Sentence Patterns

[dclngo]

Dear Teacher, I need help with the following ‘sentence patterns’ question:

Assume that there are five patterns:
VP1: SUB + V
VP2: SUB + V + COMP
VP3: SUB + V + DOB
VP4: SUB + V + IOB + DOB
VP5: SUB + V + DOB + COMP

Question:
1. I let the system [to] perform the task.
2. I apply the method to the platform.

Both are VP3’s sentences. True?

Many thanks,
David

Hello David

1. I let the system [to] perform the task.
2. I apply the method to the platform.

I would take #2 as a VP3, with "to the platform" as an adverbial prepositional phrase.

For #1, however, I might take "perform the task" as an object complement; but I'm not sure.

(Maybe another member will be prepared to offer a 2nd opinion.)

All the best,

MrP
