La clase se centró en el presente perfecto y el presente perfecto continuo, y después amplió el trabajo con cláusulas relativas definitorias y explicativas. La tutora corrigió formas verbales, concordancia en presente simple y pronunciación mientras Celeste producía ejemplos y respondía preguntas.
Practicing present perfect
In this lesson you practiced present perfect and present perfect continuous with many example sentences and reviewed relative clauses and defining/non-defining information. The tutor corrected pronunciation, verb forms, and small grammar points while you practiced speaking and answering questions throughout.
Defining relative clauses provide essential information without commas; non-defining relative clauses add extra information and are separated by commas. Examples
The present perfect tense describes actions that happened at an unspecified time or that have relevance to the present. The present perfect continuous describes actions that began in the past and continue to the present or were recently happening. Examples

Para la etapa activa A1, semana 4, el repaso prioritario de esta clase es más pequeño que el tema principal: tercera persona en presente simple (it looks), una oración frecuente sobre ubicación (my friends live in Valencia) y la pronunciación de laboratory y sparkling. El presente perfecto y las cláusulas relativas se conservan como ampliación opcional.

Alianna J. compartió dos PDF. B1_People_Who_Changed_The_World_-_Relative_Clauses_SV_(1).pdf es una presentación de catorce páginas con explicación, práctica oral, ejercicios y tarea sobre cláusulas relativas; Celeste anotó HW 11-12, que se conserva sin reinterpretar. Complete_list_of_A2_grammar_contents.pdf es un índice visual de seis páginas —la última está en blanco— con los puntos gramaticales A2. La tutora indicó que casi todos los tiempos A2 ya se han completado y que quedan principalmente otros puntos gramaticales.
Ambos originales se conservaron con sus checksums. El primer PDF tenía texto extraíble; el segundo no tenía capa de texto, por lo que se creó una transcripción manual searchable después de revisar visualmente todas las páginas.
