一、高中英语阅读理解1．阅读理解It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be. He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft."If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things," said Ioannou.These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.（1）Which of the following statements about the newly created transistor is TRUE?A.They are expected to be used in high-resolution displays.B.The transistors are made with the element silicon.C.They are rigid, just like traditional transistors.D.They have already been put into actual use.（2）What does the underlined sentence in Paragraph 5 mean?A.The traditional transistors have been changed into two-dimensional ones.B.Many of the traditional transistors have been improved over the years.C.The traditional transistor has been developed to its fullest.D.The traditional transistor has been developed quite well.（3）What is Dimitris Ioannou's attitude towards the creation of the new transistors?A.Negative.B.Neutral.C.Indifferent.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“Scientists hope these new 2D transistors will be used for building high-resolution（高分辨率）displays that need very little energy.”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Dimitris Ioannou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。

2．阅读理解According to a team of researchers, an animal's ability to perceive(感知)time is linked to their pace of life."Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures." commented lead author Kevin Healy from Trinity College Dublin.The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve, "which allows them to avoid being hit.Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."In comparison, the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.（1）What is the research mentioned in the passage mainly about？A. Pace of life of animals.B. Impressive abilities of animals.C. Lifetime of small animals.D. Time perception of animals.（2）What does Kevin Healy's comment mean in Para.2？A. The survival of fast moving animals relies on their ability to perceive time.B. Animals with quicker pace of life have better perception of time.C. The ability of animals to perceive time depends on their high moving speed.D. Animals with poor ability of time perception have a shorter life.（3）Why can houseflies avoid being hit?A. They can think very deeply before they act.B. They can process the information as quickly as they receive it.C. They can fly much faster than their eyes can keep up.D. They can send information to brain more quickly than to their eyes.（4）What will a tiger beetle have to do to catch a moving prey?A. Slow down to gain its time perception.B. Prevent itself from becoming blind.C. Stop occasionally to spot the prey again.D. Try to run as fast as it can.【答案】（1）D（2）A（3）B（4）C【解析】【分析】本文是一篇说明文，介绍了对动物时间感知的研究。
