狐狸姐姐说的太有道理了.
My brother got in to Washington Uninversity in St.Louis in 1983. He did not even have $50 to pay the fee of TOEFL test. There are only 40 bucks in his pocket when he arrived in US. My parents and whole family had zero investment on him. However he helps every famaily member and improves the quality of everyone's life hugely and significantly. He has been a senior manageement officer at a wall street finanacial firm for over 15 years.
