I attended a lecture on economics today.

The Yangtze River is the longest river in China.

The music was within audible range.

I submitted the report to the manager.

He was in ecstasy from the joy of success.

I saw a goose in the park.

I asked the station master about the train schedule.

He sat in front of the computer for a long time.
