Virtual reality represents the harnessing of computer and information technology to realize a long-held vision of
humankind: the creation of a ‘dream machine’. It has often been stated that going to the cinema to watch a film
involves entering a ‘dream palace’, in which we are encouraged to 41 disbelief and make the leap into an
illusionary world. It can be argued that the history of the cinema is one in which the illusion of total immersion has
been progressively sought. Cinerama and other forms of large screen or wrap-around cinema such as the experiments
with 3D films in the 1950s, are 42 of this search for technological developments which would provide a strong
stereoscopic illusion of the depth of a scene and sense of immersion in ‘reality’. Theme parks such as Disney World
and Universal Studios also provide sophisticated versions of this film technology coupled 43 experience rides
such as Star Wars, Back to the future, in which the visual information is co-ordinated with surround sound and
movement of the vehicle.
Yet virtual reality is 44 an upgraded version of Cinerama or a theme park ride, as it achieves not only a
greater sense of presence, but through the use of computer technology has developed an interface which facilitates
‘interactivity,’ the capacity to direct one’s gaze and movements so that one can explore and move around inside the
illusory flow of images. It is this 45 between computer technology and movie-making which makes virtual
reality possible.

These satellite images show the ebb and flow of plant life on earth over three years, taken by a NASA satellite
called SeaWiFS. The blue areas are void of plants, the red spots indicate an overabundance, and the green areas show
where plants are thriving. This is the earth breathing. The plants are taking up CO2, and they’re breathing out oxygen.
As suggested by oceanographers, almost half of that activity is going on underwater. The oceans are teeming with
tiny microscopic plants called phytoplankton. They are at the bottom of the food chain, and they basically feed all sea
life. Like all plants, phytoplankton absorbs CO2 from the atmosphere.
These images show that phytoplankton boomed over the last three years. That’s one of the key benefits of these
satellite images. Over time, scientists will use them to help predict how plants might respond as we burn more fossil
fuels, and as global CO2 levels rise. Many scientists think such greenhouse gasses will cause global warming. They
suggest that it is related to recent climate change. However, what they don’t know is how life in the ocean will respond
over the long haul if CO2 levels keep rising.
46 What is the main idea of the whole text?
Satellite images of the ebb and flow of plant life show the earth breathing.
Satellite images show that phytoplankton absorbs CO2 from the atmosphere like other plants on earth.
Satellite images will prove to us that plant life in the ocean causes rising CO2 levels and global warming.
Satellite images of plant life activities can help predict how plants will respond to rising CO2 levels.
47 What do the green areas of the satellite images indicate?
The areas do not have any plants. The areas are filled with plants.
The areas are filled with lakes. The areas are filled with overabundant plants.
48 How does one know that the earth is breathing?
Because satellite images show no change in the green areas.
Because satellite images show that the plants’ breathing activities happen underwater.
Because satellite images show that plants are absorbing CO2 and producing oxygen.
Because satellite images show overuse of fossil fuels.
49 According to the passage, which statement about the phytoplankton is true?
These tiny microscopic plants underwater do not change the weather.
These tiny microscopic underwater plants migrated from the atmosphere.
These tiny microscopic underwater plants are at the top of the food chain.
These tiny microscopic plants flourished underwater over the past three years.
50 What can scientists use these images for?
To prove that phytoplankton multiplies in warm waters.
To predict possible plant responses to rising global CO2 levels.
To predict that global plants will flourish during the following years.
To prove that breathing phytoplankton leads to global warming.
