Do dogs understand us?
Be careful what you say around your dog. It might understand more than you think.
A border collie博德牧羊犬 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(黑猩猩).
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 l0 tests, suggesting that the dog had worked out the answer by the 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 (品種)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!
小題1:From paragraph 2 we know that ____________..
A.a(chǎn)nimals are as clever as human beings
B.dogs are smarter than parrots and chimpanzees
C.chimpanzees have very good word-learning skills
D.dogs have similar 'learning abilities as 3-year-old children

小題3:Which of the following statements is true?
A.The purpose of the experiments is to show the border collie's mental abilities.
B.Rico has a better memory partly because of its proper early training.
C.The border collie is world-famous for recognizing objects.

Dear Sir,
Just over six months ago, I saw an advertisement in the Morning Mail for a set of the complete works of William Shakespeare.Your company, Cosmo books Ltd , offered this set ( eight books of plays and two books of poetry) at a “remarkable” price: fifteen pounds and fifty pence, including postage and packing. I had wanted a set of Shakespeare's plays and poems for some time, and these books looked particularly attractive, so I sent for them.
Two weeks later, the books arrived, together with a set of works of Charles Dickens which I had not ordered.So I returned the Dickens books to you, with a cheque for fifteen pounds and fifty pence for the works of Shakespeare.Two more weeks passed.Then there arrived on my door step a second set of the works of Shakespeare, the same set of novels by Dickens and a six book set of the plays of Moliere, in French.Since I do not read French, these were of no use to me at all.However, I could not afford to post all these books back to you, so I wrote to you right away instructing you to come and collect all the books that I did not want, and asking you not to send any other books until further notice.
You did not reply to that letter. Instead you sent me a bill for forty two pounds, and a set of the plays of Schiller, in German.Since then, a new set of books has arrived every two weeks, the works of Goethe, the poems of Milton, the plays of Strindberg; I hardly know what I have.The books are still all in their boxes, in the garage, and my car has to stand in the rain outside.
Please send no more books, send no more bills, send no more angry letters demanding payment.Just send one large lorry and take all the books away, leaving me only with the one set of the complete works of Shakespeare for which I have paid.
Yours faithfully,
SIMON WALKER

Anyone who ever wondered why a dying plant, say, a freshly-cut red rose may appeal to a lady friend, might take some comfort in science, which once again offers us a reasonable answer to one of the world’ s great mysteries.
Beyond a common preference in people for blue, “the long history of color preference studies has been described as ‘confusing and contradictory(矛盾的)’,” write scientists Anya Hurlbert and Yazhu Ling of England’ s Newcastle University, authors of a new study in the journal Current Biology. “This fact is perhaps surprising,” they said, “though the popularity of the concept that little girls differ from boys in preferring pink.”
But the scientists believe they have an answer to this scientific mystery, discovering women’s preference for red, hidden above the average liking for blue.
In their study, the pair quickly flashed color cards, displaying many different aspects, at 208 volunteers, mostly Britishers but with a number of Han Chinese, who moved to the United Kingdom recently. Tested in three different experiments, the researchers found out a small but significant preference for reddish colors in the female volunteers.
Puzzled, the authors realized that most of the difference between men and women came in the form of a preference for green VS red in the color cards, regardless of the other slight differences such as the slightly blue ones that everyone liked. Why might this be?
Evolution might offer an answer, they reason. Human color perception(感知), the assessment of three separate color types — red — green — blue— in our vision (視覺) is a relatively recent addition to our line of mammals(脯乳動物)
Adding weight to their argument, they found the women who are most typically feminine(女性的) on a psychological survey also had the biggest preference for reddish colors. “My love is like a red, red rose,” wrote the Scottish poet Rober Burns in 1794.
小題1:What does the first paragraph probably tell us ?
A.Scientific research can help people solve the mystery.
B.When we are tired, we can turn to science for help.
C.Science can make our study interesting and contradictory.
D.We should turn to scientific invention for comfortable life.
小題2:The word “pair” in Para.4 refers to _____.
A.boy and girlB.the two authors
C.research and resultD.pink and blue
小題3:According to the passage, ______________.
A.boys like blue better than girls
B.girls like pink better than boys
C.men like red better than women
D.men and women both like green
小題4:How did the scientist do the research?
A.By asking questionsB.By telephoning the interviewees
C.By adding numbersD.By doing experiments
小題5:What is the purpose of writing this article?
A.To sell products packed in redB.To introduce the history of color
C.To inform us of a research findingD.To analyze men’s taste for color

閱讀下面短文并回答問題,然后將答案寫到答題卷相應(yīng)的位置上(請注意問題后的字數(shù)要求)。
Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It’s wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn ____________:butterfly, backstroke, breaststroke, and crawl. I feel that one of these—the breaststroke—is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming, there are certain rules every swimmer should follow:
(1) Never swim alone! No matter how good you are in the water, don’t risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
(2) Don’t go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach. Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
(3) Don’t smoke. Swimming depends on a healthy body; good lungs are part of it.
(4) Work at any activity that builds muscles.

Why do I volunteer with Big brothers / Big sisters of America? I have many reasons. Perhaps the biggest reason is that people once volunteered to help me.
Years ago, I was on the other side of the table. I was lonely and I felt lost. It’s a little embarrassing to talk about it now, but whatever the right direction in life was, I was going the opposite way. More than once, I found myself on the wrong path. If someone hadn’t stepped in when he did, I probably wouldn’t even be here now. I’d rather be in a prison or somewhere a lot smaller and deeper.
I’ve seen the work that big brothers / sisters have been doing all over the country and I’m pleased to be part of it. I’ve never done anything that made me prouder than my volunteer work. Big brothers and sisters helped me get over sadness and depression as soon as possible. Then, if I can help anyone like they helped me, I am willing to serve for as long as they will have me serve them. There are no words to describe the joy I get from helping somebody turn their life around. Every time I think that that’s me now, I’m proud and happy.
Volunteering is how I want to leave my mark on the world. I recommend volunteering work to everybody, especially to somebody who isn’t sure where they are going in life. Helping someone find their path is often the best way to find yours. Be a volunteer, and you will find your purpose in life.
小題1:What’s the main reason why the writer volunteers?
A.He has a lot of free time.
B.He is lonely and wants to be with others.
C.He wants others to know he is a good man.

小題2:It is implied in Paragraph3 that the writer __________.
A.is eager to help others
B.often feels sad and depressed
C.hopes he will be helped at any time
D.travels around the country to help others
小題3:We can infer from the passage that the writer probably __________.
A.spent some days in prison
B.didn’t know his purpose in life
C.is dissatisfied with his life
D.doesn’t live a meaningful life
小題4:What is the writer’s purpose in writing this passage?

I fell in love with Yosemite National Park the first time I saw it, when I was 13 . My parents took us there for camping.

That has been my life’s passion ever since— 38  the rocks and mountains of Yosemite. I’ve long made Yosemite my  39 .

Every American family has its own traditions on Thanksgiving Day, and mine is no difference. Once the national holiday arrives, my mom rises early to make the meal. She puts a turkey in the oven, chops carrots and bakes pies. I’m sorry to say that the men in the family – my dad, my younger brother and myself – rarely pitch in to help. Our job is to wash the mountain of dirty dishes after the meal is over.
Around 2 pm every Thanksgiving Day, family members seat themselves around the kitchen table. Plates of turkey, vegetables, salad, rolls and pies cover it. At this point, we can hardly keep ourselves from drooling (流口水) all over our fancy clothes, but it’s not yet time to eat.
First, we must bow our heads, close our eyes and say a prayer of thanks aloud to God for giving us everything we have. Under normal circumstances, I would have no problem making a list of things I am thankful for. I grew up in a loving family. My parents, who aren’t wealthy, took out loans to help me pay for university.
But, the funny thing is, every time I sit down for Thanksgiving dinner and try to say a prayer of thanks, my mind usually goes blank. I think it has something to do with my growling (咕咕叫) stomach and all of that food sitting right there under my nose.
Eventually, though, we all finish our short prayers and dig in. To be sure, the day includes other highlights – visiting with family and watching football. But usually around 6 pm we are all ourselves stuffed like turkeys and thankful to have a nice warm bed to sleep in.
小題1:The purpose of the text is to ________.
A.tell what the family do for Thanksgiving Day
B.tell how the family spends Thanksgiving Day
C.introduce foods served on Thanksgiving Day
D.introduce the American Thanksgiving Day
小題2:On Thanksgiving Day the author’s family do the following except ________.
A.watching a movieB.making visits
C.having a big mealD.watching football
小題3:Why does the author’s mind usually “go blank” when saying a prayer of thanks?
A.He is too thankful to say a word.B.His mind is on the food before him.
C.He feels too excited to speak.D.He is shy to speak in public.
小題4:The underlined phrase “dig in” in the last paragraph is closest in meaning to “________”.
A.chat with othersB.make a hole
C.mix things upD.start eating

Beginning college is exciting: new ideas to explore, new challenges to meet and many decisions to make.Your future begins here.
However, you will find college life is different from your previous school environment. Many of us can be easily overwhelmed(壓垮)by the details of running a well-balanced life.While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you.
The following you may find of use about life on campus.
* Plan well.There are so many new things to do at a new college or university.Give yourself time to make new friends and become familiar with the campus, but don’t forget why you are there.Give some time for social activities and manage your time wisely.
* If you don’t have a “system” for planning your time now(like a day timer, a computer data book), get one.Most of all, don’t depend on your memory.
* Don’t miss the guidelines.The restrictions, rules and regulations of all kinds can usually be found in your student handbook.Consider them well-balanced food for thought.What dates are important? What pieces of paper need to be handed in? What can/ can’t you do in class? What can/ can’t you do in your student residence? Who has right for what? What do you need to complete to graduate?
* Write the word “STUDY” on the walls of our bedroom and bathroom, and maybe it will help to write it on a piece of paper and stick it on the telephone, TV and the kitchen table.Consider this—you are paying thousands of dollars for your courses. You pay every time you have to repeat or replace a course.
* Build your identity.This is the time for you to decide what to do and what not to do.Take as much time as you need to explore new ideas.Do not be afraid of the beyond.This is learning to make good choices.
小題1:What is the main purpose of the passage?
A.To describe the importance of college life.
B.To explain why college life is exciting.
C.To offer advice on college life.
D.To persuade you to go to college.
小題2:According to the passage, why is it exciting to begin college life?
A.Because you prepare for your future career and life there..
B.Because you will no longer be afraid of the beyond.
C.Because you will have more freedom at college.
D.Because professors there will provide you with many new ideas.
小題3:The underlined word “know-how” refers to___________________________.
A.a(chǎn)n understanding of how things are going at college
B.college halls where rules and regulations are presented
C.practical knowledge about how to behave and what to do at college
D.a(chǎn)n environment completely different from the one you’re used to
小題4:According to the passage, college students ___________________________ .
A.needn’t learn from those who went to college before them
B.should know what they have fought for on campus
C.spend as much time as possible on social activities
D.a(chǎn)re supposed to repeat or replace at least one course
