Earth is the third planet from the sun.It is one of the four inner planets.The other three inner planets are Mercury,Venus,and Mars.The inner planets are also called the rocky planets,because they are made of rocks.
Earth is often called the “Water Planet”,because it is the only planet in our solar system which has liquid water on its surface.About 70% of the surface of Earth is covered by water! The other part of Earth is made up of continents and islands which have different landforms on them.Examples of landforms are mountains and plains.Plants and animals can live on Earth,because it has so much water.
Earth spins very quickly compared to other planets.It only takes Earth 24 hours to spin around its axis one time.One Earth day is 24 hours long!Earth orbits the sun in 365 days! This makes one Earth year 365 days long!
Earth is the only planet in our solar system where humans,other animals,and plants can live.There is plenty of water to drink or to live in.Water is present on Earth in its big oceans and in the air! Clouds are made of water vapor.The atmosphere has a lot of oxygen in it for animals to breathe,but the rest of our “air” is made up of water vapor,nitrogen,carbon dioxide,and other gases.The air is perfect for plants to grow.Earth temperature is not the same in all places,but the temperature is just right for plants,animals,and humans in most places on Earth.
Like the other inner planets,Earth has volcanoes.Volcanoes on Earth are different from those on other planets,because they still erupt.Scientists think that there may be active volcanoes on other planets and moons in our solar system,but they are still studying this.
Earth has one planet which we call the Moon.The surface of the Moon has many craters on it These were caused when meteorites hit it.It has many volcanoes on it which do not erupt anymore.We can see the moon at night without using a telescope.It is the closest space object to our planet,Earth.
73.Earth is called the Water Planet,______.
A.because animals need water
B.the water makes it look blue from space
C.it has liquid water on its surface
D.Earth is the third planet from the sun
74It takes Earth ______to orbit the sun in one year.
A.24 hours B.24 days C.365 days D.360 days
75Life exists on Earth,______.
A.because the water,air,and temperature are just right
B.there is water vapor in clouds
C.Earth is the planet closest to the sun
D.earth has volcanoes

Humans have observed and explored the oceans since ancient times.But it wasn’t until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S. Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury’s time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today’s oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans.
70.Which of the following statements is true?
A.Humans didn’t explore the oceans until the 19th century.
B.Maury first established the field of oceanography.
C.Maury spent a lot of time in studying seawater,sea life,and the bottom of the ocean.
D.Many individuals also plays a very important part in advancing our understanding of oceans,such as Maury.
71.How many expeditions are mentioned in this passage?
A.Four. B.Three. C.Five. D.Two.
72.What can we infer from the passage?
A.The process of the oceanography has stopped at one time.
B.Maury’s work on oceanography contributes a lot to weather reporting at sea.
C.Nowadays the equipment for studying the oceans needs improving,because it is out of date.
D.The expeditions in the past had great difficulty and made a lot of efforts in order to study the oceans.

If women are mercilessly exploited(剥削) year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion,they are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is capable of standing in front of a wardrobe(衣柜) packed full of clothes and announcing sadly that she has nothing to wear.
Changing fashions are nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who cannot afford to throw away clothing in this way,waste hours of their time altering the dresses they have.Skirts are lengthened or shortened;neck-lines are lowered or raised,and so on.No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth,comfort and durability(耐用).They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort,as long as they look right.There can hardly be a man who hasn’t at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day,or delicately picking her way through deep snow in high-heeled shoes.
When comparing men and women in the matter of fashion,the conclusions to be drawn are obvious.Do the constantly changing fashions of women’s clothes,one wonders,reflect basic qualities of inconstancy and instability?Men are too clever to let themselves be cheated by fashion designers.Do their unchanging styles of dress reflect basic qualities of stability and reliability?That is for you to decide.
66.Designers and big stores always make money .
A.by mercilessly exploiting women workers in the clothing industry
B.because they are capable of predicting new fashions

67.To the writer,the fact that women change their old-fashioned dresses is seen as .
A.a waste of money
B.a waste of time
C.an expression of taste
D.an expression of creativity
68.The writer would be less critical if fashion designers placed more stress on the of clothing.
A.cost B.appearance
C.comfort D.suitability
69.According to the passage,which of the following statements is TRUE?
A.New fashions in clothing are created for the commercial exploitation of women.
B.The constant changes in women’s clothing reflect their strength of character.
C.The fashion industry makes an important contribution to society.
D.Fashion designs should not be encouraged since they are only welcomed by women.

The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(层)just under the surface.The outside dead layers wear off(磨损)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.
The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.
61.Which of the following statements is NOT true?
A.Our hair and nails are dead like the surface of the skin.
B.There is skin all over our body.
C.The skin of our bodies will be completely different in three weeks.
D.The surface of the skin is made of a living layer.
62.The second paragraph mainly tells us about______.
A.the functions of the skin
B.the information from the outside
C.the water in the body
D.the temperature of the body
63.Bacteria will get in through the skin______.
A.when one’s skin is numb
B.when one is ill
C.when the skin is cut
D.when the sweat glands produce more sweat
64.When the weather is cold,the skin will contract in order to______.
A.allow more blood near B.make the skin look blue
C.keep warmth D.help the body lose heat
65.The colour of the skin is determined by______.
A.the rays of the strong sun B.colour cells
C.top layers of the skin D.vitamin D

第三部分：阅读理解（共20小题; 每小题2分,满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
I felt encouraged by his words and began to swim more calmly.But my clothes stuck to me like a heavy weight.I could hardly stay above the surface.
Counsel saw this.“Shall I cut them?”he asked.
With a knife he cut my clothes from top to bottom and took them of quickly while I swam for both of us.Then I did the same for Counsel,and we continued to swim near each other.
But we were in serious trouble.The crew（船员）might not have noticed our disappearance.
And if they had,they could not return because the rudder（舵）had broken.Counsel thought of all this,and calmly made his plans.We decided to wait for the ship as long as possible,because we had no other hope of safety.I suggested that we save our strength so that both of us would not be tired out at the same time.This was how we did it:While one of us lay on his back,quite still,with arms crossed and legs stretched out（伸直）,the other would swim and push him along.We changed every ten minutes or so.In this way we could swim for hours,perhaps till daylight.The crash（破裂声）of the ship and the whale（鲸）had appeared at about eleven o’clock.We had about eight hours to swim before daylight.This seemed possible,if the sea remained calm.
56.What happened to the man who told the story?
A.He and his companion got into the water to test their strength.
B.He jumped into the water to save the broken rudder.
C.He was knocked into the water by his enemy.

57.Why did the two men cut their clothes?
A.Because no people helped them to take off their clothes.
B.Because they couldn’t take off their clothes on the sea.
C.Because they wanted to get rid of their clothes quickly.
D.Because they wanted to lifebuoys（救生圈）with their clothes.
