“Tom, Tom, ________ up. It's 7 o' clock. It's time to go to school.”

I opened my ________ and knew I was still in bed. I ran to my desk and my computer was ________ there. I knew it was a dream and said to ________ “From now on, I'll have a ________ life away from the computer.”

Thank you for your last letter. I enjoyed reading it very much. Thank you for telling me about your best friend. In this letter I will tell you about mine. Her name is Linda. Linda has long and dark brown hair and green eyes. She is the same age as me, but a little taller. She is always happy and cheerful.

We sit together in class, and help each other with our schoolwork. We always go home together after school and play computer games for an hour. Linda thinks very quickly and usually wins. Linda is learning to play the piano. I'm learning to play the flute（笛子）.We practice together every day. We play easy duets（二重奏）for piano and flute. They are fun.

Sometimes Linda stays overnight at my flat, or I stay overnight at her house. We always have a lovely time. How about you?

Yours,

Millie

China will carry out its seventh population census(人口普查) from November 1. Census workers will go to every home to check who lives here.     51    

China holds a census every 10 years. The first one was in 1963.     52     But in 2010, the number was 1.37 billion(十亿).

Why does our country carry out a population census?

    53     China has the biggest population in the world, and it is still growing. The government(政府) could use the information from the census to help people live better lives. For example, if the population census shows that there are a lot of kids in your area, the government will know that they have to build more schools there.

Second, from the population census, scientists can learn more about population growth(增长). In some years, the population grows faster than in others.     54     Scientists can use the information to look for reasons behind the growth.

Third, the census will help to find the number of foreigners living in China. It can also find out how many Chinese have moved to other countries.

    55     In the US, census workers first mail out a questionnaire(调查问卷) to every house. If they don’t get it back, they call the house by phone. In Australia, people can fill in a questionnaire online.
