Directions:

There are four reading passages in this part.Each passage is followed by five questions.For each question there are four suggested answers marked A, B, C and D.Choose one best answer and blacken the corresponding letter on the Answer Sheet.Passage One

In the old days, divers used to go down into the sea looking for ships that had sunk, because they hoped to find gold and jewels.Now divers still search for valuable things in sunken ships, but they also try to bring to the surface the ships themselves, or parts of them.The value of different kinds of metals has increased greatly over the last twenty or thirty years and even though a ship has been under the sea for many years, it may be worth a great deal.One famous sunken ship is the “Lusitania”, which sank off the southern coast of Ireland in 1915 with a loss of nearly, 1,500 lives.It has four huge propellers made of an expensive metal.Today each of those propellers is worth $ 300,000 or more.The ship lying on the sea-bed has been brought by a man called John Light.He paid about $ 1,200,000 for the whole ship.He hopes to bring up those propellers and sell them.He also hopes to sell other parts of the ship, when he has brought them to the surface, for about $ 600,000.61.Divers today try to bring to the surface _______.A.gold and jewels

B.parts of ships

C.whole ships

D.all of the above

62.Diver try to bring up metals because ________.they have been in the sea for a long time

gold and jewels are not valuable things

some kinds of metals are worth a lot of money

it is easy to bring up metals

63.The word “surface” in the passage means the ______.D.sea

64.John Light hopes that he may be able to sell all the parts of the “Lusitania” for about _____.D.$1,800,000

65.John Light bought the “Lusitania” _______.A.before 1915

B.before it sank

C.after it sank

D.after they had brought up the propellers

Passage Two

Man’s first real invention, and one of the most important inventions in history, was the wheel.All transportation and every machine in the world depend on it.The wheel is the simplest yet perhaps the most remarkable of all inventions, because there are no wheels in nature—no living thing was ever created with wheels.How, then, did man come to invent the wheel? Perhaps some early hunters found that they could roll the carcass of a heavy animal through the forest on logs more easily than they could carry it.However, the logs themselves weighed a lot.It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick.This would roll along just as the logs did, yet be much lighter and easier to handle.Thus the wheel and axle came into being and with them the first carts.66.The wheel is important because _______.A.it was man’s first real invention

B.all transportation depends on it

C.every machine depends on it

D.both B and C 67.The wheel is called _______.A.simple

B.complicated

C.strange

D.unusual

68.It was remarkable of man to invent the wheel because _______.A.it led to many other inventions

B.man had no use for it then

C.there were no wheels in nature

D.all of the above

69.The wheel was probably invented by ______.A.a group of early hunters

B.the first men on earth

C.a great prehistoric thinker

D.the man who made the first cart

70.This selection says that the first wheel may have been a ______.A.round piece of stone

B.heavy log

C.piece of metal

D.slice

A.market

B.air

C.top of a liquid

A.$12,000

B.$300,000

C.$1,200,000

of log

Passage Three

Eating in space is different from eating on earth.The food that astronauts carry with them does not look like the food you eat.Some food is carried in closed bags.It is cooked and frozen before the astronauts get it.All the water is removed from the food.In the spaceship the astronaut puts the water back.He “shoots” hot or cold water into the food bag with a special gun.He eats the food through a small hole in the bag.Other foods come in bite sizes.The astronaut puts a whole piece in his mouth at once.There an be no crambs.Crambs would float around the spaceship and get in the way.Meat and cake often come in bite-sized pieces.Astronauts can’t drink water from open cups.The water would float in drops in the air.The water is put in the special gun.The astronaut shoots the water into his mouth.Eating in space is not easy.Astronauts must learn to eat this way.71.Some space foods are carried in _______.A.water guns

B.lunch boxes

C.closed bags

D.crumbs

72.The story does not say this, but from what we have read, we can tell that ______.A.you get much hungrier in space than you do B.you can’t have water to drink in a spaceship

C.astronauts must learn many new and different things D.you can’t eat anything in a spaceship 73.Why can’t astronauts drink water from cups? A.The water would come from the open cups.B.The water would spill all over their food.C.Crambs would float in the cups.D.The cups would float in the air.74.The main idea of the whole story is that _______.A.there is more food and water in space than on earth B.eating and drinking in space is a special problem C.astronauts can never eat or drink in a spaceship D.there is no food or water in a spaceship

75.Which of the following does the story lead you to believe? A.Food for astronauts must be made in a special way.B.All meat on earth comes in bite-sized pieces.C.Astronauts will only eat cakes made from crambs.D.Astronauts have to go hungry in a spaceship.Passage Four

The energy which the sun radiates goes in every direction, and only a minute part of it falls on the earth.Even so, it represents power of about 5,000,000 horsepower(馬力)per square mile per day;the sun gives us as much energy every miunte as mankind utilizes in a year.At present, we use this energy indirectly, and it is our final source of power.Coal represents the chemical action of the sun on green plants thousands of years ago.Water power results from the rain formed by vapor which comes from the evaporation of water under the sunshine.Even windmills operate because of air currents set in motion by the different heating affects of the sun in different places.Some day, through chemistry or some type of solar engine, we shall harness this great source of energy more directly.Already a scientist has worked out an engine, surprisingly efficient, in which the sun’s rays are concentrated through mirrors on a tube of water to create steam.76.How much energy given off by the sun reaches the earth?

A.100% but indirectly.B.5%.C.50%.D.only a very tiny amount.77.The reason why all the solar energy falling on the earth can’t be utilized is that ______.A.only a very small part is available B.the sun is too distant from the earth

C.it takes thousands of years for this energy to be stored up in coal and oil D.our scientific knowledge is not sufficient 78.Which of the following statements is NOT true? A.Even windmill’s action depends on the sun.B.The sun produces enormous energy for man to make use of.C.Some day man will be able to utilize 100% of the solar energy that gets to the earth.D.The sun produces different heating effects in different places.79.In order to support this argument, the writer gives the example that _______.A.a machine using solar energy efficiently has already been developed B.the sun is our final source of power C.man uses only a tiny part of the sun’s energy D.the part of the sun’s energy we use is used indirectly 80.This passage centers mainly on ________.A.harnessing energy through chemistry B.our last source of power

C.how water power is produced

D.the amount of solar energy that can be utilized

解 limf(x0?h)?f(x0)hh?0?limf(x0?h)?f(x0)?hh?0?(?1)??f?(x0)?2.選(B).22..當(dāng)x?0時(shí), x與sinx比較是（）.(A).較高階的無窮小

(B).較低階的無窮小

(C).同階但不等價(jià)的無窮小

(D).等價(jià)的無窮小

分析 先求兩個(gè)無窮小之比的極限,再做出正確選項(xiàng).解 因lim2x2x?0sinx?limxsinxx?0?x?0,故選(A).3.設(shè)曲線y?x?x?2在點(diǎn)M處的切線斜率為3,則點(diǎn)M的坐標(biāo)為()

(A).1(,0)

(B).?(1,0)

(C).2(,4)

(D).(-2,0)解 由y??2x?1?3知x?1, 又y

三、計(jì)算題 1.計(jì)算limx?arctanxln(1?x)3x?1?0,故選(A).分析 屬00型未定式,利用等價(jià)無窮小代換,洛必達(dá)法則等求之.x?0解 limx?arctanxln(1?x)x22x?03?limx?arctanxx31??limx?011?x23x2
