Will Nanfang University of Science and Technology in Shenzhen announce a new beginning for China’s higher education reform? It’s too early to answer. But its presence is challenging the Ministry of Education. Even without the approval of the ministry it seems that the school is determined to move forward and enroll 50 students, so-called child prodigies(奇才), to begin classes on March l, 2011.On graduating in 2015, these students will receive a diploma unauthorized by the Ministry of Education----unlike the students of their age from the state-run universities.

The school is committed to modeling itself on Hong Kong University of Science and Technology, but if the government will not approve the school, the situation could cause a lot of trouble for those 50 students if they want to do graduate studies at other higher learning institutions. Other schools could turn their applications down for their unauthorized diplomas.

The difficulties, however, have not frightened students and their parents away. On Dec.18, 2010 more than 1,000 students and their parents visited Nanfang University of Science and Technology for interviews.

Private investment marks the school out from other higher learning institutions in the nation. Not a penny comes from the government. So the government will have no voice in how the school will be run.

The Ministry of Education has published a comprehensive plan for education reform and development between 2011 and 2020.The goal is to make China’s higher education internationally competitive. To accomplish this goal, the government should have the courage to let the educators who have big ideas try them out. The ministry should have applauded the independence. The school in Shenzhen has shown and encouraged more to do likewise.

Education reform in China has reached a new and crucial stage. Nanfang University of Science and Technology has a long way to go to prove itself competitive rather than a diploma mill.

1.Over 1,000 students and parents visited the school because _________.

A．they believe that the school will have a bright future

B．they believe the government is sure to approve the school

C．the school models itself on Hong Kong University successfully

2.The trouble the students in the school may have is that ________.

A．the government will have no voice in the school

B．they won’t receive any diploma when graduating from the school

C．other schools are unlikely to accept their diploma from the school

D．they will not learn how to be competitive

3.What does the author think of Nanfang University of Science and Technology?

A．It is another kind of diploma mill.

B．It’s impossible for the school to be competitive.

C．It will never get the approval from the Ministry of Education.

D．Its independence from the government may benefit the education reform.

4.What is the best title of the passage?

A．University of New Style.

B．China’s Education Reform.

C．Modeling Hong Kong University.

D．Authorized or Not?

You may have seen a talking parrot on a TV show, in a movie, or even in someone’s home. The parrot has learned to copy sounds that people make. Birds are not the only animals that can copy the noises they hear. Dolphins, bats, and some apes also copy sounds. Now we can add elephants to this list of copycats.

Dr. Joyce Poole is a zoologist. She studies the sounds of elephants. While she was in Kenya, she would hear strange noises made by Mlaika after sunset. Mlaika was a 10-year-old African elephant.

Mlaika lived near a highway. Dr. Poole says, “I could not tell the difference between Mlaika’s call and the distant truck noise.” She and other scientists studied Mlaika’s sounds. It turned out that Mlaika was copying the sounds of the trucks driving by. Why would Mlaika copy trucks that she heard going by on the highway? Animals that are able to copy sounds may enjoy practicing new sounds. When they are kept outside of their natural environment, they may copy unusual sounds. That may be why an elephant would copy the sound of a truck.

“Mlaika was not the only copycat elephant,” Dr. Poole says. Calimero is a 23-year-old male African elephant. He spent 18 years with two female Asian elephants. Asian elephants make chirping sounds (sounds made by birds) to talk with one another. African elephants usually do not make chirping sounds. But Calimero now does. He is copying his Asian elephant friends. Dr. Poole says that elephants need to form bonds with their family and friends. She says, “They make sounds to communicate with each other. When they are separated, they use sounds to keep in contact.”

Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones.

1.According to the passage, what does Mlaika copy?

A. The sound of people. B. The sound of trucks.

C. The sound of Calimero. D. The sound of birds.

2.Why is Calimero mentioned in the passage?

A. To clarify the meaning of copycat elephants.

B. To show the cleverness of African elephants.

C. To add another example of copycat elephants.

D. To introduce a special life skill of Asian elephants.

3.From paragraph 4, we can know ________.

A. how long it takes for an elephant to learn a new sound

B. why the African elephant can make chirping sounds

C. why the Asian elephants make noises after sunset

D. how Asian and African elephants are alike

4.According to the passage, why do some animals like to be copycats?

A. To keep in touch with nature.

B. To please people and other animals.

C. To make new friends and keep old ones.

D. To avoid the danger from the outside world.
