问题 A 50-ft wave travels at speeds______20 m. p. h. , and anyone who’ s too slow at the approach risks being smashed.

选项 A、in excess of
B、in the reach of
C、in exchange for
D、in relation to

答案A

解析 这句话的意思为,“50英尺的海浪以——每小时20米的速度前进,人如果太慢的话就有被撞的危险。”根据句意,不可能用in exchange for(交换)和in relation to(关于,涉及)。in the reach of表示“在可及的范围之内”,而原句显然不是指地域的概念,只能用in excess of,表示“超过”。如:He was spending in excess of his income.(他的支出超出了收入。)The money they took with them was considerably in excess of what theyneeded.(他们带的钱大大超过所需要的数目。)
