问题     The human brain contains 10 thousand million cells and
each of these may have a thousand connections. So enormous                  S1.______
numbers used to discourage us and causing us to dismiss the                 S2.______
possibility of making a machine with human-like ability, but now
that we have grown used to move forward at such a pace we can               S3.______
be less sure. Quite soon, in only 10 or 20 years perhaps, we will
be able to assemble a machine as complex as the human brain,
and if We can we will. It may then take us a long time to render
it intelligently by loading in the right software or by altering the        S4.______
architecture but that too will happen. I think it certain that in
decades, no centuries, machines of silicon will arise first to rival        S5.______
and then exceed their human ancestors. Once they exceed us they will
be capable of their own design. In real sense they will                     S6.______
be able to reproduce themselves.  Silicon will have ended
carbon’s long control. And we will no longer be able to claim
ourselves to be the fine intelligence in the known universe. As             S7.______
the intelligence of robots increase to match that of humans and             S8.______
as their cost declines through economies of scale that we may use           S9.______
them to expand our frontiers, first on earth through their ability
to withstand environments, beneficial to ourselves. Thus, deserts           S10.______
may bloom and the ocean beds be mined. Further ahead, by
a combination of the great wealth this new age will bring and the
technology it will provide, the construction of a vast, man-created
world in space, home to thousands or millions of people,
will be within our power.

选项

答案So→Such

解析 文章第一句为由and连接的并列句。第二个分句中,主语为each,指众多细胞中的一个;谓语have因为前面有情态动词may而保持原形;宾语connections为复数,故正确;enormous修饰numbers,也没问题,因此本行错误锁定在so上。名词前有形容词时,so和such都可以被用采修饰,但要注意不定冠词/an的位置,如so big a city/such a big city;如果修饰对象是复数或不可数名词时,则只能用such来修饰,故将So改为Such。
