Robert?MALE STUDENT: I thought our textbook said that the Egyptians imported their glass from other countries.FEMALE PROFESSOR: Well, until now that's what the evidence seemed to suggest. I mean, we had some evidence that suggested that the Egyptians were making glass objects, uh, but not glass.MALE STUDENT: OK, am-am I missing something? They're making glass, but they're not making glass.FEMALE PROFESSOR: I said they were making glass objects, right? You see, it was previously thought that they weren't actually making the raw glass itself, that they were importing unfinished glass from Mesopotamia—um, which today is a region consisting of Iraq, and parts of Syria, Turkey, and Iran—and simply reworking it. Most archeologists believed that the glass factories were in Mesopotamia because that's where the oldest known glass remains come from. You see, there were two stages of glassmaking: the primary production stage, where they made disks of raw glass… Uh, an- and then there was the secondary stage, where they melted the raw glass, the glass disks, and created decorative objects or whatever.And from this new Egyptian site we've learned that the primary production stage had several steps. First, they took quartz—a colorless, transparent mineral—and crushed it. Then they took that crushed quartz and mixed it with plant ash; uh, “plant ash” is just what it soundslike—the ash that's left after you've burned plant material. They slowly heated this mixture, at a relatively low temperature, in small vessels, um containers, like jars, made out of clay. Uh, and that yielded a kind of glassy material…They took this glassy material and ground it up into a powder, and then they used metallic dye to color it… After that, they poured the colored powder out into disk-shaped molds and heated it up to very high temperatures, so that it melted. After it cooled, they'd break the molds, and inside…there were the glass disks. These disks were shipped off to other sites within Egypt and places around the Mediterranean. Then, in the secondary phase, the disks were reheated and shaped into decorative objects. Susan?FEMALE STUDENT: So what kind of objects were people making back then? FEMALE PROFESSOR: Well, the most common objects we’ve found—mostly in Egypt and Mesopotamia—uh, the most common objects were beads; one thing Egyptians were very, very good at was imitating precious stones; they created some beads that looked so much like emeralds and pearls that it was very difficult to distinguish them from the real thing. Uh, and-and also beautiful vessels, uh, with narrow necks; they were probably really valuable, so they wouldn't have been used to hold cooking oil or common food items; they were most likely used for expensive liquids like perfume. Now the glass made at this factory was mostly red; to get this red color, they used copper; in a sophisticated process. Of course, any kind of glass was very valuable, so these red bottles would only have been owned by wealthy people. In fact, because it was so difficult to make, and sort of mysterious and complicated, it was probably a product produced for the royal family, and they probably used glass to show their power. Also, beautiful, expensive objects make great gifts if you're looking to establish or strengthen political alliances…and it's quite possible that ancient Egyptians were actually exporting glass, not just making it or importing it. The trade with Mesopotamia was probably a friendly, mutual trade…because, uh, Mesopotamian glass was usually white or yellow, so Mesopotamians might have said something like, “We'll give you two white disks for two red disks.” There’s no proof ofthat, uh—at least not yet…题目1.What is the lecture mainly about?A. New information about glass production and use in ancient EgyptB. Whether Egyptians or Mesopotamians were the first to invent glassC. Differences between Egyptian glass and other kinds of glassD. Reasons why ancient Egyptians imported glass from other countries2.What is the importance of the archaeological evidence recently found in Egypt?A. It supports the theory that ancient Egyptians imported glass from Mesopotamia.B. It proves that ancient Egyptians made glass objects prior to the Bronze Age.C.

雅思阅读原文5-4-1READING PASSAGE 1You should spend about 20 minutes on Questions 1-13,which are based on Reading Passage 1 below.Johnson’s DictionaryFor the century before Johnson’s Dictionary was published in 1775,there had been concern about the state of the English language.There was no standard way of speaking or writing and no agreement as to the best way of bringing some order to the chaos of English spelling.Dr Johnson provided the solution.There had,of course,been dictionaries in the past,the first of these being a little book of some 120 pages,compiled by a certain Robert Cawdray,published in 1604 under the title A Table Alphabeticall‘of hard usuall English wordes’.Like the various dictionaries that came after it during the seventeenth century,Cawdray’s tended to concentrate on‘scholarly’words;one function of the dictionary was to enable its student to convey an impression of fine learning.Beyond the practical need to make order out of chaos,the rise of dictionaries is associated with the rise of the English middle class,who were anxious to define and circumscribe the various worlds to conquer —lexical as well as social and commercial.it is highly appropriate that Dr Samuel Johnson,the very model of an eighteenth-century literary man,asfamous in his own time as in ours,should have published his Dictionary at the very beginning of the heyday of the middle class.Johnson was a poet and critic who raised common sense to the heights of genius.His approach to the problems that had worried writers throughout the late seventeenth and early eighteenth centuries was intensely practical.Up until his time,the task of producing a dictionary on such a large scale had seemed impossible without the establishment of an academy to make decisions about right and wrong usage.Johnson decided he did not need an academy to settle arguments about language;he would write a dictionary himself and he would do it single-handed.Johnson signed the contract for the Dictionary with the bookseller Robert Dosley at a breakfast held at the Golden Anchor Inn near Holbom Bar on 18 June 1764.He was to be paid£1.575 in instalments,and from this he took money to rent Gough Square,in which he set up his‘dictionary workshop’.James Boswell,his biographer,described the garret where Johnson worked as‘fitted up like a counting house’with a long desk running down the middle at which the copying clerks would work standing up.Johnson himself was stationed on a rickety chair at an‘old crazy deal table’surrounded by a chaos of borrowed books.He was also helped by six assistants,two of whom died whilst the Dictionary was still in preparation.The work was immense;filling about eighty large notebooks(and without a library to hand),Johnson wrote the definitions of over 40,000 words,and illustrated their many meanings with some 114,000 quotations drawn from English writing on every subject,from the Elizabethans to his own time.He did not expect to achieve complete originality.Working to a deadline,he had to draw on the best of all previous dictionaries,and to make his work one of heroic synthesis.In fact,it was very much more.Unlike his predecessors,Johnson treated English very practically,as a living language,with many different shades of meaning.He adopted his definitions on the principle of English common law—according to precedent.After its publication,his Dictionary was not seriously rivalled for over a century.After many vicissitudes the Dictionary was finally published on 15 April 1775.It was instantly recognised as a landmark throughout Europe.‘This very noble work,’wrote the leading Italian lexicographer,‘will be a perpetual monument of Fame to the Author,an Honour to his own Country in particular,and a general Benefit to the republic of Letters throughout Europe"The fact that Johnson had taken on the Academies of Europe and matched them(everyone knew that forty French academics had taken forty years to produce the first French national dictionary)was cause for much English celebration.Johnson had worked for nine years,‘with little assistance of the learned,and without any patronage of the great;not in the soft obscurities of retirement,or under the shelter of academic bowers,but amidst inconvenience and distraction,in sickness and in sorrow’.For all its faults and eccentricities his two-volume work is a masterpiece and a landmark,in his own words,‘setting the orthography,displaying the analogy,regulating the structures,and ascertaining the significations of English words’.It is the cornerstone of Standard English an achievement which,in James Boswell’s words‘conferred stability on the language of his country.’The Dictionary,together with his other writing,made Johnson famous and so well esteemed that his friends were able to prevail upon King GeorgeⅢto offer him a pension.From then on,he was to become the Johnson of folklore.Questions 1-3Choose THREE letters A-H.Write your answers in boxes 1-3 on your answer sheet.NB Your answers may be given in any order.Which THREE of the following statements are true of Johnson’s Dictionary?A It avoided all scholarly words.B It was the only English dictionary in general use for 200 years.C It was famous because of the large number of people involved.D It focused mainly on language from contemporary texts.E There was a time limit for its completion.F It ignored work done by previous dictionary writers.G It took into account subtleties of meaning.H Its definitions were famous for their originality.Questions 4-7Complete the summary.Choose NO MORE THAN TWO WORDS from the passage for each answer.。

Fill in each blank with the word or phrase that best fits the context.The Clean Meat Revolution Is Coming"If we can grow meat without the animal, why wouldn't we?"This __1__ wasn't from a science fiction writer or the head of The Humane Society of the United States. __2__, this came from Tom Hayes toward the end of his tenure(任期)as the CEO of Tyson Foods. Yes, that Tyson. Synonymous with "chicken," Tyson is by far the largest producer of meat in the U. S.Why would the CEO of Tyson want to __3__ the animal from meat production? In part because meat production will be more __4__ that way -- by growing meat without bones, feathers, or hair, we can get more meat with the same resources. And good things too, as United Nations scientists say that raising and killing animals for food is "one of the major __5__ of the world's most pressing environmental problems, including global warming, land degradation, air and water pollution, and loss of biodiversity." With a growing world population, there are simply not enough resources to __6__ current meat production to feed everyone.Companies around the world are rapidly __7__ the cost of animal-free meat -- meat grown directly in facility __8__ to a brewery(啤酒厂), rather than as part of an animal. This "cell-based meat" is the meat everyone is used to, right down to the DNA. In addition to being more efficient, there will be no waste pollution. And because the meat will be grown in clean conditions, it won't __9__ the use of antibiotics.With all these __10__, the answer to "why wouldn't we?" becomes even more obvious. Although there are technical challenges to increase production to be cost-competitive with __11__ meat, no scientific breakthroughs are necessary to bring meat without the animal to our plates.Perhaps the main question now is which country will lead the way. The governments of Japan, the Netherlands and Israel have already invested in research and startups _12__ producing this kind of meat. Given the magnitude of the global problems that clean meat can help address, those efforts abroad deserve to be __13__.And then just a few weeks ago, the U. S. Food and Drug Administration and the U. S. Department of Agriculture formally announced their plan for joint oversight of clean meat production within their current regulatory framework.This announcement ended months of __14__ and speculation(猜测), giving leading clean meat companies like Memphis Meats and JUST a clear signal that they will have a straightforward and fair path to market in the U.

For each of them there are four choices marked A, B,C and D. Choose the one that fits best according to the information given in the passage you have read.I had a teacher who used to wake up in class by shouting: The early bird gets the worm!”I say let him have the worm”.I hate food that doesn’t stay still, and avoid ‘Japanese restaurant for that very reason. Anyway, I stopped eating worms at the age of three, switching to regular breakfasts of cereal, to which I would add extra sugar.Recently I was thinking about early birds and the competitive spirit after receiving a letter from a reader in Malaysia:“My son deliberately throws away marks because he doesn’t like to be top of the class. What shall I do?”Give him a round of applause for being smart! Actually many children in Asia tend to be the focus by performing better.Placed into a very competitive class when I was 11, I quickly learned the ideal position was second to last. The top three performers and the very last person are highlighted; the second-to-last contestant is INVISIBLE. And it’s an easy position to get- -just deliberately underperform at every test. I could do that I once came second to last in eight straight sports day races. No one suspected anything. I was so invisible that I could have robbed a bank in my street and no one would have noticed.At the London Olympics a few months ago,badminton pairs from three Asian countries deliberately triedto lost matches to draw good lots in later rounds. It was funny to watch, but they were all thrown out for poor sportsmanship. What they really needed were acting lessons their moves were so unconvincing. Oops, I hit the ball in entirely the wrong direction.The other day, I took the children out and they raced for the car. I’m first.”said one. The second said: First is worst,second is best. Together they sang at the last one: And third’s the one with a hairy chest.It struck me that the organizers of sports matches could use this song when people deliberately lost matches. I lost, the delighted loser will say. The judges could still declare them winners, pointing to a new, optional regulation: First is worst, second is best, third’s the one with a hairy chest.1. Why did the author dislike Japanese restaurant?A. Its food was served raw.B. Its food contained worms.C. He was tempted by cereal.D. He was affected by the saying.2. How did the author manage to be invisible in a competitive class?A. He highlighted the top three students.B.He came to second in sports races.C. He hid himself in a bank skillD. he intentionally under performed.3. What can be learned from the passage?A. The judge is encouraged to eliminate the dishonest players.B.Players disqualified from Olympic doubles for using drugs.C. Childrens’song praises the dramatic acting skills of athletes.D.Players purposefully failed for easier lots in the following rounds.4. Which saying might the author possibly support?A. Great minds think alike.B. God favors those who are prepared.C.Honesty is the best policy.D. A bird in hand is worth two in the bush.【答案】ADDC。

91278-英语阅读-8.18-19作业答疑8.18T/F/NG【Passage15 巧克力】5. Chocolate was confined to the rich because people believed it was nutritious.——Falsethe rich和nutritious是关键词,在G段中,第一句提到了chocolate是nutritious, medicinal,第二句说到了a privilege of the rich(= confined to the rich).但是这两句之间没有任何标志表示因果关系,所以题干中的because关系并不成立。
这一类关系混乱的题在判断题中常常会考察,要注意。
另外第二句提到巧克力在mass production大批量生产前是富人的特权,所以也可以发现造成它仅供富人的原因是量少而非nutritious。
10. Handmade chocolates are much more expensive.——Note Givenhandmade chocolates可以直接定位至最后一段中间部分。
Leaf said……harvesting methods. 这句话中说了handmade巧克力是high-quality,意为质量好、高质量,并未直接提及价格问题,也未提及和普通巧克力价格的对比关系,所以是not given。
注意:凡是文中为直接提及的信息都是not given,不要联想。
如本题不能认为平时手工的东西都贵所以手工巧克力也更贵。
不管现实生活是不是这样,文中既然没有提,那就无法判断。

Among the many varieties of clay, the most elaborate in nature is undoubtedly the Bentonite, whose main component, clay called Montmorillonite was discovered in France Montmorillon near Poitiers city in 1847 by two French geologists, DAMOUR and SALVETAT.
The conditions of formation of this mineral are diverse, but most common is the alteration of some eruptive rocks or cinders under the influence of leaching by acidic or alkaline water; there are a few million years.
The first industrial use at the beginning of the last century was made from a deposit located near Fort Benton in Wyoming (USA), hence the name Bentonite which was originally a trade name.
2.Classification
In the 60’s, scientists were able to identify four types of tests to determine a mineral in the family of clays:
Montmorillonite (the main constituent of bentonite) belongs to the Smectites group (swelling clays).

The basic structure of the sheet (platelet), the smaller volume to define the material is composed of two layers of tetrahedral SiO2 (silica) in the middle which is an octahedral layer consists of Al2O3 (alumina). This sheet is about 10 Å is roughly the size of a credit card compared to 1,000 Eiffel Towers stacked.
A defining characteristic of the montmorillonite is the presence of water known as the "bonding water" between each basic sheet. This water contains (mostly) calcium ions called exchangeable cations by alkaline activation. This process is managed at the factory by adding sodium carbonate. The latter takes the place of calcium bentonite in the structure and gives it special properties, such as swelling.
Practically, it is always either primary particles made of a dozen leaves, or micro-aggregates or clusters of leaves, consisting of a few hundred leaves. These are the smallest particles of a well bentonite dispersed in water, and the dimensions of these particles are ultramicroscopic (0.1 to 2 microns).

4.Applications
T hese exceptional properties of the bentonite, allowed its use in many application areas as follows:
• Foundry : link between sand grains that form the mold
• Civil Engineering and oil drilling in the manufacture of mud with a rheology (fluid flow) very particular as to avoid the falling ground, to convey the cuttings in suspension and lubricate tools perforation. • Œnology : for the clarification of wine.
• Detergency as softening agent, active product support....
• Painting to make thixotrope (anti-smear) water-based paints
• Fertilizer / iron ores to bind fine ingredients
• feed additives to agglomerate food & improve intestinal transit • Cosmetics,
• Etc…
To illustrate, here is attached the physical states of bentonite as a function of water / clay ratio :
