生长发育的调查方法主要有几类,他们的含义和特点是什么?

答案

参考答案:

有横断面调查,追踪性调查和半纵向调查。

(1)横断面调查:即在某一较短时间内,在一定的地区范围内,选择有代表性的对象,对某几种项目和指标进行一次大数量调查。其目的是在一个较大地区范围内调查得出某项指标的正常值,可作为该地区少年儿童生长发育的“标准”。

(2)追踪调查:一种动态观察。通过选择较少数量的对象,在一个比较长的时间内进行定期的、连续多次的调查,来观察少年儿童的发育动态。其目的是制定生长速度的正常值;通过对某一发育期全过程的连续观察,揭示生长发育的规律性;系统深入的观察分析某些内外因素对生长发育的长期影响。

(3)半纵向调查:一种横断面和追踪调查两者结合的调查方法。其目的是为了克服追踪调查所需年限太长和观察对象易于流失的缺点而产生的一种设计。

You will probably try harder to get more sleep once you see how much better you feel with even 30 minutes more sleep.

Getting more sleep is sometimes merely a matter of scheduling. In the next couple of weeks, try to get rid of one or two things from your morning and evening routine. If morning is your downfall, shift(转移) some of your morning routines to the night before or putting something off until your break at lunch. If late afternoon and night are your downfalls, do the same.

You don’t really need to watch the news. It’s depressing. If something important happens today, you will find out tomorrow at work. At least skip(略过) the weather. Right after dinner, go to a major search engine, and type in “national weather” and the name of your town. You will see a two-line weather report from the National Weather Service. This will save you several minutes of watching the weather on television.

If reading helps you, take a boring book or magazine to bed with you. Paperbacks(平装本) are not as heavy and are easier to read in bed. 

If you have a partner or roommate, maybe you can take turns with a neck and shoulder massage at night instead of television.

Make sure you are ready for sleep when you go to bed. __________ such as televisions, computers, and video games wake us up. Avoid them for at least an hour before you plan to go to bed.
