Section C Compound Dictation
In the past, one of the biggest disadvantages of machines has been their inability to work on a micro scale. For example, doctors did not have devices allowing them to go inside the human body to detect health problems or to perform delicate surgery. Repair crews did not have a way of identifying broken pipes located deep within a high-rise apartment building. However, that’s about to change. Advances in computers and biophysics have started a micro miniature revolution that allows scientists to envision and in some cases actually build microscopic machines. These devices promise to dramatically change the way we live and work.
Micromachines already are making an impact. At Case Western Reserve University in Cleveland, Ohio, research scientists have designed a 4-inch silicon chip that holds 700 tiny primitive motors. At Lucas Nova Sensor in Fremont, California, scientists have perfected the world’s first microscopic blood-pressure sensor. Threaded through a person’s blood vessels, the sensor can provide blood pressure readings at the valve of the heart itself.
Although simple versions of miniature devices have had an impact, advanced versions are still several years away.
Auto manufacturers, for example, are trying to use tiny devices that can sense when to release an airbag and how to keep engines and breaks operating efficiently. Some futurists envision nanotechnology also being used to explore the deep sea in small submarine, or even to launch finger-sized rockets packed with micro miniature instruments.
“There is an explosion of new ideas and applications,” So, when scientists now think about future machines doing large and complex tasks, they’re thinking smaller than ever before.

45.that can sense when to release an airbag and how to keep engines and breaks operating efficiently
46. when scientists now think about future machines doing large and complex tasks, they’re thinking smaller than ever before
本次复合式听写是一篇科技说明文。在过去，难以利用机器进行精细的操作（事例：医生、房屋修理人员）。但这一切都将随着机器微小型革命的发展而改变（硅片、血压感应器、安全气囊、刹车、深海探测等）。技术的发展也必然会导致思想与应用的大爆炸。
本次复合式听写难度较大。素材上是大家不太熟悉的科技性文章，填空部分也选择了较为生僻和复杂的单词与句子。细节上，38题的ing形式与43题的复数形式要多加注意。听写的三个句子更是让很多同学泪奔哪。听不懂啊有木有？同学们碰到这种情况要注意了，千万不能放弃。踩到一个点就是分数啊。第一句中，关键词是several years away，可以酌情演绎一下，虽然答案是更为先进的迷你机器给人类带来的美好愿景还是years away的，但同学若演绎为先进技术的实现还有待时日，也是可以酌情给分的。第二句难度较低，听到了airbag和brake自然会联想到汽车，与第一句的auto manufacturer相对应，所以基本可以肯定是有一种devise能够更好的控制airbag和brake咯，然后再paraphrase；第三句，抓住large and complex tasks 与thinking smaller 的对比，也可以猜测出是总结性的一个对比句。 |
