Penjelasan:

Simple past tense mengubah bentuk verb menjadi bentuk kedua. Namun apabila bentuk kalimatnya negatif (-) atau bentuk kalimatnya interogatif (?), maka bentuk verbnya tetap menjadi bentuk pertama.

Bentuk verb sendiri ada dua jenis, yakni:

• Reguler verb: Dance - danced - danced

• Irreguler verb: Speak - spoke - spoken

Sedangkan bentuk to be jika dalam keadaan lampau, maka menggunakan wasdanwere.

Examples:

Diana was at the mosque yesterday.

We were on time this morning.
