- V普通形 + とあれば
- いA + とあれば
- なA + とあれば
解說
A とあれば B means 'if A is the case (or if it is for A), then B.' It is often used as in 子どものためとあれば (if it's for my child) or 必要とあれば (if necessary), and B usually shows the speaker's willingness to do something difficult or unusual. It is not used for simple time conditions or natural results. It is a formal expression.
例句

If it's for his daughter, my father will drive to pick her up no matter how far it is.
必要とあれば、資料をもう一度お送りします。
If necessary, I will send you the materials again.
好きな歌手に会えるとあれば、何時間並んでもかまわない。
If it means I can meet my favorite singer, I don't mind lining up for hours.
社長の命令とあれば、断るわけにはいかない。
If it's an order from the president, I can't refuse.
注意
B is not a guess or a description of a current state. とあって gives a real reason ('because of the special situation'), while とあれば is a hypothetical condition.
小測驗

答案與解析
答案: 1 とあれば
"If my favorite cake is half price, I don't mind lining up early in the morning." といえども, とはいえ and ながらも express contrast, which does not fit here.

答案與解析
答案: 3 とあれば
"If it's for my family, I can work hard at any job, however tough." につき (due to, in notices), をよそに (ignoring) and ならいざしらず (it would be different if) do not fit.
3「とあれば」の使い方がいちばん正しい文はどれですか。
答案與解析
答案: 4 先生の頼みとあれば、喜んで引き受けます。
4 means "If it's a request from my teacher, I'll gladly take it on." 1 is a guess, 2 is a simple time condition, and 3 describes a state, so とあれば cannot be used.
