The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet , but two pieces will probably hit the southern half of the Earth .
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere (大气层) with a massive explosion . About half of the piece is destroyed , but the remaining part hits the South Atlantic at 200 times the speed of sound . The sea boils and a huge hole is made in the sea bed . Huge waves are created and spread outwards from the hole . The wall of water , a kilometer high , rushes towards southern Africa at 800 kilometers an hour . Cities on the African coast are totally destroyed and millions of people re drowned .
Before the waves reach South America , the second piece of the comet lands in Argentina . Earthquakes and volcanoes are set off in the Andes Mountains . The shock waves move north into California and all around the Pacific Ocean . The cities of Los Angeles , San Francisco and Tokyo are completely destroyed by earthquakes . Millions of people in the southern half of the earth are already dead, but the north won’t escape for long . Because of the explosions , the sun is hidden by clouds of dust , temperatures around the world fall to almost zero .Crops are ruined . The sun won’t be seen again for many years . Wars break out as countries fight for food . A year later , no more than 10 million people remain alive .
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 piece of object in space . The dinosaurs couldn’t live through the cold climate that followed and they died out . Will we meet the same end ?
小题1:What is mainly described in the passage ?
| A．A historic discovery . | B．An event of imagination |
| C．A research on space . | D．A scientific adventure . |
| A．an earthquake | B．damages to cities |
| C．an Earth explosion | D．huge waves |
| A．Because the land is covered with water |

核心考点
举一反三
This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
小题1:．Why does Virgin Airlines try to replace normal fuel with biofuel?
| A．To cut down the flight cost of the company. |
| B．To remove some hurdles for the biofuel to work. |
| C．To reduce CO2 emissions from airplanes. |
| D．To test plane engines on biofuel. |
A Biofuel cannot run for long flights.
B．Biofuel cannot work at high altitudes.
C．Man has not enough land to grow extra crops for biofuel.
D．It’s not easy for sewage treatment plants to manufacture biofuel.
小题3:．One of the hurdles to be overcome for a full biofuel switch is to .
| A．alter the engine for airplanes |
| B．make biofuel burn consistently |
| C．open more land to grow more crops |
| D．develop sewage treatment plants |
| A．there is a long way to go for a complete switch to alternative fuel |
| B．it won’t be long before alternative fuel comes into use |
| C．airlines, oil companies and airplane manufacturers are reliable |
| D．alternative fuel has a bright future |
| A．Biofuel-Alternative Fuel Sources. |
| B．The First Commercial Flight Powered by Biofuel. |
| C．How to Reduce CO2 Emissions from Airplanes. |
| D．Vigin Airlines Trying to Alter Fuel Sources. |
Let children learn to judge their own work. A child who learns to talk does not learn by being corrected all the time. If corrected too much., he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him. Little by little, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught-to walk, run, climb, whistle, ride a bicycle-compare their performances with those of more skilled people, and slowly make the needed changes.
But in school we never give a child a chance to find out his mistakes and correct them himself. We do it all for his act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says , what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(daily) work? Our job should be to help the children when they tell us that they can’t find the way to get to measure their own understanding, how to know what they know or do not know.
小题1: According to the passage, the best way for children to learn things is by ______.
| A．listening to the advice of grown-ups. |
| B．asking adults many questions. |
| C．making mistakes and having them corrected. |
| D．doing as other people do by themselves. |
| A．Give children correct answers. |
| B．Allow children to make mistakes. |
| C．Tell the children what is wrong with their work as often as possible. |
| D．Let children judge their own work. |
| A．encourage children to learn from each other. |
| B．point out children’s mistakes whenever they are found. |
| C．correct children’s mistakes as much as possible. |
| D．teach children more knowledge from book. |
| A．different from learning other skills. | B．the same as learning other skills. |
| C．more important than other skills. | D．unnecessary skills. |
| A．Let Us Teachers Stop Working. | B．Let Children Alone. |
| C．Let Children Correct Their Exercises. | D．Let Children Learn by Themselves. |

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余项。
What is your favorite color? Do you like yellow, orange, and red? 71 Do you prefer grays and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist（悲观者）. At least, this is what psychologists（心理专家） tell us, and they should know, because they have been seriously studying the meaning of colors preference, as well as the effect that colors have on human beings. 72 If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
73 A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. 74 A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ---until it was repainted green. The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
75 It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.
| A．On the other hand, black is depressing. |
| B．They tells us that we do not choose our favorite color as we grow up——we are born with our preference. |
| C．The rooms are painted in different colors as you like. |
| D．If you do, you must be an optimist（乐观者）, a leader, an active person who enjoys |
E. Light and bright colors make people not only happier but more active.
F. Life is like a picture or a poem, full of different colors.
G. Colors do influence our moods——there is no doubt about it .
We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft no longer exists.
One of the ways these people wrongly support their view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability. “Homes in those days were well-built,” they say. No doubt these homes were well-built, but what these people have done is mix up the quality of material used in the house with the quality of the craftsmanship.
Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, most people can no longer afford solid oak stairways, although they were once fairly common in older homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better job than carpenters of old.
One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and powerplanes help them lay out a house better and make more precision cuts on the wood. Also, it is not uncommon say more to find carpenters with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs.
The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the carpenter of fifty years ago, but only if given proper material.
小题1: Compared to the carpenters in the past, modern carpenters are .
| A．more successful | B．more learned |
| C．more imaginative | D．more hardworking |
| A．Carpenters who are fond of oak stairways. |
| B．Carpenters who have college degrees. |
| C．People who think highly of carpenters of old. |
| D．People who think that modern material is of low quality. |
| A．People in the past preferred to use oak to build stairways. |
| B．It is now expensive to employ a carpenter. |
| C．Modern houses last as long as the old ones. |
| D．Good carpenters still exist in modern times. |
| A．Is Craft Dead? | B．Craft, Back to Life? |
| C．History of Craftsmanship | D．Carpenters Today and Yesterday |
