1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Artificial Intelligence (AI) could help promote the development of material science and accelerate the invention of new materials, according to Chinese experts. “Many core technologies that need breakthroughs in China are related    1     the material science, and AI could help in these areas.” Zhao Zhongxian, an academician of the Chinese Academy of Sciences (CAS),     2     won China’s top science award, said at a science forum     3    (open) in Dongguan, Guangdong Province.     4    (tradition) methods for material composition analysis are time-consuming(耗时的) and expensive.     5     takes an average of 10 years to develop materials and 20 years for production. With AI, the development and application cycle of new materials is expected     6     (short) by more than half.

Wang Weihua from the Institute of physics under CAS said AI is changing the way new materials are discovered. Through machine learning of material data, AI could outperform many material scientists     7     make a more efficient prediction of new materials. The fast development of AI also needs support from the material science. With emerging intelligent robots, wearable medical devices and IoT systems(物联网系统)， future smart sensors     8     (require) good sensitivity, flexibility and stability.

AI and material science are     9    (close) related, and material research could offer a solution for AI–related sensitive components, Zhao said. As for what the future with AI technology will be like,     10     (let) us wait and see.

2 . The United Arab Emirates (UAE) is mostly a desert. However, this has not stopped the country from creating great building projects. On September 26, UAE officials announced another ambitious project — Mars Science City. Expansive deserts and miles of coastline provide plenty of options for safe rocket launches (发射). And its position on the Earth makes it especially appealing as the spin of the Earth provides an extra push, meaning less fuel is needed to get payloads into orbit. All these seem to make it possible.

The Mars City Project, designed by Bjarke Ingels Group, or BIG, will provide a realistic model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE’s Mars 2117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed bin Rashid, Prime Minister and ruler of Dubai, says, “The UAE seeks international support to develop technologies that benefit humans, and lay the foundation of a better future for more generations to come.”

Built outside Dubai, the 1.9 million square feet city is expected to cost $135 million. It will consist of several dome-shaped laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the word will be invited to conduct research to come up with methods to create food, water and energy, using techniques which can be copied onto the red planet. The living spaces, where the researchers can live for up to a year, will simulate the planet’s conditions as much as possible.

The research city will also include a museum featuring famous space achievements to help educate and inspire children to undertake space exploration and discovery. To discover whether the construction method works on Mars, the museum’s walls will be 3D printed using the sand from the nearby desert. Now, if they would only add some living quarters for the general public to experience life on Mars without leaving Earth, life would be perfect.

3 . When people find out that I am a journalist, they often ask me: What do you think about the future of newspapers?

I tell them that I think the future of communications is moving online. People expect me to be fearful for the future of print. After all, in some people's minds I wouldn't be able to build a career in journalism if it all moves online. However, strangely enough, I’m actually comforted by the fact that online journalism is becoming usual. I am a blogger who has always been able to find a home for my writing online.

Since I began writing blogs, I have become aware of how many people you can reach with online writing. Compare this to the newspapers circulation base, and you will have a strong reason for online journalism.

In her successful blog post titled The Job I have spent the last year learning is not the one I will have, author Jenny Surane states, "Print is an expensive product to love. And general managers, publishers and editors must now figure out a profitable way to get their news into readers' heads.” She goes on to state that people don't feel like picking up a newspaper now and would rather scroll(滚屏) through their Twitter feed, and get news from many different sources.

If print is dying, then a new form of communicating information is being born. The need for information has not died. If anything, it has increased. What has died, rather, is the way in which information is presented.

Now more than ever, in this age of information, there is a desire for stories on the same topic from different points of view. The printing industry can keep pate with the need of providing a variety of sources, if it chooses to.

Is the future of print grim? Maybe, But is the future of journalism of communicating information to people, grim as well? Definitely not.
