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 1
VOYAGE 2
Mark’s finger flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED.
START TRANSPORT PROGRAM.
AUTO-RETRIEVE INITIATED(自动回收程序已启动).”
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

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(气象学者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud(积云). 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(悬浮的) 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(略微调高) 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.
【小题1】The weight of is NOT mentioned in the passage.
A.a cumulus cloud | B.a tornado |
C.a hurricane | D.a storm cloud |
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. |
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. |
A.How Much a Cloud Weighs | B.How Much a Hurricane Weighs |
C.Surprising Results | D.Elephants in the Sky |

At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.
There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.
During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract(紧缩) several muscles in your arm, which are connected to your fingers by tendons(腱);as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons(爪) close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.
【小题1】Bats hang upside down because________.
A.they haven’t developed a pair of strong claws |
B.they can’t start to fly from the ground directly |
C.they have no hind legs to support their body |
D.they can’t find quiet places to stay during the day |
A.is to save their energy for night movement |
B.is a way to fight against flying animals |
C.is a great way to hide from danger |
D.is a skill to compete for the flying places |
A.Because their upper body is light. |
B.Because they have strong muscles. |
C.Because their talons are linked to muscles tightly. |
D.Because their tendons are linked to their upper body. |
A.The living habits of bats. |
B.How and why bats hang upside down. |
C.The importance of bats’ hanging upside down. |
D.How bats use their energy at night. |

Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory(呼吸系统)and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.
China needs to develop its economy and invest(投资) in high-tech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's resolution to address the environment issue.
【小题1】The effect of smog doesn’t include.
A.the rising of PM 2.5 readings |
B.more people suffering diseases |
C.the increase of people’s income |
D.patients increased in hospital |
A.Because people have to pay higher prices. |
B.Because nobody can avoid it. |
C.Because we have to develop industry. |
D.Because a popular online-post discussed it. |
A.human beings | B.other plants |
C.space technologies | D.industrial development |
A.high-tech can completely solve the problem of pollution |
B.space technologies should be developed in a large scale |
C.we can move to the Mars after the earth has been destroyed |
D.we must protect the environment while developing economy |

We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.
【小题1】What has the new study of more than 260,000 people found?
A.Sugary sodas aren’t good for the physical health of old people. |
B.Americans have a special tooth for sweet foods. |
C.Sweetened soft-drinks may increase the risk of depression. |
D.Sweetened soft-drinks have important physical consequences. |
A.About twenty-six thousand people participated in it. |
B.The oldest participants were below 80 when the study was over. |
C.Most of the participants had depression when the study was over. |
D.The study lasted more than ten years from the beginning to the end. |
A.can reduce the harm of sweetened drinks |
B.is used to reduce the risk of depression |
C.is mainly used to make fruit punch |
D.is used to make something .sweet |
A.more research is needed to confirm the new findings |
B.the new findings aren’t consistent with any previous findings |
C.cutting one’s sodas intake will surely reduce one’s depression |
D.the new findings won’t have an impact on people’s drinking habits |
A.Sodas. |
B.Unsweetened coffee. |
C.Sugary coffee. |
D.Fruit punch. |

Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation(感觉)of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.
Psychologists have known that one person’s perception(感知)of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.
Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.
To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses(假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form. The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.
“We are grounded in our physical experiences even when we think abstractly,” says Bargh.
【小题1】The author mentions Harlow’s experiment to show that ________.
A.babies need warm physical contact |

A.Drinking for Better Social Relationships. |
B.Developing Better Drinking Habits. |

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
【小题1】55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?
A.The whole world becomes extremely cold |
B.All the coastal cities in Africa are destroyed |
C.The visit of the comet results in wars |
D.The whole mankind becomes extinct |
A.Because they could only live in the warm climate |
B.Because their extinction indicates future disasters |
C.Because they once dominated the earth |
D.Because dinosaurs and humans never live in the same age |
A.give an accurate description of the possible disaster in the future |
B.prove that humans will sooner or later be destroyed |
C.warn of a possible disaster in the future |
D.tell the historical development of the Earth |
A.article of popular science | B.news report |
C.research paper | D.horror story |

Scotland is a unique place, loaded with history, where you can find aristocratic(贵族的)palaces and castles, as well as the traditional parades in national costumes.
In order to see and discover the true soul of Scotland today and what formed the character of this splendid region, we have to go towards the northern regions, to the Grampian Mountains(格兰扁山区), beautiful and plain. The Scots conquered the environment with simple spades and strong arms, for it was difficult to farm.
The history of this ancient struggle, and its people’s ancient love with the hard land, can be felt within the walls of the Angus Folk Museum. You are able to get a feel of the typical rural atmosphere of times past from the everyday artifacts displayed here.
From coastal Aberdeen in towards the Grampian Mountains there runs the Castle Trail, a road that touches on many fortresses(堡垒), which are witnesses of continual fights against the control of neighboring England in Scottish history.
Perhaps the most exciting moment for Scottish autonomy is the one experienced inside this ancient church of Arbroath, where, in 1320, the Declaration of Independence was celebrated, at the instigation(鼓动)of King Robert the Bruce. He carried out the plan for autonomy drawn up by the great popular hero William Wallace, for whom cinema has designed the wonderful film Brave Heart, the winner of the five Oscars.
This is Glamis Castle, where King Macbeth and Queen Elizabeth used to live. Among the most frequent guests here are the predictable ghosts, if not actually created, by ancient popular beliefs. These have been handed down over the centuries by people tending to live with mystery, with the forces of the supernatural.
Another attraction here is a legendary monster: the Loch Ness Monster. Whether it’s real or imaginary, this monster, which has been nicknamed Nessie, has collected a good 3,000 sightings over the last 50 years.
The true flag of Scotland, tartan, is recognizable from the brightly colored plaid patterns which are used to distinguish the various social groups.
Bagpipes and dancing open the competitions of local sporting events, which are called Highland Gatherings.
【小题1】Take a look at the Angus Folk Museum, and we can learn about _______. .
A.the love of ancient Scottish to the hard land |
