A study of more than five million books, both fiction and non-fiction, has found a marked decline in the use of emotional words over time. The researchers form the University of Bristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise.
They found that almost all of the categories showed a drop in these “mood words” over time. Only in the category of fear was there an increase in usage.
“It is a steady and continuous decrease,” said Dr Alberto Acerbi. He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape. “One thing could be that in parallel to books the 20th century saw the start of other media. Maybe these media — movies, radio, drama, had more emotional content than books.”
Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour：the ratio (比率) between the two varied greatly, apparently mirroring historical events.
During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash. But the ratio plunged at the height of the Second World War. Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends. In the paper, they even argue that the reverse could be true.
“It has been suggested, for example, that it was the suppression (压抑) of desire in ordinary Elizabethan English life that increased demand for writing ‘filled with romance and sex’… perhaps,” they conclude, “songs and books may not reflect the real population any more than catwalk models reflect the average body.”

Maybe you have ever seen a cross. A cross can be a piece of jewelry or an image in
a painting. But do 
you know the cross is a very popular symbol for Christmas？
It came from the story of Jesus’ death on the cross two thousand years ago in Jerusalem. Jesus was Jewish，and at that time Jewish people were under Roman rule. Jesus was badly punished because he declared to be the Son of God and the King of Jews. Surely，the Son of God could have saved himself from the deat
h！But the Bible says that Jesus had a reason to die that day. It was in God’s purpose that it would happen.
Christians call the day that Jesus died “Good Friday”.At first，it is hard to understand how a terrible day could ever be called good. Well，the story does not end there. Jesus died and he was buried. But three days later，Jesus was alive，and the whole world was changed.
Today，Christians everywhere remember this important time. They celebrate Easter. Easter is the day that Jesus rose from the dead. After his death on the cross，Jesus’ body was placed in a tomb. On the third day from then，God raised him from the dead. Jesus stayed on earth physically for several weeks. Many people saw him. Easter is the happiest time of year for Christians because they believe that Jesus had victory over death and evil and that now he lives with God the Father in heaven. But before celebrating Easter， Good Friday should be remembered. Jesus died a horrible and painful death. He suffered, though he did noting wrong. Christian believe that Jesus was God’s substitute(代表) for humans， because humans all do wrong. He died because of humans and he died for humans.
Christians often wear crossed around their necks of hang them in their homes because they believe it is a very important sign. The cross helps them rem
ember how much God loves them. It helps them remember how much his Son had to suffer. Seeing a cross always makes them think of Jesus’
death， and what it means.According to the bible， why Jesus could not save himself from death that day？

Sean and Danielle were leaving the music s
tore when they heard the crash. "What do you suppose that was?" asked Sean.
"I don't know for sure," said Danielle, "but it sure sounded bad. It's right over there. Let's go and look."
Sean and Danielle knew they would see an accident. But they didn't know what to expect. There in the middle of the street was a bicycle that had been hit by a car. The bicycle rider was sitting in the street, shaking his head.
"Look at that," said Sean, "he's not even wearing a helmet. He is one lucky guy".
"No kidding," Danielle replied. "Look at the driver of the car. She's just as lucky. She's not wearing a seat belt.
Sean and Danielle are right. The bicycle rider is very lucky, he was not hurt. Riding a bicycle is a lot of fun, but it can also be very dangerous. You have to pay attention all the time to what you're doing. You also have to follow safety rules.
When you ride a bicycle, remember that you share the road with cars and trucks. These vehicles are a lot bigger than you are. So, always wear a helmet when riding your bicycle. Always means "every time" even if you are just riding around the block.
Follow the same rules as car and truck drivers. Bicycle riders also have some special rules. Here are some special rules you should follow:
● Do not ride your bicycle on the sidewalk. By not riding on the sidewalk, you won't run into a pedestrian.
● Ride on bike paths or trails when they are available.
● Always ride in the same direction as traffic.
● Always ride on the right-hand side of the road.
● Wh
en you ride with a friend, do not ride next to each other. Ride in single field, one behind the other.
● Obey all traffic signals and signs. Stop at all stop signs.
● Walk your bicycle across busy crossings.
● Be sure to use hand signals when you turn and stop.
Follow
these safety rules when riding a bicycle at night.
● Have a headlight that works.
● Have these r
eflectors on your bicycle: yellow or white in front, and red ones on the pedals and back.
● Wear light-colored clothing so drivers can see you.
You should always keep your bicycle in good working order. Make sure the brakes work properly and that your tires have enough air. If you find anything wrong with your bike, fix it or have it fixed before you ride it again.How did Sean and Danielle know that they would see an accident?

Short and shy,Ben Saunders was the last kid in his class picked for any sports team.
“Football,tennis,cricket—anything with a round ball,I was useless,”he says now with a laugh.But back then he was the object of jokes in school gym classes in England’s rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him.At first the teen went biking alone in a nearby forest.Then he began to cycle along with a runner friend.Gradually,
Saunders set his mind on building up his body,increasing his speed,strength and endurance.At age 18,he ran his first marathon.
The following year,he met John Ridgway,who became famous in the 1960s for rowing an open boat across the Atlantic Ocean.Saunders was hired as an instructor at Ridgway’s School of Adventure in Scotland,where he learned about the older man’s cold-water exploits.Intrigued,
Saunders read all he could about Arctic explorers and North Pole expeditions,then decided that this would be his future.
Journeys to the Pole aren’t the usual holidays for British country boys,and many people dismissed his dream as fantasy.“John Ridgway was one of the few who didn’t say,’You are completely crazy,’” Saunders says.
In 2001,after becoming a skilled skier,Saunders started his first long-distance 
expedition toward the North Pole.He suffered frostbite,had a close encounter with a polar bear and pushed his body to the limit.
Saunders has since become the youngest person to ski alone to the North Pole,and he’s skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Saunders, 27,heads south to explore from the coast of Antarctica to the South Pole and back ,an 1800 mile journey that has never been completed on skis. The turning point in Saunders’ life came when__________.
| A．he started to play ball games | B．he got a mounta in bike at age 15 |
| C．he ran his first marathon at age 18 | D．he started to receive Ridgway’s training |
We can learn from the text that Ridgway__________.
A .dismissed Saunders’ dream as fantasy B. built up his body together with Saunders
C hired Saunders for his cold-water experience
D .won his fame for his voyage across the Atlantic.What do we know about Saunders?
| A．He once worked at a school in Scotland. |
B．He fol lowed Ridgway to explore the North Pole. |
| C．He was chosen for the school sports team as a kid. |
| D．He was the first Briton to ski alone to the North Pole. |

| A．was accompanied by his old playmates | B．set a record in the North Pole expedition |
| C．was supported by other Arctic explorers | D．made him well-known in the 1960s |
Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day’s work.
Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open 
air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛).
Ability(能力) to sleep is large lay habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(药）should never be taken except when suggested by a doctor. How many hours are usually enough for the health of a pupil?
| A．Less than eight hours. | B．No more than eight hours. |
| C．Eight hours or so. | D．No less than eight hours. |
What does “sound sleep” mean?
| A．Long sleep. | B．Fast sleep. | C．Complete sleep. | D．Sleep without any sound. |
Which of the following is helpful to good sleep?
| A．Keeping good habits. | B．Staying up late night. |
| C．Eating something at bedtime. | D．Forming the habit of taking sleep-producing drug. |
The amount of sleep a person needs has something to do with________.
| A．his age | B．his height | C．his weight | D．his character |
Before going to bed, you’d better not_______.
| A．take a bath | B．do any housework | C．think a lot | D．go out for relaxation |
The ocean bottom，a region nearly 2.5 times greater than the total land area of the Earth， is even today largely unexplored. Until about a century ago，the deep-ocean floor was completely inaccessible and hidden beneath waters averaging over 3，600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface，the deep-ocean bottom is a strange environment to humans，in some ways as forbidding and remote as the outer space.
Although researchers have taken samples of deep-ocean rocks for over a 
century，the first detailed global study of the ocean bottom did not actually start until 1968，with the beginning of the National Science Foundation's Deep Sea Drilling Project ( DSDP). Using techniques first developed for the offshore oil and gas industry，the DSDP's drill ship，the Glomar Challenger，was able to maintain a steady position on the ocean's surface and drill in very deep
waters，taking samples of rock from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year-research program that ende
d in November 1983. During this time，it sailed 600，000 kilometers and took almost
20，000samples of rocks around the world. Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what 
it will probably look like millions of years in the future. Today，largely on the strength of evidence gathered during the Glomar Challenger's voyages，nearly all earth scientists agree on the theories of plate tectonics (构造学) and continental drift that explains many of the geological processes.
The samples of rocks drilled by the Glomar Challenger have also provided a climatic record stretching back hundreds of millions of years. The information of
past climatic changes can be used to predict future climates. The underlined word" inaccessible" in Line 3 means .
| A．unrecognizable | B．unreachable | C．unusable | D．unreasonable |
Why does the author mention "outer space" in the first paragraph?
| A．The Earth's climate millions of years ago was similar to that in outer space. |
| B．It is similar to the ocean floor in being strange to the humans. |
| C．Rock formations in outer space are similar to those found on the ocean floor. |
| D．Techniques used by scientists to explore outer space were similar to those used in ocean exploration. |
Which of the following is TRUE of the Glomar Challenger?
| A．It is a type of submarine. | B．It is an ongoing project. |
| C．It has gone on over 100 voyages. | D．It made its first DSDP voyage in 1968. |
The Deep Sea Drilling Project was significant because it was .
| A．an attempt to find new sources of oil and gas |
| B．the first extensive exploration of the ocean bottom |
| C．made up of geologists from all over the world |
| D．supported entirely by the gas and oil industry |
