Officials in the Midwestern U. S. town of Joplin, Missouri, say the death from Sundays’ big tornado reaches 116 and that search efforts continue for possible survivors trapped in rubble (碎石). Search and rescue teams are conducting their third sweep through the nearly 10 kilometer – long and one – kilometer wide area of destruction left by the tornado. They are working as quickly as possible while weather conditions remain relatively stable. More storms are forecast for the area.

Joplin Fire Chief Mitch Randles said there are areas with large piles of rubble that might hold survivors. “We are still finding individuals. We did rescue seven individuals from underneath rubble yesterday and, of course, we are also finding dead folks as well.” Said more folks and that is why we are doing these searches. We want to make every opportunity that we can to find everybody that is in the rubble and that has survived to this point.”

Randles said the current sweep involves a slower pace that previous searches and that he plans a fourth search, possibly on Wednesday, using specially trained dogs. “We are searching every structure that has been damaged or destroyed in a more in-depth manner, “he said.” I have dogs and dog handlers coming from all over the country do help us in that effort.”

Joplin City Manager Mark Rohr said the Red Cross and other volunteer organizations are helping people who were left homeless by the tornado and that the Federal Emergency Management Agency, or FEMA, is on hand to help. “Joplin is a great city. We have suffered a great loss, “said Rohr.” We will recover and we will recover strongly and we have a lot of help and a lot of volunteers to make that easier.”

The tornado that struck Joplin was classified by the Natioonal Weather Service as an F – 4, with winds of more than 300 kilometers per hour. It lasted only 20 minutes, but it killed more that 100 people, injured more than 400 others, and destroyed or heavily damaged some 2,000 homes, businesses, churches and a hospital. Authorities have registered more than 1,700 calls about missing people and they hope to resolvemost of those cases soon, as victims are identified and survivors come forth and reunite with loved ones.

This was the worst tornado to strike the United States in 60 years. It was the latest in a wave of violent storms that have swept Midwestern and southern states in recent weeks, leaving more than 300 people dead an causing more than $2 billion dollars in damage.

“Don’t go down to that pond — it's dangerous!” Stephanie angrily shouted at her children. She’d overheard them talking about playing near the water on the golf course close to their apartment. It was a Saturday, and 8-year-old Jeremiah was heading outside with his 11-year-old sister, Tiara, and their 13-year-old cousin, Evon McDuffie. They often went to the George Wilson Community Center in Newark, Delaware, just three houses away from their apartment building.
The Wilson center was a good place of activity for the community, especially in warm weather. But January 20, 2006, was a rainy day with winds. It’s a good day to play inside the center. Unfortunately, the three children had other ideas.
Taking no notice of what Stephanie had said, Evon, Tiara and Jeremiah walked beyond the tree line at the back of the community center and headed toward the large pond. The kids climbed through a gap in the fence, then passed a No Entering sign posted on a metal gate nearby. As they reached the pond, they also walked by a No Skating sign.
Tiara and Evon first stepped on the surface ice, and when it held, the children went out on the pond. Evon shouted out to Jeremiah, “I bet you can't cross the whole thing.”
“I bet you I can,” Jeremiah replied, and he took off across the pond.
He made it to the other side, but as he came back, Jeremiah stepped on the thinner ice. The thin surface collapsed under his feet, and the boy sank into the cold water. Evon raced back to the apartment for help, while frightened Tiara tried to reach Jeremiah as he struggled to keep his head above water. But he kept slipping beneath the surface.
When firefighters arrived, all they could see was Jeremiah's coat floating on the water. As the unconscious child was rushed to the hospital, his life was saved, for now, but the effects of hypothermia (降低体温) and lack of oxygen left Jeremiah with serious brain damage.

Vans, Keds, Dollies—they sound like the names of rock bands, but if you have teenagers, you'll know they're actually the latest in teenage footwear.

But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future.

Here, the experts identify the problems caused by teenagers' shoe choice.

KEDS/VANS

Slip-on shoes with elastic (弹性的）sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.

The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.

BALLET PUMPS

The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems.

“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait（步法）, this leads to short- and long-term problems such as calluses（茧子）, heel and knee pain.”

WEDGES AND STILETTOS

These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer's body weight forward, making them very unstable.

Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain.

SCHOOL SHOES

So what do podiatrists（足科医生）have on their wish list, especially for everyday wear?

Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark's, Marks & Spencer or Rhino.

If your teen insists on wearing 'bad' shoes, get them some simple foot orthotics(矫形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often transform their walk and halt the damage.

1. Of all the shoes mentioned in the passage, which can cause the worst problems?

  A. Marks & Spencer.                       B. Wedges & Stilettos.   

C. Keds and Vans.                     D. Ballet Pumps.

2. Which pair of shoes may not be found on the podiatrists’ wish list?

3. The underlined word “halt” in the last paragraph probably means _______.

A. increase           B. worsen           C. stop           D. cure

4. From this passage we can infer _______.

  A. trendy shoes may ruin teenagers’ health

B. fashionable shoes all have orthotics in them

  C. experts are strongly against wearing popular shoes

  D. podiatrists are expert at producing branded shoes

5. In which column of Mail Online can you find this passage?

  A. Sports.          B. Science.           C. Health.             D. Shopping.
