Passage 1
We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly becau as we stare at our devices we are exposing ourlves to blue light.
Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue—light—blocking glass are so popular. So, do the glass work?
“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing rious damage,” Dr. Rahul Khurana, a clinical spokesman, told Business Insider.
Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also prent in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens? The answer is eyestrain(眼疲劳). More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it ems isn’t the cau. Instead, our eyes are so strained becau most of us blink less when we stare at our digital devices. So, if eyestrain is the real issue, blue-light-blocking glass are probably of little u.

Passage 2
One sunny afternoon in the autumn of the year 1861, a soldier lay in bushes by the side of a road in western Virginia, America. He lay at full length upon his stomach, his head upon his left forearm. His right hand looly grasped his gun. But for the slight rhythmic movement of his back, he might have been thought to be dead. He was asleep at his post of duty. But if found, he would be dead shortly afterward, death being the legal punishment for his crime.
The sleeping soldier was a young Virginian named Carter Dru. He was the son of wealthy parents, an old child. His home was but a few miles from where he now lay. One morning he ro from the breakfast table and said riously:’ Father, the Union army has arrived at Graton. I am going to join it. ‘
The father lifted his head, looked at his son a moment in silence, and replied,’ Go Carter, and whatever may occur, do what you consider to be your duty. Virginia, which you betray, must get on without you. If we both live to the end of the war, we will speak further
of the matter. ’
So Carter Dru, bowed to his father and left the home of his childhood. His bravery won him his lection for his prent duty at the extreme post. Nevertheless, he fell asleep, exhausted. What good or bad angel came in a dream to awake him from his state of crime, who shall say? He quietly raid his forehead from his arm and looked between the bushes.
His first feeling was a great artistic delight. On the cliff(悬崖) was a man sitting on a hor, straight and soldierly. The face of the rider turned slightly away; he was looking downward to the bottom of the valley.
Fully awake and keenly alive now, Dru cautiously (谨慎地) pushed the gun forward through the bushes and covered a spot of horman’s breast. A touch upon the trigger(扳机) and all would have bene well with Dru. At that moment, the horman turned and looked in his direction—emed to look into his very face, into his eyes, into his brave heart.
Dru grew pale; his whole body shook. His hand fell away from his weapon, and his head slowly dropped until his face rested on the leaves.
The duty of the soldier was clear—the man must be shot dead. But no –there is a hope; he may have discovered nothing—perhaps he is but admiring the beauty of the landscape. Dru looked downward. He saw some foolish soldiers watering their hors in the open!
