China is a nation with a rich culture in handwriting. “Even though the computer is widely used today, Chinese people should not forget the skill of writing with hands,” said a Chinese government official（官员）.

Nowadays, the computer has become a very useful tool to help people to write. As people use computers more often than before, many people have forgotten how to write Chinese characters （字）. People often make a lot of mistakes in writing.

At present, China is trying to help pupils and teachers to improve their writing with the help of information technology. With the technology, it is hoped that teachers can write their teaching contents （内容） on the blackboard and students can respond by writing, too.

The Chinese character test shows that nowadays, many college students’ handwriting has become worse. Many college students do not know how to compose （组成） words or sentences in Chinese character in the right way. Not only kids, many adults also have met the same problem. They might be able to tell the general form of a certain character. However, if you ask them to spell out the character in detail （详细地）, they can’t. On the other hand, they can easily type out the character on a computer.

In the national language teaching course, we can solve this problem with the use of certain technologies. Actually, apart from（除了）technology, there is a lot that we can do. For example, we may ask students to finish their homework by writing with hands instead of typing.

A．By punishing people who can’t write correctly.

B．By controlling people’s use of computers.

C．By using information technology.

D．By asking them to write everything with hands.

4. What does the underlined word “respond” in the third paragraph mean?
