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.

本次復(fù)合式聽寫是一篇科技說明文。在過去，難以利用機(jī)器進(jìn)行精細(xì)的操作（事例：醫(yī)生、房屋修理人員）。但這一切都將隨著機(jī)器微小型革命的發(fā)展而改變（硅片、血壓感應(yīng)器、安全氣囊、剎車、深海探測等）。技術(shù)的發(fā)展也必然會導(dǎo)致思想與應(yīng)用的大爆炸。
本次復(fù)合式聽寫難度較大。素材上是大家不太熟悉的科技性文章，填空部分也選擇了較為生僻和復(fù)雜的單詞與句子。細(xì)節(jié)上，38題的ing形式與43題的復(fù)數(shù)形式要多加注意。聽寫的三個句子更是讓很多同學(xué)淚奔哪。聽不懂啊有木有？同學(xué)們碰到這種情況要注意了，千萬不能放棄。踩到一個點(diǎn)就是分?jǐn)?shù)啊。第一句中，關(guān)鍵詞是several years away，可以酌情演繹一下，雖然答案是更為先進(jìn)的迷你機(jī)器給人類帶來的美好愿景還是years away的，但同學(xué)若演繹為先進(jìn)技術(shù)的實(shí)現(xiàn)還有待時日，也是可以酌情給分的。第二句難度較低，聽到了airbag和brake自然會聯(lián)想到汽車，與第一句的auto manufacturer相對應(yīng)，所以基本可以肯定是有一種devise能夠更好的控制airbag和brake咯，然后再paraphrase；第三句，抓住large and complex tasks 與thinking smaller 的對比，也可以猜測出是總結(jié)性的一個對比句。
