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 in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist(藥劑師), 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.

London’s Chinese community(社區(qū)) dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limhouse, east London. As time went on, other Chinese came to this area and Limhouse began to be known as “Chinatown”. However, London’s Chinese community remained every small for many years: at the start of the 20th century, there were just 545 Chinese people in Britain.
After the Second World War, many farmers in Hong Kong lost their jobs and came to London. As Limhouse had been almost destroyed during the war, they settled (定居) in a different area—a port of central London near Leicester Square. This area is now what Londoners call Chinatown.
At first, the new immigrants found it difficult to get jobs. In the 1950s, however, a small Chinese restaurant opened in London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants and take-ways started opening in every part of the city. Instead of too little work, the new Chinese immigrants now found that they had too much! They worked as cooks, managers or waiters. Most of them enjoyed their lives and arranged their friends and relatives to join them from overseas.
As time went by, London’s Chinese community became more and more successful. The sons and daughters of the original restaurant workers studied and worked very hard. And most went on to get highly paid jobs. Many Chinese families left Chinatown and moved to more expensive outskirts. Chinatown, however, is still as lively as ever.
小題1:When did the first Chinese immigrants come to London?
A. In the 1950s.
B. B. More than 200 years ago.
C. C. At the start of the 20 century.
小題2:Why did many Chinese immigrants come to London in the 1950s?
A. Because it was easy for them to get jobs there.
B. Because many British people enjoyed Chinese food.
C. Because their children could study there and get highly paid jobs.
小題3:In the 1950s, Chinese immigrants came to London and worked as _______.
A. sailors
B. sailors and farmers
C. restaurant workers
小題4:Where is London’s Chinatown now?
A. In the east of London.
B. In Limhouse.
C. Not far from Leicester square.
小題5:According to this passage, if people live in the outskirts of a city, they live ______.
A. in the center of the city
B. in the outer areas of the city
C.in the busiest part of the city.

What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck.
If you arrange the 26 English letters alphabetically(按字母表的順序)and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11="98," meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5="96," while love :12+15+22+5="54," and luck : 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money or prayer(祈禱)? They can’t, either.
Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark.
Different attitudes lead to different courses of life. Most times people hope for a better life. It is possible that one will have a change for the better after one has changed one’s attitude.
When you change your manner and become friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive attitude towards failure(失敗), you’ll find it’s also rewarding though it has caused you losses.
小題1:In the writer’s opinion, what is the most important things in a person’s life?
A．Hard-work.B．Knowledge.C．Money.D．Attitude.
小題2:According to the passage, what’s the mark of the word “succeed”?
A．50B．60 C．70D．80
小題3: What does the underlined word “positive” mean in the text?
A．正面B．反面C．積極的D．消極的
小題4:According to the passage, if you meet with problems, the best way out is to ___________.
A．change your attitudeB．say your prayers to God
C．a(chǎn)sk for help from othersD．try math-solving methods
小題5:From the passage we can learn that ______________.
A．different attitudes come from different courses of life.
B．mathematics can solve every problem easily in our daily life
C．failure sometimes can bring you good if you take a positive attitude
D．none of the English words except “attitude” equals to 100 or more
