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.

“I will never marry，” the future Elizabeth I declared at the age of eight, and, to the terror of her people, the Great Queen kept her word.
For four centuries, historians have guessed why Elizabeth never married.In her own day, her decision to remain single was considered absurd and dangerous.A queen needed a husband to make political decisions for her and to organise and lead her military campaigns.More important, she needed male heirs to avoid a civil war after her death.
There was no shortage of suitors for the Queen, both English courtiers (朝臣) and foreign princes, and it was confidently expected for the best part of 30 years that Elizabeth would eventually marry one of them.Indeed, although she insisted that she preferred the single state, she kept these suitors in a state of permanent expectation.This was a deliberate policy on the Queen's part, since by keeping foreign princes in hope, sometimes for a decade, she kept them friendly when they might otherwise have made war on her kingdom.
There were, indeed, good political reasons for her avoiding marriage.The disastrous union of her sister Mary I to Philip II of Spain had had an unwelcome foreign influence upon English politics.The English were generally prejudiced against the Queen taking a foreign husband, particularly a Catholic one.Yet if she married an English, jealousy might lead to the separation of the court.
There were other, deeper reasons for Elizabeth's unwillingness to marry, chief of which, I believe, was her fear of losing her autonomy as Queen. In the 16th century, a queen was regarded as holding supreme dominion(统治权)over the state, while a husband was thought to hold supreme dominion over his wife.Elizabeth knew that marriage and motherhood would bring some harm to her power.
She once pointed out that marriage seemed too uncertain a state for her. She had seen several unions in her immediate family break down, including that of her own parents.
Some writers, based on very fragile evidence, have argued that Elizabeth was frightened or incapable of the sex act, but it is more likely that she feared childbirth. Two of her stepmothers, her grandmother and several acquaintances had died in childbed.
Elizabeth's father, Henry VIII, had had her mother, Anne Boleyn, killed; her stepmother Catherine Howard later suffered the same fate. When Elizabeth was 14 she was all but attracted by Admiral Thomas Seymour, who also went to the prison within a year. Witnessing these terrible events at an early age, it has been argued, may have put Elizabeth off marriage.
Elizabeth had to decide her priorities. Marriage or being single? Elizabeth was far too intelligent.The choice she made was courageous and revolutionary, and, in the long run, the right one for England.
1.To the suitors including English courtiers and foreign princes，Elizabeth ________.
A．held back the truth
B．gave a definite answer “no”

There was great excitement on the planet of Venus (金星). Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week's satellite landing，” Prof. Zog said, “that there is no life on Earth.”
“How do you know this？” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned？”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies？”
“Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won't this set back the flying saucer program several years？”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)．” Profession. Zog replied.

This message is to inform all the children that Santa's post office in Himmelpfort, Germany, is open to receive your holiday wishes. That means you can mail your letters to Santa about 6 weeks sooner than that last year. Santa knows you've been good and wants to make sure he and his helpers receive your wish list earlier.
Eight post offices are organized across Germany to answer all letters children send. This year they plan to receive over 250,000 letters. Though the letters fly from over 80 different countries, Santa and his helpers can understand and make sure to answer all the letters.
In 1984, two children from Berlin sent their wish lists to Himmelpfort after spending vacation there. Their letters were answered by postal employees and later Himmelpfort increased its helpers to meet the needs of increased mail traffic. Year after year, Santa and his crew use an ecofriendly powered vehicle to collect the thousands of letters he receives from young boys and girls.

(London)If it really is what's on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn't surely mean you are not fat，” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body's communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle，” Bell said.
1.What is this piece of news mainly about?
A．Thin people also have troubles.
B．Internal fat is of no importance.
C．Internal fat leads to many diseases.
D．Thin people may be fat inside.
2.Doctors have found ________.
A．being slim doesn't mean you are not fat inside
B．internal fat is the cause of heart disease and diabetes
C．being slim is not dangerous at all
D．the exact dangers of internal fat
3.According to the passage, which of the following is WRONG?
A．People with heart disease all have internal fat.
B．People can get rid of internal fat by improving diet.
C．Men are more likely to have too much internal fat.
D．Exercise can help to reduce the internal fat.
