经过查询了一定的资料以后逐步分清了COMMA+VING 做MODIFIER的用法,但是在做OG15 VERBAL SC #27题时还是有所疑惑。
题目为:
Obtaining an investment-grade rating will keep the county's future borrowing costs low, protect its already-tattered image, and increase its ability to buy bond insurance.
A) Obtaining an ivestment-grade rating will keep the county's future borrowing costs low, protect.
B) To obain an investment-grade rating will keep the county's future borrowing costs low,and protect.
