At that time, African-Americans in the Deep South were still suffering from the __appalling_disadvantages in many aspects. His six weeks’ life as a Negro is horrible.His amazing story _exposes_ the racist treatment towards the black people. Small __humiliations_ are routine.

Without water, no life would be possible on this planet. Ancient cultures and civilizations --worshipped-- water and--equated-- it with life force. But conventional science treats water as a --lifeless --substance and promotes reproducibility as the basic premise of science. It is impossible for water to be always--reproducible-- , so the testing of natural phenomena concerning water becomes very difficult. Water has an ability to shape organic forms. Due to its natural desire to flow in --spirals--, the tissue of human heart and arteries is formed with a twist and the fibres of the tissue can run in a spiralling way so that blood also can spiral by flowing through these vessels. Moreover, water can have the memory of water phenomenon.Water molecules often form clusters by attaching themselves to each other. These clusters are so --sensitive--that they will be impressed by any vibrational influence and store such information.Thus water will take on the --imprints--of environmental pollutants and transfer them to people when they drink it. Therefore conventional water and sewage treatment systems are not adequate. Tap water, though --chemically--clean, still convey the --vibrational--pattern of toxins and chemicals to the human body.
Iron ore, the fifth _abundant_element on earth was not fully recognized as a useful natural source before the Hittites learned the way to _derive_iron from ore. With the development of metallurgy, iron was strengthened and hardened through heating over a bed of charcoal. However, the steel produced in this way might __rust__ in __humid__ air. And when the steel was employed in guns, the spinning of the bullet would lead to __erosion__in the gun barrel, which inevitably affects the __accuracy_of shooting. So in 1908, Harry Brearley was __commissioned__ to find ways to ___eliminate__ the erosion in steel. Months passed before Brearley one day accidentally noticed that some samples __tossed__ into a junk pile still kept the ____luster__ after a long time. This discovery helped him eventually solve the problem and thus “rustless steel”came into being. Later the name was changed into “stainless steel”when a manufacturer found the steel might be kept from staining after being dipped into vinegar.。
