Being good at something and having a passion for it are not enough. Success 1 fundamentally on our view of ourselves and of the 2 in our lives.
When twelve-year-old John Wilson walked into his chemistry class on a rainy day in 1931, he had no way of knowing that his life was to change completely. The class experiment that day was to 3 how heating a container of water would bring air bubbling(冒泡) to the surface. 4 the container the teacher gave Wilson to heat 5 held something more volatile(易挥发的) than water. When Wilson heated it, the container 6 leaving Wilson blinded in both eyes.
When Wilson returned home from hospital two months later, his parents attempted to find a way to deal with the catastrophe that had 7 their lives. But Wilson did not regard the accident as catastrophic. He learned braille(盲文) quickly and continued his education at Worcester College for the Blind. There, he not only did well as a student but also became a(n) 8 public speaker.
Later, he worked in Africa, where many people suffered from 9 for lack of proper treatment. For him, it was one thing to 10 his own fate of being blind and quite another to allow something to continue 11 it could be fixed so easily. This moved him to action. And tens of millions in Africa and Asia can see because of the 12 Wilson made to preventing the preventable.
Wilson received several international 13 for his great contributions. He lost his sight but found a 14. He proved that it's not what happens to us that 15 our lives—it's what we make of what happens.
In June, China's last satellite of its BeiDou Navigation Satellite System(BDS) was launched into orbit, marking the completion of the whole system.
In ancient China, people used the Big Dipper, is known in Chinese as "beidou qixing", to navigate.China's navigation satellite system (name)after "Beidou", which carries the meaning of "pointing out the right direction". China started constructing the BeiDou Navigation Satellite Experimental System(BDS-1) back in 1994, and now it consists of 55 satellites and can provide services worldwide.
(compare) with other satellite navigation systems, the BDS operates more satellites in high orbit, and transmits navigation signals at more frequencies.These features enable better more accurate services.Apart navigation, the BDS also provides diverse services, such as short message communication, and free international search and rescue (assist). The BDS has been applied in transportation, agriculture and other traditional fields.
As open system featuring shared benefits, the BDS has been seeking to serve a (wide) range of countries and international organizations. BDS-related (product), as is reported, are now being used in more than 120 countries and regions.Projects based on the BDS for precision farming, smart port construction and digital construction have been carried out in many countries across Asia, Europe and Africa.China is also (active) communicating with Russia and European countries (improve) the compatibility of the BDS so that it can better serve its global users.
