Idiomatic English 3 - Lesson 19

1- Some Indians were accustomed to worshipping the sun.

2- You must make children say their prayers before going to bed.

5- It seems like you've lost weight.

I think this is what you mean!

I particularly interested in the seventh sentence because one book I have says that the negative modal "had better not" is a strong prohibition and second one says it's not and it is like a warning or even a suggestion.

"You'd better not" is like a warning - it is saying there will be negative consequences for doing something. It is stronger than a suggestion. A strong prohibition would sound like "Do not", or "... is forbidden" or "... is not allowed"

1- Some Indians were sun worshipers, or worshiped the sun.accoustomed to adoring the sun.

By "accustomed" I think you mean to say "de costumbre", that is it was there cusom, culture to worship the sun. "Adore" is the wrong word here because it means to like, or love very much, as in "I adore sun bathing", while the Indians attitude towards the sun was a religious one, hence "worshiped".

2- You must make children tell say their prayers before going to bed.

As it is written it sounds like the children have to inform someone what is in their prayers, rather than saying them, presumably to God.

5- It seems like you've lost weight reduced.

Reduced is the wrong verb here, unless you were saying something like, It seems like you've reduced your waist size! :-)

6- Do you know whose this watch this is?

10- I feel sorry for people that who need to go on a diet all the time.

While "that" is often used informally in this context, since you are speaking of people, "who" would be more correct.

I'm particularly interested in the seventh sentence because one book I have says that the negative model "had better not" is a strong prohibition and second one says it's not and it is like a warning or even a suggestion.

I'd be for the second book.

I was particularly interested in the seventh sentence because one book I have says that the negative modal "had better not" is a strong prohibition and second one says it's not and it is like a warning or even a suggestion.

"You had better not" can really mean anything from a subtle suggestion to a prohibition, depending on context. Like if it's going to rain, I might tell my daughter, "You had better not leave your bike outside," but it is more of a suggestion than a prohibition. However, if she's being punished, I might tell her, "You had better not leave this room until I say you can!" In that case, it serves as a direct order with implied consequences if it is not obeyed.
