【题目】Why Do People Blink (眨眼) Their Eyes?

People blink their eyes tens of thousands of times every day. Scientists have long believed blinking was an involuntary 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 at Berkeley 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—the bony area that surrounds and protects the eyes. However, the researchers found the eyes don’t always return to the same position (位置). They said this causes the brain to tell the eye muscles (肌肉) to reorganize our eyesight.

Gerrit Maus is the lead writer of the report. He serves as an assistant professor of psychology at Nanyang Technological University in Singapore. Maus said, “Our eye muscles are quite sluggish (迟缓的) and imprecise (不精确的), so the brain needs to constantly adapt (改编) its motor signals to make sure our eyes are pointing where they should be. Our findings suggested that the brain measures the difference in what we see before and after a blink, and orders the eye muscles to make the needed corrections.” The researchers said that without such corrections our surroundings would appear unclear and even jumpy. They said the movement acts “like a steadicam (摄影稳定器) of the mind.”

The researchers said they asked volunteers to sit in a dark room while storing 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 the volunteers did not consciously register that the dot had moved, their brains did, and adjusted (调整)with the corrective eye movements. These findings add to our understanding of how the brain constantly adapts to (适应) changes directing our eye muscles to correct for errors in our bodies’ own hardware.”

【1】According to the new study, blinking eyes can ________.

A.serve keep the eyeballs wetB.reposition eyeballs to stay focused

A.reasonB.refocusC.realizeD.reserve

【4】This passage shows that ________.

A.eye muscles are quite inactive and imprecise

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

【题目】

Once a king got two nice falcons（猎鹰） from his son. He had never seen such beautiful falcons before. He loved them so much and he ordered the best falconer to train them to fly.

After several months, the king came to see how the training was going. He found that one falcon had already been able to fly high in the sky, while the other was staying on the branch（树枝） of a tree quietly, just keeping still.

The king called all his falconers together and ordered them to try every way they could to make the other falcon fly. But none of them succeeded. One day, while the king was taking a walk in the forest, an idea came to his mind. Maybe someone who knew the natural environment well could solve this problem. He sent for a farmer who lived in the forest into his palace to train it at once.

The next mornings, the king saw the other falcon flying above in the sky freely. “It is unbelievable!” shouted the king. “How could you make it happen?”

The farmer replied, “It’s very easy. I just cut off the branch where the falcon rested.”

It is always the same to human beings. We all have “two flying wings” in our hearts as well, but we often seem not to no notice them and stay where we are just for safety and comfort. We won’t realize we can fly so high and freely until the “branch” we are resting on breaks.

根据短文内容，回答下列问题。

【1】What did the king do after he got two falcons?

______________________________________________________________________________

【2】Where was the other falcon staying?

________________________________________________________________________________

【3】Who finally made the other falcon fly in the sky?

___________________________________________________________________________________

【4】How did the king feel when he saw the other falcon fly freely in the sky?

_________________________________________________________________________________

【5】When will we realize we can fly so high and freely?

_________________________________________________________________________________
