1．Imagine looking for your lost dog．You step into a cave（洞穴）．But instead of the dog，you find beautiful cave paintings．You see paintings of horses，deer，and bison that are drawn in black，brown，red and yellow．Your first question would probably be"Who did this？"
This is what happened to four French boys in 1940．They found the Lascaux caves．The paintings the boys discovered in those caves are 17，000years old．They were drawn by the ancient people called Cro-Magnons．
Cro-Magnons looked much like people of today．They used tools，such as fishing nets．But their art was extremely good．The main cave at Lascaux is called the Great Hall of Bulls，which has a picture of bulls and horses in many colors．The largest animal is 18feet long．There are smaller animals，such as bison，stags（雄鹿） and a bear．There is also a strange spotted two-horned （两只角的） animal．
To the left of the main cave are the most famous paintings that are the drawings of multicolored animals．One painting is called Little Horses．On the ceiling are horses and cows．The most unusual sight may be in the Shaft of the Dead Man where there is a thinoceros （犀牛），a carefully drawn dead man，a wounded bison and a bird．
Why did Cro-Magnon artists do these beautiful drawings on cave walls？Did the drawings call upon some magical power？Did the Cro-Magnon people hope that the drawings would bring good luck？There is one thing the paintings seem to tell us．The Cro-Magnons were interested in the world．They looked at beauty and they understood it．

15．Mark Twain was a great writer．He was from the USA．He was born in 1835．He was also a famous speaker．He was famous for his sense of humour．Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time．
One day Mark Twain was going to a small town because of his writing．Before he was going to leave，one of his friends said to him that there were always a lot of mosquitoes（蚊子） in the town and told him that he'd better not go there．Mark Twain waved （摇动） his hand and said，"It doesn't matter．The mosquitoes are no relatives of mine．I don't think they will come to visit me．"
After he arrived at the town，Mark Twain stayed in a small hotel near the station．He went into his room，but when he was just about to have a rest，quite a few mosquitoes flew about him．The waiters felt very sorry about that．"I'm very sorry，Mr Mark Twain．There are too many mosquitoes in our town．"One of them said to him．

5．It's often said that the eye is the window to the soul．But in this case，the eye is the window to Windows．At least，that was the goal when EyeTech Digital Systems got the help of some BYU engineering students in creating an all-in-one eye-tracking system．
The idea behind the project was to create an inexpensive computer system that could be controlled completely with a person's eyes．The hope was that this system could be used by people with disabilities in parts of the world where they can't afford expensive eye-tracking systems．The students created the tablet（书写板）for their yearlong engineering project for their customer，EyeTech Digital Systems，an Arizona-based company that designs and develops eye-tracking software．
A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye-tracking tephnology，but this year's focus was to put the eye tracking into a housing similar to a thick PC．The finished product runs Windows 7 and has the eye-tracking system built in．After a quick adjustment，the system can move the mouse to wherever the user is currently looking．All it takes is a blink（眨眼）to click．
Systems with similar abilities can cost upwards of 14，000．Butthestudentswereabletofindcheaper，readilyavailableparts，pushingthecostdowntounder1，500．Jedediah Nieveen，the captain for this year's team，said the project was a challenge，but one that was rewarding on many levels．"A lot of times in school you just work problems out of books，"he said．"But this allowed us to take what we learned and apply it to something in real life，something that can help a lot of people，and that's really helped me．"
Although the primary purpose of the product is to help people with disabilities，the technology could also have broader applications in the fields of research，advertising and even gaming．
