最常用詞組有：
can not +V 變形有can't,could not,couldn't
may not+V 變形有might not
do not+V 變形有 don‘t,does not,doesn't,did not,didn't
其他詞組有：
have not right/responsiblity to +V 變形有 has not right/responsiblity to 無權(quán)/責任做某事不可以做某事 的英語詞組上面的就是詞組啊，呵呵呵，2個及以上單詞組合在一起表述一個意思，即為一個詞組。can not does not, might not 就是詞組了，但是他們可以省略為特定的單詞罷了。
