3.In  earliest times,men  considered  lightning to be  one of the  great  mysteries of  nature.Some ancient peoples believed that lightning and thunder were the weapons of the gods.
In  reality,lightning is a flow of  electricity  formed high above the earth.A single  flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs.
The  American  scientist and statesman,Benjamin  Franklin,was the first to show the connection between electricity and lightning  in 1752.In  the  same  year  he  also  built  the  first lightning rod(避雷針).This device protects buildings from being damaged by lightning.
Modern science has discovered that one stroke of lightning has a voltage(電壓)of more than 15 million  volts.A flash of  lightning between a cloud and the earth may be as long as 13 kilometers,and travel at a speed of 30 million meters per second.
Scientists judge that there are about 2,000 million flashes of lightning per year.Lightning hits the Empire State  Building in New York City 30 to 48 times  a  year.In the United States alone it kills an average of one person every day.
The safest place to be in case of an electrical storm is in a closed car.Outside,one shoud go to low ground and  not  get  under a tree.Also,one should  stay out  of water  and away  from  metal fences.Inside a  house,people  should avoid  open  doorways  and windows  and not touch  wires or metal things.
With lightning,it is better to be safe than sorry.

31.People once thought lightning came fromB.
A.the sky             B.the gods          C.the earth            D.nature
32.According to the passage what do you think all buildings need?C
A.Metal fences.B.Electricity.C.lightning rods.D.Machines.
33.Lightning can travelD.
A.a(chǎn)s quickly as water
B.not so quickly as electricity
C.a(chǎn)t very low speed

34.Which of the following is NOT true?C
A.In the U.S.a(chǎn)bout 360people die from lightning in a year.
B.The Empire State Building frequently gets hit by lightning.
C.Swimming during a thunder storm is a good idea.

A.useful              B.kind             C.useless             D.friendly.

12.DNuclear power is the world's largest source of clean energy.Nuclear power plants(電廠) produce no controlled air pollutants,such as sulfur or greenhouse gases.The use of nuclear power in place of other energy sources helps to keep the air clean,preserve the earth's climate,and prevent acid rain.Howeve r,there exist safety concerns if the plant is not operated correctly or unforeseen things happened when the plant was developed,as happened at the Fukishima(福島) plant in Japan.It may cause damage to everything,including our health.Nuclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.It can't be seen or heard,or touched or tasted,even though it may be all around us.There are other things like that.For example,radio waves are all around us but we can't detect them,sense them,without a radio receiver.Similarly,we can't sense radioactivity without a radiation detector.But unlike common radio waves,nuclear radiation is not harmless to human beings and other living things.At very high levels,radiation can kill an animal or human being immediately by killing masses of cells in vital organs.But even the lowest levels can do serious damage.There is no levels of radiation that is completely safe.If the radiation does not hit anything important,the damage may not be serious.This is the case when only a few cells are hit,and if they are killed immediately.Your body will replace the dead cells with healthy ones.But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble.They reproduce themselves in a deformed way.They can grow into cancer.Sometimes this does not show up for many years.This is another reason for some of the mystery about nuclear radiation.Serious damage can be done without the victim being aware at the time that damage has occurred.A person can be irradiated(輻射)and feel fine,then die for cancer five,ten,or twenty years later as a result.Or a child can be born weak as a result of radiation absorbed by its grandparents.Radiation can hurt us.We must know the truth.

32.What can we infer from the passage?D
A.We can't detect radioactivity even with modern equipment.
B.Only radiation at very high levels can kill an animal or human being.
C.If a few cells are only damaged,healthy cells will take the place of dead ones.
D.Radiation is harmful no matter what level it is.
33.How can nuclear radiation kill an animal?A
A.By killing many cells in important organs.
B.By killing a few cells.
C.By hitting any place in its body.
D.By damaging its heart.
34.If a human being is hit by nuclear radiation,he mayD
A.die of cancer after many years                        
B.die immediately  
C.have a child who may be born weak                   
D.a(chǎn)ll of the above
35.What's the author's main purpose in writing this passage?B
A.Discussing the cause of cancer.
B.Solving the mystery about radiation.
C.Emphasizing the importance of protection from radiation.
D.Introducing the nuclear power.
