Hi "Who am I", ILya has perfectly explained the difference between the two sentences. Now here is the difference between "a/an" and "the". A and AN are indefinite articles. "Indefinite" means "not specific". Use A(AN) when you are talking about a thing in general. "I have a phone." "Do you have a phone." "The" is a definite article. "Definite" means "specific". We use "the" when talking about something which is already known to the listener or which has been previously mentioned, introduced, or discussed. For example: "I have a phone. The phone is black." "Do you know where are the car keys?" NOTE: "The" is also used for singular and plural nouns. For example: "I saw the kangaroo at the zoo." "I saw the kangaroos at the zoo." Hope this helps. Alex

Hi Ariel, "I am Chinese" (I'm Chinese) is correct. When "a" is in front of the nationality, it becomes an adjective which then needs to be followed by a noun. For example: a Chinese man - a Chinese woman - a Chinese car - a Chinese person. For example in this dialogue: Ariel: Hi Alex. Where are you from? Alex: Hi Ariel, I'm from Switzerland. And you? Ariel: I'm from China. What is your nationality, Alex? Alex: I'm Swiss. I'm a Swiss man. And you? Ariel: I'm Chinese. I'm a Chinese woman. I hope this was clear and easy for you to understand. Alex

Hi Ethan, All three sentences are correct. Even though the 3rd sentence sounds strange, it it correct. Warm regards, Alex

Hi Anna, The difference between "I like watching TV" and "I like to watch TV" is this: "to like" is a verb that can be followed by a verb in the infinitive form and by a gerund. When it is followed by a gerund, it expresses a liking or a disliking. For example: "I like cooking" or "I like getting up early." When it is followed by a verb in the infinitive form, it expresses a habitual preference, something that we do not necessarily like or enjoy but consider as useful to do. For example: "I like to cook" or "I like to read a book before going to bed." I hope my explanation was clear and easy enough for you to understand it clearly :-) Feel free to get in touch with me if you need more help with improving your mastery of English. I would be glad to help you. See you soon, Alex

привет Yuliya, "Do you like cooking?" is a correct question in English. However, "Are you like cooking?" is not correct and does not mean anything in English. "to like" is a verb that can be followed by a verb in the infinitive form and by a gerund. When it is followed by a gerund, it expresses a liking or a disliking. For example: "I like cooking" or "I like getting up early." When it is followed by a verb in the infinitive form, it expresses a habitual preference, something that we do not necessarily like or enjoy but consider as useful to do. For example: "I like to cook" or "I like to read a book before going to bed." I hope my explanation was clear and easy enough for you to understand it clearly :-) Feel free to get in touch with me if you need more help with improving your mastery of English.

Buongiorno Martina, In the figurative sense, "to focus on" and "to concentrate on" both have the same meaning. In these examples: "Please leave me alone; I need to focus on this project." - "Please leave me alone; I need to concentrate on this project." "Lasciami stare per favore. Devo concentrarmi su questo progetto." It is only in this context that both of them have the same meaning. In other contexts, they do not have the same meaning. Because English is a very contextual language, the meanings of most words and verbs will change depending on the context that they are used in. I think that this dictionary will help you to better understand the difference between "to focus" and "to concentrate": http://www.wordreference.com/enit/focus http://www.wordreference.com/enit/concentrate I studied Italian at school but I have forgotten 98% of it but don't hesitate to get in touch with me if you need more help with improving your English. :-) A presto Alex
