China Science and Technology Museum was opened to the public in September 1988. But the second project was completed in May, 2000. Its main task is to spread knowledge of science and technology among the public.

    The activities of China Science and Technology Museum include popular science exhibitions, Astro­vision film shows, training education programmes and experiment exhibition programmes. The museum has an area of 40，000 square metres, of which 16, 000 square metres is for exhibition halls.

    The Astro­vision Theatre is one of the museum's major attractions and also one of the largest Astro­vision theatres in the world. It makes visitors feel they are in actual events rather than see a film. Many great science activities are often held at the museum, and the museum wants to be an important window to the world.

    Radios, telephones and televisions are widely used in the world. When you switch on the radio, you can listen. But when you use the telephone, not only can you listen to others, but also you can chat with them. However, you cannot see anything at all. Television is much better than both of them. People can watch TV and listen to it, but they cannot take part in what they see.

    Today, some people are using a new type of telephone called vision phone. With it two people who are talking can see each other. Vision phones can be of great use when you have something to show the person whom you are calling. It may also have other uses in the future. Some day you may be able to call up a library and ask to read a book right over your vision phone. You may be able to do the shopping through it too. Perhaps in the near future, vision phones will come into our everyday life.

A British woman used an ancient Chinese invention to help her son deal with a modern problem. 

Dr. Rashmi Mantri grew up in India. She was taught how to use an abacus to solve math problems when she was a little girl. After noticing her son Dhruv had great difficulty with math，she started emploving the same ancient Chinese tool to help him after school. 

In just six days，Dhruv started to show rapid progress with the abacus. He enjoyed learning on it because it was like a game. He started to learn fast and would go on to become an excellent student in math. Surprised by the progress，teachers asked Dhruv to perform with the abacus at a school meeting，where some parents even came to ask for advice on using it to help their kids. 

Known as the Fifth Invention of Ancient China，the Chinese abacus helped people so lve all kinds of math problems in ancient China and is still used today. People find that using an abacus can also improve thinking and practical abilities. In 2013, the Chinese abacus was officially listed as an intangible cultural heritage of human beings(人类非物质文化遗产). "The abacus becomes a playing tool for younger children. It feels like a game. I think the success comes because children can touch and feel an abacus and picture it in their mind. "said Dr. Mantri. 

My wife's birthday falls at the beginning of spring. On that day, I came home from work, stopped her from entering the kitchen and asked her to eat out. "Has Lily called?" she asked. I shook my head. The atmosphere(气氛) at the dinner was oppressive. My wife kept glancing at her phone, showing no signs of appetite( 胃口 ).

Early the next morning, my wife got up, dark rings around her eyes. We only have one child. When Lily still lived at home, every year we would start the grand preparations days in advance for her birthday. And after she left for college, my wife would call her from time to time. How could she ignore(忽视) all our love and forget her mum's birthday? On the way to work, I texted Lily, "Your mum didn't sleep well last night."

The next day, we were about to have dinner when there was a sound of a key rattling in the lock. In came our daughter, face red with cold, a birthday cake in her hand. "Sorry, mum. Happy birthday to you!" she said, tears welling up. Immediately, my wife pulled Lily into a hug, complaining (责备）"You silly girl, why do you come all the way back at such a time? Don't you know it is cold inside?"

Lily just stayed two hours in care of missing her classes. Seeing Lily boarding the train, my wife started blaming me for that message, yet in a better mood. I did feel I handled this matter perfectly both for my wife and my child's growth.

Later, I called my parents and told them about it. I never thought they would respond with a long silence, and then said,"How many times have you forgotten our birthdays? Has either of us ever complained?"

Most parents love the Internet and want their kids to use it. But a new survey(调查)in America finds many parents are also afraid of the online world. They worry that their kids will get in trouble with people they meet online.

The study was done online from May 5 to May 10 by Insight Research Group. It says 80% of parents are worried about kids meeting bad people online. That's because young people who largely have grown up with the Net think of it as a way of showing personal feelings. To young people, the benefits(处)of giving out some personal information to online friends outweigh(过)the risks(险)．And, the study shows they are so comfortable with the Internet that 78% of them have a personal website or blog.

Parents also realize the importance of the Internet. The survey shows 91% think the Net helps their children show their feelings, and 77% think the Internet is one of the most valuable education tools that children have. But 88% think it's important to know what their kids are doing online. Findings show both parents and children need more education about using the Internet.
