BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine (矿) explosion that trapped 13 miners, who had not been heard from since the early morning accident.
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates (最新报道) on the rescuers’ progress.
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a.m.—more than three hours after it happened. “It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine.
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said Roger Nicholson, general counsel from International Coal Group.
At a late night news conference, Nicholson said one team had advanced about 4,800 feet in the four hours since entering the mine just before 6 p.m. Another team entered the mine about 30 minutes later.
He said the crew was very experienced, with some members having worked underground for 30 to 35 years. The miners were equipped with about one hour of breathable oxygen (氧气) each. The company has not released the names of the miners.
The teams test the air about every 500 feet, and have to remove the power to the phones they use to communicate with the surface before doing that. “We don’t want to be energizing (通电) anything if it’s in an atmosphere with burnable gases,” Kips said. The cause of the explosion was not immediately known. High levels of carbon monoxide (一氧化碳) were detected shortly after the explosion, which delayed rescue efforts, but those levels have since subsided (减退), authorities said.
According to the passage, we can infer that ________.
A. all the miners who were trapped underground were still alive
B. communication with the trapped miners was cut off
C. the two rescue teams entered the mine at the same time
D. the rescue started as soon as the accident happened
If the first team advanced at an average speed, they could dig about ________ per hour.
A. 1,000 feet B. 2,400 feet C. 1,200 feet D. 4,800 feet
Which of the following shows the position where the miners were trapped?
![]()
Where can the passage be seen?
A. In a magazine. B. In a newspaper. C. In a science book. D. On an advertisement.
查看习题详情和答案>>Sports play an important role in British life. The most popular sport is football. Cricket is also popular in England, but is less important in the other home nations. Rugby union and rugby league are the other major team sports. Tennis is the most important sport for the two weeks of the Wimbledon Championships(温布尔登网球锦标赛)
Football
The modern global game of football developed from traditional British football games in the 19th century. Club football is organized separately in each of the home nations. English football has a league system which combines thousands of clubs. Scotland has a similar but smaller club football structure. The top level league in Wales is the league of Wales. In Northern Ireland the main league is the Irish Football League.
Each season the most successful clubs from each of the home nations qualify for(使…具有…的资格) the two Europe wide club competitions organized by UEFA(欧足联), the UEFA Champions League and the UEFA Cup.
Cricket
Cricket was invented in England. It is regarded as England’s national summer game and it is probably the second most widely covered sport.
There are eighteen professional country clubs, seventeen of them in England and one in Wales. Each summer the country clubs compete in the first class Country Championship, which consist of two leagues of nine teams and in which matches are played over four days.
Rugby
Like football, rugby union and rugby league both developed from traditional British football games in the 19th century. For much of the 20th century there was great antagonism between rugby leagues, which was a mainly working class game based in the industrial areas of northern England, and rugby union, which is a mainly middle class game in England, and is also popular in the other home nations.
Tennis
Tennis is yet another sport which originated in the United Kingdom and the governing body of the sport is the LTA(草地网球协会). However, no British man has won Wimbledon since 1936 and no British woman since 1977. The only British players of either sex to reach the world top 50 in recent years are Greg Rusedski, who learnt his tennis in Canada, and Tim Henman and Andrew Murray ,who did not pass through the LTA system either.
1.What do we know about football?

Cleveland has won the distinction of being the worst city in the United States, according to a new survey. The city has high unemployment, terrible weather, heavy taxes, and ordinary sports teams, all of which have pushed it to the No. 1 position in the Forbes.com list.
"Cleveland was the only city that fell in the bottom half of rankings in all nine categories. And it has been entitled with a less than endearing nickname: the Mistake by the lake," Forbes said on its website,
The economic downturn hit cities across the United States last year particularly in the mid-west section of the country. Crime and unemployment secured the No. 2 spot for Stockton, which held the top position in last year's ranking. Memphis got third place thanks to its violent crime rate and the number of officials who are guilty, while the poor auto industry drove the Michigan cities of Detroit and Flint into the top five.
"A lot of the cities that showed up on our list are going through hard times fight now, dealing with high unemployment, with declining producing bases. Many have experienced strong movement out of the city over the last 20 and 30 years."
Despite (尽管) its fine weather, Miami scored in the bottom 10 percent in commuting (上下班往返) time, and violent crime which sent it into sixth place.
"One of the biggest surprises is Miami. The good weather and no state income taxes blur some of the severe problems that Miami has related to crime as well as long commutes," Badenhausen added.
Florida was followed in the poor ranking by St Louis, Buffalo, Canton, Ohio and Chicago, which has the country's highest sales tax at 10.25 percent. New York, the nation's biggest city, is rich in culture but its lengthy commuting time and high income taxes pushed it into 16th place.

Thirteen vehicles lined up last March to race across the Mojave Desert , seeking a million in prize money . To win , they had to finish the 142-mile race in less than 10 hours . Teams and watchers knew there might be no winner at all , because these vehicles were missinge a key part drivers .
DARPA , the Defense Advanced Research Projects Agency , organized the race as part of a push to develop robotic vehicles for future battlefields . But the Grand Challenge , as it was called , just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance . One had its brake lock up in the starting area . Another began by throwing itself onto a wall . Another got tied up by bushes near the road after 1.9 miles .
One turned upside down . One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control . One went a little more than a mile and rushed into a fence ; another managed to go for six miles but stuck on a rock . The “winner,” if there was any , reached 7.8 miles before it ran into a long , narrow hole , and the front wheels caught on fire .
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer , who helped design two of the car-size vehicles for a company called Sci-Autonics . “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines .”
The robotic vehicles , though with necessary modern equipment such as advanced computers and GPS guidance , had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately , Sure , that very young child, who has just only learned to walk , may not think to wipe apple juice off her face , but she already knows that when there’s a cookie in the kitchen she has to climb up the table , and that when she gets to the cookie it will taste good . She is more advanced , even months old , than any machine humans have designed .

Starting high school means many changes in your life. Most teenagers look forward to the first day of high school, but still feel a little bit nervous. In order to make your high school life easier, you can follow these tips.
Learn all you can about your first day before the first day. Take part in some activities that are held at the school for new students to know the school better. If parents are invited to these activities, take yours with you. Carefully look over all the materials you receive. Be sure you know where the school’s buildings are.
Get the things you will need for class. Buy the things suggested on your teachers’ supply lists and place your materials for each class separately.
Keep up with your high school workload(工作量). If you find you’re not doing well in a subject, make use of after-school study groups or ask your teacher to help you with your schoolwork. Consider private tutoring to get you through a difficult time.
There’re more extracurricular(课外的)activities in high school than in middle school, such as clubs, music and theater groups, student government, and sports teams. Make friends and be seen at such school activities. Join a club or other organizations to meet people and develop friendships. Ask someone in school activities if you don’t know how. This is a good time to do what you like doing and an opportunity to try new things. Who said school has to be all work and no play?
Since you’ll attend more activities in high school than in middle school, you’ll have to learn how to manage you time…
