But the progress has been uneven, (particularly in Africa, least developed countries, landlocked developing countries, and small island developing States)。请问括号内的内容属于句子的什么成分?地点状语吗?用法是如何?谢谢。
你提问时不要随便打问号),这会让答题老师意为原句就有逗号。你可以把有疑问的部分用黑体字。particularly in Africa, least developed countries, landlocked developing countries, and small island developing states 这部分是补充性状语,对句子谓语部分作补充说明。尤其是在以下这些地方。
