Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions 12-19.
Scientists have identified two ways in which species disappear. The first is through ordinary or ‘background’ extinctions, where species that fail to adapt are slowly replaced by more adaptable life forms. The second is when large numbers of species go to the wall in relatively short periods of biological time. There have been five such extinctions, each provoked by cataclysmic evolutionary events caused by some geological eruption, climate shift, or space junk slamming into the Earth. Scientists now believe that another mass extinction of species is currently under way – and this time human fingerprints are on the trigger.
How are we are doing it? Simply by demanding more and more space for ourselves. In our assault on the ecosystems around us we have used a number of tools, from spear and gun to bulldozer and chainsaw. Certain especially rich ecosystems have proved the most vulnerable. In Hawaii more than half of the native birds are now gone – some 50 species. Such carnage has taken place all across the island communities of the Pacific and Indian oceans. While many species were hunted to extinction, others simply succumbed to the ‘introduced predators’ that humans brought with them: the cat, the dog, the pig, and the rat.
Today the tempo of extinction is picking up speed. Hunting is no longer the major culprit, although rare birds and animals continue to be butchered for their skin, feathers, tusks, and internal organs, or taken as savage pets. Today the main threat comes from the destruction of the habitat of wild plants, animals, and insects need to survive. The draining and damming of wetland and river courses threatens the aquatic food chain and our own seafood industry. Overfishing and the destruction of fragile coral reefs destroy ocean biodiversity. Deforestation is taking a staggering toll, particularly in the tropics where the most global biodiversity is at risk. The shrinking rainforest cover of the Congo and Amazon river basins and such place as Borneo and Madagascar have a wealth of species per hectare existing nowhere else. As those precious hectares are drowned or turned into arid pasture and cropland, such species disappear forever.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produced the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal "arms" or "hands." Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.
• Outside of industry, robots have also been developed and put to use by governments and scientists in situations where humans might be in danger. For example, they can be sent in to investigate an unexploded bomb or an accident at a nuclear power plant. B• In space exploration, robots have performed many key tasks where humans could not be present, such as on the surface of Mars. C• In 2004, two robotic Rovers-small six-wheeled computerized cars-were sent to Mars. D•
What is the author's attitude towards robots?
A.He appreciates them.
B.He dislikes them.
C.He thinks they are a nuisance.
D.They annoy him.
