But these are not analogous to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself----it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves----well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

任务配置：L0+L1+L4

知识笔记：

1.朗读（L0）：

*be not analogous to 不可与......类比

*wear-wore-worn v.穿

worn adj.磨损

*run-down adj.老旧的（外力破坏）

old adj.老得不能用的（经过时间的打磨）

*mend v 修复

*consist of 包含

*living parts有生命的部分

*friction n.摩擦

*be worth doing值得做

2.音标（L1）：

*/j/:yard,yet,you,yes,young,year

*发音技巧：

/j/的发音类似汉语拼音“i”与“e”的连音。

发此音时，双唇微开，舌尖轻轻抵住下牙龈，舌头中间的部位翘起，振动声带。

练习感悟：

1.不练不知道，原来/ɪ/这么难发。昨天练习的那几个和/ɪ/相关的单词，练习几遍之后感觉有点顺口了，但今天碰到了新的组合，又感觉自己不会了。果然还是要多练习，才能真正地掌握这个音标啊！
