Relative Clauses são orações que identificam ou qualificam os elementos que as precedem em uma frase. Elas são iniciadas por um pronome relativo. Ex.: The boy who sits next to me is very handsome. (o "boy" está sendo identificado pelo que está escrito após o pronome relativo) My best friend, who is very fat, loves Chinese food. (já sabemos quem é a pessoa -- é meu melhor amigo - a "relative clause" dá informações complementares sobre ele.) As "Relative Clauses" são identificadas em "identifying" (identificadoras e "non-identifying". Identifying Relative Clauses São "relative clauses" que identificam ou classificam o substantivo a que se referem. Estas orações dizem a que coisa ou pessoa estamos nos referindo. Ex.: Was it your car which was towed by the police? Non-Identifying Relative Clauses Estas orações apenas acrescentam informações sobre o substantivo que já foi identificado. Ex.: This is my friend Perry, who works at Contry Hospital. Frank Mcourt wrote the book 'Angela's Ashes', which won a Pulizer Prize.
