最近一项调查表明，在我国献血者所献的血液中有C5％是O型血，O型血在紧急情况下是必不可少的，因为在紧急的情况下根本没有时间去验受伤者的血型，而O型血可以供任何人使用。O型血的独特性在于它和一切血型都相合，任何血型的人都可以接受它，也正是因为它这种独特性，O型血长期短缺。由此可知 ()

A．血型为O型的献血者越来越受欢迎

B．O型血的特殊用途在于它和大多数人的血型是一致的

C．输非O型血给受血者必须知道受血者的血型

D．在我国C5％的人的血型是O型，O型是大多数人共同的血型

My oldest child, Emma, just returned to campus after a long holiday break to finish up her last period of college. These days, friends and family have begun flooding me with one question: What is she going to do after graduation?

The job market is, after all, awfully tough. Just this month the Federal Reserve Bank published a study showing that “recent graduates are increasingly working in low-paid jobs or working part-time.” The bright spot, according to the study, is for students who majored(主修) in STEM— science, technology, engineering and mathematics — areas in which recent graduates “have tended to do relatively well”.

But Emma is a student of the humanities(人文) at a small college. She’s an American Studies major with a focus on the politics and culture of food. For quite a while, I think her field of study is so fashionable right now that I’m not the least bit worried she will find a good job. Yet the more I’ve thought about it, the more I’ve decided to be honest. “I’m not sure what Emma is going to do,” I now say. “But she’s gotten a great education and has really found her interest. — and I know those things will serve her well over the course of her life.”

Nowadays, more and more universities and colleges are being measured by the salaries of their recent graduates. In this climate, encouraging your kid to study the humanities, seems, at best, unwise or, at worst, unconcerned with earning a living. But a college is not a vocational(职业) school. And promoting STEM subjects should not be society’s only answer to helping the next generation grow in a competitive world.

From the beginning, we never urged Emma to pick a college or a major with an eye on its expected return on money, as more and more families are doing. To Emma, what really matters will be something that we may not be able to measure for quite a long time: Emma’s contribution to the world and how happy she is in it.

"What does the middleman do but add to the price of goods in the shops " Such remarks are aimed at the intermediate operations between manufacturers and final customers. This practice usually attracts a lot of attention from the public and the press and the operation most talked about is what is often called wholesaling.The wholesaler buys goods in large quantities from the manufacturers and sells them in smaller parcels to retailers, and for this service his selling price to the retailer is raised several percent higher. But his job is made more difficult by retail demand not necessarily running level with manufacturers’’ production. Because he adjusts or regulates the flow of goods by holding stock until required, he frees the manufacturer, to some extent, from the effect on production of changing demand and having to bear the whole risk.The manufacturer can then keep up a steady production flow, and the retailer has no need to hold heavy stocks, who can call on the wholesaler for supplies any time. This wholesale function is like that of a valve in a water pipe. The middleman also bears part of the risk that would otherwise fall on the manufacturer and also the retailer.The wholesaler provides a purely commercial service, for which he is too well rewarded. But the point that is missed by many people is that the wholesaler is not just someone adding to the cost of goods. It is true one could eliminate the wholesaler but one would still be left with his function: that of making sure that goods find their way to the people who want them.

The wholesaler regulates the flow of goods by________.

A．running level with manufacturers’ production

B．holding down stock of commodities

C．keeping stock for per demand

D．adjusting the prices of goods in time
