第5题:

Building a house costs quite a lot of money. Suppose you plan to build a house. Your first step will be to find a right piece of land. Your choice will depend on many different things. You will probably try to find a sunny place, with pleasant surroundings near shops and bus stops, not too far from your friends and the place where you work.
Next you will find a good builder, and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms, their position and size, and other parts, which must be noticed, such as windows, doors, and electric outlets. The builder will work out how much money is needed to build your house. He will work out the cost of the wood, bricks, the glass, and everything else that must be used in building the house. Later on, when he starts to build, this estimate must be corrected and revised. His estimate is based on existing prices, but prices of such things may change, and many other things may happen between the time when he makes the estimate and the time when he builds the house.
When the builder gives his estimate, you may wish to change your plan. (You may also wish to change your builder, if his estimate is too high! ) You may find that the house you wanted at first costs too much, or that you can spend a little more and add something to your plan. The builder's estimate depends on the plan, but the final plan depends on the builder's estimate.
What is the relationship between the estimate and the plan?

A.The plan depends on the estimate
B.The estimate depends on the plan
C.The plan has nothing to do with the estimate
D.The estimate and the plan depend on each other

答案:D
解析:
本题考查的仍是对短文个别段落和中心意思的理解。短文第三段集中讲的就是和建房方案之间的关系。A项只说出了建房方案对预算的依赖关系;B项只说出预算对建房方案的依赖关系,而忽略它们相互作用的一面,因此都是片面的。而c项说的是建房方案与预算毫不相干,这与短文交代的事实背道而驰.故予以排除。

第7题:

Your Windows 2000 Professional computer contains a single hard disk configured as a single partition.

You want to move a folder named Sales under a folder named Corp on your computer.

You want the files in the Sales folder to remain compressed after moving the folder. You want the files in the Corp folder to remain uncompressed. You want to ensure that the files are recoverable in case of any disk problems. You also want to move the files with the least amount of administrative effort.

What should you do?

A.Copy the Sales folder to the Corp folder. Do nothing further.

B.Backup the Sales folder. Move the Sales folder to the Corp folder.

C.Compress the Corp folder. Then copy the Sales folder to the Corp folder.

D.Move the Sales folder to a second computer. Then move the Sales folder to the Corp folder.


正确答案:B
解析:Explanation: The contents of the Sales folder should be backed up so that files would be recoverable in case of disk problems. You could move the Sales folder to the CORP folder, as the files will remain compressed since the folder is moved within a single partition. The general rules on copying and moving compressed files and folder are: files and folders copied within a NTFS volume and between NTFS volumes inherit the compression state of the target folder; files and folders moved between NTFS volumes inherit the compression state of the target folder; and files and folders moved within an NTFS volume retain the original compression state of the file or folder.

Incorrect Answers:
A: A folder copied within an NTFS partition will inherit the compression state of the target folder. This will result in the Sales folder inheriting the uncompressed state of the CORP folder since the target folder is uncompressed. Furthermore, you are also required to ensure that the folder contents are recoverable in the event of a system failure. This solution does not make provision for the recovery of the folder.

C: A folder copied within an NTFS partition will inherit the compression state of the target folder. This will result in the Sales folder losing its compressed state since the target folder is uncompressed. Compressing the CORP folder is also not a viable solution, as the scenario explicitly requires you to retain the uncompressed state of the files in the CORP folder. Furthermore, you are also required to ensure that the folder contents are recoverable in the event of a system failure. This solution does not make provision for the recovery of the folder.

D: Files and folders that are moved between NTFS partitions inherit the compression state of the target folder. Therefore the Sales folder might lose its compression state. Furthermore, moving the Sales folder twice is unnecessary as this will not ensure recoverability of the files in the Sales folder.
