[单项选择]President Bush has proposed adding optional personal accounts as one of the central elements of a major Social Security reform proposal. Although many details remain to be worked out, the proposal would allow individuals who choose to do so to divert part of the money they currently pay in Social Security taxes into individual investment accounts. Individuals would have a choice of fund managers, and the return that they earn from those accounts would then partially determine the Social Security benefit they receive when they retire.
Individual accounts pose a number of important and complex design and implementation issues, including how to lower the cost of administering accounts so that they do not erode the value of pensions that individuals receive when they retire, how many and what kinds of fund choices should be offered, and how to engage workers in choosing funds.
In the late 1990s, Sweden added a mandatory individual accounts tier to its public pension system. T

[单项选择]Reading 5 "Speech and Writing"
It is a widely held misconception that writing is more perfect than speech. To many people, writing somehow seems more correct and more stable, whereas speech can be careless, corrupted, and susceptible to change. Some people even go so far as to identify language with writing and to regard speech as a secondary form of language used imperfectly to approximate the ideals of the written language.
→ One of the basic assumptions of modern linguistics, however, is that speech is primary and writing is secondary. The most immediate manifestation of language is speech and not writing. Writing is simply the representation of speech in another physical medium. Spoken language encodes thought into a physically transmittable form, while writing, in turn, encodes spoken language into a physically preservable form. Writing is a two-stage process. All units of writing, whether letters or characters, are based on units of speech, i.e.,
A. To demonstrate that speech cannot be transcribed
B. To provide examples of two good writing styles
C. To prove that a nonstandard variety can be written
D. To contrast varieties of speech for their characters

[单项选择]
Happiness can be described as a positive mood and a pleasant state of mind. According to recent polls (民意测试) , sixty to seventy percent of Americans consider themselves to be moderately happy and one in twenty persons feel very unhappy. Psychologists have been studying the factors that contribute to happiness. It is not predictable nor is a person in an apparently ideal situation necessarily happy. The ideal situation may have little to do with his actual feelings.
A good education and income are usually considered necessary for happiness. Though both may contribute, they are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs.
The rich are not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly because they have more opportunity to c
A. Being exceptionally good-looking.
B. Having a good paying job.
C. Having a loving, affectionate relationship.
