答案解析：
36. abroad
解析：此处应填副词，与动词travel构成完整语义。注意abroad的拼写，不要误写成aboard。
37. worries
解析：空格前是some，可判断应填名词，还需考虑可能是复数形式。
38. bargaining
解析：空格前是the custom of，后面是over，可判断应填一个动名词。注意bargain的拼写，尤其是ai不要误写成ei。
39. lower
解析：根据上下文的并列结构，此处应填动词原形。
40. attempt
解析：根据上下文，an后应填入元音开头的单数名词。
41. stared
解析：根据上下文，此处应填入动词充当谓语成分。注意要用过去时。
42. awkward
解析：此处应填入形容词作表语。注意awkward的拼写，k的一前一后分别有一个w。
43. strike
解析：空格位于be able to结构中to的后面，应填入动词原形。
44. 标准答案：I came to the conclusion that such situations gave me a chance to be an informal ambassador for my country
听音关键：conclusion, situations, chance, informal, ambassador, country
答案重构：I made a conclusion that such situations enabled me to act as an informal ambassador for my country
画龙点睛：注意正确拼写ambassador，当中的s是双写，包含双写字母的单词是听写填空的常见考点。
45. 标准答案：Bicycles, buses, people, and taxis fill the streets, dodging each other with constant narrow misses yet in many instances, the flow remains constant
听音关键：fills the streets dodging, constant, narrow misses, yet, remains constant

画龙点睛：本句话中有现在分词作伴随状语，结构较为复杂。
