4、Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), and D). you should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the center.
Passage One
Questionsare based on the following passage.
What should you think about in trying to find your career? You are probably better at some
school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think about what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools, perhaps you are a poor speller or cannot add up to a column of figures. It is better to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
Which of the following can best sum up the first paragraph?
A.The importance of doing well at school.
B.Using school performance to help to choose a career.
C.The importance of being good at all subjects.
D.The indirect value of school work.

7、Paper--More than Meets the Eye
We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades.
It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.
Paper can be made from an almost endless variety of cellulose-based material which will include many woods, cottons and grasses or which papyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.
Paper from Wood
In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence
of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.
A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it holds the cellulose fibres together, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives.
Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.
It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and is some cases simply vanish!
So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may
indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.
Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on,
the correct material then this is probably the only way.
Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.
Paper from Rag
Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to
purchase from a reliable source though, since even rag paper and card can contain undesirable additives.
A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and board.
The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.

9、回答题:
Can Digital Textbook Truly Replace the Print Kind?
  The shortcomings of traditional print edition textbooks are obvious: Forstarters they're heavy, with the average physics textbook weighing 3.6 pounds.They're also expensive, especially when you factor in the average collegestudent's limited budget, typically costing hundreds of dollars every semester.
  But the worst part is that print version of textbooks are constantlyundergoing revisions. Many professors require that their students use only thelatest versions in the classroom, essentially rendering older texts unusable.For students, it means they're basically stuck with a four pound paper-weightthat they can't sell back.
  Which is why digital textbooks, if they live up to their promise, couldhelp ease many of these shortcomings. But till now, they've been something likea mirage (幻影) in the distance,more like a hazy (模糊的) dream thanan actual reality. Imagine the promise: Carrying all your textbooks in a 1.3pound iPad? It sounds almost too good to be true.
  But there are a few pilot schools already making the transition (过度) over to digital books. Universities like Cornell and Brown havejumped onboard. And one medical program at the University of California,Irvine, gave their entire class iPads with which to download textbooks justlast year.
  But not all were eager to jump aboard.
  "People were tired of using the iPad textbook besides using it forreading," says Kalpit Shah, who will be going into his second year atlrvine's medical program this fall. "They weren't using it as a source ofcommunication because they couldn't read or write in it. So a third of thepeople in my program were using the iPad in class to take notes, the otherthird were using laptops and the last third were using paper and pencil."
  The reason it hasn't caught on yet, he tells me, is that thefunctionality of e-edition textbooks is incredibly limited, and some studentsjust aren't motivated to learn new study behavior.
  But a new application called Inkling might change all that. The companyjust released an updated version last week, and it'll be utilized in over 50undergraduate and graduate classrooms this coming school year.
  Digital textbooks are not going to catch on," says Inkling CEO MattMaclnnis as he's giving me a demo (演示) over coffee. "What I mean by that is the current perspectiveof the digital textbook is it's an exact copy of the print book. There's CourseSmart, etc., these guys who take any image of the page and put it on a screen.If that's how we're defining digital textbooks, there's no hope of that becominga mainstream product."
  He calls Inkling a platform for publishers to build rich multimediacontent from the ground up, with a heavy emphasis on real-world functionality.The traditional textbook merely serves as a skeleton.
  At first glance Inkling is an impressive experience. After swiping (敲击) into the iPad app (软件), which youcan get for free here, he opens up a few different types of textbooks.
  Up first is a chemistry book. The boot time is pretty fast, and henavigates through (浏览) a fewchapters before swiping into a fully rendered 3D molecule that can be spunaround to view its various building blocks. "Publishers give us all of thesource media, artwork, videos," he says, "We help them think throughhow to actually build something for this platform."
  Next he pulls up a music composition textbook, complete with playabledemos. It's a learning experience that attacks you from multiple sensorydirections. It's clear why this would be something a music major would love.
  But the most exciting part about Inkling, to me, is its notation (批注) system. Here's how it works!
  When you purchase a used print book, it comes with its previous owner'shighlights and notes in the margins. It uses the experience of someone whoalready went through the class to help improve your reading (how much you trusteach notation is obviously up to you).
  But with lnkling, you can highlight a piece of content and make notes.Here's where things get interesting, though: If a particularly importantpassage is highlighted by multiple lnkling users, that infbrmation is stored onthe cloud and is available for anyone reading the same textbook to come across.Thai means users have access to notes from not only their classmates andFacebook friends, but anyone who purchased the book across the country. Thebest comments are then sorted democratically by a voting system, meaning thatyour social learning experience is shared with the best and brightest thinkers.
  As a bonus, professors can even chime in (插话) on discussions. They'll be able to answer the questions ofstudents who are in their class directly via the interactive book.
  Of course, Inkling addresses several of the other shortcomings intraditional print as well. Textbook versions are constanly updated, motivatingpublishers by minimizing production costs (the big ones like McGraw-Hill arealready onboard). Furthermore, students will be able to purchase sections ofthe text instead of buying the whole thing, with individual chapters costing aslittle as $2.99,
  There are, however, challenges.
  "It takes efforts to build each book," Maclnnis tells me. Andit's clear why,
  Each interactive textbook is a media-heavy experience built from theground up, and you can tell that it takes a respectable amount of manpower toput together each one.
  For now the app is also iPad-exclusive, and though a few of theseeducational institutions are giving the hardware away for free, for otherstudents who don't have such a luxury it's an added layer of cost ---and anexpensive one at that.
  But this much is clear. The traditional textbook model is and has beenbroken for quite some time. Whether digitally interactive ones like Inklingactually take off or not remains to be seen, and we probably won't have adefinite answer for the next few years.
  However the solution to any problem begins with a step in a direction.And at least for now, that hazy mirage in the distance? A little more tangible(可触摸的), a little less of a dream.
The biggest problem with traditional print textbooks is that
A.they are not reused once a new edition comes out
B.they cost hundreds of dollars every semester
C.they are too heavy to carry around
D.they take a longer time to revise
