Question

We are taught that business letters should be written in a formal style           in a personal one.

A．rather than

B．other than

C．better than

D．less than

Answer 1

A

本題考查副詞短語(yǔ)辨析。rather than而不是。根據(jù)句意及in a formal style與in a personal style成分一致的線索，可斷定本句是想表達(dá)“應(yīng)該……，而不應(yīng)該……”，故只有D項(xiàng)正確。句意：商務(wù)書信必須用正式文體而不是個(gè)人文體來(lái)寫。
