Now let us look at how we read. When we read a printed text, our eyes move across a page in short, jerky （急动的）movement. We recognize words usually when our eyes are still when they fixate. Each time they fixate, we see a group of words. This is known as the recognition span(范围)or the visual span. The length of time of which the eyes stop ---the duration of the fixation (定位)----varies considerably from person to person. It also varies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness.
Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive (连续的) fixation. All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently (因此), for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated (孤立的) words and phrases would seem unlikely to help him in reading a continuous text.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Unlike modern animal scientists , dinosaur (恐龙) scientist cannot sit on a hillside and use telescope to watch dinosaurs in order to know how they lived and whether they were good parents . 71 .
It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils(化石) . 72 . They might have formed when an entire group of dinosaurs got stuck all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries . Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone .
73 . A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south , suggesting that they even moved long distances together .
As to whether dinosaurs cared for their young , dinosaur scientists have turned to the closest living relatives of dinosaurs —birds and crocodiles — for possible models . 74 . The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies , but we still cannot say that all dinosaurs did the same .
75 . Dinosaur scientists will have to find more proof to reach an agreement .
|
A．There is still a long way to go before the above questions could be answered . |
|
B．Though there are two different results , dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups . |
|
C．Birds give a lot of care to their young , while crocodiles just help their young to the water . |
|
D．Many fossils of the same kind of dinosaurs have been dug out from one place . |
E. Half of the dinosaurs lived alone .
F. Birds hardly pay attentions to their young .
G. Instead , they have to search hard for information from dinosaur’s fossils .

Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon (峡谷) when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region.
Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (啮齿目动物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
“This is a huge find,” says Rick Greenwood, a scientist studying the site. “I don’t think most people had any idea that those types of animals were wandering around here more than a million years ago.”
San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare.
Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils.
The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment.
“We have a confused view of what this time period was like, ” says another scientist. “A discovery like this could really be an important contribution.”
About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California.

A young man named Charles Lyell had different ideas .He wrote a book about them called Principles of Geology .The earth ,according to Lyell ,was not only thousands of years old ,it was millions of years old .As to（关于）the common belief that changes in the earth's surface happen suddenly because of a single earthquake or flood ,he said that this might happen once in a while ,but usually these changes took place very slowly .He believed that the surface of the earth had been changing from the beginning of time .The changes ,he said ,were caused by the long-term action of the winds and seas ,and by forces such as volcanoes breaking out under the earth's surface .Once in a great while he thought ,a mountain might appear for the first time after an earthquake .But usually mountains would rise slowly and steadily.? Professor Henslow was interested in Lyell's ideas ,but he did not actually believe them .Charles Darwin could not make up his mind about them .But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world.?
At Cambridge ,Charles Darwin studied just enough to pass the examination ,and received his college degree in 1831.During this time ,he had become more and more interested in geology .At the end of the school year ,he went to North Wales with one of his teachers to examine the rock formations（构成） and to search for fossils（化石）.Fossils are the remains of ancient living things .They are usually found fixed in rocks in the earth's crust（地壳）.Fossils may be of animals ,such as fish ,insects ,birds ,or humans .They may be of plants from tiny leaves to huge trees.? When a living creature dies ,it usually decays（腐烂）or is eaten by animals .However ,if it sinks into a riverbed or is quickly covered by the blowing sands of a desert storm ,the bones are kept up in the earth. Over many years the soft inner parts of a bone disappear ,leaving the inside hollow. Water containing mineral enters into the hollow. Slowly the mineral hardens and makes the bone hard and heavy,like stone.
1.According to Charles Lyell, it is mainly _______ that the earth has been formed like today's shape.?
A.from the beginning of time

2.Charles Lyell believed the fact that a mountain is formed_______.?
A.more by seas than by volcanoes
B.more slowly than suddenly?
C.more by an earthquake than by winds
D.more steadily than quickly?
3.Unlike Professor Henslow ,Charles Darwin_______.?
A.never thought Lyell's ideas were right?
B.did made up his mind not to accept Lyell's ideas?
C.thought about what the world were then thinking about?
D.thought over Lyell's ideas and developed them?
4.The main purpose of Darwin's going to North Wales was to_______.?
A.make a study of fossils
B.appreciate the rock information?
