increase/increased

[alan]

"because...,the unemployment rate will increase." <--this sentence pattern is definitely correct.

how about...if we say" because...,the unemployment rate will be increased."

when we say a thing's number or quantity has increased,
is that both of the expressions "will increase" or "will be increased" are acceptable? And the meaning here doesn't involve passive or active?

i raise this question simply because i am quite confused after reading the book saying that participle form of a verb can fucntion as an adjective,

eg.I am determined to do sth.
the "determined" here doesn't convey a passive meaning,and it acts as an adjective to modify "I".

so,the question is,can we always change some verbs into a participle and use it as an adjective in a sentence ?

looking forward to seeing your reply,teachers.

Main Verb
a) the unemployment rate will increase.(Active)
b) the unemployment rate increased. (Active)

When an -ed word occurs with 'be' or 'has/had', it functions as part of that verb, as a participle:

Past Participle
b) the unemployment rate will be increased (Passive)
c) the unemployment rate has increased (Present Perfect)
d) the unemployment rate had increased (Past Perfect)

When an -ed word occurs with a form of BE (i.e., is, am, are, etc.) it functions as an adjective:

Adjective
d) I am determined. (e.g., I am happy, I am sad, I am hot, etc.)

That's pretty much the general rule.

Verb: walk, add -ed => walked
Past tense: I walked the dog. (Past Tense)
Adjective: a walked dog. (Past Participle)
Part of a verb: He has walked the dog. (Past Perfect: 'has' + past participle 'walked')

then, if that we can write "will increase" or "will be increased" to express the same idea?

will increase = will + verb
will be increased = will be + adjective
Is that right???

[alan]

moreover,+ed word occurs with a form of be,for example, "is" ,it functions as an adjective

the tax is increased. <-- does it convey a passive meaning, or the "increased" is just an adjective here??

Yes, but be increased is passive.

Active, Future: will (auxiliary) increase (main verb)
Passtive, Future: will (auxiliary) be (main verb) increased (past participle, not an adjective).

When an -ing word modifies a noun, it's called an adjective:
EX: an increased amount

When an -ing word modifies a verb, it's called a participle:
EX: unemployment will be increased

Words ending in -ing have two names:
1) gerund (Noun)
EX: Running is fun.

2) participle (Modifier)
EX: She is running. (Verb modifier = participle)
EX: He is a running man. (Noun modifier = adjective)

Gerunds always end in -ing; Participles have two different forms.
1) Present participle: a word that ends in -ing
EX: a running man (Adjective)
EX: She is talking (Participle)

2) Past participle: a word that ends in -ed or -en
EX: a wooden box
EX: a dreaded exam

Use participles to modify nouns and verbs; Use gerunds as subjects and objects.

hi teacher
what will u fill in for these blanks ?

1.As the tax rate _____, the government...
2.As the unemployment rate _____, the government...

a) increases
b) is increased

I think both of the answers are acceptable ,though,
I regard

"is increased" is more appropriate for "tax rate",as it can be changed by the goverment decision makers,the market or some other economic factors.

"increases" is more appropriate for "unemployment rate", as it cant be passively changed ,but it's only an indication to show the factual number.

what do u think ??? i really need your help as this kind of question has confused me for a long time!
