[填空题]Suggestions for Your Work
Annie is a longtime secretary/receptionist for two senior vice presidents at a big company. They have been doing a lot of hiring lately, and almost all of the new middle-management personnel have been interviewed by one or the other of Annie’s two bosses, so naturally they come through her office first.
Some of these people are unbelievably rude. Either they treat Annie like a piece of furniture (no hello, no eye contact) or they think she is their errand (差使) girl. Lately, Annie’s two bosses have started asking her for her impressions of job candidates. So far this week, two have been discourteous (失礼的) and dismissive, so Altair gave both the thumbs-down. Neither is getting called back for the next round of interviews.
No one knows how common this is, but if you are job hunting, it’s necessary to be aware that the dummy at the reception desk may be anything but not "just a secretary".

[单项选择]In recent years, railroads have been combining with each other, merging into supersystems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 percent of the total ton-miles moved by rails. Next year, after a series of mergers is completed, just four railroads will control well over 90 percent of all the freight moved by major rail carriers.
Supporters of the new supersystems argue that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition 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 perce

[单项选择]Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat-eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to the success of mankind.
