The oldest and hardest cow beef may be made as tender and tasty as young and choice met. ”This declaration was made by the French physicist Denis Papin in book published in 1681, which described his “New Digester” or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121℃. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal（密封）—a replaceable rubber sealing ring. When Vischer’s patent（专利）expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests. From the passage we can learn pressure cooker made of cast iron lasted at least ____years.

The Neutrality of American in the Early World War II
The establishment of the Third Reich influenced events in American history by starting a chain of events which culminated in war between Germany and the United States. The compete destruction of democracy, the persecution of Jews, the war on religion, the cruelty and barbarism of the Nazis, and especially the plans of Germany and her allies, Italy and Japan, for world conquest caused great indignation in this country and brought on fear of another world war. While speaking out against Hitler’s atrocities, the American people generally favored isolationist policies and neutrality. The Neutrality Acts of 1935 and 1936 prohibited trade with any belligerents or loans to them. In 1937 the President was empowered to declare an arms embargo in wars between nations at his discretion.
American opinion began to change somewhat after President Roosevelt’s “quarantine the aggressor” speech at Chicago (1937) in which he severely criticized Hitler’s policies. Germany’s seizure of Austria and the Munich Pact for the partition of Czechoslovakia (1938) also aroused the American people. The conquest of Czechoslovakia in March, 1939 was another rude awakening to the menace of the Third Reich. In August, 1939 came the shock of the Nazi-soviet Pact and in September the attack on Poland and the outbreak of European war. The United States attempted to maintain neutrality in spite of sympathy for the democracies arrayed against the Third Reich. The Neutrality Act of 1939 repealed the arms embargo and permitted “cash and carry” exports of arms to belligerent nations. A strong national defense program was begun. A draft act was passed (1940) to strengthen the military services. A Lend Act (1941) authorized the President to sell, exchange, or lend materials to any country deemed necessary by him for the defense of the United States. Help was given to Britain by exchanging certain overage destroyers for the right to establish American bases in British territory in the Western Hemisphere. In August, 1940 President Roosevelt and Prime Minister Churchill met and issued the Atlantic Charter which proclaimed the kind of a world which should be established after the war. In December, 1941, Japan launched the unprovoked attack on the United States at Pearl Harbor. Immediately thereafter, Germany declared war on the United States.One item occurring before 1937 that the author does not mention in his list of actions that alienated the American public was

We Should All Grow Fat and Be Happy
Here’s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn’t eat this and she mustn’t that. Oh, but of course, she doesn’t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it’s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.
What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for ‘health cures’. For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don’t think it’s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God.
Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they’re always hungry. You can’t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood(奇妙的事物) is a complete food, the advertisement says. ‘Just dissolve a teaspoonful in water…’. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they’re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!
What’s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly（saintly<圣洁的>的反义词） people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!The best title for this passage is

Antinuclear Demonstration
Police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted police on the construction site of a 1,000-megawatt nuclear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said, the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.
Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. “This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law,” he said. And police called in reinforcements from all over the state to handle the disturbances.
The protests began before dawn Friday when several thousand demonstrators broke through police lines around the cordoned-off construction site. They carried placards that read “No Nukes is Good Nukes,” “Sun-power, Not Nuclear Power,” and “Stop Private Profits from Public Peril.” They defied police order to move from the area. Tear gas canisters fired by police failed to dislodge the protestors who had come prepared with their own gas masks or facecloths. Finally gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.What were the demonstrators protesting about?
A Private profits. B Nuclear Power Station.
C The project of nuclear power construction. D Public peril.Who had gas-masks?
A Everybody. B A part of the protestors.
C Policemen. D Both B and C.Which of the following was NOT mentioned as a reason for the demonstration?
A Public transportation. B Public peril.
C Pollution. D Disposal of wastes.With whom were the jails and courts overloaded?
A With prisoners. B With arrested demonstrators.
C With criminals. D With protestors.What is the attitude of Governor Stanforth Thumper toward the power project and the demonstration?
A stubborn. B insistent. C insolvable. D remissible.
Superconducting Materials
The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff(超级材料). Material science -- once the least sexy technology – is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.
The key to the new materials is researchers’ increasing ability to manipulate substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.
A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion.
Some advanced materials are old standard with a new twist. The newest fiberoptic(光学纤维的) cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.
But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.How many new materials are mentioned in this passage?
A Two B Three C Four D FiveWhy does the author mention genetic engineering and computer science?
A To compare them with the new materials.
B To show the significance of the new materials on the future world.
C To compare the new materials to them.
D To explain his view point.Why is transition difficult?
A Because transition requires money and time.
B Because many manufacturers are unwilling to change their equipment.
C Because research on new materials is very difficult.
D Because it takes 10 years.Where lies success of a country in the New Age of superstuff?
A It lies in research. B It lies in investment.
C It lies in innovation. D It lies in application.
Everyone has good days and bad days.
Sometimes, you feel as if you’re on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork.
For more than 20 years, scientists have suggested that high self-esteem (自尊) is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something.
“Forget about self-esteem,” says Jennifer Crocker, a psychologist (心理学家) at the University of Michigan, US. “It’s not the important thing.”
Feeling good
Crocker’s advice may sound a bit strange because it is good to feel good about yourself.
Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem.
But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person.
He believes that violent and wicked people often have the highest self-esteem of all. He also said: “There’s no evidence that kids with high self-esteem do better in school.”
Problems
All types of people have problems. People with high self-esteem can have big egos (自我) that can make them less likeable to their peers(同龄人), said Kathleen Vohs, a psychology professor at Columbia University.
People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help.
What to do
Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something try to learn from the experience. “The best therapy (药方) is to recognize your faults,” Vohs says. “It’s OK to say, ‘I’m not so good at that,’ and then move on.”The new research comes to the conclusion that high self-esteem ________.
| A．is not important at all | B．has taken on a different meaning |
| C．may not be the key to success | D．does not help you do better at school |
One of the conclusions of the new research is that ________.
| A．feeling good about oneself doesn’t mean you lead a happier life |
| B．people with high esteem usually do not seek other’s help |
| C．people with high esteem tend to be proud |
| D．people with low esteem are often more popular |
The underlined part “a better person” in the passage probably means a person who is ________.
| A．helpful and supportive | B．gentle and modest |
| C．likable and successful | D．friendly and kind |
From the text, we can infer the best therapy mentioned in the last paragraph is mainly for people ________.
| A．with high self-esteem | B．with low self-esteem |
| C．of all kinds | D．who are focusing on building self-esteem |
