Thank you, Writeacher. I still have a few more paragraphs to check.

1)I think that ads can be very dangerous for children because they often show children happy for a kind of product, like a toy and so they want to be like them.
2) I think that parents should pay attention and try to explain to their children about the reality and teach them that what ads show isn’t the reality.
3) Children can fall in the trap of the fabulous world of the products that advertising shows them and they have no tools to defend themselves. The use of children in ads can have the children become victims because they can’t defend themselves….
4) Now people tend to watch adverts more and more becoming, in my opinion, mindless lumps only focused on TV and other horrible entertaining things.
5)Experts say that the latest ads don’t just sell products but they also sell “lifestyles”: this didn’t happen in the past. People can be trapped by ads into buying a lot of unnecessary products.

1. Clarify the pronouns (they, them -- make sure their antecedents are clear).

2. ... about reality ... isn't reality.

3. comma needed in the first sentence

4. comma needed after second "more"

5. comma needed

1) I agree that ads can have a significant influence on children, making them want to possess the products being advertised. This can create a desire to be like the happy children shown in the ads. To check this paragraph, I would suggest examining the use of "often" and "so" as they indicate causality. Additionally, you may want to consider whether you want to clarify the types of dangers that ads can present to children.

2) It is important for parents to play an active role in their children's media consumption and explain to them that advertisements do not always reflect reality. To check this paragraph, you may want to consider ensuring the clarity of your statement and examining the use of "try to explain" as it implies effort but not necessarily success.

3) I agree that children can easily fall into the trap of the unrealistic world presented by ads, and they may not have the necessary skills to protect themselves from the negative consequences. To check this paragraph, you may want to clarify the specific tools or skills children need to defend themselves.

4) It seems like you are expressing concern about how people are becoming more absorbed in watching ads and other forms of entertainment. To check this paragraph, consider examining the use of "mindless lumps" as it can be seen as a derogatory term, and also clarify what you mean by "horrible entertaining things".

5) Experts argue that modern ads do not just sell products, but also promote certain lifestyles. This can lead people to unnecessarily purchase a wide range of products. To check this paragraph, ensure that you have accurately conveyed the viewpoint of the experts, and consider using specific examples or evidence to support your argument.

Remember, while checking these paragraphs, it is important to also revise for grammar, punctuation, and overall coherence.
