This made them sick because there is poison (毒药) in the leaves.In the 1800s, people started to eat potatoes. Potatoes became the main food in Ireland. Then something unlucky happened. In 1845, a disease killed all the potatoes in Ireland. Two million people died of hunger.Today each country has its potato dish. Germans eat potato salad, and the USA has the baked potato. Of course, the French invented French fries.Fill in the blanks according to the passage. Only one word for each blank.Potatoes were(1)______in South America 5,000 years ago.

Chen and her husband are now working far away from their hometown. Their daughter, Xiao Li, is looked after by her grandparents. Like Chen, many migrant workers(外来务工人员) are dreaming about a better life, so they have to leave their children behind.According to a survey, there are now about 61 million left-behind children(留守儿童) in poor in China. This has brought about many problems. These children care little about others. They do not do well at school. They lost confidence.Luckily many Chinese are now thinking about the life of the left-behind children and actions have been taken to help solve the problem.A charity(慈善)could take place Beijing before Children's Day. It can raise social awareness(关注) of left-behind children The event was held to raise money from businesses and the publi c to prepare “love bags”. Inside the bags, these are things for children including books, touches, and envelopes and stamps so that children can write to their parents.The event was started by Chen Weihong, a television host in China. “The left behind children don't have enough parental love and family care. They need to be in touch with their parents. We hope our love bags will help them communicate with their parents, and make them happier, ” he said.Answer the following questions according to what you read.1.
