B

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.

One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine. Sometimes they wore running shoes. Other times they ran barefoot.

Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.

They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.

The study appeared in the official scientific journal of the American Academy of Physical Medicine.

The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.

They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.

Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.

Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come

down first. Also, the heel generally has thick material under it to soften landings.

60. How many organizations are involved in the two studies?

A. Three.                          B. Four.                      C. Five.                      D. Six.

61. What can we learn from the text?

A. Most running shoes are designed improperly.

B. The design of high heels is better than that of running shoes.

C. No one will run with running shoes in the future.

D. Both of the studies are done in America.

62. Why do running shoes increase the risk of injuries to runners?

A. They could create stress. 

B. They’re too big and heavy.

C. They can affect the way the runners land.   

D. Their heels can soften landings.

63. How did the researchers do the two studies?

A. By practising.         B. By comparing.      C. By questioning.     D. By reasoning.

A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami(海啸) warnings just three minutes later. The country has one of the best earthquake early warning systems in the world.

There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes.

There are also concrete(混凝土) sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami.

Costas Synolakis ,a tsunami expert at the University of Southern California in Los Angeles said,"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event."

He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan.

The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas.

Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves.

Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted

Where can this passage probably be adapted from?

    A.A magazine on science       B.A fairy Tale 

C.A scientific fantasy book     D.A newspaper  

Which of the following statements NOT true ?

    A. A terrible earthquake hit the northeastern coast of Japan

    B. It was also the worst earthquake in Japan

C. The 9.0 earthquake was the fourth most powerful earthquake ever recorded in Japan

D. Japan's concrete sea walls was unable to handle such high waves.

According to Costas Synolakis, why did Japan suffer such a loss?

  A. The country has never experienced any event as big as this one over the past 150 years

B. Japan has the best earthquake early warning systems in the world.

C. There are not concrete sea walls around all of the Japanese coastline

D. The government didn’t announce its first tsunami warnings three minutes earlier.

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.
