【回答】

考查人稱代詞。從結構可知句子主語是不定式短語，it作形式主語填it。

ily 考查副詞。修飾整個句子應該用副詞形式，位於句首，首字母要大寫，填ily。

固定短語：be home to“……的家、故鄉、棲息地”，填to。

grown 考查被動語態。根據句意可知是被動關係，含有情態動詞的被動形式為：情態動詞+be+done，故填be grown。

e 考查定語從句。定語從句是主謂結構，缺少關係副詞，先行詞為地點名詞，故填where。

t 考查形容詞。固定短語：at least“至少”，填least。

67. are considering 考查動詞時態。根據 now 判斷用現在進行時，表示目前科學家們正在做的事情，填 are considering。

68. becoming 考查非謂語動詞。從結構判斷此處是非謂語動詞短語作定語，become 和被修飾名詞 planet 之間存在主動關係，用現在分詞，填 becoming。

69. to produce 考查非謂語動詞。固定搭配：need to do sth＂需要做某事＂，填 to produce。

70. researchers 考查名詞。根據主謂一致的原則可知此處是複數名詞，填 researchers。
