Benjamin Franklin
What made him famus?
Funding Fathers f the USDeclaratin f Indepenceleading authr, printer, publisher, diplmat, scientist and inventr.
Read the shrt intrductin t Benjamin Franklin.
As a scientist, he was a majr figure in the American Enlightenment（启蒙） and the histry f physics fr his discveries and theries regarding electricity. As an inventr, he was knwn fr the lightning rd（避雷针）, and the Franklin stve. He funded many civic（市政的） rganizatins, including the Library Cmpany, Philadelphia's first fire department and the University f Pennsylvania.
What can yu infer frm the essay title?
The essay title is explicit, making it clear that the stry abut Franklin's experiment may be fictinal.
Title:Franklin's Experiment: Hw Much Is True?
1. An egg can bear at least 10kg.
2. Watt invented the steam engine inspired by the jumping lid f a biling kettle.
3. Cut an earthwrm int tw, and yu can get tw living earthwrms.
4. Franklin's kite-in-a-thunderstrm experiment
Nw read the essay and check yur predictin.

Read the para 1-2 and find ut what Franklin’s experiment aimed t prve(1m')
Franklin’s experiment aimed t prve if lightning was really prduced by electricity r smething else.

A kite with a string and a metal key
First, Franklin flew a kite with a string and a metal key. Then, when a flash f lightning hit the kite, electricity was cnducted thrugh the string t the key. Finally, tuching the key, Franklin gt an electric shck.
Lightning was a frm f electricity.
Read the para 3-6 and number the statements t shw hw peple’s attitudes twards Franklin’s experiment have changed.(3m')
Franklin’s spirit f scientific explratin is still cnsidered an inspiratin. Peple are amazed at and inspired by Franklin’s experiment. Scientists questin what really happened in Franklin’s experiment.
Q1:What’s the meaning f“…if Franklin had actually tuched the key, he wuld certainly have died frm the electric shck.”Q2: Thus hw much is true in this experiment?
He didn’t tuch the key.
Flying the kite and the kite was hit by a lightning may have happened, but Franklin didn’t tuch the key.

In rder t find ut whether lightning was really prduced by electricity r smething else, Benjamin Franklin made a kite-in-a thunderstrm experiment. He raised a kite int the sky with a metal key attached t its string. After a flash f lightning hit the kite, Franklin then tuched metal key and gt an electric shck. The experiment prved that lightning was a frm f electricity. Mre than ne generatin f schlchildren have been amazed and inspired by by Frenklin's spirit and bravery fr scientific explratin. Hwever, with time ging by, the details abut the experiment were questined. If Franklin had actually tuched the key, he wuld certainly have died frm the electric shck. Actually, peple have been mre inspired by Franklin's spirit f scientific explratin than by facts themselves. In cnclusin, we shuld nt always believe everything we read r hear-even if it is a great stry.

One day Isaac was reading a bk under an apple tree n the farm. An apple fell ut f the tree - bnk! Ow! Nw, fr mst peple that wuld be the end f the stry, but nt fr Isaac. Nt fr smebdy wh just culdn't stp asking why all the time. Why did the apple fall ut f the tree? Des everything fall? What makes things fall? Can anything stp things frm falling? Are the sun, mn, and stars falling? Why dn't they ever hit the grund? S many questins. Newtn spent many years answering these questins by thinking and ding experiments. He made up the law f gravity. Accrding t this law everything pulled everything else t itself by a frce called gravity. Hw strng that frce is depends n hw heavy the things are and hw clse tgether. S even tw apples pull tward each ther. But, the frce is s small that yu need a very careful experiment t measure it. The reasn that things fall tward the grund is that the earth we live n is s very heavy, and we are s clse t it. Newtn's law f gravity nt nly explained hw things fall n earth, but hw planets mve arund the sun and hw mns mve arund planets.
