Although Henry Ford's name is closely associated with the concept of mass production, he should receive equal credit for introducing labor practices as early as 1913 that would be considered67 even by today's standards.Safety 68 were improved, and the work day was 69 to eight hours, compared with the ten-or-twelve-hour day common at the time.In order to accommodate the shorter work day,the 70 factory was converted from two to three 71 .
72 , sick leaves as well as improved medical care for those injured 73 the job were instituted. The Ford Motor Company was one of the first factories to develop a 74 school to train specialized skilled laborers and an English language school for immigrants. Some 75 were even made to hire the handicapped and provide jobs for former convicts（服刑囚犯）.
The most 76 acclaimed innovation was the five-dollar-a-day minimum wage that was 77in order to recruit and 78 the best mechanics and to 79 the growth of labor unions. Ford explained the new wage policy in 80 of efficiency and profit sharing. He also mentioned the fact that his employees would be able to purchase the automobiles that they produced-in effect 81 a market for the product. In order to quality for the minimum wage, an employee had to establish a decent home and 82 good personal habits,including sobriety,thriftiness,industriousness,and dependability.83 some criticism was directed at Ford for involving himself too much in the 84 lives of his employees, there can be no doubt that, at a time when immigrants were being taken 85 of in frightful ways, Henry Ford was helping many people to 86 themselves in America.

B．Although positive feedback loops are probably the most prevalent way of ensuring that daughter cells remember what kind of cells they are meant to be,there are other ways of reinforcing cell identity. One involves the methylation of DNA．In vertebrate cells, DNA methylation occurs on certain cytosine bases. This covalent modification generally turns off the affected genes by attracting proteins that bind to methylated cytosines and block gene transcription. DNA methylation patterns are passed on to progeny cells by the action of an enzyme that copies the methylation pattern on the parent DNA strand to the daughter DNA strand as it is synthesizeD
C．Another mechanism for inheriting gene expression patterns involves the modification of histones. When a cell replicates its DNA,each daughter double helix receives half of its parent’s histone proteins, which contain the covalent modifications that were present on the parent chromosom
E．Enzymes responsible for these modifications may bind to the parental histones and confer the same modifications to the new histones nearby. It has been proposed that this cycle of modification helps reestablish. the pattern of chromatin structure found in the parent chromosome
D．Because all of these cell-memory mechanisms transmit patterns of gene expression from parent to daughter cell without altering the actual nucleotide sequence of the DNA,they are considered to be forms of epigenetic inheritanc
E．These mechanisms, which work together, play an important part in maintaining patterns of gene expression, allowing transient signals from the environment to be remembered by our cells—a fact that has important implications for understanding how cells operate and how they malfunction in diseas
