Be careful what you say around your dog．It might understand more than you think．
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany．The dog also appears to be able to learn new words as easily as a 3-year-old child．Its word-learning skills are as good as those of a parrot or chimpanzee．
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects．Then the owner told the dog to go and fetch one of the items and bring it back．In four tests, Rico got 37 out of 40 commands right．As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words．
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew．The owner then told Rico to fetch the object, using a word the dog had never heard before．
The correct object was chosen in seven out of ten tests, suggesting that the dog had worked
out the answer by process of elimination（排除法）．A month later, Rico remembered half of the new names, which is even more impressive．
Rico is thought to be smarter than the average dog．For one thing, Rico is a border collie, a breed （品种）known for its mental abilities．In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months．
It's hard to know if all dogs understand at least some of the words we say．Even if they do, they can't talk back．Still, it wouldn't hurt to sweet-talk your dog every now and then．You might just get a big, wet kiss in return!

2 . Each year, half a million people die from brain aneurysms（动脉瘤）—when a blood vessel（血管）bursts in the brain. An aneurysm is a bulge（膨胀）in a blood vessel that can burst. If that happens in the brain, it can be deadly. For survivors, physical disabilities are often severe. They may include memory problems, loss of balance, trouble speaking and even blindness. But new technologies are increasing survival rates and reducing disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is a comedian（喜剧演员）. She uses humor to make others laugh. Now she’s working on a new show. Michael Alexander is her doctor. He operated on Beaumont Bacon after her attack. “She had bleeding in the frontal area of her brain, so right above the eyes. The part that was in the brain was about maybe the size of an egg. So, that’s a fairly large bleed.”
Ms. Bacon had a better chance at survival than most people because of Dr. Alexander. He directs the Neurovascular Center in Los Angeles. The center offers new technologies that include placing a catheter（导管）into an aneurysm, then threading wires to promote blood clots（血栓）. This technique reduces the chances of another burst blood vessel. “You don’t have to open up the skull（头盖骨）or open up the brain to do surgery. It’s all done from inside the blood vessels. So it reduces the amount of blood loss, and the recovery is much faster.”
For Beaumont Bacon’s recovery, the hospital worked to prevent problems commonly found in patients with a burst aneurysm. The problems include brain swelling that can shut down blood vessels. She spent a month in a coma（昏迷）—unable to communicate with doctors, friends and loved ones. But with a year of treatment, she recovered. Now, she is making people laugh.

3 . It was “Disabilities Day at the Capitol ” and I was there, along with hundreds of Georgians, hoping to get the attention of our legislators (立法者). My thoughts ran back to the days when I was struggling to deal with my hearing loss learning, often dependent on others to help me hear. Now I stood under the gold dome of the Georgia Capitol, a member of the disabled community claiming the rights of people with disabilities.
After the rally (集会) I followed the crowd across the street to a free lunch. Although the crowd was huge, I managed to find a place to sit. I introduced myself to the young woman on my right, Kendall. However, with my hearing loss and her serious speech disorder, a conversation with her was next to impossible.
After a few moments, I realized that Kendall’s personal attendant (护工) was not present. I asked if anyone knew where she was and found out there had been a family situation and the attendant had to leave. “But,” I said, “who’s going to feed Kendall?” My thoughts were racing: someone had to help Kendall. In admitting her need I had to at once declare my responsibility to help.
Surprisingly, Kendall spoke clearly with her eyes. It was those eyes that spoke to me that day as we were waiting for lunch. I asked if I might serve her lunch. She nodded “Yes!” and her eyes said “Thank you!”
Helping Kendall that day shows an important belief of my life: We need each other. With or without a disability, it is our need for each other that makes us have a good life.

4 . If your fingers get chilly all year round—even in the peak of summer—you’re not alone. Many people get cold hands during all of the seasons, due to a number of causes, from genetic to chronic illnesses.
Common reasons include being elderly and thin. If your hands are regularly cold or numb, however, it’s a good idea to see a doctor to rule out more serious causes. Cold hands are one of the symptoms of both anemia (贫血症) and hypothyroidism (甲状腺机能减退). Diabetes, which reduces blood circulation, can also trigger it. And if your heart is weak from heart disease, your body may prioritize sending blood to your core over your limbs.
For many others, cold hands are a sign they have a largely harmless condition called Raynaud’s disease. When any of us goes out in the cold, our bodies activate the muscles in our smallest blood vessels to make them even smaller—a survival mechanism to keep blood, and thus warmer temperatures, in our core. For people with Raynaud’s, this reaction is too strong, and instead of just a bit less blood going to their fingers, far too little gets there.
Raynaud’s is more common in women, and it most often develops before the age of 30. In fact, if you develop Raynaud’s when you’re older—usually after 40—it can be a sign of another underlying issue. That could be a smaller problem—a previous incident of frostbite (冻伤) or a sign of a more serious autoimmune condition, like lupus (狼疮).
For the majority of people living with Raynaud’s, medication won’t be necessary. However, a rare, more severe form of Raynaud’s affects less than one in 1,000 people. In these cases, blood can become completely blocked, causing sores on the hands. If they go untreated, it can lead to gangrene (坏疽) and, very rarely, amputation (截肢).

6 . My name is Matthew. I'm not someone who has many secrets，because I'm a terrible liar. But there is one huge secret that I kept for years- -I failed my driving test. I had never failed a test before, and had never even come close. Driving made me anxious , but my parents told me I had to. They signed me up for driving lessons. I had gotten a perfect score for my written permit exam , but getting behind the wheel was a different story.
But when October 30th rolled around ,my pride set in. I wanted to be like everyone else at my school , showing off the brand new license they'd gotten. Looking back on that special day,I can't remember if I was nervous. What I do remember is starting the test , pausing at a stop sign after a few seconds , and being asked by the instructor to pull over. I had received an auto-fail since my pause was indeed a pause and not a real stop. I wasn't upset that I was leaving without a license, but I was scared everyone would know that I had failed. So when I got to class, I told everyone I didn't want to take the test on my birthday.
One Friday a month later, I went to the test spot again and passed. Later that night I drove for the first time by myself, which brought to me an amazing feeling I've never experienced——but sill, I couldn't imagine ever telling anyone the truth. So I didn't. It wasn't until midway through college that I came clean. It turned out plenty of my college friends had failed too! And I gathered enough courage to speak the fact out. Yes ,I had also failed.
Now I realize failure and imperfection are two things everyone has to experience , without which one couldn't make a true man.
1. What can we learn about Matthew?| A．He was a slow learner of driving. | B．He relied heavily on his parents. |
| C．He was afraid of taking exams. | D．He was bored with telling lies. |
| A．To put an end to his lest. | B．To check his parking skills. |

| A．Failing to get a driving license. | B．Missing his birthday celebration. |
| C．Making his parents disappointed. | D．Losing face before his classmates. |
| A．Honesty is the best policy. | B．Failure is a way to grow up. |

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs. Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.
1. A greenhorn now refers to ____.
| A．a person who is new in a job | B．a new solider |
| C．a young horse | D．a cow without horns |
| A．who is good at growing plants | B．whose thumbs are of green color |
| C．whose garden is greener than others’ | D．who is younger than his neighbors |
| A．colors | B．language | C．politics | D．agriculture |
| A．In about the 16th century, a greenhorn meant an experienced soldier. |
| B．The Green Revolution may have some connection with green thumbs. |
| C．The green-eyed monster was probably created by William Shakespeare. |
| D．The green-eyed monster can be used to describe a person who is jealous. |
8 . As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
Where do the substances which pollute the water come from? There are two main sources of sewage（污水）and industrial waste . As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas . Detergents harm water birds, dissolving the natural substances which keep their feathers water - proof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead（铅）.
So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water . It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
1. Pollution of water is noticed________.| A．when the first organisms are affected |

| C．make the waste material harmless before flowing into the water |
| D．make special room in the sea for our rubbish |
9 . “To educate a girl is to educate a thousand people,” says Maimouna Samaké, a mother of six children (including five girls). “If you put one seed in the ground and rain comes, it will grow to produce many seeds.”
Samaké, one of 2,000 residents, lives in a small village, Sounkala, in one of the world’s poorest countries. Now she has a chance to see this wish come true thanks to Build On, an American non-profit organization that is building a school in her community.
For 17 years, build On has been sending American high school students overseas to create schools in places where literacy (文化) and formal education are usually out of reach. The organization has built about 300 schools in Mali, Malawi, Nepal, Senegal, Nicaragua and Haiti. Its goal is to get young Americans in mostly urban areas to get involved in education. At the same time it can bring literacy to children and adults in poor villages in the developing world.
Sounkala’s current school only has about 70 children; mud floors, poor lighting, few desks and an absence of books mean that the school is not the most ideal learning environment. Therefore they certainly could use Build On’s help.
Samaké hasn’t been to school, but she wants a better future for her five daughters, including Ramatou, 12, and Mariam, 10. “When a woman attends school, she will teach what she learns to her children,” said Ramatou, who wants to become a doctor. “She will also know how to take better care of her family.”
Build On tries to build schools for grades one to three. If things go well over those three years, they return to help build another school for grades four to six, and then set up evening adult literacy classes.
Ramatou and Mariam will not learn inside the walls of build On school since they are already in the sixth grade, but Samaké hopes that they will be able to attend evening classes to continue learning.
1. Which of the following aspects of build On is NOT mentioned in the text?| A．Its history. | B．Its goal. |

| A．in a village in a developed country |
| B．in an urban area in a developing country |
| C．in a rural area in a developing country |
| D．in an earthquake-stricken area in a developed country |
| A．Samaké only has daughters. |
| B．Samaké is well-educated. |
| C．Ramatou is a doctor. |
| D．Mariam is in the sixth grade. |
| A．people’s education conditions in poor areas |
| B．a woman’s dream of going to school |
| C．an organization that helps build schools for people in poor areas |
| D．build On’s great contributions to education |
I waited until it was my turn, walked up to the desk and started talking to the bank clerk．He had a really strange expression on his face—just sort of a blank stare．I thought he was looking at me until I realized he was staring over my shoulder．
I began to turn round to see what he was looking at and at the same moment, the outside bank guard, the one with the machine gun, came flying through the door and lay face down on the floor．Following him through the door were three absolutely frightening men wearing those horrible stocking masks．They were carrying guns; at least the one in front was carrying a pistol．
Whether or not they said anything I can’t remember to this day, or whether people just automatically put their hands up I don’t know．I put my hands up but I just didn’t know what to do．For a few moments there was just total silence, suddenly broken by the telephone ringing．I remember wondering who was on the other end of the line．Nobody answered the telephone, so it just kept on ringing and ringing, in this otherwise deathly quiet．
Then two of the masked men went to the counter, jumped over it and got the cashiers and bank clerks to start filling their bags with cash．While the two were getting the money, the one at the door covering us with the gun obviously got a bit of an anxiety attack and started swearing at them, telling them to hurry up and get a move on．
They jumped back over the counter．One of them lost his balance when he landed on the floor and fell over．The other two swore at him again．Then they left through the door, warning us, “Don’t move．Stay like that with your hands up for ten minutes．” Then they just disappeared and there was total silence．
