why sense of smell changes with age?
谁能找到这方面的知识啊，很简单的就可以。但是要英语的！
感谢了先|！
参考答案:口腔内感受味觉的主要是味蕾，其次是自由神经末梢，婴儿有10000 个味蕾，成人几千个，味蕾数量随年龄的增大而减少，对成为物质的敏感性也降低。
The sense of taste mainly depends on taste bud [味蕾],tnen the nerve ending[神经末梢]. Since taste buds became fewer and fewer with the age,our sense of taste become blunter and blunter. blunt[迟钝]
应该有错的地方,你可以把英文复制下来,然后让大家改错.[单复数就弄不懂,英语真是麻烦]
啊,原来是"smell'呀,搞错了... o O
