Hi Helena, I hope this helps. I correct it as I understand it, but without asking some questions, sometimes we have different perspectives than the student, so the language can be different.

exercise 2

Sleeping is for healthy and success life one of most important things for a healthy and successful life. If you go to sleep irregularly, you probably don't won`t have enough time for tasks during the day. Therefore you should try to go to bed and wake up at the same time every day and you will see the difference soon.
People who never say no to helping other people usually don't have enough time for themselves. If someone asks you for a favor, you should think about whether you have enough time for that and if it is unnecessary. I don't say that you should be selfish but your personal goals and plans should be your priority.

Because you said PROBABLY in the if sentence, I would use the 1st conditional.

Hi there, Thank you is standard, could be said to anyone, young old, familiar, unfamiliar. It also expresses greater gratitude than a simple thanks. Thanks is more informal, too. So if someone offers you a homemade cookie, you can say simply thanks, especially if you know this person. Or it`s a stranger but the same age, let`s say. But if someone donates their kidney to you (just making a point) you can`t just say Thanks.

Hi there, 1. My favorite pets are a dog and a cat. 2. Grammatically correct, but I would probably say He is going to see a performance in the Beijing Opera. 3. We must let people live a happy life in this house. - again, grammatically good without IN but could be rephrased depending on the context.

Hi Jack, 1. This means if you have that experience in your life. If you have ever gone to a restaurant any time before now in your life. That`s what the present perfect expresses here. 2. This is about habit. Is it your habit to go to restaurants? That said, I think the sentences would be better like this 1. Have you ever been to A restaurant? (any restaurant) OR Have you ever been to THAT restaurant (a particular restaurant) 2. Do you ever go to A restaurant?

Dear Sema,

Just a few corrections and expressions to make it sound more natural in English.

Yesterday

I did a lot of things yesterday. I woke up at 7 a.m. then I went to my work. I work as a teacher for children.
I chose this field because I love so much treating dealing with children (handling children) so much. I teach them Arabic and math, I love alot playing with them a lot. When I came back I didn't take any rest, I started cooking. I'm a good cooker. Then I went to club (gym?) to practice running. I met my friend there, she gave me a present and two books and we spoke during running. Then I bought things from the supermarket and returned to my home. (went back home- it is more informal)

Hi there, The second question is wrong. Look into subject/object questions. It`s the kind of sentence when we say " What made that noise?" (when you hear some strange noise) There is no helping verb in the sentence, just the main verb, when we ask about the subject of the sentence. The answer could be " the cat made that noise" The cat is the subject of the sentence.

Hi there, You can say I prefer Coke to Pepsi. = I like Coke more than Pepsi. Or to answer a question: What do you like better Coke or Pepsi? I prefer Coke.
