Cats are the most popular pets among Americans. So it is not surprising that there are many expressions about cats. Some cats like to catch small birds, like canaries (金丝雀). If someone looks very proud or satisfied with himself, we say he looks like the cat that ate the canary.
Sometimes, a cat likes to play with a small animal it catches.
So if you play cat and mouse with someone, you change between different kinds of behavior when dealing with another person. For example, a child might offer something sweet to his little brother and then take it away when he reaches for it.
You may have known that cats spend most of their time sleeping. Sometimes people sleep for a short time during the day. This is called a cat nap.
If you tell about something that was supposed to be a secret, we say you let the cat out of the bag. If you are not able to speak or answer a question, someone might ask if the cat has got your tongue.
Have you ever watched children in the classroom when their teacher leaves for a few minutes? “When the cat’s away, the mice will play.” will best describe that situation.
You may have heard this expression: curiosity (好奇心) killed the cat. This means being too concerned about things that are not your business might cause problems.
If your home is very small, you might say there is not enough room to swing a cat. But you probably should not try this at home!

By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.
Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.
Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US.
Mr. Green Genes is the first fluorescent (荧光的) cat in the US and probably the world, said Betsy Dresser, the center's director.
The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat's genetic sequence (次序).
If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy (治疗).
The gene, which was added to Mr. Green Genes' DNA, has no effect on his health, Ms Dresser said.
Cats are ideal for this project because their genetic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center.
To show that the gene went where it was supposed to go, the researchers settled on one that would glow.
The gene "is just a marker"， said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center's work.
"The glowing part is the fun part," she said.
Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).
51. Which of the following might be the best title for the passage?
A. A Glowing Cat B. Mr. Green Genes
C. One Cat’s Life D. An experiment on cats
52. What can we conclude from the passage?
A. Fortunately, scientists have found ways to treat diseases via gene therapy.
B. Scientists think cats’ genetic makeup is the same as that of human beings.
C. Three scientists who had discovered the gene were given Nobel Prize in Physics.
D. Scientists have managed to introduce a gene into a cat’s genetic sequence.
53. What does “settled on” most probably mean in Paragraph 9?
A. chose B. killed C. took D. raised
54. From the passage we can see that ____.
A. Mr. Green Genes was made by researchers to treat diseases
B. the cat named Mr. Green Genes can glow when it is dark
C. Mr. Green Genes is the first fluorescent cat in the world
D. Mr. Green Genes is a cat of seven months old up to now
55. Which of the following is WRONG according to the text?
A. The gene added to Mr. Green Genes’ DNA doesn’t affect its health at all.
B. The scientists came up with the idea of the glowing genes totally for fun.
C. Earlier this month glowing creatures became news all through the world.
D. Scientists had discovered the gene from the jellyfish they worked with.

Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner’s home in Boston last month and was only hurt a little on her chest.
“This story isn’t much of a surprise,” said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. “There have been lots of records of these cats surviving.”
Back in 1987, scientists studied 132 cats. All of them had been brought to a vet’s clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured.
“Being able to survive falls is a critical thing for animals that live in trees, and cats are one of them,” said Socha.
Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said.
The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position.
However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist.
“This cat (Sugar) was lucky,” Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.

Americans love dogs, all types of dogs: small dogs, big dogs, lapdogs (供玩赏的小狗). Each year, people spend billions of dollars on their four-legged pals, making sure the lovable dogs have enough food to eat and lots of toys to play with.
Dogs love people, too. They lick their faces, protect their homes. Where did these four-legged companions come from? Some scientists believe that they have found the answer.
Scientists have long known that dogs evolved from（演化） wolves. Exactly when the transformation from wolf to dog actually took place, however, remains a mystery.
Some said dogs evolved as a separate species 135,000 years ago in two parts of the world. One group of dogs developed in Europe and Asia from Asian wolves. The other group evolved in North, Central, and South America from American wolves.
Now researchers say those theories are wrong. New studies suggest that domesticated dogs first appeared 15,000 years ago in eastern Asia. Scientists also say that every modern dog descended from approximately five female Asian wolves, the mother of all modern dogs.
Scientists suspect dogs first set paws in North America by following settlers across a land bridge that once linked northern Asia and North America.
【小题1】According to recent studies, all modern dogs came from female wolves in ______.
| A．Asia | B．Africa |
| C．Europe | D．South America |
| A．dogs are scientists’ best friends |
| B．dogs are more like wolves than they are like any other animal |
| C．most dogs are from Africa |
| D．scientists have no idea how dogs evolved |
| A．tamed | B．indoor | C．intelligent | D．friendly |
| A．Why Cats Don’t Like Dogs |
| B．Barking up the Wrong Tree |
| C．Love Me, Love My Dog |

IV.阅读理解（共17小题；每小题２分，满分34分）
Like cats, geckos（壁虎）always land on their feet. If they happen to fall from a wall or leaf they’ve been climbing, a quick move of the tail makes sure that they always land on their feet first, a new study finds.
Geckos are truly built for climbing: their feet have hairy toes that can fix themselves to a wall or other vertical（竖直的）surfaces. However, geckos’ feet can’t always keep hold and they may fall to the ground. When geckos fall or jump off a wall, they always land stomach-side down. Geckos’ long tails become necessary during their falls, the new study shows.
Researchers did an experiment. They placed geckos up-side-down on the underside of a leaf. When they lost their foothold and fell, the geckos pitched （倾斜）their tails for balance. They then rotated（旋转）their tails to make their bodies rotate. As soon as they were right-side up, they stopped rotating. On average, it only took the geckos about a tenth of a second to right themselves so that they would land on their feet.
Cats use a different way to land on their feet after a fall. As their tails don’t have the power like geckos’ tails, cats can’t use them to right themselves. Instead they twist their bodies around mid-air.
Engineers are trying to build a robot that imitates the geckos’ climbing ability. A tail will be fixed to the robot to allow it to keep balance.
54. What do we know about geckos?
A. Their toes make it possible for them to walk on walls.
B. Their tails can fix them to a wall or other vertical surfaces.
C. They often land on their backs when they jump off walls.
D. It takes them a second to right themselves in mid-air.
55. How do cats avoid their injury during a fall?
A. By twisting their bodies. B. By fixing their toes to the ground.
C. By using their tails to right themselves. D. By landing upside-down.
56. Geckos’ special abilities have given engineers some new ideas to _________.
A. allow robots to climb vertical surfaces
B. reproduce geckos like robots
C. invent robots that can rotate on the ground
D. invent robots that can balance themselves using their tails
57. What is the text mainly talking about?
A. The interesting living habits of geckos. B. The differences between cats and geckos.
C. Why geckos always land on their feet. D. How geckos climb up vertical walls.

Does your pet have a slim figure? According to the Association of Pet Obesity Prevention (APOP), about half of all dogs and nearly 60% of all indoor cats are overweight. Larry Kornegay, president of the American Veterinary Medical Association, says he sees an overweight pet nearly every day, and unusually the owner is overweight. So talking about the topic can be touchy. “I talk about their pet’s health. Still, some clients take it personally.”
Here are some tips for pet weight loss:
See the vet(兽医). Have your vet put together a plan and treat any existing medical problems. Pain relief and diet changes may be required for arthritic(患关节炎的) pets, which will allow for exercise to at least begin.
Skip the crash diet (an attempt to lose weight quickly by strictly limiting the diet). A special weight-loss diet may be suggested. For example, look for the supplement which burns fat and builds muscle mass in foods. Never place any pet on a crash diet, especially cats, which can suffer a potentially fatal liver disease as a result. There’s a safe weight-loss drug for dogs you can ask your vet about.
Dine alone. “Cut out treats and resist temptation by keeping pets out of the room you’re dining in,” says Chicago vet Sheldon Rubin. You can buy low-calorie treats for dogs and cats. Rubin also recommends mini carrots, small apple slices or blueberries for dogs. What’s important is finding other ways, aside from food, to show your love. Play with your cat using an interactive toy, and take your dog for walks. Walks are great for bonding, and good for you. Studies show people are actually more willing to lose weight themselves if it also will help their pet.
Feed pets at special times. Pre-measure food carefully—don’t give them a larger meal than ever—and leave it in various places, so pets sniff it out and use the stairs. It’s fun, and it’s good exercise.
1.The underlined word “touchy” in Paragraph 1 probably means__________
A. sensitive B. exciting C. moving D. pleasant
2.What can be inferred from the passage?
A. Overweight people usually like overweight pets.
B. Pets’ weight is easier to lose than humans’.
C. Cats have a greater chance of serious liver disease.
D. Overweight people often ignore their pets’ weight.
3.Which of the following methods is healthy for your pets?
A. Providing them with mini carrots or blueberries.
B. Keeping them with you when you’re dining.
C. Supplying them with larger meals or drinks.
D. Leaving the food in a fixed place for your pets.
4.What does the passage mainly tell us?
A. How to feed pets without a crash diet.
B. The importance of pet weight loss.
C. How to help pets lose weight.
D. The problems that pets will meet.
