economy growth rate is______.
【正确答案】
B
【答案解析】 [听力原文] 7-8 Host: At Friday's annual meeting
of the American Economic Association in Washington, a panel of prominent
economists examined the business outlook and concluded that U.S. productivity
growth will slow and that the economy itself is unlikely to regain the fast
growth rates of the 1990s. Harvard University professor Dale
Jorgenson said, with the collapse of the high-tech bubble in the stock market,
the U.S. economy is reverting to the slower growth rates of the period 1973 to
1995. In the boom years from 1995 to 2000, the U.S. economy grew by about five
percent annually. That high growth. said Professor Jorgenson, was fueled by
enormous gains in productivity that are unlikely to return. Voice: So, 2.78 is the figure going forward for about the
next decade. In other words, we're not going to have an acceleration of economic
growth, contrary to what Alan Greenspan (central bank governor) may say in his
testimony to the Senate Banking Committee only two weeks from today. That's not
going to happen. It is something that it is just totally outside the range of
possibilities, even under the most optimistic assumption about productivity and
capital deepening.
