Common mistakes that intermediate-upper intermiediate students make (B1)
The Adjectives have no plural form in English. In Spanish you way “los libros rojos” but in English you must say “The red books”.
Some verbs are followed by the gerund or infinitive. For example: “I like dance” is incorrect because like is commonly followed by the gerund, so you should say “I like dancing” or “I hate dancing”.
Some students forget to write “to”. Want is followed by the infinitive. For example: I want to go to the beach. And NOT: I want go to the beach.
Subject/ Verbs/ Object – Do not forget to write the subject and do not repeat it. For example: The house is green. In Spanish sometimes you do not write the subject for example: “Me gusta la película porque habla de amor”, but in English you need to say: “I like the movie because it talks about love”. Not: “I like the movie because talks about love”.
Its vs It’s (different words) Its is a possessive pronoun. For example: The boy has a pet. His pet is a dog. It’s = It is. For example: It’s rainy today.
Children is a plural noun. For example: The children are playing. NOT: The childrens are playing. Use a/ an + singular nouns. For example: A book (“un libro”). NOT: a books (un libros).Singular and plural (countable and uncountable) example: children, a sports
These vs this. These = plural. For example: These books. This = singular. For example: This book.
Thing vs think. Think is a verb, the past is thought. Thing is a noun. Think = “pensar”. Thing = “cosa”.
