Question

Half a month passed and the boy ________ all his money, so he had to turn to his friends for help.

A．ran out

B． ran out of

C．ran across

D．ran away with

Answer 1

B

本題考查動(dòng)詞短語辨義。句意：半個(gè)月后，男孩用光了所有的錢，因此不得不向朋友求助。A. run out用完,用盡。只能是物作主語，后面不能加任何東西，也沒有被動(dòng)；  B.  run out of用完,用盡。后面加“用完,用盡”的東西，也有被動(dòng)，一般是人作主語；  C. run across偶然發(fā)現(xiàn)；偶然碰見  D. run away with偷走。結(jié)合句意和短語的用法可知該選B。
