Module 2DNA—the Secret of LifeCurrently there are some 20,000 chemicals in use, but thescientists only have detailed information on around 1,000 ofthem.To see the advantages of GM food you have only toconsider the recent press revelation that the average lettucereceives eleven pesticide applications before it reaches the supermarket shelf.I'm sure chemicals and their roles in disease will become a big issue in the next century as the population of the developed world worries increasingly about its health.The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world's predicted population growth to ten or eleven billion.It's not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we're on the edge of a new revolution: a genetic one.It may well be that in the long term it is the developing world that benefits most from GM foods.It's true that for the next ten years or so GM crops may be too expensive.But the lesson of personal computers is applicable here—once the technology has been developed for money-spinning crops, like maize, soybeans and cotton, it will filter down andbecome affordable for all.This doesn't mean, unfortunately, that famines will disappear, but severity and duration will be helped by an improved ability to produce and distribute food.As we move into this new era of agriculture we're embarking on an experiment.Butremember that the world has seen a number of experiments before.We have been refining species of wheat for several thousand years.Genetic engineers like me are not doing anything as dramatic as making a cabbage into a cauliflower—as has been done by plant breeders in the past.We're simply tapping into the whole gene pool, rather than concentrating on one species at a time.1．According to the passage, we can see that the author has a/an____attitude towards GM food?A．disappointed B．indifferentC．hopeful D．uncertain2．Which of the following statements is wrong?A．Chemicals and their roles in disease will become a big problem in the future.B．In the long term it is the developed world that benefits most from GM foods.C．It's true that for the next ten years or so GM crops may be too expensive.D．Famines will not completely disappear even though GM food become affordable in the future.【答案】 1.C 2.BSection ⅠIntroduction & Reading and Vocabulary(1)—Preparing词义搭配1．Question A．the work of inquiring into somethingthoroughly2．hereditary B．become different；change；make sth.different3．investigation C．ask what happens4．alter D．sth.that follows from an action or set ofconditions5．consequence E．related to the passing of physicalcharacteristics through genes【答案】 1.C 2.E 3.A 4.B 5.D短语填空2．It is said that the cause of the collapse of the bridge is still____________.3．Your son is so stubborn that he doesn't____________you in any way.4．The old newspapers take up too much space, and we'd better______them.5．After a medical consultation, the doctors decided to______________on the patient without delay.6．____________smoking, my father coughs frequently.【答案】 pared with 2.under investigation3．take after 4.get rid of 5.perform an operation6．As a consequence of根据提示补全下列教材原句1．Crick and Watson had found the_answer_to one of the most important questions of biology—how do living things reproduce themselves?克里克和沃森找到了生物学上最重要问题之一——生物是如何复制自己的——的答案。

你知道著名的庞贝古城吗？Historical Background of The Ancient City of PompeiiIn the early afternoon hours of August 24，79 A．D.the summit ofMount Vesuvius exploded without warning.A black river of ash andlapilli ran from the crater of the volcano down through the city of Pompeii leaving death and destruction in its wake.The magnificent ancient city of Pompeii was left buried under about 20 feet of earth and ash.Pompeii was originally only 500 meters from the sea，but after the eruption the distance to the sea increased to two kilometers.Oscans settled along the shore of the Tyrrhenian Sea on an elevated lavic spur that was created by an ancient eruption of Vesuvius during the 8th century B．C.The strategic location made Pompeii an object of great importance to the Estuscans.The Samnites arrived from the mountains of Irpinia in the 5th century，putting an end to the control of Campania by the Greeks and Etruscans.It was inevitable that Pompeii would fall under the domination of Rome at the beginning of the Samnite Wars.Pompeii became a Roman colony in 80 B．C.，taking the name “Colonia Veneria Cornelia Pompeii”which refers to both her conqueror and to the goddess Venus.Seventeen hundred years later，architect Domenico Fontana happened across some inscriptions while building a tunnel in the area.Some excavation was done near the amphitheater at that time，but no one suspected that an entire city was buried there.The first scientific exploration of the site took place in 1748，directed by Charles of Bourbon.In 1860 Giuseppe Fiorelli invented a system of pouring liquid plaster into the spaces left in the ash bed.Victims had remained in the House of the Fugitives during the volcanic eruption and the fall of ter they had tried to escape under the ashes，but suffocated.The oldest buildings of Pompeii date back to the 6th century B．C.and likely only occupied a small part of the south-western area，between the main Forum and the Triangular Forum.Pompeii gradually expanded toward the east and the north.Most of the ruins date back to its establishment as a Roman colony in 80 B．C.1．What buried the Ancient City of Pompeii in the early afternoon hours of August 24，79 A．D.?_________________________________________________________________ _________________________________________________________________ 2．Who found the Ancient City of Pompeii?_________________________________________________________________ _________________________________________________________________ 【答案】 1.A black river of ash and lapilli from the crater of the volcano.2．The architect Domenico Fontana.Ⅰ.词义搭配1．associate A．an opinion or a judgement about sb./sth. that hasbeen thought about very carefully2．theft B．to make a connection between people or thingsin your mind3．friction C．to choose sb. for a job or position of responsibility4．appoint D．disagreement or a lack of friendship amongpeople who have different opinions about sth.5．steady E．developing，growing，etc. gradually and in aneven and regular way6．assessment F．the crime of stealing sth.from a person or place【答案】 1.B 2.F 3.D 4.C 5.E 6.AⅡ.用下列短语的适当形式填空2．We built a monument on the top of the hill ______ the dead soldiers in the battle.3．He had to ________ his dream because of his bad health.4．I love playing basketball ________．5．We usually ______ lung cancer ______ smoking.【答案】 1.have an influence on 2.in honour of 3.give up 4.in particular 5.associate；withⅠ.阅读P18内容，从三个选项中选择最佳答案－191．Which of the statements is true according to the passage?A.The ancient Greeks had a greater effect on Western civilization than others.B.The marathon was created in honour of Marathon.C.The Greek civilization lasted only 2，500 years.2．How many main temples to Athena on top of the Acropolis?A.Two.B．Four.C．Three.3．What is not the factor that led to the damage to the Acropolis?A.The earthquake.B.The human being.C.The marble.【答案】1－3ACC内容，完成下列表格Ⅱ.阅读P18－196.Destroyed7.stolen8.RestorationcationalⅢ.阅读P18内容，完成下面课文缩写－19The ancient Greeks have had a 1.________ (great) influence on Westerncivilizations than others.

It all starts in the inventor's imagination. Thinking of what would be fun and how it would look means that the inventor has to be creative — like an artist. And, maybe a little like a kid, too! She does some drawings, looks at how other toys work, and decides what parts she needs. Then, she starts building a model called a prototype (原型). The prototype is the starting point for testing and improving the design. Robotic toys are complicated, though.
