在引言从句之后使用逗号。

Example: She said, “I was in London last year.”

如果直接引语位于句首，把逗号放到最后的引号前面。 （不要在这里使用句号。）

Example: “I was in London last year,” she said.

如果直接引语以问号或感叹号结束，请勿在直接引语后使用逗号。

Example:
 “Were you in London last year?” he asked. (but: He asked, “Were you in London last year?”)
 “Great!” she replied. (but: She replied, “Great!”)
