英專學生的困擾,今天終於看到權威的,希望大家根據權威來使用標點。
Use a period with abbreviations:
Dr。 Espinoza arrived from Washington, D。C。, at 6 p。m。
Notice that when the period ending the abbreviation comes at the end of a sentence, it will also suffice to end the sentence。 On the other hand, when an abbreviation ends a question or exclamation, it is appropriate to add a question mark or exclamation mark after the abbreviation-ending period。
粗略的翻譯:若以縮略詞來結束一句話,一個點同時也足以表達句子結束。若縮略詞後需要加感嘆號或者問號,可以加上這些標點。
