Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and headaches to house fires.     1    

The theory is that the bees navigation (导航) systems are damaged by the radiation that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home.     2    

The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them.     3     Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been ruined by this,” he explained, “twenty-nine of my forty hives are now empty.”

    4     However, the fact that bees are disappearing in very large numbers is real. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years!     5     If the mobile phone theory is correct, we need to do something about it immediately—before it’s too late.

A.Bees are losing their way.
B.Nobody has proved the theory is true.
C.More evidence is provided to support the theory.
D.It is believed they are dying far from their hives.
E.Without bees, the crops can’t continue to grow.
F.The situation needs to be evaluated by the world’s best scientists.
G.One theory even blames mobile phones for the disappearance of bees.

文章大意:本文是说明文。文章讲述了去佛罗里达看海牛的经历,并阐述了海牛的生活习性,来佛罗里达的原因。

【推荐1】When most people go to the famous amusement parks in Orlando, Florida, they miss some of the natural wonders the State has to offer. It was in Citrus County on the beautiful west coast of Florida that we went to see the manatee (海牛), which occupies coastal waters and rivers.

Our days started early in the morning at Homosassa Springs. We boarded a boat with Captain Traci Wood from Native Vacations. Having spotted two manatees just below the water, Captain Traci stopped the boat as they slowly swam toward us. They used their tails to drive themselves, steering with their flippers(脚蹼), gracefully moving their bodies through the water in our direction. Our boat was soon surrounded by other members of this gentle species.

Soon we continued our journey. Within a few minutes Captain Traci stopped the boat again and we were given instructions. Whatever you do, she said, remember the three golden rules: minimize splash (拍水) noise; act with very slow movements; and when you touch one of these friendly, gentle grey giants on the back or stomach, never touch with more than one hand at a time. The Endangered Species Act forbids touching a manatee unless it touches you first, and they will let you know. The protection of this endangered species is taken very seriously. But this won’t affect the experience in the least. Most Homosassa manatees are very social and will come to you.

Manatees feed strictly on plants, and they eat a great variety of species, including hyacinth and water lettuce. They’re very big, measuring 3 to 5 metres and weighing as much as 1,600 kilos. Despite this, they look very cute. Manatees are of course wild creatures, although when face to face with them, you’re unlikely to feel any fear.

From December to March, groups of manatees escape the cold winter ocean and bathe in the warm waters near power plants and coastal springs that stay about 23 degrees year-round. Divers and swimmers come to Florida from all over the world for a chance to swim or interact with the manatee in its natural environment, rich in marine vegetation. This rich source of food makes this area an ideal place for the manatees. So the manatees arrive every year by the hundreds to find warmth, nourishment(营养) and maybe, just maybe, to visit us, the curious humans.

1. According to Captain Traci, those who swim with manatees mustn’t________.
A.be under the age of twelveB.make any noise to annoy them
C.swim so slowly as to be caught by themD.touch them with both hands at the same time
2. What can be learned about manatees from the passage?
A.They live on other sea animals.B.They are not dangerous to humans.
C.They remain curious about humans.D.They are among the biggest sea animals.
3. Why do manatees come to Florida every year?
A.To stay away from the cold weather.B.To interact with human beings.
C.To give birth to their babies.D.To clean their bodies.

文章大意:这是一篇记叙文。文章讲述的是作者和一头小牛之间的故事,父母买了一头小牛,作者很喜欢它并为它取名Tubby,后来Tubby被杀留作吃肉,作者每次吃牛肉时都很难过。

【推荐2】My folks bought their first house in the early 1940s after Dad got a better job in Marquette, Michigan. We lived just inside the city limits in what was still a rural area.

In the spring of 1948, when I was 6 years old, my parents bought a calf (小牛) to replace our cow, which had been killed the year before. So one day we drove to a local farm and returned with a white and brown calf we named Tubby.

We didn’t own a truck, so Tubby rode home in the backseat of Dad’s car with my 9-year-old brother, Steve and me. As you can imagine, the trip was a lot of fun for us kids.

Later that summer, Mom thought it would be cute to take a picture of me sitting on Tubby’s back. All went well until the flashlight of the camera sent Tubby charging off on a run, with me holding on for dear life and my heart pulled to my throat.

I lasted for about 30 feet before I hit the ground. Mom was quick enough to shoot a follow-up picture, so we had photos of me both on and off Tubby!

When summer had passed, the day arrived for poor Tubby to fill our freezer (冰柜). I must have been somewhere else with my mom on the fateful (决定性的) day, because I have no memory of what happened. All I knew was that the barn (畜棚) was empty, and that we had plenty of meat for dinners.

I hadn’t lived on the farm like my mother, so I didn’t understand that what had happened to Tubby was not unusual. Livestock (家畜) aren’t meant to be pets, and most farm kids know and accept the truth.

Whenever we had beef for dinner, I would tearfully ask, “Is this Tubby?” This went on for a couple of months until Dad had enough and declared, “No more cows!” That made me feel better about poor Tubby.

1. Why did the parents buy Tubby?
A.To raise it for meat.B.To produce enough milk for the kids.
C.To keep the kids company.D.To have Tubby help with farm work.
2. What can we know from the passage?
A.The writer witnessed Tubby killed.
B.The writer felt happy to see the freezer filled with meat.
C.The writer’s mother thought it natural to kill Tubby for meat.
D.The writer felt excited on Tubby’s back when it was running off.
3. How did the writer feel towards Tubby whenever he had beef?
A.Sad.B.Thankful.C.Moved.D.Hopeless.

【推荐3】Birds don’t need lessons in building nests. Fish don’t need coaching to learn how to swim. All animals have instincts. They’re born with natural abilities to do certain things. Wild animals also learn by copying their parents and practicing. And pets learn through training.
But instincts and training aren’t the only keys to animals’ behavior. Scientists say animals’ thoughts and feelings also influence their actions. Animals often make choices, plans, and sensible changes. They can help others and solve problems. Some even make and use tools!
If animals could talk, what would they say about their thoughts and feelings? A gorilla (大猩猩) born in captivity (关在笼子里) has helped answer that question. Koko, a gorilla, was taught to use sign language. She has learned hundreds of words!
Koko once had a pet cat she named All Ball. “Koko love Ball,” she signed. “Soft good cat.” One time, she blamed the cat for biting her by signing “You bad dirty toilet!” When her pet died, Koko cried. “Sad for sleeping cat,” she signed.
Koko calls herself “fine animal gorilla”. She uses sign language to argue, joke, and ask and answer questions.
“Most animals can’t use words to tell us their thoughts,” says Dr. Jonathan Balcombe. “But Koko shows us that animals have their own ideas and feelings.” Dr. Balcombe is a scientist at the Humane Society of the United States. He says there’s even more to discover about animals through field studies. In field studies, people watch animals in their natural environment.
“Scientists who study animals’ natural behaviors learn how animals live and think,” Balcombe says. “That knowledge can help others respect every animal who shares the planet with us.”
1. The underlined word “instincts” in Paragraph 1 probably refers to the ability that ________.
A.animals copy their parentsB.animals learn by practicing
C.animals are born withD.animals learn through training
2. The example of Koko shows that ________.
A.an animal likes to have its own petB.an animal can learn to speak through training
C.an animal has the natural ability to speakD.an animal can speak its mind
3. According to Balcombe, learning how animals live and think can ________.
A.help people care for animalsB.teach animals to use words
C.train animals to use toolsD.train animals to be cleverer
4. What might be the best title for the passage?
A.Raising animals as petsB.Understanding animals
C.Training animals to speakD.Protecting animals from danger
