Natural language understanding is an important field of artificial intelligence.

Sadamichi is my best friend and always helps me.

We took a break at a roadside station during our trip.

He was anxious about starting a new business, but I encouraged him by saying, 'Even a journey of a thousand miles begins with a single step.'

He took a camera as something to take along on his trip.

He enjoyed the silence while walking on the countryside road.

He went to school through the side road.

The street was crowded, so I took a detour.

He always uses a shortcut to go to school.

Whatever happens, he will finish the job.
