Maybe we will______this Wednesday_______（放假）,because it is women's Day

Answer 1

正确答案及详细解释如下：

of 加上抽象名词就等于这个名词的形容词, 即 be of importance= be important .

2 Maybe we will _have_this Wednesday _off （放假）,because it is women's Day.
have a day off 就是放假的意思
希望对你有帮助．

Answer 2

importance,great后面用名词形式。
have off，这个词组表示放假。
