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 _______.

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 . |

| 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.

Smoking in indoor public places including public working places, public transport vehicles and some other special outdoor working places has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.
First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled.
Next, banning smoking will put stress on smokers to give up. Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
Smoking in public places influences non-smokers to start smoking, especially adolescents. When teens see people around them smoking, they will follow them easily. Thus the number of teen smokers will increase. Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
Looking from the economic point of view, smoking should be banned to increase work productivity(生产率).Employees(雇员)who smoke usually take breaks to smoke while working. So the number of hours they put in their work is smaller.
If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse.
________doesn’t belong to a non-smoking place.
| A．A field | B．A hospital |
| C．A library | D．A restaurant |
The second paragraph mainly wants to tell us ______.
| A．banning smoking is good for restaurants |
| B．banning smoking is good for non-smokers |
| C．banning smoking is good for spread of diseases |
| D．banning smoking is good for active smokers and passive smokers |
How many advantages of banning smoking are mentioned in this passage?
| A．Two. | B．Four. | C．Five. | D．Six. |
According to the text, the underlined word “adolescents” means ______.
| A．men | B．women | C．adults | D．teenagers |
Which of the following statements in NOT true?
| A．If smoking is banned, work productivity will increase. |
| B．If smoking is banned, the number of teen smokers will be larger. |
| C．If smoking is banned, it will make the environment become better. |
