Nowadays, many children spend hours a day looking at computer screens or other digital (数码的) products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (视力综合症).
Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. “More children come into my office because their parents have noticed that they have headaches (头疼)or red eyes, or because their degree of short-sightedness appears to be increasing (增加)very fast and they’re worried,” he said.
Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away. Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.Which of the following may be caused by too much screen time?
| A．Having wet eyes. |
| B．Having headaches. |
| C．Having small eyes. |
| D．Having a toothache |
Why don’t some children tell their parents when their eyes start to feel uncomfortable?
| A．They think it is not serious. |
| B．They want to continue playing computer games. |
| C．They don’t want their parents to worry. |
| D．Their parents don’t care about them. |
People blink about as they normally do when they use computers.
| A．a third as much | B．two thirds as much |
| C．half as much | D．as much |
From the passage, we can learn that .
| A．children should blink as much as possible |
| B．tears can’t protect eyes |
| C．blinking is good for eyes |
| D．It’s useless to blink. |
What is the passage mainly about?
| A．Some information about the latest digital products. |
| B．Dr. Warford’s experience of working out eye problems. |
| C．Eye problems in children caused by using digital products. |
| D．It’s bad to use computers . |

The word, “photography”, was first used in 1839. It comes from the Greek words that mean “to write with light”. But photography could only give peoplestatic pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.
Back in 1872, people didn’t know exactly whether all four of a horse’s hooves (蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn’t think so.
At that time, it was hard to know who could win the bet, because a horse’s legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn’t give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence (连续) of 12 photos. One of them clearly showed that all four of the horse’s hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.
Though is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison’s invention.The underlined word“static”in Paragraph 1 most probably means _______.
| A．pretty | B．dark | C．moving | D．still |

Muybridge finally found the exact answer to the bet _______.
| A．next year. | B．at the same year. |
| C．after six years. | D．after seventeen years. |
Which is TRUE from the passage?
| A．The word, “photography” means to make pictures that can move from the Greek words . |
| B．Leland Stanford made a bet with Edison in 1872. |
| C．It is very easy for Muybridgea to record the movement of a running horse. |

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly(紧紧地）in a bamboo tube(管子and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for “Pemberton’s French Wine Coca”, his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.
3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.The underlined phrase “ blew up” might mean _______ in Chinese.
