1.When today's high-school seniors are asked what they plan to do

after graduation, most say that they intend to get bachelor's degree.

They have been told that their generation has only" one way to win" -by

getting at least a bachelor's degree, in the hope that it will eventuallv

lead to a professional job.

In a recent survey of high-school seniors conducted by the National

Center for Education Statistics, 85per cent of the respondents said they

planned to get bachelor's degree. And，although 20years ago only 45

per cent of high-school graduates went on to college, today 68 per cent

actually matriculate (注册)， with the majority enrolling in four-γear or

two-year programs designed to allow them to transfer to four-year

institutions.

According to conventional wisdom, the rapid rise in the number of

students attending college is cause for national celebration. But our

research suggests that，instead it may be cause for national concern.

Why? because for many young people, the "one way to win" paradigm（例子)is not realistic ,given their academic talents and the

labor-market projections. Students ranking below the top third of their

high-school graduating class too often fail to earn a bachelor's degree if

they enroll in college. The cost of such failure--in both dollars and

unmet expections-is rising and beginníng to erode public confidence in

our system of higher eduation.

2. A small family-owned company, Eisai, was one of the original

manufacturers of vitamin E, and it maintained a strong research

commitment to

natural pharmaceuticals. Over the years, it developed

drugs for the treatment of cardiovascular, respiratory, and neurological

diseases. The company

experienced steady. Modest growth, and in

1992 sales reached 197 billion yen and profits

approached 13 billion

yen. Although it was the sixth-largest Japanese pharmaceutical

company . Eisai was a

relatively small player in an industry in which

global competition was increasing while growth in the domestic market

was slowing down.

In 1993, Haruo Naito took over as president from his father. Before

that, he had

chaired Eisai's five-year strategic planning committee.

During that time, he had become convinced that the company's focus

on the discovery and manufacture of pharmaceuticals was not

sustainable for long-term growth against large, global competitors.

Two years after becoming president, Naito formulated a radical new

vision for Eisai that he called Human Health Care. It

extended the

company's focus from manufacturing drug treatments or specific illness

to improving the overall quality of life. To accomplish that mission. Eisai

developed a wide

array of new products. And that, In turn, would

require broad involvement and commitment. He encouraged innovative

activity and created an environment in which employees' efforts would

be accepted and

rewarded. Soon there were

proposals for 130

additional HHC projects and by the end of 1996. 73 projects were under

way. Now, the company has moved from sixth to fifth place in the

Japanese domestic pharmaceutical industry, and Eisai's customers and

competitors view the company as a leader in health care.

3. Today it can be said that wheels run America. The four

rubber tires of the automobile (move) America through work and pay.

Wheels spin, and people (drive) off to their jobs. Tires turn, and people

shop for the week's food at the big supermarket (down) the highway.

Hubcaps whirl, and the whole family spends a day at the lake .Each year

more (wheels) crowd the highways a 10million new cars roll out of the

factories. One (out) of every six Americans works at assembling cars.

Driving trucks, building roads, or pumping gas, America (without) cars?

It 's unthinkable.

But even though the (majority) of Americans would find it hard to

(imagine) what life would be like without a car , some have begun to

(realize) that the automobile is a mixed blessing. Traffic accidents are

increasing steadily, and large cities are (plagued) by traffic congestion,

Worst of all, perhaps, is the air pollution caused by the

internal-combustion engine. Every car engine (burns) hundreds of

gallons of fuel each year and pumps hundreds of pounds of carbon

monoxide and other gases into the air. These gases are one source of

the smog (that) hangs over large cities. Some of these gases are

poisonous and dangerous (to) one's health, especially for someone with

a weak heart or a respiratory disease.

One answer to the problem of air pollution is to build

a car that does not pollute. That's (what) several major automobile

manufacturers are crying to do. (But) building a clean car is easier said

than (done). S0 far, progress has been slow. Another solution is to

eliminate car fume (altogether) by getting rid of the

internal-combustion engine. Inventors are now working on
