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 from 30 to 34.
In today's competitive world, what responsible parent would not want to give their children the best possible start in life? For this reason, many parents want their children, often as young as ten months old, to become familiar with computers. They seem to think that if their children grow up with computers, they will be better equipped to face the challenges of the future.
No one has proved that computers make children more creative or more intelligent. The truth may even be the opposite. Educational psychologists claim that too much exposure to computers, especially for the very young, may negatively affect normal brain development. Children gain valuable experience of the world from their interaction with physical objects. Ten-month-old babies may benefit more from bumping their heads or putting various objects in their mouths than they will from staring at eye-catching cartoons. A four-year-old child can improve hand-eye coordination and understand cause and effect better by experimenting with a crayon than by moving a cursor around a computer screen. So, as educational psychologists suggest, instead of government funding going to more and more computer classes, it might be better to devote resources to music and art programs.
It is ludicrous to think that children will fall behind if they are not exposed to computers from an early age. Time is too precious to spend with a "mouse". Now is the time when they should be out there learning to ride a bike. There will be time later on for them to start banging away at keyboards
What would be an appropriate title for this passage?
Let kids be kids
Computers in schools
Never too early to start
More computers mean brighter future

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 from 35 to 42.
Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to
expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.
Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.
However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments
What does the passage mainly discuss?
The time required for species to adapt to new environments
The variety of species found in tropical rainforests
The impact of human activities on Earth's ecosystems
The cause of the extinction of the dinosaurs

Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.
However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments
According to the passage, natural evolutionary change is different from change caused by humans in that changes caused by humans ______
affect fewer ecosystems
are occurring at a much faster rate
are less devastating to most species
are reversible
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 from 35 to 42.
Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to
expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.
