Darwin's great work, The Origin of Species, is now generally accepted as one of the most important books ever written. But when it first came out in 1859, it was both derided and bitterly condemned by scientists and laymen.
Much of opposition to The Origin of Species arose from Darwin's claim that all living creatures, including man, are somehow related. Many people were outraged by the suggestion that man shared a common ancestor with animals such as apes and monkeys. They attacked Darwin for saying that man had descended from the apes.
But Darwin never actually said this. He believed that modern men and modern apes have both descended from the same ancestor. But at some time in pre-history, millions of years ago, men and apes began to develop separately, and ever since have continued to take on different characteristics. Today, more than 90 years after Darwin's death, this is the opinion which scientists continue to hold.
In his works, Darwin described the progression of life from its earliest forms. First came the invertebrate-creatures without a backbone. Then invertebrates evolved into fish; fish into amphibians; amphibians into reptiles; and reptiles into birds and mammals.
Fossil remains found after his death show that Darwin was right. Perhaps the most amazing fact about his theory is that he managed to work it out with the aid of only a few fossil discoveries.
Fossil remains were not the only information which we now possess but which Darwin lacked. He did not know that apes have the same diseases as men; nor that they and men have the same kind of blood. Nor did he know about the modern uses of radiation which enable scientists to tell the age of fossil remains and so estimate the speed at which evolution has taken place.
Which of the following best describes the passage as a whole?
A.The Origin of Species is a very significant book.
B.Darwin's discoveries were proved to be right though the Origin of Species was severely attacked.
C.The evolution of men has gone through a very long process.
D.It was impossible for Darwin to prove his ideas only with the aid of fossils.

Life on land probably began about 430 million years ago, though it has existed in the water for perhaps much as 3 000 million years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact, no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessary, since the plants are the only form. of life that
is able to get and store energy.
The first plants to exist out of the water were probably certain kinds of algae (海藻) which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once their move to land had been made, however, evolution (进化) took place quickly. By the end of 100 million years, plants had developed their roots (根), and some had got tree-like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had loots, leaves, wood, but mostly they had not developed seeds.
The main idea of the first paragraph is ______.
A.life on land probably began about 430 years ago
B.the first animal on land came from oceans
C.there wouldn't be animals without plants
D.plants are the only form. of life that is able to get and store energy
