In the passive subjunctive, the subjunctive forms of the copula ([§ 272]) are used as auxiliaries:—present, If I be struck; past, If I were struck; perfect, If I have been struck; pluperfect, If I had been struck. (See table, [p. 304].)

274. Progressive verb-phrases in the subjunctive may be formed by means of the copula:—present, If I be striking; past, If I were striking. The present is rare; the past is common.

Uses of the Subjunctive

Subjunctive in Wishes and Exhortations

275. The subjunctive is often used in wishes or prayers.

In the first five examples, the wish is expressed in an independent sentence. In the last two, the construction is subordinate,—the that-clause being the object of an unexpressed “I wish” ([§ 407]).

276. The subjunctive be is often omitted when it may easily be supplied.

277. Wishes are often introduced by may or would.
