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.

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

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

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

A. They create more stress.

B. They’re too big and heavy.

C. They can affect the way the runners run.

D. Their heels can soften landings.      

66. 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.

67. How did the researchers do the two studies?

A. By practising.                                B. By comparing.  

C. By questioning.                                    D. By reasoning.

MONTREAL(Reuters)—Crossing the US-Canada border(邊界) to go to church on a Sunday cost a US citizen $10 000 for breaking Washington’s strict new security(安全) rules.

The expensive trip to church was a surprise for Richard Albert,who lives right on the Canadian border. Like the other half-dozen people of Township 15,crossing the border is a daily occurrence for Albert. The nearby Quebec village of St.Pamphile is where they shop,eat and go to church.

There are many such situations in these areas along the largely unguarded 5530-mile border between Canada and the US—which in some cases actually runs down the middle of streets or through buildings.

As a result,Albert says he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada,as usual. The US customs(海關(guān)) station in this area is closed on Sundays,so he just drove around the locked gate,as he had done every weekend since the gate appeared last May,following a tightening of border security. Two days later,Albert was told to go to the customs office,where an officer told him he had been caught on camera crossing the border illegally(非法).

Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country when Canadian customs stations are closed,but the US stopped a similar program last May. That forces the people to a 200-mile detour along hilly roads to get home through another border checkpoint.

Albert has requested that the customs office change their decisions on the fine,but he has not attended a Sunday church since.“I feel like I’m living in a prison,”he said.

We learn from the text that Richard Albert is ________.

A. an American living in Township 15

B. a Canadian living in a Quebec village

C. a Canadian working in a customs station

D. an American working in a Canadian church

Albert was fined because he ________.

A. failed to obey traffic rules

B. broke the American security rules

C. worked in St.Pamphile without a pass

D. damaged the gate of the customs office

The underlined word “detour” in Paragraph 5 means ________.

A. a drive through the town                 B. a race across the fields

C. a roundabout way of traveling         D. a journey in the mountain area

What would be the best title for the text?

A. A Cross-country Trip                    B. A Special Border Pass

C. An Unguarded Border                     D. An Expensive Church Visit

C

New York City was dealing with a growing public health threat Sunday after tests confirmed (證實) that eight students at a private Catholic high school had contracted(感染)the same strain of the AH1N1 flu that has ravaged (重創(chuàng)) Mexico . Some of the school’s students had visited Cancun on a spring break trip two weeks ago .

Officials reported 68 U.S. cases of AH1N1 flu in five states so far , with the latest in Ohio and New York . Unlike in Mexico , cases in the United State have been mild – and U.S. health authorities can’t yet explain why .

Last April, on a visit to the new Mall of America near Minneapolis, I carried with me a small book provided for the reporters by the public relations office. It

included a variety of “fun facts” about the mall, for example, 140,000 hot dogs are sold each week, there are 10,000 full-time jobs, 44 sets of moving stairs and 17 lifts, 12,750 parking places, 13,000 tons of steel and $ 1 million is drawn weekly from 8 ATMs. Opened in the summer of 2005, the mall was built where the former Minneapolis Stadium had been. It was only a five-minute drive from the Minneapolis St. Paul International Airport. With 4.2 million square feet of floor space ----- twenty-two times the size of the average American shopping center –the Mall of America was the largest shopping and family recreation center under one roof in the United States.

I know already that the Mall of America had been imagined by its designers, not only as a marketplace, but as a national tourist attaction. Eleven thousand articles, the small book informed me, had been written about the mall.  Four hundred trees had been planted in its gardens, $ 625 million had been spent to build it, and 350 stores were already in business. Three thousand bus tours were expected each year along with a half-million Canadian visitors and 200,000 Japanese tourists. Sales are expected to be at $ 650 million for 2008 and at $ I billion for 2009. Pop singers and film stars such as Janet Jackson and Amold Schwarzenegger visited the mall. It was five times larger than Red Square and it included 2.3 miles of hallways and used almost twice as Knott’s Camp Snoopy.

60. We know from the text that the Mall of America is _________.

A.near an old stadium                  B.close to an airport

C.higher than the Eiffel Tower          D.bigger than most American parks

61. Why are the pieces of information provided by the Mall of America referred to as “fun facts”?

A.They are largely imagined.          B.They are surprising figures(數(shù)字)

C.They give exact descriptions.        D.They make people feel uneasy.

62. Why does the author mention popular stars who have been to the mall?

A.To show its power of attraction.

B.To show that few rich people like to shop there.

C.To tell the public about a new movie being made about it.

D.To tell people that they have chances of meeting famous stars there.

63. We can infer from the text that _______.

A.Japanese visitors are most welcome to the mall

B.Canadian visitors would spend $ I billion at the mall

C.Knott’s Camp Snoopy was next to the Mall of America

D.the Mall of America was designed to serve more than one purpose(目的)
