6.                 The new contract forbids a strike by the transportation union.fficeffice" />

(A) forbids a strike by the transportation union

(B) forbids the transportation union from striking

(C) forbids that there be a strike by the transportation union

(D) will forbid the transportation union from striking（A）

(E) will forbid that the transportation union strikes

答案是A, B,C错在哪里呢？Longman上有forbid sb.from doing sth.的例句。ETS在OG中也只是说过forbid sb.to do sth. "would be idiomatic here",并没有说过forbid sb. from doing sth.不 idiomatic? 请指教，谢谢。
