Now that so much data travels via light--i.e., is carried in glass fibers rather than by electrical current--one goal of semiconductor research is to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead to smaller, faster semiconductors.
(A) to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead
(B) to develop a silicon chip with the capability of transmitting and receiving light signals directly, which may one day lead
(C) the development of a silicon chip that has the capability of transmitting and receiving light signals directly, a development maybe one day leading
(D) developing a silicon chip that can transmit and receive light signals directly, which may one day lead
(E) developing a silicon chip with the ability to transmit and receive light signals directly, with this
development maybe one day leading
key A
这道题的主语是谁?is carried in glass fibers rather than by electrical current 也没有主语阿?
i.e.是“即,就是”的意思
主语是goal ...句子主干是:
now that... a goal of ...is to do ...., a development(同位语接上)...
is carried in glass fibers rather than by electrical current是插入语,修饰的是data.
多谢aeoluseros~~
Now that so much data travels via light 是干啥的阿?now 在这里是引导句子的,这个句子里的主语是date, 谓语是travel,这样理解对吗?
还所有插入语怎么没有主语阿?感觉插入成分怪怪的
这个理解对的~
Now that so much data travels via light
既然/因为很多数据是通过光来传输的。now是连词,意思是“因为”,that可省可不省。
是挺特殊的,以前见到的插入语基本上是分词短语,介宾短语,或者主谓结构
i.e.是一个adv.可不看它
is carried in glass fibers rather than by electrical current这个插入语里,我想可能是把相同的主语省略了,也算是主谓结构的一种吧。
