be动词到底能加副词吗?

it is currently available. it is compeletly devasted . it is absolutely wrong 这三个句子中的副词是修饰后面的形容词available, devasted , wrong的.并不是修饰be动词.上面这三个句子是正确的.副词的常见用法有：主语+be+副词+形容词it is currently available
主语+动词+副词 It rains heavily.
主语+副词+动词 I hardly can believe you.
副词, 主语+谓语+宾语 Obviously, you are right.
放在句子后面I will finish my homework quickly.
