Listening to English

The month before last, I visited Paris with my family on a pleasure trip.
Before this trip, I studied English, especially listening to English,
because our trip was a personal trip, not a package tours.

I listened to pod casts and went to English lessons.
I thought if people speak slowly, I would understand what they say.

But actually it was more difficult for me to listening to English in Paris than I thought.
In my opinion, the most important reason was that English speakers weren't native.
I was used to American or British English, but not non-native English.

Last day, I participated in a conference in my company,
and there was a Chinese speaker.
Though his English was very fluently and everyone understood his English well,
it was very hard for me to listening to.

Learning English is harder than I thought.
