U20 lesson 3 Scientific Breakthroughs

If you had to choose the single most important 1___________(discover) of the 20th century, you would have a real 2_________ on your hands. In just 100 years, the world changed completely. Amazing discoveries were made in medicine, communications and transport, not to 3____________ our knowledge of the world and space. Medical advances 4________ from discovering the causes of diseases under microscopes to surgical procedures 5____________(replace) 6__________(disease) organs with 7________ (donate) ones. Communications changed 8______ the introduction of mobile phones and the way we 9__________(通信) went 10________ writing letters to emailing. We started flying around the world and 11____________（同时）, scientists figured 12________ how to 13______(劈开) the atom, 14________（过去）thought to be the smallest particle of matter in the universe.

Although it is impossible to choose the most important discovery, it is possible to 15_________ out a few pioneers of the 20th century. Here are five of them.

One of the 20th century’s premier 16__________ (science) was Albert Einstein. In the summer of 1905, this 17__________(直言的) young man was 18_______(rock) his one-year-old baby when he was suddenly 19_________ (inspiration). “E=mc2” was born. E=mc2 showed how a small piece of 20_______(物质) could produce an 21_________ (believable) amount of energy. Einstein then showed in his “theory of relativity” that not even time, mass or length are 22__________（不变的）– they change according to our experience of them.

Einstein had already become world-famous when a young ex-lawyer, returning from the First World War, started work in California. Using the most high-powered telescope of the time, he began the long, slow process of exploring our galaxy.

E dwin Hubble 23_____ about to make astronomy’s greatest breakthrough of the century. He discovered small areas of mist which were in fact galaxies 24_______ our own, millions of light years away from us, 25__________ proved that the universe was vastly larger than had previously been thought.

in 1929, another far-reaching finding was made by the son of a Scottish shepherd. Before he went 26_____ holiday,27 ________ (biology)Alexander Fleming left a dish with bacteria in it in his laboratory. When he came back, he noticed something strange. He double-28________(check) and saw a blue 29________ in the dish around which the bacteria had been destroyed. This blue mould was in fact the natural form of penicillin, which Fleming realised could be used to kill bacteria.

A few years later, penicillin was 30__________ mass-produced and helping to save the lives of millions. Fleming remained 31_______ about the amazing outcome of his discovery. “Nature made penicillin,” he said, “I just found it.”

During the Second World War, when Fleming’s discovery was first helping to cure people, the US Navy was looking for ways of 32__________ (improve) the accuracy of their missiles. The navy turned ___ Eckert, an engineer, and Mauchly, a 33_______ (physics), to wrestle 34______ the problem and produce a machine to do the job. Although they only finished after the war in 1946, it did not matter. This huge machine was the world’s first computer, but it was nothing like our computers today. It 35_________ (measure) 100 feet long by over 10 feet high and weighed over 30 tones. With 18,000 tubes, thousands of circuits and 6,000 switches, it used so much energy that when it was turned on, the lights in the local town went 36_______ !

These pioneers of the 20th century were all 37____________ to 38_______ (improve) the quality of human life on earth, but sometimes breakthrough discoveries that have affected our lives today happened by 39_______! For example, we are all 40________(感激的) for the handy microwave oven that allows us to prepare meals in minutes and we have Percy Spencer to thank. This inventor, with 120 patents 41____ his name, discovered microwaves when he was experimenting 42______ radars and noticed a chocolate 43________ (melt) in his pocket.

There is no 44_______ about it. 45_________ the breakthroughs of these pioneers in science and technology, whether lucky or planned, the world as we know it today would have been a 46__________ (complete) different place.

Unit19 Language L3课文填空练习

L3 Body Language

If you saw a father 1___________（pat）his son 2________ the back _3_________ smiling happily, what would you think was 4__________ on? You would probably think that the father was 5____________________ his son on 6_______ (do) something well, maybe passing an exam or winning a race. You would know what was going on because you understood the message 7_____________ by the father’s body language. 8___________ the world, a pat on the back and a smile usually means,” Well done”.

Body language is used every single day by people of different 9______________ (nation) all over the world. It is a language without words that 10____________ of gestures, facial expressions and body movements that greatly add to----and sometimes even replace----spoken language. Body language is used to 11_________________(交流) both attitudes and feelings from 12______________(喜爱) to anger just like any other language, but it 13____________ (区别) from spoken language as it is not always 14____________ （清楚的，明确的）. Somebody 15____________ (jump) for joy is easy to see while a 16___________ (raise) eyebrow 16__________ (convey) doubt is easier to miss.

People often use body language 17__________ purpose. Someone who dose not know the answer to a question will move their shoulders 18________________ away from their upper body and then let them fall, 19______________(mean), “I don’t know”. However, body language can be 20_________________ (conscious) as well .A person who is feeling uncomfortable or nervous will often hold their body in a very rigid manner and have a tight look about their mouths. They might also cross their arms and move in an abrupt way 21______________ (resemble) a robot more than a human. They might not even realize how they are acting but their body language will tell anyone who cares to look closely enough ho they are feeling. Body language can therefore make people’s feelings more 22__________________(透明的) as although we can lie with words，it is not as easy to do so with our bodies .

23______________ (Learn) to be 24_____________ of your body language can be a very useful tool. Forexample, in a job interview, you will probably be feeling nervous but you won’t want to appear to be in a stay of_25___________(不安的). You will want to appear calm with as much 26___________（尊严）as possible. 27___________(仅仅) by uncrossing your arms, you will look more confident.

Body language can be very useful when people do not share a common spoken language. For example, in foreign countries, it is very easy to 28________(购买) something simply by smiling and pointing at what you want. On the other hand, you can also easily show 29________you don’t like by shaking your head. You can negotiate the price by 30_____(use) your fingers and even ask questions by using your hands to outline the shapes of things you want—although this can cause confusion and a few laughs too!

However, body language can sometimes be 31_____________(模棱两可的) .Although every culture around the world uses the same gestures and 32___________ （表情）, they use them in different ways. For example, an American tourist at a German hotel might give an “OK”sign by 33___________ (make) a circle with his fingers. 34______________ in American where this sign means everything is fine, in German, this gesture can cause 35____________. Another example is 36________ in most cultures to nod one’s head means “no” while in some cultures the 37__________is true!

38_______________ of these differences, experts agree that across the globe there is one form of body language that receives universal 39______________(approve) —the smile. Smiling has a high 40________ (succeed) rate so never be afraid to use it—even when you’re nervous—and especially in foreign countries!

Lesson 1 Super Athletes

100 metres in 8 seconds?

Many contemporary amateur athletes would＿＿＿＿＿＿world records if they ＿＿＿＿＿＿＿the first Olympic Games. Since then, records ＿＿＿＿＿＿＿track and field ＿＿＿＿＿＿＿as athletic performances ＿＿＿＿＿＿＿.

If records fall, it is usually ＿＿＿＿＿＿＿better equipment, training and diet, but recently, improvements have begun to ＿＿＿＿＿＿＿. At the 2000 Olympics, only three runners achieved Olympic bests ＿＿＿＿＿＿＿. Some experts predict ＿＿＿＿＿＿＿many events, such as 9.5 seconds for the 100 metres – Maurice Greene's current record is 9.79 seconds. However, past predictions ＿＿＿＿＿＿＿.

When ＿＿＿＿＿＿＿breaking records, we come ＿＿＿＿＿＿＿the issue of performance-enhancing drugs. These drugs are originally developed to help people with illnesses, but ＿＿＿＿＿＿＿, they create supreme athletes making them faster and stronger than is normal for human beings. Taking these drugs ＿＿＿＿＿＿＿“doping” and although they enhance performance, they also cause serious health problems in later life for ＿＿＿＿＿＿＿abuse them.

The sports world does not ＿＿＿＿＿＿＿as it is a fundamental form of cheating. Ben Johnson would still be the 100 metres world record holder if he ＿＿＿＿＿＿＿taking drugs in the 1988 Olympics. Other records remain doubtful, like Florence Griffith's 100 metres record back in 1988.

Did she take drugs? If American athlete Marion Jones ＿＿＿＿＿＿＿drugs, would she have ＿＿＿＿＿＿＿the Olympics at all?

Doping is not only a problem in athletics, it is part of every sport where athletes seek to achieve ＿＿＿＿＿＿＿and are prepared to cheat to do so. In 2006 cycling fans worldwide were shocked when the winner of the annual cycling race, the Tour de France, was ＿＿＿＿＿＿＿. Floyd Landis made several lame excuses blaming medicine he had been taking for an injury but these were ＿＿＿＿＿＿＿. He failed two drug tests.

Unfortunately, it is not easy to ＿＿＿＿＿＿＿illegal drugs. It is compulsory for winners to be tested but other participants are only tested＿＿＿＿＿＿＿. New drugs are developed all the time and drug tests for sporting events are often ＿＿＿＿＿＿＿.

Howeve r, doping is not the only thing we need to worry about. Unless we are careful, “gene-therapy” will be the next big threat. For medical purposes, scientists have already found ways to build muscle and increase strength by ＿＿＿＿＿＿＿. Gene-therapy is very controversial and many people oppose further research ＿＿＿＿＿＿＿it. If gene-therapy ＿＿＿＿＿＿＿now, it would be almost impossible to find out. In the future, athletes who have their genes changed might be able to do the 100 metres dash in just 8 seconds or the marathon in less than two hours. However, if a generation of sports stars with enhanced genes were created, it would contradict ＿＿＿＿＿＿＿.

The Olympic spirit — the spirit of competition which emphasises＿＿＿＿＿＿＿— has been violated by the desire to succeed ＿＿＿＿＿＿＿. In today's world, winners are celebrated and treated as heroes, but if doping and gene-therapy continue to affect the outcomes of major sporting events, the word “hero” will have lost all meaning.
