其实是没什么区别的.两个都是指被困在一个空间里,但因为trap 和 lock 的不同意思,所以句子所传达的意思也会有些许不同.
1.Be trapped into 【 被困在某某地方,或中了什么圈套】
been trapped into this relatioship - 被困在这段感情里
was trapped into his lies over and over again - 一而再,再而三的中了他的谎言圈套
2.Be locked into 【 被困,被锁住】
been locked into the room -被关在房间里
been locked into the binding agreement - 被锁在誓言中
