择友与友谊

　　1. Birds of a feather flock together. 物以类聚，人以群分。

　　2. A man is known by his friends. 什么人交什么朋友。

　　3. Keep good men company and you shall be of the number. 近朱者赤，近墨者黑。

　　4. A friend in need is a friend indeed. 患难见真情。

　　5. A friend is easier lost than found. 得朋友难，失朋友易。

　　6. A faithful friend is hard to find. 知音难觅。

　　7. A friend is never known till a man has need. 需要之时方知友。

　　8. Misfortune tests the sincerity of friends. 患难见真情。
