At first I didn't know what was happening to me. I started feeling sad,1and empty. My mum advised me to start 2others. I was confused (困惑的). But I decided to have a try. The next day, I went to a house.
The house was for young girls. They were left behind by their 3. When I arrived, I felt 4. I didn't know how to talk to them. So I started helping them to do their homework. And I started going there very often and 5enjoying it.
One day, I met a little girl in the house. She started asking me about my 6. She was interested while asking me questions about my family. I was really surprised because she seemed to 7 each of my answers. When I asked her if she knew her parents, she said no. This really broke my 8.
When I left that day, the girl 9 me if I could visit her more often. I smiled and said yes. I was really happy to help this 10 girl. But in fact, this little girl helped me and taught me more.
A new study found that people's lives are made shorter in North China. It showed the life expectancy (平均寿命）had been cut down by 5.5 years there. Scientists think that it is because of the heavy air pollution. It is really the truth. Our country has already done something. However, it doesn't seem to work so well.
"Air pollution is bad for people's health. The harm is much more serious than we can imagine, said Chen Yuyu of Beijing University, one scientist of this study.
There was serious smog and haze in Beijing in November 2016. The sky was gray and the air smelt strange. Heavy haze covered the city. Highways were closed and planes couldn't take off on time. People couldn't see things clearly even within 15 meters in some places. Some primary schools were closed for several days.
We should all fight against air pollution and think of good methods to solve the problem. People should be encouraged to take buses, ride bicycles or walk instead of driving cars. The factories that pollute air heavily should be closed.
"It might be expensive to improve our environment, but we must do it. Protecting our environment means protecting ourselves," Li Hongbin, another scientist, said.
Uncle Li and Uncle Wang are good friends. They live next to each other and often help each other.
But neither of them would like (use) their head. They're both poor though they work hard. Once Uncle Li went to town (take) some medicine for his wife.
In the town he heard the apples in a city were expensive (昂贵的). He told Uncle Wang about it.
They decided (carry) some apples to the city. However, a lot of apples had already been carried there when they arrived. They didn't know what (do). They felt unhappy and returned to their village. They didn't understand why they couldn't make money, but they both agreed (buy) more apples and take them to the market because they thought they didn't bring enough. How foolish they were!
