Students raise money for charity by “wugging Section D Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. If you’re looking for a new pet, don’t even think about Komodo dragons, which are the world’s largest lizards and can grow to be 10 feet long and weigh more than 300 pounds. Komodo dragons run fast and eat almost any kind of meat, including dead or live animals, other Komodo dragons and people. “ These things are powerful killing machines, says Bryan Fry, a biologist. If those reasons aren’t good enough, consider the bite of a Komodo dragon. According to a new study, it may kill prey like snakes by injecting venom. This chemical, according to Fry and his team of scientists at the University of Melbourne in Australia, can cause shock in the unlucky victim. A person or animal goes into shock when the body cannot offer enough blood to the organs to keep functioning. As a result, the body starts to shut down. Scientists have only recently begun to understand why a Komodo dragon is so deadly. Some people used to believe that a Komodo dragon’s bite contained bacteria from the mouth that would cause a severe infection in the victim’s blood. The infection would finally kill the animal. Fry says that after being bitten by a Komodo dragon, animals usually die quickly. After more studies, Fry and his team found that the Komodo dragon venom contained some of the same ingredients as snake venom. These ingredients thin the bolld and cause blood vessels to become larger. To test the venom, the scientists injected rats with it and observed that the rats became still. Fry’s work show that Komodo dragons kill their prey with venom, and not by bacteria-and gives us another reason why we should avoid coming across them. That is easy to do, since they live only on a few islands in the tropical country of Indonesia. 查看更多

A higher reading rate, with no loss of comprehension, will help you in other subjects as well as in English, and the general principles apply to any language. Naturally, you will not read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook-but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage gained will be the same whatever kind of reading you are concerned with.

The reading passages which follow are all of an average level of difficulty for your stage of instruction. They are all about five hundred words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding at four hundred words per minute, you might skim (浏览) through a newspaper at perhaps 650-700, while with a difficult textbook you might drop to two hundred or two hundred and fifty.

Perhaps you would like to know what reading speeds are common among native English-speaking university students and how those speeds can be improved. Tests in Minnesota, USA, for example, have shown that students without special training can read English of average difficulty, for example, Tolstoy's War and Peace in translation, at speeds of between 240 and 250 words per minute with about seventy percent comprehension. Students in Minnesota claim that after twelve half-hour lessons, once a week, the reading speed can be increased, with no loss of comprehension, to around five hundred words per minute.

According to the passage, the purpose of effective reading with higher speed is most likely to help you ________.

A. only in your reading of a physics textbook

B. improve your understanding of an economics textbook

C. not only in your language study but also in other subjects

D. choose the suitable materials to read

Which of the following does not describe the types of reading materials mentioned in the second paragraph?

A. Those beyond one's reading comprehension.

B. Those concerned with common knowledge.

C. Those without much demand for specialized knowledge.

D. Those with the length of about five hundred words.

The average speed of untrained native speakers in the University of Minnesota is ________.

A. about 300 words per minute

B. about 245 words per minute

C. about 650-700 words per minute

D. about 500 words per minute

According to the passage, how fast can you expect to read after you have attended twelve half-hour lessons in the University of Minnesota?

A. You can increase your reading speed by three times.

B. No real increase in reading speed can be achieved.

C. Yon can increase your reading speed by four times.

D. You can double your reading speed.
