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（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 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 War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven（微波炉）．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, 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．

Writer and power chair adventurer Mary Laver has not walked for twenty years．Yet the cheerful and positive 60 year old is not only refusing to let her disability get her down ---- she is also planning to cross the length of Britain in a power wheelchair.
Getting ready for the trip is not easy．She has already run into many problems - not least officials and organizations who view her as a health and safety risk．One police officer wrote to Mary requesting:
1．The proposed route through our area with road numbers．
2．The dates and times each day that this will be taking place．
3．The location details of the proposed overnight stops．
4．The names and mobile phone contact details of the Support Crew．
Another police officer asked her to travel off road! As Mary told me, this was unacceptable - as a power wheelchair user with limited movement she needs to be "gettable".
There are other problems in her way though - she is, after all, in her 60's and has severe rheumatoid arthritis（风湿性关节炎）．However, unlike many other people with arthritis, she is no longer in pain.
"When you are in a power chair and it is going at eight miles an hour, believe me it feels fast … to me it is the Formula One（一级方程式赛车） chair of electric wheelchairs."
At the end of the interview, I asked Mary if she had a message for any other power chair users who wanted to do a challenge, and her reply was simple："Just do it!"

As high school students, Sang Tian and Huang Yunru dreamed of attending one of the world’s top universities．They slaved over their studies and were in the end admitted to famous schools – only one turned out to be far more famous than the other, according to new ranking （排名）of Asia’s top schools．
Huang Yunru, 19, went to the University of Hong Kong, the No 1 school in Asia．Sang, also 19, went to Tsinghua University, which was ranked a disappointing 16th in Asia．When Sang heard the news, he couldn’t believe his ears．“What? How can it be?” he said, greatly surprised.．
The new list of Asia’s top 200 universities was published last month by Quacquarelli Symonds （QS）, a UK-based career and education company．The ranking have started heated discussions among Chinese people, since the mainland’s top two schools – Peking University （PKU） and Tsinghua University – were not in the top 10.
Actually, this isn’t the first time that the schools have gone on poorly in regional or global ranking．The 2010 world university list released by the magazine US News & World Report ranked Peking University at 50th and Tsinghua University at 56th．They were the only two mainland schools in the top 100．Meanwhile, 37 US universities made the top 100 list．And three of 10 Hong Kong universities made the top 50.Chinese universities’ poor performance has saddened many students．“I can’t understand their standards,” said Sang．“At least we are a university with a long, proud history.”
According to the QS list, Chinese universities are doing OK in academic peer review, with both Tsinghua and Peking University scoring a full 100．But when it comes to student-to-faculty ratio（师生比）, their ranking drops, with Tsinghua at 22th and Peking at 23rd.John Hennessy, president of Stanford University, said at the Fourth Chinese-Foreign University Presidents Forum in early May that a lack of small-group discussions has seriously affected the teaching quality at Chinese universities．This has also resulted in students being afraid to question or challenge teachers.
1.Peking University （PKU） and Tsinghua University were in the top 10 in the ranking of Asia’s top schools．
2.There were no top 100 universities in the mainland according to the ranking.
3.Hong Kong universities are doing much better than the Chinese mainland ones in the ranking.
4.Peking University （PKU） and Tsinghua University are so famous that they are not worried about the result at all.
5.One of the reasons for the mainland’s universities’ disappointing ranking is that there are simply not enough teachers for the large number of students.

While I made painful efforts thinking over what to do, I was 8of a past incident where I needed to replace my original engagement ring 9the gold was wearing thin．My husband and I shopped and shopped for one, 10we went, even when we were on vacation． 11this nonstop searching got my poor 12to ask, "Just what kind of ring do you want, what exactly are we looking for?" My reply was, "I honestly don't 13, but when I see the correct setting, I will know it." That was the 14I felt about the new career I wished to start; I didn't have an exact idea as to what I wanted to do, but knew there was a perfect fit for me, if I would 15be patient.
