18．Taking Questions
When giving presentations，it is common practice to encourage audience involvement and this often takes the form of questions from the audience．A good deal has been written recently discussing the advantages and disadvanges of various approaches to handling these．（71）E
One approach is to take questions as and when they arise．Usually there are only a few points from the audience but in the event of receiving too many，the presenter may move the presentation on by reminding the audience of the time，and offering to continue the discussion later．（72）BThose who aren't will simply have to wait．
（73）C A danger here is that too much time may be wasted on questions and，as a consequence，important parts of other main points have to be edited out．The audience may also confuse the presenter by asking about points that he or she intends to cover later in the presentation．If this happens，it is important to make the audience aware that answering their questions now might weaken the structure of the talk．
Alternatively，mid-point questions can be discouraged by signalling that you would prefer questions at the end．If you take this approach，however，it is important to bear in mind that when you get to the end，it may take a little time for people to reflect on what they have heard and to formulate a question．（74）F To overcome this，it is useful to have a chairperson who is prepared to ask the first question．
（75）A In that case，the safest response is to tell the truth．Then the rest of the audience may appreciate your honesty．It may also be possible to move the attention away from the questioner by asking other audience if anyone else can provide an answer．
A．Another potential problem is unfriendly questioners who ask the kind of questions they know will be difficult to answer．
B．A statement such as"I will come back to this point at the end"should keep most people happy．
C．Another approach is to ask for questions after each main point has been addressed．
D．It is a good idea to be aware of the traps that this type of questioners try to set．
E．However，my intention here is simply to present the most common approaches．
F．There is even the possibility that an embarrassing silence may ensure．
G．Seeking a question can be an effective way of moving the session on．
分析 在给出陈述的时候，通常的做法是鼓励观众参与，即鼓励观众以问题的形式．但这种做法有缺点也有优点．文章作者介绍了最通常的做法．
解答 71．E 72．B 73．C 74．F 75．A
71．E 细节题．根据前句A good deal has been written recently discussing the advantages and disadvanges of various approaches to handling these可知，近期写了很多关于讨论处理这种问题的方法的优缺点，所以下句对应也提到了approaches，故选E．
72．B 上下文语境．根据该段的第一句话One approach is to take questions as and when they arise可知，其中之一的方法是当问题出现 就认真对待并处理，所以选项B即使回到该问题的陈述最受大家欢迎，故选B．
73．C 概括题．通过上一段的 One approach is to take…是介绍一种方法，自然下段会提到另外一种方法，即C．
74．F 上下文语境．前句it is important to bear in mind that when you get to the end，it may take a little time for people to reflect on what they have heard and to formulate a question告诉我们要有心理准备，即到最后人们需要有时间去反思所听到的，所以会有沉默期，故选F．
75．A 概括总结．通过最后一段的这句话In that case，the safest response is to tell the truth得知，如果出现这种情况，最保险的方法就是说真相，可见前面应该是提到一种不好应付的情况，而选项A正好是遇到的一个棘手的问题，即提问者提出了一个不好回答的问题，故选A．
