Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb new concepts，and display higher levels of concentration.
Professor Anne Bamford，of the University of the Arts，London，studied the effectiveness of 3D content in 15 schools across seven countries，including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks，improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding，increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology90 percent of those in the study had seen a 3D film.Schools would need 3Denabled projectors(投影仪)，laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson，an educationist，said the technology would be impractical to use inschools and could be costly.He said，“While I think the idea of 3D technology is very interesting，I worry that 3D is a bit of an expensive gimmick(小玩意儿)．There are a few cases where a true3D image might help，but most of the time，good 2D models that can be moved would be just aseffective.”
In the US，one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.What is the main idea of the first three paragraphs?
| A．There are slight differences between 3D and 2D images. |
| B．Pupils perform better when 3D images are used in classes. |
| C．Schools have difficulties in making full use of 3D technology. |
| D．3D technology is always more effective than 2D technology. |
Danny Nicholson holds the view that 3D ________.
| A．is of no help in classes |
| B．has a bright future in classes |
| C．is more practical than 2D models |
| D．may not be affordable for schools |
What can we learn from the last paragraph?
| A．3D technology will replace 2D models in the future. |
| B．Many pupils are now more Interested In science than before. |
| C．Teachers will use the 3D technology through specific training. |
| D．3D will soon be put into use in one school district in Colorado. |

Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.
The first is called the " tank(贮水池) test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode (爆炸)in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.
The most dangerous test happens when the new plane is going through test flights in the air. The pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.By doing the "tank test", the engineers can find out _______.
| A．the amount of air in the plane | B．the strength of the plane structure |
| C．the pressure inside and outside the plane | D．the power of the airplane engines |
What will happen to the plane under the "tank test"?
| A．It will be broken. | B．It will be made stronger. |
| C．It will be filled with water. | D．It will be tested by pilots, |
According to the text, why are test flights most dangerous?
| A．The plane may explode in the air. | B．The pilot may lose control of the plane. |
| C．The engines may be damaged. | D．Too much air may get into the plane. |
What might be the most suitable title for the text?
| A．Two Important Tests on Airplanes | B．The Importance of Flying Safely |
| C．The Danger of Testing Airplanes | D．How Airplanes Are Made and Tested |
There is an English saying that “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter can really improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has the same effects as physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effects of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated（忍耐）the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress(压力) and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics（诊所）, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.According to the passage, the following statements are true except.
| A．Laughter is good for health | B．Laughter can make you become old quickly |
| C．Laughter helps to reduce pain. | |
| D．Laughter, just like physical exercise, is good for our body. |
The underlined word “diminishes” in the third paragraph means “”.
| A．enjoys | B．permits | C．increases | D．reduces |
According to the author, we should .
| A．laugh as much as possible | B．watch more funny films |
| C．avoid smiling all the time | D．spend more time in laughter clinics |
The best title for this passage may be .
| A．Both laughter and physical exercise are good for health |
| B．Laughter clinics help patients improve their condition |
| C．Laughter can reduce the effects of pain |
| D．Laughter is the best medicine. |
The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.
The fire started on Sunday morning in the house of the King's baker(面包师)in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery(面包房)into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.
Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect(建筑师), wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them new St Paul's.

People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues（线索）that will help them or someone else to find it again.
In Britain a few years ago, a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.
One of the most popular adventure stories ever written is Robert Louis Stephenson's “Treasured Island”, an exciting story about a young boy, Jim Hawkins, who is captured by pirates (海盗) and later finds some buried treasure.
Then there is the true story about a man who had to travel overseas for a year. He did not trust banks, so he buried his life savings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.
And then there was the man who buried his savings, all in bank notes, in a waterproof（防水的）bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.
And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.
Although it is true that people sometimes lose their money because a bank fails, banks are still the safest place to keep our savings and treasures. People who bury treasure usually.
| A．do not trust banks |
