Today the word "electronics" is the general usage. The center of this world is a tiny silicon plate of a few square millimeters, an integrated circuit, or a chip, as it is more commonly known. The integrated circuit is undoubtedly one of the most sophisticated inventions of man, science and technology. As the operation os an integrated circuit depends on microscopic "components", the purity of all materials and the cleanness at the plant they are produced at must be of the highest quality. In the past it took scientists and reserchers a whole lifetime to make a few thousand calculations, whereas for a modern computer this task is a matter of a few seconds. At present computers capable of performing billions of operations a second are required. In the next few years engineers will complete the work on computers of above 2 billion operations a second. It will take a few more years to produce a 10-billion operationscomputer. According to some researchers, we are close to what can be regarded as a true physical limit. But other specialists think that photons will make the operation a thousand times faster. This means that in the future it will be possible to expect the appearance of photon computers and that computations will be done by means of light. In a few decades a new age of light may replace the stil youthful electronic age. The race is going on.
We finished - это когда-то в м б или вчера Yesterday, или указатели на или AGO last month= в месяце , а week ago -неделю назад..., в таком-то году может было, те указано время когда действие было совершено в А вот Have finished - have указывает, что действие завершено сейчас и мы выбираем эту форму (это настоящее завершённое время)Вот нам сейчас и пора отдохнуть 2). Есть слово LAST значит это простое время и здесь надо выбрать форму WROTE 3). Здесь берём завершённое время , ана него указывает глагол HAVE -что действие только что завершилось,, об этом говорит следующее предложение: дайте нам ещё один текст! Потому выбор Have done! 4) have eaten уже съел и больше не могу (сейчас) Кстати в совершённом времени тоже надо знать указатели этого времени (уже already и just -только что или есть или можно мысленно подставить в предложение) 5) have become берём, потому что указатель здесь слово недавно (lately) -указатели надо знать! 6). have lost ( можно подставить только что-just или недавно) потому и просит открыть дверь сейчас, Это коротко))
