the rise.

Part of the attraction to the island is that tourists can buy imported goods there at duty-free prices.

e.g. Our client-intimate service contributes much to the growth of the company.

The GPS is designed in a user-intimate approach, and you can easily find your way just by a few

touches on its screen.

4. partner or associate in an activity or job

e.g. As the proud co- sponsor of the conference, we come not only to offer our support, but also

share our experience.

Penn, co-author of National Food And Agriculture Policy, has served for three years as a senior

economist at the United States Department of Agriculture.

years

ago,

when

our

company

was

at

the

height

of

its

production,

we

decided

to

invest in new technologies, so as to turn our company into a technology-intensive one. With our

advanced

marketplace. Now we have reduced the cost by 30 percent, even as / while our sales have grown

by two-thirds and the earnings have doubled.

我们将可持续性定义为保持企业盈利，

但不以环境为代价。

从 商业的角度看，

这合理吗？

可持

续发展的推进起到了如此重要的作用，帮助我们撑过了史上最深重的经济 衰退。

environment. Does this make good business sense? Actually, what we get has more than offset all

the

investments

expenses

development.
