第1题
翻译文段 However simple, any machine is a combination of individual components generally r
eferred to as machine elements or parts. Thus, if a machine is completely dismantled, a collection of simple parts remains such as nuts, bolts, springs, gears, cams and shafts - the building block of all machinery. A machine element is, therefore, a single unit designed to perform a specific function and capable of combining with other elements. Sometimes certain elements are associated in pairs, such as nuts and bolts or keys and shafts. In other instance, a group of elements is combined to form a subassembly, such as bearings, couplings, and clutches.

By 1800 more than a thousand steam engines were in use in the British Isles, and Britain r
etained a virtual monopoly on steam engine production until the 1830s. Steam power did not merely spin cotton and roll iron; early in the new century, it also multiplied ten times over the amount of paper that a single worker could produce in a day. At the same time, operators of the first printing presses run by steam rather than by hand found it possible to produce a thousand pages in an hour rather than thirty. Steam also promised to eliminate a transportation problem not fully solved by either canal boats or turnpikes. Boats could carry heavy weights, but canals could not cross hilly terrain; turnpikes could cross the hills, but the roadbeds could not stand up under great weights. These problems needed still another solution, and the ingredients for it lay close at hand. In some industrial regions, heavily laden wagons, with flanged wheels, were being hauled by horses along metal rails; and the stationary steam engine was puffing in the factory and mine. Another generation passed before inventors succeeded in combining these ingredients, by putting the engine on wheels and the wheels on the rails, so as to provide a machine to take the place of the horse. Thus the railroad age sprang from what had already happened in the eighteenth century.

The idea is as audacious as it altruistic: provide a personal laptop computer to every sch
oolchild—particularly in the poorest parts of the world. The first step to making that happen is whittling the price down to $100. And that is the goal of a group of American techno-gurus led by Nicholas Negroponte, the founder of the fabled MIT Media Lab. When he unveiled the idea at the World Economic Forum in January it seemed wildly ambitious. But surprisingly, it is starting to become a reality. Mr. Negroponte plans to display the first prototype in November at a UN summit. Four countries—Brazil, Egypt, Thailand and South Africa—have said they will buy over 1 m units each. Production is due to start in late 2006.

How is the group, called One Laptop Per Child (OLPC), able to create a laptop so inexpensively？ It is mainly a matter of cleverly combining existing technologies in new ways. The laptop will have a basic processor made by AMD, flash memory instead of a hard disk, will be powered by batteries or a hand- crank, and will run open-source software. The $100 laptop also puts all the components behind the screen, not under the keyboard, so there is no need for an expensive hinge. So far, OLPC has got the price down to around $130.
But good news for the world's poor, may not be such great news for the world's computer manufacturers. The new machine is not simply of interest in the developing world. On September 22nd, Mitt Romney, the governor of Massachusetts, said the state should purchase one for every secondary-school student, when they become available.
Sales to schools are just one way in which the $100 laptop could change the computer industry more broadly. By depressing prices and fuelling the trend for "good-enough computing", where customers upgrade less often, it could eventually put pressure on the world's biggest PC-makers.
According to the text, which of the following is beyond the public's anticipation？
A．The idea of cheap trick is starting to come true.
B．OLPC is able to create so inexpensive laptops.
C．Every secondary-school student will purchase a $100 laptop.
D．Sales to schools are just one way to display the first prototype.

听力原文： Good morning, everybody.Now I'm going to tell you how to buy a ticket for the BA
听力原文： Good morning, everybody. Now I'm going to tell you how to buy a ticket for the BART system.
Each person must have a ticket. Children aged not more than four do not need a ticket. Since each of you has a brochure in hand, you may first check the fare chart on the facing page for your destination and cost of your trip. Fare charts show the cost of a one-way trip, multiply by two for a round trip. Then go to a ticket machine and purchase your ticket. Some machines provide change. Others do not. Signs on the machines indicate which ones give change. No machines will give you more than $4.95 in change. Ticket machines will accept nickels, dimes, quarters, $1, $5, $10, and $20 bills. (Note: if your bill is not accepted, turn it upside down and try again.) Machines sell tickets for any amount from a minimum of $1 to a maximum of $40, so you can purchase a ticket good for several rides. Lastly, take your ticket and insert it in the fare gate. The ticket will be returned to you. You must use the same ticket when exiting at your destination.
Again, change machines for coins and $1 bills are located in all stations. You can add value to your ticket up to a maximum new total of $40 if there is $7.95 or less remaining. Put the ticket in the "old ticket" slot and add at least 5 cents or more. You will then get a new ticket combining the old value and the added money.
What kind of people don't need a ticket？
A．A group of 4 children.
B．Children not more than 4 years old.
C．Those who ride every day.
D．Those who are free from work.
