A few sentences corrections

Hi Teo,
I'm not sure I know all the answers, but since I'm interested in one of your sentences I'll try to answer:

a. The shop is closed every Sunday. / The shop is closed on Sunday. / The shop is closed on Sunday.
b. See below.
c. The ring is gold in colour (= it is golden, speaking about the colour). / The gold ring is made of gold.
d. He felt grateful to the man.
e. They had a quick breakfast.
f.  It was hard and backbreaking work / The work is hard and backbreaking because the boxes are heavy. (I'm not very sure about these. I think I don't like "work" and I would prefer "job", but since it depends on the context...)


I was interested in your sentence (b)...
He closes his stall/shop (at) about 4 pm.
... I've never known if sentences like that are ok without "at". I was once told that "around" was better in those cases. So we better wait for some expert now

(a) The shop closes (on) every Sunday / every Sundays. This sentence is better without the word 'on'.  With the word 'on', you can say:  The shop is closed on Sundays. (b) He closes his stall / shop (at) about 4 p.m.  (The word 'at' is optional.) Check a dictionary for the difference between 'shop' and 'stall'.  Basically, a 'stall' is a much smaller structure. (c) The ring is gold in colour. / The gold ring is made by gold. The ring is made of gold. (d) He felt grateful to the man. (The word 'to' is necessary.) (e) They had a quick breakfast. (The word 'a' is necessary.) (f) It was (a) hard and backbreaking work.  You cannnot use 'a' with the word 'work'.  The word 'work' is only countable when used this way, for example:  a work of art     The work is hard and backbreaking because the boxes are heavy. OK

Hi Vincent Teo

You can say these when you talk about the colour:
The colour of the ring is gold./The ring is gold in colour./The ring is golden.

If you say "The ring is gold", it is not really clear whether only the colour is gold or whether the ring consists of gold.

You can use this to talk about what material the ring consists of:
The ring is solid gold./ The ring is made of gold./ (The preposition 'by' is wrong.)
