Sure，you’ve watched extreme pet sports on Animal Planet. But did you know that there’s a whole world of athletic activities for dogs right in our area?
There are some reasons for considering taking part in such activities. Such sports strengthen the close feelings between dog and owner，and also benefit your pup’s body and mind.“ Dogs that are tied with chains often have behavioral problems，” says Lee Morgan. “They love to go out and play as much as we do.”
Of course，many of these sports require some amount of practice，and some breeds are simply better at certain activities than others .But all dogs can participate in the following games.
Frisbee Dogs（投擲游戲用的）飛盤
This sport requires you to throw as many Frisbees as your dog can catch in a 60?second time period. The further out your dog catches the Frisbee，the more points you rack up. Extra points are awarded if your pet catches the Frisbee while it’s still in the air. Mid Atlantic Disc Dogs (MAD?Dogs) hosts local competitions and offers informal instruction in local parks or even in people’s backyards.
Flyball Dogs
The sport has been around since 1970s.Flyball is a relay race with four dogs in a team. Each must jump four hurdles (跨欄) spaced with 10 feet apart and then land on a spring?loaded box that shoots out a tennis ball. The dog must then catch the ball and run back over the four hurdles. Once that’s done，the next dog can go. The first team that successfully completes the course wins the competition. There are a number of local teams，including 4 Dog Night，which holds classes for beginners and intermediate players and is always looking for new team members. The Beltway Bandits is another team，based in Leesburg，that hosts private classes and competitions

The computer keyboard helped kill shorthand---a system of rapid handwriting, and now it's threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2011, just 15% of the most 1.5 million students wrote their answers in cursive (草寫字母）.The rest? Block letters.
And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.
At Keene Mill Elementary School in Springfield, all their poems and stories are typed. Children in Fairfax County schools are taught keyboarding beginning in kindergarten. Older students who never mastered handwriting say it doesn't affect their grades.
There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?
It was at University of Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity (真實性）can be confirmed. Students also find them more fascinating.
The loss of handwriting also may be a cognitive (認(rèn)知的）opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better-a lifelong benefit.
It doesn't take much to teach better handwriting skills. At some schools in Prince George's County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript letters through second grade, and cursive letters in third grade.
There are always going to be some kids who struggle with handwriting because of their particular neurological (神經(jīng)系統(tǒng)的)wiring, learning issues or poor motor skills. Educators often point to this factor in support of keyboarding

Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags, plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys （腎臟）don't work efficiently．Your body is not thoroughly emptied of waste products．Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before developing any symptoms．There may be no warning signs. This makes early detection （診查）difficult．
Kidney's main job is to remove toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no obvious pain．
Research shows that more than 35% of the patients requiring dialysis（透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make-up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿病）and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential (潛在的) risk factors for the kidney disease．

Dear Volunteers，
The service you will provide to elderly individuals in Abilene as a Meals on Wheels volunteer is deeply appreciated. I want to take this opportunity to thank you for the many miles you will travel and all of the hours you will contribute to help make this one of the best programs in the entire state.
We have our staff members make a home visit before adding each person to the program and try to visit everyone at least once every year. That is hardly enough, and we depend on your contact a great deal! It is important that you report back when you do not get an answer to your knock on the door. The person inside may be hurt or ill. They may be in hospital or out of town and fail to inform us. If they are frequently absent, we may need to determine if they still need meals.
If you find someone with a medical emergency, please call 911 to request medical assistance, and then call the Meals on Wheels office. If you find someone who needs assistance other than for a medical emergency, please call the Meals on Wheels office at 6725050, and we will try to find the appropriate agency or individual to call.
Let us know when a certain person needs extra food. We have a food preparation room of shelf stable items to share with them. Please feel free to take a few magazines when you deliver meals. Many of those we serve cannot afford magazines and enjoy reading. If someone is interested in getting books from the Abilene Public Library, let us know. We can sign them up for the Books on Wheels program. Call if you smell gas strongly when you deliver meals, or if someone needs a space heater, a blanket, or an electric fan. Please convey all needs to us, and we will try to see that they are met. Some of the elderly people who we offer our service may have cancers, liver diseases, AIDS, etc. If you do not want to deliver meals to the people with certain types of health problems, such as these, please let us know.
Sincerely,
Betty L. Bradley, LBSW,
Executive Director

About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink seawater, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is!

  1. 1.

    People used to think that the rubbish thrown into the sea ______.

    1. A.
      wouldn't harm the fish in the sea
    2. B.
      would change the balance of the food chain
    3. C.
      would be broken down in the sea
    4. D.
      wouldn't do much harm to the sea
  2. 2.

    From the passage, we learn that ______.

    1. A.
      most fish and sea animals live at the surface of the seas
    2. B.
      it is very difficult to break the balance of a food chain
    3. C.
      excessive fishing has caused the decrease in fish stock
    4. D.
      it won't be long before the problems concerning oceans will be solved
  3. 3.

    Which of the following is NOT a way being used to protect oceans?

    1. A.
      The use of international agreements
    2. B.
      Forbidding fishing to protect fish stocks
    3. C.
      The use of new techniques
    4. D.
      Raising people's awareness of the need to protect oceans

Strange Baby-Naming Laws
Germany Parents are banned by law from using last names and the names of objects and products as first names. A child’s first name must clearly indicate his or her sex, and all names must be approved by the office of vital statistics in the area in which the child was born.
Iceland The country’s naming committee consults the National Register of Persons to determine if a name is acceptable. If parents want to go off-list, they must apply for approval and pay a fee, and the name must contain only letters in the Icelandic alphabet.
New Zealand The country’s Births, Deaths, and Marriages Registration Act of 1995 prohibits parents from choosing a name that “ might cause offense to a reasonable person; is unreasonably long; or is, includes, or resembles an official title or rank,” including, apparently, Adolf Hitler and Yeah Detroit—both names recently rejected.
Denmark If Danish parents prefer a moniker not on the list of 7,000 preapproved baby names, they must get permission from local church and government officials. Fifteen to 20 percent of the 1,100 reviewed names—including creative spellings of common names, last names as first names, and unusual names—are rejected each year

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.
Yes, that’s parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcome all the obstacles on the course and in life it is part of the philosophy(理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”
Another philosophy we’ve learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence

    Parkour has become popular throughout the world because of______.

    1. A.

Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存活) if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.     
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (懸崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks.  The faces of the desert mountains are always changing--very, very slowly--as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely

  1. 1.

    Many plants may survive in deserts when______.

    1. A.
      the rain falls only in a few weeks
    2. B.
      the rain is spread out in a year
    3. C.
      there is little rain in a year
    4. D.
      it is dry all the year round
  2. 2.

When the Japanese attacked America’s ships at Pearl Harbor on 7 December 1941, they did it secretly. The makers of the movie Pearl Harbor have behaved differently.
The noise about Pearl Harbor, made by Disney，has reached its highest point with its premiere （首次公演） before the movie opens in cinemas across the US at the start of the Memorial Day holiday weekend, a time to recall national heroes who sacrificed their lives on the battlefield.
As Ben Affleck is the main star, the movie seems sure to become a success in the United States at least.
At almost three hours in length, it promises to be a good old Hollywood movie. There is a love story. Affleck and his co-star, Josh Hartnett, both fall in love with the navy nurse, Kate Beckinsale and, of course, there is much human courage and love of country.
It’s certain that Disney will be accused of “changing” history. The showing of actual events in a movie always causes arguments.
Bits of the story are deliberately not mentioned in the movie. It does not address the theory held by some historians that President Franklin Roosevelt knew about Japan’s intention to attack the ships in Pearl Harbor．It is said he did nothing, as he was aware that such a blow would allow him to take America into the Second World War.
Japan remains sensitive about being accused of wartime atrocities （暴行）. And Disney is sensitive about its business in Japan, where it has a theme park.
Not all the reviews of the movie have been full of praise. A reviewer for Newsweek, who was given an early preview, acknowledged that the 40-minute sequence （連續(xù)鏡頭） showing the attack itself was powerful. The attack comes quite late in the movie, however, and the reviewer was less impressed with the characters and the love story.
“Almost every line of the dialogue sounds like it comes from an old movie, ” the reviewer wrote
