Have you ever rubbed your hands together when they get cold Why do we do that We do
that for friction.Friction happens when two things that aren't smooth(光滑的)rub together to
make heat energy.The faster you rub two things together,the more friction you can make.Let's
discover friction!WHAT YOU'LL NEED:
★Soap ★Water ★Your hands
WHAT TO DO:

★Rub your hands together until you feel the heat of your hands.
★Now,use soap and water to get your hands very slippery(滑的).
★Try to make friction happen while your hands are slippery.
★Please write down what has happened.
LET'S TALK!
★Friction is an energy that happens when two things rub together.When friction happens,it makes heat!When your hands are slippery,they won't make very much friction and your hands
won't get so hot
DID YOU KNOW
★Friction happens when you stop your fast running bike.
★Ancient people made a fire by rubbing two pieces of wood together.Friction happened though
they didn't know it.

ter a short drive to see how much warmer they get from friction.

Butterflies are common all over the world,but butterflies in hotter countries are usually bigger
and more brightly coloured than those cooler countries,and there are more different kinds.
Usually the male(雄性的)butterflies are more brightly coloured than the females.The females have bigger and heavier bodies since they carry the eggs.The bright colours of the males help to at- tract the females,and the duller(较暗淡的)colours of the females make them less likely(可能的)to
be caught by enemies before they have laid their eggs.
Some butterflies have bright pattern colours on the upper surface of their wings that show when flying,but when they rest on a tree or leaves,they close their wings.On the undersides of their wings there are green and brown marks which look like the tree or leaves.They are then diffi- cult to be seen.The best example of this is the Dead Leaf Butterfly.When its wings are closed,it looks exactly like a dead leaf.There are even marks that look like the holes in a dead leaf.When the
butterfly is run after by a bird,it closes its wings and seems to have disappeared completely.
Many butterflies have round marks on their wings that look like eyes.The round marks have a useful function(功能).When the butterflies are resting,their wings are closed,and these marks can't be seen.When a bird sees one,and begins to attack it,the butterfly will open its wings.The
bird thinks that it sees two eyes staring at it,frightened,and flies away.
( )31.The female butterflies have bigger and heavier bodies than the males because
A.the females carry the eggs B.the females eat more
C.the males are more active D.the males have smaller wings
( )32.The duller colours of the female butterflies
A.help to fly easily B.help to attract the males
C.make them look fearful D.make them harder to be caught
( )33.The underlined word"that"in Paragraph 3 refers to

C.green leaves D.some butterflies
( )34.When the Dead Leaf Butterfly is run after by a bird,it
A.is frightened and flies away at once
B.opens its eyes and stares at the bird
C.closes its wings and seems to have gone
D.opens its wings to frighten the bird away

C.what the round marks look like D.what the function of the round marks is

Do you know about DNA Here is an introduction of it.
DNA is short for deoxyribonucleic acid.It contains genetic instructions.These instructions are used in the development and functioning of all known living organisms(有机体).That's to say that your DNA decides what you are like.Perhaps this is a little bit difficult for you to understand.Here is an example to explain it more clearly.Before you were born,your DNA had already decided you would have two hands and that each hand would have five fingers.Your hands would help you hold
things and do many other things.
However,DNA is more than that.We get our DNA from our father and mother.That is why we look like our parents and are not like others.Also because of different DNA,Chinese people look different from Americans.We have black hair and eyes,but many Americans have blue eyes and blond hair.Though we have discussed many things about DNA here,there is still a lot more to
know about it.If you would like to know more about DNA,you can go on the Internet.

V. 词语运用(共10小题，每小题1分，计10分)
根据短文内容及所给提示，在文中的空白处填写一个正确的单词。
Last Wednesday,my classmate Jenny and I did an experiment.First,we prepared two glasses. One glass was 41. (fill)with fresh water,while the other with salt water.Second,we chose two eggs of the same 42. (weigh)and put them into the glasses at the same time. Guess what 43. (happen) The egg in the glass with fresh water sank while the other one floated.Why We looked 44.t the Internet and found the correct answer.The reason is that the density(密度)of the salt water is greater than 45. of the fresh water.Just like in
the Dead Sea,there is no fish at all,but a man who can't swim will certainly float without
46. (sink).This is really an unforgettable experiment to both 47 us.From the experiment I know science is very fantastic.Scientific 48. (discover)are amazing,too.With the 49. (develop)of science,our lives will become better and better.I must work hard at
science 50.t it is hard to learn.I want to be a scientist when I grow up.
