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?
A.The time required for species to adapt to new environments
B.The variety of species found in tropical rainforests
C.The impact of human activities on Earth's ecosystems
D.The cause of the extinction of the dinosaurs

The Lord of the Rings
One of the most popular stories of the 20th century was written by John Ronald Reuel Tolkien. He was an English writer and university professor at Oxford. He was a member of an informal literary discussion group with C.S. Lewis, who was a friend of his. It was C.S. Lewis who persuaded Tolkien to publish an earlier book called The Hobbit, published in 1937. The book became popular enough for the publisher George Allen and Unwin to ask Tolkien to write a sequel to the book. This book turned out to be the three-volume novel The Lord of the Rings, which was published between 1954 and 1955.
The Lord of the Rings was meant to take off where The Hobbit ended. But the story quickly became a dark tale of the corrupting effects of the ring. When the ring was in the hands of a person who desired power, it could give power to the person. The story was divided into six books, two for each of the published volumes: The Fellowship of the Ring, The Two Towers, and The Return of the King. The book starts off with Bilbo, a character from The Hobbit. He leaves his belongings, including the ring, to a cousin named Frodo Baggins. The ring is actually the source of power of the Dark Lord named Sauron, who had been searching for the ring. Once Sauron learns who is carrying the ring, the adventure begins.
The lord of the Rings was actually a sequel to Silmarillion, a book that gives the historical background of his popular novel. In these two books, people can see that Tolkien had interests in language, religion, Roman Catholicism, fairy tales and Norse mythology.
Although The Lord of the Rings became a bestseller, the reviews of Tolkien's novel were not always favorable. Some hated the elves and others did not like Tolkien's style of writing. They dismissed it as intellectually snobbish. However, the book has been listed as the favorite work of many Europeans. C.S. Lewis said of the book, "Here are beauties which pierce like the sword or burn like cold iron." Anyone who has really read the book should agree.
Which of the following expresses the author's opinion of The Lord of the Rings?
A.It was well-written; nevertheless, some people do not like it much.
B.It caused too many arguments because of the rings.
C.It was too difficult to understand for most people.
D.It was not Tolkien's best novel among his novels about elves.
