In this lesson, we will learn about the conjunctive particles ども and だの.
ど（も） is attached to the 已然形 of verbs to mean "even though". As for だ, use either であれど（も） or なれど（も）. This will be very old-fashioned with some exceptions.

The Particle たりとも
The conjunctive particle たりとも is closely related etymologically to であっても. It is composed of another copula verb of older-style Japanese and the particle とも. In actual practice, its usage is restricted to set phrases.
More than anything else, there was one person who took part in planning in the administration with the same sentiments as [the Prime Minister]. Furthermore, he was sitting in a high-level post, the administrative Deputy Chief Cabinet Secretary, for which no civilian had been appointed to even once in the past.
You can't even neglect it even for a moment.

The particle だの, similar to other particles such as と, や, and とか, enumerates parallel things. For the most part, its usage implies that the sentence is not completely enumerating all interrelated/parallel things, and in doing so, it usually has negative connotations. It is more correct, though, to say that rather than labeling these sentences as having a negative nuance, we can say that it is typically used for certain things that the speaker doesn't wish for and or have some sort of psychological distance.
The pattern ～だの～だの is used with two or more nouns, adjectives, or verbs, and other case particles may be found after the final instance of だの. If you can only think of one thing and wish to use ～だの, ～だのなんだの would have to be used to avoid sounding unnatural. It's also important to note that dropping any だの is ungrammatical.

Grammar Note: Notice that 教科書 and 定期券 are examples of 必要なもの. The three phrases are treated as being of the same grammatical "case/function", and given their relationship, no additional particle is needed.
Junior high students these days apparently wish for iPhones and other tablet devices.
Particle Note: The pattern ～だの～だの may change to ～だの～など under the condition that the pair of words are in the same "category". As categorization of things widely varies from person to person, there is variable opinion on grammatical acceptance of this change, which is even more apparent with more complex examples than this. However, the default pattern is always correct so long as you are using だの correctly in the first place.
