Transport Guide
The Brisbane City Council(BCC)is responsible for bus and ferry services with in the city limits and suburbs．Most buses will either arrive at the city or an interchange where connecting buses can be caught．BCC buses operate from 5：30 am to 11：00 pm Monday to Thursday and 5：30 am t0 12：00 am on Fridays .On weekends and public holidays buses operate less frequently Pre—paid bus tickets can be purchased from the QUT (Queensland University of Technology)bookshop，the campus newsagency．most other newsagencies and general stores，and any BCC Customer Service Centre．Short-term students at QUT cannot use their ID cards to gain a discount fare on BCC public transport．You will need to buy an adult ticket to travel．Bus fares are dependent on the number of zones you have to travel．There are several types of tickets：
Single：one way ticket to reach your destination，including transfers within 2 hours．
Daily: unlimited travel within the zones．
Off-peak’ Daily：discounted unlimited travel between 9：00 am and 3：30 pm and after 7：00 pm
Monday to Friday, and all day on weekends and public holidays．
Weekly：unlimited travel within the zones for one week from the date of issue．
Monthly：unlimited travel within the zones for one calendar month from the date of issue．
Ten-trip Saver: 10 trips at any time within the zones on buses and ferries only．

Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．
Components of Soft
Soil is made up of a number of layers(層)，each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus(腐殖質(zhì))，which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．
Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2．000 years ag0．
Water Beneath the Soil
Surface water collects and flows above the ground in lakes．ponds．a(chǎn)nd rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation(滲透)．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．
As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.
Soil pH
Soil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rock
from which it was formed．a(chǎn)nd by the nature of t}le plants that grow and rot in it．
The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．
67．The layer of soil that provides necessary nutrients for plant growth is called．
A．1itter B．topsoil C．humus D．subsoil
68．According to the text．which of the following is NOT true?
A．Soil forms from weathered rock on the earth surface．
B．The deeper layer of soil is darker in colour than t}le surface soil．
C．Air pollution is partially responsible for acid soil．
D．Groundwater tends to carry away nutrients for plant growth．
69．We can infer from the passage that the water table lies ．
A．between the topsoil layer and the subsoil layer
B．in the subsoil layer above bedrock
C．between the subsoil layer and bedrock
D．in the bedrock layer beneath the subsoil
70．The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ．
A．rushed away into the river
B．cleaned and purified by water
C．destroyed and carried away by water
D．mixed with water and become part of it
