Question

read the introduction to marias personal narrative, \teaching saturday school.\
on saturday mornings, i wol arabic to the children who attend my mosque. i wake up at eight oclock and prepare my lesson as i eat breakfast. its hard work, but the look on my students faces when they wol a new word is priceless.
fill in the blanks in order.
taught . . . . understands
taught . . . . understand
teach . . . . understand
teach . . . . understood

Explanation:

1. The first blank: The narrative uses present tense (wake, prepare) to describe a repeated Saturday routine, so the base verb "teach" (present tense for first-person) is correct, not past tense "taught".
2. The second blank: The subject "they" (plural, referring to students) requires the plural present tense verb "understand" to match the present tense context of the students' reaction when learning a new word.

Answer:

teach . . . . understand
