Dr Robert Hutchings Goddard is regarded as the father of modern rocket propulsion(推进）。As a physicist of great insight,Goddard also had his unique gift for invention.It was in honor of this brilliant scientist that NASA's Goddard Space Flight Center in Greenbelt,Maryland,was set up on May 1,1959.
Goddard first obtained public notice in 1907 in a cloud of smoke from a powder rocket fired in, the basement of the Worcester Polytechnic Institute's physics building.School officials took an immediate interest in the work of the student Goddard. The school's administration,to his surprise,did not expel him.He thus began his lifetime of fine work.
In 1914,Goddard received two U.S.patents.One was for a rocket using liquid fuel.The other was for a two-or three-stage rocket using solid fuel.
By 1926,Goddard had constructed and successfully tested the first rocket using liquid fuel. At that time,Goddard' s rockets left little impression on government officials.Only through modest amount of money from the Smithsonian Institution and the Daniel Guggenheim Foundation was Goddard able to sustain his devoted research and testing.
Goddard' s greatest engineering contributions were made during his work in the 1920s and 1930s.He received a total of $10,000 from the Smithsonian by 1927,and through the personal efforts of Charles A.Lindbergh,he later received financial support from the Daniel and Florence Guggenheim Foundation.
Goddard 's work largely anticipated the later German V-2 missiles in technical detail.His rocket flight in 1929 carried the first scientific payload(有效负荷），a barometer(气压计）and a camera.During World War II,Goddard was appointed by the U.S.Navy to the development of practical jet-assisted takeoff and liquid propellant(推进燃料）rocket motors capable of variable thrust.In both areas,he was successful.Robert H.Goddard died on August 10,1945,four days after the first atomic bomb was dropped on Japan.

Kids,whose imaginations have no limit,frequently come up with inventive ideas.However,few see them come to life mainly because adults don't believe in their practicality.That is about to change thanks to Little Inventors,an innovative(创新的）project that connects inventors to producers and artists who can help bring even the most impossible invention ideas to life.
The project is the brainchild of Dominic Wilcox,a British artist and inventor,who is world-famous for his fun creations like GPS shoes that can find their way home.Wilcox,who was encouraged to create things at a very young age by his teacher,believes that"we are all born creators"and thinks children's ideas are just as valuable as those of adults'.
The chain of events leading to the founding of Little Inventors dates back to a series of workshops held by Wilcox around his hometown of Sunderland,England in 2015.The 19 events, organized to encourage children aged 5-12 to describe their ideas,were a huge success,attracting over 300 kids and resulting in more than 450 fun inventions.The designs were presented to a group of twenty-three local artists and producers who selected one idea and then worked alongside its young creator to bring it to life.
The success of the workshops has led to the creation of Little Inventors.The website allows inventors from all over the world to submit their invention ideas.Though not all submissions will be built,inventors will receive valuable feedback on their designs and also suggestions on ways to
improve them.So,upload an idea or two to little inventors.org and see if you can make your crazy,or world-changing invention a reality.

The 90-minute documentary,Amazing China,is coproduced by China Central Television and China Film Corp.The film focuses on the major achievements the country has made since the 18th National Congress of the Communist Party of China in 2012.
Wei Tie,the director,says,"The film arouses Chinese pride from deep inside."
The documentary focuses on key Chinese projects in aerospace,high-speed rail,the Hong Kong-zhuhai-macao Bridge and the world's largest single-dish telescope FAST.

Li Dan is an exchange student in a British high school. She sat next to a girl name Diana. The headmaster told the students that the best way earn respect was to devote themselves to study and achieve high grade. Although the homework was not heavier than before, but it was a bit challenging for him at first because all the homework was in English. Fortunate, all her teachers gave her much encouragement. To improve her English, she spent an hour each day read English books in the library. In the word, studying in Britain was a very enjoyable and excited experience for Li Dan.
