1,About 1,000 participants in the study filled out a daily diary of their exercise,and then the numbers were crunched by researchers led by David Nieman of Appalachian State University in North Carolina.
“the numbers”是指这些记录的数据吗,“crunched”是咬碎的意思,但在这里可以理解成细细研究吗
“by researchers led by David Nieman of Appalachian State University in North Carolina.”被研究人员,由David Nieman of Appalachian State University in North Carolina领导的研究人员们吗,“led by David Nieman of Appalachian State University in North Carolina”都是补充说明researchers吗,表示是由 David 领导的研究人员吗,这属于什么从句啊,可以在researchers后加that吗,
2,"We found that the most important lifestyle factor in predicting the number of sick days during the winter and fall was the amount of physical activity," he said in a telephone interview.
我们发现最重要的生活方式因素在预测秋季冬季生病的天数是那些做运动的人总数?
这句话怎么理解呢
number of 就是表示生病的天数码,作用就是特指生病的总天数吗,不加也是可以的吗
3,People [who] put in those bouts,five days a week during the 12-week period,had more than a 40-percent reduction in sick days.
bouts是指“bouts of 20 minutes or more一次二十多分钟的运动吗”put in 可以表示参加吗
4,The reduction factored in other data,such as study participants' diet,weight,education,and gender.
factored在这里怎么用的啊,作动词吗
There's been lots of research over the years concluding that physically active people are less likely to have serious conditions,such as heart disease.Now,a new study indicates that those who engage in frequent aerobic exercise are also less likely to catch cold or have other respiratory symptoms.
About 1,000 participants in the study filled out a daily diary of their exercise,and then the numbers were crunched by researchers led by David Nieman of Appalachian State University in North Carolina.
"We found that the most important lifestyle factor in predicting the number of sick days during the winter and fall was the amount of physical activity," he said in a telephone interview.
Specifically,aerobic physical activity,bouts of 20 minutes or more,enough to increase the heart rate and break a sweat.
"People [who] put in those bouts,five days a week during the 12-week period,had more than a 40-percent reduction in sick days."
The reduction factored in other data,such as study participants' diet,weight,education,and gender.
Five weekly aerobic sessions of about 20 minutes each seemed to produce the best results.Those who exercised less frequently were more likely to catch cold.
Nieman says the explanation comes from what happens to certain white blood cells [Neutrophils and natural killer cells] when the body kicks into exercise mode:these immune cells start roaming the blood stream,looking for invaders,such as the viruses that cause colds and other respiratory infections.

1.是的,我也是这样去理解.Researchers后面接的是它的补语,补充说明.
2.不加不可以的,因为这属于作者的意思,你省略了就是改了他的意思.
这个句子可以这样理在预测秋冬季人们生病的天数时,人们的运动量起着很重要的作用（会对这个数字的预测有很重要的影响）.
3.可以的,A bout of activity is a short time when you put all your effort and energy into doing something.通常都是指短时间里大量或剧烈运动.
4.对,作动词,句子中只有这个能做动词,这样才构能得成一个句子.
重在大家一起思考.

对不起，我也不知道！不用谢了！
