Una forma de comparar dos cosas es diciendo en qué se parecen con "AS... AS", o en qué se diferencian "(NOT) AS... AS".
- "My trainers are as trendy as yours" (My trainers are trendy / Your trainers are trendy)
- "Cristiano is not as good as Messi" (Messi is better than Cristiano)
Si queremos enfatizar la cualidad expresada por un adjetivo añadiéndole una frase, utilizaremos "so ... that ..."
- "Gwyneth Paltrow is so beautiful that everybody looks at her"
- "Gwyneth Paltrow is such a beutiful actress that everybody looks at her".
Normalmente so... that y such ... that nos sirven para unir una causa y su consecuencia.
- "Gwyneth's performance was so good in Shakespeare in Love that she won an Oscar"
- "Gwyneth did such a good performance in Shakespeare in Love that she won an Oscar in 1999".
