Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization.
n.
可变性,反复不定
n.
一般化,概况,归纳
Just how much exercise a person of a given age can safely take 是由how引导的主语从句,can take 是谓语,how much exercise 是宾语。
to answer 是动词不定式短语,修饰 hard。to permit of generalization 动词不定式短语作结果状语
一个一定年龄的人到底做多少运动才是安全的?这是一个难以回答的问题。个人的变易性太大,不能一概而论。
It has been demonstrated experimentally that the epidemic common cold is caused by a filterable virus. The influenza virus may cause symptoms quite indistinguishable from a common cold. This leads to the suggestion that commom cold is a symptomatic response of the respiratory tract to the virus and not a clinical or etiologic entity
n.
过滤性病毒
adj.
无法区分的,无法识别的
n.
实体
that the epidemic common cold is caused by a filterable virus从属连词that引导的主语从句作主语,has been demonstrated 是谓语。
that commom cold is a symptomatic response 是that 引导的同位于从句,to the virus 作定语。
实验曾经证明流行的普通感冒是由滤过性病毒引起的。流感病毒可引起与普通感冒很难区别的症状,这就使人们认为普通感冒是呼吸道对病毒的一种症状性反应,而不是临床上或病原学上的独立疾病。
