B是谓语吗？为什么不选A？aimed at warning 充当什么成分？

Answer 1

1. aim at...旨在……； aim ……at...把……对准（瞄准）……；be aimed at...旨在……
2. 句中的aimed at...是个过去分词短语作定语，相当于非限制性定语从句，即等于which is aimed at...：
The International Day against Drugs, (which is) aimed at warning people to keep away from drugs，takes place on June 26th every year.
3. B是谓语。taking place是个现在分词短语，（现在或过去）分词短语不能作谓语，只能作其他成分。分词、动名词和不定式统称为非谓语动词。

Answer 2

中间, aimed at warning people to keep away from drugs，是插入语，不影响句子成分，完整的句子是The International Day against Drugs takes place on June 26th every year.这样就能看懂了吧追问

是非谓语动词吗？那个aimed，那又是那种成分呢

追答

aimed是非谓语动词，至于它是什么成分，额，额，不能乱说，其实我也不太清楚额~~

Answer 3

楼上说的对，aimed at warning people to keep away from drugs 这个只是一个修饰成分，说The International Day against Drugs是一个什么东西，
