听力原文：F: Mr. Rice, I know we've asked you here to talk about EBS University, but before we begin, let's talk about the company. EBS Electronics seems to be enjoying a boom at the moment. Can you put some figures on that？
M: Yes ... well ... in 1990, EBS's total sales were $11 billion. But in 1996, our sales grew by more than 5 billion and the sales total for the year was $27 billion. So ... while we used to think that 15% growth was good, for some time we were reckoning on achieving 20 to 50% ... though recent developments have changed that.
F: And what about international expansion？ Where are your big growth markets？
M: Over the next five years, we'll be hiring 100,000 new employees... in Asia alone, it'll be 60,000. The real development during this period will be concentrated in East Asia—mostly in China, India and Vietnam. We're hoping that one day the market there will be as big as Europe. Over a longer period, we're also planning to expand into the Middle East and into Southern Africa. All this development is very important for the company. For example, the plans for China will bring investment up to $100 billion. A few years ago, I'd never have dreamed that we'd be selling $3 billion dollars worth of products there, which we did last year. It's hard to believe that only seven years ago we sold nothing there at all.
F: Can we talk about EBS University itself？ Can you explain—simply—how it works, and who it's for？
M: I suppose it's really similar to a community-based education system—a bit like a village school—except, of course, this is a global village. Basically, it's designed to provide education and training for every single member of staff, from the Managing Director to the newest recruit.
F: And what kind of education and training is actually on offer？
M: Well, we have core courses that everyone is required to attend. They focus on things like reducing manufacturing time as well as quality issues—both for people and services. We also offer a range of options, everything from personnel, finance to languages. We run courses, for example, in French, Japanese, Korean and Mandarin.
F: Can we turn now to the question of motivation and how you go about keeping people interested in their work？
M: We never underestimate training. It's a challenge, for example, keeping someone aged 20 skilled until they're aged 60. So we do what we can. While some employees get as much as three days' training a month, the minimum is fixed at three days a year. We also have a feedback system in the form. of a questionnaire that employees answer every six months, and in this way we can keep up-to-date with employees' opinions.
F: So you really do believe in investing in your employees？
M: That's right. We allow an amount equivalent to about 4% of an employee's salary for his or her training—to 'maintain them', if you like, because we think they're important. A piece of machinery, however, gets as much as 10%-12% of its purchase price spent oil maintenance now, I believe that people are more important than machines, so we still have a long way to go.
F: It would seem, though, that EBS is more broad-minded than many firms in its approach to educating and training its employees.
M: Well, EBS has been in a state of constant renewal since it was founded in 1938, but it wasn't until the late seventies onwards that the company started trying out new methods of training and education. EBS University was the result of those experiments and has been operating very successfully for the last fifteen years. I suppose overall what distinguishes EBS from other multinationals is that we educate all our employees and not just management.
F: Thank you, Mr. Rice, and I hope that EBS University continues to do well in its educational role.

Roger Rosenblatt's book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken by most previous studies. As Rosenblatt notes, criticism of Black writing has often served as an excuse for expounding on Black history. Addison Gayle's recent work, for example, judges the value of Black fiction by overtly political standards, faring each work according to the notions of Black identity which it put forward.
Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideological, and talking about novels and stories .primarily as instruments of ideology limits much of the fictional enterprise. Rosenblatt's literary analysis discloses relations and connotations among works of Black fiction which solely political studies have overlooked or ignored.
Writing acceptable criticism of Black fiction, however, presupposes giving satisfactory answers to a number of questions. First of all, is there a sufficient reason, other than the racial identity of the authors, to group together works by Black authors？ Second, how does Black fiction make itself distinct from other modern fiction with which it is largely contemporaneous？ Rosenblatt's idea shows that Black fiction constitutes a distinct body of writing that has an identifiable, coherent literary tradition. Looking at novels written by Blacks over the last eighty years, lie discovers recurring concerns and designs independent of chronology. These structures are thematic, and they spring, not surprisingly, from the central fact that the Black characters in these novels exist in a predominantly White culture, whether they try to conform. to that culture or rebel against it.
Black Fiction does leave some aesthetic questions open. Rosenblatt's thematic analysis permits considerable objectivity; he even states that it is not his intention to judge the merit of the various works--yet his reluctance seems misplaced, especially since an attempt to appraise might have led to interesting results. For instance, some of the novels appear to be structurally diffused. Is this a defect, or are the authors working out of, or trying to create, a different kind of aesthetic？ In addition, the style. of some Black novels, like Jean Toomer's Cane, verges on expressionism or surrealism; does this technique provide a counterpoint to the popular theme that describes the fate against which Black heroes are struggling, a theme usually conveyed by more naturalistic modes of expression？
In spite of such omissions, what Rosenblatt does include in his discussion makes for a keen and worthwhile study. Black Fiction surveys a wide variety of novels, bringing to our attention in the process some fascinating and little-known works like James Weldon Johnson's Autobiography of an Ex-Colored Man. Its argument is tightly constructed, and its forthright, clear style. exemplifies levelheaded and penetrating criticism.
Roger Rosenblatt looked at Addison Gayle's criticism of Black Fiction with a (n) __ attitude.
A．disapproving
B．consenting
C．objective
D．cautious

Escaping a fire is a serious matter. Knowing what to do before a fire breaks out can save a life. For example, people should know the safety measures to take before opening a hall door during a fire. Also, make sure everyone knows how to unlock doors that may be in the escape path. At times, a key is needed to unlock a door from the inside. So, keep the key in the lock, or, you can put the key on a key ring and put it where it can be found easily.
If you live in an apartment, know the ways you can use to get out. Show everyone in the family these routes. Stress the importance of using stairways or fire escapes, not elevators.
From most homes and the lower floors of apartment buildings, escape through windows is possible. Learn the best way of leaving by a window with the least chance of serious injury.
In a home fire, windows are often the only means of escape. The second floor window sill is usually not more than 13 feet from the ground. An average person, hanging by the fingertips, will have a drop of about six to the ground. Of course, it is after to jump a short way than to stay in a burning building. Rolling away from the building when you land.
Windows are also useful when you are waiting for help. Often you'll be able to stay in the room for several minutes if you keep the door closed and the windows open. Keep your head low in the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On a second or third floor, the best windows for escape are those which open onto a roof or balcony. From the roof or balcony, a person can either drop to the ground or await rescuer. Dropping onto cement or pavement might end in injury. Bushes, soft earth, and grass can help to break a fall. A rope ladder should be considered when the drop is too great.
In a town where the fire department acts quickly, it may be best to wait for rescuer. Close the doors and wait by an open window for help. Shout for help. Be sure to close the door before opening a window. Otherwise, smoke and fire may be drawn into the room by the draft.
From most homes you can escape a fire through the ______.
A．attic
B．garage
C．windows
D．balcony

§ [C] As demand for food rises faster than supplies are growing, the resulting food-price inflation puts severe stress on the governments of many countries. Unable to buy grain or grow their own, hungry people take to the streets. Indeed, even before the steep climb in grain prices in 2008, the number of failing states was expanding. If the food situation continues to worsen, entire nations will break down at an ever increasing rate. In the 20th century the main threat to international security was superpower conflict; today it is failing states.
A．- Rather than superpower conflict, countries unable to cope with food shortages now constitute the main threat to world security．
B．- To lower domestic food prices, some countries limited or stopped their grain exports． C
D．
