Identifying grammatical structure

[glclever]

I have to answer the following questions:

1.(i) What is the difference in meaning between the following sentences?
(ii) Identify the grammatical structure underlined in each sentence

(a)When I arrived at the station the train left
(b)When I arrived at the station, the train was leaving
(c)When I arrived at the station the train had left

(a)She had her house painted
(b)She had painted her house

(a) He stopped to smoke a cigarette
(b) He stopped smoking cigarettes


(a) You must see him
(b) You must have seen him



My Answers are as follows:

1. (a) When I arrived at the station the train left
UNDERLINED GRAMMATICAL STRUCTURE = SIMPLE PAST TENSE
(b) When I arrived at the station, the train was leaving
UNDERLINED GRAMMATICAL STRUCTURE = PAST PROGRESSIVE TENSE
(c) When I arrived at the station the train had left
UNDERLINED GRAMMATICAL STRUCTURE = PAST PERFECT TENSE

DIFFERENCE IN MEANING = USES OF DIFFERENT PAST TENSES INDICATE THE TRAIN WAS AT A SLIGHTLY DIFFERENT STAGE IN LEAVING THE STATION IN EACH OF THE SENTENCES.



2. (a) She had her house painted
UNDERLINED GRAMMATICAL STRUCTURE = PAST TENSE
(b) She had painted her house
UNDERLINED GRAMMATICAL STRUCTURE = PAST TENSE
DIFFERENCE IN MEANING = SPLITTING THE VERB MEANS THAT THE PAINTING WAS DONE BY DIFFERENT SUBJECTS IN EACH OF THE SENTENCES.


3. (a) He stopped to smoke a cigarette
UNDERLINED GRAMMATICAL STRUCTURE = VERB
(b) He stopped smoking cigarettes
UNDERLINED GRAMMATICAL STRUCTURE = NOUN

DIFFERENCE IN MEANING = CHANGING THE VERB INTO A NOUN BY ADDING .ING MAKES THE SENTENCE CHANGE FROM EXPLAINING SOMETHING WHICH HE CURRENTLY DOES DO INTO SOMETHING WHICH HE NO LONGER DOES.

4. (a) You must see him
UNDERLINED GRAMMATICAL STRUCTURE = MUST IS A MODAL VERB THAT HELPS TO EMPHASISE THAT THE SPEAKER WANTS THE SUBJECT TO SEE HIM
(b) You must have seen him
UNDERLINED GRAMMATICAL STRUCTURE = MODAL + ACTION VERB

DIFFERENCE IN MEANING = (A) MEANS TO DO IN THE FUTURE AND (B) MEANS IN THE PAST

Please can you tell me if my answers are correct?

Thanks

Your answers seem perfectly alright. Good Job

I think you could add more to the first to tell us what stage the train would be at in the three forms and who did the painting in the second. And you might want to check 2a- you're right about the tense, but have not mentioned the structure being used- have + noun phrase + past participle. The structure can be used in different tenses and forms- I'm having the house painted next week, etc.
