modifiers are omitted, and that the other modifiers are not so necessary to
the sense. In such expressions as _I myself, we boys_, the explanatory
words are not restrictive, but they combine closely with the modified term.

ADJECTIVE CLAUSES.

Adjective clauses allow little change in position. They usually follow
closely the word modified. Often they may be contracted into adjectives or
into adjective phrases.

Selections from standard writers may be made with special reference to the
study of adjective clauses. The position, punctuation, and choice of
relatives may be noticed, and, as far as possible, the clauses may be
changed into equivalent adjectives or into phrases.

ADVERB CLAUSES.

An adverb clause may stand before the independent clause, between its
parts, or after it; as, "When it is hot, glass bends easily;" "Glass, when
it is hot, bends easily;" "Glass bends easily when it is hot." Notice the
punctuation of these examples.

Adverb clauses may be contracted in various ways. Clauses introduced by the
comparatives _as_ and _than_ are usually found in an abbreviated form; as,
"You are as old _as_ he (_is old_);" "You are older _than_ I (_am old_)."
Attention may be called to the danger of mistaking here the nominative for
the objective. We suggest making selections for the study of adverb
