    (Maria and Li Lei are talking about the photos on the wall in Li Lei's home.)

Maria: Oh, Li Lei. What a nice photo? You were so cute then!

Li Lei: Yes, everybody loved me so much! In those days I was so happy.

Maria: But the family in the other photo is very big. It seems that their living conditions were not very good.

Li Lei: Yes. It's a photo of my father's family. When he was a child, most families in the country had at least

          three or four children. At that time, China was the country with the largest population in the world.

          And it was not well developed.

Mafia: Great changes have taken place in China. Of course, China has developed a lot because of our country's

          one-child policy. Now most families have only one child. I'm the only child in my family, and I'm a

          "Little Emperor".

Maria: Oh, that's too bad.

Li Lei: My granny thinks so, too. So she tells my parents to be more strict with me. But really, Li Lei, that's

          a good thing. No one likes "Little Emperors".

( )1. Li Lei thinks that China was well developed in the past.

(     )2. China has a larger population than the other countries in the world.

(     )3. China is developing more slowly than before because of China's one-child policy.

(     )4. Maria thinks it's good to be a "Little Emperor".

( )5. It's impossible that Li Lei's father was the only child in his family.
