Las Clauses (Cláusulas) son grupos de palabras que tienen un significado, pero a menudo no son oraciones completas. Algunas clauses comienzan con la palabra "when" por ejemplo "when she called" o "when it bit me." Otras comienzan con "while" por ejemplo "while she was sleeping" y "while he was surfing." Cuando hablamos de cosas en el pasado, "when" es más a menudo seguido por el tiempo verbal Simple Past, mientras que "while" por lo general es seguido por Past Continuous. "While" expresa la idea de "durante ese momento." Estudia los ejemplos a continuación. Tienen un significado similar, pero hacen hincapié en diferentes partes de la oración.
