     It was a Sunday and the heavy storm had lasted all night.The morning after the storm, though, was

beautiful:blue skies, warm air and a calm, inviting sea touching the shore gently.

     My father realised it was a good day for fishing and invited my sister and me to go with him.I was

only 14 and fishing had never been my thing, but I decided to go all the same.I'm_so_glad_I_did.

     On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself

was in fairly good shape.After all, it was protected by the arms of a bay that had only one tiny channel

to the sea.As we got on board, we noticed two big humps(脊背) in the distance.

     On approaching them, we saw it was a mother whale with her baby.We couldn't believe it-there

aren't any whales along the coast here.The storm must have driven them across the ocean into the bay,

in which the still water was so badly polluted that nothing could survive.

     The little baby whale-actually as big as our boat-was obviously stuck and could not move.The mother

dived under the water and came up suddenly, making big whirlpools(漩涡) and waves."She's trying to

help her baby, but on the wrong side, "my father said.At this point, my father moved our boat in a

semicircle to the other side and, heading the boat towards the baby whale, pushed it gently.With our

several gentle pushes the big hump turned over and disappeared under water.Then it swam up right

beside its mum.They struggled in their desperate attempts to escape but missed the exit and started

heading in the wrong direction.We hurried up to the whales and tried to lead them towards the bay

channel.Slowly, they let us lead them, sometimes rising from the water right beside us to breathe-and to

give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight

from the sea, the mum gave us a wave with her tail and off they swam into the distance.

     In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for

almost an hour and a half.That was the simple and lasting beauty of the day.Nearly four decades later, I

still look back fondly to that golden day at sea.

实验题

蕲春实验中学化学课外活动小组选择如下相应的装置对某有机物燃烧产物进行探究,并对该有机物成分进行测定:

         A            B          C               D                E

[提出假设]  根据质量守恒定律,可得出该有机物燃烧产物可能为①CO2、H2O;②H2O、CO;③CO2、H2O、CO。

[设计实验]

(1)余成林同学选择D、E分别验证假设①,如观察到E中                    现象,则证明有H2O,如观察到D中                 现象,则证明有CO2

(2)翁京京同学选择装置A、C、D、E按照E D C A 的连接顺序一次性来验证假设②,实验时发现E中无水CuSO4变蓝,D中澄清石灰水变浑浊,A中黑色CuO变成光亮红色,则假设②是否成立     ,得出这个结论的理由是:                  

(3)汪俊同学同样按照E D C A D的连接顺序来验证假设③,如该假设成立,则丙同学应应观察到____________________________________________现象,那么该实验装置还有何不足:           _______________

(4)现假设该有机物燃烧产物为CO2、H2O,有甲、乙两组同学选择B、C装置分别两种方法测定它的组成,得出两组数据(连接顺序与数据如下表)

 有机物

的质量

装置的连接顺序装置的质量

实验前              实验后

甲组1.6克C接BB  200克            B 202.3克

C  200克            C 201.7克

乙组1.6克B接CB  200克            B 201.8克

C  200克            C 202.2克

你认为甲、乙两小组的两种方法哪种正确?    ,理由是:    _____     。请你选择、计算得出有机物各元素的质量比:
