unit 4 ( e11) grammar (pesent perfect / simple past)

We (complete) a voluntary project for our community centre a month ago.

Since our last meeting, most of the students (become) more involved in volunteering.

Last week, the Youth Union leaders (decide) to launch a campaign to help children with learning disabilities.

Many volunteers (take) part in our programmes since the campaign was launched.

You (ever, help) students with special education needs?

Last semester my wheelchair broke down, so my best friend (carry) me on his back to school.

We (work) on this programme for five years.

Not long ago, teachers at the school for gifted students (discover) that some of their students also have learning disabilities.

Our instructors (teach) extra classes for students with learning disabilities since 2008.

We (create) a resource room for talented students with learning disabilities in 2013.
