For English references, we should also pay attention to the following two points:

① The author's name adopts the principle of "surname comes first, surname comes last", and the specific format is: surname, initials. For example, MalcolmRichardCowley should be Cowley, M.R. If there are two authors, the way of the first author remains the same. &; After that, the first letter of the second author's first name is put in front, and the last name is put behind. For example, FrankNorris and IrvingGordon should be: Norris, F.&; Gordon;

(2) Book titles and newspaper titles are italicized, such as MasteringEnglishLiterature and EnglishWeekly.

The question mark of the extended data mainly indicates the interrogative mood of the sentence, which is used after the direct question, but not for the indirect question.

Example 1: (r) Is the size broken at the dike breach?

Example 2: (r) Is it necessary to control bank irregularities?

Example 3: (w) Researchers want to know why this method is ineffective.

In Example 3, because the interrogative word why is followed by an indirect question rather than a direct question, you can't use a question mark here, but a period instead.
