What is it about a dog's gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin.Oxytocin is a substance in the blood that encourages bonding.Levels of oxytocin increase, for example, when a mother feeds her newborn baby.According to Nagasawa's study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs.It all started somewhere tens of thousands of years ago.Scientists believe that wolves used to follow humans who were hunting large animals.The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change.They became more loyal to their human partners.The wolves and humans started to depend on each other and bond with each other.These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them.And according to Nagasawa's study, this bond was formed with the help of oxytocin, the cuddle chemical.
11.What do we know about oxytocin？()
A.It regulates blood flow
B.It promotes bonding
C.It is in the human gene
D.It is good for health
12.When we look deeply into a dog's eyes, the levels of our oxytocin ____.
A.reduce over time
B.go either up or down
C.are on the rise
D.remain unchanged
13.At the beginning wolves followed humans to ____.
A.eat the food left by humans
B.guard against large animals
C.take humans for food
D.hunt large animals together
14.Over time some wolves turned into dogs ____.
A.due to their loyalty
B.due to the changing environment
C.for better survival
D.for better cooperation
15.What does Nagasawa9s study aim to do？()
A.Explore the role of human-wolf partnership
B.Show the characteristics of the cuddle chemical
C.Explain the bond between humans and dogs
D.Understand the evolution of species
第6题
The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there's little money around for investment that would make cities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.
In other parts of the world, increasing agricultural productivity and industrialisation went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour for factories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals, so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的) businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.
So what can be done？ Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as 65,000 dollars per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city's population grows by 5% a year, it is difficult to keep up.
76.What do we learn from the passage about cities in sub-Saharan Africa____
A.They have more slums than other cities in the world.
B.They are growing fast without becoming richer.
C.They are as modernised as many cities elsewhere.
D.They attract migrants who want to be better off.
77.What does the author imply about urbanisation in other parts of the world____
A.It benefited from the contribution of immigrants.
B.It started when people's income was relatively high.
C.It benefited from the accelerated rise in productivity.
D.It started with the improvement of peopled livelihood.
78.Why is sub-Saharan Africa unappealing to investors____
A.It lacks adequate transport facilities.
B.The living expenses there are too high.
C.It is on the whole too densely populated.
D.The local governments are corrupted.
79.In what way does the author say African cities are different____
A.They have attracted huge numbers of farm labourers.
B.They still rely heavily on agricultural productivity.
C.They have developed at the expense of nature.
D.They depend far more on foreign investment.
80.What might be a solution to the problems facing African cities____
A.Lowering of apartment rent.
B.Better education for residents.
C.More rational overall planning.
D.A more responsible government.

Amazingly，though so many people regret the rising dropout rate，our schools continue to lack formal plans—or any plans—about students’ motivation.Most schools have no game plans to ensure that students understand that school will be completely necessary.Schools expect the children to act as the school is important，but they never teach them to believe that.
Years ago，families ensured that the offspring recognized the value of school.But in many modern families，the children may fail to recognize the importance of school life just because these families may actually tell the children that school is not important.Since many families are not motivating their children to be interested students，young professionals，like teachers，may need to provide this training.Otherwise，it is likely that the dropout rate will continue to not drop，but only worsen.
Here are some strategies to convince even the most apathetic students that they must stay in school.
Ask students if they will ever need to work：The world has changed.100 years ago，factory work was the booming job，and it required no education.Today，factories are increasingly automated.Most computerrelated jobs require education and at least a high school diploma.
Ask students which century they will be prepared for：In 1900，the most common jobs were farm laborer and domestic servant—education not needed.Now，the most common jobs are office and sales worker—education and diploma usually needed.6 out of 10 people today work in a store or an office.
Ask students to devise a way that the employee could be replaced.For example，the coming trend in fast food is to use computers rather than people to run the restaurant.A prototype is apparently already being tested.The students should discover that most jobs that lack education and diploma requirements will be ripe for automation.
1.By saying “the dropout rate isn’t dropping”，the author means to say that ________.
A、most of the 9th graders can afford to go to school
B、quite a few of the 9th graders can graduate
C、the majority of the 9th graders cannot graduate
D、the minority of the 9th graders can’t graduate
2.The author’s attitude towards the schools is ________.
A、Criticism
B、Praise
C、Ignoring
D、Support
3.With the help of some professionals，________.
A、fewer students may stay in schools
B、some parents will be more convinced of their children’s future
C、the dropout rate in schools may drop
D、all the kids problems should be solved
4.What does the underlined word “offspring” probably mean？
A、friends
B、Students
C、Children
D、Parents
5.According to the passage，________ doesn’t need education.
A、an automation job of today
B、a computerrelated job now
C、an office job at present
D、a domestic servant’s job in 1900
第8题
Supporters of the new supersystems argue that these mergers will allow f or substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fiercecompetition from trucks. But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat. The vast consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such "captive" shippers 20 to 30 percentmore than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the right to appeal to the federal government’s SurfaceTransportation Board for rate relief, but the process is expensive, time-consuming, and will work only in truly extreme cases.
Railroads justify rate discrimination against captive shippers on the grounds that in the long run it reduces everyone’s cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. "Do we really want railroads to be the arbiters of who wins and who loses in the marketplace？" asks Martin Bercovici, a Washington lawyer who frequently represents shippers.
Many captive shippers also worry they will soon be hit with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to acquire one another, with Wall Street cheering them on. Consider the $10.2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrail’s net railway operating income in 1996 was just $427 million, less than half of the carrying costs of the transaction. Who’s going to pay for the rest of the bill？ Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market.
1. According to those who support mergers, railway monopoly is unlikely because ().
A.cost reduction is based on competition
B.services call for cross-trade coordination
C.outside competitors will continue to exist
D.shippers will have the railway by the throat
2. What is many captive shippers’ attitude towards the consolidation in the rail industry？
A.Indifferent.
B.Supportive.
C.Indignant.
D.Apprehensive.
3. It can be inferred from Paragraph 3 that ().
A.shippers will be charged less without a rival railroad
B.there will soon be only one railroad company nationwide
C.overcharged shippers are unlikely to appeal for rate relief
D.a government board ensures fair play in railway business
4. The word "arbiters" (Line 7, Paragraph 4) most probably refers to those ().
A.who work as coordinators
B.who function as judges
C.who supervise transactions
D.who determine the price
5. According to the text, the cost increase in the rail industry is mainly caused by ().
A.the continuing acquisition
B.the growing traffic
C.the cheering Wall Street
D.the shrinking market
