     Some students are talking about: Should the children of migrant workers (农民工) study in the cities
or in their hometowns? Here are their opinions.
SpeakerOpinions
In the cities
Kangkang     The children of migrant workers could get better educations in the cities. The
teachers and schools are better there. They could live with their parents, too.
Li Ming     Children should live with their parents. Parents can look after them well. The
children of migrant workers may feel lonely if they stay in their hometowns. They
may not go to school.
Wang Tao     Studying in a city doesn't only mean getting a better education, it means having
much more chances in the city than in their hometowns. The kids see lots of things
they wouldn't be able to see in their hometowns.
In their hometowns
Lingling

     It's easy for children to go to school in their hometowns. In the city, things are
much more difficult. First, there are so few schools for the children of migrant
workers. Second, their parents may have to change jobs often. This means the kids
may have to change schools a lot too.

Han Mei     The children of migrant workers may find it hard to adapt (适应) to life in the city.
In city school, they may get bullied (被欺负). Also, these children may fall behind
because of the different levels (水平) of education.
Lily     Studying in the city costs a lot more than studying in the countryside. The cost may
add to the burdens (负担) of the parents.
