I think it's "if Josh is in your xxx there's a weakest link involved", I can't make out the xxx I'm afraid, I wonder if it is Australian slang (meaning "in your team" or something like that), I don't recognise the word.

The "Weakest Link" is a British television quiz show. It starts with nine people, each has to answer general knowledge questions. At the end of every round, the contestants vote one player out of the game - they are called the "weakest link". 4.50 - I think the person just made up the name of a country that does not exist, I can't quite hear properly either!

1. " The meeting in China were delayed by three days". In this sentence, why use " by", not " for"? - "To be delayed by [a period of time]" means that the event did not start until after that period. Using "for" sounds less natural, and implies the event started but there were then delays, e.g. "the plane was delayed for three hours" implies that everybody was on the plane, sat in the airport, and it took off three hours late. 2. " As a result, he had to change the dates for his stay in China". In this sentence, why use " for', not " of"? - Either "for" or "of" would be fine here. 3. " One reason for the trip was for business". Why use " for', not"of"? - Here, "for" means "for the purpose of", so "of" would be incorrect. 4. "This tree is bending over because of the strong wind." Why use " bending over" not just " bending"? - You could say just "bending", "bending over" is more descriptive. "Bending" could describe a small or big movement, whereas "bending over" describes a big movement. 5." It is going to be windy for the new next few days." Why use " for", not "in"? - Here, "for" means "during", so "it is going to be windy for the next few days" means "it is going to be continuously windy during the next few days." "In" means "inside" or "within", so if you say "it is going to be windy in the next few days", this means "sometime during the next few days, it is going to be windy." I hope this helps, your questions are advanced - native speakers would understand you if you use these words in the wrong place!

- "such a difficult exam": "it was such a difficult exam" means "it was a very difficult exam" - "so difficult exam" is not correct, but you can say "the exam was so difficult" meaning "the exam was very difficult", or you can ask "was the exam really so difficult?", which means "was the exam as difficult as you thought it would be?"

I would say it could mean "I want to accompany you / go with you [somewhere]" , or perhaps "I want to spend time with you" - it depends on the context. Because it's slang / idiomatic, it might have particular meanings in particular places. "To roll with something" generally means "to go along with something", as in "let's roll with it" which means "let's go with it" or "let's do it (and see what happens)".

I would suggest: Dear Sir, My expertise is in computing and I recently migrated a website, including database and content files, to a new location in under 5 minutes. I have some tools which make it easy for me to transfer bulk data. I am an experienced programmer with over 12 years of experience. In addition, I have already worked on many projects similar to your project. Please let me know if you are interested. Thanks.

I would write this as: "In order to meet the demand in summer, many people demand more parks. The more facilities the local council can provide, the better for the town."

I would say that "memory" is the general concept - the ability to store information (in computers or humans!).
