【简答题】
The most common punctuation marks in English are: capital letters and full stops, question marks, commas, colons and semi-colons, exclamation marks and quotation marks. In speaking, we use pauses and the pitch of the voice to make what we say clear. Punctuation plays a similar role in writing, making it easier to read. 请阅读下面的句子,注意句子中的标点符号: W e went to France last summer. W e were really surprised that it was so easy to travel on the motorways.
