(1)句中must have happened属于“情态动词＋have done”的结构。 (2)情态动词的基本用法：
a．ought to表示责任和义务，意为“应该”，与should同义。还表示可能性，一般指较大的可能性，意为“按道理应该”。
b．have to意为“不得不”，有时态、人称和数的变化，其否定形式和疑问形式需要借助于助动词do。在否定结构中，don't have to表示“不必”；mustn't表示“禁止，不许”。
c．need作情态动词时，后跟动词原形，表示“需要，有必要”，无人称和数的变化，多用于否定句、疑问句或条件句中。作为实义动词，表示“需要”，后跟名词、代词、不定式、动词的-ing形式等。构成否定句和疑问句时要借助于助动词do。
(3)“情态动词＋have done”结构的用法
a．must have done表示对过去发生事情所做出的合理或确有把握的推测，意为“想必/准是/一定已做”，只用于肯定句中，在否定句或疑问句中通常被can not/can't＋have done代替。
b．can have done一般用于疑问句或否定句中，用于表示对过去所发生事情的推测。could have done用于肯定句时，表示“本有能力做某事而未做”。
c．should/ought to have done表示“过去本应该做某事而(实际上)没有做”，含有责备或遗憾的语气；其否定形式表示某种行为不该发生却发生了。
d．may/might have done表示对过去发生的事情的推测，意思是“也许已经做了某事，可能已经做了某事”，多用在肯定句中，用might时表示语气更加不肯定。
e．need not do sth. 表示“不必做某事”，needn't have done sth. 表示“本不必做某事却做了”。

篇章导读：本文是一篇记叙文。没有人比“我”的父母，尤其是“我”的父亲，更爱“我”了。他会为“我”虚度光阴而伤心，也会为“我”做了有意义的事而高兴。为了他，“我”总是提醒自己不要半途而废。
1．with 考查介词。此处用“介词with＋宾语(名语短语)＋宾补(介词短语)”构成with的复合结构。
2．to approach 考查非谓语动词。分析句子结构可知，此处应用不定式和hard一起作宾语补足语。
3．talented 考查词性转换。修饰名词man应用talent的形容词形式talented，作定语。talented “有才能的，有才干的”。
4．has provided 考查动词的时态。分析语境可知，此处应用现在完成时表示父亲多年的努力和辛苦对现在产生的积极影响。
5．relatively 考查词性转换。修饰形容词rich应用副词。
6．whom 考查非限制性定语从句的引导词。先行词是people，指人，关系词在介词后面，作宾语，故填whom。此处表示“我”从来自各行各业的人那里获得丰富的社会经验。
7．expectations 考查名词的数。expectation作“期望”讲时，通常用复数形式；have high expectations of sb.“对某人寄予厚望”。
8．hurts 考查动词的时态和主谓一致。此处表示“我”虚度光阴深深地伤害了他。结合上下文时态判断，此处应用一般现在时，动名词的复合结构“my idling time away”作
14
主语，谓语动词用单数，故此空应填hurts。
9．writing 考查非谓语动词。此处在“such as”后面作宾语，故应用动名词。 10．will 考查助动词。此句是否定副词never位于句首的倒装句，故此空应填入助动词或情态动词，结合语境可知，此处表示“我”的决心和承诺，故用助动词will。

难项分析：
第一处：去掉about或if→whether 考查宾语从句的连接词。由介词about可知，应用whether引导宾语从句，介词后的宾语从句一般不用if引导。也可删去about，由if引导该宾语从句。
第五处：Beside→Besides 考查副词。besides在此处的意思是“此外”，beside是介词，意为“在……旁边”，根据语境可知，应把Beside改为Besides。
