【解析】
本文是一篇说明文。文章介绍了地球上生命起源,主要简述了由植物到动物,由低级生命到哺乳动物进化的过程。
【1】
考查副词。句意:数百万年以后,极其微小的植物开始出现在水的表面。此处为副词修饰形容词small。extremely“极其”。故填extremely。
【2】
考查动词搭配。句意:他们快速繁殖,并使海洋充满了氧气,氧气促进了后来贝壳类生物和鱼类的发展。本题考查固定搭配:fill……with……使......充满……。故填with。
【3】
考查非限制定语从句。句意:他们快速繁殖,并使海洋充满了氧气,氧气促进了后来贝壳类生物和鱼类的发展。根据句意可知此处为非限制性定语从句修饰先行词oxygen, 且从句中缺主语,故填which。
【4】
考查一般过去式的被动语态。句意:他们之后是陆地动物。此处they代指green plants,而绿色植物应该是被陆地动物跟随,因此应该用被动语态,且此处讲述过去的事情,因此应用一般过去时的被动语态。故填were followed。
【5】
考查代词。句意:一些动物是昆虫,其他的被称为两栖动物,可以在陆地和水中生活。从处应该是指上句中land animals中的一些(除了昆虫之外)的一些动物,others表“其他的,别的”,等同于other land animals。故填Others。
【6】
考查介词。句意:其他的被称为两栖动物,可以在陆地和水中生活。此处为省略句,其完整形式为:Others were able to live on land as well as(live) in the water.,在水中用介词in。故填in。
【7】
考查一般过去时。句意:它们也产卵,并且在地球上存在超过一亿四千万年。本文主要是叙述了过去地球上生物的进化,因此此处应该用一般过去时,动词lay意为“放置,产卵,下蛋”,他它的过去式和过去分词为laid。故填laid。
【8】
考查副词。句意:然而,六千五百万年前,恐龙时代终结了。前句“:它们也产卵,并且在地球上存在超过一亿四千万年”提到了恐龙这一物种的发展,与恐龙时代的终结构成鲜明的转折,因此应用转折副词however,意为“然而”。故填However。
【9】
考查名词。句意:(恐龙的)消失使地球上哺乳动物的兴起成为可能。根据空前的定冠词the可知此处应填名词,结合句意可得出此处意为“恐龙的消失”,disappear的名词为disappearance。故填disappearance。
【10】
考查连词。句意:这些动物不同于以前的所有生命形式,因为它们生育小动物并产奶喂养它们。根据句意可知此处为因果关系,因此,应用because引导原因状语从句。故填because。
