Are 得到 and 接受 similar? I saw the previous posts about 接受 and  接收。 But couldn't find information about the difference between 接受 and 得到。 它们的对象可以是抽象的也可以是具体的？ 得到/接受的可以是好的也可以是消极的？ 
Or maybe I just need to memorize the “习惯搭配”？！
While similar, they aren't interchangeable. According to the dictionary, 

接受:
to accept; to take; to embrace; to adopt; to bow to
Examples:
他已經接受了我們的邀請。He has accepted our invitation.
山姆因為窮只得接受這份工作。Sam had to take the job because he was broke.  

得到:
to obtain; to receive; to acquire; to derive; to earn; to get; to gain
Examples:
他們從政府那裡得到一筆貸款。They obtained a loan from the government.
她應該得到此榮譽。She is worthy to receive such honor.  

接受 is passive, such as when you accept gifts or accept a situation. 得到 is for when you actively seek out or ask, and as a result, you received. 

Hope this helps!
