In this case dip means taking a swim. However, the sentence would normally be written 'we took a dip in the river before breakfast'. If it was a decrease in water level it would say 'the river dipped before breakfast'. However, it would be uncommon to use dip in this way, unless specifically to play on the two meanings of the word. Hope this helps

Try and do something every day - read an online newspaper or magazine, listen to the radio or podcasts, write emails or blogs in English, talk to people in English. Five minutes every day is better than 1 hour once a week. 10 minutes every day is even better! Make sure you practice reading, writing, speaking, listening. Try to practice new vocabulary as soon as you learn it.

Yes, you can use two verbs in this way. However, I would probably use 'bring together' rather than associate, because you can't associate other people. People associate with each other. In other words, it is an active verb, not used in this passive way. I would also probably use 'in order to' for the second part, in order to clearly show that it is a sequence. That is, you are only doing the first action in order to acheive the second one. It doesn't sound like a complete sentence - there should be something else at the beginning - maybe explaining who or what is doing the bringing together. So, your sentence could be '.........to bring together all the people in the industry in order to investigate the industry situation.'

'not on your life' - means definitely not! not even if your life depended on it. No way! No chance! 'I'm all ...... out' - I've done enough or too much of something! In this case, shopping. So I'm exhausted, or I have no money left, or I can't carry any more bags, or I have been to all the shops! (or a combination of these ideas)

This means that his way of speaking, partly the content but also the tone, the choice of words, his way of espressing himself, makes him sound older than he is. I assume from this sentence that a younger person is talking about valuing life in a way that implies they don't have many more years to look forward to, that is, using a way of speaking that is more common with older people.

act out = to perform / demonstrate how to do something (he acted out the movements necessary to complete the task so that we could copy him) act out = to behave badly, usually as a result of anger or other negative emotion. (the kids were acting out in class today) You can also use 'act up' in the same way. act on = to take action as a result of something. (she acted on his suggestion, and applied for a new job. The army were acting on orders from the government)
