Ⅰ.阅读理解

A

No one can say whether human­like robots will have a sweet dream, but they will almost certainly need periods of rest that offer benefits like what sleep provides to living brains, according to new research from Los Alamos National Laboratory (LANL).

“We study spiking neural networks (尖峰神经网络), which are systems that learn much as living brains do，” said Yijing Watkins, a computer scientist from LANL. “We trained a neuromorphic (神经形态的) processor in a way how humans and other biological systems learn from their environment during childhood development.” Watkins and her research team found that the network simulations (模拟) became unstable after continuous periods of unattended learning. When they exposed the networks to states that are analogous to what living brains experience during sleep, stability was recovered. “It was as though we were giving the neural networks a good night's rest，” said Watkins.

The discovery came about as the research team worked to develop neural networks that are as close as how humans and other biological systems learn to see. The group initially struggled with stabilizing simulated neural networks undergoing unattended dictionary training, which involves classifying objects without providing examples to compare them to. The researchers expose the networks to an artificial simulation of sleep as nearly a final effort to stabilize them. They experimented with various types of noise. The best results came when they used waves of socalled Gaussian noise. These waves can make sure that the neural networks keep stable.

The group's next goal is to apply their algorithm (算法) to Intel's Loihi, a product which uses spiking neural networks to work. They hope allowing Loihi to sleep from time to time will enable it to stably process information from a camera in real time. If it can confirm the need for sleep in artificial brains, we can probably expect the same to be true of human­like robots and other intelligent machines that may come about in the future.

[语篇解读]　本文是一篇说明文。主要介绍了洛斯阿拉莫斯国家实验室的一项最新研究表明，机器人运行一段时间后也需要一段时间的休

息，这种休息带来的好处与睡眠给人类带来的好处类似。

1．What did Watkins and her research team find?

A．Neural networks are far from stable.

B．Artificial brains may need break as well.

C．Neural networks are very sensitive to noise.

D．Human­like robots need equal rest to humans.

解析：选B　细节理解题。根据第一段“No one can say whether human­like robots will have a sweet dream, ..., according to new research from Los Alamos National Laboratory (LANL).(洛斯阿拉莫斯国家实验室的一项最新研究表明，没有人能说类人机器人是否会做一个甜美的梦，但它们几乎肯定需要休息一段时间，这种休息带来的好处与睡眠给人类带来的好处类似)”以及第二段“Watkins and her research team found that the network simulations became unstable after continuous periods of unattended learning.(沃特金斯和她的研究团队发现，在连续的无人值守学习后，网络模拟变得不稳定)”可知，沃特金斯和她的研究团队发现人造大脑可能也需要休息。故选B项。

2．What does the underlined word “analogous” in Paragraph 2 mean?

A．Contrary.　　　　　　B．Beneficial.

C．Similar.    D．Related.
