GUATEMALA CITY(Reuters)---- A fish that lives in mangrove swamps(紅樹沼澤)across the Americas can live out of water for months at a time, similar to how animals adapted(適應)to land millions of years ago, a new study shows.
The Mangrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圓木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida .
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(過渡)form water onto land, ” Wright said.
小題1:The Mangrove Rivulus is a type of fish that ________.
A.likes eating nuts
B.prefers living in dry places
C.is the longest living fish on earth
D.can stay alive for two months out of water
小題2:Who will write up a report on mangrove Rivulus?

D.Scott Taylor.
小題3:According to the text, lungfish can __________.
A.breathe through its skin
B.move freely on dry land

小題4:What can we say about the discovery of Mangrove Rivulus?
A.It was made quite by accident.
B.It was based on a lab test of sea life.
C.It was supported by an American magazine.
D.It was helped by Patricia Wright.

The Maum Sin Yong School says that they are the first in Colorado and the one of only two schools in the US to teach martial arts (武術) to students with mental diseases.
“They do everything that our regular classes do,” says Rob Hansen, Tae Kwon Do instructor. Hansen teaches the kids how to punch (拳打), kick, and block along with the values of the Korean martial arts. He says that they also learn confidence and how to improve their motor skills. “They’ve learned focus, just to be able to pick one item and pay attention to it.”
“Tae Kwon Do is pretty fun,” says Christina Hinkle. She was born with Down syndrome (唐氏綜合癥) and says she never wants to miss class. “Well, how come? It’s pretty fun.”
“Ever since she saw Karate Kid, she’s been running around the house, doing kicks and punches,” says Peggy Hinkle, Christina’s mother. Peggy says that her daughter processes information slowly and taking Tae Kwon Do lessons has helped her in all parts of her life. “It gives her a chance to be a regular kid.”
Wednesday’s class is not a normal class. Instead, it’s a day that all the students have been waiting for. “Today is actually the first day, and I’m actually going to be able to test these guys,” says Hansen. The students would receive their White Belts. However, in order to receive their belts, the students must show off their skills in front of a group of Black Belts.
“Nervous? No way. I’m so excited,” says Christina just before she displayed what she has learned over the past few months. She and the other students also answered questions about the history of Tae Kwon Do, as well as its philosophy (哲學).
“To me, it’s just really important for them to actively see that they are learning something,” says Hansen. “That they actually are able to be rewarded for everything that they’ve done in this class.” All the students passed. They received their White Belts.
“To see the joy in her face was very rewarding,” says Peggy. She videotaped the whole test and hugged her daughter telling her that she’s proud. “Christina feels like she could do anything,” she says.
Christina says that her next goal is to keep working on her skills so she can move up to a Gold Belt. She says, “Oh, my God, I can’t believe I got the first rank.”
小題1: The purpose of teaching the students with mental disease Tae Kwon Do is _______.
A.to help them gain confidence and be skilled at concentration
B.to enable them to punch and kick the other opponents
C.to take part in tournament and win prize.
D.to get rid of their mental diseases and run motorcar
小題2:Wednesday is the time ________ according to the text.
A.when the students with mental disease will begin to learn Tae Kwon Do
B.when Hansen’s students will give a display of what they have learned.
C.when Hansen’s students will replace their black belts with white belts.
D.when the parents can see how Hansen teach their children with mental disease.

A.children are learning Tae Kwon Do with their parents’ company.
B.Rob Hansen is a strict coach of teaching Tae Kwon Do

 For almost forty years the Empire State Building in New York City was the world's tallest skyscraper(摩天大樓). The building reaches a height of 1, 250 feet. It has 102 floors. The use of steel frames made its height possible. Steel walls can rise height without needing to be thick. Steel frame construction is strong. All plates are fixed firmly together by metal bolts(螺栓)called rivets (鉚釘). When set in place, rivets are usuall red- hot. One end is already rounded. A riveter uses a special hammer to shape the other end. Then the rivet cools. It holds the plates firmly. High winds can move this strong building. A wind of a hundred miles an hour has caused it to move almost one and a half inches.
 小題1:The writer says that the Empire State Building ________.
A.hasn’t been finished

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.
The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer — Mauritius was to become the fourth country in the world to issue stamps.
Before the order was filled and delivered, a ball was planned at Mauritius’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words “Post Office” instead of “Post Paid” on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue’s rareness and age, collectors have paid as much as $16 800 for it.
小題1:Over a century ago, Mauritius _______.

A popular student in her small high school, Katie started college, expecting to do well in her courses and be best friends with her roommates. But things didn’t turn out that way. Psych 101, the course she thought would be a first-semester favorite, turned out to be a struggle.
Living away from home tends to be the toughest adjustment for first-year students. You may feel homesick in your first weeks or months. It can help to call, write, or email your parents and friends, making them know how you’re going. You can also talk with your roommates. As first-year students themselves, they’re probably experiencing many of the same fears and worries that you’re dealing with .
But what if you don’t get along well with your roommates?
In some cases, it can be a good thing if you and your roommates aren’t much alike. Different views on things may be helpful, so respect your differences no matter what.
If you and your roommates don’t get along well, it can help to find someone who you feel does understand you, which should be easy on a campus with so many people. Many schools have student organization nights where all of the campus clubs gather and promote their organizations, so you can meet people with the same interests there as you. You’ll also meet tons of people in class or in your dorm building.
As homesickness, painful throats, sprained (扭傷的) ankles and wisdom teeth that act up are common among college students, you should check out your student guidebook or your school’s website to find out information about the university health center.
If you think you cannot deal with your problems, make a stop at the school counseling (咨詢)center. First-year troubles are something the counselors know well. You can get help there.
小題1:From Paragraph 1 we can infer that __________.
A.Katie had been worried about the changes before starting her college life.
B.Katie felt satisfied when her college life started.

After more than a year of bitter political debate, President Obama sat down in the White House East Room on March 23 and signed the 2010 Patient Protection and Affordable Care Act into law with a pen,and then another pen,and another. Obama used 22 pens to sign the $938 billion health care bill.
The practice of using different pens to sign important legislation(法規(guī))dates at least as far back as Franklin Roosevelt. The reason is fairly simple. The pen used to sign historic legislation itself becomes a historical artifact. The more pens a President uses, the more thank-you gifts he can offer to those who helped create that piece of history. The White House often give pens to supporters of the newly signed legislation. When Lyndon Johnson signed the Civil Rights Act in 1964, he reportedly used more than 75 pens and gave one of the first ones to Martin Luther King Jr. And in 1996, President Clinton gave the four pens he used to sign the Line-Item Veto bill to those most likely to appreciate the bill's consequence.
Once they're given away, some pens end up in museums; others are displayed proudly in recipients'(接受者) offices or homes. But they sometimes appear again, like in the 2008 presidential campaign(競選活動), when John Macain promised to use the same pen given to him by President Reagan to cut pork from the federal budget.
Not every President goes for the multipen signature, however. President George W. Bush preferred signing bills with only one pen and then offering several unused "gift" pens as souvenirs.
小題1:.We can learn from paragraph 1 that the 2010 Patient Protection and Affordable Care Act        .
A.has been passed easily
B.was put forward one year ago
C.becomes law in the USA
D.is unimportant
小題2:How are the pens dealt with after being used by President Obama?
A.Supporters of the newly signed legislation are likely to get some of them.
B.Obama will keep them.
C.They will be just set aside
D.They will be sold to the public at a high price.
小題3:What can we learn about John Macain?
A. He was ever President in the USA.
B. He took part in the 2008 presidential campaign.
C. He never used the pen given by Reagan.
D. He was only concerned about his own business.   
小題4:What does this passage mainly tell us ?
A. Obama signed the 2010 Patient Protection and Affordable Care Act.
B. It is a practice to use multiple pens to sign important legislation in the USA.
C. Pens are necessary in the signature.
D. All the presidents like the multipen signature.

Rusian Presidnet Vladimir Putin made a surprise visit early Saturday to the southern Russian town of Beslan where commandos (突擊隊) stormed the school to end the hostage crisis. He accused the attackers of trying to spark an racial conflict that would engulf (卷入)Russia’s troubled Caucasus Mountains region.
