D。need 作为情态动词的疑问词，其肯定回答一般用 must。其否定回答为“needn\'t”。5 . A。回答 must 引出的问句时，如果是否定的回答，不能用 mustn\'t ( mustn\'t 表示绝对不可 ) ，而要用 needn\'t 或 don\'t have to。6 . C。“must be + 表语”结构表示体力或脑力方面的能力。A 项时态不对，C 项本身错，D 项中 can 与 be able to 不连用。8 . C。can 表示“能力”而 be able to 表示经过一番努力才达到目的。从 He worked very hard 判断，应选 C。9 . B。must 表示谈话双方主观上认为“有义务”、“有必要”去做某事，而 have to 表示客观需要。另外 must 一般不用于过去式句中，但可用在间接引语中。10 . C。对过去发生的事情的推测，要用“can／could + have + 过去分词”。11 . B。对过去发生的事情的疑问推测也用“can／could + have + 过去分词”。12 .

答案与简析：
1 . belong 表示“属于”，是不及物动词，常与介词 to 连用，不能用被动语态，应把 was 去掉。 2 . 表示一个动作正在进行时，突然又发生了下料想不到的动作，须用并列连词 when，意为“那时”、“这时” = and then , 应把 while 改成 when。 3 . used to do sth . 表示“过去常常……”，和现在对比，现在不这样了；be used to sth . ( doing sth . ) 表示“习惯于……”，可用于各种时态。该句主句谓语动词的用法属于前者，应把 used 前的 was 去掉。 4 . 该句 It 为形式主语，真正的主语是置于句子后部的 to get to the top of a company。该句是指做某事困难，而没有比较的意味，因此作表语的形容词应用原级，应把 harder 改成 hard。 5 . “so…that…”意为“如此……以至于……”，是一个固定句型，so 修饰形容词或副词，表示程度，that 引导一个结果状语从句，应把 very 改成 so。 6 . 句中作表语的 hurt 是由过去分词演变过来的形容词，须用副词修饰，应把 bad 改成 badly。 7 . with a smile = smiling 表示“微笑着”，是固定的介词短语，应在 smile 前加 a。 8 . 按照英语习惯用法，same 作形容词修饰名词时，其前通常加定冠词 the，应把 a改成 the。 9 . fun 表示“乐趣”，“兴致”是不可数名词，应把 fun 前的 a 去掉。 10 . 表示事物的性质或特征，通常用形容词作表语，应把 easily 改成 easy。 11 . 按照英语时态的呼应规律，在条件状语从句中须用一般现在时代替一般将来时，应把 will stop 改成 stops。 12 . 先行词为表示地点的名词 lab , 关系词在定语从句中作及物动词 visited 的宾语，只能用关系代词而不能用关系副词，应把 where 改成 which 或 that。
