【解析】

试题分析：本文讲述了气候对人类各方面的影响

【1】has managed；考查现在完成时。现在完成时表示过去已经开始，一直延续到现在的动作或状态。根据第一句话：Man has been on the earth about one million years.（人们在地球上已经生活了大约一百多万年了）此句的句意：他们成功地活在这个星球的每一个地方，即使天气状况使生活变艰难。可知此句的时态同第一句话一样，所以要将给出的动词manage变成现在完成时，故has managed

【2】differences；考查性数一致。It is thought…是形式主语，真正的主语应该是要填的这个单词，看看这个句子的谓语是复数形式，所以主语应该也是一个复数形式，给出的单词是一个形容词，不能作主语，所以将形容词换成名词形式，故填differences

【3】adaptation；考查名词。横线前的climatic是一个形容词，通常后面都要跟一个名词，给出的adapt是一个动词，所以要将它变成名词形式，故填adaptation

【4】where；考查关系副词。根据分析，横线后的…they have had to adapt to other climates.是一个完整的句子，用来修饰横线前的areas。areas地区，地方，在定语从句中作地点状语，所以从句的引导用where，故填where

【5】vary；考查动词。seems to do似乎做某事；给出的various是一个形容词，要变成动词才符合语法规范，故填vary

【6】those；考查代词。those是“那些”的意思，一般指离说话人比较远的地方。those为了避免跟前文的people重复，同样用来指代People，故填those

【7】by；考查介词。Be explained by sth被…解释；故填by

【8】it；考查固定句型。固定句型：it is + adj for sb to do sth，尽管词句的形容词提前，但是一依旧是这个句型，所以it不能丢，故填it

【9】effect/influence；考查固定词组。Have a significant effect/influence on对……有显著的影响。横线前有have a，横线后有on，故填effect/influence

【10】changes；考查性数一致。此时的change作的是一个谓语动词，它的主语是单数第三人称的climate，所以相应的change要变为单数第三人称，故填changes
