第三步：析难句表达升级

1.Although it has been proved that Franklin’s experiment took place， more than one scientist has questioned what really happened.

句式分析：本句为主从复合句。Although it has been proved that Franklin’s experiment took place为Although引导的　让步状语　从句，该从句中it为　形式主语　，that Franklin’s experiment took place为　真正的主语　；what really happened为what引导的　宾语　从句。

自主翻译：　虽然已证实富兰克林的这一实验确有其事，不少科学家还是对事实真相提出了质疑。　

2.But in science， facts should be proved by experiments and research， and we should not always believe everything we read or hear — even if it is a great story.

句式分析：本句为并列复合句。第二个and之前的分句为简单句；之后的分句为复合句，we read or hear为省略关系代词　that　的　定语　从句，修饰先行词　everything　；even if it is a great story为even if引导的　让步状语　从句。

自主翻译：　但在科学领域，能被实验与研究所证明的东西才算作事实，我们不应全盘相信我们读到或听到的事——即使它是一个精彩的故事。

第一步：拓思维品质提升

If you could change one thing about Franklin’s experiment to make it both safe and able to prove that lightning is a form of electricity， what would you do and explain your reasons？

　I would set up a camera and some sensors near the kite and the key. The sensors can detect the electricity， and the camera can record the whole process. I would stay in a safe place far away and control the experiment with a remote device. This can prove the result of the experiment without putting myself in danger.
