请根据句意及所给汉语提示完成下列各题: 1.他站起来把一些酒到进我的玻璃杯里   He stood up and ___

玻璃杯里有一定质量的酒精,酒精的深度为10cm,酒精重2.4N,已知玻璃杯重0.6N, 杯底~

解:(1)杯底受压力=2.4N (酒精的重力)
杯底受压强= 2.4N /(20/10000 m2) =1200 N/m2
(2) 桌面受压力=2.4N+ 0.6N= 3.0N
桌面受压强= 3.0N/ (20/10000 m2)= 1500 N/m2

1 P=ρgh=800*10*0.1=800Pa F=ps=1.6N
2 F=3N P=F/s=1500Pa

1.poured; into
2.is lost
3.There; climbing
第二题不可用is missed 因为miss 做丢失这个意思用的话是不及物动词,不及物动词是没有被动语态的,而 lose 做丢失讲的话就是及物动词,相应的被动语态为 is lost。
这个句子还可以是  Helen's English book missed/is missing.

1 He stood up and(spread)some wine (in) my glass.
2 Helen's English book (is) (missed), She is looking for it now.
3 Look! (There) is a cat (climbing) the tree over there.

poured some wine into my glass
helen's English book is missing
look, there is a cat climbing the tree over there.
