你是需要一句话还是两句话?
我需要一点药=I need some medicine.
进入睡眠=fall asleep或go to sleep.
我需要一点药(帮助我)进入睡眠=I need some medicine for sleep或I need some sleepingpills.
I need some medicine to get to sleep.
medicine 可以换做pills,在口语里尤其如此。
如果你写的这是两句话:
I need some medicine.
Fall asleep.
您的标点符号也太.....
I need some medicine(pills)to make me sleep.
I need a little medicine. go to Sleep
I need some medicine. Go to sleep.
