问题 As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased.
选项 A、the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
B、the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
C、the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
D、their circuits are more complex, the power of both the chips and the electronic devices they drive have
E、their circuits more complex, both the power of the chips and the electronic devices they drive have
答案B
解析 由于thinner和more complex的对应，表明了circuit之后省了与前半句相同的havebecome，因此C、D错；D、E中：their从句法上讲优先指代lines而不是lines修饰语中的chips，属指代不清；A、C、E中的both the power of the chips and the electronic device they drive这种表达很容易让人认为是the power of the chips和the electronic device they drive两者之间的并列，这样并列不仅不合逻辑，且原句显然也不是此意，而是the power of both the chips and the devices，B表明了此意，并把have换为has，主谓一致。
