一个英语从句的问题
the restaurant was awarded four stars based on its good service and food.中based on是什么从句怎么没引导词?

Answer 1

1. 此句为一个简单句,其中的based on its good service and food不是从句,而只是一个非谓语结构（即过去分词短语）做该句的原因状语.
2. 翻译：这家餐馆基于其上佳的服务和饮食质量而被授予了四星级的奖励/称号.
3. 如果要用（定语）从句的话,可以改成：
The restaurant was awarded four stars, which was based on its good service and food.
如果改成（原因）状语从句的话,可以改成：
The restaurant was awarded four stars because it had good service and food.
