"I realized that I would not move upin my career without a degree. "A generation ago, Jonaitis would have beena rarity(稀罕)incollege. Today about 6 million people aged25 or older are studying in Americaninstitutions of higher learning. Whether they are returning to improve jobskills or for the love of learning, adults no longer see age as a deterrent(障碍).Most people jump at the oppor- tunity to do something new. Some ofthem make changes they' d been thinking about all their lives. Others re- turnto school out of economic necessity.New developments in neuroscience(神经科学)and psychology areconfiring that there are few age limits on how much the brain can absorb and for how long--if you stay active.Continuing to learn keeps us mentally inshapeand able to learn more. On mental tests, experts discovered, half to two-thirdsof the people in their 70s were as intellectually quick as people in their 30s.Those who fell below average tended to be people who had not made a lifelonghabit of reading. They also were less physically active.Many adult students say learning is easierfor them today. They bring different skills to the classroom, andthey' reless upset if something goes wrong. They have a real thirst, a real desire tolearn.{TS}A life-long habit of reading and physicalactvifies can keep_________________in good condition.A. our mindB. our bodyC. our ageD. our nerves(2)Learning is easier for adult students because_________________A. they do not learn in classroomsB. they have a real desire to learnC. they learn a lot from their own mistakesD. they aremore worried about their learning than the younger students(3)Thebest title for the passage is _________________.A.

Such an imbalance exists when the total valueof a country's imports ex- ceeds that of its exports. For example, if a countrybuys $ 250 billion of products from other countries, yet sells only $ 100billion of its own products overseas, its trade deficit is $ 150 billion. Manyunderdeveloped nations find themselves in this position because they lacknatural resources or the industrial capacity to use these resources, and thushave to import raw materials or manufactured goods.One effect of a trade deficit is the flowof currency (货币)out of a country. In the case of an underdeveloped nation, this cancause many financial difficulties, including failure to meet debt payments andobstacles to creation of an industrial base. Even in the case of a fullydeveloped nation such as the United States, a large tradedeficit is reason for alarm. American products, made by well-paid workers in USindustries, cost more to produce than those made in places like Asia, wherelabor and material costs are much lower. Money spent on foreign products ismoney not spent on items produced by domestic industries.{TS}Whatis the passage mainly about?A. Several worldwide economic problems.B. The causes and consequences of tradedeficit.C. Lack of resources in underdevelopedcountries.D. The value of exports against imports.(7)According to the passage, when does a trade imbalance occur?A. When a country has serious economic problem.B. When a country sells more products overseas thanit imports.C. When the value of the products a country importsis greater than the value of the product itexports.D. Whena country can't develop its natural resources.(8)Theword "deficit" (Line 4, Para. 1)would be best replaced by which ofthe following?A. shortageB. situationC. increaseD. products(9)Which of the following is NOT mentioned as a possible cause of a tradeimbalance?A. Low labor and material costs in Asiancountries.B. A lack of natural resourcesC. An underdeveloped industrial base.D. The high cost of exported items.(10)It can be inferred from the passage that American industries _________________A. do not pay their workers sufficient wagesB. are hurt by a trade imbalanceC. import labor and materials from overseasD. provide a strong industrial base that prevents atrade deficitReading Comprehension(40minutes) Section C D E(1)回答{TSE}题：Would you know how to help?Every year. thousands of drivers andpassengers die in the few minutes after an auto collision.

Exercise 2Question 2. Computer PurchaseLet us assume that you are purchasing a new computer for a specific usage. You need to choose a computer from various available configurations.Listed below are four different usage cases of a computer (a-d). For each usage case, identify components of the computer configuration that are most important to consider. Explain your answers.Components to be considered include (but are not limited to): ∙Monitor size/resolution∙Graphics card/video card∙Storage devices (for example, DVD-ROM)∙Memory (RAM, cache, and hard disk)∙Disk controller interfaces (ATA, EIDE)For example, if a computer were to be used for viewing movies, a DVD-ROM drive is needed since movies are available as CDs and now increasingly as DVDs. A l arge monitor (about 19”) that supports high resolutions and a video card will also be necessary to enjoy the movie.a. Simultaneously running a number of programsLarge capacity memory (at least 1G ) is needed to stores data and instructions needed to execute programs when a number of programs run. In order to resolve this question, we should select the appropriate processor.T he Intel® Core™ Duo processor with its two execution cores is optimized formulti-threaded applications and multitasking. You can simultaneously run multiple demanding applications, such as 3-D games or serious scientific research programs, while downloading files or runningvirus-scanning security programs in the background.b. Running a speed-critical applicationConsidering system running speed: AMD processor is typically with less cost, sometimes even faster than Intel's products.So the AMD Opteron™ processor is needed. The AMD Opteron processors with Direct Connect Architecture and HyperTransport™ Technology deliver leading-edge 32-bit performance today and enable you to transition to 64-bit computing at your own pace, without sacrificing your x86 technology investment.A mother board with high speed front side bus is neededc. Storing and retrieving huge volumes of dataA large storage hard disk is needed (at least 800G) to store huge volumes of data, at the same time, we should foresee the demand of it.A DVD-RW is needed when you want to store your huge volumes of data in DVD-ROM.A motherboard with EIDE interface can accommodate a total of four devices, maybe you will get up to2 hard disk or more.d. Purchasing a basic configuration, to be upgraded later as neededFor upgrading your system, you must set your system has ability of upgrade and extended. So one good motherboard is needed.The Intel® Desktop Board D975XBX is designed to deliver the best experience for advance d gamers and power-users. Based on the Intel® 975X Express Chipset and Intel® Pentium® processor Extreme Edition, this board has the best performance and the ability of upgraded. The Intel® Desktop BoardD975XBX supports Intel® Viiv™ technology, and comes with the software required to help meet Intel®Viiv™ technology brand verification requirements.Question 3. Laptop Computer SelectionYou are a new graduate student enrolling in a Masters in Information Technology program. The department requires you to have a computer with the following requirements:∙512 MB of RAM∙20 GB hard drive∙CD-ROM drive∙Wireless connection∙Ethernet network card∙Windows XP Professional versionYour school has wireless connection, and Ethernet jacks. However, some classes are three hours long, and your AC adapter may not be long enough to reach an outlet. You also would be carrying this computer around from class to class.The most you can spend is US$1200.Indicate the range of values you desire for each of the following criteria: a. Weightb. Screen sizec. Number of USB portsd. Number of Firewire portse. Need CD-RW?f. Need DVD-ROM?g. Need DVD-RW?h. Manufacturer preferences?i. Search the Internet for two suitable computers meeting the above requirements and your budget constraint. Submit screenshots of the Web pages detailing the computer configuration and price.j. Record your search results in a MS Excel spreadsheet. Fill column A with the following category labels:1. Manufacturer2. Processor3. Memory (maximum upgrade capacity)4. Screen size5. Weight6. Graphics card7. USB8. Firewire9. CD-ROM10. DVD-ROM11. Communications (e.g. wireless, Ethernet)12. Battery life13. Price14. Available RebateSave and submit your Excel file.k. Make your final purchase decision and justify your decision.Unit 1 and Unit 2 Review Materials2. Binarya.Define bit.b.Define byte.c.Fill in the following chart, listing the prefixes used forthe amount of bytes shown:d.Fill in the following chart, converting binary numbers todecimal and decimal numbers to binary:(Note:The numbers that appear in the table below will differon an exam from the numbers that appear on the exam's review sheet.)e.Although in sales literature 1000 bytes and 1024 bytes areboth commonly referred to as a kilobyte, in computing the only correct number of bytes in a kilobyte is1024. Explain why 1024 is correct. Many quantities in binary computers are restricted to powers of 2, and 210 is 1024, which is so close to 1000 that kilo is used informally.f.How can the difference in measuring bytes presented in parte impact a consumer when they are purchasing a hard disk drive?A hard disk drive is typically measured traditionally, in powers of 10. Thereforea gigabyte in a hard disk is 109, not the larger 230. Not knowing this, aconsumer might be surprised that the disk capacity was less than he thought was advertised.3.

I/Oa.Define I/O device. An I/O device, or input/output device, provides the userwith ways of giving the processor data to process and ways of receivingprocessed datab.Consider that a computer requires I/O devices to be able tointeract with its environment. Explain why it is necessaryfor computers to have these devices. The basic definition of acomputer includes input and output. These devices are necessary for thecomputer to exist. Differing I/O devices allow alternate input and output, butminimally the computer needs at least one of eachc.Give four examples of I/O devices. [Choose from] Keyboard; monitor;tape backup drive; scanner; microphone; speakers; CD writer; …d.For each I/O device in your answer to part c, explain thedevice's function from the perspective of a user.i.A keyboard provides data to a computer, to direct its behavior or supplyinformation for processing (name, address telephone number).ii.A monitor displays to the user the status and results of work performed by the computer.iii.A tape backup drive receives a copy of information stored on hard disk drives, and can later supply information to be stored on that hard disk drivein case the disk drive crashes or a file is accidentally deleted.iv.A scanner translates a picture or document to a bitmap image that can be processed by a computer, or included in other work like a web page orWord documentv.A microphone translates speech or music into digital from that can be processed by the computer.12. Picture Qualitya.Explain resolution, with respect to a monitor.Number of pixels on the screenb.List two typical monitor resolutions.1024x768, as an example.640x480, as an example.c.Explain color depth, with respect to a monitor.Maximum number of colors on the screen at one time.d.List two typical monitor color depths.16 bit, as an example.24 bit, as an example.e.Consider that the higher the resolution and the higher thecolor depth, the more system resources are required todisplay output on the monitor.e the resolutions from part b and the color depthsfrom part d to calculate the amount of RAM required todisplay the image. 1024x768x24/8=2.25MB, as an example.ii.Explain the calculation you made in part e.i in a waythat confirms the statement made at the beginning ofpart e—that "the higher the resolution and the higherthe color depth, the more system resources are requiredto display output on the monitor." The calculations in partE.i demonstrate that by increasing either the resolution or the color depththat the amount of memory required will increase, demonstrating thatmore system resources (RAM) are required.13.
