159. 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 mav one dav 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

 问题：sth can do 逻辑上没有问题么？

A: correct

B: with the capability of不如从句；which没有指代

C: one day leading 不能表达出未来的含义

D: which没有指代

E: 同上

 

注意：

1、介词+ doing结构和从句结构比较，从句的有效性

2、需要表达时间的概念要用从句而不是分词

牛刀杀小

MM要问的是这个意思吗？有太多的sth that can...的例子了
