south during winter, spring and autumn. The plant is also able to bear（忍受） drought(干旱). In some places of China, there is not enough water. So the potato is a safer food to grow.

Now, many Chinese people treat potato more like vegetable, and eat it in the form of stir-fried (炒) potato slices and potato cooked with beef. But being a main food, potatoes can be cooked differently. Scientists have succeeded in making potato flour（粉）, noodles and other main foods similar to those made of rice or wheat.

In fact, the potato has long been a main food in many Western countries.

In the US, French fries are popular. People like sharing them with friends and families at parties. Together with ketchup(番茄酱), it is the best food to kill time.

A jacket potato(杰克薯仔) is common in the UK. It has a soft inside and a crisp skin(脆的表皮). It is very delicious with butter and cheese.

A year later, Hong's mother left home. She no longer wanted to live such a poor life and face her sick husband. So everything hard fell onto the young boy: to take care of his father and the younger sister Chenchen, and to go on to study.

Although his life was hard, Hong didn't go away from his father and sister. He took some part-time jobs to feed his family. He climbed tall trees to get birds' eggs for his sister.

To take care of Chenchen, he worked hard to rent(租) a room near his college for her, and sent her to school.
