b) They are adaptable to uneven（不平坦的） floor level *
c) They are available in many different sizes
d) None of the above
3. Which of the following is essential（要素） to achieve efficient and effective construction ?(20~22)
a) Quality of the final product of the concrete structure
b) Safety of all site personnel（全体人员）
c) Productivity which relates to cost and time effectiveness
d) All of the above *
4. Which of the following is NOT an advantage of using timber formwork ?(25)
a) Its initial cost is cheaper compared to other formwork
b) It's easy to handle and transport
c) Its surface is hard enough to resist damage even after many uses *
d) It's able to take considerable load
5. Which of the following should be emphasized（强调） when considering the practical aspects of timber formwork ?(25)
a) It's easy to handle and transport
b) It's able to take considerable load
c) Its initial cost is cheaper compared to other formwork
d) All of the above *
6. Which of the following is NOT a disadvantage of using timber formwork ?(25)
a) Require skilled labour to assemble
b) Timber absorbs water which reduces the strength of concrete
c) Unless well-finished ,it gives a rough texture to the concrete surface
d) None of the above *
7. Which is the correct sequence（顺序） to assemble（安装装配） formwork ?(35)
A) Beam side forms
B) Beam soffit and staircase forms
C) Internal forms of peripheral columns and walls
D) Slab soffit forms
E) External forms of peripheral（次要的） columns ,walls and refuse chutes（垃圾槽）
F) External side forms of peripheral beams
a) F-B-C-D-E-A
b) E-C-B-A-D-F *
c) C-A-D-F-E-B
d) E-D-A-B-C-F
8. After the initial setting-out of columns and walls ,kickers are cast and horizontal lines are marked on the kickers ______ above the floor slab (35)
a) 75mm
b) 100mm *
c) 125mm
d) 150mm
9. Why is it that concrete pressure acting on the face of the stop end may exceed that on the form face ?(37)
a) The reflection and rebound of energy from vibration during concreting causes the increase in pressure *
b) This is the location where the concrete will most likely be dropped ,hence the impact pressure is higher
c) Concrete always flows towards the stop-end ,causing an increase in pressure there
d) None of the above
10. Which of the following is NOT a parameter(参数) that governs(管理) the structural behavior of formwork and falsework ?(39)

d) All of the above *
12. Which of the following is NOT a factor contributing to the instability(不稳定的) of formwork and falsework ?(51)
a) Overloading
b) Grade of concrete *
c) Forces created by machineries
d) Support settlement(支点沉降) at the soleplates
13. Side thrust(推力) from liquid concrete is caused by ______ (52)
