I don't care so [as] long as she lets me be with her son. 只要她讓我和她兒子在一起,我不在乎。
You can take my car as [so] long as you drive carefully. 你可以用我的汽車,只要你小心點兒開。
You may use my dictionary as [so] long as you don't keep it too long. 只要使用時間不太長,你可以用我的詞典。
但是,當(dāng) as long as 用于本義表示“與……一樣長”時,與 so long as 在用法上是有區(qū)別的,即 as long as 可用于肯定句或否定句,而 so long as 只用于否定句,不用于肯定句。如:
It took three times as long as I had expected. 這件事比我預(yù)料的多花了兩倍的時間。
It didn't take as [so] long as I expected. 花的時間比我預(yù)料的短。
