正确答案:
1. fetal sleep
3. blood glucose
4. time of day
5. cigarette smoking
解释 :
The fetus does go through sleep cycles, rendering it less likely to move while it is asleep. Blood glucose does cross the placenta and can affect fetal movement. Cigarette smoking causes carbon monoxide to cross the placenta, which reduces fetal oxygen. Pregnant women are more likely to notice fetal movement while they are sitting or lying down, and time of day often determines this. Most pregnant women notice fetal movement in the evening. Barometric pressure does not affect fetal activity in utero.
