和某人熟悉可以用 be familiar with sb 吗？

Question

sb be familiar with sth.
sth be familiar to sb

这两个意思比较清楚，

请问：如果想表示，【某人和另一个人很熟悉】，能说

sb be familiar with sb 吗？

有看到说可以的， 对某人很熟悉

网上也有说是

sb be familiar with sb 表示 对某人的行为很随便。

到底哪个说法才对呢？ 谢谢

翻译几个句子来讲解吧。

1 我和他很熟悉 / 我和他不熟悉

2 我们很熟悉，因为我们都认识很多年了。 / 都认识8年了

3 我们并不熟悉，我也只是刚刚认识他而已。

英语翻译 谢谢了。

Answer 1

用于人，通常用 know sb. 或 know about sb.，很少会用 be familiar with sb

1 我和他很熟悉 / 我和他不熟悉
I know him well / I've heard about him (but I don't know him personally)

2 我们很熟悉，因为我们都认识很多年了。 / 都认识8年了
I know him very well. We've known each other for years. / We've known each other for 8 years.

3 我们并不熟悉，我也只是刚刚认识他而已。
We don't know each other well enough. We just met not long ago.

Answer 2

1. I am very familiar with him/ I am not familiar with him

2. We are very familiar, cause we know each other long time/ it has been eight years

3. We are not familiar, we just know each other.
