作者對人類城市與野生動物關(guān)系的思考。①由空前的Citiesarebuiltforhumans.和空后舉的例子可知，城市并不總是為野生動物提供合適的住所。故選D。②此處設(shè)空在段首,考慮到段首句的作用，往往為主題句;由后面細節(jié)句…engineersaddedsmallgapsrunningalongthelengthofitsbottom…可知，我們?nèi)祟惖男袨橛袝r是可以幫助到其他物種的。故選Bo③根據(jù)空后句的時間標志詞可以判斷設(shè)空處所填句子與后文內(nèi)容存在時間節(jié)點的對照關(guān)系。故選FoAtfirst與后面的Now形成對比。④空前句Inmanyways,theparkistheoppositeofazoo.中的opposite與E項中的Insteadof形成意義上的呼應(yīng)。故選E。⑤上文談及人類與野生動物共享城市空間的好處，空后句所涉及內(nèi)容與空前句意思相反，結(jié)合空后句的標志詞too可知這里在說與空前內(nèi)容相反的內(nèi)容。故選C。三、閱讀理解答案：1-4.ABCB解析：本文是一篇說明文。由于人類活動的影響導(dǎo)致全球變暖，氣候變化影響到了海洋生物的生存，又反作用于人類的生計，人類必須采取措施應(yīng)對此問題。.主旨大意題。通過第一段我們知道了海洋面臨的現(xiàn)狀:在過去的50年里，海洋中零氧水域的水量增加了四倍多。低氧場所自1950年以來增加了十多倍。通過這些現(xiàn)狀，科學(xué)家預(yù)計，隨著地球變暖，即使在這些區(qū)域之外,氧氣也會繼續(xù)下降。由此可知海洋正在失去氧氣。故
