Answer 1

46．a 考查冠词．responsibility作"道德义务"讲时，常用单数形式，其前加不定冠词a．    
47．are 考查主谓一致．这是一个倒装句，主语some of the major causes of road accidents是复数概念，谓语动词也应用复数形式are．     
48．to 考查介词．pay attention to意为"注意"，是固定搭配．   
49．giving 考查动名词．without是介词，其宾接动词时用动名词形式，且signalling和giving表示选择关系．            
50．lanes 考查名词复数．根据语境可知，lane表示不止一条车道，要用复数形式．
51．dangerous 考查形容词．be动词后接形容词作表语．  
52．to concentrate 考查动词不定式．require sb．to do sth．意为"要求某人做某事"，后接动词不定式作宾语补足语．
53．drunk 考查形容词．be动词后接形容词作表语，drunk意为"醉的，喝醉的"．             
54．who/that 考查定语从句．分析句子结构可知这是一个定语从句，先行词someone在从句中作主语，用关系代词who/that．    
55．especially 考查副词．少数副词可以修饰名词及名词同等语，通常放在被修饰名词的前面，如：also，very，even，just，only，not，nearly，especially，exactly，s imply，rather，quite等．
