Passage 4
Computers exist in a wide range of sizes and power. The smallest are embedded within the circuitry of appliances, such as televisions and wrist watches. These computers are typically preprogrammed for a specific task, such as tuning to a particular television frequency or keeping accurate time.
Programmable computers vary enormously in their computational power, speed, memory, and physical size. The smallest of these computers can be held in one hand and are called personal digital assistants (PDAs). They are used as notepads, scheduling systems, and address books; if equipped with a cellular phone, they can connect to worldwide computer networks to exchange information regardless of location.
Laptop computers and PCs are typically used in businesses and at home to communicate on computer networks, for word processing, to track finances, and to play games. They have large amounts of internal memory to store hundreds of programs a

| Computers can beat chess champion Gary
Kasparov at his game, count all the atoms in a nuclear explosion, and calculate
complex figures in a fraction of a second, but they still fail at the slight
differences in language translation. Artificial Intelligence computers have
large amounts of memory, capable of storing huge translating dictionaries and
extensive lists of grammar rules. Yet, today’s best computer language
translators have just a 60 percent accuracy rate. Scientists are still unable to
program the computer with human-like common sense reasoning power. Computer language translation is called Machine Translation, or MT. While not perfect, MT is surprisingly good. MT was designed to process dry, technical language that people find tedious to translate. Computers can translate basic phrases, such as "Your foot bone’s conn A. defeating the best chess player in the world B. telling subtle differences between languages C. translating over 60 percent of difficult texts D. doing human-like common sense reasoning 我来回答: 提交
