Why Do People Blink Their Eyes?
People blink(眨眼) their eyes tens of thousands of times every day. Scientists have long believed blinking was a natural movement and served mainly to keep the eyeballs wet. But a new study suggests it has a more important purpose.
An international team of scientists from the University of California studied the blinking of human eyelids. The journal Current Biology published their findings. The team said they found that blinking “repositions our eyeballs so we can stay focused” on what we are seeing. They said that when we blink our eyelids, the eyes roll back into their sockets(眼窝). However, the researchers found the eyes don’t always return to the same position. They said this causes the brain to tell the eye muscles to reorganize our eyesight.
Gerrit Maus , an assistant professor of psychology at a Technological University, said, “Our eye muscles are quite sluggish(迟缓的) and unclear, so the brain needs to repeatedly adapt（适应于） its motor signals to make sure our eyes are pointing where they’re supposed to. Our findings suggested that the brain measures the difference in what we see before and after a blink, and commands（指挥） the eye muscles to make the needed corrections.” The researchers said that without such corrections our surroundings would appear unclear and even jumpy.
The researchers said they asked volunteers to sit in a dark room while staring at a small dot on a flat surface. They used special cameras to follow the volunteer’s blinks and eye

movements. After each blink, the dot was moved one centimeter to the right. The volunteers did not notice this, but the brain did. It followed the movement and directed the eye muscles to refocus on the dot. After the dot was moved in this way 30 times, the volunteers’ eyes changed their focus to the place where they predicted it would be.
Professor Maus said, “Even though participants did not consciously（自觉地） register that the dot had moved, their brains did, and adjusted with the corrective eye movements. These findings add to our understanding of how the brain constantly adapts to changes, commanding our eye muscles to correct for errors in our bodies’ own hardware.” 27. According to the new study, blinking eyes can ______.
A. reposition eyeballs to stay focused B. consciously correct eye movements C. make our eyes adapt to motor signals D. serve to keep the eyeballs wet
28. The underlined word “register” in Paragraph 5 probably means ______. A. realize B. review C. remind D. reason 29. This passage shows that ______.
A. eye muscles are quite inactive and unclear B. the research is of great value in the eye movement C. the brain plays an important role in seeing things clearly
D. volunteers control their blinks to follow the changes of the dots

Do you find that it’s hard to look at your phone without getting discouraging looks from teachers and parents? What if using social media was an assignment（作业）?
In America, the push for more technological classrooms comes from things like smart boards and online textbooks. Some feel that interaction between students and teachers over social media is a bad thing, but others see the benefits. Barrington history teacher Robert Seidel uses the social networking website Twitter to interact with his class. He said technology is a valuable tool in his classroom.
“What matters most is how the teacher is using technology, and I have found that technology can help me increase the number of students who actively participate in my course,” said Seidel.
Humanities and media teacher Scott Glass from Glenbrook South High School in Illinois believes that social media like Twitter can connect students to the professional world and give them a chance to get their names out there as soon as they can.

“I think students are sometimes surprised by how easy it is to connect with professionals,” Glass said. “A simple Google search for any profession will turn up many individuals and organizations who are active on platforms like Twitter.”
However, there are problems with putting class work on social platforms (平台). Many teachers, including Seidel, believe that social media and technology in general can easily distract(使分心) students. However, they hope they can find a way to use it properly.
“For teachers and students, technology has become both a powerful tool for learning and a potential distraction in the classroom,” Seidel said. “Not only can it improve collaboration, communication and creation in endless ways, but it can also serve as an infinite（极大的） distraction. Properly using technology in the classroom requires additional management from the teacher as well as a great deal of self-discipline (自律) from the students.”
Glass believes it’s very important for schools to teach students how to use social media. “As a teacher, I think part of my job is to help students understand how best to make use of it as thoughtful learners and creators,” said Glass.
30. By using social media, ______.
A. it will be easier for teachers to observe students’ performance B. students will become more actively involved in courses C. students will become independent learners D. fewer students will attend the class
31. According to the passage, Glass probably believes that social media ______. A. is a good platform for students to share their class work B. can help students to contact professionals more easily C. offers students the latest knowledge in real world D. makes it much easier for students to get jobs
32. Which of the following is TRUE according to the passage?
A. Social media should not be used in the classroom as it distracts students. B. Students will become less creative if they always use technology for study. C. Humanities teachers can make fuller use of social media than science teachers. D. Both teachers and students need to work hard in order to use social media properly. 33. What is probably the best title for this passage?
A. Social media is popular B. Classes use social media C. Technology distracts students D. Technology is important

In 1989, a strong earthquake almost flattened America, and over 300,000 people were injured in less than four minutes. Though the earthquakes had not ended completely, a father rushed to the school where his son was supposed to be, he was surprised to find that the building was as flat as a pancake.
After a moment he came to himself and remembered the promise he had made to his son: “No matter what happens, I’ll always be there for you!” And tears began to fill his eyes. As he looked at the ruins，it looked hopeless, but he kept remembering his promise to his son. He rushed there and started digging in the ruins.
As he was digging, other helpless parents arrived, saying: “It’s too late! They’re all dead! Come on, face the fact. There’s nothing you can do!” To each parent he just replied, “Are you going to help me now?” No one helped. And then he continued to dig for his son, stone by stone.
Courageously he went on along because he needed to know for himself: “Is my boy alive or is he dead?” He dug for 8 hours … 12 hours… 24 hours… 36 hours… Then, in the 38th hour, he pulled back a large stone and heard his son’s voice. He screamed his son’s name, “ARMAND!” He heard back, “Dad! It’s me, Dad! I told the other kids not to worry. I told them that if you were alive, you would save me and when you saved me, they’d be saved. You promised, ‘No matter what happens, I’ll always be there for you!’ You did it, Dad!”
“What’s going on there?” The father asked anxiously.
“There are 14 of us left out of 33, Dad. We’re very frightened, hungry, thirsty and thankful you’re here. When the building fell down, it made a triangle(三角形)，and it saved us.”
“Come out, boy!”
“No, Dad! Let the other kids come out first, because I know you’ll get me! No matter what happens, I know you’ll always be there for me!”
34. Where did the earthquake take place? 35. Did the other parents help the father? 36. How long did the father dig in the ruins? 37. Why did the father keep digging in the ruins? 38. What is the passage mainly about?
