The top storey looks like an observation lounge.CThe student hostel is constructed of white concrete andglass. Some solid vertical concrete columns are placeda t intervals along the front elevation. All the windows aree ither square or rectangular.EThe assembly room is a three-storey six sided building.The windows on the ground and first floor are rectangular,surrounded by elevations of natural stone. The third storeyis a roof terrace. A six-sided stone framework surroundsa six-sided conical pyramid constructed of glass withaluminum strips.
The assembly room is linked to the mainbuilding by enclosed walkways on two levels.2314 Word list1 1 pointed23452circularellipticalcurved9 tapered10 diagonal678doughnut-shapedinclinedzigzagperpendicular1 optional 2 extensivestable 5 pointed346781Nouns (buildings)Adjectives (shapes)circularcurved [one syllable]curvilineardiggonalQiagriddoughnut-shapedinclinedQvalperpendicular"pointedsemi-circular@Dered10 Disasters2113Speculation1 compression 2 impact 3 wear4 fracture 5 buckling 6 thermal shock7 investigation 8 metal fatigue 9 corrosion10 collapse 11 tensionVertical word: speculation1234567821wouldn't haveshould ha\-e beenIntroduction: f, iBackground: c, IMethod: b, jFindings: a, eConclusions: d, hRecommendations:g kNOUNSADJECTIVESVERBS><The rail crash must have been caused by a broken rail.The rail may have suffered thermal shock due toexcessive heat.The aircraft might not have had a mechanical failure.The flight crew could have fallen asleep due to cabindepressurisation and lack of oxygen.The captain might have wanted to save time bysteering close to the headland.He may not have realised that the depth of water inthe channel was insufficient.The houses can't have collapsed in the earthquakebecause of a design error.The disintegration of the bridge might not have beencaused by substandard concrete.Investigation1 No 2 No 3 No 4 21 months before crash5 other company 6 backlog of essential maintenancework 7 6 months 8 rail replacement 9 USA,Sweden 10 3 11 £6 millioncatastrophiccompressioncompresscompressiveexcessexceedexcessivedestructiondestroydestructivebucklingbucklecollapsecollapse~corrosioncorrodedisintegrationdisintegratefracturefracturerustrust::><:~ llilltical~zag24should have soundedmust have failedmust have beenshould placeshould be checkedshould be installedshould inspectshould be increasedcatastrophecompactaluminiumarchitectbeautyconcreteelevationfunctionillityinnovationstorey34 Word list43152should have beenhadn'tReports23HThe research centre has a rectangular floor plan.
