根据短文内容,简要回答下列问题。

China has the world’s largest population and there are also a lot of poor people. So the government uses a different way from the UN to tell how many of her people live in poverty(贫困). Chinese living on less than 637 yuan a year are in terrible poverty. Those who live on less than 882 yuan are in the low income (低收入) group.

In 1978, 250 million Chinese lived in extreme(极端) poverty. Today, 29 million, or 3 percent of the population, are still very poor. Most are farmers from Central (中部的)  and Western China.

Since 1980, the government has spent more than 102 billion yuan building roads and giving clean water to poor people.

To make life better for them, the government also plans to put 12 billion yuan into helping the poor this year.

The government also plans to help farmers find jobs in cities by teaching them new skills (技能).

They hope that one day no one will have to worry about where to work or where the next meal will come from.

小题1:Which country has the largest population in the world?

小题2:How many Chinese lived in extreme poverty in 1978?

小题3:How much has the government spent in building roads and giving clean water to poor people?

小题4:How does the government plan to help farmers find jobs in cities?
