1. Raise

Raise needs a direct object - if you raise something you move it up. It has both literal and non-literal meanings and it is a regular verb, so it's past and past participle forms are raised.

动词 “raise” 后需要加直接宾语，如：“raise something”，意思是 “把某物举起、抬起、提起”。“Raise” 既可以指 “抬起具体的事物”，也可以表示 “增加，提高某事物”。“Raise” 是规则动词，所以过去式和过去分词均为 “raised”。

I raise my eyebrows when I'm surprised.

The government plan to raise taxes.

He raised his voice at me in anger, but I forgave him.

2. Rise

Rise does not take a direct object - things rise or go up by themselves. Rise is an irregular verb so the past form is rose and the past participle is risen.

动词 “rise” 后不需要加直接宾语，如： “something rises”，意思是 “某物自己升起、升高”。“Rise” 是不规则动词，它的过去时为 “rose”，过去分词为 “risen”。

The bird rose into the air and flew away.
