How Colored Crayons for Kids Were Invented

You can buy a box of Crayola crayons in 152 colors today, but way back in 1903, they only came in eight colors. And that first box of Crayola crayons was a huge improvement over the first crayons ever sold, which only came in black.

Wax(蜡) crayons were mostly used for industrial purposes until cousins Edwin Binney and Harold Smith introduced their brightly colored crayons for kids. Edwin's wife made up the name Crayola by putting together “craie”(French for chalk) together with “oleaginous”(which means oily). In other words, oily chalk!

It's hard to understand just how different modern crayons are from those in the past without a look at the history of the crayon. In 1864 Edwin's dad, Joseph Binney, started the Peekskill Chemical Works in New York City. It made a black pigment(颜料) by burning oil.

When the two cousins took over in 1885, they started making a number of industrial products, but from 1900 to 1902, they changed their focus to art products for home and school use. They started making pencils and dustless chalk for school blackboards. Colored crayons were a natural next step. But the crayons they first made were not safe for kids, so they developed crayons that would be safe. The first box they sold, the one with eight colors, cost just five cents.

To celebrate the hundredth birthday of Crayola crayons in 2003, a special 100-count box was created, adding four new

colors to the existing(现有的) 96-color box. Over the years, as the company has grown, it has introduced more than 400

different colors. Also you can find crayons that smell good, crayons that wash out of clothes, and even egg-shaped crayons.

Nowadays, plenty of other companies make colored crayons for children, too.

Fifty Jobs in Fifty Weeks

Daniel was disappointed as he walked out of his 40th job interview. He couldn't believe he had failed 40 interviews. He just finished his university study and needed to get a job fast. He was almost broke(身无分文的). He decided that he would start a new project called “Living the Map”. He wanted to get 50 jobs in 50 states in only 50 weeks.

Daniel's idea may sound crazy, but it is really clever. Daniel said that one of his goals was to get as much job experience as possible. He was still not sure what kind of job he really wanted. The best way to find out was to try out different types of jobs. So, he tried to get jobs that were related to each state's identity(特点). For example, Michigan is famous for having a lot of car factories, so during his week in Michigan, he worked as a mechanic. Wisconsin is known for its cheese, so he was a cheese maker there. In Vermont he made maple syrup, and in Maryland he was a crab chef.

Daniel not only had fun trying all kinds of interesting jobs, but he also made 60，000 dollars and became famous. He plans to publish a book about what he learned from his project. At the beginning, Daniel wanted to get as much job experience as possible, but instead became famous—or was he hoping to become famous from the beginning? You decide. Whatever he had in mind, it looks like there are many more jobs in his future.

( )2.Where did Daniel work as a cheese maker? A．In Michigan. B．In Wisconsin. C．In Vermont. D．In Maryland.

Humans' Love of Sugar

It is quite fair to say that our ancestors(祖先) were responsible for our sweet teeth. Millions of years ago, our ancestors lived on sugar-rich fruit. They liked fully-grown fruit, because it had more sugar and

supplied more energy. And sugar helped them store fat, too. Early humans often had very little food, so their bodies learned to be very good at storing sugar as fat. In this way, they had energy stored. When there was no food, their bodies burned the stored fat to get energy to live on. At that time, hanging on to fat was an advantage, not a health risk.

“But today, most people have more sugar than enough. The average sugar intake(摄取量) in the U．S. is 22 teaspoons a person a day, which is four times the amount that the World Health Organization(WHO) suggests is healthy. So the very thing that once saved us may now be killing us. One-third of adults worldwide have high blood pressure, and up to 347 million have

diabetes(糖尿病). Why? Sugar is one of the causes, if not the main cause，” says scientist Richard Johnson.

And many scientists believe our love of sugar may actually be an addiction. When we eat or have sugary foods or drinks, the sugar enters our blood and affects parts of our brain, which makes us feel good. Then the good feeling goes away, leaving us wanting more. In this way, it is addictive.

So what should we do? It's obvious that we need to eat less sugar. But the answers are not so easy. In today's world, it's really difficult to avoid sugar. From breakfast bread to after-dinner cookies, our foods are increasingly filled with it. Some food

producers even use sugar to replace taste in foods that are advertised as low in fat. This may make the food appear as healthier, but large amounts of sugar are often added.

But there are those who are fighting back against sugar. Many schools are offering healthier food with less sugar. Many
