The modern combine harvester, or simply combine, is a versatile machine designed to efficiently harvest a variety of grain crops. The name derives from its combining four separate harvesting operations - reaping, threshing [脱粒], gathering, and winnowing [去壳] - into a single process. When a cereal such as corn, wheat, or rice is threshed, it is beaten in order to separate the grains from the rest of the plant. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, corn (maize), sorghum, soybeans, flax (linseed) [亚麻。linen: 亚麻布], sunflowers and canola [芥花/油菜籽]. The separated straw, left lying on the field, comprises the stems and any remaining leaves of the crop with limited nutrients left in it: the straw is then either chopped, spread on the field and ploughed back in or baled [打包。不是bail] for bedding [sth soft for animals to sleep on] and limited-feed for livestock. Combine harvesters are one of the most economically important labour saving inventions, significantly reducing the fraction of the population engaged in agriculture.

Infant formula, baby formula or just formula or baby milk, infant milk, false milk, or first milk, is a manufactured food designed and marketed for feeding to babies and infants under 12 months of age, usually prepared for bottle-feeding or cup-feeding from powder or liquid. The U.S. Federal Food, Drug, and Cosmetic Act defines infant formula as "a food which purports [claim] to be or is represented for special dietary use solely as a food for infants by reason of its simulation of human milk or its suitability as a complete or partial substitute for human milk".

A corporate group or group of companies is a collection of parent and subsidiary corporations that function as a single economic entity through a common source of control. The concept of a group is frequently used in tax law, accounting and (less frequently) company law to attribute the rights and duties of one member of the group to another or the whole. If the corporations are engaged in entirely different businesses, the group is called a conglomerate. The forming of corporate groups usually involves consolidation via mergers [合并。没有“者”] and acquisitions, although the group concept focuses on the instances in which the merged and acquired corporate entities remain in existence rather than the instances in which they are dissolved by the parent. The group may be owned by a holding company which may have no actual operations.
