It has long been assumed that when cats scratch objects with their front paws (爪子) that they are
sharpening their paws. 1_____ Research on cat behavior suggests that the major reason for this behavior is
communication. By scratching up the bark of a tree (or the leg of your favorite chair) the cat is letting other
cats or people know where she is and what she is up to.
Cats tend to pick a small number of noticeable objects in their environments to scratch such as trees, fence
posts repeatedly. 2_____ The scratched surface leaves a highly visible mark that can be easily seen by other
cats. In addition, cats have special glands (腺) in their paves so that when they make scratching movements
they leave scent (气味) that the cats can smell. The fact that cats leave scent marks by making scratching
movements may be the reason that cats will continue to try to scratch objects even after they have been
declawed. 3_____
We don"t know exactly what cats are communicating with their scratching. Both males and females do it.
It is done inside and outside the home and even by cats living with no other cats around. 4_____ Cats don"t
scratch up your furniture to bother you or just to be destructive, but for specific reasons, one of which is
communicating. Cats also scratch to extend their bodies, during play, and possibly as a greeting or to relieve
dissatisfaction when prevented from doing other things they want to do.
5_____ It is easier to prevent problem scratching rather than trying to change your cat"s preference for
the arm of your sofa after it has become a built up habit. Thus, the goal is to establish acceptable scratching
habits by getting your cat to prefer a scratching post rather than the arm of your sofa.
B. This is why the tree next door looks so scratched up.
C. Cats use other parts of their bodies to communicate as well.
D. Small pieces of bark have accumulated on the ground underneath.
E. Scratching can result in considerable damage, owner dissatisfaction.
F. Declawed cats may still be leaving scent marks on objects they scratch.
G. It could be a defensive warning or just a marker that announces its existence.

举一反三
power plant fired up in September, the designer, Mitsubishi, is expecting to prove it"s possible to burn coal
without polluting. This technology is known as integrated gasification combined cycle (IGCC). Proving IGCC
works should motivate Mitsubishi"s US partner, NRG Energy, to jump other hurdles to building new clean
plants.
The project promises to solve the problem of the ages for power plants: how to produce cheap, clean,
reliable electricity. No existing technology can do all three perfectly.
The problem is IGCC isn"t there yet. It costs about 20 percent more than traditional plants. And even
though it"s easier to collect the resulting carbon dioxide from an IGCC plant than a traditional plant, there"s
no proven way to get rid of the greenhouse gas. One plan is to drill a shaft (通道) to pump the carbon dioxide
underground, into saltwater formations. But there"s no guarantee it will remain underground forever.
NRG administrators think solving the IGCC riddles is worth the trouble because they expect the US will
soon limit the amount of carbon dioxide that power generators may give out.
"With the additional cost of IGCC, to just voluntarily build something that"s 20 percent more expensive,
that"s commercial suicide," NRG chief administrator, David Crane said.
NRG administrators expect the cost to decline after six or seven plants are built. But other industry experts
think it will take about a dozen plants for the price to be competitive with traditional coal plants.
Takaya Watanabe, a vice general manager of Mitsubishi, admits that the cost challenges are difficult. "It"s
good for a company to say we want to be green, but unless someone is willing to pay, it"s a dream. It won"t
keep our family eating rice," he said.
B. To produce energy without burning coal.
C. To keep the use of electricity cheaper.
D. To pump carbon dioxide more easily.
B. How to deal with the high cost.
C. How to get along with other partners.
D. How to improve the new technology.
B. It"s unlikely to build more new power plants.
C. The companies are run on a tight budget.
D. Going green is easier said than done.
explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are of course extremely interested in these types of questions. They want to explain why
we possess certain characteristics and exhibit certain behavior. There are no clear answers yet, but two
distinct schools of thought on the matter have developed. As one might expect, the two approaches are very
different from each other, and there is a great deal of debate between proponents of each theory. The
controversy is often conveniently referred to as "nature and nurture".
Those who support the"nature" side of the conflict believe that our personalities and behavior patterns are
largely determined by biological factors. That our environment has little, if anything, to do with our abilities,
characteristics and behavior is central to this theory. Taken to an extreme, this theory states that our behavior
is predetermined to such a great degree that we are almost completely governed by our instincts (本能).
Proponents of the "nurture" theory, or, as they are often called, behaviorists, claim that our environment is
more important than our biologically based instincts in determining how we will act. A behaviorist, B. F.
Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings. The
behaviorists" view of the human being is quite mechanistic. They state that, like machines, humans respond to
environmental stimuli (刺激) as the basis of their behavior.
Socially and politically, the consequences of these two theories are far-reaching. In the US, for example,
blacks often score below whites on standardized intelligence tests. This leads some "nature" proponents to
conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the
differences in scores are due to the fact that blacks are often robbed of many of the educational and other
environ mental advantages that whites enjoy, and that, as a result, they do not develop the same responses
that whites do.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our
behavior lies somewhere between these two extremes and that the controversy will continue for a long time
is certain.
B. relation between behavior and environment
C. different accounts of patterns of human behavior
D. different theories of the formation of human behavior
B. advisors
C. advocates
D. judges
B. differences between the blacks and whites
C. racial discrimination in the United States
D. different responds to intelligence tests
B. To urge scientists to do more research in social science.
C. To give us a detailed explanation of human behavior.
D. To present an argument in the field of social science.
In 2010, China"s new media industry witnessed explosive development. But with "new" comes uncertainties
and challenges. The following are brief reviews on the development of China"s new media and outlooks on
its future.
Micro-blogging (微博)
Short and convenient, micro-blogs also experienced "a big bang" in China last year, with the number of
micro-bloggers at China"s popular portal (门户网站) sina.com.cn almost doubling in less than six months.
Afterwards, the other three major web portals, including sohu.com.qq. corn and 163. corn, each set up their
own micro-blogging services. With more government officials and entities (实体) registering, China"s micro-
blogging services are expected to play a more important role in connecting the public and the governments in
2011.
Search Engines
Baidu"s position in the search engine market would face fierce challenges from sohu.com, Microsoft"s Bing
and goso.cn from the People"s Daily. Xinhua is also preparing to start its search engine together with China
Mobile, a leading company in mobile networks. Goso and Xinhua both have the advantage of providing content,
while Bing has a big edge in technology and funds. They are expected to pose threats (威胁) to Baidu in 2011.
Internet of Things
IoT refers to a network of real-world objects linked by the Internet and interacting through on-line services.
China set up its first IoT research center in Shanghai in March 2010. Within the same week, Premier Wen
Jiabao stated in the annual government report that it would "accelerate the research and development, as well
as application of the Internet of Things."
However, some experts say China"s IoT is still in an early stage, and it"ll take a long time for it to let the
public enjoy its full functions.
B. China"s new media and its future.
C. The development of China"s on-line services.
D. China"s early-stage IoT and its major functions.
B. Three.
C. Four.
D. Five.
B. Sohu.com.
C. Goso.cn.
D. China Mobile.
B. An explosive development
C. A terrible damage.
D. A demanding challenge.
always room for improvement." In previous years, I earned a 99% and a 100%. The 94% I received this
term does not reflect the hard work that I put into this course. Because of her "improvement" theory, I
got a lower grade than I deserve Is her grading philosophy morally correct?
Answer: Your teacher"s grading system may be unwise, but it is not morally wrong. A teacher deserves
wide latitude in selecting the method of grading that best promotes learning in her classroom; that is, after
all, the prime function of grades. It is she who has the training and experience to make this decision.
You can criticize her methodology. A 100 need not imply that there is no possibility of improvement,
only that a student successfully completed the course work A ninth grader could get a well-earned 100 in
English class but still has a way to go before he writes as well as Jane Austen. What"s more, grades are not
only an educational device but are also part of a screening system to help assign (分配) kids to their next
class or program. By capping her grades at 94 while most other teachers grade on a scale that tops out at
100, your teacher could risk making a student lose a chance of getting a scholarship or getting into a top
college.
What it is wrong to condemn her for is overlooking your hard work. Your hard work is worthy of
encouragement, but effort does not equal accomplishment. If scholars suddenly discovered that Rembrandt
had dashed off The Night Watch in an afternoon, it would still be The Night Watch.
I could spend months sweating over my own "paintings", but I"d produce something you wouldn"t want
to hang in your living room or your garage.
One feature of a good grading system is that those measured by it generally regard it as fair and reasonable-
not the case here. Strong feeling of anger is seldom an aid to education And so your next step should be to
discuss your concerns with your teacher or the principal.
B. worried
C. excited
D. delighted
B. knowledge
C. freedom
D. experience
B. The Night Watch was completed in half a day
C. everybody"s hard work should be encouraged
D. one is to blame for doing the work in a hurry
B. Confused.
C. Unconcerned.
D. Unfavorable.
The Child ego state is a set of behaviors, thoughts and feelings which are replayed from our own childhood.
Perhaps the boss calls us into his or her office, we may immediately get a churning in our stomach and
wonder what we have done wrong. If this were explored we might remember the time the head teacher called
us in to tell us off. Of course, not everything in the Child ego state is negative. We might go into someone"s
house and smell a lovely smell and remember our grandmother"s house when we were little, and all the same
warm feelings we had at six years of age may come flooding back.
The Child ego states are constantly being updated. For example, we may meet someone who gives us the
permission we needed as a child, and did not get, to be fun and joyous. We may well use that person in our
imagination when we are stressed to resist our old ways of thinking that we must work longer and longer hours
to keep up with everything. We might ask ourselves "I wonder what X would say now." Then on heating the
new permissions to relax and take some time out, do just that and then return to the work renewed and ready
for the challenge. Afterwards, rather than blaming ourselves for what we did or did not do, what tends to
happen is that we automatically start to give ourselves new permissions and take care of ourselves.
Alternatively, we might have had an extremely unpleasant experience yesterday which goes into the Child
ego state as an antique memory that stands in the way of our growth Positive experiences will also go into the
Child ego state as antique memories. The positive experiences can then be drawn on to remind us that positive
things do happen.
The process of analyzing personality in terms of ego states is called structural analysis. It is important to
remember that ego states do not have an existence of their own. They are concepts to enable understanding.
Therefore it is important to say "I want some fun" rather than "My Child wants some fun." We may be in our
Child ego state when we say this, but saying "I" reminds us to take responsibility for our actions.
B. explain why We become nervous
C. support the idea in Paragraph 1
D. introduce the point of Paragraph 3
B. avoid stress
C. keep up with everything
D. accept challenges
B. shows one"s wisdom
C. limits one"s thoughts
D. influences one"s actions
B. "My Child wants some fun"
C. the Child ego state
D. structural analysis
