Not bad but a few things to consider. For 1) the only thing that may be a problem is the article. 'The factory' implies that the person you're talking to knows which factory it is or knows that you work at a factory. It's minor but 'a factory' would probably be better here. 2) and 4) both require question marks :) 3) has a few problems. I would never say 'turns a penny', I'd go with 'makes a living as' 'a waiter' not 'an waiter' (spelling rules) and again, the article might be a problem. 'A cafe' is probably best here. Hope this helps!

Hello!! 1) When you use the article "the", it means that the other person knows exactly what you are talking about. For example, "the flower" is that one and not any flower. Therefore, we must consider this before choosing "the" and not "a/an", or simply not using an article at all. Ex.: I earned money working at a factory. 2) and 4) These are questions. In English, we use the question mark at the end of every question when we write. 3) For this sentence you should change the verb "turns". If you want to say that he earns little money, the phrase "makes some pennies" is a right choice. The article "an" is used only when the word next to it starts with a vowel. And remember, it's ok to say "the cafe" only if the other person knows exactly what cafe you are talking about. Nice job! Good-bye!!

Hi Timur, 1 I earned money working at the factory. (There is no necessity to use a specific determiner "the" as we are referring to money in general.) 2 How much do you earn a month? (This is an interrogative sentence where you pose a question. Therefore, a question mark is required to end the sentence.) 3 Tom earns a meagre salary working as a waiter at the cafe. (The pronunciation of "waiter" does not start with a vowel sound. It is pronounced as "wey-ter". The phrase "turns a penny" describes making a small profit by trading. It does not suit the context well as Tom is an employee of the cafe.) 4 How much do you expect to earn at the firm? (This is an interrogative sentence where you pose a question. Therefore, a question mark is required to end the sentence.) Hope these help. Cheers, Lance
