答案解析
1.in 考查介词。in excellent condition 状态良好。
2.its 考查代词。用its表示“它的”,指代“幼狮的”。
3.were discovered 考查被动语态。因幼狮是“被发现”的,用被动语态,主语remains(遗体;遗骸) 是复数,用were。(关于本题主谓一致问题,通过文章首句的are可推知用复数。)
4.published 考查非谓语。a study published in the journal Quaternary发表在《第四纪》杂志上的一项研究。句中已有谓语动词were且与所填词之间没有连词,可知填非谓语。用过去分词作后置定语,表被动。
5.generations 考查名词复数。many后用复数名词。
6.that 考查状语从句。so...that...如此……以至于……。句意:斯巴达保存得如此完好,以至于它仍然有皮毛、器官和骨骼。
7.evidence 考查词类转换。evident [ˈevɪdənt] adj. 清楚的,显然的。evidence [ˈevɪdəns] n. 证据。形容词转换为名词作宾语。
8.what 考查名词从句。what cave lions ate 洞穴狮子吃的东西。what意为“……的东西”,在及物动词learn后引导宾语从句,并在从句中作ate的宾语。
9.have increased 考查时态。in recent years 近年来。表示动作从几年前持续到现在,用现在完成时。主语为finds(发现物),是复数名词,所以用have而不用has。句意:近年来,在俄罗斯较大的西伯利亚地区也有类似的发现。
10.faster 考查比较等级。根据than可知用比较级。句意:气候变化使北极变暖的速度比世界其他地区都快。
