我在一篇文章上看到"HE IS HAD" 求解

(1) 之前從未見過 IS 後面可以加過去分詞的

"is" (verb to be) + 過去分詞 (past participle) = 被動式 passive voice
"He's had many different job." ('s is a contraction 縮短形 of "has" not "is")

- He's had... = He has had... (present perfect tense)
- He's working.. = He is working... (present continuous tense)
- He's told... = He is told... (passive voice / simple present)

(2) 關於USED TO

#1. used to = modal verb 過去一向; 過去曾(而現在不再)做
e.g. He used to live in London. 他過去曾住在倫敦。

#2. be used to = adjective 習慣於
e.g. She is used to hard work. 她習慣於艱苦工作。

I can't be used to do something. (correct) #2
I can't used to do something. (wrong)

I used not to do someting. (correct) #1
I did not use to do something. (correct) #1

He's told =
1. he has told (told = 過去式, 主動式)
2. he is told (told = 過去分詞, 被動式)

'S had may not equal to "is had", but "has had". That's what I see from the sentence.

I can't be used to do sth = acceptable, but seldom use this way.
I can't used to do sth = I just don't understand... it must be wrong.

I'm a newbie in this subject, hoping that I can help out.
