Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men”, said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
“The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技術(shù)). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(細(xì)胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs ( The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.)
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
【小題1】According to the passage, human death IS now mainly caused by____.

A.diseases and aging B.a(chǎn)ccidents and war
C.a(chǎn)ccidents and aging D.heart disease and war
【小題2】In the author’s opinion, today’s most important advance in technology lies in____.
A.medicine B.the Internet C.brain cells D.human organ
【小題3】Humans may live longer in the future because_____.
A.heart disease will be far away from us
B.human brains can decide the final death
C.the basic materials of cells will last forever
D.human organs can be repaired by new medicine
【小題4】We can learn from the passage that ______.
A.human life will not last more than 120 years in the future
B.humans have to take medicine to build new skin cells now
C.much needs to be done before humans can have a longer life
D.we have already solved the technical problems in building new cells
【小題5】What will people in 2113 mainly die of /from?
A.Aging B.Accidents C.Cancer D.Heart disease

In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes(性別) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神經(jīng)) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(創(chuàng)造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller number of nerves than the two sides of a woman’s brain are.
【小題1】Which of the following is the best title of the article?

A.Research on the Brain
B.Men and Women are Different in Brain
C.People’s Different Brains
D.Who Are Better, Boys or Girls
【小題2】__________ men and women think differently.
A.The different brains make
B.Sex makes
C.The different experiences make

In the late 1970’s,many people in North America turned their attention to environmental problems ,and new steel — and — glass skyscrapers were widely criticized. Some ecologists (生態(tài)學(xué)家)pointed out that a number of tall buildings in a city often overburden public transportation.
Skyscrapers are also lavish consumers of electric power and water. In just one recent year, the addition of 17 million square feet of skyscraper office space in New York City itself has already raised the top daily demand for electricity by 120, 000 kw — enough to supply the entire city of Albany in New York area for a single day.
Glass—walled skyscrapers can also be especially wasteful. The heat loss ,or gain, through a wall of half 一 inch plate glass is more than ten times that through a typical ordinary wall filled with bricks or board. In order to decrease the pressure on heating and air — conditioning equipment, builders of skyscrapers have begun to use double—layered glass ,and reflective glasses coated with silver or gold mirror films that could reduce glare (強(qiáng)光)as well as heat gain. However, mirror — walled skyscrapers may raise the temperature of the surrounding air and affect neighboring buildings as well.
Skyscrapers put a severe pressure on a city's sanitation (衛(wèi)生)facilities, too. If fully occupied, the towers just within the central area of New York would alone produce 2. 25 million gallons of waste water each year^—as much as the city size of Stanford, Connecticut, which has a population of more than 109,000.
【小題1】The underlined phrase“ lavish consumers ”in the 2nd paragraph probably means ____

A.trash producersB.great spendersC.pressure makersD.poor customers
【小題2】Glass walls of skyscrapers are specially mentioned in order to _____.
A.show how skyscrapers manage to lessen their pressure
B.explain why skyscrapers can control its air conditions
C.describe further how wasteful skyscrapers could be
D.present the stability of skyscrapers in modern buildings
【小題3】From the last paragraph we can learn that _____.
A.central New York skyscrapers are a large waste water producer
B.the central area of New York is as large as the city of Stanford
C.more than 109,000 people live in the skyscrapers in New York
D.New York produces 2. 25 million gallons of waste water each year
【小題4】When the writer talks about skyscrapers ,his tone sounds _____

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew. And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch(縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement(侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties(版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
【小題1】Barthelemy Thimonnier’s garment factory was burned down because _____________.

A.people did not know how to put out the fire
B.Elias Howe thought Thimonnier had stolen his invention
C.the sewing machines was couldn’t work finally
D.workers who feared the loss of their jobs to a machine set fire
【小題2】Which of the following is NOT TRUE according to the passage?
A.Singer is an American inventor and manufacturer.
B.The Singer sewing company became more practical.
C.The foot treadle helped to make the sewer’s hands free.
D.Singer made improvements to the design of sewing machines.
【小題3】Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?
A.Because the judge was against Singer for his surly attitude.
B.Because Howe had already patented the lockstitch used by Singer.
C.Because Singer had borrowed money from Howe and never repaid it.
D.Because Singer and Howe had both invented the same machine.
【小題4】Which of the following would be the best title for this passage?
A.Stitch in Time Saves Nine
B.The Case between Howe and Singer
C.Patent Laws on the Sewing Machine
D.The Early History of the Sewing Machine

The octopus’s(章魚)reputation as a human-killer isn’t simply an exaggeration(夸張)—it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish(殼類動物)and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width.
The hard, parrot-like beak(喙)of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these careful creatures to get a good look at them.
【小題1】This passage is mainly about          .

A.the horrors of the octopus
B.the largest octopus in the world
C.octopi and their behavior
D.the octopus’s deadly hunting method
【小題2】It is implied but not stated in the passage that          .
A.people have unreasonable fears about the octopus
B.the octopus is not interested in human beings
C.the octopus is afraid of human beings
D.the octopus is a very cruel sea animal
【小題3】What does the underlined part “careful creatures” refer to in the last paragraph?
A.Octopi.B.Shellfish.C.Fish.D.The victims.
【小題4】The hard beak of the octopus is used for          .
A.a(chǎn)ttacking deep-sea diversB.cutting up large pieces of meat
C.cutting open its victimsD.defending itself
【小題5】From the passage, we can conclude that          .
A.the octopus is not dangerous to man
B.people often fear creatures that are not dangerous to them
C.the octopus only hunts its natural victims
D.things described in movies are not to be believed

Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will "obey" spoken instructions some time before they can speak, though the word "obey" is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But sincethese can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation leads on to deliberate (有意的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
It is a problem we need to get out. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world.Thus the use at seven months of"mama" as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.
【小題1】Before children start speaking, _____. 

A.they need equal amount of listening
B.they need different amounts of listening
C.they are all eager to cooperate with the adults by obeying spoken instructions
D.they can't understand and obey the adult's oral instructions
【小題2】Children who start speaking late _____.
A.may have problems with their listening
B.probably do not hear enough language spoken around them
C.usually pay close attention to what they hear
D.often take a long time in learning to listen properly
【小題3】A baby's first noises are _____.
A.a(chǎn)n expression of his moods and feelings
B.a(chǎn)n early form of language
C.a(chǎn) sign that he means to tell you something
D.a(chǎn)n imitation of the speech of adults
【小題4】The problem of deciding at what point a baby's imitations can be considered as speech _____.
A.is important because words have different meanings for different people
B.is one that should be properly understood because the meaning of words changes with age
C.is not especially important because the changeover takes place gradually
D.is one that should be completely ignored (忽略) because children's use of words is often meaningless
【小題5】The author implies _____.
A.parents can never hope to teach their children new sounds
B.even after they have learnt to speak, children still enjoy imitating
C.children no longer imitate people after they begin to speak
D.children who are good at imitating learn new words more quickly

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:
“ENTER NAMES
VOYAGE。
VOYAGE。
Mark’s finger flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED.
START  TRANSPORT  PROGRAM.
AUTO-RETRIEVE  INITIATED(自動回收程序已啟動).”
The screen turn even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒),until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed:
“TRANSPORT SUCCESSFUL.
DESTINATION:  MARS.
RETRIEVE DATE:  2025
【小題1】Why did Mark touch the computer against his father’s warning?

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(氣象學(xué)者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud(積云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(懸浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant-sized particles(微粒), it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微調(diào)高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
【小題1】The weight of      is NOT mentioned in the passage.

A.a(chǎn) cumulus cloud B.a(chǎn) tornado 
C.a(chǎn) hurricane D.a(chǎn) storm cloud 
【小題2】How did Peggy LeMone feel about the result of her calculations?
A.She found it not convincing. 
B.She thought it needed further calculations. 
C.She was quite surprised at it. 
D.She considered the calculations inaccurate. 
【小題3】What can be inferred from the passage?
A.A storm cloud weighs about 200,000 elephants. 
B.The water in a hurricane weighs more than that in any other kind of cloud. 
C.There are less than forty million elephants living on the earth. 
D.The water in the cloud is in very tiny partials. 
【小題4】What is the best title for the passage?
A.How Much a Cloud Weighs B.How Much a Hurricane Weighs 
C.Surprising Results D.Elephants in the Sky
