  • Use Rhythm and the verified unit grammar accurately in context.

Bài giảng

Pronunciation: Rhythm

PROTECT the FOREST; KEEP the RIVER CLEAN. Content words form the main beats; short function words fit between them. Read: We can protect the forest if we work together. Do not delete meaningful syllables to force equal timing. A clear, intelligible rhythm matters more than mimicking one accent.

Grammar and use

Reported statements often backshift after a past reporting verb: I am worried → She said she was worried. Change pronouns and time references when the reporting situation changes. Reported questions use statement word order: Where do they live? → He asked where they lived. Yes/no questions use if or whether. Do not add do/does/did inside the reported clause. A still-true fact may retain its tense when context justifies it.
