___(disappear)sinceahundredyearsagoasaresultofbeingdrained(排水)foreitherfarmland10．____________otherindustries．Thatmeanslessspac

eforanimalstofeedandraisetheiryoung．1．werefound解析：考查一般过去时的被动语态。设空处所在句意为“一百多年前，从美国的西南部到南美的阿根廷都能发现美洲豹的踪影”，故find与jaguars之间是被动关系，应用被动语态，

且由Ahundredyearsago可知，此处应用一般过去时，故填werefound。2．natural解析：考查形容词作定语的用法。设空处作定语修饰habitat，表示“自然的”，故填形容词natural。3．mostly解析：考查副词。设空处作状语修饰谓语动词live，表示

“主要地”，故填副词mostly。4．to解析：考查介词。accordingto意为“按照，根据„„所说”。5．is解析：考查主谓一致。设空处所在句描述现在的情况，应用一般现在时，因为主语是habitatloss，故填is。

6．scientists解析：考查名词的数。设空处作主语，表示“科学家”，因为scientist是可数名词，由Most及谓语动词agree可知，此处应填scientists。7．an解析：考查不定冠词。设空处所在句意为“树木在气候变化方面起着重要作用”，又因i

mportant的发音以元音音素开头，故填an。playanimportantrolein．．．意为“在„„方面起重要作用”。8．trapped解析：考查过去分词作表语的用法。设空处所在句意为“森林面积的减少意味着越来越多的温室气体停留在大气层

里”，trap与greenhousegases之间是被动关系，故填过去分词trapped。9．havedisappeared解析：考查现在完成时。由sinceahundredyearsago可知，此处应用现在完成时，因为主语是halfoftheworld’swetlands，故填haved

isappeared。10．or解析：考查连词。either．．．or．．．意为“或者„„或者„„”。
