Прочитайте следующие слова и запомните их значение advent, n — зд, появление to transfer -передавать to utilize — использовать to consume — потреблять, расходовать to occur — происходить, случаться, to forego — предшествовать portable, adj. — переносной evident — очевидный, явный 2. Прочитайте и переведите следующие слова в словосочетания; advent of vacuum tubes, wide-spread use of, solid state devices, miniature portable transistors, reduced size, high-speed computers 3. Определите по суффиксам, к каким частям речи относятся следующие слова и переведите их. individuality, significant, significance, available, availability 4. Прочитайте текст А и ответьте Via вопрос: What are the " revolutionary" developments that changed the course of history in the field of electronics? Text A 1.In the field of electronics, there have been a number of " revolutionary" developments that have in some 2. The second " revolution" was the integrated circuit (1C), first produced and utilized in the early sixties. Just 3. However the third major " revolution" cannot be pinpointed to a precise moment in history. This " revolution" , 4, Thjs is truly significant, since a low enough cost for the 1C means that the finished product, be it a digital wrietwatch, a pocket computer or a lifesaving'fjacemaker, can be made inexpensively enough to be within the reach of almost all consumers. 5. Найдите в тексте эквиваленты следующих словосочетаний: уменьшенный размер; более высокая 6. Прочитайте текст В и ответьте на вопрос: Text В Advantages of ICs 1.An integrated circuit is a single functional block which contains many individual devices (transistors, 2. Another obvious advantage, closelyjelated to size, is the drastically lower weight ol ICs when compared Integrated circuits also offer higher reliability, simply because any given function can be implemented with fewer components. 3. Probably one of the most important advantages of ICs is the high leveLof circuit complexity made 4. The high complexity offered on a single chip has other advantages — it opens up to the user a much For example, in many applications a regulated power supply is not essential, but woj^ld irnprpye system performance. Therefore, if we had to design a ypltage regulator using discrete devices the eiecrsion would be to forego the regulator in the given system. However since available 1C voltage regulators are low cost and easy to use, we would probably Decide Jo, include the regulator and thus.etlrvance the system's performance. Another example of this kind of impact'by ICs is fn Tyr receivers. With essentially no increase in cost, TV manufacturers haye> incorporated additional (r^nessential) features like automatic fine tuning, automatic hue (color), etc., through trie use of ICs. 7.
