Step 1: Warming up by defining sciences

Biochemistry: A branch of chemistry studying the chemical behavior in living beings. Biochemistry is not only interested in the individual chemical components but also their vital interplay.

Biology: the science that deals with living things. It is broadly divided into zoology, the study of animal life, and botany, the study of plant life. Subdivisions of each of these sciences include cytology (the study of cells), histology (the study of tissues), anatomy or morphology, physiology, and embryology (the study of the embryonic development of an individual animal or plant). Also included in biological studies are the sciences of genetics, evolution, paleontology, and taxonomy or systematic, the study of classification.

Botany: the scientific study of plant life. As a branch of biology, it is also sometimes referred to as plant science(s) or plant biology. Botany covers a wide range of scientific disciplines that study the growth, reproduction, metabolism, development, diseases, and evolution of plants.

Genetics: scientific study of the mechanism of heredity. While Gregor Mendel first presented his findings on the statistical laws governing the transmission of certain traits from generation to generation in 1856, it was not until the discovery and detailed study of the chromosome and the gene in the 20th cent that scientists found the physical basis of hereditary characteristics.

Zoology: The original branches of zoology established in the late 19th century such as zoo-physics, bionomics have largely been subsumed into more broad areas of biology which include studies of mechanisms common to both plants and animals.

Chemistry: the science of matter and its interactions with energy and itself (see physics, biology). Because of the diversity of matter, which is mostly in the form of atoms, chemists often study how atoms interact to form molecules and how molecules(分子) interact with each other.

Physics: the science of Nature in the broadest sense. Physicists study the behavior and properties of matter in a wide variety of contexts, ranging from the sub-nuclear particles from which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology宇宙论).

The Chinese scientist, Yuan Longping, is a _1_ figure in the rice-growing world. When he was educated in school he was given the _2_ , “the student who asks questions”. From an early age he was so interested in plants that he _3_agriculture in college. As a young teacher he began experimenting in crop breeding. First Yuan Longping _4_ with different types of rice. The results became known in China in 1966. Then he _5_ his search for a special type of rice plant. It had to be male. It had to be sterile. Finally, in 1970 a _6_sterile male rice plant was discovered. This was the breakthrough. As a _7 _of Yuan Longping’s discoveries Chinese rice production rose by 47.5 percent in the 1990’s. There were other _8_, too. 50 thousand square kilometers of rice fields were converted to growing _9_and other cash crops. Following this, Yuan Longping’s rice was exported to other _10_, such as Pakistan and the Philippines.
