forget后面什么时候加about？与一般的意思不一样吗？

forget 和forget about 的区别

一、先说forget(1) forget通常指忘记具体的东西（如名字、号码、地址等）,forget about后者通常指忘记一件事情（如开会、学习、吃饭、锁门等）.比较：I forget her name. 我把她的名字给忘了.Don’t forget about your study. 别忘了学习.They were so busy that they even forgot about their own meals. 他们忙得连饭都忘记吃.有时两者可换用,尤其是表示“不要把…放在心上”时.如：He forgot (about) her birthday. 他把她的生日忘了.Let’s forget (about) our differences. 咱们不要把彼此的分歧放在心上.二、再说forget about表示“忘记做某事”,除可用forget to do sth外,有时也可用forget about doing sth.如：She had forgotten all about posting the letter. 她把寄信的事忘得一干二净.另外,一般现在时的forget后可直接跟动名词表示忘记做过某事,但一般过去时的forgot后接动名词时,则通常会先接介词about（有时也有不用about的）.如：I forgot about doing it. 我忘记已做此事了.二、forget (about) it在口语中的用法口语中说forget (about) it有以下用法：①用于回答感谢,意为“不客气”.如：“Thank you very much for your help.”“Forget about it.”“多谢你的帮助.”“不用谢.”②用于回答道歉,意为“没关系”.如：“I’m sorry for what I said.”“Forget it! I don’t remember anyway.”“我为我所说的话道歉.”“没关系,反正我也没有记住.”③用于表示否定或拒绝,意为“不行”.如：“I’ll take the small truck.”“And leave me to drive the other one? Forget it.”“我要开那辆小卡车.”“啊,让我开另外那辆? 不行不行.”④用于表示不想提及某情况或指某情况无关紧要等.如：“How much do I owe you?”“算了吧!”

forget+ about这里的forget是不及物动词,就是不能跟宾语只能跟动词的词.
而forget是及物动词,forget sth,forget to do ,forget to do
