UNIT 1 Learning does not happen passively. It is an activity which a person does.
It is a task which can be attempted in various of ways, some of which are 1._____
more appropriate than others. When the material to be learned is 2._____
a brief and simple kind which is familiar with the person and of intense 3._____
interest to him, effective learning usually proceeds automatically.
In the first place, the person at once relates the material to other
material which has already securely learned. Subsequently, the relevance 4._____
of the newly learned material to his interests assures its being 5.______
recalled on many occasions; and one repetition minimizes 6.______
the likelihood of remembering. Furthermore, the subsequent use 7.______
of the new material is likely to take place in a variety of contexts
and, so, the material becomes related to a narrower range of other material. 8.___
Because of&nb sp;all this, the material is rapidly learned, long retained,
and recalled with increasingly readiness in a variety of 9._____
contexts. Without really trying, the person had fulfilled a 10._____
few important conditions of effective learning.

Almost every new innovation goes through three phases.
When initially introducing into the market, the process 1._____
of adoption is slow. The early models are expensive and
hard to use, and perhaps even unsafe. The economic
impact is relatively great. 2. _____
The second phase is the explosive one, where the innovation
was rapidly adopted by a large number of people. It gets 3. _____
cheaper and easier to use and becomes something familiar.
And then in the third stage, diffusion of the innovation
slows down again, as if it permeates out across the economy. 4. _____
During the explosive phase, whole new industries spring
up to produce the new product or innovation, and to service
it. For example, during the 1920s, there was dramatic 5. _____
acceleration in auto production, from 1.9 million in 1920
to 4.5 million in 1929. This boom was accompanied with all 6. _____
sorts of other essential activities necessary for an
auto-based nation: Roads had to been built for the cars to 7. _____
run on; refineries and oil wells, to provide the gasoline;
and garages, to repair it. 8. _____
Historically, the same pattern is repeated again and again
with innovations. The construction of the electrical system
requested an enormous early investment in generation and 9. _____
distribution capacity. The introduction of the radio was
followed by a buying spree (无节制的狂热行为) by Americans
what quickly brought radios into almost half of all households 10. _____
by 1930, up from nearly none in 1924.
