D.Positive.

【答案】

（1）A

（2）C

（3）D

【解析】【分析】本文是一篇说明文，美国科学家发明了新的二维晶体管，介绍了新型二维晶体管的相关信息及未来前景。

（1）考查细节理解。

根据第二段中的“Scientistshopethesenew2Dtransistorswillbeusedforbuildinghigh-resolution（高分辨率）displaysthatneedverylittleenergy.”可知，科学家们希望能用这些新的二维晶体管来制造高分辨率的显示器。

故选A。

（2）考查句义猜测。

划线句句意为“他说传统的晶体管已经尽可能地改进了”可推知，传统的晶体管已经开发到了极致。

故选C。

（3）考查观点态度。

根据最后一段中的DimitrisIoannou所说的话可推知，他对于这种新型的晶体管持有积极乐观的态度。

故选D。

【点评】本题考点涉及细节理解，句义猜测和观点态度三个题型的考查，是一篇科技类阅读，考生需要准确捕捉细节信息，并根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。
