答案解析：
36. abroad
解析：此處應填副詞，與動詞travel構成完整語義。注意abroad的拼寫，不要誤寫成aboard。
37. worries
解析：空格前是some，可判斷應填名詞，還需考慮可能是復數形式。
38. bargaining
解析：空格前是the custom of，后面是over，可判斷應填一個動名詞。注意bargain的拼寫，尤其是ai不要誤寫成ei。
39. lower
解析：根據上下文的并列結構，此處應填動詞原形。
40. attempt
解析：根據上下文，an后應填入元音開頭的單數名詞。
41. stared
解析：根據上下文，此處應填入動詞充當謂語成分。注意要用過去時。
42. awkward
解析：此處應填入形容詞作表語。注意awkward的拼寫，k的一前一后分別有一個w。
43. strike
解析：空格位于be able to結構中to的后面，應填入動詞原形。
44. 標準答案：I came to the conclusion that such situations gave me a chance to be an informal ambassador for my country
聽音關鍵：conclusion, situations, chance, informal, ambassador, country

畫龍點睛：注意正確拼寫ambassador，當中的s是雙寫，包含雙寫字母的單詞是聽寫填空的常見考點。
