1．were fund 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A hundred years ag可知，此处应用一般过去时，故填were fund。
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．mstly 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mstly。
4．t 解析：考查介词。accrding t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habitat lss，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Mst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imprtant的发音以元音音素开头，故填an。play an imprtant rle in．．．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greenhuse gases之间是被动关系，故填过去分词trapped。
9．have disappeared 解析：考查现在完成时。由since a hundred years ag可知，此处应用现在完成时，因为主语是half f the wrld’s wetlands，故填have disappeared。
10．r 解析：考查连词。either．．．r．．．意为“或者……或者……”。
肯定句
be(am/is/are)＋being dne
否定句
be(am/is/are)＋nt＋being dne
一般疑问句
be(am/is/are)＋主语＋being dne
特殊疑问句
特殊疑问词＋be(am/is/are)＋主语＋being dne
