Ⅳ.阅读理解
Bananas are a good snack. Not only are they sweet and delicious,but they are
easy to take around,so you can take them anywhere. Best of all,bananas provide
（提供） different things that the human body needs!
Bananas grow best in warm places that get lots of rain. They grow on plants
that look like trees. The banana plant,however,is considered a herb（草本） rather
than a tree because it doesn't have a strong,woody stem（茎）.The plants can grow
as high as 30 feet. When they reach their full height,flowers grow out from the
stem. These flowers produce bananas.#2
Two or three times each year,the plants produce fruit. The bananas grow
together,which seem like “hands”.A hand is made up of 10 to 20 bananas. Growers
sometimes call bananas “fingers”.Each bunch（丛） of bananas has about 15
hands,and so a whole bunch may have as many as 200 bananas and can weigh
more than 100 pounds.
After about three months,farmers pick the bananas. At this point,they still aren't
the sunny yellow-coloured bananas. Farmers pick them when they're green. That's
how they're shipped to stores. They turn yellow along the way and are ready to be
sold.
If you love bananas,you've got a lot of company. Americans have been
enjoying bananas since the first shipment arrived in the United States in
1870.Today Americans eat more bananas than any other fruit. More bananas are
sold than apples and grapes together. Every American eats over 26 pounds of
bananas each year!#5
1.The first paragraph mainly talks about ___.
A
A.why people like bananas B.how bananas taste
C.what bananas are rich in D.where bananas are taken
2.The underlined word “it” in Paragraph 2 probably refers to ___.
B
A.bananas B.the banana plant C.herb D.tree
3.［新考法·事件顺序］What is the correct order in which these happen
a. The bananas begin to turn yellow.
b. A banana plant grows to full height.
c. The flowers produce bananas.
d. The bananas are ready to be picked.( )
B
A.c-b-a-d B.b-c-d-a C.b-c-a-d D.c-b-d-a
4.Why do farmers pick bananas when they're green ( )
C
A.Because they are always green.
B.Because people like green bananas.
C.Because it's convenient to ship.
D.Because yellow bananas aren't delicious.

Ⅴ.［培优题］阅读表达
Many people believe sharks are one of the most dangerous animals in the
world. But according to a report,humans bring a far greater danger to sharks than
they do to us. Shark attacks（攻击） do happen. However,they are not very often.
Sharks are in danger. It is time that we should take action to stop many kinds of
sharks from dying out.
Why should we save sharks Because killing sharks is a problem for the whole
world. Sharks are on the top of the food chain. They eat other species（物种）,but
few species eat them. As sharks die off,the number of other species will increase.
This,in turn,means the food that other species eat will become less. So how can
you help save sharks #1.1
Don't use shark products. Pet foods,energy drinks,leather products can be made
from shark parts. And shark meat is sold around the world. Most sharks killed
worldwide are hunted for their fins（鳍）,which are used to make shark fin soup.
Sharks breathe by swimming. So if a shark's fins are cut off,it can't swim and will
die.
If you eat seafood,make sure the food you eat comes from fisheries（渔场）
that care for the sea. Many organizations try to protect sharks. They give us advice
on how to keep them alive.
No buying,no killing!Maybe that is the best way to save sharks.#1.1.3
根据短文内容，回答下列问题。
1.Why should we take action to protect sharks
___________________________
Because they are in danger.
2.What will happen if sharks die off
_________________________________________
The number of other species will increase.
3.Can sharks live without fins Why
________________________________________________________
No. If sharks don't have fins,they can't swim and will die.
4.What do the organizations do to protect sharks
_______________________________________________
They give us advice on how to keep sharks alive.
5.［新考法·开放性设题］What can we do to protect sharks
_________________________________________________________________________
We can stop people buying products from sharks.（开放性设题，答案合理即可）

Blue whales live in the ocean. They are not fish. They have lived on earth for
a long time. The blue whale can grow to 30 metres long and weigh 200 tons—
heavier than 30 elephants!The blue whale is also one of the smartest animals in the
world. They can communicate with each other by using special sounds. But humans

blue whales!

Everyone knows that bees are busy. There is even a saying in English that
one can be “as busy as a bee”.However,little is known about how bees play.
Scientists have found one way that bees could relax after a busy day—they play
with balls.
The scientists are from a university of London. They did different tests on
bees “playing” with different things. They found bees liked playing with
small,wooden（木质的） balls best.
The scientists said the way bees played was a little like how humans play.
Younger bees play with more balls than older bees;older males（雄性） spend
longer playing with balls than older females.#1.2
The scientists took 45 bees to a test place. In this place,the bees had two
ways to choose. The first was to fly or walk directly to get sugar. The second was
to get the sugar by going around different coloured balls. The scientists found that
most of the bees decided to play with the balls first and then get their sugar.
A scientist said the study showed that bees are cleverer than people believed.
She said,“Bees are hundreds of miles far from the mindless. They are not
traditionally believed to be.” She added,“This study shows a strong point that insect
minds are far smarter than we think.”#1.4
根据短文内容，回答下列问题。#2
1.What's the Chinese meaning of “as busy as a bee”
____________
忙得团团转
2.How do bees relax after a busy day
_____________________
They play with balls.
3.What do bees and humans have in common when they play
_________________________________________________________________________

playing with balls than older females.
4.In the study,how did most of the bees get sugar
__________________________________________________________________________
Most of the bees decided to play with the balls first and then get their sugar.
5.What do you learn about bees
___________________________________
