1. (2021·昆明) 阅读理解，根据短文内容，选择最佳答案。

According to UNESCO, a large number of children in villages in some African countries like Kenya and Tanzania do not go to school. They have to work to make money for their family. And more than half of people in these countries live without electricity.

A company is now working to solve both of these problems, k has created a special solar （大阳的）power station, which is in the shape of a cow, called "Solar Cow". The company encourages parents in those poor villages to send their children to school by setting up Solar Cows at schools.

Just as its name suggests, the Solar Cow can charge batteries（给电池充电）called "Solar Milks". The Solar Milks provide electricity for the families.

The batteries can only be charged using the Solar Cow, so children have to go to school to get the electricity. Every day, children put their batteries into the bottom of their school's Solar Cow. They go to class while the batteries are being charged. At the end of the day, they take the charged batteries home.

Each fully-charged Solar Milk battery can charge a mobile phone three or four times, or a radio once or twice. The battery is also a flashlight, and it can provide ten hours of light "My father used to travel two to three hours to the charging shop to charge his phone, and it cost a lot, " a boy said. "But now, he can use the battery I bring from school to charge his phone at home. "

Since 2018, this company has set up two Solar Cows in Kenya and one in Tanzania. The company also started to raise money for more Solar Cows to help the poor children in Africa.
