单选题Directions: {{I}}After reading the following passage, you will
find 5 questions or unfinished statements, numbered 36 to 40. For each question
or statement there are 4 choices marked A), B), C) and D).You should make the
correct choice and mark the corresponding letter on the Answer Sheet with a
single line through the center.{{/I}} Expanded use
of computer technology, development of stronger and lighter materials, and
research on pollution control will produce better, "smarter" automobiles. In the
1980s the notion that a car would "talk" to its driver was science fiction; by
the 1990s it had become reality. Onboard navigation was one of
the new automotive technologies in the 1990s. By using the satelliteaided global
positioning system (GPS), a computer in the automobile can pinpoint the
vehicle's location within a few feet. The onboard navigation system uses an
electronic compass, digitized maps, and a display screen showing where the
vehicle is relative to the destination the driver wants to reach. After being
told the destination, the computer locates it and directs the driver to it,
offering alternative routes if needed. Some cars now come
equipped with GPS locator beacons, enabling a GPS system operator to locate the
vehicle, map its location and, if necessary, direct repair or emergency workers
to the scene. Cars equipped with computers and
cellular(蜂窝)telephones can link to the Internet to obtain constantly updated
traffic reports, weather information, route directions, and other data. Future
built-in computer systems may be used to automatically get business information
over the Internet and manage personal affairs while the vehicle's owner is
driving.
单选题 Can trees talk? Yes, but not in words. Scientists have
reason to believe that trees do communicate (交际) with each other. Not long ago,
researchers learned some surprising things. First a willow tree attacked in the
woods by caterpillars (毛虫) changed the chemistry of its leaves and made them
taste so terrible that they got tired of the leaves and stopped eating them.
Then even more astonishing, the tree sent out a special smell—a signal (信号)
causing its neighbors to change the chemistry of their own leaves and make them
less tasty. Communication, of course, doesn't need to be in
words. We can talk to each other by smiling, raising our shoulders and moving
our hands. We know that birds and animals use a whole vocabulary of songs,
sounds, and movements. Bees dance their signals, flying in certain patterns that
tell other bees where to find nectar (花蜜) for honey. So why shouldn't trees have
ways of sending message?
