语篇解读:
本文是说明文。
文章介绍了美国国家海洋和大气管理局发布的一项新研究发现——北极气候变暖的问题及其影响。
1.Released release与theannualArcticReportCard之间是被动关系,此处表示被动和完成,故填released。
2.warmer 由thanever“比以往任何时候更……”可知本题填warmer。
3.the 形容词最高级前要加定冠词the。
4.to dueto意为“由于……”,是固定搭配。
5.reaches 因此处介绍北极的位置是客观事实,故用一般现在时。
而且and连接的是两个并列谓语,所填词与centerson并列,故填reaches。
6.fourth “the+序数词+形容词最高级”表示“第几……的”,本题填fourth,表示“第四低的”。
7.Usually 所填词修饰后面的整个句子,“通常情况下,这些海洋哺乳动物移动到漂浮的冰块上来配偶和繁殖。
”修饰句子的词常用副词,故填Usually。
8.and 文中“mate”和“givebirth”是两个并列的动作,故填and。
9.beaches beach是可数名词,故要么其前有限定词,要么用其复数形式,所以本题填beaches。
10.behavior 因所填词在句中作表语,而且被形容词new修饰,形容词又常修饰名词,故填behavior。
