[不定项选择题]共用题干
第一篇
Rising College Selectivity
Rising college selectivity doesn't mean that students are smarter and more serious than in the past.It's a function of excess demand for higher education,occurring at a time of increased financial privatization of the industry.
The recession has only increased demand.The vast majority of students aren't going to college because of a thirst for knowledge.They're there because they need a job,and they need to get the credentials(证书)and one hopes, the knowledge and skills behind the credentials一that will get them into the labor market.
As higher education has become a seller's market,the institutions in a position to do so are doing what comes naturally:raising their tuitions and their admissions requirements,but at the expense of contributing to the national goal to increase college attainment.The result is that the United States is losing ground in the international race for educational talent.
The increasing stratification(阶层化)of higher education is happening on the spending side, as well.As the selective institutions have become more expensive and less attainable,the rest have had to struggle with the responsibility to enroll more students without being paid to do so.Gaps be-tween rich and poor have grown even more dramatically than gaps in entering test scores.While spending is a poor measure of educational quality,we can't seriously expect to increase educational attainment if we're not prepared to do something to address these growing inequities in funding.
That said,the educational policy problem in our country is not that the elite institutions are becoming more selective.The problem is on the public policy side.The president and many governors have set a goal to return America to a position of international leadership in educational attainment.
It's the right goal,we just need a financing strategy to get there.That doesn't mean just more money,although some more money will be needed.It also means better attention to effectiveness and to efficiency,and to making sure that spending goes to the places that will make a difference in educational attainment.We know how to do it,if we want to.
Since higher education has become a seller's market,the national goal to increase college attainment________.
A.will be fulfilled in a short time
B.will be difficult to achieve
C.will draw more public concern
D.will demand more financial input

[单项选择]I always have a difficult time choosing original birthday presents. My imagination never seems to get beyond ties, handkerchiefs, or pairs of socks. But, strangely enough, it did not take me long to decide on Tom’s birthday present. For the first time in my life I had a good idea—I would buy him a bottle of champagne. Before the party began, Tom suggested that I should open the bottle. I put it between my knees and began to pull, but it remained firmly corked.

I could hear all sorts of" helpful" suggestions from the guests like "Break the top off", "Use your teeth!" etc. But I was losing the bottle. We were struggling on the floor together, when all of a sudden there was a loud "pop!" and the cork shot up into the air, while the angry bottle showered everybody with champagne!
