For each blank, choose the best answer from the four choices and write down on the answer sheet.

It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are (1) for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This (2) remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between (3) and memory. This is called the yon Neumann (4) . The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many (5) or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.

During my elementary school years, I used to compare my mom with my best friend Tiffany’s mom.  

Tiffany’s mom always gave her lots of money to buy the most fashionable clothes and favorite food. Her mom allowed her to do anything she liked. I really admired Tiffany. My mom didn’t give me much pocket money and she always told me that I should behave myself. I was annoyed with her.

Whenever I didn’t get what I wanted, I would complain to my mom, Tiffany’s mom would give her that! I wish she were my mom. Every time, my mom would calmly say “Poor Tiffany”. I couldn’t understand her. “She shouldn’t be feeling sorry for Tiffany!” I thought. “She should be feeling sorry for me.”

One day, I couldn’t help saying to Mom, “Poor Tiffany? Lucky Tiffany! She gets everything she wants! Why do you feel sorry for her?” I burst out crying.

My mom sat down next to me and said softly. “Yes, I do feel sorry for her. I have been teaching you a lesson that she will never be taught.”

I looked up at her. “What are you talking about?”   

Mom said with care, “One day she will really want something. Maybe she’ll find out that she can’t have it. Her mother won’t always be around to give her money, and what’s more, money can’t buy everything.”  

It took some time, but I eventually understood my mom’s words. Now I am a happy and successful woman.
