2. Lacking in money, he couldn't spend his holiday in Shanghai this summer.
Q：这两句是否都对？

句２类似结构的关键是 be lacking in + quality
Lacking in courage, he would never leave home.
Totally lacking in charm, he could not attract the audience.
注：However, this is still not very idiomatic. I would expect:
Because he was lacking in courage, he never left home.
[注意事项]
1．There is no lack of … 总用is/was单数形式
2．For lack of 里没有the
【问题探究】 He is lack of money.
问：lack 是名词，这里似乎是不能放be动词后的吧？
答：That’s water.名词有时也能用在be动词后。这似乎有些题外了。当然本题句是错误的，
下面的都对：
1. He lacks money [lacks = verb]
2. He has a lack of money [lack = noun]
3.He is lacking in money [lacking = adjective]
"He is lack of money." （X）
"He suffers from a lack of money/confidence /personality/etc." ("Lack" = noun.) （V） "I can't meet you today for lack of time." ("Lack" = noun.) （V）
"Lacking" 可以是adjective, 常用于be lacking in sth. 结构。且那sth.应该是抽象的事物，故上面的句3也错误了。
题目句是错的。可以说: "He is lacking money" 或 "he lacks money". 如果说 "He is..." (如 "He is a teacher") 那么就是在描述他什么, 也就是他自己不能是(a lack) < he cannot himself be 'a lack'>
有时人们把lack用与这样的句子，如 "He lacks common sense/initiative". 'To lack' 是个很华丽的古英语动词, 但现在人们也许更可能用 "He has no...".
