[2019·贵阳市期末检测]You try to keep your eyes wide open while watching a basketball match or a wonderful firework show in case you might miss something exciting in just the blink of an eye. But in fact, humans blink about 15 times per minute on average. Have you ever missed anything because you blinked? Probably not. Why is that?
According to a new study published in the journal Current Biology in September, our brain has the ability to skip the temporary darkness when we blink. It can keep visual information for a short period of time and then put it together to form an image without interruption.
In order to understand how this works, a group of scientists at the German Primate Center and the University Medical Center G?ttingen in Germany conducted an experiment. In the study, the participants were asked to look at patterns on a screen whose direction could be interpreted in different ways, such as horizontally(水平地) or vertically(垂直地). When one pattern was about to disappear and the next one was about to come, the participants had to indicate the direction that the next pattern would appear.
The researchers found that when the directions of two patterns didn't match, the area in our brain which is responsible for visual memory was activated. This same area showed less activity when two patterns were in the same direction.
“The medial prefrontal cortex (额叶皮层) adjusts current visual information with previously obtained information, and thus enables us to perceive the world with more stability, even when we briefly close our eyes to blink，” Caspar Schwiedrzik explained in Science Daily. He is the first author of the study and also a scientist at the German Primate Center.
1．We don't miss anything when blinking because our brain can ________. A．deal with the missing image B．remember all that we see C．imagine what our eyes miss D．put our pieces of memory together
2．What does the underlined word “it\\” in Paragraph 2 refer to?
- 1 -
A．Our brain. B．Visual information. C．Current Biology. D．The temporary darkness. 3．What do we know about the experiment? A．The two patterns appear at the same time.
B．Visual memory can be more activated by similarity. C．Participants can interpret patterns differently. D．The different directions activated visual memory. 4．What would be the best title for this passage? A．The Brain's Structure
B．The Brain's Activated Patterns C．The Brain's Special Skill D．The Brain's Orientation

[2020·沈阳市高三教学质量监测(三)]Bikes were invented when people felt the need for stable, fast and efficient vehicles. The idea of making a bike started in the 1790s. It was inspired by a toy.
In 1792, it started off as a two－wheeled part attached to a rigid wooden frame. People would use their feet to move the bike. However, it wasn't really what people were looking for with a lot of faults. It was a kind of transport highly demanding human energy, and the other problem was the poor stability. The front wheel could not turn so one had to get off the bike to turn it. Therefore，there was a need for it to be improved, but it was not the same person who created it that changed it.
In 1820 the bike yet again had a new twist. Not only could the front wheel turn，but it was made more comfortable as a back supporter was secured. But one still had to move it by pushing it by feet on the ground. If one wanted to ride this bike, which was called a “hobby horse\\” at that time, he should know how to keep his balance. The other impressive thing that had changed was the speed，which increased up to 15 kilometers per hour.
Ten years later, there came the bike popular even today. This was invented by a blacksmith who used the idea of a pivot(枢轴) to develop the bike. It did not stop there. People were never satisfied with it because times also did change. As other things were being improved, so were the bikes.
Now with everything in place, there is a need to improve on the speed of these bikes. And the idea of it being only human-powered is out of date. Today bikes have

been improved and remodeled but the resemblance to the original bikes is still there.
5．What was one of the problems with the first bicycle? A．It was regarded as a toy. B．It had too many wheels.
C．It had to be operated with efforts. D．It was too stable to turn the wheel.
6．What can we know about the bike from the text? A．The bike popular with us today appeared in about 1830.
B．The bike was invented and improved by the same person. C．The bike made in 1820 had to be moved forward by hand. D．The bike was called a “hobby horse\\” when it first appeared. 7．What remains similar in modern bikes compared with those in history? A．The structure. B．The speed. C．The safety. D．The weight.
8．Which of the following can be the best title for the text? A．The Development of Bikes B．The Invention of Bikes C．The Impressions on Bikes D．The Problems with Bikes Ⅱ.完形填空

[2020·福建三校联考]One year ago, I was in great trouble. I worked hard at English and devote all my spare time to practise it. But I failed to pass the mid-term examination, which made me great disappointed. So I asked my grandpa for advice when I got to home. Hearing that I told him, he said, “To some extent examination results sometime cannot reflect your study level. You can't judge your progress by one examination.” He encouraged myself to work hard for long time to check my results. I took my grandpa's advices. Now I realize that the process of learning is much more important and my English is much good than before. From my experience, I feel that we should listen to opinions from old people.
