Question: Article: To Chinese immigrants, in the mid-1800s, California was "The Land of the Golden Mountain." In their homeland they had heard the words, "There's gold in California." They sailed 7,000miles to join the gold rush and strike it rich. Between 1849 and 1882, more than 30,000 Chinese came to California. Most were men. They had been farmers in China. They came here to be miners and laborers. They ended up doing many other jobs, too. Like many other immigrants, they did not plan to stay in America. They came because of their ties to their homeland and their families. They planned to return to China with their fortunes and help their families. Only a few Chinese gold miners struck it rich. Most picked over the areas that had been mined already. But still, white miners _ the Chinese. Slowly, they drove the "yellow peril" from the mining camps. By the end of the 1850s, many Chinese returned home. Those who stayed found other jobs. Few women had come west in the gold rush. The Chinese saw a good business opportunity. They began doing the jobs women would have done. Many became house servants. Many more opened laundries. The Chinese opened restaurants. Chop suey and show mein are popular Chinese-American dishes. The Chinese probably created these dishes to serve to the white miners. Other Chinese became fishermen, farmers, and even cigar makers.

Question: Article: Do you want to write your password down so that no one can see it, or do you want to send someone a secret message? Knowing how to make an invisible ink message will have you feeling like a secret agent in no time. These are instructions for making invisible ink using baking soda. Difficulty: Easy Time required: A few minutes  What you need: Baking soda, Paper, Water, Light bulb, Paintbrush, Measuring cup, Purple grape juice Here's how: There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and baking soda. Use a paintbrush to write a message onto white paper, using the baking soda solution   as "ink". Allow the ink to dry. One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking soda will cause the writing in the paper to turn brown. The second way to read the message is to paint over the paper with purple grape juice. The message will appear in a different color1. Tips: If you are using the heating method, avoid burning the paper. Baking soda and grape juice react in an acid-base   reaction, producing a color1 change in the paper. Grape juice concentrate   results in a more visible color1 change than regular grape juice.

Question: Article: Of all the famous English writers, probably the best known is William Shakespeare. He was born in Stratford-upon-Avon in 1564 on April the 23rd. His father was an important man in town so Shakespeare had a good upbringing. Shakespeare probably went to school (although no records survive to prove this) but not university. He got married when he was 18 to Anne Hathaway and the couple had 3 children. Shakespeare wrote 38 plays and 154 sonnets (a sonnet is a kind of poem). He began working in his home town of Stratford but by 1592 was writing in London. He became rich enough to buy a house in the capital and one in Stratford.  He wrote sad stories called tragedies, like Romeo and Juliet, funny stories or comedies, romantic stories and stories about historical figures such as Julius Caesar.  Shakespeare died on his birthday in 1616, almost 400 years ago. But why is his work still popular today? His work looked at common human themes, such as betrayal, murder, lust, power, ambition and love. These themes are as much a part of human nature today as they were all those years ago and are the themes we see in modern soap operas and Hollywood films. Even though his theatre, The Globe, burned down in 1613 it was rebuilt in London in 1997 and you can still see his plays performed there today. Shakespeare's influence on the English language can still be felt today. We talk about "fair play", meaning honest behaviour but this phrase was first used by Shakespeare. He coined the phrase "you can have too much of a good thing". And it was Shakespeare who came up with the expression to disappear "into thin air" which we still use today when we lose something. Shakespeare's work has been translated into every major language in the world. And perhaps we'll still be as fascinated by his work 400 years from now as we've been for the last 400.
