Do you know anything about the invention of the bar code（条形码）
A small food store owner found it was 1 to keep records of the products' information. In 1948, he asked the Drexel Institute of Technology to solve this problem. Bernard Silver, a graduate student, was interested. He and his friend Norman Joseph Woodland 2 to work on it. Soon, they 3 their first working system.
The system did work 4 , but it was very expensive and sometimes the system didn't work well. If the invention was to become popular in 5 , the problems had to be solved. Finally, Woodland solved 6 .
The patent（专利权） for the bar code system was 7 for by Silver and Woodland in 1949, but the patent was not given until1952. 8 this patent was given, the system was still not popular 9 store owners.
In 1970, a business named Logicon Inc. invented the Universal Grocery Products Identification Code（食品工业统一码）. Marsh Supermarket in Troy was the first store to 10 this bar code reading system. It has become very popular ever since, and now it's used in all types of stores all over the world.

What will the future world be like Many people are glad to give their 11 . Here are two imaginations about the world of tomorrow. When people talk about the future, we like to think that we’ll have our own personal flying car. We would fly at 480 kilometers per hour, avoiding traffic lights, 12 roads and speeding tickets. However, some people point to the disadvantages of flying cars. One big problem is: what will happen if the flying cars 13 Then there will be problems with traffic control. Also, if they become popular, there will surely be too much air traffic. So it seems that flying cars will face more than a few problems if they are to get off the ground! Imagine you have your own Ironman 14 . Several companies are trying to build a practical robot “exoskeleton”. This is a suit of robot arms and legs which follows your movement. It will 15 the wearer to lift heavy objects, walk a long way and even punch through walls! It is 16 in many ways, especially for people with disabilities. This suit might help people to walk again after 17 or injury (受伤). But the disadvantage at the moment is the 18 . Even a simple suit can cost hundreds of thousands of pounds. Another problem is battery life. A suit like this needs a lot of 19 and batteries only last about 15 minutes at the moment. One other problem is that a badly programmed robot suit could harm the wearer. You wouldn’t want your robot leg or arm bending (弯曲) suit could 20 the wearer if he wears it the wrong way.
So in the future, although we might be able to fly to work and lift a car above our heads there are plenty of problems to solve before this will be possible.

The game of baseball in the United States is the oldest major league (职业联盟) sport in the country.

Cricket is a very popular sport in England, but it is mostly played by the rich instead of the 24 . However, it is similar to the game of rounders (圆场棒球), which is another English sport that shares many common characteristics as the American game of 25 .
In any event, the game became very 26 in the United States. By the 20th century, the American League and the National League were taking the country by storm. The greatest 27 in either league’s history is the New York Yankees. The Yankees have won more World Series titles than any other team in history.
The World Series is a seven game 28 with the two top teams from either league. The first team to win four games is announced the World Series Champion. In 1903, the Boston Americans 29 the first World Series beating the Pittsburgh Pirates. To date, the Yankees have won 27 of the 40 competitions, with 30 the team’s most recent title in 2009.

Chewing gum(口香糖) may be one of your favorite sweets. But do you know how it was 111 The inventor of the chewing gum is an American scientist called Thomas Adams. He made it completely 112 .
It was 1869. Earlier that year, one of Adams’ friends showed him an interesting kind of sap(树汁). His friend told him 113 people in Central America liked to chew(咀嚼）on it for fun. Hundreds of years passed, people didn’t do that any longer. But Adams was interested in the sap. He wanted to use it to create some new 114 . Adams, however, 115 to create what he wanted.

Later in 1869, he opened a factory to produce this delicious 118 .
In 1888, Adams gave a 119 to the invention “chewing gum”. The sweet can be got from selling machines at underground stations all over New York City. Over the years, new kinds have been 120 .

My father died when I was nine, and I remember doing chores to help my mother. I hated changing the vacuum cleaner (真空吸尘器) bag and picking up the things the machine 131 to take in.
Twenty years later, I was doing chores at home with my wife and I had to empty the bag because I could not find a new one. I had always hated the way the machine worked and I decided to make a vacuum cleaner without 132 .
Easier said than done, of course. I didn’t 133 that I would spend the next five years perfecting my design, a process that resulted in 5, 127 different prototypes (设计原型). By the time I made my 15th prototype, my third child was born. By 2, 627, my wife and I were really short of money. By 3, 727, my wife was giving art lessons for some money. These were hard times, but each failure brought me closer to 134 the problem.
However, at first I 135 thought of going into a business with it. In the early 1980s, I started trying to get a license for my technology. The reality was very different, though. The big vacuum makers made most of the money from bags. No one would license my idea, not because it was a 136 one, but because it was bad for business.
The unfairness gave me the 137 to keep going, but soon after, the companies that I had talked with started making machines 138 mine. I had to fight to protect the patents (专利) on my invention. My invention didn’t go into production 139 a bank lent me 1 million pounds in 1993. Within two years, my invention—the Dyson vacuum cleaner—became a success in Britain.
Today, I still welcome risk and failure as part of the process. 140 beats the excitement of invention. Go out and brainstorm your ideas. Rules can’t get in the way of you. In fact, the stranger and riskier your idea is, the better.

When you think of robots, you might think of something to finish boring tasks, 141 engineers are making robots that can do much more interesting jobs.
Howie Choset at Carnegie Mellon University in Pittsburgh is a roboticist, a person 142 designs, builds or programs robots. When Choset was a kid, he was interested in anything that 143 —cars, trains, animals. Later, in high school, he built mobile robots similar 144 small cars. Hoping to continue 145 robots, he studied computer science in college. Some robots can move only forward, backward, left and right, 146 snakes can twist in many directions. “Snakes are far more interesting than the cars,” Choset said.
After he started working at Carnegie Mellon, Choset and his colleagues there began developing 147 own snake robots. A typical snake robot is made up of a lot of metal containers linked together, each with a motor and electronic parts 148 . Choset’s team programmed robots to perform the same movements like real snakes. The robots also moved in ways that snakes 149 don’t, such as rolling. Choset’s snake robots could crawl 150 the grass, swim in a pond and even climb a flagpole.

Though chopsticks are used in many Asian countries, they have their beginnings in China. Chinese 171 says that China had chopsticks as far back as the Xia Dynasty（夏朝），In the Spring and Autumn Period copper and iron chopsticks appeared. Then in the Han Dynasty lacquered（涂漆）chopsticks came. Gold and silver chopsticks followed later. Today we have chopsticks 172 of plastic. The most expensive ones are made of tusks of elephants and hard green stones.
Chopsticks tell Chinese: tradition in their way. In ancient times the rich used gold chopsticks 173 their wealth. In history many kings used silver chopsticks to take their food to see 174 it was poisonous（有毒的）. It was said that if it was，the silver chopsticks would 175 color. Chopsticks are traditionally given to a daughter when she marries to show that they should have a son very soon, for “chopstick ” in Chinese is pronounced, 176 “quick a son”!
Tianzhu chopsticks from Hangzhou, wooden chopsticks from Shangyang of Shaanxi Province, and Beijing’s chopsticks are 177 . Chopsticks appeared in the old Chinese story: An old man 178 his sons a lesson by showing how he can easily break a single chopstick but not a number of them. In China chopsticks are 179 good luck.

One of the easiest ways to stop the spread of disease is to simply wash your hands. Twenty seconds of handwashing with soap and water can reduce 181 and save lives. But, many people, especially children, do not have good handwashing habits. One problem is that children do not wash their hands often enough or long enough. Children may think that it is a 182 thing to do.
To help solve this problem, Amanat Anand and Shubham Issar from India created a product called the SoaPen (肥皂笔) to turn handwashing into a 183 activity.
As the name suggests, the SoaPen is a pen made out of soap that kids can 184 with. The children draw on their hands with the soap pen and then wash it off. If 185 do not spend enough time washing it off, the colors will remain on the children’s hands. It’s a fun way to teach kids how to wash their hands.
Issar said the SoaPen is invented to teach kids good handwashing habits and it ensures that children spend enough time washing their hands. This may be especially 186 in a classroom. Often a teacher does not have the time to ensure that each child has washed their hands 187 .
“Kids actually wash their hands for the proper amount of time 188 they’re drawing on their hands, and under water they have to rub really hard to remove the drawing. So they are actually washing their hands 189 just going under water.”
The product could have a great 190 on public health. The United Nations International Children’s Emergency Fund (UNICEF) reports that 1.5 million children die each year as a result of diarrhea. UNICEF says good handwashing habits could reduce that number by 40 percent.
