Unit 5 Music Grammar and Useful StructuresAimsTo help students learn about the Attributive Clause with a preposition in front.To help students discover and learn to use some useful words and expressions.To help students discover and learn to use some useful structures.ProceduresI. Warming upWarming up by discovering useful words and expressionsTurn to page 35 and do exercises No. 1, 2 and 3 first. Check your answers against your classmates’.II. Learning about grammar1.Reading and thinkingTurn to page 34 and read with me the text of THE BAND THAT WASN’t. As you read on, pay attention to The Attributive Clause (in/ for/ with/ by+which/ whom), that is, the attributive clauses with a preposition ahead of the relative pronoun shown in the sentences.2.Doing exercises No. 1 and 2 on page 35Turn to page 34. Look at the two sentences:The musicians of whom the band was formed played jokes on each other as well as played music. However, after a year or so in which they became more serious about their work, “The Monkees”started to play their own instruments and write their own songs like a real band. Pay attention to the structure: preposition + relative pronoun. Usually only two relative pronouns--- which and whom--- can be used in the Attributive Clause, with a preposition put before the clause. That can’t be used. Look at the screen. Here are more examples on this kind of structure.Now go on to do Exercise No. 2 on page 36, that is, to sort out the sentences.III. Ready used materials for The Attributive Clause (in/ for/ with/ by+which/ whom)In formal styles we often put a preposition before the relative pronouns which and whom:•The rate at which a material heats up depends on its chemical composition.•In the novel by Peters, on which the film is based, the main character is a teenager.•An actor with whom Gelson had previously worked contacted him about the role.•Her many friends, among whom I like to be considered, gave her encouragement.Notice that after a preposition you can’t use who in place of whom, and you can’t use that or zero relative pronoun either:•Is it right that politicians should make important decisions without consulting the public to whom they are accountable? (not --- the public to who they are accountable.)•The valley in which the town lies is heavily polluted. (not --- The valley in that the town...) •Arnold tried to gauge the speed at which they were traveling. (not --- the speed at they were traveling.)In informal English we usually put the preposition at the end in attributive clauses rather than at the beginning:•The office which Graham led the way to was filled with books.•Jim’s footballing ability, which he was noted for, had been encouraged by his parents. •The playground wasn’t used by those children who it was built for.In this case we prefer who rather than whom(although whom is used in formal contexts). In restrictive attributive clauses we can also use that or zero relative pronoun instead of who or which (e.g. ...the children (that) it was built for).If the verb in attributive clauses is a two-or-three-word verb (e.g. come across, fill in, go through, look after, look up to, put up with, take on) we don’t usually put the preposition at the beginning: •Your essay is one of those (which/that) I’ll go through tomorrow. (rather than...through which I’ll go tomorrow.)•She is one of the few people (who/that) I look up to. (not ... to whom I look up.)In formal written English, we often prefer to use of which rather than whose to talk about things: •A huge amount of oil was spilled, the effects of which are still being felt. (or...whose effects are still being felt.)•The end of the war, the anniversary of which is on the 16th of November, will be commemorated in cities throughout the country. (or...whose anniversary is on...)Note that we can’t use of which in place of whose in the patterns described in Unit 71B: •Dorothy was able to switch between German, Polish and Russian, all of which she spoke fluently. (not..,all whose she spoke...)We can sometimes use that...of in place of of which. This is less formal than of which and whose, and is mainly used in spoken English:•The school that she is head of is closing down. (or The school of which she is head...) Whose can come after a preposition in attributive clauses. However, it is more natural to put the preposition at the end in less formal contexts and in spoken English:•We were grateful to Mr. Marks, in whose car we had traveled home. (or...whose car we had traveled home in.)•I now turn to Freud, from whose work the following quotation is taken. (or...whose work the following quotation is taken from.) IV. Closing down by doing exercises:Join the sentence halves using which or whom after an appropriate preposition. (A)a.I would never have finished the work.b.It was primarily written.c.We know nothing.d.They got a good view.e.He learned how to play chess.f.Dennis scored three goals in the final.g.She was born.h.It was discovered.1.They climbed up to the top of a large rock.2. I would like to thank my tutor.3. She has now moved back to the house on Long Island.4. The star is to be named after Patrick Jenks.S. This is the ball.6. He is now able to beat his father.7. The book is enjoyed by adults as well as children.8. There are still many things in our solar system.6. The dragonfly is an insect that we know very little of.Are these correct or appropriate? If they are, put a√. If they are not, give a reason, correctthem and give alternatives if you can. (A)I. It's a piece of jewelry across which I came in an antique shop. --- which I came across inan antique shop. (‘came across’ is a two-word verb.)2. The extra work which she took on was starting to affect her health.3. My mother, after whom I looked for over 20 years, died last year.4. The people whom I work with are all very friendly.5. Some of the criticisms with which they had to put up were very unfair.6. He had many friends with whom he had a regular correspondence.7. The woman to who he is engaged comes from Poland.8. The forms which I had to fill in were very complicated.Rewrite these sentences so that they are more appropriate for formal written English. Use preposition+ which or preposition + whose, as appropriate. (B)I. Tom Sims, whose car the weapons were found in, has been arrested. Torn Sims, in whose car theweapons were found, has been arrested.2. Tom Ham, whose novel the TV series is based on, will appear in the first episode.3. Dr Jackson owns the castle whose grounds the main road passes through.4. Tessa Parsons is now managing director of Simons, the company that she was once a secretary in.5. Allowing the weapons to be sold is an action that the Government should be ashamed of.。

The Story and The Plot :
A story is a narrative following a series of happenings in time order.
A plot, also a narrative, has the emphasis falling on causality(因 果关系).
betwegonist and antagonist; between different points of view; between two moral choices.
A conflict can either be:
external (physical confrontation); or internal (moral, psychological, or spiritual
struggle);
very often, external conflicts are merely projections of internal conflicts.
The Story and The Plot :
A story provides an answer to “What then?” (ordering);
A plot provides an answer to “Why so?” (causality).
The Plot:
Plot is an artificial rather than a natural ordering of events. Its function is to simplify life by imposing order thereon. It would not be possible to recite all incidents, all events, all thoughts passing through the minds of one or more characters during a period. The demands of plot stipulate that the author select from this welter of events and reflection those items that have a certain unity, that point to a certain end. (Hugh Holman & William Hrmon, A Handbook to Literature)

[下图需重画]Ferrous Aircraft MetalsFerrous metals, which applies to the group of metalshave iron as principal constituent, are commonly usedaircraft materials. These materials contain Iron, Steel andits Alloy.Nonferrous Aircraft MetalsThe term “nonferrous” refers to all metals which haveelements other than iron as their base or principalconstituent. This group includes such metals as aluminum,titanium, copper, and magnesium, as well as such alloyedmetals as Monel and babbit.In aircraft construction, Aluminum alloys in which theprincipal alloying ingredients are manganese, chromium,or magnesium and silicon show little attack in corrosiveenvironments. Alloys in which substantial percentages ofcopper are used are more susceptible to corrosive action.The total percentage of alloying elements is seldom morethan 6 or 7 percent in the wrought alloys.Aluminum is one of the most widely used metals inmodern aircraft construction. It is vital to the aviationindustry because of its high strength to weight ratio and itscomparative ease of fabrication. The outstandingcharacteristic of aluminum is its light weight. Aluminummelts at the comparatively low temperature of 1,250 °F. Itis nonmagnetic and is an excellent conductor.The various types of aluminum may be divided intotwo general classes: (1) casting alloys (those suitable for casting in sand, permanent mold, or die castings) and (2) wrought alloys (those which may be shaped by rolling, drawing, or forging). Of these two, the wrought alloys are the most widely used in aircraft construction, being used for stringers, bulkheads, skin, rivets, and extruded sections.Aluminum alloy castings are produced by one of three basic methods: (1) sand mold, (2) permanent mold, or (3) die cast.Magnesium and Magnesium AlloysMagnesium, the world’s lightest structural metal, is a silvery white material weighing only two-thirds as much as aluminum. Among the aircraft parts that have been made from magnesium with a substantial savings in weight are nosewheel doors, flap cover skin, aileron cover skin, oil tanks, floorings, fuselage parts, wingtips, engine nacelles, instrument panels, radio masts, hydraulic fluid tanks, oxygen bottle cases, ducts, and seats. Magnesium alloys possess good casting characteristics.Magnesium alloys are subject to such treatments as annealing, quenching, solution heat treatment, aging, and stabilizing. Sheet and plate magnesium are annealed at the rolling mill.Titanium and Titanium AlloysIn aircraft construction and repair, titanium is used for fuselage skins, engine shrouds, firewalls, longerons, frames, fittings, air ducts, and fasteners.Copper and Copper AlloysIn aircraft, copper is used primarily in theelectrical system for bus bars, bonding, and aslockwire.Beryllium copper is a recently developedalloy containing about 97 percent copper, 2percent beryllium, and sufficient nickel toincrease the percentage of elongation.Brass is acopper alloy containing zinc and small amountsof aluminum, iron, lead, manganese, magnesium,nickel, phosphorous, and tin. Brass with a zinccontent of 30 to 35 percent is very ductile, butthat containing 45 percent has relatively highstrength.Metalworking ProcessesThere are three methods of metalworking: (1)hot working, (2) cold working, and (3) extruding.Depend on usage, both hot and cold workingmethods may be used to make a single part.Task 1: Answer the following questions:1 what are the important properties ofthe metals and their alloys?_______________________________________________________________________________________________________________________2 what are the main kinds of aluminumalloys used in the aircraft industry?_______________________________________________________________________________________________________________________3 what is nonferrous metal?_______________________________________________________________________________________________________________________ _______________________________________________________________________________________________________________________4 what is the most significant quality of magnesium metal?_______________________________________________________________________________________________________________________ _______________________________________________________________________________________________________________________5 please give three usage of titanium alloy in aircraft industry._______________________________________________________________________________________________________________________ _______________________________________________________________________________________________________________________ Task 2: choose one aircraft material from the passage, and talk about its qualityTask 3: Read the following passage about Composites and present the history of aircraft materials based on the graph.Nonmetallic Aircraft MaterialsThe use of magnesium, plastic, fabric, andwood in aircraft construction has nearlydisappeared since the mid-1950s. Aluminum hasalso greatly diminished in use, from 80 percent ofairframes in 1950 to about 15 percent aluminumand aluminum alloys today for airframeconstruction. Replacing those materials are 5-32nonmetallic aircraft materials, such as reinforcedplastics and advanced composites.Composite MaterialsIn the 1940s, the aircraft industry began todevelop synthetic fibers to enhance aircraftdesign. When composites are mentioned, mostpeople think of only fiberglass, or maybe graphiteor aramids (Kevlar). Composites began in aviation,but now are being embraced by many other industries.A “composite” material is defined as a mixture of different materials or things. This definition is so general that it could refer to metal alloys made from several 5-33 different metals to enhance the strength, ductility, conductivity or whatever characteristics are desired. Likewise, the composition of composite materials is a combination of reinforcement, such as a fiber, whisker, or particle, surrounded and held in place by a resin, forming a structure. One composite, concrete, is composed of cement (resin) and gravel or reinforcement rods for the reinforcement to create the concrete.Task 4: Read the following illustration about structure material usage on C-17A and present it with your partner.C-17A Structural Material UsageTask 5: Read the following passage and design a sheet about aluminum alloy’s quality.Effect of Alloying Element1000 series. 99 percent aluminum or higher, excellent corrosion resistance, high thermal and electrical conductivity, low mechanical properties, excellent workability. Iron and silicon are major impurities.2000 series. Copper is the principal alloying element. Solution heat treatment, optimum properties equal to mild steel, poor corrosion resistance unclad. It is usually clad with 6000 or high purity alloy. Its best known alloy is 2024.3000 series. Manganese is the principal alloying element of this group which is generally non-heat treatable. The percentage of manganese which will be alloy effective is 1.5 percent. The most popular is 3003, which is of moderate strength and has good working characteristics.4000 series. Silicon is the principal alloying element of this group, and lowers melting temperature. Its primary use is in welding and brazing. When used in welding heat-treatable alloys, this group will respond to a limited amount of heat treatment.5000 series. Magnesium is the principal alloying element. It has good welding and corrosion resistant characteristics. High temperatures (over 150 °F) or excessive cold working will increase susceptibility to corrosion.6000 series.
