“Amy! Milk!” Mama called.
Milk. It was Amy’s turn to get it. Amy sighed and shut her first-aid(急救) book.
Amy tied the cow close to a tree. Somewhere down the mountain, some volunteer doctors were teaching medical skills to village nurses. Amy heard Betty dive off hours ago. “She should have taken me with her. She thinks I’m too young.” Amy thought. “But she’s wrong. I am already 15!”
Amy carried the milk back to Mama, then wandered up the road. Roy, a village boy, was trying to stand on a horse’s back. “No wonder they don’t trust kids with anything important,” Amy thought.
She had just turned away when she heard a heavy fall and a few cries. Roy was on the ground. “Roy!” The kids nearby ran towards him. “Get Betty,” one said. Amy shook her head. “Betty’s gone to the city.”
The kids didn’t know what to do. Amy ran to Roy and saw one of his legs out of shape. A broken leg! She remembered what the first-aid book said about it.
“Victor!” Amy called to one of the boys. “Go get Roy’s mama, and find someone with a truck,” She turned to the others. “Give me your shirts. We need something to tie his leg with.”
Amy then found a strong, straight stick. She carefully wrapped the shirts around Roy’s leg and the stick. Roy cried out in pain. “I know it hurts,” Amy said softly. “But this will hold it still until you get to the hospital.”
When Amy was done, she looked up and saw Roy’s mama and a man watching beside a truck. “Thank you, Amy,” Roy’s mama said. Amy helped them lift Roy into the truck, then they drove down the hillside towards the hospital.
The next day, Betty came to Amy’s home. “I heard what you did,” Betty said. “You kept your head in an emergency. That’s an important skill.”
Amy’s face turned red. “I was afraid ...”
Betty shook her head. “It’s OK for a nurse to be afraid, as long as she has a clear head. The volunteer doctors are coming tomorrow with vaccines. We need some more hands. Can you help ”

The Vieira family moved to the United States in 1981. At that time, they decided to stop speaking Spanish at home and only communicate in English. This was because they were now living in an English-speaking country.
Now the Vieira children are adults, and they sometimes travel to Spain to visit their family and friends. But they cannot communicate with them. Unfortunately this is common. When people move to new countries, they often leave their own customs and mother language behind. This is a mistake because there are many benefits to knowing more than one language.
One advantage of speaking more than one language is that you can communicate directly with more people around the world. You do not have to depend on others to talk for you, so you’re more independent. People who know only one language must use others to help them communicate.
Furthermore, speaking a second language also allows people to experience other cultures and customs more effectively. Local expressions, vocabulary, and even jokes can have a powerful effect on a person’s understanding of another culture. So, knowing more than one language increases your knowledge of other cultures.
Finally, having more multi-language speakers improves relationships between countries. If people from different countries can communicate well, the world can become closer. Countries will then have more respect for each other and better understand each other’s problems.
The benefits of knowing more than one language are clear. In fact, there are no disadvantages. It is very sad that many people don’t try to learn another language. It is even worse when people let themselves forget their mother language and become silenced.
26．What is the passage mainly about
A．How to learn another language. B．The reasons why people come to America.
C．The importance of learning English. D．The benefits of learning other languages.
27．The passage begins with the experience of the Vieira family in order to ________.
A．discuss the need for teaching a new language
B．introduce the passage’s main characters to the readers
C．describe the advantages of moving to another country
D．show the problems of speaking only one language
28．The underlined phrase “multi-language speakers” (Paragraph 5) means “people who know ________”.
A．their mother language B．more than one language
C．a new language D．body language
29．According to the passage, if you can speak more than one language, you can ________.
A．make more friends B．find a better job
C．better understand history D．communicate more independently
30．Based on the last paragraph, which of the following is the worst
A．Not knowing another language. B．Forgetting one’s mother language.
C．Refusing to learn another language. D．Failing to communicate with others.
C
