(iii) How items not dealt with by an IFRS for SMEs should be treated. (5 marks)

正确答案：
(iii) The treatment of items not dealt with by an IFRS for SMEs
IFRSs for SMEs would not necessarily deal with all the recognition and measurement issues facing an entity but the key
issues should revolve around the nature of the recognition, measurement and disclosure of the transactions of SMEs. In
the case where the item is not dealt with by the standards there are three alternatives:
(a) the entity can look to the full IFRS to resolve the issue
(b) management’s judgement can be used with reference to the Framework and consistency with other IFRSs for SMEs
(c) existing practice could be used.
The first approach is more likely to result in greater consistency and comparability. However, this approach may also
increase the burden on SMEs as it can be argued that they are subject to two sets of standards.
An SME may wish to make a disclosure required by a full IFRS which is not required by the SME standard, or a
measurement principle is simplified or exempted in the SME standard, or the IFRS may give a choice between two
measurement options and the SME standard does not allow choice. Thus the issue arises as to whether SMEs should
be able to choose to comply with a full IFRS for some items and SME standards for other items, allowing an SME to
revert to IFRS on a principle by principle basis. The problem which will arise will be a lack of consistency and
comparability of SME financial statements.

Directions: In this section, you are asked to write a composition with the title “The Biggest Dream of My Life.” You should write at least 120 words and cover the following points.

1. What is your biggest dream? 2. Why do you have it? For how long have you got it? 3. What are your plans to achieve your dream?

参考答案：

The Biggest Dream of My Life I know many people whose biggest dreams are things such as what career they want to get into, how much money they can earn. My dream is nothing like that. My biggest dream has always been and will always be to travel around the world. I have one life here on Earth, so I don’t want to die regretting that I didn’t see it all. Actually I have had this dream ever since I was in primary school. In one geography class, when the teacher presented us the globe and national ﬂ ags of various nations, I thought I found the dream in the depth of my heart. And the moment I came to college, I had always envisioned myself of becoming a nomad. I would roam around the world. No permanent address. Any place can be my home and I am home within myself. Meanwhile, I am aware that it’s really a costly dream. The first step I need to take is to begin to save money to support it. And I think it’s a good idea to start exploration from my hometown and the city where my university is located. Just as a saying goes: a big dream begins with the first step.

Directions: For this part, you are allowed 30 minutes to write a short essay entitled How Should Parents Help Children to Be Independent? You should write at least 120 words following the outline given below.

1. 目前不少父母为孩子包办一切

2. 为了让孩子独立, 父母应该……3. 总结

正确答案：Recently, numerous reports related to children's dependence on their parents on various media have, once again, aroused wide concern among public about kids' lack the ability to face their lives by themselves. It is widely accepted that excessive reliance on one's parents is bound to be harmful to his prospect and thus it is necessary that some urgent actions be taken to alter current trend.
For one thing, more opportunities should be given to children to participate in different competitive and cooperative activities, for competition is one of effective ways to lead them to achieving outstanding accomplishments and cooperation can build trust between each other and help to bring long-term relationship among peers. For another, it is suggestive that children receive some outward-bounds, which are beneficial to kids' physical and emotional endurance, to inspire children's underlying potentials and shape their best character and consequently cultivate their awareness of independence.
In a nutshell, parents are supposed to be subject to the limitations of traditional concepts of raising a child; on the contrary, children ought to be offered more chances to explore as many as possible areas in their lives to find their optimal careers. Accordingly, the cultivation of the ability to be independent might be regarded as a basic education, which plays a crucial role in a child's all-round development.
