Ⅱ. A) Read the grammar of Adverbs on pages 89 - 90 in the appendix of the textbook. Then fill in the blanks. 读课本附录 89 - 90 页关于副词的语法，填空。
频度副词表示事情发生的。常用的频度副词在频度上的差异为：＞＞＞＞＞
频度副词通常放在实义动词之。如果句子里有情态动词、助动词或系动词 be，频度副词通常放在这类动词之。

频率；always；usually；often；sometimes；hardly ever；never；前；后

根据人教版七年级下册附录中关于频度副词的语法内容，频度副词用于说明动作发生的频率。常用频度副词按频率从高到低排序为：always（总是）、usually（通常）、often（经常）、sometimes（有时）、hardly ever（几乎不）、never（从不）。在句中位置方面，频度副词一般置于实义动词之前；当句中有情态动词、助动词或系动词be时，频度副词通常放在这类动词之后。

B) Read the passage and fill in the blanks with proper adverbs in the box. Each can be used only once.从方框中选择恰当的频度副词，完成下列句子。每选项限用一次。
never seldom sometimes usually always
I like skateboarding (滑板运动) in the afternoon. I skateboard in the park near my home. The air is clean, and I can hear birds singing in the tree. I skateboard in the evening because it's hard to see the way when it's dark. I go skateboarding twice a week, at weekends, but I exercise at home instead when it rains.
My brother, Jim, doesn't like skateboarding. He goes skateboarding with me. His favourite sport is swimming.

usually; seldom; always; sometimes; never

第一空，根据“The air is clean, and I can hear birds singing in the tree.”可知在公园滑板是常去的，用“usually”；第二空，“because it's hard to see the way when it's dark”说明晚上几乎不滑板，用“seldom”；第三空，“go skateboarding twice a week”且结合“at weekends”，周末去是“always”；第四空，“when it rains”时在家锻炼，是偶尔情况，用“sometimes”；第五空，“My brother, Jim, doesn't like skateboarding”，所以从不一起去，用“never”。
