六、1.migrations[考查名词复数。句意:自然界最为壮观的迁徙之一就是北美洲黑脉金斑蝶的迁徙。one of后接可数名词的复数形式,故空白处填migrations。.]
2.[考查冠词。句意:每年秋天,数百万只黑脉金斑蝶都会开启漫长且艰辛的旅程。不定冠词a在 此处表示泛指。]
3.to travel[考查非谓语动词。此处manage to do sth意为“设法做成某事”,不定式短语to travel作manage的宾语。]

9.awareness[考查词性转换。空白处应填名词作介词to的宾语。]
l0.greater[考查形容词比较级。此句为“the+比较级,the+比较级”结构,意为“越…,越…”,故空白处填greater。]
