2005 #11 神奇題目
溫室氣體係泛指所有會trap heat係atmosphere 令到solar radiation比正常re-radiate得少d出地球既氣體。
因為水都會trap heat既緣故
水氣都係greenhouse gas =)你惟有咁記啦

順帶一提,sulphur dioxide唔係greenhouse gas

2007 #32 詳解
以下既原因可以解釋點解人造雨唔係解決少年降雨 (producing artificial rain cannot solve the problem of low annual rainfall)因為:

- 從logic看,人造雨只可以解決一個細範圍地域冇咩雨落既情況,而low annual rainfall係一個自然現象,人可唔可以透過人造雨令個天落多d雨(自然的precipitation)?
- 從geog sense黎講, 現今人造雨既成效都唔係太高,以中國為例,內地曾經有試過以人造雨解決 乾旱問題,但成效唔太大。
- 至於joint-us的答案,依我所見係正常既諗法,所以大家真係當佢係一個o岩既option亦無可厚非,當然筆者做卷個陣亦都mistakenly 當依個係一個合理原因。
- 至於出題者set 題既logic,由於我地無從稽考,我惟有講一句: 祝大家好運!


1. Urban encroachment等於urban sprawl?
Urban Encroachment: With higher demands of land, the population and economic activities have spread to the suburbs and rural area. Rural land is turned into urban land uses, known as urban encroachment.

Urban Sprawl: Urban sprawl refers to the unplanned expansion of urban land use into surrounding rural area.

兩者focus並不同,後者帶-ve meaning. 對City concept唔熟悉,請看# 47

2. 如果你對Plate tectonics所產生既landforms/annotated diagram應該點畫?
有疑惑,可參考 #202的post.

3. 有關Biotech 的post #120
註: 使用biotech不會令biodiversity下跌。

Biotech 的drawbacks:
i) since a lot of these technologies are patented (專利化),
ii) using them in farming is very costly
iii) unknown effect to the ecosystem, potential threat to the habitat
iv) unknown effect to human beings

4. 點樣答same physical constraints 但情況不一?
- different cultural inputs 如 technology, capital, government support

所以Sahel 使用extensive farming (transhumance + nomadic herding 適應氣候問題)
詳參 2007 PP1 Q.6

5. Reclamation 的壞處:

- swifter water current/ flow of river will be affected
- increase in turbidity of sea water
- destruction of marine habitats
- construction work causes water pollution (e.g.倒泥)
- huge cost incurred if the river bed is deep
- the habour/river will become narrower
- a large area of reclamation disturbs the natural environment
- high-rise building built on the reclaimed land will cause "wall" effect and black ventilation in the district and
- spoil the scenery of the harbour
- this increases the potential flow of people and vehicles, causing more serious pollution threat

Specifically: (如以東涌灣填海為例)
- mangroves and wildlife habitat will be disrupted
- sewage from the original settlements along the floodplain in Tung Chung may not be brought away rapidly

6. How does global warming decrease food production? Discuss.

一般同學係理解global warming既effect,只會想到temperate areas 既cropping period延長,因此適合更長的耕作,甚至做到triple-cropping.
這個想法並無不妥。 但問題是GW同樣可以lower food supply/production,因為

- coastal farming activities are disrupted as a result of rising sea level
- increasing pests and diseases, e.g. locust (蝗蟲)
- loss of fertile arable land due to flooding
- intensify salinisation

7. 點解deforestation 會加深Global warming的影響?
- during the process of deforestation, it may involve the burning of trees, which produce large amount of CO2 in the atmosphere
- besides, deforestation reduces the amount of CO2 to be absorbed by plants during photosynthesis,
- effectiveness of the natural carbon cycle is disrupted.

8. 究竟Sahel 地區的famine是human factor還是自然因素影響較大?

對於這類open-ended的問題,我想大家可以這樣答 (如果你諗到更加多既human factors contributing to the famine problem),咁你可以話係前者影響較大。

Natural factor:
- unreliable rainfall and low annual rainfall (200-450 mm)
- low soil fertility which discourage intensive farming activities
- failure in crop and livestock production

Human factor:
- rapid population growth due to advancement in medicine
- political instability
- demand for food>existing food supply
- low level of farming technology (use of primary and traditional farming methods)
- low food productivity
- lack of capital and government support to import food
- nearly no long-term irrigation projects/agricultural programmes are carried out as a result of frequent changes of government
- over-extraction of under ground water
- environmental degradation

9. 怎樣解決drying up of Huang he?
a) increase water supply
- drilling more wells
- increasing water storage facilities by building more dams to store water (e.g. Xiaolangdi)

b) reduce water consumption
- control water usage by legislation
- develop water conservation technology for water-demanding activities
- e.g. drip irrigation projects and use of drought-resistant varieties
- readjust the industrial structure

c) reduce water wastage
- by education
- arousing public concern over the importance of water conservation
- increase the waster charges

d) improve water resources management
- regulate the water stored and the drainage of the reservoirs in times of drought
- maintenance of the reservoirs and the river channels in the Huang he basin

10. Industrial relocation 的drawbacks?
- cultural conflicts aroused with the minorities
- lack of skilled labour as a result of sparsely populated pattern
- high transport cost when delivering the products to the markets
- industrial inertia
- loss of agglomeration economies
- high relocating cost and venture capital

Economic aspect:
- balanced economic development
- attain regional self-sufficiency
- alleviate the problem of mismatch of locations between energy consumption and production
- ensure a steady supply of energy

Social aspect
- create more job opportunities
- raise the standard of living
- provide skilled labour for industries in the West while redistributing the factories
- relieve the problems of overpopulation and unemployment in the cities

Political aspect
- integration of minority races

Strategic aspect
- industries in the interior regions are less vulnerable to foreign attacks

11. 在中國用煤是否真的一點好處也沒有?
- easy to extract
- cheap in extraction
- large reserve in China (coal fields)
- incur no conversion cost as they are directly used after extraction

12. Chnages in the locational factors of IS industry in China  (2008 大熱)轉載至 1988年會考
- pull of coal fields reduces/more scrap irons available in the market
- market becomes a dominant factor
- importance of iron supply increases, while labour supply remains constant

- reduction in coal used per tonne of iron produced
- due to technological improvement in steel making
- use of scrap iron reduces coal needs

- greater demand from market
- due to development of other steel-based industries
- increases in population (market)

- development in bulk transport/large carrier
- lower cost of shipping of iron ore
- as coal needs decreases, factory nearer to iron ore fields

- port site easy access to markets
- and easy access to raw materials sources
- improvenemt in transport means/ port facilities lowers cost of shipping

- other factors such as government interference
- industrial integration demands more land

可唔可以講下geog substainable city通常問乜同埋要答d乜??
我mock 基本上一分都拎唔到..thx!!


Sustainable City:
- What is urban decay?
- What is urban encroachment?
- What is urban sprawl?
- What is suburbanisation & rural-urban migration?

i) 分辨圖中 城市問題 (如你見到一個舊區(inner city),你就會諗起urban decay)
ii) 題目可能會想同學分析urban renewal 中有咩方法可以解決圖中既環境/衛生/樓宇結構等等既問題
iii) 題目亦會要求考生例舉收地面對既問題 (如land assembly 中multi-ownership)
iv) 最難既就可能會問你一d 解決land assembly既方法 或者還原基本步 =>
v) 要求考生分析要締造一個sustainable city,題目中提及既urban renewal project點樣達到平衡
economic interest/social harmony/environmental protection依幾個大方針

要緊要,係你要了解urban renewal既 objective,一定係以人為本。

- Geography
- Economics
- History

依3科(CE Level)既問題。


各位努力 ...

1. 兩塊大陸板塊相撞,有沒有涉及convection currents?
2. 地圖題既locational factors好難諗, 要以乜野思考方式推出黎?

1. EEC好似未問過, EU就問過, 會點問? specific D咁問, 定係兩個bloc比較問?
2. Balkan好少野, 會點出?
3. 蘇聯解體係咪唔駛仔細溫?
4. 蘇聯革命立國駛唔駛溫?
5. HK政治考唔考?


1. 兩塊大陸板塊相撞,有沒有涉及convection currents?

就係因為下底有movement of magma,而magma current係diverge/converge就衍生唔同既plate boundaries.
所以當2塊plate相撞係一定涉及convergence of magma currents

2. 地圖題既locational factors好難諗, 要以乜野思考方式推出黎?
- 話明地圖就梗係參考地圖有既野
問親locational advantages,你要睇下問題屬於邊一類
有d係關於urban knowledge,例如比一幅城市既地圖,你好易就聯想到係個度住
從land use 黎睇,個度既 accessibility (可達程度)會比係郊區為高
另外,map都俾佐一d conventional sign你,睇下有冇d institutional building structures/或者題目暗示既野

簡單黎講,諗親locational advantage 都要base on map evidence,指出佢幾個格仔有d乜而其他地方欠奉既,咁好大程度上都十拿九穩!

1. EEC好似未問過, EU就問過, 會點問? specific D咁問, 定係兩個bloc比較問?
- 我諗你可以從英國做一個case study去諗
- 諗下兩者有咩共同點/轉變, 前者點解會變成EU?

2. Balkan好少野, 會點出?
- 佢唔係USSR既衛星國
- 會有Pan-Slavism既出現
- 會引起 struggle for independence,如 Slovenia/Croatia 獨立,相比起其他成員冇引黎太大流血衝突

3. 蘇聯解體係咪唔駛仔細溫?
4. 蘇聯革命立國駛唔駛溫?
- 立國唔細點溫,因為唔係重點
- 解體原因可以花多些少時間

5. HK政治考唔考?
- 考就應該會考,不過dbq 熱門度比其他課題為低
- essay可能會問 HK政治/經濟/文化發展點受大陸影響。



好post, 支持樓主 =]


1. 點樣可以由個表到移位睇到+左tax/subsidy 之後個新既market price?
應該係QD 移上移落定係QS?

2. share 同 debenture 有咩明顯既分別



demand &supply diagram
幾時要同時有demand suppy curve?,,幾時又只shows其中1條?
仲有supply curve幾時用直線?


1. 點樣可以由個表到移位睇到+左tax/subsidy 之後個新既market price?
應該係QD 移上移落定係QS?

如果係tax, EP會升, 而個QD會跌
咁你應該跟個tax range搵返跌佐既QD係邊個新price level對應其QS
你試下睇返 http://lsforum.net/board/viewthread.php?tid=53926

2. share 同 debenture 有咩明顯既分別
- 最明顯就係
- Share holders are owners of the firm while debenture holders are creditors of the firm. Therefore, share holders may have say in the management of the firm but not for the creditors.
- 另外share holders係receive dividend, debenture holders係收 interest


demand &supply diagram
幾時要同時有demand suppy curve?,,幾時又只shows其中1條?
仲有supply curve幾時用直線?

前者: 要睇題目俾佐d咩information你,冇提過change in demand or supply or equilibrium price
後者: 一般marking scheme (考評局)有時會畫佐一條vertical supply curve
其實,只要打斜畫個陣都唔影響answer 要搵既野,無論係跟佢用打棟或打斜畫仁都唔會出事。

惟一既例外,就係題目指明supply係fixed或者有相關提示,考生就一定要用一條fixed supply curve去解釋。

subsidy ...
如果subsidy 應該係個QD會升? 個EP 會下降?


let subsidy = $2
你睇下EP跌到去邊個price level個Qd = Qs (例如6蚊 QD=40,,對應既price係8蚊,睇下8蚊個Qs係咪40)
